Definitions

  • the invention relates to an actuator according to the preamble of patent claim 1.
  • actuators are e.g. Butterfly valves or ball valves in the beverage bottling industry.
  • disc valves or ball valves is often in at least one end position or movements of the closure element in or out of the end position to produce a very large or the maximum switching torque from the actuator, the one-sided against spring force or double-sided with pressure medium, e.g. Compressed air, can be acted upon.
  • pressure medium e.g. Compressed air
  • both guide rods are simultaneously and similarly loaded by the piston to transmit the reaction torque from the switching torque in the housing, regardless of the respective, depending on the stroke direction of the piston direction of the reaction torque.
  • Both equally long guide rods are anchored in the same cover, eg welded.
  • the free bending spiral lengths of the guide rods change inversely as the guide lengths.
  • the free bending spiral length is the decisive parameter for the bending loads or bending stresses to which the guide rod is subjected mainly in the area of anchoring in the cover but also in the penetration area into the guide. Regardless of the magnitude of the reaction torque, the bending loads on each guide bar are greatest when the free bend sweep length is greatest.
  • the reaction torque at the piston is highest when the free bending gyration at both guide rods is greatest, there is a risk of wear in the area of the anchorages and also in the mouth areas of the guides and there up the guide rods.
  • the guide rods are made of extremely heavy-duty and expensive material in the known actuator further.
  • the piston skirt is reinforced by a metallic outer support tube, whereby the number of parts of the actuator is increased inappropriately.
  • the lid in which the two guide rods are anchored is not made of the same expensive material as the guide rods themselves, the welding of two different materials is problematic, possibly such that an automated welding process can not be performed. Nevertheless, the risk of breakage in the respective weld remains acute, at the same time both guide rods, as both Guide rods are anchored in the same lid and at the same time subject to the highest bending forces in the operation of the actuator when their free Biegewirkzinn grow together. Often, the guide rods must be time-consuming rectified after welding, so they run properly in the guides.
  • the four guide rods which are radially equidistant from the piston axis, are diametrically opposed to each other in pairs, with one pair of guide rods circumferentially placed relatively close to a guide rod of the other pair, further limiting the amount of radians usable for the linkages in the piston skirt inexpedient.
  • the actuator is, mainly because of the four guide rods multipart and requires a time and cost intensive production.
  • the invention has for its object to provide an actuator of the type mentioned, which is very reliable, structurally simple and yet inexpensive.
  • the actuator consists of only a small number of parts and can be produced inexpensively, since, for example, the production of the anchoring area can be automated, and the guide rods may not need any messages. Since the respective reaction torque is introduced into the housing in a particularly stable manner in both stroke end positions of the piston, the torques to be transmitted from the actuator to the functional element, eg the closure member of a disk valve, can be very precisely predicted in terms of their values and characteristics, and on the switching behavior of the disk valve vote, for example so that these torques have their, preferably plateau-like, maxima at the stroke end positions of the piston.
  • the free ends of the two guide rods overlap in the stroke direction.
  • the overlap may, preferably, correspond to about one third of the outside diameter of the piston, or a multiple of the strength of the guide rods.
  • the guide rods are placed axially symmetrically and diametrically opposite with respect to the piston axis. In this way, the reaction torque is received symmetrically and transmitted into the housing.
  • the piston has a piston plate and a piston skirt containing the scenes and the guides, one guide their open mouth in the piston plate and its blind end in the piston skirt, whereas the other guide their open mouth in the piston skirt and her having blind end in the piston plate.
  • the two guide rods are immersed in the pistons from different sides, the formation of the guides ensures that pressure can not pass from one side of the piston to the other via the guides or linkages. In addition, this results in a largely symmetrical piston formation with sufficient meat around those areas in which forces are transmitted.
  • the piston can be acted upon by pressure medium via a pressure medium connection and against a return spring and / or on both sides via opposite pressure medium connections.
  • the piston movement takes place in a stroke direction by the pressure pulse from the pressure medium connection, and in the opposite direction by the return spring, optionally depending on either complete pressure relief in the pressure medium connection or a controlled pressure relief.
  • the piston in each stroke direction by a pressure pulse of a pressure medium, e.g. Compressed air, operated.
  • the torque to be transmitted depends on the angular position relative to a zero position.
  • the torque is usually the lowest within, for example, a 90 ° rotational adjustment between about 22 ° and 68 °.
  • the slope of each backdrop is usually steeper in both initial ranges but the same chosen as in an intermediate region of the backdrop.
  • practice shows that, for example, when the compressed air is applied to the piston against a return spring, and provision of the piston with the return spring, the torque from the displacement of the transverse axis in both initial areas of the scenes are different.
  • the slopes of the scenery in the initial areas are expedient steeper than in the intermediate area and chosen differently, so that the torque generated at the spring return and the torque generated upon application of compressed air at least largely the same size.
  • the bearing of the functional element and the actuator shaft and the connections of the functional element in the valve each set the same switching values or switching behavior in different ways, for example, operated by the actuator switching valve, for example, when the disc valve is designed by the actuator air-opening but spring-closing or air-closing but spring opening.
  • the pitch angles in the initial regions differ by about 2% to 10%, preferably about 5%, and the pitch angle in the intermediate section is about 60% of the pitch angles in the initial regions.
  • the steepest pitch angle is about 66 °, the pitch angle in the intermediate area about 38.9 ° and the less steep pitch angle about 63 °. With this difference, the pitch angle in the two initial areas can be at least largely produce the same torques when compressed air and spring return.
  • the largest pitch angle can be provided in an initial region where, in the stroke end position of the piston and at the slightest force of the return spring, the transverse axis engages the link.
  • the piston can be made of cost-effective and easy to process high-density polyamide.
  • the polyamide does not require fiber reinforcement, which, however, should not be excluded, e.g. to provide a glass fiber reinforcement in the piston.
  • each cover has a single receptacle for a guide rod end.
  • the guide rod is anchored with its end in the receptacle by welding, screwing, shrinking, gluing or caulking.
  • Anchoring can be done in an automated workflow be prepared and thereby with high precision, so that a message of the anchored guide rods is unnecessary.
  • the guide rod is anchored with its end in the receptacle of the lid by friction welding, preferably automated friction welding.
  • the friction welding process leads to a nearly monolithic anchoring and makes it possible to perform an exact positioning and alignment of the guide rod in the lid during friction welding, so that a message of the guide rod can be omitted.
  • the guide rods Thanks to the bending loads or bending stresses of the guide rods, which are reduced as a result of the design, they can be made of a cost-effective material, e.g. from a steel of specification 1.4301 or an at least substantially similar material.

  • the sliders 13 may be circumferentially angular over a radian, e.g. of 90 ° or more or less. Their slope can be uniform or variable. Its axial length is for example greater than the total stroke of the piston 2 in the housing. 1
  • the piston 2 converts its linear lifting movement into a rotational movement of the actuator shaft 25, wherein the actuator shaft 25 generates a constant or varying torque over the rotation angle, provided that the piston 2 is prevented during its strokes at a relative rotation about the piston axis.
  • two guide rods 6a, 6b are installed in the actuator A, which engage displaceably in guides 18a, 18b of the piston 2.
  • the guide rods 6a, 6b e.g. Solid rods with circular cylindrical cross section, e.g. made of a steel of specification 1.4301, or an equivalent material, are parallel to each other and as well as the guides 18a, 18b parallel to the axis of the piston 2 and to its stroke direction.
  • the guide rods 6a, 6b are e.g. placed symmetrically and diametrically opposite with respect to the piston axis and each anchored at one end.

  • the other guide rod 6b is anchored at one end in, for example, a receptacle 15 of the lower lid 4 and projects with its free end opposite to a guide rod 6a.
  • the free ends of both guide rods 6a, 6b overlap in a central region of the actuator A, for example with an overlap, which may be slightly shorter than a guide length xb, with the shown in the upper end position of the piston 2, the free end of the guide rod 6b in the Guide 18b is guided.
  • the guide length xa of the one guide rod 6a in the guide 18a is substantially equal to the projection length of the guide rod 6a.

  • the sum of the guide lengths xa + xb of the two guide rods 6a, 6b in the guides 18a, 18b has a certain value, but remains constant over the stroke of the piston 2, since the guide length xb increases to the same extent as the guide length xa of the guide rod 6a decreases, and vice versa.
  • the situation is similar with the free bending-wave lengths ya, yb, whose sum ya + yb also remains constant over the stroke of the piston 2.

  • a preferred method of anchoring is friction welding.
  • each guide rod is rotated in a tool under axial pressure in the receptacle 15 of the lid 3, 4, until under heat generated by friction, a welding process takes place, resulting in a nearly integral and monolithic welding region 16 leads, in which at least a significant part of the front end face and also a part of the peripheral surface of the end of the respective guide rod 6a, 6b with the material of the lid 3, 4 is welded.

  • This offers manufacturing advantages and on the one hand leads due to the high quality of the welding area 16, e.g. between very similar or the same materials, and the reduced bending loads for the guide rod 6a, 6b to increase the operational or process reliability of the actuator A.
  • an automated welding process it could alternatively be laser welded, perform inexpensively.
  • the diameter of the piston 2 or its stroke length and the length of the housing 1 depend on the applications and the required torques for the functional element G. Different torques for the functional element G may require actuators of different diameter (piston diameter), provided that a pressure medium actuation (With compressed air) is made, either a one-sided pressure medium applied against the return spring 17 or alternatively a double-sided alternating pressure medium.
