Definitions

  • the invention relates to a cartridge valve for a radiator, in particular for a sectional radiator, with a valve seat assembly, a cooperating valve element, a presetting and a housing, wherein the housing has a lateral first opening, which is connected to a side facing away from the valve element of the valve seat assembly, and a second opening which is connected via an annular space partially surrounding the valve seat with a valve member facing side of the valve seat assembly.
  • Such a cartridge valve is known for example from DE 10349 925 A1.
  • the first member of this radiator is usually used as a riser.
  • the cartridge valve therefore has a lateral first opening through which, for example, the heating water flowing through the riser pipe can reach the valve seat, so that the valve element is flowed through the valve seat. The then heated by the valve element heating water can flow through the second opening in the other parts of the radiator.
  • such a built-in valve uses a presetting device, which can be used, for example, to limit the flow of heating fluid to a specific value.
  • this presetting device is formed by an insert which is rotatably arranged in the housing and has a lateral inlet opening which is brought into a larger or smaller overlap with the inlet opening of the housing. that can.
  • an engagement of the side of the cartridge valve is required, which is arranged with the cartridge mounted in the radiator.
  • the object of the invention is to enable presetting in the installed state.
  • the presetting means comprises an adjustable adjustment in the housing, which covers the annulus with an adjustable coverage.
  • the default setting is made, so to speak, on the other side, usually the outflow side of the valve seat assembly. Since this side, on which the adjusting element is arranged, faces the side of the installation valve, which protrudes from the radiator in the installed state, the access to the adjustment element is then also possible in the installed state. It is therefore possible to realize the presetting in the same way or in the same way as with other radiator valves, which are not designed as a cartridge valve. Also results in a correspondingly good control using the adjustment.
  • the adjusting element is designed as a curved screen.
  • the shape of the screen must not have been generated by bending. The wording is intended only to express that the screen has a curved course in plan view. This can be achieved in a simple manner, the rotatability of the adjusting element in the housing.
  • a curved screen for example, be performed parallel to the inner wall of the housing, so that it always occupies the same distance from the housing, regardless of the angle of rotation, which takes the adjustment to the housing.
  • the screen has a shape that follows the course of the annular space.
  • the annular space is usually formed at least partially circular, so that the screen can be bent accordingly.
  • the adjusting element preferably has a smaller length in the circumferential direction than the annular space. This ensures in a simple manner that you always have a flow through the valve, regardless of the position of the adjustment. This avoids dangerous situations and malfunctions, even if a fitter makes an incorrect attitude due to ignorance or negligence.
  • the adjustment member extends over a range of 180 °. This makes the setting relatively easy. It is known that the screen extends over half the circumference. If one then knows the position of the screen, for example by an externally visible position mark, then one also knows to what extent an overlap has occurred.
  • the adjusting element is preferably fastened to a holding element arranged in the housing, which encloses a valve spindle carrying the valve element. To adjust the adjustment, you have to rotate only the holding element in the housing.
  • the retaining element is adjustable from the outside.
  • disassembly of the cartridge valve to change the default setting is not required.
  • the holding element has a torque application device, in which engages a further element which is accessible from the outside. The holding element itself must therefore not even directly accessible from the outside, if you can operate it indirectly.
  • the valve seat assembly has a plurality of valve seats. This allows the maximum flow through the valve to expand.
  • valve seats are arranged on a circular line. This facilitates the production. At the same time there is a uniform outflow of the water flowing through the valve.
  • the valve seat arrangement has a central valve seat and at least one valve seat arranged radially further outward.
  • the radially further outwardly arranged valve seat corresponds to the "usual" valve seat.
  • the inner valve seat forms a kind of "nozzle", so that in turn a kind of double-seat construction is formed, with which the capacity of the valve can be increased.
  • the presetting may only act on a part of the water flowing through the cartridge valve. But this is easily acceptable.
  • FIG. 1 shows a first embodiment of a cartridge valve
  • Fig. 2 shows a second embodiment of a cartridge valve
  • FIG. 3 shows a third embodiment of a cartridge valve.
  • 1 shows a first embodiment of an installation valve, wherein FIG. 1a shows a section BB according to FIG. 1b and FIG. 1b shows a section AA according to FIG. 1a.
  • the cartridge valve 1 has a housing formed from an upper part 2 and a lower part 3.
  • a lateral first opening 4 is arranged, through which heating liquid can flow in the direction of an arrow 5 as a rule.
  • the first opening 4 will therefore also be referred to below as the "inflow opening", this name being used for reasons of simplicity.
  • a cartridge valve 1 is mounted in a horizontal position, so that the arrow 5 points vertically upwards and accordingly water, which is supplied from a riser or the first member of a sectional heating element, can enter the cartridge valve 1.
  • the inflow opening 4 opposite a deflection surface 6 is arranged, through which the inflowing water is deflected practically at right angles to a valve seat 7.
  • valve element 8 which is fastened to a valve spindle 9, acts together.
  • the valve spindle 9 is pushed away from the valve seat 7 by a known opening spring 10.
  • the valve element 8 is moved toward the valve seat 7 only when a force is exerted externally on the valve spindle 9, for example by an actuating rod 11 which is guided by a stuffing box 12.
  • On the actuating rod 11 normally acts an actuator of a thermostatic attachment, not shown. This can work in different ways, for example with an expansion element, in an electrical way, and use a room temperature and / or a water temperature.
  • the valve spindle 9 is held in a holding element 13.
  • the retaining element 13 encloses the valve spindle 9 and at the same time forms an abutment for the opening spring 10.
  • the retaining element 13 is rotatable but axially fixed in the housing consisting of upper part 2 and lower part 3.
  • valve seat 7 is arranged on a valve seat carrier 14, which is connected only in the region of the inflow opening 4 with the lower part 3 of the housing, but otherwise forms a ring space 15 with the lower part 3 of the housing, by the heating water, the gap between Valve element 8 and valve seat 7 has flowed through, can flow.
  • the effluent through the annulus 15 water then passes to a frontal second opening 16, which is hereinafter referred to for the sake of simplicity as "outflow", and from there to the radiator, which is to be supplied with the heating water.
  • the lower part 3 may be formed from a plastic, for example by casting or injection molding. Other materials, in particular a metal, such as brass, are possible.
  • the connection between upper part 2 and lower part 3 can be made via a thread pairing. A locking connection, an adhesive or welded connection, a pressing or the like is possible. If the lower part 3 made of plastic and the upper part 2 are formed of metal, it may be useful to attach a small plastic ring on the upper part 2, and then to connect the lower part 3 and the plastic ring by ultrasonic welding.
  • an adjusting element 17 is arranged, which is designed as a curved screen and extends over approximately 180 ° in the circumferential direction.
  • the adjusting member 17 has a radial extent or thickness which is about the radial extent or Thickness of the annular space 15 corresponds.
  • the adjusting element 17 can therefore cover the annular space 15 more or less in dependence on the rotational position of the holding element 13. The least coverage results when the adjustment 17 has the greatest possible coverage with the attachment of the valve seat support 14 on the lower part 3 of the housing. The greatest possible blocking effect is obtained when the adjusting member 17 has been completely rotated over the annular space 15, so that only a portion of the annular space remains free, which exceeds 180 °.
  • the holding element 13 has a torque application arrangement 18, in which an adjusting element 19 engages, which protrudes from the upper part 2 of the housing.
  • a fitter can take either directly or by means of a Einstellhandhabe 21, the adjusting element 19 and rotate, whereby the retaining element 13 and thus the adjustment member 17 in the housing 2, 3 is rotated, so that the default is changed.
  • the adjusting member 17 must not complete the annular space 15 in the radial direction.
  • the task of the adjusting element 17 is to provide a throttle resistance for the heating fluid, with which the flow of the heating fluid through the cartridge valve 1 can be throttled as a whole by a default setting.
  • FIG. 2c shows a modified embodiment of the cartridge valve 1
  • the shape of the adjustment member 17 and the annular space 15 is unchanged from the embodiment according to FIG. 1.
  • Fig. 2 shows a modified embodiment of the cartridge valve 1, which differs from the cartridge valve 1 of FIG. 1 in that a plurality of valve seats 7a-7f are provided, all of the same valve element. 8 can be covered or released.
  • the valve seats 7a-7f are attached to the valve seat support 14, which, except for the number of valve seats, that of FIG. 1 corresponds.
  • Fig. 3 shows a third embodiment in which a difference from the embodiment of FIG. 1 is that in addition to the valve seat 7, can flow through the liquid radially outward into the annular space 15, radially further inside an additional valve seat 7g is provided which encloses a discharge nozzle 22 through which heating water can also flow. Also, the valve seat 7g cooperates with the valve element 8.
  • the adjusting element 17 can exert only a throttle effect on the part of the heating water, which flows through the annular space 15, ie radially outward. However, this is usually sufficient to make a default.
