Definitions

  • Multi-way valve in particular sampling valve
  • the invention relates to a multi-way valve, in particular sampling valve having an inlet, an outlet and an intake outlet fed from the inlet, which can be shut off via a valve.
  • Such a valve is known for example from DE 20 2007 006 417 U1. With this valve, a sample can be taken from a vapor stream, wherein the vapor sample is cooled in a condensation chamber, so that the condensate can be removed from the valve.
  • the sampling valve is a block construction, which means that the inlet port, the outlet port and the port of the discharge outlet and the valve seat are integrally made of a block. Although this provides significant benefits, however, the high manufacturing costs are not justified in some applications. These are based on removing 75% of the material from a block of material when making the valve. Further valves are known from US Pat. No. 5,065,980 A, EP 1 253 417 A2 and DE 20 2009 017 967 U1.
  • the invention has for its object to provide a valve, in particular a multi-way valve, with valve seat, which is made faster and cheaper and yet meets the high demands on product safety.
  • the inlet and the outlet are provided on a pipe section that the pipe section has a circular cross section and the pipe section between the inlet and outlet has an opening in the pipe wall
  • the valve has a valve body with valve seat and the valve seat and the discharge outlet are provided in a base body and the main body is inserted with its inlet leading to the valve seat in the opening of the pipe wall.
  • the embodiment of the invention therefore provides that the sampling valve or the multi-way valve not in one piece, but to produce a piece of pipe and a body.
  • the pipe section has an opening into which the base body is sealingly inserted.
  • the essential advantage is achieved that a commercially available pipe section can be used, in which only the required opening must be introduced.
  • only the base body must be made of a block, but on the one hand much easier and therefore can be handled easier, on the other hand, the material waste is greatly reduced because of this body only about 50% of material must be removed.
  • the finished T-valve body according to the invention thus also has a lower weight, since the entire tube region has no superfluous material.
  • connection of pipe section and base body by means of a weld wherein advantageously the weld can be reworked on the inside of the pipe section.
  • a high weld quality is achieved by means of the TIG process. Due to the circular tube cross-section of the main body can be positioned with its inlet in all directions on the pipe section. The sampling outlet can thus project upwards, laterally, downwards or at any angle of pipe section.
  • the valve seat leading inlet can be produced in different dimensions.
  • the opening in the pipe wall is cut out by means of a laser.
  • the main body is welded by means of a laser in the opening.
  • an orbital laser can be used.
  • the laser is preferably a movable in space laser and / or has a deflectable in space laser beam. In this way, highly precise cutting edges can be produced in the pipe section, so that the base body can be used accurately.
  • the main body has a flange on its side leading to the valve and the inlet side.
  • this flange has a first section which sits snugly in the opening in the tube wall. This first section replaces the part cut out of the pipe wall.
  • the flange has a surrounding the first portion, this radially projecting edge, which rests on the outside of the pipe wall.
  • This flange ensures that the main body is placed on the one hand exactly on the pipe section and on the other hand dives exactly to the desired level in the pipe wall.
  • the orientation of the base body on the pipe section can be determined by the shape of the flange. It is thereby precluded that the pipe section is welded incorrectly positioned on the base body.
  • the thickness of the first section corresponds in a preferred manner to the thickness of the pipe wall, it is ensured that the inside of the pipe wall is exactly aligned with the surface of the first section inserted into the pipe section. Negative influences on the flow are thereby avoided.
  • the flange has the advantage that the laser for welding the base body with the pipe piece can be moved closer to the base body, so that the projection of the edge over the opening in the pipe section can be smaller.
  • the base body on its side facing the pipe piece has a circular shape adapted to the inlet bearing surface, the body can be seen in the circumferential direction at any point on the pipe piece and nestles optimally without the main body tangentially projecting from the pipe section Has sections that are easily polluted or contaminated and difficult to keep clean.
  • Figure 1 is a perspective view of a preferred embodiment of the invention
  • Figure 2 is a side view in the direction of arrow II of Figure 1;
  • FIG. 3 shows a cross section III-III according to FIG. 2;
  • FIG. 1 shows a multi-way valve, generally designated 10, which is designed as a sampling valve 12.
  • This has a pipe section 14 and a base body 16, which are interconnected.
  • the pipe section 14 has an inlet 18 and an outlet 20 and is formed in its cross-section circular and thin-walled.
  • the base body 16 is provided with a removal outlet 22, which opens out of a first valve chamber 24 of a valve body 26.
  • This valve body 26 also has a second valve chamber 28, which opens into the interior of the pipe section 14 via a valve inlet 30.
  • a valve web 32 Between the two valve chambers 24 and 28 is a valve web 32, on which a membrane for shutting off the valve and separating the two valve chambers 24 and 28 is pressed.
  • the base body 16 is surrounded by a flange 34 which has a first portion 36 whose thickness corresponds to the thickness of the pipe wall 38.
  • This first section 36 is radially surmounted by an edge 40 which rests on the outside of the pipe wall 38.
  • the immersion depth of the flange 34 is limited in an opening 42 in the pipe wall 38.
  • the first portion 36 of the flange 34 is dimensioned such that it sits gap-free in the opening 42, so that the base body 16 can be welded by means of a laser with the pipe section 14.
  • the weld can then be machined by engaging the inside of the tube on the inside of the tube wall 38, in particular electrolytically polished.
  • the opening 42 is also produced by means of a laser, wherein in the same clamping after production of the opening 42, the welding of the base body 16 with the pipe section 14 can take place. Since the cutting out of the opening 42 and the welding is carried out by means of a laser, relatively little heat is introduced into the components. In addition, since no re-tension of the pipe section 14 is required, there are no Umspannpers, and the welding can be done much more precise.
  • the easy accessibility of the weld through the pipe section 14 not only has the advantage that the weld can be processed on the inside, especially ground and polished, but also that a slight check of the weld can be done, that this can be X-rayed, for example.
  • the flange 34 has the significant advantage that you can zoom much closer to the base 16 with the laser, so that the supernatants can be made smaller.
  • FIG. 4 shows various embodiments and embodiments of the invention.
  • a plurality of pipe sections 14 are set to each other for illustrative purposes and these pipe sections 14 differently equipped with partly different valve bodies 26.
  • the valve bodies 26 may be arranged on the pipe sections 14 such that their extraction outlet 22 always protrude radially to the axis of the pipe sections, but in different radial directions.
  • the sampling valve 12 can be adapted exactly to the required needs, e.g. with regard to the routing, the quantities to be withdrawn, the type of valve, etc., adapted.
