Definitions

  • the invention relates to a pressure compensation vessel for Compensation of pressure fluctuations in liquid circuits, with one of an upper part and a lower part existing container, and one in the container provided membrane that the container interior in a Gas space and a liquid space divided.
  • the object of the present invention is a simple Manufactured and recyclable pressure compensation vessel to create that inexpensive until its use can be transported and stored.
  • the task is solved in that the tops and Bottoms separated from each other and stacked one inside the other are transportable and storable and only for use on site detachable with each other by clamping means are connectable.
  • the clamping means with a Clamping lever can be brought into the closed position the clamping ring has U-shaped legs, those with axially inward, converging Slants are provided, the top and the Lower part of their axially facing inner Edges have radially outward flares and the axially inward facing each other tapered slopes of the clamping ring with axial outward-facing bevels pointing away from each other the flanges can be brought into operative connection.
  • the clamping ring also has a safety lock that only allows opening at the factory. To can open the top and bottom of each other be separated.
  • the membrane is between the upper part and lower part fastened, preferably clamped.
  • the membrane has one on its radially outer edge Membrane bead on which in the clamping arrangement between Upper part and lower part prevented from slipping inside.
  • the clamp connection makes welding and a possible heat-related destruction or damage a possibly existing corrosion-inhibiting Avoid coating.
  • the pressure compensation vessel 10 shown in FIG. 1 consists essentially of a container 21 made of an upper part 12 and a lower part 16 assembled is. Between the upper part 12 and the lower part 16 is a membrane 13, preferably a rubber membrane, arranged. The membrane 13 divides the container 21 into a gas space 22 and a liquid space 23.
  • the Liquid space 23 usually contains water and the gas space 22 is an inert gas or air.
  • valve 11 can be, as shown in Figure 2.
  • valve 11 According to the invention, a so-called SNAP-IN valve is provided, as is customary for filling pneumatic vehicle tires is.
  • the gas is at a predetermined pressure which is above the membrane 13 on the existing in the water chamber 23 Water works.
  • the water space 23 is via a system connection 17 connectable to a heating system 32.
  • the gas space 22 is in the upper part 12 of the container 21 provided while the liquid space 23 in the lower part 16 is housed. Hence the size of the individual rooms 22 and 23 by the size of the upper part 12 and the lower part 16 determined. By a Change the size of the upper part 12 or the lower part 16 becomes a size determination determined by use of the gas space 22 and the liquid space 23.
  • a clamping ring 14 is provided as the clamping means a safety lock 15 is provided.
  • the security lock 15 has a Lever 30 on, with which the facing free Ends 31 and 31a of the clamping ring separated at one point 14 moved against each other in a closed position can be.
  • the circumference of the clamping ring 14 can through the security lock 15 known per se reduced and thereby closed.
  • the safety lock 15 is for this purpose with a lever 30 provided with which the open clamping ring 14 can be shortened can. To shorten the two ends 31 and 31a of the clamping ring 14 first against each other and then pulled over each other. After closing the tension ring 14, the two ends 31 and 31a are tight on top of each other. You will be in this position by the lever 30 held.
  • the lever 30 is in the area of the free end 31a articulated via a linkage 34 with the clamping ring 14 connected and provided with a snap latch 33.
  • the latch 33 is radial in an articulation 35 articulated to the articulation 34 with the lever 30 connected.
  • the linkage 35 of the snap bolt 33 radially inside to the linkage 34 of the lever 30.
  • the Safety lock 15 is so by the spring tension the clamping ring 14 held in its closed position.
  • the lever 30 with - not shown - securing means for example a cotter pin or a safety wire, connected to the clamping ring 14 and so in its position being held.
  • This backup can be done at the same time be sealed to prevent any manipulation to a large extent to avoid and if necessary to be able to prove.
  • the assembly of the pressure compensation vessels 10 is thereby much simplified and can be done by little trained Personnel.
  • the clamping ring 14 has legs 27 and 27a with a U-shaped cross section. With the U-shaped legs 27 and 27a are the two Flares 19 and 20 of the upper part 12 and the lower part 16 encompassed. The angle of inclination 24 of the U-legs 27 and 27a is slightly larger than the outside angle ⁇ than 270 °.
  • the pressure compensation vessel 10 is with the Clamping ring 14 is kept closed according to the invention.
  • the membrane 13 is radially outside with a membrane bead 18 provided, which is located outside of the container 21. With the membrane bead 18, the membrane 13 of the edges 25 and 26 between the upper part 12 and the Lower part 16 kept clamped.
  • the legs 27 and 27a of the clamping ring 14 are V-shaped axially inward, converging Provide slopes 29 and 29a.
  • the axially inward directed bevels 29 and 29a correspond to the axially outward, pointing away from each other Slants 28 and 28a of the flanges 19 and 20.
  • the edges 25 and 26 of the upper part 12 and the lower part 16 are under a predetermined form held against each other.
  • the legs 27 and 27a converge in a V-shape.
  • the membrane 13 seals the container 21 from. Form the upper part 12 and the lower part 16 thereby a gas and watertight room.
  • the membrane 13th provided with the membrane bead 18.
  • the membrane bead 18 preferably runs radially around the edge of the Membrane 13.
  • the membrane bead 18 is clamped by the held radially outward flares 19 and 20.
  • the membrane bead 18 is thus outside the Inside of the container.
  • the pre-pressure of the clamping ring 14 causes the membrane bead 18 tight and tight between the edges 25 and 26 trapped. Likewise, the upper part 12 and the lower part 16 held firmly against each other. Through this Bracket becomes such a high pressure during assembly applied that the container 21 in the operating state cannot be opened.
  • valve 11 is provided in the area of the upper part 12, as shown in detail in Figure 2.
  • This Valve 11 is preferably a known SNAP-IN valve in solid rubber design.
  • the gas space 22 is through this Valve 11 with an inert gas, preferably with Nitrogen, filled.
  • the gas can be under one predetermined pressure.
  • the system connection 17 is in the lower part 16 designed and has - not shown - Means for fastening pipes.
  • the container 21 is for use in smaller systems determines and has a capacity of preferably up to 70 liters of water.
  • tops 12 and lower parts 16 for transport and / or Storage can be stacked one inside the other. That for transportation required transport volume can be considerable be reduced. At the same time be at the place of assembly Labor capacity needed - in particular for production intended for developing countries - for Reduce overall costs. For assembly the pressure vessels 10 need no personnel Welder training more, reducing personnel costs can be significantly reduced.
