Definitions
- the invention relates to an automatic ring plate valve for piston compressors, with several individual, arranged concentrically to each other between the valve seat and catcher Plastic ring plates as closing elements, which come from the circumferential webs of the catcher are loaded against the valve seat by means of individual steel spiral springs.
- valves have long been known (see for example EP-345 245 B or US 3 536 094 A) and enable with flow-optimized cross sections compared to usual known constructions (flat steel plate valves or sheet steel ring valves) with a given ring width, a significant reduction in ventilation losses.
- the individual springing of the individual ring plates also enables more advantageous Various influences on the opening and closing behavior of the valves.
- the ring plates are either common Power distribution plates with a minimized number of coil springs with high force intensity spring-loaded or individually, that is, directly through one over the circumference of the ring plates distributed attacking higher total number of coil springs of lower force intensity.
- the object of the present invention is to overcome the disadvantages mentioned at the outset to avoid known designs mentioned and in particular an automatic ring plate valve to improve the design described so that the individually sprung individual ring plates safely guided while maintaining the lowest possible ventilation losses can be made without the height or the associated harmful space increases unreasonably.
- a ring plate valve of the type mentioned in that the diameter of the coil springs essentially the same size as or slightly smaller than the width of the ring plates at the support point of the coil springs, and that the coil springs on the side of the catcher in individual, seated in blind hole-like recesses of the circumferential webs of the catcher and in open state of the ring plates at least the space occupied by the coil springs spring pots are largely supported and guided to the outside.
- valve springs with a predefined force intensity over a given stroke range large spring outer diameter with a smaller installation height than at small outside diameter.
- the spring cups mentioned in the blind hole-like recesses of the circumferential webs of The catcher prevents the spring ends on the catcher side from being securely supported with the usually at a greater distance away from the ring plates for flow reasons allows thinner catcher circumferential webs.
- the individual Spiral springs are safely guided in these spring cups and against environmental influences, for example well protected by hot or aggressive gases to be controlled.
- the spring cups made of thermoplastic or thermosetting plastics, preferably polyamides, There are polyphenyl sulfides, polyether ketones, phenolic resins or epoxy resins, which with fillers or reinforcing materials, preferably carbon fibers, graphite, aramid or Fluoropolymers are equipped to increase abrasion resistance.
- relative movements between coil springs and surfaces in contact ring plate, spring base and essentially cylindrical spring test side surfaces
- the spring cups from wear-resistant and wear-reducing Plastics with special additives are the spiral springs on everyone Potential contact areas are well protected from abrasion.
- this is direct surfaces in contact with the spiral springs on the bottom of the spring cup and on the plastic ring plate the case; on the other hand, this also applies to potential contact areas between Spring outer surface and inner spring inner surface for the event that during the ring plate movement initiates a rotation thereof, which is a deflection the spring ends in the circumferential direction.
- the catcher turns on the places of potential micro-movements due to the plastic spring cups from wear protected.
- the spring cups can according to a further embodiment of the invention on her Bottom have a vent that the claimed by the coil springs Space over at least one at the bottom of the recesses of the circumferential webs of the catcher provided opening opening into the outer and / or inner circumference of the circumferential webs Vent.
- This ensures in a very simple manner that, for example, pressure waves in the spring nest, which are initiated by the ring plate dynamics, are avoided.
- the deposits of oil, dirt or oil entering the spring nest the like are discharged via the vent path mentioned.
- a further embodiment of the invention is from particular advantage, according to which to form the in the outer and inner circumference of the Circumferential webs of the catcher opening out the recesses in the circumferential webs of the catcher have a stepped area on the bottom, its diameter is even larger than the width of the circumferential webs at this point. This enables a very easy manufacture of the necessary vents, with the spring pots still can rest securely on the gradation of the recess on the floor.
- the bottom of the spring cups can be activated automatically Centering of the coil springs at least in the region of their support is conical be what simply improves the guidance and support of the coil springs.
- Fig. 1 shows an explosive shown partial section through an annular plate valve and Fig. 2 shows a partial section through the same valve in the assembled state.
- the illustrated automatic ring plate valve has three individual concentric to each other arranged between valve seat 1 and catcher 2 plastic ring plates 3 as Closing members, which from the catcher 2 by means of individual distributed over the circumference Steel coil springs 4 are loaded against the valve seat 1.
- the diameter of the coil springs 4 is essentially the same size or only slightly smaller than the width of the ring plates 3 at the contact point of the coil springs 4, which means that a specific, predefined one is required Force intensity over a given stroke range the total spring length is relatively low can be held.
- the coil springs 4 are on the side of the catcher 2 in individual, in blind hole-like recesses 5 of the circumferential webs 6 of the catcher 2 seated and in the open State of the ring plates 3 (Fig.
- the spring cups 7 can be made of thermoplastic or thermosetting plastics, such as polyamides, polyphenyl sulfides, polyether ketones, phenolic resins or epoxy resins exist, which with fillers or reinforcing materials, such as carbon fibers, graphite, Aramid or fluoropolymers, to increase abrasion resistance and to avoid Damage to the springs are equipped.
- thermoplastic or thermosetting plastics such as polyamides, polyphenyl sulfides, polyether ketones, phenolic resins or epoxy resins exist, which with fillers or reinforcing materials, such as carbon fibers, graphite, Aramid or fluoropolymers, to increase abrasion resistance and to avoid Damage to the springs are equipped.
- the spring pots 7 have a ventilation opening 9 on their base 8 (see the cut spring cup 7 in Fig. 2), which claimed by the coil springs 4 Space over at least one at the bottom of the recesses 5 of the circumferential webs 6 of the catcher 2 provided, here opening into the outer and inner circumference of the circumferential webs 6 Vent opening 10.
- This opening 10 is formed here by one at the bottom of the recess 5 provided stepped area, the diameter of which is at least slightly is larger than the width of the circumferential webs 6 at this point, with which the entire Blind hole-like recess 5 each to the inner and outer peripheral surface of the peripheral webs 6 of the catcher is open.
- the bottom 8 of the spring cups 7 is not here in accordance with the smallness of the illustration clearly recognizable on the inside for automatic centering of the coil springs 4 at least in the area of their support is conical, with which the steadily below Prestressed springs 4 are simply positioned in the spring pots 7.
- the spring cups 7 can, for example simply thereby in the associated recesses 5 of the circumferential webs 6 of the catcher be kept that the outer diameter is chosen slightly larger than the diameter the recess, making it very light and simple, especially with plastic spring pots clamping can be achieved.
- the feathers as described are also harmful
- Protective spring pots 7 can be the diameter of the individual coil springs 4 enlarged to the size predetermined by the width of the ring plates 3 are, at the same time the fluidically advantageous tapering of the circumferential webs 6 of the catcher 2 can be maintained in the flow direction away from the valve seat that there are wear problems at the catch side of the coil springs 4 could come.
- the springs are from the gas-flowed room, in which high Flow velocities are present, shielded and in direct contact with the conveyed medium or with abrasive or soiling carried in it Avoided particles.
