Definitions

  • the invention relates to an automatic annular plate valve for reciprocating compressors, with several individual, concentrically arranged between the valve seat and catcher Plastic ring plates as closing organs, which come from the peripheral webs of the catcher ago loaded by individual steel coil springs against the valve seat.
  • valves have long been known (see for example US 3 507 486 A, EP-345 245 B or US Pat. No. 3,536,094 A) and enable with specially flow-optimized flow cross sections compared to conventional designs known (flat steel plate valves or sheet steel ring valves) for a given ring width, a significant reduction in ventilation losses.
  • the individual feathering of the individual ring plates also makes possible in an advantageous manner A variety of influences on the opening and closing behavior of the valves.
  • the ring plates are either on common Power distribution plates with a minimized number of coil springs with high power intensity feathered or individually, so directly by a over the circumference of the ring plates distributed attacking higher total number of coil springs of lesser strength.
  • Object of the present invention is to the mentioned disadvantages of the above mentioned known designs to avoid and in particular an automatic ring plate valve the type described to improve so that the individually feathered individual annular plates while maintaining the lowest possible ventilation losses safely out can be, without due to the formation of the springs due to the height or the associated dead space increases unreasonably.
  • a ring plate valve of the type mentioned above achieved in that the diameter of the coil springs substantially equal to or slightly smaller than the width of the ring plates at the support point is the spiral springs, and that the coil springs on the side of the catcher in individual, sitting in blind hole-like recesses of the peripheral webs of the catcher and in open state of the ring plates the space occupied by the coil springs at least are supported and guided largely outwardly final spring pots.
  • valve springs with a predefined force intensity over a given stroke range can at large spring outside diameter can be realized with a lower installation height than at small outer diameter.
  • the spring pots of thermoplastic or thermosetting plastics preferably polyamides, Polyphenylene sulfides, polyether ketones, phenolic resins or epoxy resins, which with filling or reinforcing materials, preferably carbon fibers, graphite, aramid or Fluoropolymers, are equipped to increase the abrasion resistance.
  • relative movements between coil springs and surfaces in contact can be used on both sides made of steel or similar hard materials to wear and subsequently to increased Risk of breakage.
  • the spring pots can according to a further embodiment of the invention on their Floor have a vent, which claimed by the coil springs Space over at least one at the bottom of the recesses of the peripheral webs of the catcher provided, in the outer and / or inner circumference of the peripheral webs opening opening Vent.
  • a vent which claimed by the coil springs Space over at least one at the bottom of the recesses of the peripheral webs of the catcher provided, in the outer and / or inner circumference of the peripheral webs opening opening Vent.
  • the bottom of the spring pots can in a further embodiment of the invention for automatic Centering of the coil springs conically formed at least in the region of the support be, which improves the guidance and support of the coil springs in a simple manner.
  • Fig. 1 shows an explosion shown partial section through an inventive annular plate valve
  • Fig. 2 shows a partial section through the same valve in the assembled state.
  • the illustrated automatic annular plate valve has three individual, concentric with each other between valve seat 1 and catcher 2 arranged plastic ring plates 3 as Closing organs, which from the catcher 2 ago by distributed over the circumference of individual Steel coil springs 4 are loaded against the valve seat 1.
  • the diameter of the coil springs 4 is substantially the same size or only slightly smaller than the width of the annular plates 3rd at the support of the coil springs 4, which at a certain required, predefined Force intensity over a given stroke range, the total spring length 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 peripheral webs 6 of the catcher 2 sitting and in the The state of the ring plates 3 (FIG.
  • the spring pots 7 may be made of thermoplastic or thermosetting plastics, such as polyamides, polyphenyl sulfides, polyether ketones, phenolic resins or epoxy resins consist of fillers or reinforcing materials, such as carbon fibers, graphite, Aramid or fluoropolymers, to increase the 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 consist of fillers or reinforcing materials, such as carbon fibers, graphite, Aramid or fluoropolymers, to increase the abrasion resistance and to avoid Damage to the springs are equipped.
  • the spring pots 7 have at their bottom 8 a vent opening 9 (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 peripheral webs 6 of the catcher 2 provided, here in the outer and inner circumference of the circumferential webs 6 opening Bleed opening 10.
  • This opening 10 is formed here by a at the bottom of the recess 5 provided stepped area whose diameter is still at least slightly larger than the width of the peripheral webs 6 at this point, so here the entire blind hole-like recess 5 respectively to the inner and outer peripheral surface of the circumferential webs 6 of the catcher is open.
  • the bottom 8 of the spring pots 7 is not in this case the smallness of the representation clearly recognizable way on the inside for automatic centering of the coil springs 4 conically formed at least in the region of the support, bringing the steadily under Preload standing springs 4 are simply positioned in the spring cups 7.
  • protective spring pots 7 so the diameter of the individual coil springs 4 is increased to the predetermined by the width of the ring plates 3 measure be, at the same time the fluidically advantageous taper of the circumferential webs 6 of the catcher 2 in the flow direction away from the valve seat can be maintained without that it at the catcher side bearing point of the coil springs 4 to Abnützungsproblemen could come.
  • the springs are from the gas flowed space, in which high Flow rates are present, shielded and in direct contact with the subsidized medium or with entrained in this abrasive or polluting Particles avoided.
