Definitions

  • the present invention concerns an improved plate [30] Foreign Application Priority Data component for use in a plate-type non-return valve Dec. [5, 1972 United Kingdom a. 57920/72 and Comprises "min, y Portion having at least one integral spring arm extending inwardly there- [52] U5, Cl 37 51 114 from with each said spring arm including at least one 511 im. c1. 1.
  • SHEET 1 [IF 4 VALVE PLATE COMPONENT WITH SPRING-ARM STRUCTURE
  • the present invention relates to an improved plate component for use in plate-type non-return valves such as are used in air compressors and the like machines.
  • the invention more particularly relates to a valve plate which when assembled in a valve has-frictionless guidance by virtue of the spring or resilient connection of the main body or valve closure portion of the plate to central portion or portions by means of one or more integral spring connecting arms.
  • a valve plate which comprises a main, annular body portion and at least one inwardly extending spring connecting arm integral with the main body portion and merging into a central hub portion.
  • the valve plate is of constant cross section although some plates have been produced with spring connecting arms having discontinuous, hollow-ground portions of restricted length.
  • the plate is secured in the valve housing by clamping the hub together with a guide washer and spring plates between the valve seat and the valve guard.
  • a plate component for use in a plate-type non-return valve comprises a main, outer body portion having one or more spring arms extending therefrom with the spring arm leading to a common inner portion or to a discrete inner portion and in which at least the portion of each spring arm lying within an annular region and/or substantially the whole length of each spring arm is of reduced thickness relative to the thickness of the main body portion of the component.
  • the plate component of the present invention will normally be a valve plate, it is intended that the present invention should include within its scope other plate components, such as damper plates, guide plates and spring plates and having any number of spring arms.
  • Each spring arm preferably includes at least one curved portion which is usually defined by concentric sides or edges although the spring arm may be of irregular width increasing from a central point to at least one connecting region with the main body.
  • the transition between the reduced thickness section of each spring arm and the main body portion is preferably a radiussed or slanted surface.
  • the inner portion or portions (hub) may also be of reduced thickness although will normally be of the same thickness as the main body portion and in such latter instance a radiussed or slanting transition surface will be provided between the spring arm and the inner portion.
  • the provision of radiussed or slanting transition surfaces reduces stress concentration and the likelihood of fatigue fractures.
  • the radiussed surfaces should have an as large as possible radius for best effect and the slanting surfaces, when provided, should have a low gradient.
  • a composite plate component comprises a valve plate having one or more spring connecting arms integral with and projecting from the main body of the plate, and an auxiliary spring member or guide plate having one or more spring or guide arms extending therefrom; the free end of each of said arms of the valve plate having interconnection means and being connected to a free end of the spring arms of the guide plate.
  • At least those portions of the spring arm or arms of the valve plate and/or guide plate lying within an annular region are of reduced thickness. Slanting or radiussed transition surfaces are provided between the reduced thickness portions and the other portions of the component.
  • the spring arms of i the plate component according to the invention advantageously exhibit improved flexibility and the operation and the versatility of valves including such components is considerably enhanced. Also, localised stressing is advantageously and significantly reduced as a result of the flexing or bending occurring over the whole length of the spring arm. The provision of radiussed or slanting faces further reduces localised stressing. Furthermore, in operation, a more even displacement of the component is advantageously achieved with any tilting effect being minimized or avoided. The tendency for the spring arms to twist is also reduced. The plate component accordingly has improved action and is less likely to sufi'er fatigue fractures.
  • the reduced thickness of the spring arms or of the spring arms and hub portion may be produced by suitable machining, for example, by means of a grinding wheel or by an electrochemical machining process or by etching. It should be noted that provision of the reucked thickness of at least those portions of the spring arm or arms lying within an annular region, in addition to providing an improved plate component, is also particularly advantageous from a production point of view since when, for example, machining with a grinder, the machining operation is a continuous operation for each plate, and is relatively simple and accordingly economic. The operation can also be readily effected on narrow spring arms such as those having two arcuate portions of different radii. Further a good surface finish is possible with such grinding operation and the valve plate is accordingly improved in such respect.
