Embodiment Construction

[0013] The basic design of the ring valve 1 is already known, so only a brief description will be given here with reference to FIGS. 1 and 2 . For example, an annular valve 1 used in a compressor consists of a valve seat 3 and a valve opening limiter 2 . A valve element 4 is installed in between, the valve element can move back and forth between the valve seat 3 and the valve opening limiter 2, and together with the valve seat 3 undertakes the sealing function, wherein the valve element closes and opens through the ring valve 1 flow cross section. The individual parts of the ring valve 1 are assembled together via a through screw 8 and a nut 10 . The distance between the valve seat 3 and the valve opening limiter 2 and the possible valve stroke are adjusted through the spacer 9 , or through the valve opening limiter 2 or the axial projection on the valve seat 3 . An annular passage 13 is arranged in the valve seat 3 , and an annular outflow passage 14 is arranged in the valv...

Abstract

Simple refinishing of the valve seat 3 of an annular valve 1 is made possible, which has a plurality of ring guide studs 15 arranged radially and separated in circumferential direction and projecting from said valve seat 3 to guide sealing rings 5 in radial and axial direction, whereby a recess 18 is provided in the valve seat 3 extending in circumferential direction between to ring guide studs 15 lying at the same radius. No cross piece negatively influencing the outgoing flow must remain between the sealing surfaces 17 in the area of the recess 18 during refinishing of said sealing surfaces 17 of the valve seat 3.

Description

technical field [0001] The invention relates to an automatic annular valve, which comprises a valve seat, a valve opening limiter, and a plurality of concentric sealing rings arranged between the valve seat and the valve opening limiter and capable of moving back and forth. The seat seals cooperate together, and includes a plurality of ring guide protrusions distributed in the radial and circumferential directions on the valve seat, and these ring guide protrusions protrude from the valve seat in the axial direction for radial and axial movement. The sealing ring is guided; the invention also relates to a method for producing, trimming the valve seat of the ring valve. Background technique [0002] The valve element of an annular valve (especially an annular valve used in a compressor) can be designed as a valve plate with a row of annular holes, or can be composed of several independent concentric sealing rings. It is known that when concentric sealing rings are used, a sy...
