PRESSURE REGULATOR

摘要

A pressure regulator (100) is provided. The pressure regulator (100) includes various features that reduce the risk of internal leaking The pressure regulator (100) includes a regulator body (101) including a fluid inlet (107) with a valve seat (106) and a fluid outlet (108) and a cap (102) coupled to the regulator body (101). The pressure regulator (100) also includes a diaphragm (103) with a first side (103a) exposed to the fluid inlet (107) and the fluid outlet (108) and a second side (103b) exposed to the cap (102). The diaphragm (103) can frictionally engage the regulator body (101) to form a fluid tight seal. Additionally, the diaphragm (103) may include a socket (118) formed in the diaphragm (103) and a valve member (105) including a valve stem (110) with a ball (118) that is adapted to engage the socket (118) formed in the diaphragm (103) in order to couple the valve member (105) to the diaphragm (103).

主权项

1. A pressure regulator (100), comprising:
a regulator body (101) including a fluid inlet (107) and a fluid outlet (108); a cap (102) coupled to the regulator body (101); a diaphragm (103) positioned within the regulator body (101) and including:
a first side (103a) exposed to the fluid inlet (107) and the fluid outlet (108);a second side (103b) exposed to the cap (102); anda retaining rim (120) configured to frictionally engage the regulator body (101) to form a substantially fluid tight seal between the diaphragm (103) and the regulator body (101); a biasing member (104) coupled to the second side (103b) of the diaphragm and the cap (102); a valve member (105) including a valve stem (110) extending through the fluid inlet (107) and coupled to the diaphragm (103); a ball (117) formed at the second end of the valve member (105) and a socket (118) formed in the diaphragm (103), wherein the ball (117) is configured to engage the socket (118) to couple the valve member (105) to the diaphragm (103); a stem receiver defined by the diaphragm proximate the socket; and a channel defined by the diaphragm disposed proximate the socket and stem receiver, wherein the channel is substantially orthogonal to the first side of the diaphragm and located between the socket and the biasing member, wherein the channel defines an outer surface of a tab defined by the diaphragm, wherein the tab is configured to allow a proximate fluid pressure to compress the tab around the ball and the valve stem.
