发明名称 Tap for receivers of gases compressed or liquefied under pressure
摘要 A moveable control lever (4) made of PVC operates a helical movement in the body (1) and has a skirt to keep turbulence outside the housing (18). The valve itself is made of a hard needle and a PTFE seat, which naturally and durably seal by the geometric superposition of these two conical surfaces. An leakage is contained locally by the control skirt until the tap is closed - DETAILED DESCRIPTION - A moveable control (4) at the top made of plastic such as PVC, operates a helical movement sliding around the body (1) which has at its base a skirt (4A) keeping turbulence outside the housing (18). In the middle of the control is a square hole into which fits the square part of the mechanism (5) of the needle yoke (2B) of the static link (2, 3). The control also has a six-sided hole (16) to fit the shank of the tap handle (17). The static needle made of hard material and the seat made of PTFE is naturally and durably sealed by the continuity of the wall of confinement guaranteed by the geometric superposition of these two conical surfaces. Any leakage is localized in the seat by the control until the tap is closed. A filter sock (14) fits between the inlet to the body to stop solid particles in suspension in the fluid
