US Patent:

39932850, Nov 23, 1976

Filed:

Aug 18, 1975

Appl. No.:

5/605278

Inventors:

Richard William Conley - Pittsburgh PA

Assignee:

Rockwell International Corporation - Pittsburgh PA

International Classification:

F16K 2500

US Classification:

251 86

Abstract:

A gate valve includes a pair of identically shaped tapered discs defining a tapered self-locking axially translatable gate wherein each disc has an annular hardened seating surface which engages the mating surfaces on the valve body adjacent the flow ports. Tongues on the sides of the discs ride in vertical grooves on the valve body as the gate travels between a raised open and a lowered closed position. The discs of the gate are provided with a slot transverse to the flow ports which captures a T-head on the stem assembly, the slot being positioned in the gate interior radially within the seating contact area to thereby reduce the overall height of the valve.

Assignee:

Kerotest Manufacturing Corp. - Pittsburgh PA

International Classification:

F16K 122

US Classification:

251305

Abstract:

A molded polyethylene valve body has a flow passage connecting an inlet with an outlet of the valve body. A valve seat formed integral with the valve body surrounds the passage and a plastic valve disc is rotatably positioned in the passage for movement into and out of sealing relation with the valve seat to effect closing and opening of the passage between the inlet and outlet. A valve stem is nonrotatably connected at one end to the valve disc and extends through the valve body and projects upwardly therefrom to an upper end portion. An actuator cap is nonrotatably connected to the valve stem upper end portion. An external valve neck portion surrounds the upper end portion of the valve stem and is positioned on the outer surface of the valve body. The neck portion is adapted to rotatably receive and support the actuator cap. A pair of clamp-like leg members of the neck portion extend circumferentially around the surface of the valve body to connect the neck portion to the valve body.

International Classification:

F16K 504

US Classification:

251309

Abstract:

A polyethylene plastic valve has a molded cylindrical body portion with an internal chamber with inlet and outlet openings. A unitary plastic plug member is rotatably positioned in the chamber. The plug member has an actuator portion formed of impact resistant plastic material, and a plug portion formed of dimensionally rigid plastic material with a flow passage therethrough. The plug member has open and closed positions. Dual durometer valve seats are positioned on the plug member to close the inlet and outlet openings in the valve body. The actuator portion of the plug member extends upwardly through the chamber and seals the internal chamber at the top by means of a circumferentially extending flange portion. A bottom cover plate is fused to and seals the lower end of the internal chamber. The bottom cover is arranged to disengage from the valve body and relieve excess pressure build up in the lower end of the chamber.

International Classification:

F16K 1226

US Classification:

251288

Abstract:

A molded polyethylene valve body has a conduit portion and an annular portion extending upwardly from the conduit portion. A passageway extends through the conduit portion for the conveyance of fluid. A valve seat is formed in the conduit portion by a metal sleeve that is molded in the valve body to prevent separation of the sleeve from the valve body during sustained pressures. O-rings positioned in grooves around the metal sleeve are compressed by the plastic material during the molding process to effect a seal between the sleeve and the plastic valve body. An annular rubber sleeve insert is vulcanized onto the inner diameter portion of the metal sleeve. A plastic valve disc is centrally positioned in the conduit portion within the periphery of the rubber sleeve insert and is arranged to sealingly engage the rubber sleeve insert when the valve is moved to the closed position. A metal stem extends through the annular portion of the valve body and is connected to the valve disc. The upper end of the metal valve stem is molded into an actuator.

International Classification:

F16K 5100

US Classification:

251288

Abstract:

A valve includes a molded plastic body portion having an internal chamber with upper and lower portions. Fittings connect the valve to conduits of a piping system. A valve seat surrounds inlet and outlet openings in the chamber lower portion. A plastic plug member is rotatably positioned in the valve seat. The plug member is a molded unitary element. The valve body portion and plug member have a substantially uniform wall thickness throughout. The plug member includes an integral plug portion and an actuator portion which facilitates ease of disassembly of the valve for repair. The plug portion has a flow passage which communicates with the inlet and outlet openings in the valve seat and is rotatable between open and closed valve positions. Seals retained on the plug portion engage the valve seat in the closed position. The actuator portion includes shearable stops which permit 360. degree.

International Classification:

F16L 3318

US Classification:

285250

Abstract:

A valve includes a molded plastic body portion having an internal chamber forming a valve seat having inlet and outlet openings. A plastic plug member is rotatably positioned in the valve seat and has a flow passage which in the open position of the valve communicates with the inlet and outlet openings. Pipe fittings of the valve body communicate with the valve seat and are aligned with the inlet and outlet openings. Each fitting is coupled to a conduit of a piping system by a nut threaded into the respective fitting to urge a wedge-shaped collar into frictional engagement with the conduit. The nut surrounds the collar which is advanced by the nut into the fitting until a radial shoulder on the nut abuts the end of the fitting so that the end of the nut in the fitting applies a controlled compressive force upon a gasket seal to effect a fluid tight connection of the conduit to the fitting.
