| 103 | Rotary Ceramic Valve | US14138873 | 2013-12-23 | US20140183395A1 | 2014-07-03 | Robert C. Popke; William S. Sankey |
| A rotary ceramic tube valve is disclosed. The valve may have an outer shell and an inner ported cylinder which move in relation to each other of open and close ports on the valve. By turning the inner ported cylinder in relation to the outer shell, different orifices in the outer tube may be opened or closed. By coating the inner surface of the outer tube and the outer surface of the inner ported cylinder with a ceramic coating, friction in the valve may be reduced resulting in longer life, less heat generation, tighter tolerances and more reliable long term operation. Further, inner rotor 200 may also have cylindrical pressure balancing seals and related pressure communicating paths that provide counterforce to reduce stress on the bearings. | ||||||
| 104 | Automatic back water valve system | US260429 | 1999-03-01 | US6131595A | 2000-10-17 | William H. Cook |
| A valve body is formed in two half sections which are secured together to define a water passage and to confine therebetween a thin gate valve blade for movement between a lower open position and an upper closed position. An actuator includes a flexible bellows sealed to the valve body above the passage and a top plate connected by a rod to the valve blade. The valve body and the bellows define an expandable fluid chamber connected by a bottom port or line to a drain line. The valve body is installed within a water supply line or a sewage drain line extending under a floor. In the event sewage water backs up within the drain line, air within the fluid chamber is compressed to expand the bellows upwardly for closing the valve. When the sewage water flows from the drain line, the air pressure reduces, and the bellows collapses and automatically returns the valve blade to its open position. | ||||||
| 105 | Regulating Valve | US448058 | 1995-05-23 | US5529026A | 1996-06-25 | Klaus Kurr; Karl-Heinz Spies; Wolfgang Krause |
| A regulating valve, comprising a housing having a cylindrical valve chamber, is disclosed. The valve chamber is provided with at least one inflow and at least two outflow ports. The inflow and the outflow ports can be at least partly closed off as required by a single common valve body arranged in the valve chamber that can rotate about an axis. The valve body acts as a rotary valve and can be actuated by a drive. The inflow and/or at least one of the outflow ports is surrounded on the side of the housing facing the valve body by a seal. The seal can be brought into sealing engagement with the valve body under an elastic preload. The valve body has an extension in the peripheral direction of the valve chamber that is delimited in each case by an edge, such that the flowoff edge passing over the inflow port while it is opening has an axially extending elliptical indentation. | ||||||
| 106 | Flow stabilized, retractable seal, double-block and bleed plug valve | US187892 | 1994-01-28 | US5385332A | 1995-01-31 | Gordon M. Smith |
| Fluid pressure changes are imposed on selected interior surfaces of a plug passageway of a plug valve to create torque. In one embodiment perturbations are provided in selected flow surfaces of the valve plug to create turbulent boundary layer flow along such surfaces which generates a beneficial stabilizing torque tending to reduce or eliminate holding forces conventionally provided by mechanical parts such as detent mechanisms. In another embodiment, pilot holds between interior and exterior plug surfaces are used to alter the fluid pressure at diagonally opposite locations relative to the plug rotation axis to produce the stabilizing torque. | ||||||
| 107 | Tapered plug valve | US34764 | 1993-03-19 | US5312086A | 1994-05-17 | Keith J. Hollingworth |
| A tapered plug valve comprising a tapered plug rotatably mounted within a bore in a valve body to intercept a passageway. Spacing means is provided to limit the amount of axial movement of the plug and biassing e.g. spring means is provided to apply an axial force to the plug. | ||||||
| 108 | Non-locking tapered plug valve | US774145 | 1985-09-09 | US4614330A | 1986-09-30 | Manmohan S. Kalsi; Clemens L. Horst |
| A non-locking tapered plug valve is provided which prevents taper locking of the plug member by ensuring against pressure responsive plug movement toward the small extremity thereof due to positive or negative hydraulic pressure transients. The chambers at each axial extremity of the plug member are of such volumetric relation during positive pressure transients that the chamber at the small extremity of the plug reaches equilibrium with flow passage pressure before the chamber at the large extremity of the plug member thus ensuring that any pressure responsive resultant force acting on the plug member is directed toward its large extremity. To avoid taper locking during a negative pressure transient, an equalization passage with a check valve is provided to permit unidirectional flow from the large extremity of the valve chamber to the main flow passage. This allows a quicker equalization of pressure between the large extremity of the valve chambers with line pressure, whereas the higher pressure in the small extremity of the valve chamber creates a force on the plug member away from the taper locking direction. | ||||||

| Disclosed is a plug valve comprising displacement means (5) allowing equalization of upstream and downstream pressures existing on the plug (3), said equalization means being applied before the plug has been moved. | ||||||
| 110 | Four-way plug valve | US248313 | 1981-03-27 | US4385746A | 1983-05-31 | Jerry B. Tomlin; Herbert H. Hodgeman |
| A rotary lift-turn type plug valve mechanism includes a valve body and bonnet structure defining a tapered valve chamber that receives a tapered plug member which is operated by linear and rotary components of movement to achieve valve operation. Externally adjustable plug positioning means is provided by the valve mechanism to enable the position of the plug element to be adjusted relative to the inlet and outlet flow passages defined by the valve body. Plug dampening means is also provided for applying a dampening force to the plug element to prevent slamming of the plug upon reaching the end of a rotational component of movement. A valve actuator is also provided that operatively engages the valve stem of the plug and is capable of imparting both linear and rotary components of movement to the valve stem for unseating, rotating and reseating the valve element within the valve chamber. A system is provided for maintenance of predetermined pressure differential across the sealing elements of the valve and to compensate for volumetric changes as the valve element is seated and unseated. | ||||||
| 111 | Manifold assembly for compressed air storage tank or the like | US842661 | 1977-10-17 | US4120319A | 1978-10-17 | Joseph L. Krechel; Michael J. Purvis |
| A manifold assembly for a compressed air storage tank or the like having a main flow passage therethrough, ball valve means and pressure relief means. The ball valve means comprises a ball valve member received in a lateral bore extending generally perpendicularly through the passage. The ball valve member has a spherical ball portion with an aperture therethrough and a pair of circular sealing heads, one on each side of the ball portion. Each of the sealing heads carries a seal which is slidably and sealingly engageable with the walls of the lateral bore. The sealing heads are of substantially equal diameter so that pressure forces acting on the ball valve member which tend to move the latter axially within the bore are balanced. A seal body is insertable into a main flow passage of the valve body from one end thereof for sealingly engaging the ball portion after the ball valve member has been installed in the lateral bore. | ||||||
