| 241 | Pressure compensation/control for fail-safe gate valve | US10036997 | 2001-12-21 | US06598849B2 | 2003-07-29 | Loc C. Hoang; Jim E. Kilmoyer |
| A fail-safe gate valve for sub-sea use features a floating, pressure biased compensating piston whose movement prevents internal pressure buildup from opening movement of the gate. A pre-charged fluid chamber provides the bias on the balancing piston. Using unequal piston diameters reduces the charge pressure. The balancing piston is not connected to the gate so that internal pressures can be employed to act on a net area, which biases the gate toward its fail-safe position. | ||||||

| An apparatus for controlling lateral movement of a laterally translating component includes a first fixed housing that remains in a fixed position with respect to a central axis and a second housing interfaced with the laterally translating component that moves linearly along the central axis. The first fixed housing and the second housing together define a first fluid chamber and a second fluid chamber for containing fluid interconnected by a fluid channel. The second housing moves linearly between a first position along the central axis that defines a first size for the first fluid chamber and the second fluid chamber and a second position along the central axis that defines a second size for the first fluid chamber and the second fluid chamber to control flow of the fluid through the channel. The first size is larger than the second size. The second position of the second housing limits lateral movement of the second housing and the interfaced laterally translating component to a greater degree than the first position of the second housing limits the lateral movement of the second housing and the interfaced laterally translating component. | ||||||

| 254 | Vent valve and method of use | US14669442 | 2015-03-26 | US10006553B2 | 2018-06-26 | Robert Andrew Hunt; Kevin Read |
| A vent valve comprises a valve housing defining a vent port and a valve member mounted within the housing so as to define a fluid system chamber and an activation chamber with the housing. The valve member is biased towards a closed position, in which fluid communication between the fluid system chamber and the vent port is prevented, by fluid pressure within the fluid system chamber acting on the valve member. The valve member is biased towards an open position, in which there is fluid communication between the fluid system chamber and the vent port, by fluid pressure within the activation chamber acting on the valve member. The vent valve further comprises a pressure limiting arrangement associated with the activation chamber to limit pressure therein to a predetermined pressure value. | ||||||

| The multi-way valve comprises an upper valve body, a lower valve body and a rotary valve core. A valve seat ring is located in the rotary valve core and comprises a body. A first annular boss is arranged on an outer wall of the body, and a second annular boss is arranged on an inner wall. The upper surfaces of the first annular boss and the second annular boss are respectively flush with the upper surface of the body to form a sealing surface which fits with a sealing surface of the upper valve body in a sealed manner. An annular gap is formed between the lower surface of the first annular boss and the rotary valve core, so that liquid in the chamber and an oil incoming channel respectively acts on the lower surface of the first annular boss or the second annular boss to form a sealing load. | ||||||
| 256 | Latch for a Ball and Sleeve Plunger | US15400222 | 2017-01-06 | US20180112502A1 | 2018-04-26 | Garrett S. Boyd; Mitchell A. Boyd |
| An improved latch structure for a two piece ball and sleeve bypass plunger comprises a single retaining ring installed in a groove formed in the inside diameter of the sleeve portion of the bypass plunger. The cross section profiles of the groove and the associated retaining ring are smaller in the radial direction. The depth of the groove in the sleeve is substantially reduced to provide increased wall thickness and robustness of the sleeve along the diameter of the sleeve, thereby extending the useful life of the bypass plunger. | ||||||
| 257 | HYDRASEAL FRAC SEAL | US15848400 | 2017-12-20 | US20180112492A1 | 2018-04-26 | Don Atencio |
| A valve seal assembly that provides for external pressure to be introduced to an energized seal of a valve, and compress the seal against a gate with enough force to block any paths where sand and chemicals would otherwise travel into valve body cavity or void. The external pressure introduced through pressure fitting makes the parts move like piston forcing the parts to compress together eliminating the machined tolerances or gaps required for the gate to be opened or closed. The compression can be provided by hydraulic pressure devices through injection ports. A separate valve seal assembly can be provided for each face of the gate and both assemblies can be activated when the fluids are flowing (open position) and an upstream valve seal assembly activated when the gate is in a closed position. | ||||||
