摘要： A vented dock float and a method for providing one are provided. The dock float comprises a housing having a venting hole, a flange having a neck aligned with the hole, and a plug having a venting passage for controlling ventilation of the housing interior. The flange is spin-welded onto the exterior wall of the dock float at the venting hole. The float is then filled with light material through the flange neck. The plug having a venting passage is inserted in the neck in a non-sealing position for allowing gas trapped inside the dock float to vent out. Once the majority of the gas is vented out, the plug is moved to a sealing position to seal the dock float interior.

摘要： A torque reducer assembly including a ball screw assembly and a plunger gear assembly with a low torque allowing a single user to operate a hand wheel to open or close a valve under very high pressure without need of gear reduction and a Balance Stem. A gear shaft, ball screw, valve stem and gate are fixed from rotation with respect to each other but move axially together in response to rotation of a ball screw nut in the ball screw assembly. The plunger gear assembly rotates with the ball screw nut. In the engaged position, a plunger prevents rotation of the ball screw nut in the valve open direction but permits rotation of the ball screw nut in the valve close direction. In the disengaged position, the plunger permits rotation of the ball screw nut in the valve open direction and the valve close direction.

摘要： The valve operator assembly is provided for a valve and includes a housing, an input member rotatably mounted, and a transmission mechanism including a translating element and a rotating element connected to the input member, said transmission mechanism being adapted to convert applied rotation of the input member into axial translation of said translating element.The assembly further includes at least one locking mechanism radially interposed between the transmission mechanism and the housing, and provided with friction means in radial contact with the housing, and with at least one pre-stressing element acting on said friction means to maintain said radial contact. The pre-stressing element and the friction means cooperate together to lock the transmission mechanism with the housing in a static position of said assembly.

摘要： A valve operator assembly is provided for a valve and includes a housing, an input member rotatably mounted with respect to the housing, and a transmission mechanism having a rotating screw provided with an outer thread and a translating nut surrounding and coaxial with the screw, the nut being provided with an inner thread, the transmission mechanism being adapted to convert rotation of the screw into axial translation of the nut. The input member is mounted on the rotating screw. The assembly further includes an outer translating sleeve radially disposed between the housing and the translating nut and adapted to be connected to the valve translating member of the valve. The outer translating sleeve is provided with an inner thread and is connected to the translating nut so as to slide relative to the housing when the rotating screw rotates.

摘要： An actuating device or displacing a control device, such as a valve, gate valve or other control mechanism, in particular for use in oil or gas production systems, comprises a motor-gear unit (21) and a thread drive (22) which is operable by said motor-gear unit (21) and which comprises at least a threaded spindle (23) and a screw nut (24). The threaded spindle (23) is displaceable in an essentially axial direction so as to displace the control device (2) between a use position (7) and a non-use position (8, 9, 19, 20). To ensure a safe displacement into the non-use position in a simple way and independently of the pressure conditions prevailing between conveying medium and inner medium, the threaded spindle (23) is substantially axially displaceable beyond the use position (7) into a second non-use position (9). The invention also refers to a corresponding method for displacing the actuating device.

摘要： A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore.

摘要： The invention relates to a hand valve with a valve main body and a spindle movably arranged therein in at least in one actuating direction which can be adjusted for actuating the hand valve by means of a hand wheel arranged on the spindle in its position relative to the valve main body together with the hand wheel. The hand valve has a stroke limitation for the spindle with a stopper element which is adjustable in its position with respect to the valve main body. The invention is characterized in that the stroke limitation has a holding device for the stopper element which is held rotatable with the hand wheel, but fixed in its position to the valve main body in the actuating direction of the spindle at the valve main body.

摘要： An improved fluid control valve assembly employing a needle valve integrally formed on a non-rotating valve stem includes a metering orifice for engaging and forming a fluid seal with the valve needle, and a generally radially extending end face on the valve stem for engaging an opposing wall surface acting to positively stop the valve stem upon fully closing the valve and forming a seal between the metering orifice and valve needle to thereby avoid excessive loads and wear between the metering orifice and valve needle.
