The present invention provides a seal gasket which is inserted between the ball valve body and the seat retainer in the cryogenically cooled liquefied natural gas ball valve to prevent the leakage of fluid so that the seal gasket can be cured and contracted under the influence of cryogenic temperature to prevent the fluid from leaking. A seal gasket mechanism. Natural gas is transported through pi...
JST seals produce high-quality throttle valve and gate valve equipment seals. Choke packing throttle valve are control valves for production wells, which are used to control the flow of well fluid under production. The throttle valve also compresses the pressure from the reservoir and regulates the downstream pressure in the flow line. Choke packing is available in a variety of types and material ...
The convertible rotary seal has a housing for receiving the polishing rod. A mandrel is rotatably mounted in the seal housing and surrounds the polish rod. A wear sleeve surrounding the mandrel engages a primary seal. A secondary seal engages the mandrel and polish rod and rotates therewith but may be converted for use as a static seal if necessary. A locking mechanism selectively secures the mand...
BOP seal, also known as Blowout Preventers Seals, is generally used for large special valves or mechanical devices to seal, control and monitor oil and gas wells to prevent blowout and rig safety. Because there are many uncertain factors in the formation and they are very complex, each drilling operation has the possibility of blowout, which puts forward higher requirements for well control techno...
T-seals were originally developed to retain the advantages of O-rings in dynamic fluid power applications while addressing two of their most serious reliability problems: (1) squeeze through the gap between static and dynamic surfaces, and (2) Instability in the groove, which leads to failure of the helix or twist. T-seals eliminate both of these problems while retaining the space-saving propertie...
Working Principle and Characteristics of Piston Pump in High Pressure Washer The piston pump moves forward and backward through a fixed seal. The piston pump relies on the reciprocating motion of the piston to make the working volume of the pump chamber change periodically, so as to realize the suction and discharge of liquid. The plunger pump seal is installed on the plunger through a smooth cyli...
If the sealing system on your equipment fails prematurely or cannot work normally, you may immediately check the following points: Whether the seal is defective; Whether the sealing material can not withstand the temperature or pressure requirements of the application; Whether the size is appropriate or the extrusion level is verified; However, the inspection of mating metal components is easy to ...
