ball valve manufacturer

 Card casing joint water card sleeve joint stainless steel piston o-ring seal sealing water stop, through the oil pressure or water pressure control input and exit the o-ring seal. By changing the oil (or water) in the direction of the control of the o-ring seal movement direction, to meet the needs of the operation.
O-ring seal with the valve body and applied double o-ring seal ball valve manufacturer between the end cover, and can be reduced by setting the PTFE ring way of o-ring wear. Every decca set two o-ring seal sleeve joint, upstream side for overhaul sealed and downstream side seal for work. Overhaul sealed a manual locking device, and normal work overhaul sealed in a normally open state, only during overhaul, input, in order to ensure the maintenance of Ann - downstream All sex, should be manual will lock into. Work sealed into the ferrule joint closed, exit before the ball movement. For the warranty card set of joint can close quickly in an emergency, the brass pipe joint after reaching full open, seal is still in the work out of shape State.
The groove pipe fittings to solve noise method is as follows:
1, when impacted by external force, displacement happens between each other, form the three-dimensional deformation, fitting will not be affected, avoid mutual friction between pipe fittings, can effectively reduce the noise.
2, the groove pipe internal installation of sealing ring can absorb part of the external force when building a hit, to prevent the pipe because of external forces under overweight cause pipe deformation, affect the appearance of 14 needle valve the overall performance, shock resistance, effectively reduce the noise There is. Brass adapter to avoid vibration, leakage, thermal shock, serious and cause huge loss resulting from improper installation problem to provide reliable, prevent leak sealing connection.
Brass connector Prevent leak sealing performance, install on the good quality of card sleeve, even in poor working conditions of brass connector will not leak. This is because, this kind of brass joint depends on the metal to metal mechanical seal. Through the tight coupling nut can be put Card sets of cold extrusion on the card sleeve.
Brass joint always detectable. After installation of preliminary, using gap detection rules can make the installation personnel or inspectors to ensure that the card sleeve joint is fully tighten. If the nut has been properly tightened, so test gauge can't into the nut hexagonal end with.
The joint between ontology. Simple installation and consistent initial installation testing can be greatly reduced the installation errors.
The valve is mainly composed of live body, sealing ring, o-ring, screw, a pin, etc. Sealing ring through a set of screws in a living body parts accordingly. Seal with live door to guarantee by o-ring. The role of the locating pin is sealing ring and live.
Door of accurate positioning, in order to avoid sealing ring assembly with live body dislocation after replacement. Sealing ring material is usually 2 cr13. Because of the o-ring seal water turbine inlet card set of joints are normally used for water quality is poorer, high water head of the power plant, so the bad working condition of the card set of coupling loss is very serious, especially 38 needle valve for sealing surface wear very much.
In order to improve the brass pipe joint Maintainability, card sets of joint water card sleeve joint will card set of joint sealing ring design for removable replaceable structure, long-term use of valve sealing ring in the set of joint after serious wear and tear, but only the sealing ring for replacement without the need to change the valve or the other Purchase sleeve joint, improve the service life of the card sets of joint main body, reduce the capital investment.
