- Q:Ball valve specifications are represented by 2 FF,
- FF refers to the form of connection between the valve and the pipe lineFF, or Flat Face, is a common form of flat flange connection
- Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
- 3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.
- Q:What does "ball pq340h-10c-1200" mean?
- This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.
- Q:All inclusive ball valve and half a bag of the difference between the ball, mainly new manual ball valve
- In our country, ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electricity, municipal, steel and other industries, and occupy a pivotal position in the national economy. The utility model has the action of rotating 90 degrees, and the cock body is a sphere, and has a round through hole or a passage through its axis.Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve used, V ball valve. Electric valve should pay attention to the pipe parameters, but should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, the use of its state by its use of environmental impact. Under normal conditions, electric ball valves, butterfly valves in the following environmental use should pay special attention to.
- Q:Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no problem with the 10 Water Leakage.Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no Water Leakage problem, while the valve under the same position is fixed and can not rotate, will this situation is normal? Is it possible to leak water in the future?
- Valve handle rotation more times, it is likely to water seepage
- Q:How can the eccentric hemisphere valve be repaired? What are the things you should pay attention to when installing?
- 6, the valve driving device to a fastening bolt before debugging, not allowed to loose. When the valve is used for a long period of time if there is leakage, the driving device limiting fastening bolts loose, counterclockwise rotation of a circle and a locking nut, the valve closed, due to eccentric action to eliminate wear clearance, to ensure that the valve to use, must not be forced to close the valve without release driving device a fastening bolt limit case, this will damage the drive device.7, eccentric semi ball valve is a one-way valve seal, valve seal for the arrow on the body, rather than the medium flow, installation when used as a cut-off valve, and the same medium flow arrow (i.e. being installed), when used as a check valve is used, instead the arrow with the direction of medium (reverse installation).
- Q:What does "all pass" ball valve mean?
- Simply put, from the valve side of the runner hole, put a ball of the same diameter can pass to the other side, that is, all pass ball valve
- Q:What does "2P" ball valve mean?
- The left valve body and the right valve body consist of two parts.
- Q:Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?
- P3, C2? Uncultured, I know P and C, P is the sealing surface material boroning steel is above C, WCB or A105But you Tidianyijian pressure 15MPa, RF surface is not well, the best is to use RJ flange
- Q:Where are the natural gas ball valves produced?
- Do not know, do not know, may be in the area where the factory is TrumanHope to solve your problem.
