Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:How about leaking water pipe valve?
What specific circumstances, I teach you repair what valve, how big, which seal leaks
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:How about the quality of FITOK valves?
Purely under the banner of what import, in fact, everyone knows, is the genuine domestic goods.
Q:How to identify a good or bad valve?
You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!
Q:What valve does the high pressure by-pass valve DN254 * 800 belong to?
You want to ask the classification or valve DN254 mean?. The data you gave was incomplete. No answer.
Q:Suddenly no water at home, asked about the property,
You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
Q:How can the valve actuators be classified?
The boring actuator, that is, the pneumatic valve actuator, is described in the customs notesPneumatic valve actuator (three) separately presented. This device is equipped with a piston metal enclosure, linear motion of compressed gas generated by a needle perpendicular to the piston rod into the rotary motion, in order to control plug valve or other device with a rotary deviceSo the Shanghai customs will bring you the list backIn fact, the most important point of distinction or the actuator is pneumatic energy conversion in what form movement of the mechanical energy output, if it is a straight reciprocating, 84123100 is correct, if not belonging to the rotary linear motion, or radians, 841239 correct
Q:How does the valve close?
This is a relatively vague ah, like the stem ah, usable spanner clamping, clockwise rotation in the end. The handle should be closed groove and the coincidence place.
Q:What is a hot melt valve?
For the pillars of the temple are scattered on both sides,I first saw you when I was about to leave.The prey in the net is a star.Far away, where you are nowBecause I love you。For a very Chinese, this ha ha!
