Q:What is the purpose of the valve?
6. Indicate and adjust the level of the liquid. Such as liquid level indicator, liquid level regulator, etc..7, other special uses. Such as temperature control valve, over-current protection, emergency shut-off valve and so on. In the above valves, the valve used to connect and cut off the medium flow in the pipeline, the use of the total number of about 80% of the total number of valves.
Q:What are the ten major brands of China's valves?
Tianjin Gangyan guangheng special equipment Limited by Share Ltd is the leader Chinese special material valve industry, a joint venture with Chinese Gangyan established
Q:What is the normal temperature on the valve?
What's the valve?. Conventional valves are 425 degreesIf it's on the oil field. It's only 120 degreesAt normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
Valve international universal caliber national nominal diameter1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
Q:What is the difference between a stop valve (a power station valve) and other valves?
The cut-off valve is low in and out of the structure, usually used in the case of pressure loss, the cut-off valve is not through the form. Gate valve is straight through type.
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:What does the "Z45T-16" valve mean?
Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method
Q:How to carry out the valve strength test and air tightness test?
Refer to the GB/T13927 or ISO5208 standards and need to pass it to you
Q:How to suppress the valve?
Valve pressure is generally divided into 2 parts. One is shell pressure test, one is sealing test pressureShell pressure test is 1.5 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the shell test pressure will reach 24 pressureThe pressure on the seal is 1.1 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the pressure test on the seal will reach 17.6 pressure. That's all right.
Q:What is the valve before and after the pump?
Conventional setting, the pump is installed before and after the cut-off valve. As for the check valve, according to the need to decide whether to install, to see whether the occasion required to prevent backwater function.
