- Q:What's the difference between valves and valves without valves?
- In that regard, some valves are one-way valves, only out of the can
- Q:What is called protective valve, and other valves what is the difference?
- Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.
- Q:How to carry out the valve strength test and air tightness test?
- All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed
- Q:Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
- At the intersection of Mingguang Road and Shengli Road, the southwest side is all made of valves

- Q:The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This is the same as the second, pull out half or all, so that you can use gas, ha ha!
- Q:Standard and specification for pressure test of valves
- (11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.
- Q:What does the whole copper valve mean?
- Industrial oxygen pipes on the valve are all copper valve, hand wheel is not. The market had had 4 6 1 inch screw valve also has a lot of full copper. The tap also has all brass. The valve body and the inside are all copper.
- Q:What do you mean by "P54" in the valve z962y-p54 100V?
- Applicable temperature 540 degrees centigrade;Applicable temperature 540 degrees centigrade
