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: the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?: From the literal explanation, the strong counterpart connection is different from the normal connection. Valves are naturally connected to pipes or equipment, including threaded connections, flanged connections, clamp connections, welding, butterfly valves, clamp connections, etc..Strong mouth connection, similar to the butterfly valve on the clip connection, just outside of clamping method used in other valves (not seen on the clip connection with other valves), so this will depend on external interface of the valve (wafer type butterfly valve, said strong counterparts except).

Q: What does the 4 point valve mean?: The caliber is DN15's valve. What valves do you need?

Q: What is the difference between the valve before the pump and the valve after the pump?: Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.

Q: What courses in the University involve valves?: Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.

Q: How much is the 150LB of the valve?: 150Lb=2.0MPa=20 kg.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.

Q: What are the ten major brands of China's valves?: If you want to buy fluorine valve, you can go to Shanghai corrosion-resistant valve group Co., Ltd., and what questions contact me?!

Q: There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature: The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.

Q: Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.: The pipe you choose is outside the 60 bar D60 pipe DN50 valve is right, such as D89 pipe with DN80, you are outside diameter and nominal diameter concept is not clear

Q: Name: valve actuatorFunction: control valve switch by controlling air flow sizeIntended classification commodity code: 8412310090 (other linear acting pneumatic power unit, pressure cylinder)Shanghai Pudong Airport customs change classification: 84123900 (other pneumatic power unit)Commodity code information given by China Customs official network: 8412310090 (actuator, valve parts, valve actuation, pneumatic)Our goods encoding 8412310090 is classified to the Shanghai Pudong Airport customs dismissed, there are no friends of this commodity encoding on the official website of the detailed specifications defined, I Secretary in accordance with the valve function into 8412310090 encoding. Thank you: 84798990 straight stroke valve actuator84798990 angle stroke valve actuator84798990.90 all intelligent electric valve actuator84818010 valve actuator84819010 valve actuator85371090 electric valve actuatorFor the past 3 years, the shipment code, but not the same as yours, for reference
