Q: What kind of industry does valve belong to?: Valves are machinery and industry equipment；Valve belongs to general mechanical equipment

Q: What does valve J41H-16C mean?: J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel

Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?: Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation

Q: Why is copper used in cryogenic valves?: Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!

Q: What is the valve?: The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.

Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.

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 are the key valve enterprises in China? Mainly in those areas?: The region, the largest number of Wenzhou. Focus on the valve business, Zhongyuan District Kaifeng high pressure valve factory, Zhengzhou Zheng butterfly valve on behalf of the butterfly valve. Shanghai region, Tianjin, northwest Lanzhou high pressure, Suzhou area, northeast Tieling region, Dalian, Shenyang and so on. And the Zigong area

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 valve has a device like a cylinder lock that opens with a special key.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: How are the types of valves classified?: Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
