Q:HH valve company in the United Kingdom, how about the valve?
Our factory boiler has this brand of valve, used for many years, has been no problem, really good.
Q:How many valve enterprises in China's valve industry?
How much? I don't know. It depends on what valve you need. Hebei iron and steel Wenzhou, needle valve Funing, Anhui Tongdou valve. Do not want to buy a high price of Shanghai valve, look at your specific needs
Q:How do you see the valve number?
Structure of code structure of code seal vertical plate type single eccentric sealing type 0 single eccentric center 5 vertical plate 1 6 2 7 three double eccentric double eccentric eccentric 3 three eccentric 7 linkage 4 linkage 9 structure of code structure of code lifting straight through 1 swing single type 4 vertical more than and 2 petal angle 5 type 3 dual valve type 6 butterfly valve 7 Table 9 check valve structure of code the sealing surface and lining material code, in accordance with the provisions of table 10. Table 10 the sealing surface of the valve seat sealing surface or liner material code or liner material code sealing surface or lining material code or code of lining material tin based bearing alloy seal (Babbitt) B Monel M alloy T enamel C nylon plastic rubber X N steel boriding nitriding steel D P hard alloy Y fluorine plastic lining F lead Q ceramic G austenitic stainless steel R Cr13 stainless steel H S note: the plastic body directly processed seat sealing surface material code with "W". When the sealing surface of the sealing material is not the same, the material name is indicated by the material with low hardness. The value of the nominal pressure of 10 times, according to the number of MPa (1MPa=106Pa). The valve body material code represented by the letter, in accordance with the provisions of table 11. Table 11 the valve body material body material material code code code C chromium nickel molybdenum stainless steel R Cr13 stainless steel H S plastic steel chromium molybdenum copper and copper alloy I T malleable cast iron titanium and titanium alloys K A L Aluminum Alloy CrMoV V Cr Ni stainless steel P Z gray cast iron ductile iron Q. In the original standard of nominal pressure equal to or less than 1.6MPa gray cast iron and the nominal pressure is greater than or equal to 2.5MPa carbon steel valve omitted the code.
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:Is there a one-piece, two linkage valve?
In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
Q:How do you calculate the pressure difference between the front and rear of the valve?
the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Yes, as long as it's all PPR's.Material is the same, the fuse will not cause shrinkage when you can use
Q:Can the angle valve of York central air conditioner be replaced by other valves?
Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
Q:What does valve A335P22 mean?
May be non-standard label bar, do not understand, A3 should refer to the body, the material is 13Cr.
Q:What does the "XV" valve mean?
XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.
