Q:What is the term "Z41H-16C" on the line?: When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.

Q:How does the valve rust die?: The treatment of valve rust is as follows:1, use corner grinder cut off valve, and then a small mill grinding wheel cutting residual film cut pipe installed in the screw part, when the attention of cutting depth.2, with the amount of hydrochloric acid corrosion and rust of the valve, until the rust completely removed, rinse with water.3, on the newly purchased valve galvanized, can effectively prevent rust.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. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.

Q:The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?: Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.

Q:What should be checked before using the valve?: The valve must be visually checked before installation1, valve opening and closing position should meet the following requirementsThe valve, the cut-off valve, throttle valve, regulating valve, butterfly valve, foot valve, the valve is in full closed positionPlug valves and ball valves should be in full open position? diaphragm valve should be in the closed position, and can not be too tight to prevent damage to the diaphragmCheck valves shall be closed and secured2, the valve shall not be damaged, missing parts, corrosion, nameplate shedding and other phenomena, and the valve body shall not be dirty3, both ends of the valve should be protected. Handle or handwheel should be flexible and light, and must not be stuck4, valve body casting, the surface should be smooth, no cracks, blisters, lock, pores, burrs and other defects; outside valve forging, the surface should be free of cracks, interlayer, double skin, scar defect

Q:What is the KVS in the valve parameter?: The Kvs of the valve reflects the passing capacity of the valve

Q:What does 1/2 mean in valve specification?: 1/2 inches mean, converted to metric unit is 15mm, belong to small caliber, if the valve specifications, that is, the pipe diameter is 15

Q:What is the difference between valve j941H-40 and j41H-40?: Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one

Human valves have been used for nearly 4000 years. In ancient China from the brine well absorb salt brine, once in a bamboo pipe used in cork valve. In the 1800 BC, the ancient Egyptians used similar wooden cocks to control the distribution of water to build large water conservancy projects to prevent the Nile from overflowing. These are the embryonic form of the valve. The extensive use of industrial valves began only after Watt invented the steam engine. In the early twentieth Century, there were valves of cast steel, wrought steel and forged welded joints.

Q:How big valves are used in the DN90 pipeline?: If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding
