Q: What's the valve specification DN20?: It's not clear what you want to ask

Q: How to find all kinds of mysterious valves of human body?: Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.

Q: What is the main function of the valve?: Valve 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 use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?: Refers to the installation of the interface dislocation, misalignment or installation of the wrong size and forced connection, resulting in installation stress exists, in use, it is prone to abnormal damage.

Q: How about leaking water pipe valve?: It depends on where the place is leaking.1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.

Q: What does the valve specification "3/4CL150" mean?: 3/4 is the caliber, that is, DN20, CL150 is the pound, American Standard, and Kg is 16-20Kg.

Q: What does the RF of the valve mean?: The flange flange can be applied to the HG/T flange standard, or any other flange standard. HG/T will be more detailed

Q: What do you mean by the 16 bit coding of the valve type?: What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one

Q: What valve is the YQZ45X-16Q?: Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.

Q: How big valves are used in a DN159 pipe?: DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.
