Design Standard:

Q: What does the "XV" valve mean?: XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.

Q: For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: The opening moment (torque) is the force or torque that must be applied when the valve is opened or closed. Need to open and close the valve when the sealing pressure than the formation of closed and valve seat sealing surface between the two, but also to overcome between the stem and the packing between screw stem and the nut, the valve stem friction end bearing and other friction parts. Therefore, certain closing force and closing torque must be applied, and the required opening and closing force and opening and closing torque during the valve opening process are varied, in which the maximum value is at the closing instant or the initial opening moment. Design and manufacture of valves, should strive to reduce the opening and closing force and opening and closing torque.The open torque can be obtained by means of calculation or measurement, and can be obtained by hand torque measurement.

Q: Where is the filling portion of the valve?: The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.

Q: Is there any problem with connecting the geothermal valves with other geothermal pipes?: Can be universal,Material is the same, the fuse will not cause shrinkage when you can use

Q: What are the technical requirements of valves, such as "Z15W-25T"?: Z = gate valve1 = internal thread connection5 = dark rod type (structural form)W = body seal payments25 = 2.5MPa (nominal pressure)T = copper (body material)Landlord can refer to JB/T 308-2004 valve model preparation methods

Q: What do you mean by the 16 bit coding of the valve type?: Not regular encoding. Regular encoding is usually 11 bit and sometimes 13-14 bit

Q: What is the flow medium of the valve?: Just like the one in your bottle, then the medium in your bottle is water

Q: What are the ten major brands of China's valves?: 1. fine fine group valve Co., Ltd.2. Zhuzhou Southern valve Limited by Share Ltd3 Chinese KaiWeiXi valve group4 the Sufa technology industry Limited by Share Ltd5 Zhejiang Chaoda valve Limited by Share Ltd6. Sichuan Zigong high pressure valve Limited by Share Ltd7. 、 Shanghai Valve Manufacturing Co., Ltd.8. Guangdong Mingzhu group Limited by Share Ltd9. three flower holding group10 Shanghai Valve Factory Co., Ltd.

Q: What is the term "Z41H-16C" on the line?: Therefore, the opening position of the valve is determined by the position of the gate (i.e. the stroke).Z41H-16C closed, the sealing surface can only rely on medium pressure to seal, that is, only rely on the media pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

Q: How can the material be checked by valve approach? What experiments do you need?: First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
