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.s
How to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..s
Several problems about valve parameters
FV: flow control valveLV: level control valveCV: flow coefficient flow coefficient CvFlow coefficient of an imperial unit. Is equal to the temperature of 40 degrees Fahrenheit Fahrenheit water in -100 1psi (6894.8Pa) 1min flows through the valve pressure drop US gallonThe domestic habits called Kv, Kv said that the valve flow capacity, it is defined as: when the control valve fully open, the valve pressure difference at both ends of a P 100KPa, R 1gf/cm3 (severe fluid that is often warm), per hour through the number of flow control valves, with m3/h or t/h.Cv=1.167Kvs
How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
For you to introduce the spreadsheet calculation, application basis, you according to this principle for valve correlation calculation:When A1 and B1 cells are used as parameters, the amount of computation is calculated by C1. If the formula is X+Y=? In the A1 cell, fill in the X; fill the Y in the B1 cell; fill in the C1 cell with "=A1+B1"; enter the carriage, and then calculate the corresponding value in the C1 cell. For example: fill in 5 in the A1 cell; fill in 8 in the B1 cell; enter the carriage, and then appear in the C1 cell 13. Other calculations are the same, you will calculate the valve formula, such as the above fill in, given the corresponding parameters, the same can be calculated.s
