Q: Z11H/Y forged steel gate valves H/Y what does that mean?SZ45H S what do you mean?Blow 2Z41YGY-40P, what do you think?What does NKZ61H vacuum valve NK mean?What does DS/Z64H water seal valve DS mean?Specific valve number how to see ah, detailed information, thank you!: 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 a lift rod valve?: Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.

Q: Valve category can fill the trunk door, branch valve Mody?: Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric 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: I would like to ask commonly used water valve what kind of? What are the characteristics?: The valve is usually composed of two parts: the actuating mechanism and the valve bodyAccording to the power used by the executing agency, the valve can be divided into four kinds: manual, pneumatic, electric and hydraulic. According to its function and characteristics, it can be divided into on-off valve, regulating valve, electromagnetic valve, electronic type, intelligent type, etc.According to the type of the body: through single seat, through two seater, angular, diaphragm, three links, eccentric rotation, butterfly, sleeve type, spherical and other 10 kinds of; according to the valve body material: cast iron, cast steel, forged steel, carbon steel, stainless steel, copper, plastic valves.

Q: What is a heavy body valve?: To put it plainly is the question of weight... This is to the wall thickness and weight, specifically on what to use

Q: How to carry out the valve strength test and air tightness test?: Refer to the GB/T13927 or ISO5208 standards and need to pass it to you

Q: How do you calculate the flow of the valve?: Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.

Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you: Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.
