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 the difference between the valve before the pump and the valve after the pump?: Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.

Q: What does the "Z45T-16" valve mean?: Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method

Q: Where is the valve used?: Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water works,

Q: What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?: Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,

Q: Which direction is the valve? Which direction is it?: Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool

Q: There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature: The valve has a device like a cylinder lock that opens with a special key.The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.

Q: What are the general types of valves?: Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve

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.
