Q: Where is the hydrant main valve?: The intake valve of the upper and lower ring pipes of the riser of the fire hydrant is generally located at the highest and lowest floors.The general use of the valve rod flange gate valve.Hydrants, officially called fire hydrants, are a type of fixed fire fighting facilities, which control fuel, insulate fire and eliminate fire. Indoor fire hydrant and outdoor hydrant. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on. Fire hydrant mainly for fire engines from the municipal water supply network or outdoor fire water network to implement fire fighting, can also be directly connected to the hose, water gun fire extinguishing. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.

Q: What are the specifications of the valves PN25, DN50?: PN25 - nominal pressure 25bar (25kgf/cm -)DN50 - nominal diameter is 50mm (2)

Q: What valve is the FCV?: FCV, control valve - you can adjust the valve opening according to the required flow

Q: Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.: 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=1.167Kv

Q: HH valve company in the United Kingdom, how about the valve?: Our factory boiler has this brand of valve, used for many years, has been no problem, really good.

Q: How to check if the gas valve is open?: Method 1: gas valve has a handle, the handle is parallel to the pipe, that is open, vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the handle is parallel to the pipe, that is, the open state, vertical is closed.Method two: the valve handle and pipe to "one" word proved to come, into "ten" word is off. Also, turn the handle clockwise and turn counterclockwise.

Q: What is the purpose of the valve?: 3. Change the direction of the medium flow in the pipeline. Such as the distribution of valves, three way cock, three or four ball valve etc..4, stop the medium back flow in the pipeline. A variety of different structures such as check valve, valve etc..5, separation medium. Such as different structures of steam traps, air traps and so on.

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 are the types of valves classified?: 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.
