Q:Hydrant valve leaks, how do you close other valves? Specific steps?
Hello my name is Baidu know the long days of high water leakIn the vicinity of a common fire hydrant, there is a valve, which is convenient for fire hydrant maintenance, because fire hydrant repairs need to close the water source. Look around, it should be easy to find the valve. Switch valve is very simple, and the direction of the twist screw is the same, clockwise turn off, counterclockwise is open. Closed valve, fire hydrant will not leak, you can feel relieved to repair. I guess your fire hydrant is sealed rubber pad, aging causes leakage, it is a common disease of fire hydrants.
Q:Pump, valve, these belong to the material?
Pumps, valves are electromechanical equipment, belonging to a class of hardware fittings, but not material!
Q:Which brand of electric valve is good?
The electric actuator imports now commonly used with Omar, Rotok, SIEMENS, you should still work to decide which Denso, such as regulating type? Switch mode? Intelligent? Regular type? There are valves can choose some well-known brands
Q:What's the material of j41h-16p's valve?
Stop valve characteristics:(1) the structure is simpler than the gate valve, and the manufacture and maintenance are more convenient.(2) the sealing surface is not easy to wear and scrape, good sealing, when opening and closing, there is no relative sliding between the valve and the sealing surface of the valve body, so the abrasion and abrasion are not serious, the sealing performance is good, and the service life is long.(3) when opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the structure length is longer than the gate valve.(4) the opening and closing moment is big and the opening and closing are more strenuous.(5) large fluid resistance, due to the valve in the medium channel is tortuous, large fluid resistance, power consumption.(6) the flow direction of medium nominal pressure PN is less than or equal to 16MPa, commonly used downstream, medium from the valve under the direction of flow; nominal pressure PN = 20MPa, using reflux, medium from the valve on the downstream direction to increase the seal. When used, the cut-off valve medium can only flow in one direction, can not change the direction of flow.(7) when fully open, the disc is always subject to erosion.
Q:The difference between fire general valve and fire fighting special valve
Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.
Q:What does the whole copper valve mean?
Except the handwheel, all the material of the valve body is copper
Q:Is the filter also valve?
The filter is in fact a low inlet and outlet shut-off valve with no disc and valve head. The filter screen is arranged in the middle, to control the filter according to the number of travel impurities. Usually follow the valve to tender, but not valves.
Q:What valve is the FCV?
FCV, control valve - you can adjust the valve opening according to the required flow
Q:Heating pipes, in addition to the living room,
It is loaded against the supply and return water pipe is not underground do in next time if it is to see if there is any water on the side of the baffle remember from the baffle recently if it is normal that is motivated next must put off the baffle
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
