The Daily Maintenance Of The Fire Hydrant Valves And The Normal Use

Fire hydrant system is the main fire fighting facilities adopted in China, and the decompression and water supply zone of the fire hydrant system is the technical problem of the fire hydrant system which is often encountered in engineering design. On the commonly used fire hydrant system decompression method: reduced pressure orifice decompression, throttle decompression, decompression valve decompression, decompression tank decompression made an introduction. At the same time, it introduces the tendency of diversification of decompression methods, and introduces the decompression and pressure fire hydrant and decompression and pressure relief (fire), and its pressure on the specification.Fire Hydrant Valves

Need to calculate, increase the design workload. Different pipe section, the required decompression value is different, so larvae L diameter is not the same, easy to install when the wrong, thus affecting the decompression effect. Fire water supply system there are a variety of water supply, a variety of water supply conditions, such as: fire tank water supply, fire water pump, fire pump water supply, fire engines, such as water supply. The current fire regulations stipulate the water pressure of the fire hydrant, and in the engineering design, according to the calculation of the fire pump water supply calculation, but also by the fire pump to determine the water supply calculation, but also by other water supply, water supply conditions to calculate definite.Fire Hydrant Valves

It is difficult to determine the outlet pressure of the fire hydrant when the fire hydrant is directly connected from the horizontal horizontal pipe network in the room. Therefore, it is difficult to calculate the orifice diameter of the reduced pressure orifice plate.

Routine maintenance management for the normal use of water supply valve group to ensure the normal operation of the water supply system is essential, should be included in the property management department of the daily maintenance and management of the work content, the development of appropriate maintenance management system and pressure relief valve operation data record form, Effective implementation; local water supply enterprises and water supply departments should be subject to supervision and inspection, if necessary, spot checks on the operation of the valve, check the daily inspection and maintenance of data records.Fire Hydrant Valves
