A fire pump from the research and development to the completion of production, is through multiple processes, multiple assessment. In order to remove trapped air from the pipe automatically.

A fire pump from the research and development to the completion of production, is through multiple processes, multiple assessment. Many customers in the purchase of fire pump, only know how to choose the fire pump, choose how much flow of fire pump, or from the surface detection of fire pump is qualified, but I do not know, to understand the new rules in the process of fire pump production.


For 15 years, we have been researching and developing the cast iron fire pump models required by the new and old customers. At the same time as the environmental protection fire pump model itself supply home, beidai technology pump valve co., ltd. has the responsibility and the obligation, will be more high quality multi-stage fire pump model, present to you.

So, bedtech xiaobian on the fire pump valve door and pipe regulations, and we talk about.


Regulation 1: the common fire pump pipe adopts a single valve with manual opening and closing function, but if the fire pump outlet pipe diameter is >300mm, it cannot adopt a single valve with manual opening and closing function. The simple combination of remote control valve has the function of quick opening and closing, and the seal is reliable, and marked with obvious opening and closing mark at the valve

Regulation 2: fire pump normally open or normally closed valve should be equipped with a locking device, control valve and need to open and close the valve should be equipped with an open and close indicator. The opening and closing signal of the control valve participating in the linkage control of the remote control gun system should be sent to the system control room.

Regulation three: fire pump pipeline material is very particular about, in general, fire pump pipeline should choose corrosion resistant materials.

Rule 4: if the fire pump pipe is carrying foam, foam mixture or sea water, the appropriate location of the pipe should be set flushing interface. In order to remove trapped air from the pipe automatically. Or a bypass test interface is provided behind the foam proportioning device.

The valve of the fire pump is the control part of the fluid conveying system, which has the functions of cut-off, regulation, flow diversion, prevention of countercurrent, voltage stabilization, diversion or overflow pressure relief, etc. The pipe of the fire pump is a device for conveying gas, liquid or fluid with solid particles, which is connected by pipes, pipe couplings and valves. The two are inextricably linked, seemingly independent, but have to support each other.
