1.Bem-vindo à Shandong Maiwei Fire Technology

2.Composition:

Underground type fire hydrant is a kind of outdoor fire supply facility.

It is mounted underground to avoid causing impact on landscape and traffic.

The hydrant is composed of interface, valve lever, body, flanged pipe, drain valve, valve flap, valve base, valve body, bent pipe, as well as other components.

3.Advantage:

1>It is based on the ordinary bolt and the key parts are improved to make it more practical.

The closed spring outlet is used in the structure, and the positive pressure seal is realized.

2>Switch quickly. Turn the wrench completely off and open for only 4/5 weeks

3> Voltage regulation function. Because of the pressure of fire water, the internal decompression device is opened in sections, one part of the water goes up through the decompression device, and then the other section is opened after a period of time, thus achieving the decompression effect.

4>Anti-freezing function. The stainless steel automatic drain valve is installed below the frozen soil layer (according to the depth of the frozen soil layer in different areas of use, the depth of the automatic drain valve is also changed accordingly).

The hydrant can automatically remove the residual water in the cavity when it is closed.

Prevent equipment from freezing. At the same time, it also saves the setting of gate valve well and gate valve in front of ordinary hydrant pipe, which not only saves investment, but also saves the later maintenance cost.
