After the water pressure in the fire-fighting equipment is consistent with the water pressure in the water valve, the valve core 2 continues to be squeezed downward, and the upper end of the valve core 2 is separated from the valve core cover 4. Figure 7 , the entire valve core is opened, and the water in the valve body 1 enters the fire-fighting equipment through the water intake channel 5. After the water is taken in, the fire-fighting equipment rises and leaves. The first valve 21 rises under the rebound force of the first spring 23, and the valve core 2 returns to its original position under the rebound force of the spring 17, and is sealed against the valve core cover 4. The utility model has a simple structure, and the valve core cover 4 is easy to disassemble and assemble. After the valve core cover 4 is removed, the valve core and the first valve can be taken out. It is easy to disassemble and assemble, and the replacement and maintenance speed is fast and the cost is low.

[0056] The utility model has the advantages of simple structure, convenient valve core taking and placing, fast replacement and maintenance, low use cost, etc. due to the adoption of the structure.
