An intrinsically safe high-pressure fire hydrant

Abstract

The invention discloses an intrinsic safety type high-pressure fire hydrant comprising a valve, a valve rod and a valve base arranged at the bottom of the valve. A water inlet is arranged at the bottom of the valve, a water outlet is arranged on the side wall of the valve, the water inlet penetrates the valve base to be communicated with the inside of the valve, and the water inlet directly faces the valve rod and moves back and forth along the water inlet direction; a concave limit groove is arranged in the inner wall of the valve, a spiral groove is arranged in the outer wall of the valve rod, a limit device is arranged between the valve and the valve rod, one end of the limit device abuts against the limit groove, and the other end of the limit device is slidably fixed in the spiral groove. The intrinsic safety type high-pressure fire hydrant has the advantages that the intrinsic safety type high-pressure fire hydrant is simple in structure, convenient to install and maintain, resistant to high pressure, long in service life and low in equipment cost, and water pressure in the fire hydrant can be monitored in real time through a water pressure sensor.

Description

technical field [0001] The invention relates to fire fighting equipment, in particular to an intrinsically safe high-pressure fire hydrant. Background technique [0002] Fire hydrants are mainly used to provide water sources for fire fighting. For large places such as high-rise buildings and garages, the fire safety requirements are strict, and the fire water pressure is particularly high. [0003] The existing fire hydrant structure is usually prone to pop-up or breakage of the valve stem under high water pressure, resulting in a large amount of water loss from the fire hydrant, wasting water. In order to prevent the fire water from dispersing, people often turn off the fire water source. If it is not repaired in time, there will be great safety hazards in the fire protection system, and it is difficult to maintain the fire hydrant. Maintenance personnel usually replace the entire fire hydrant, which is expensive for equipment and investment. big. Contents of the inventi...

[0003] Existing fire hydrant structures are usually prone to pop-up or breakage of the valve stem under high water pressure, resulting in a large amount of water loss from the fire hydrant, wasting water resources

In order to prevent the fire water from dispersing, people often turn off the fire water source. If it is not repaired in time, there will be great safety hazards in the fire protection system, and it is difficult to maintain the fire hydrant. Maintenance personnel usually replace the entire fire hydrant, which is expensive for equipment and investment. Big
