Intelligent fire valve

Abstract

The invention relates to the technical field of fire-valves, in particular to an intelligent fire valve. The intelligent fire valve comprises a valve body; a straight pipe section and a bent pipe section are arranged on one side of the valve body; a cavity is formed in the valve body; a blocking plate section is arranged in the cavity; the section of the blocking plate section is trapezoidal; a passing opening is formed in the blocking plate section in a penetrating mode; a threaded hole communicated with the interior is formed in the upper end face of the valve body; a threaded rod is arranged in the threaded hole in a matched mode; a rotating handle is fixedly arranged at the upper end of the threaded rod in a sleeved mode; a circular through hole is vertically formed in the threaded rod; two abutting columns are arranged in the circular through hole in a sliding mode; circular grooves are formed in the end faces, close to each other, of the two abutting columns; a limiting spring is vertically arranged in the circular through hole; and a thermosensitive limiting structure for limiting the abutting column on the upper side is arranged at the upper end of the threaded rod. The intelligent fire valve can be used for a fire valve, has the function of automatically opening to extinguish fire in case of a fire, has a relatively high fire extinguishing effect, has a relatively high resistance effect on a water hammer and a negative water hammer, and is relatively long in overall service life.

Description

technical field [0001] The invention relates to the technical field of fire-fighting valves, in particular to an intelligent fire-fighting valve. Background technique [0002] At present, the widely used fire valves are basically manual or electric valves. Manual valves require manual manipulation, and electric valves require electrical control to open the valve. Manual opening is easy to cause damage to personal safety, and at the same time, the fire cannot be controlled in time, while the electric valve is easy to be damaged; water hammer refers to the inside of the water pipe, the inner wall of the pipe is smooth, and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve. Due to the smooth wall of the pipe, the subsequent water flow quickly reaches the maximum under the action of inertia and produces destructive effects. However, the fire water pressure is relatively high,...

Problems solved by technology

[0005] This solution automatically triggers water sprinkler fire extinguishing, but the simple water spray fire extinguishment is not effective in dealing with some strong fire situations. At the same time, the memory metal of this solution is not easy to replace, and this solution does not solve the problem of water hammer when the valve is closed. , resulting in a shorter service life
