Problems solved by technology
[0004] The high-speed switching valves used in the current coal mine gas active flame retardant, explosion suppression and fire prevention systems are generally driven by electric motors, with relatively small calibers, low sealing reliability, and slow response time. The response time is about 10ms.

Embodiment Construction
[0036] Such as figure 1 Shown, be fire-fighting electric explosion valve of the present invention, mainly by housing 1, spool 2, compression nut 3, piston 4, lock nut 5, nut 6, electric explosion tube 7 and O-shaped rubber sealing ring components. The electric explosion valve has simple and reliable structure, high response speed, good sealing performance and safety. In addition, the processing and assembly process is good, and it is suitable for mass production.
[0037] The electric explosion valve adopts a redundant design scheme driven by double electric explosion tubes. The double electric explosion tubes are arranged radially and symmetrically to ensure uniform pressure distribution in the explosion pressure chamber and improve the reliability of the electric explosion start of the valve. The cut-off part of the spool adopts the bushing pull-off structure design. After it is installed in the shell, the left end is pressed with a compression nut, and then the piston is ...

The invention relates to a key control assembly, namely a high-pressure large-diameter mining firefighting electric explosion valve suitable for a coal mine firefighting and gas explosion suppression system and other various firefighting systems. The high-pressure large-diameter mining firefighting electric explosion valve is composed of a shell, a valve element, a pressing nut, a piston, a locking nut, a screw cap, an electric explosion tube and the like. The mining firefighting electric explosion valve has a large diameter (DN40), and is high in starting response speed with the response time of about 5 ms, high in reliability, capable of meeting long term of pressurized storage (PN10.0 MPa) and high in safety. Meanwhile, the product is simple in structure, good in machining and assembly manufacturability and suitable for batched production. The mining firefighting electric explosion valve can be used for the coal mine firefighting and gas explosion suppression system and other various firefighting systems.
Description
technical field [0001] The invention relates to a high-pressure large-diameter fire-fighting electric explosion valve suitable for coal mine fire-fighting, gas explosion suppression systems and other various fire-fighting systems. Ensure that the fire suppression system works at critical moments. Background technique [0002] Gas has become the number one killer threatening the safety of coal mines. The vast majority of major accidents in coal mines are gas accidents. The key to gas prevention and control work is the level of technical equipment and the resulting ability to prevent and resist disasters. At present, the gas active flame-retardant and explosion-suppression fire prevention system has become an advanced means of preventing and controlling gas disasters, and will gradually replace the passive flame-proof system commonly used in coal mines in China. [0003] Mine fire-fighting electric explosion valve is a product developed for the mine fire-fighting and explosio...
