Abstract
The invention relates to a mining explosion-proof type electromagnetic valve. A water inlet water guide hole (42) is formed in a water inlet cavity of a lower valve seat (4) and leads to a stepped hole (144). A central column (13) with a hole is arranged at a central water channel (145) of the stepped hole. A water outlet water guide hole (43) is formed in a water outlet cavity (44) of the lower valve seat (4) and is communicated with the central water channel. A sealing film pad (18) and a film pad gasket (3) thereof are arranged in a main valve cavity, and the film pad gasket is in seal fit with a seal ring (2). A sealing pad (7) at one end of a valve core (8) in an electromagnetic valve (11) is in seal fit with the central column (13). The mining explosion-proof type electromagnetic valve has the advantages that by virtue of the equal water pressures of two sides of the sealing film pad and the pressure of a spring, the valve is automatically closed. During energization, the valve core (8) is separated from the central column, and the water pressure below the sealing film pad is greater than that over the sealing film pad to enable the sealing film pad to be automatically opened. Therefore, the mining explosion-proof type electromagnetic valve has the advantages of sensitivity in control, small driving current and durability in use.
