Mine explosion-proof solenoid valve
One, overview
Explosion-proof solenoid valve can be matched with various types of automatic spray dust control device for DFB15/10.0 mine, widely used in coal mine underground belt conveyor transfer points, bunker coal and roadway needs of various places of automatic spray dust, the explosion-proof electromagnetic valve is a normally closed structure, the form of joint for G1/2 ′, material, valve and other water contact parts are made of high quality stainless steel, which can meet the coal mine of various types of water use; the structure of the pilot valve structure, with large diameter, small resistance loss, using the characteristics of long service life. DFB15/10.0 mine flameproof electromagnetic valve is used in the environmental temperature of 5 ℃ ~ 40 ℃, the average relative humidity of environment < 95%, explosive mixture but without destroying the insulating gas in coal mine.
