Embodiment
The special-purpose Emergeny Cutoff Valves of a kind of oxygen, as shown in Figure 1, the special-purpose Emergeny Cutoff Valves of a kind of oxygen comprises including valve seat 1, valve body 2, control valve valve rod 9, valve top cover 15 that described valve seat 1 is connected with valve body 2 by sealing joint strip, screw; Be provided with flap guide sleeve 3, flap spring 4, flap 5, cylinder sleeve 6 in the valve body 2, flap guide sleeve 3 is arranged at valve body 2 bottoms, and is connected with valve seat 1, and flap guide sleeve 3 the other ends are connected with flap spring 4, and flap spring 4 is connected with flap 5; Flap 5 is provided with cylinder sleeve 6, piston 16, and is connected with control valve flap 8, control valve valve rod 9 by piston 16; Valve body 2 the other ends are connected with valve gap 7, and control valve flap 8, control valve valve rod 9 are arranged in the valve gap 7, and pass valve gap 7 and be connected with pneumatic actuator 14; Pneumatic actuator 14 is arranged in the valve body link 10, and pneumatic actuator 14 is provided with contact 12; Valve gap 7 the other ends are connected with valve body link 10, are connected with valve position switch 11 on the valve body link 10; Valve body link 10 the other ends are connected with valve top cover 15 by valve body cylinder sleeve 13; During use, when valve is opened, gas is from air-inlet cavity 19, gas promotes flap 5 by pressure, is communicated with air-inlet cavity 19 until outlet chamber 18, reaches the purpose of gas transmission, at this moment, control valve flap 8 closely cooperates with valve gap 7 inwalls, and the oxygen that causes entered by suction port 17 this moment can't promote piston 16, and this moment, valve was in opening state; When throttle down, manually promoting pneumatic actuator 14 driven plunger 16 moves downward, this moment, control valve flap 8 broke away from valve gap 7 inwalls, oxygen is entered with the surface of control valve flap 8 by suction port 17 and contacts, the power that produced by gas pressure and control valve flap 8 cross sections this moment is bigger with the power that flap 5 cross sections product is produced than the gas that has air-inlet cavity 19 to enter, cause piston 16 to move downward, until separating outlet chamber 18 and air-inlet cavity 19, reach state of equilibrium at last, this moment, valve was in closed condition.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
