Bucket is pierced by putting hole.
The fire arrester includes back-fire relief section and fillter section, and back-fire relief section is connected to escape pipe, and fillter section is connected to air inlet pipe, filtering
Flue-dust retainer is arranged in section bottom, and fillter section includes shell, and shell is interior to be respectively set deflection cone and filter screen, water conservancy diversion from air inlet to outlet
Cone and filter screen are respectively engaged on support short slab, and support short slab is immobilized in the shell wall, and valve is arranged between flue-dust retainer and shell
Discharge lid is arranged in door, flue-dust retainer bottom.Gas enters in fillter section under the shunting function of deflection cone by air inlet, passes through
Fillter section medium wave schlieren filter net carries out the filtering of gas, and back-fire relief effect is good, and filtered gas enters outlet by back-fire relief section
In pipe.Flue-dust retainer collects dust, prevents from blocking.
The back-fire relief section is set as tubular construction.
Valve member cabinet does encapsulation process in the junction with air inlet pipe, escape pipe, flue-dust retainer, guarantees valve member cabinet internal pressure
The normal monitoring of power.Gaseous-pressure sensor can detecte the pressure of the fuel gas in pipeline, and this signal is exported to outer
The controller enclosed, when having combustible gas leakage when the pressure of fuel gas is abnormal or between each components, the above signal meeting
Be transmitted to peripheral controllers, controller can according to the on-off of control process control natural gas, if there is the leakage of fuel gas,
Air has been reserved on gas valve member unit or the gas of inert gas is filled with mouth and gas flow outlet, can make compressed air or lazy
Property gas enters in valve member cabinet, and fuel gas is drained.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, be easy production, maintain easily, it is ensured that system safety operation, reduce production and
Operating cost brings benefit to enterprise.
