In the side of gas cleaning system air inlet pipe, including gas outlet, lose heart pipe flange, elbow bend, elbow flange A, elbow flange
B, valve body short tube, valve body short tube flange, explosion venting valve, pedal, wherein described gas outlet is horizontally disposed, and its one end is entered with described
Trachea is connected, and the other end is connected with disappointing pipe flange, and the elbow bend two ends are connected to elbow flange A, elbow flange
B, elbow flange A are made the other end of elbow bend straight up, and are passed through elbow flange B by the disappointing pipe flange of screw rod connection
It is connected with the valve body short tube flange, the valve body short tube lower end is connected with valve body short tube flange, upper end and described explosion venting valve
Connection；One end of the gas outlet connection elbow bend is provided with pedal, and pedal one end is connected to gas outlet one by diagonal brace muscle
Side, the other end are extended to below gas outlet, and connect the opposite side of gas outlet by vertical connecting rod, and the pedal is by two pieces of sides
Plate and the iron plate composition being disposed between two blocks of side plates, iron plate two ends are by rivet interlacement on described side plate.
As a kind of further improvement of gas piping pressure relief device of this utility model：The diagonal brace muscle of the pedal and connection
Bar is welded on gas outlet.
As a kind of further improvement of gas piping pressure relief device of this utility model：The elbow bend diameter is less than and lets out
Tracheal diameter.
Beneficial effect
A kind of gas piping pressure relief device described in the utility model, gas outlet are connected to the aerofluxuss that is drawn by either inside
Between pipe and electrostatic precipitator.Gas outlet one end connects exhaust main, and the disappointing pipe flange of other end connection, the setting of flange make
Obtain and closely connect between each connector.The disappointing pipe flange of elbow flange one end connection, the other end is arranged straight up, and and valve body
Short tube flange is connected, different from the horizontal mounting means of conventional explosion venting valve, and this utility model introduces elbow bend makes explosion venting valve vertical
Install upwards so that inside explosion venting valve, near venting of dust explosion film, be difficult hydrops, extend the service life of venting of dust explosion film.Valve body upper end of short tube
Explosion venting valve is connected by flange, valve body short tube lower end connection valve body short pipe method is blue.The setting of valve body short tube increased explosion venting valve with
The distance of elbow, it is to avoid in the pressurized uneven caused rupture of elbow venting of dust explosion film.The one of gas outlet connection elbow bend
End is provided with pedal, and pedal one end is connected to gas outlet side by diagonal brace muscle, and the other end is extended to below gas outlet, and is passed through
Vertically connecting rod connects the opposite side of gas outlet, and the pedal is by two blocks of side plates and the ferrum being disposed between two blocks of side plates
Plate is constituted, and iron plate two ends are by rivet interlacement on described side plate.As gas outlet is needed installed in higher position outside workshop,
So in order to easy to installation and maintenance, below explosion venting valve, lose heart pipeline and elbow junction setting pedal, is easy to service worker
Maintenance.Pedal plane is made up of a plurality of iron plate, it is to avoid plane hydrops, accumulated snow bring inconvenience to maintenance.
