Background technology
Heating furnace is fuel with industrial gas, by the burning acquisition heat of burner.If can not in time open a realization gravity-flow ventilation of blowing in soon when fan trouble, stove will stop working, and can cause technologic significant problem, and a large amount of methane accumulation has the possibility of blasting.As a kind of emergency set, when blower fan normally moved, a palpus that blows in soon was in good sealing state, then opened gravity-flow ventilation during fan trouble rapidly.Therefore, excellent sealing performance is the basic demand of door of blowing in soon with opening reliably.
Referring to Fig. 1, the pneumatic door that blows in soon of tradition pivoted arm mainly comprises door closure 2 and valve box 1, door closure 2 drives by the cylinder 7 on valve box 1 framework, because cylinder 7 is connected with door closure 2 by crank mechanism, therefore need cylinder 7 vertically to be arranged on valve box 1 framework, this just makes valve box 1 framework need higher height, is used for installing cylinder, caused valve box casing heaviness very, all inconvenience of ten minutes during the installation and removal maintenance.Therefore be necessary to make improvements.
Summary of the invention
At the deficiencies in the prior art, provide a kind of two-door pivoted arm the pneumatic door that blows in soon, can when realizing the convenient unlatching of door closure, not need very high valve box box height.
The utility model is achieved through the following technical solutions: the pneumatic door that blows in soon of two-door pivoted arm, comprise valve box and door closure, described valve box is provided with mount pad, in described mount pad, rotate and be provided with rotating shaft, be provided with rocking arm in described rotating shaft rotation, rotate on the sidewall of described valve box and be provided with cylinder, the cylinder fork is fixedly arranged on the piston rod of described cylinder, described rocking arm and described cylinder fork are rotationally connected, exerting oneself by cylinder drives rotating shaft and rotates, and described door closure is fixedly connected in described rotating shaft.
In the technique scheme, described mount pad comprises mounting seat and erection support, at described erection support inner fixed bearing, described rotating shaft is set in the bearing, offer the waist hole on the described erection support, described erection support is established trip bolt and is fixed on the mounting seat by twisting in the waist hole, and described mounting seat lower end arranges jackscrew.
In the technique scheme, described door closure comprises framework and lid, and described lid is rotationally connected with on the described framework, in described framework buckle is set, and lid is provided with wrenching bar, and an end of described wrench bar stretches out door closure near a side of rotating shaft.
In the technique scheme, the body of rod that lid is positioned at a side of the close rotating shaft of wrench bar door closure is provided with fixed mount.
In the technique scheme, away from the framework of a side of rotating shaft the door closure limiting plate is arranged fixedly at door closure.
The utility model compared with prior art has following beneficial effect: the horizontal installation of cylinder, therefore do not need too high valve box box height is set, and reduced the weight of valve box, make that installation is more convenient; Can be at the sealing station of non-stop-machine condition minor adjustment door closure; Breaking down at cylinder can not automatic opening door under the condition of lid, easily manually opened door closure.
