Abstract
The utility model relates to a canned type pneumatic gate valve for buggy. The disk seat has the cavity, and the valve body is fixed to the left end of disk seat, right -hand member fixed seal seat, the right -hand member of the valve plate of application valve body switch and the left end of valve rod are articulated, and it is articulated that the right -hand member of valve rod passes through the middle part of cavity and seal receptacle and the connecting rod of disk seat, the both ends of connecting rod respectively around with cylinder, the piston articulated, the front and back cylinder, fix respectively on the antetheca of disk seat, seal up fixed upper and lower sealed apron on the upper and lower terminal surface of disk seat respectively, it is sealed with the cavity of disk seat. Its simple structure, the leakproofness is good, uses safe and reliable.
Description
Technical field
The utility model belongs to push-pull valve, particularly a kind of coal dust sealed type pneumatic push-pull valve.
Background technology
Metallurgy and building materials, chemical field have a large amount of various stoves to adopt coal dust as combustion fuel, divide at coal dustJoin and course of conveying in to use many valves (gate) and control the flow direction and the break-make of coal dust, push-pull valve is with itSimple in structure, reliable in action, the advantage that installing space is little are used widely. The coal dust that kiln burning is usedThere is feature inflammable, explosive, that fineness is high (200 orders, coal dust particle size is less than or equal to 75 microns),Its good fluidity, the danger of easily can blasting with air formation aerosol and while meeting naked light after being scattered. CommonThough push-pull valve is owing to lacking sealing between plate and valve body or having a sealing, because valve plate motion wearing and tearing causeGap, easily causes the leakage of coal dust, causes the waste of fuel and the pollution of environment and potential safety hazard.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of coal dust sealed type pneumatic push-pull valve.It is simple in structure, and good airproof performance is safe and reliable.
The technical scheme in the invention for solving the technical problem is: valve seat has cavity, a left side for valve seatEnd fixed valve body, right-hand member fixing seal seat, the right-hand member of the valve plate of described application valve body switch and the left end of valve rodHinged, the right-hand member of valve rod by the cavity of valve seat and the middle part of seal receptacle and connecting rod hinged, connecting rod two endsRespectively with front and back cylinder, piston hinge, front and back cylinder, be separately fixed on the antetheca of described valve seat instituteState on the upper and lower end face of valve seat the fixing upper and lower seal cover board of sealing respectively, by the cavity sealing of valve seat.
1), adopt cylinder and compressed air as executive component and power the utlity model has following advantages:Source, can not produce electric spark when action, the suitable region that has requirement of explosion proof is used; 2), adopt totally-enclosedHermetically-sealed construction, partly has upper-lower seal cover plate to carry out beyond the fluid passage of valve body hermetically enclosed, stops coal dustLeakage; 3), cylinder is external, cylinder piston rod can not be polluted and be worn and torn; 4), adopt nip drum guiding,Guarantee the movement locus of valve plate, simple in structure, manoeuvrable, lightweight, without jam, cut off fast, specialBe applicable to conveying and the Flow-rate adjustment of coal dust and all kinds of solid micro-powder materials, install and be not subject to angle limits, operationConvenient, can adjust at any time aperture.
Brief description of the drawings
