Abstract
The utility model discloses an integral sealed pneumatic plugboard gate belongs to bulkhead gate technical field, and it includes valve body, valve plate, seal box, scrapes the strip, gyro wheel, upper cover plate, apron down, the valve plate passes through the gyro wheel slip and sets up in the valve body, covers in the top of valve body to set up the upper cover plate, apron under the below of valve body sets up, scrape strip being equipped with of valve plate all around, scrape the strip and set up in the seal box. The utility model discloses an integral sealed pneumatic plugboard gate through set up the gyro wheel on the valve body, can avoid valve plate and valve body direct contact as valve open or when closing, reduce friction power avoids between valve plate and valve body the card to die when meetting the bulk or glue the form material, prolongs the life of valve, simultaneously, this valve body is integral sealed, and processing is convenient, outer not revealing can not appear, need not to change the sealing member in addition, if regularly the row's of opening ash apron discharge inside lime -ash can, it is convenient to examine and repair, long service life.
Description
Technical field
The utility model belongs to bulkhgead gate technical field, is specifically related to the pneumatic plug board gate of integral seal.
Background technique
The slide-valve of bulkhgead gate to be a kind of closure member be parallel gate plate, its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.
Bulkhgead gate is widely used in the industrial trades such as metallurgy, mine, electric power, cement, and mostly current bulkhgead gate is to utilize packing to have the gap between valve body to reach sealing effect to the door-plate that is filled with a sealing, and sealing effect is bad, and complex structure, difficult in maintenance.
Model utility content
Goal of the invention: the purpose of this utility model is to provide integral seal pneumatic plug board gate, not only structure is simple, good seal performance, and is easy to maintenance and safeguards.
Technological scheme: for achieving the above object, the utility model adopts following technological scheme:
The pneumatic plug board gate of integral seal, comprises valve body, valve plate, sealing case, scraping article, roller, upper cover plate, lower cover plate; Described valve plate is arranged in valve body by roller-coaster, covers and be set up cover plate above valve body, arranges lower cover plate in the below of valve body; Be provided with scraping article in the surrounding of described valve plate, scraping article is arranged in sealing case.
Described sealing case is arranged on valve body.
Described sealing case is provided with pressing plate, and described pressing plate to be connected with sealing case by fixing bolt and to be fixed by scraping article.
Described valve body is provided with seal ring.
Described valve plate and cylinders.
The ash discharge port lid for sealing ash-discharge opening is provided with in the bottom of described lower cover plate.
Beneficial effect: compared with prior art, the pneumatic plug board gate of integral seal of the present utility model, by arranging roller on valve body, valve plate can be avoided directly to contact with valve body when valve opening or when closing, reduce friction, avoiding between valve plate and valve body when running into bulk or sticky matter material stuck, extending the working life of valve; Meanwhile, this valve body is integral seal, easy to process, there will not be outward leakage, and without the need to changing Sealing, as long as regularly open ash discharge cover plate to discharge inner lime-ash, maintenance is convenient, long service life.
Accompanying drawing explanation
Fig. 1 is the plan view of the pneumatic plug board gate of integral seal;
Fig. 2 is the plan view of the pneumatic plug board gate of integral seal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As depicted in figs. 1 and 2, the pneumatic plug board gate of integral seal, comprises valve body 1, valve plate 2, sealing case 3, fixing bolt 4, scraping article 5, roller 6, seal ring 7, upper cover plate 8, lower cover plate 9, ash discharge port lid 10 and cylinder 11.
Valve plate 2 is slidably arranged in valve body 1 by roller 6, cover above valve body 1 and be set up cover plate 8, arranging lower cover plate 9 in the below of valve body 1, being provided with the ash discharge port lid 10 for sealing ash-discharge opening in the bottom of lower cover plate 9, upper cover plate 8 and lower cover plate 9 act on simultaneously and being sealed by the upper and lower surface of valve body 1.
Be provided with scraping article 5 in the surrounding of valve plate 2, scraping article 5 is arranged in sealing case 3, and sealing case 3 is arranged on valve body 1, and sealing case 3 is provided with pressing plate, and pressing plate to be connected with sealing case 3 by fixing bolt 4 and to be fixed by scraping article 5, and valve body 1 is provided with seal ring 7.
Valve plate 2 is connected with cylinder 11, and valve plate 2 is opened and closed by the driving of cylinder 11.
Working procedure: when valve open or closedown time, adhesion on valve plate 2 is first wiped off by scraping article 5, due to valve body 1 integral sealing, valve body 1 inside cannot form play air-flow, therefore only have little dust can by the gap between scraping article 5 and valve plate 2 in ash-discharge opening, due to valve body 1 integral sealing, there will not be as other valves due to the wearing and tearing of the Sealing of door-plate or door-plate surrounding outward leakage phenomenon, as long as ash discharge port lid 10 is opened in timing clean out the inner lime-ash accumulated.
