Description
Technical field
The utility model relates to a kind of seal arrangement, and specifically a kind of pneumatic, Manual flashboard valve sealing means, belongs to push-pull valve technical field of sealing technology.
Background technique
Push-pull valve is a kind of flashboard and the valve seat valve that seals of close contact all the time, and its principle is round mouth flashboard having a latus rectum size, is opened and closed the action making round mouth on flashboard finish total detachment with latus rectum and match by flashboard.The advantage of this valve is that valve body latus rectum is without groove, and medium can not block by jam, and has full-bore flow characteristics, and its sealing configuration can divide soft seal, hard sealing structure.Penetrating knife type gate valve has precise construction, good manufacturability, the features such as compact structure, and seal valve seat designs for bascule, and have anti-wear and automatic compensation function, thus the life-span is longer.In closedown and opening process, valve seat is close to motion with flashboard always, and valve opening and closing power is stablized, and has features such as cutting off medium.
As shown in Figure 1, traditional push-pull valve is by valve frame 1, the valve plate 2 being located at valve frame 1 inside, be symmetricly set on the right support plate 9 of valve plate about 2 both sides, Stamping Steel Ribbon 7, pressing plate 6 forms, and two right support plates 9 are arranged on valve frame 1 respectively, and match with the height of valve plate 2 in the gap between two right support plates 9, and valve plate 2 can move left and right between two right support plates 9, Stamping Steel Ribbon 7, and to be contacted with valve plate 2 by bolt presses between right support plate 9 and pressing plate 6.The material selection wool felt of described Stamping Steel Ribbon 7 is filled, but this kind of sealing structure effect is bad.During work, air cylinder driven valve plate does horizontal motion on roller, ends and open material, and the material of adhesion when valve plate bounces back is blocked in valve internal by Stamping Steel Ribbon, reduces dust and overflows.Owing to there being the material such as sand, cement inside material, sand can extrude wool felt, makes gap between Stamping Steel Ribbon and valve plate become large, felt even can be caused to come off, and material is easily emerged, and sealing effect is poor, leaking material problem for solving, being also provided with water collecting funnel and remedying, complex structure.In addition, said structure Stamping Steel Ribbon is changed comparatively complicated, and need carry out disintegration to gate valve can change.
Summary of the invention
For above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of pneumatic, Manual flashboard valve sealing means, improves sealing effect, avoids the leakage material phenomenon because sealing effect decline occurs, can change Stamping Steel Ribbon easily.
To achieve these goals, the utility model one is pneumatic, Manual flashboard valve sealing means, comprise Stamping Steel Ribbon, pressing plate and right support plate, also comprise left support plate, described left support plate and right support plate are respectively equipped with two pieces, are symmetricly set on the both sides up and down of valve plate, and are installed on valve frame, match with the height of valve plate in gap between the left and right dunnage of two pieces, and valve plate can move left and right between the left and right dunnage of two pieces;
Described left support plate and right support plate are provided with sealed cover, described Stamping Steel Ribbon is positioned between left support plate and right support plate and left and right dunnage is close in the left and right sides, described adjusting bolt is passed sealed cover and is crimped on Stamping Steel Ribbon by pressing plate, and described adjusting bolt is threaded with sealed cover.
Further, sealing gasket is provided with between sealed cover and right baffle-plate, right baffle plate.
Preferably, the material of Stamping Steel Ribbon is oil immersion asbestos packing.
Further, sealed cover is provided with locking nut, adjusting bolt is crimped on pressing plate by locking nut.
Compared with prior art, the utility model increases controlling device, when after sealing material wearing and tearing, sealing material is enable to compress valve plate by adjusting bolt and pressing plate, reduce because sealing effect declines the leakage material problem occurred, and be convenient to change Stamping Steel Ribbon, eliminate water collecting funnel, structure is simpler simultaneously.In addition, sealing material adopts oil immersion asbestos packing, has the wear resistance of having taught, longer service life.The utility model structure is simple, is convenient to manufacture, and low cost of manufacture.
Accompanying drawing explanation

Fig. 2 is the utility model structural representation.
In figure: 1. valve frame, 2. valve plate, 3. sealing gasket, 4. sealed cover, 5. adjusting bolt, 6. pressing plate, 7. Stamping Steel Ribbon, 8. left support plate, 9. right support plate, 10. locking nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the utility model one is pneumatic, Manual flashboard valve sealing means, be made up of Stamping Steel Ribbon 7, pressing plate 6, right support plate 9 and left support plate 8, described left support plate 8 and right support plate 9 are respectively equipped with two pieces, be symmetricly set on the both sides up and down of valve plate 2, and being installed on valve frame 1, match with the height of valve plate 2 in the gap between the left and right dunnage 8,9 of two pieces, and valve plate 2 can move left and right between the left and right dunnage 8,9 of two pieces;
Described left and right dunnage 8,9 is provided with sealed cover 4, described Stamping Steel Ribbon 7 is positioned between left support plate 8 and right support the plate 9 and left and right sides and is close to left and right dunnage 8,9, described adjusting bolt 5 is passed sealed cover 4 and is crimped on Stamping Steel Ribbon 7 by pressing plate 6, and described adjusting bolt 5 is threaded with sealed cover 4.
As the improvement of the utility model to technique scheme, between described sealed cover 4 and left and right dunnage 8,9, be provided with sealing gasket 3, be conducive to improving sealing effect.
As the optimal way of the utility model to technique scheme, the material of described Stamping Steel Ribbon 7 is preferably oil immersion asbestos packing, wear resistance, longer service life, saves cost, certainly also can select other sealing material, but wear resistance is all worse than oil immersion asbestos packing.
As the further improvement of the utility model to technique scheme, described sealed cover 4 is provided with locking nut 10, adjusting bolt 5 is crimped on pressing plate 6 by locking nut 10, locking nut 10 can lock adjusting bolt 5 effectively, the phenomenon loosened is there is after preventing adjusting bolt 5 from using for a long time, ensure Stamping Steel Ribbon 7 all the time with valve plate 2 close contact, improve further the sealability of push-pull valve.
During work, air cylinder driven valve plate 2 does horizontal motion on roller, ends and open material, and the material of adhesion when valve plate 2 bounces back is blocked in valve internal by Stamping Steel Ribbon 7, thus reduces dust spilling.
