Description
Technical field
This utility model relates to a kind of push-pull valve, especially relates to a kind of heavy caliber multiple-piece push-pull valve.
Background technology
The manufacturing process discharge duct of the manufacturing enterprises such as quasiconductor, microelectronics and liquid crystal panel, owing to easily adhering to heap
Accumulated powder dirt, so needing to switch political loyalty at each pipeline rout to locate to install a valve, it is simple to close during line clear the last period
Back segment passage, in order to avoid air loss is excessive causes the machine of delaying.Butterfly valve class rotary shaft mode valve dust attachment pile up after be difficult to into
Row effectively intercepts, thus push-pull valve can only be selected to cut off as pipeline, and when there is heavy caliber pipeline, existing single plate exists
Following shortcoming:
1) stroke is too big, and technique exhaust duct is generally mounted to equipment interlayer or hangs on floor top, below pipeline
Being production equipment and passageway, site space can not meet the stroke of push-pull valve；
2) valve body deadweight is overweight, the intensity of plate during for meeting heavy caliber, is typically only possible by thickening plate and increase
Strengthen realizing, necessarily cause product deadweight excessive, but site safety production aspect does not the most allow the situation that push-pull valve is overweight；
3) passive delivery, field apparatus does not allows, and is unfavorable for manually opened etc..
Utility model content
It is novel that technical problem to be solved in the utility model is to provide a kind of simple in construction, easy to operate, space hold
Little, and can be manually opened heavy caliber multiple-piece push-pull valve.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of heavy caliber multiple-piece push-pull valve, including the valve body of rectangle, guided wheel slot I, guided wheel slot II, guided wheel slot III and
Four plates, the axis of valve body is provided with dividing plate, and the top of dividing plate and bottom are provided with U-lag, and the central authorities of dividing plate are provided with through hole,
Guided wheel slot I and guided wheel slot III is fixed on valve body after being each passed through U-lag, and guided wheel slot II is fixed on valve body after through hole,
Dividing plate position between guided wheel slot I and guided wheel slot II, between guided wheel slot II and guided wheel slot III is equipped with locating slot, inserts
The side of plate contacts with locating slot after the sidewall of valve body, and top and the bottom of plate connect with the guide wheel in corresponding guided wheel slot
Touching, the opposite side of plate is provided with pull bar.
Further, it is provided with sealing strip between sidewall and the plate of described valve body.
Compared with prior art, the utility model has the advantages that: push-pull valve simple in construction of the present utility model is novel, operation
Convenient, use the design of multi-disc plate, while realizing manual operation, it is possible to effectively shorten the stroke of plate, reduce
Take up room and conduct oneself with dignity, and meeting the large diameter pipeline requirement for plate intensity, it is advantageously ensured that the safety of produced on-site.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A-A to structural representation；
Fig. 3 is use state diagram of the present utility model.
Wherein, 1, valve body, 2, guided wheel slot I, 3, guided wheel slot II, 4, guided wheel slot III, 5, dividing plate, 6, locating slot, 7, plate,
8, pull bar, 9, sealing strip, 10, U-lag, 11, through hole.
Detailed description of the invention:
As depicted in figs. 1 and 2, a kind of heavy caliber multiple-piece push-pull valve, including the valve body 1 of rectangle, guided wheel slot I2, guided wheel slot
II3, guided wheel slot III4 and four plates 7, the axis of valve body 1 is provided with dividing plate 5, and top and the bottom of dividing plate 5 are provided with U-shaped
Groove 10, the central authorities of dividing plate 5 are provided with after through hole 11, guided wheel slot I2 and guided wheel slot III4 are each passed through U-lag 10 and are fixed on valve body 1
On, guided wheel slot II3 is fixed on valve body 1 after through hole 11, and dividing plate 5 is between guided wheel slot I2 and guided wheel slot II3, guided wheel slot
Position between II3 and guided wheel slot III4 is equipped with locating slot 6, the side of plate 7 through valve body 1 sidewall after with locating slot
6 contacts, the top of plate 7 contacts with the guide wheel in corresponding guided wheel slot with bottom, and the opposite side of plate 7 is provided with pull bar 8.
In order to make valve body 1 be isolated from the outside, this utility model is provided with sealing strip between the sidewall and plate 7 of valve body 1
9。
During as it is shown on figure 3, use the cleaning on push-pull valve of the present utility model laggard line pipe road, operator hold and draw
After bar 8, plate 7 is slid in locating slot 6 one by one or simultaneously along the guide wheel in guided wheel slot, it is achieved before and after pipeline between section
Isolation, realizes the isolation between valve body 1 and the external world by sealing strip 9 simultaneously, thus the equipment that effectively prevent is because of air loss mistake
Machine of the delaying phenomenon caused greatly.
Owing to inserted sheet valve of the present utility model uses the design of multi-disc plate, state the same of manual operation in realization
Time, additionally it is possible to effectively shorten the stroke of plate 7, reduce and take up room and conduct oneself with dignity, and meet large diameter pipeline for plate intensity 7
Requirement, it is advantageously ensured that the safety of produced on-site.
