Abstract
The utility model relates to a new structure rubber tubular valve, which is composed of an upper and a lower valve bodies, a handwheel, a valve cover, a valve rod, a clamping ring, press plates and a rubber pipe. The utility model is characterized in that a valve cavity is composed of the upper valve body and the lower valve body, the upper part in the inner part of the valve cavity is provided with press plates which are connected with the valve rod and can move up and down in the valve cavity, and the lower part of the inner part of the valve cavity is provided with the rubber pipe; a pipeline can be closed and cut off through press plates with the same curvature and the downward half-moon-shaped convex part of the lower valve body which are matched with each other; simultaneously, in the process of lifting up, the rubber pipe is lifted by the valve rod through the concave part of press plates which is connected with a small convex column of the rubber pipe to ensure smooth rubber pipe. Compared with traditional similar valves, the utility model has the advantages of simple structure and convenience operation.
Description
The utility model relates to a kind of new structure rubber pipe valve, belongs to valve type.
Traditional rubber pipe valve (claiming pipe clip valve, throughway valve again) is to utilize rotation hand wheel, makes big small valve-rod drive the upper and lower to-and-fro motion compression of upper and lower clamping plate or loosens the switching that glue pipe socket is realized valve.Its feature is simple in structure, flexible operation, airtight performance is good, dismounting is easy to maintenance, need not packing seal, two ends are connected with pipeline does not need to add sealing gasket figure in addition, winter hardiness is good, because liquid medium flows in whippy sebific duct, got rid of because of the liquid crystallization and caused the possible bursting by freezing of valve housing.Its defective is: sebific duct has time of 85% to be in closed condition approximately, and because of sebific duct is in compressive state for a long time, sealing part two ends limit ftractures easily; In addition, its fluid passage of flexible sebific duct reduces relatively, and resistance strengthens; Because the colloid pipe easily produces plastic deformation, so sebific duct is short working life; Moreover because fastening device device complexity, stuck easily.
The purpose of the present utility model is to provide a kind of new structure rubber pipe valve, wishes numerous advantages that it can keep traditional rubber pipe valve, can make simultaneously that its sealing is reliable more, long service life, easy to maintenance, structure is simpler.
This new structure rubber pipe valve is made up of upper valve body (4), following valve body (9), handwheel (1), valve gap (2), valve rod (3), snap ring (5), pressing plate (6) and sebific duct (7), in the valve pocket that it is characterized in that being made up of upper valve body (4) and following valve body (9), its top is being provided with pressing plate (6), its underpart of being connected with valve rod (3) and can moving up and down again and is being close to down that valve body (9) bottom is being provided with sebific duct (7) in valve pocket; The top-arc part that described pressing plate (6) and following valve body (9) are protruding same curvature semilune, this semilune pressing plate (6) downwards is provided with a shrinkage pool that matches connection with small convex pillar on the sebific duct (7).
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is that the B-B of accompanying drawing 1 is to sectional view.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
This new structure rubber pipe valve of the utility model introduction is a kind of improvement to traditional rubber pipe valve.Its major character is in the valve pocket of being made up of upper valve body (4) and following valve body (9), its top be provided be connected with valve rod (3) and again can be in valve pocket upper and lower mobile pressing plate (6), its underpart is close to down that valve body (9) bottom then is being provided with sebific duct (7); Central upper portion at this sebific duct (7) is provided with a projection.Simultaneously pressing plate of the present invention (6) is protruding same curvature semilune downwards with following valve body (9), the top of semilune pressing plate (6) arc central part be provided with one with last the match shrinkage pool of connection of small convex pillar of sebific duct (7).
The working principle of this rubber pipe valve is: when operator's rotation hand wheel, valve rod (3) drives pressing plate (6) chute on the leg in the last valve and moves downward; Because pressing plate (6) is with the downward protruding semilune of curvature with following valve body (9), so pressing plate (6) finally can cut out the sebific duct (7) that serves as infusion channel originally to lower compression sebific duct (7), sebific duct this moment (7) is in semilune; Otherwise then open.For preventing to be in compressive state for a long time, to produce plastic deformation because of sebific duct; Pressing plate of the present utility model (6) fuses through shrinkage pool and sebific duct (7), owing to the effect to upper pulling force, even hose aging also can be avoided the plastic deformation and the adhesion of sebific duct (7), helps the current of conveying material when opening.
This New structure rubber tubular valve can be contained in arbitrarily on the pipeline, has both kept the advantage of traditional hose valve comprehensively, While makes again structure, operation is more simple, maintenance is more convenient, and can increase the service life.
Claims (1)
1, a kind of new structure rubber pipe valve is made up of upper valve body (4), following valve body (9), handwheel (1), valve gap (2), valve rod (3), snap ring (5), pressing plate (6) and sebific duct (7), in the valve pocket that it is characterized in that forming by upper valve body (4) and following valve body (9), its top is being provided with the pressing plate (6) that is connected and can moves up and down again with valve rod (3) in valve pocket, valve body (9) bottom had been provided with sebific duct (7) under its underpart was close to; Described pressing plate (6) and following valve body (9) are protruding semilune with curvature downwards, and the top-arc part of this semilune pressing plate (6) is provided with a shrinkage pool that matches connection with small convex pillar on the sebific duct (7).
