Abstract
The present invention relates to a clamping valve with a pneumatic pipe, which is characterized in that a rubber pipe of a pipe vale and a valve body are inlaid by at least three dovetail grooves of uniform distribution. The present invention aims to design the clamping valve with a pneumatic pipe, which has convenient manufacture and good sealing performance. Compared with the prior art, the clamping valve with a pneumatic pipe has the advantages of simple structure, flexible operation, good sealing performance, long service life, etc.
Description
Technical field
The present invention relates to pneumatic pipe clip valve, particularly a kind ofly be widely used in the pneumatic pipe clip valve that industries such as petrochemical industry, agricultural chemicals, dyestuff, smelting are carried high solids slurries and the medium that is corrosive.
Background technique
Traditional pneumatic pipe clip valve is for finishing unlatching, throttle down action, make the pipe clamp rubber pipe adopt indirect machinery to tend to act often according to setting deformation work, or the pipe clamp sebific duct is made into complicated shape chamber finishes, the hose manufacturing process complexity of this kind structure, simultaneously, valve body is combined by the half slide structure of symmetry, when closing, the valve body junction leaks gas easily, causes compressed-air actuated pressure to reduce, the effect that valve is lost close.
Summary of the invention
The objective of the invention is to design a kind of pneumatic pipe clip valve of easily manufactured, good airproof performance.
In order to achieve the above object, the present invention adopts following technical solution: a kind of pneumatic pipe clip valve, comprise valve body, pipe clamp rubber pipe, sealing rubber pad, valve body is provided with suction port and air outlet, it is characterized in that between pipe clamp rubber pipe middle part and the valve body being halved together by uniform three or many dovetail grooves on the valve body.Because the connecting structure between pipe clamp sebific duct and the valve body, closing and open directly of pipe clamp sebific duct operated by pressurized air, good airproof performance, and also the pipe clamp sebific duct is simple in structure, and easily manufactured.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the present embodiment structural drawing.
Fig. 2 is an A-A sectional view (opening state) among Fig. 1.
Fig. 3 is an A-A sectional view (closed condition) among Fig. 1.
Fig. 4 is pipe clamp rubber pipe modular construction figure among Fig. 1.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, present embodiment comprises valve body (1), pipe clamp rubber pipe (2), and valve body is to be identical split-type structural up and down, is sealed by sealing rubber pad (3) between them, and valve body (1) is provided with suction port (13) and air outlet (14).The outside, pipe clamp rubber pipe (2) middle part is provided with three uniform slat gum fixed strips (9), the dovetail groove (4) that it and valve body (1) joint are provided with is halved together, 60 ° of degree of dislocation are uniform between guiding muscle (5) on the valve body (1) and the dovetail groove (4), make the space between pipe clamp rubber pipe (2) and the valve body (1) be divided into three uniform pressurized air spaces.Change the damage that causes for the local plastic that reduces valve pipe clamp rubber pipe in off position the time simultaneously, on the pipe clamp rubber pipe, be provided with sealing clip (10), be provided with sealing projected edge (11) (as Fig. 4) in the inboard of the pipe clamp rubber pipe relative with sealing clip (10) with the corresponding inboard of rubber fixed strip (9).
In addition, the influence sealing in order to prevent pipe clamp rubber pipe flange seal motion wriggling, pipe clamp rubber pipe end face is whole flanged sealing surface, is provided with shrinkproof prominent edge (8) behind its rubber flange facing, and shrinkproof groove (7) coupling on it and the valve body constitutes the port sealing limit stoper.Simultaneously, take into full account the working life of pipe clamp rubber pipe, and the whole plastic deformation of the pipe clamp rubber pipe that reduces to be in the valve closing state as possible, make pipe clamp rubber tube terminal inlet caliber less than middle caliber with unique hole enlargement design, connect by the transition of reducing arc (12) section between inlet caliber and the middle caliber, make the pipe clamp rubber pipe rely on the geometric form chamber to change pass valve and the unlatching of finishing valve.
After valve is installed in pipeline, connect gas solenoid valve and reduction valve at valve suction port (13), and reduction valve is debugged to the valve closing point, prevent the suction pressure interference and damage rubber pipe.Also connect gas solenoid valve in the valve air outlet, suction port gas solenoid valve and air outlet gas electromagnetism switch mutually.Open-minded when suction port, the air outlet is closed so, and the pipe clamp sebific duct of pipe clip valve manifests the closed condition as Fig. 3.Work as inlet close, the air outlet is open-minded, and pipe clip valve pipe clamp sebific duct manifests the opening state as Fig. 2.
In sum, the present invention compared with prior art has the following advantages:
1, simple in structure, easily manufactured.
2, flexible operation
3, good airproof performance.
4, long service life.
