Abstract

The utility model relates to a pneumatic control valve comprising a valve body and a valve spool arranged in an inner cavity of the valve body. The valve body comprises a shell, an upper cylindrical inner cavity, an oval inner cavity, a lower cylindrical inner cavity and an air inlet, the upper cylindrical inner cavity, the oval inner cavity and the lower cylindrical inner cavity are arranged and communicated with one another in sequence, the air inlet is formed in the shell and located on the cavity wall of the oval inner cavity, and the valve spool is provided with a middle through hole, a wear-resistant rubber layer and a cord fabric reinforcing layer sequentially from inside to outside. The pneumatic control valve is good in sealing effect, and the valve spool is good in wear resistance, long in service life and high in bearing pressure; the problem that the pneumatic control valve is poor in sealing or the valve spool is easily drawn out is solved, the structure is simplified, and processing difficulty is lowered; the problem that a valve spool of an existing pneumatic control valve is easily worn and low in bearing pressure is solved.

Description

A kind of Pneumatic valve
Technical field
The utility model relates to a kind of Pneumatic valve.
Background technique
Pinch valve is the valve that a kind of chemical industry and bargh are often used, and valve internal is rubber bushing, according to control mode, is divided into manually, pneumatic, the kind such as electronic, use amount is larger, apply comparatively extensive, and gas control pinch valve is wherein bad due to sealing, through the flange part position of being everlasting, tight gum cover cannot be leaked air and then causes to the state that valve pocket cannot be closed, valve bush bearing capacity is lower in addition, easily explosion, not wear-resisting, working life is shorter, changes frequent.
Model utility content
The purpose of this utility model is to provide a kind of Pneumatic valve, solves the above-mentioned problems in the prior art.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of Pneumatic valve, comprise valve body and the spool that is arranged on described body cavity, described valve body comprises housing, upper tubular inner chamber, oval-shaped cavity, lower tubular inner chamber and air intlet, described upper tubular inner chamber, oval-shaped cavity and lower tubular inner chamber set gradually and are communicated with successively, on described housing, be provided with described air intlet, described air intlet is positioned on the chamber wall of described oval-shaped cavity, described spool prolongs radial direction and is provided with successively from inside to outside middle through-hole, abrasive rubber layer and cord fabric enhancement layer.
Further, in the axial both ends of the surface of described valve body, be respectively arranged with housing groove, on described spool, be provided with the flange rubber circle with described housing groove fitted seal.
Further, in the axial both ends of the surface of described valve body, be respectively arranged with the flange hole for clamping bolt.
Further, described valve body adopts integral cast to process.
The beneficial effects of the utility model are: the invention provides a kind of Pneumatic valve, sealing effect is better, and the wear resistance of spool is good, and long service life and bearing capacity are high; Solve the problem that Pneumatic valve sealing is bad or spool is easily drawn out of, and simplified the structure, reduced difficulty of processing; Solved the problem that existing Pneumatic valve spool is not wear-resisting and bearing capacity is lower.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the spool of a kind of Pneumatic valve of the utility model;
Fig. 2 is the schematic diagram of the valve body of a kind of Pneumatic valve of the utility model;
Fig. 3 is the schematic diagram of a kind of Pneumatic valve of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, housing groove, 2, air intlet, 3, flange hole, 4, abrasive rubber layer, 5, cord fabric enhancement layer, 6, flange rubber circle, 7, middle through-hole, 801, upper tubular inner chamber, 802, oval-shaped cavity, 803, lower tubular inner chamber, 9, housing.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of Pneumatic valve, comprise valve body and the spool that is arranged on described body cavity, described valve body comprises housing 9, upper tubular inner chamber 801, oval-shaped cavity 802, lower tubular inner chamber 803 and air intlet 2, described upper tubular inner chamber 801, oval-shaped cavity 802 and lower tubular inner chamber 803 set gradually and are communicated with successively, on described housing 9, be provided with described air intlet 2, described air intlet 2 is positioned on the chamber wall of described oval-shaped cavity 802, described spool is provided with middle through-hole 7 from inside to outside successively, abrasive rubber layer 4 and cord fabric enhancement layer 5.In the axial both ends of the surface of described valve body, be respectively arranged with housing groove 1, on described spool, be provided with the flange rubber circle 6 with described housing groove 1 fitted seal.In the axial both ends of the surface of described valve body, be respectively arranged with the flange hole 3 for clamping bolt.
Described valve body adopts integral cast to process, and two ends become tubular inner chamber, and centre is oval-shaped cavity, and for stored air, when air pressure reaches certain pressure, spool internal diameter can compressedly be closed, thus closed flow; While opening outside Decompression valves, pressurized air is discharged, and spool restores to the original state, and runner is opened.By housing, structurally coordinate with spool, play seal action, and play sealing effect by bolton flange, spool can not extracted out from valve body because bearing capacity is excessive like this; Spool adopts the abrasive rubber that is particularly suitable for slurry as inside liner in addition, cord fabric is as enhancement layer, to spool, adopt water cloth to be wound around evenly pressurization, make cord unfold distortionless phenomenon, and extend to flange position, improved the bearing capacity of valve bush, made whole valve seal effective, the working life of greatly having improved Pneumatic valve.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
