Abstract
The invention relates to a pneumatic control valve which comprises a valve body and a valve element arranged in the inner cavity of the valve body. The valve body comprises a shell body, an upper tubular inner cavity, an elliptic inner cavity, a lower tubular inner cavity and an air inlet, the upper tubular inner cavity, the elliptic inner cavity and the lower tubular inner cavity are arranged in sequence and are communicated in sequence, the air inlet is formed in the shell body, the air inlet is formed in the cavity wall of the elliptic inner cavity, and the valve element is provided with a middle through hole, a wear-resisting rubber layer and a tyre fabric reinforcement layer from inside to outside in sequence. The pneumatic control valve is good in sealing effect, the wear resistance of the valve element is good, the service life is long, and bearing pressure is high. The problem that the pneumatic control valve is poor in sealing or the valve element is easy to pull out is solved, the structure is simplified, and processing difficulty is lowered. The problems that an existing pneumatic control valve element is not resistant to wear and bearing pressure is low are solved.
Description
Technical field
The present invention 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.
Summary of the invention
The object of this invention is to provide a kind of Pneumatic valve, solve the above-mentioned problems in the prior art.
The technological scheme that the present invention 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, and 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 invention has the beneficial effects as follows: the invention provides a kind of Pneumatic valve, sealing effect is better, 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 present invention;
Fig. 2 is the schematic diagram of the valve body of a kind of Pneumatic valve of the present invention;
Fig. 3 is the schematic diagram of a kind of Pneumatic valve of the present invention.
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 invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
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, for stored air, and when air pressure reaches certain pressure, compressed the closing of spool internal diameter meeting, thereby 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 invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
