Abstract
The utility model discloses a connection device for a safety valve. The connection device comprises a valve body and a valve body installation base, a seal cushion, a spool, a valve rod, a valve cap and a spring are arranged in the valve body, two clamping heads are integrally arranged on the lateral side outside the valve body installation base, L-shaped clamping grooves matched with the two clamping heads are formed in the lower end of a valve body, a step hole is formed in the lower end of the valve body, an elastic seal element is arranged at the step position of the step hole, the elastic seal element comprises an outside rubber seal ring and a spring assembly wrapped inside the rubber seal ring, and the lower end of the elastic seal element is in contact with the valve body installation base in a butting mode. A clamping method is adopted between the safety valve and the valve body installation base, so that the safety valve is convenient, easy, fast and efficient to install. In addition, the step structure with the elastic seal element arranged in the valve body can effectively form sealing between the valve body and the valve body installation base, ensure that air is not leaked between the valve body and the valve body installation base, and avoid the phenomenon of air leakage and scrap.
Description
Technical field
The utility model belongs to air compressor accessory technical field, the particularly connection set of a kind of safety valve and air compressor.
Background technique
Safety valve on existing air compressor and air compressor are all that the mode being threaded connection is installed, and not only installation efficiency is low for it, and if between screw thread, do not process can produce gas leak phenomenon, cause scrapping of safety valve.
Model utility content
In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is to provide the new Joining Structure of a kind of safety valve and air compressor.
The technological scheme that the utility model is taked for its technical problem of solution is:
A kind of connection set of safety valve, comprise valve body and valve body fitting seat, in valve body, be connected with in turn sealing gasket from bottom to top, spool, valve rod and bonnet, at the outer spring that is arranged with of valve rod, between valve rod and bonnet, be slidably connected, outside side integral type at described valve body fitting seat is provided with two dops, be provided with the L shaped draw-in groove coordinating with two dops in the lower end of described valve body, inside, lower end at described valve body is provided with a step hole, step place at step hole is provided with elastomer seal, described elastomer seal comprises outside rubber seal and is wrapped in the spring assembly of rubber seal inside, elastomer seal lower end contacts valve body fitting seat.
In described spring assembly, be densely covered with spring.
Described dop to the distance at valve body fitting seat top equals the distance of step place to L shaped draw-in groove upper end portion in valve body.
The center of described elastomer seal is provided with a center hole, and the equal diameters of the aperture of center hole and described step hole, in described valve body fitting seat, sets out pore, and described air outlet hole diameter equals described elastomer seal center-hole diameter.
The beneficial effects of the utility model: the utlity model has simple in structure, between safety valve and valve body fitting seat, adopt that snap fit makes safety valve simple installation, quick, efficiency is high, and the staircase structural model of establishing in valve body with elastomer seal can be effectively to forming sealing between valve body and valve body fitting seat, guarantee between valve body and valve body fitting seat air tightly, avoid the generation of the gas leakage phenomenon of scrapping.
