Abstract
The utility model relates to a valve device and in particular relates to a safety valve. In order to solve the technical problem, the technical scheme adopted by the utility model is that the safety valve comprises a valve body, wherein the valve body is formed by assembling a valve seat and a top cover; a spring and a guide rod are formed in the valve body; the guide rod is positioned in the center of the valve body and is positioned in the axial center of the spring; and a rubber protective cover is formed at the combination of the valve seat and the top cover. The safety valve has the beneficial effect that the rubber protective cover is formed at the combination of the valve seat and the top cover so that dust and water can be prevented from entering the mechanical structure of the safety valve and the influence of the dust and the water to the mechanical structure of the safety valve can be effectively avoided.
Description
Technical field
The utility model relates to valving, relates in particular to a kind of safety valve.
Background technique
Safety valve of the prior art comprises valve seat, and top cover forms the valve pocket of safety valve after this valve seat and the assembling of this top cover, be provided with guide rod in this valve pocket, and an end of the close valve seat of this guide rod is provided with valve plate, be positioned on guide rod this valve plate above be provided with spring.In daily life, there are many dusts many, under the many and washy environment of dust, often rainwater can occur, dust is trickled down in relief valve port, causes caking or blocking phenomenon.Because the dust in external environment can enter in the valve body of safety valve, reduce the performance of mechanical structure in safety valve in addition, affect the release flow of safety valve.
The model utility content
Technical problem to be solved in the utility model is to provide and a kind ofly can prevents effectively that thereby extraneous dust and water from entering the safety valve that reduces mechanical structure performance in valve body in valve body.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of safety valve; comprise valve body; described valve body has valve seat and top cover to be assembled; be provided with spring and guide rod in described valve body; described guide rod is positioned at the center of valve body; described guide rod also is positioned at the axial centre of spring, and the junction of described valve seat and top cover is provided with protecting jacket.
Further, described protecting jacket adopts rubber material to make.
The beneficial effects of the utility model are: be provided with in the junction of valve seat and top cover the protecting jacket that rubber material is made, can prevent that dust and water from entering into the mechanical structure of safety valve, thereby effectively avoid dust and water on the impact of safety valve mechanical structure.
