Novel valve cover structure of breaking hammer reversing valve

Abstract

The utility model provides a novel valve cover structure of a breaking hammer reversing valve, and belongs to the technical field of breaking hammers. The breaking hammer reversing valve cover solves the problem that an existing breaking hammer reversing valve cover is generally of an integrated structure, the whole valve cover needs to be replaced during maintenance and replacement, and the replacement cost is high. According to the novel valve cover structure of the breaking hammer reversing valve, the reversing valve comprises a valve body, the valve cover structure is installed on the valve body, the valve cover structure comprises a valve cover body and a cover plate which are arranged in a split mode and fixedly connected, and a gasket is arranged between the valve cover body and the cover plate. The utility model has the advantages that the replacement cost is reduced, and the wear resistance and sealing dust prevention are improved.

[0003] The purpose of the utility model is to provide a new valve cover structure of a breaker hammer reversing valve to solve the above problems in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a new valve cover structure for a breaker hammer reversing valve, the reversing valve includes a valve body, and the valve cover structure is installed on the valve body. It is characterized in that the valve cover structure includes a valve cover body and a cover plate that are separately arranged and fixedly connected, and a gasket is arranged between the valve cover body and the cover plate.

[0005] In the above-mentioned novel valve cover structure of the breaker hammer reversing valve, a plurality of sealing rings are provided between the valve cover body and the housing.

[0006] In the above-mentioned novel valve cover structure of the breaker hammer reversing valve, multiple sealing rings 2 are provided between the cover plate and the housing.

[0007] Compared with the existing technology, the new valve cover structure of the breaker hammer reversing valve has the advantages of reducing replacement costs, improving wear resistance and sealing and dust prevention. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a cross-sectional view of the new valve cover structure of the breaker hammer reversing valve.

[0009] In the figure, 1. Valve cover body; 2. Cover plate; 3. Gasket; 4. Sealing ring 1; 5. Sealing ring 2; 6. Valve body. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, the new valve cover structure of the breaker hammer reversing valve includes a valve body 6, and the valve cover structure is installed on the valve body 6. The valve cover structure includes a valve cover body 1 and a cover plate 2 that are separately arranged and fixedly connected. A gasket 3 is provided between the valve cover body 1 and the cover plate 2, which has the effects of wear resistance, sealing, and dust prevention.

[0012] Because of the split setting, when replacing, can be replaced individually, reduce the replacement cost.

[0013] Preferably, the valve cover body 1 and the shell are provided with several sealing rings 4; the cover plate 2 and the shell are provided with multiple sealing rings 5.

[0014] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0015] Although the valve cover body 1, cover plate 2, gasket 3, sealing ring 4, sealing ring 5, valve body 6 and other terms are used more in this paper, but not to exclude the possibility of using other terms. Use these terms is only to more conveniently describe and explain the essence of the present application; to be interpreted as any kind of additional restrictions are contrary to the spirit of the present application.
