Drawings
FIG. 1 is a schematic cross-sectional view of an embodiment of the present utility model;
fig. 2 is a partial enlarged view of an embodiment of the present utility model.
Description of the embodiments
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
As shown in fig. 1-2, a check valve with a replaceable valve clack seat comprises a valve body 1, a valve seat 6, a valve clack 4 and a valve cover 2, wherein a valve rod 3 is arranged in the valve body 1, the valve clack 4 is hinged to the valve rod 3 and can rotate around the valve rod 3, the valve cover 2 is detachably connected with the valve body 1, the valve seat 6 is arranged between the valve cover 2 and the valve body 1, the valve body 1 and the valve cover 2 are correspondingly provided with inclined planes, a valve seat mounting groove 7 is formed at the joint of the valve body 1 and the valve cover 6, the valve seat 6 is arranged in the valve seat mounting groove 7, the valve seat 6 forms an included angle of 60 degrees with the axis of the valve body 1, the valve body 1 and the valve cover 2 are fastened and clamp the valve seat 6 through bolts 5, the sealing between the valve seat and the valve body and the valve cover is guaranteed, a gasket 8 can be further arranged in the valve seat mounting groove 7, and the tightness between the valve seat and the valve cover is further enhanced. The end of the valve clack 4 is provided with a valve clack seat 9 for contacting and sealing with the valve seat 6, and the valve clack seat 9 is detachably connected with the valve clack 4. In this embodiment, the end of the valve clack 4 is provided with a ring groove 41 for installing the valve clack seat 9, the ring groove 41 is provided with a pressing plate 10 and a screw 11, the ring groove 41 locates the installation position of the valve clack seat 9, the pressing plate 10 compresses the valve clack seat 9 and fixes the valve clack 4, the screw 11 fastens the valve clack seat 9 and the valve clack 4, the structure is firm, the disassembly is convenient, the replacement is convenient, and other detachable modes can be adopted to fix the valve clack seat, such as clamping, joggling and the like. In the opening and closing process of the valve clack 4, only the valve clack seat 9 is in contact with the valve seat 6, and the valve clack seat 9 can be replaced after being worn, so that the whole check valve is not required to be replaced, and the cost is saved.
