Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Referring to fig. 1-2, a plate-type wafer check valve comprises a valve body 1, a valve clack 2 is arranged in the valve body 1, a rocker 3 is arranged on one side of the valve clack 2, the end of the rocker 3 is rotatably connected with the valve body 1 through a pin shaft 9, and a hanging ring 11 is arranged at the top of the valve body 1.
In this embodiment, as shown in fig. 1, the inner side wall of the water inlet 12 of the valve body 1 is inclined, that is, the valve flap 2 is attached to the inner side wall of the water inlet 12 when closed, and is also in an inclined state.
In one embodiment, as shown in fig. 2, the end of the pin 9 is provided with a plug screw 7 and a sealing gasket 8 for fixing the pin 9.
In this embodiment, the valve body 1 is provided with a hole for inserting the pin 9 (the outer end of the hole is provided with a thread adapted to the plug screw 7), after the pin 9 is inserted, the pin is fixed in the hole by the plug screw 7, and the sealing gasket 8 is sleeved on the pin 9 before the plug screw 7 is sleeved.
Furthermore, a threaded hole is formed in the end portion of the rocker 3, and a threaded column matched with the threaded hole is arranged at the joint of the valve clack 2 and the rocker 3. The end part of the threaded column penetrating through the threaded hole in the rocker 3 is sleeved with a buffer gasket 4, and one side of the buffer gasket 4 is provided with a tightening nut 10 for fastening the valve clack 2 on the rocker 3. One side of the split nut 10 is provided with a cotter pin 5 to prevent the split nut 10 from loosening. As shown in fig. 1, the cotter 5 is provided at the side of the split nut 10.
In some embodiments, a limit hole may be formed at an end of the threaded post, and the cotter pin 5 may be inserted through the limit hole.
As shown in fig. 2, a gasket 6 is sleeved at the joint of the pin shaft 9 and the rocker 3.
As shown in fig. 1, the outer wall of the valve body 1 has a concave cross section, which is convenient for punching, installing and fixing the valve body 1.
The valve clack 2 is made of surfacing wear-resistant alloy, is corrosion-resistant and impact-resistant, and ensures the service life of the valve.
The working principle is as follows: as shown in fig. 1, when the medium flows along the flow direction arrow, the valve flap 2 is pushed by the medium pressure medium and rotates around the pin 9 through the rocker 3, so that the valve is opened. When the medium flows backwards, the rocker 3 rotates around the pin shaft 9 under the pressure of the medium and the weight of the valve clack 2, the valve is closed, the medium is prevented from flowing backwards and leaking, and the equipment and the pipeline are prevented from being damaged by the backflow medium.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
