Embodiment
[0014] Such as figure 1 As shown, it includes valve head 1, valve disc 2, and valve claw 3. The valve head 1 and valve disc 2 are integrally structured and made by forging, which is a forging; the valve claw 3 is made by casting, which is a casting. There is a welding layer 4 between the valve disc 2 and the valve claw 3, that is, the valve disc 2 and the valve claw 3 are fixed by welding.

The invention discloses a valve body manufacturing method and relates to a valve body. The valve body comprises a valve head, a valve disc and a valve jaw, and is characterized in that the valve head and the valve disc have an integral structure; a welding layer is arranged between the valve disc and the valve jaw; the valve head and the valve disc are forgings; and the valve jaw is a casting. The valve body has the beneficial effects that different parts of the valve body are subjected to different treatment methods, namely the valve head and the valve disc have the integral structure and are manufactured by adopting a forging method, namely the valve head and the valve disc are forgings; and moreover, the valve claw is manufactured by adopting a casting method, namely the valve claw is a casting and is fixedly welded, so that the quality and efficiency can be both considered.
Description
technical field [0001] The present invention relates to the technical field of machinery, and further relates to a valve, especially a valve body. Background technique [0002] At present, the valve body of the liquid valve, including the valve head, valve disc, and valve claw, is usually produced by casting method due to production efficiency and cost. Under the action of higher pressure, its sealing effect will be affected. If the entire valve body is made by forging, this problem can be effectively solved. However, due to the low working efficiency of forging, especially the difficult operation of valve claw forging, it affects the production efficiency of enterprises. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a method for manufacturing a valve body, which adopts different processing methods for different parts of the valve body, so that both quality and efficiency can be taken into a...
