Problems solved by technology

There is currently no specific production process for the main valve body used to control the excavator grab. The valve body is designed to be produced in separate parts, but the sealing performance is not good when assembled and used, and it is easy to leak, but the overall production structure design cannot be well formed by the flow channel.

Description

technical field [0001] The invention relates to the field of a valve body, in particular to a main valve body for excavator grab control. Background technique [0002] Valve body, English: valve body. It is a main component of the valve; there are different mechanical manufacturing methods according to the pressure level. For example: casting, forging, etc. There is currently no specific production process for the main valve body used for excavator grab control. The valve body is designed for separate production, but the sealing performance is not good for assembly and use, and it is easy to leak, but the overall production structure design cannot be well formed by the flow channel. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a main valve body for excavator grab control, which is compact in design and easy to produce. [0004] Technical scheme of the present invention: [0005] The main valve body for excavator...
