[0002] When drilling in oil fields, plunger pumps are often used to extract high-pressure fluids. In order to ensure the reverse flow of the fluid, a valve body assembly is required. The valve body assembly is a one-way valve, generally composed of a valve outer shell, and an internal valve ball and valve ball seat. When the fluid passes through the valve body, the valve ball leaves the valve ball seat, the flow channel opens, and the fluid can pass through. When the fluid flows in the opposite direction, the valve ball sits on the valve ball seat under the action of pressure, the flow channel is closed, and the fluid cannot pass through the valve body.
[0003] When the existing valve assembly for oil field drilling is used, the valve spring inside the valve outer shell and the connection between the valve ball and the valve ball seat are used to ensure that the fluid can only pass in one direction.
