One -way valve has straight -through type and right angle type. Straight -through type one -way valve is installed on the pipeline by screw connection. Right angle type one -way valve has screw connection, plate connection and flange connection three forms.

[0003] At present, the liquid inlet end and the liquid outlet end of the high pressure pump will be installed with one -way valve, to ensure that the liquid can pass through the one -way valve of the water inlet end when the high pressure pump pumps liquid, and then, the liquid is discharged through the one -way valve of the liquid outlet end of the high pressure pump, to prevent the liquid from backflowing when pumping and discharging.

[0004] Because, the current one -way valve is composed of valve flap, valve body and spring and other important structures, with the long -term use of one -way valve, the spring inside the valve body is repeatedly stretched and compressed, so that the spring is prone to softening, leading to the gradual loss of elasticity of the spring, so that the spring cannot drive the valve flap to reset and seal the inside of the valve body, and the valve body is prone to leak, at this time, the staff needs to take down the one -way valve from the high pressure pump, and then replace the whole one -way valve, thereby increasing the maintenance cost.
