Abstract

Provided is a piston pump exhaust structure. A piston pump comprises a hydraulic cylinder, a piston and a liquid inlet one-way valve connected with the hydraulic cylinder. The piston pump further comprises a liquid outlet one-way valve communicating with the hydraulic cylinder; the liquid outlet one-way valve comprises a liquid outlet valve seat, a sealing ring, a needle valve and a spring; the sealing ring, the needle valve and the spring are installed in the liquid outlet valve seat; the sealing ring is installed between the liquid outlet valve seat and the needle valve; the spring is installed on the needle valve; and a liquid outlet is formed in the upper portion of the liquid outlet valve seat. The piston pump exhaust structure has the advantages that discharged liquid does not carry gas, liquid is discharged smoothly, and the use effect is good.

Description

technical field [0001] The invention relates to an elastic fluid pump, relates to the setting of a valve, in particular to a piston pump exhaust structure. Background technique [0002] A liquid tank is installed in the soap dispenser, the liquid tank is connected to the liquid inlet check valve, the liquid inlet check valve is connected to the liquid inlet to the hydraulic cylinder, the hydraulic cylinder is connected to the outlet, the outlet is connected to the liquid outlet check valve, and the liquid outlet check valve is controlled by Driven by the piston of the hydraulic cylinder, the soap liquid in the hydraulic cylinder is discharged through the liquid outlet of the liquid outlet check valve. The liquid discharge structure of the prior art will contain gas in the discharge liquid, which affects its use effect and the liquid discharge is not smooth. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the object of the present invention ...
