Abstract

The invention relates to the field of quantitative pump one-way valves, in particular to a damping type valve flexible plastic valve. The damping type valve flexible plastic valve comprises valve blocks and valve cores which are in an interlocking structure with the valve blocks, and further comprises alignment devices and sealing devices arranged at the joints of the valve blocks and the valve cores; the valve cores are movably sleeve the valve blocks after being aligned by the alignment devices; liquid outlet channels used for discharging liquid are formed in the valve cores; and the valve blocks abut against the liquid outlet channels through the sealing devices to enable the liquid outlet channels to form seals. According to the damping type valve flexible plastic valve, through face-to-face sealing of the valve blocks to the valve cores, compared with an existing plastic spring valve structure, the deformation amount during injection molding is relatively small, the part control requirement is reduced so that leakage caused by part deformation can be reduced, and the reject ratio is reduced, in addition, when a material body is thickened, the structure can also play a good sealing role, and an existing ball valve and a spring valve are effectively replaced, and therefore the risk of damage and corrosion is reduced.

Description

technical field [0001] The invention relates to the field of one-way valves of quantitative pumps, in particular to a flexible plastic valve with a damping valve. Background technique [0002] In the existing quantitative pump products, a one-way valve is arranged at the bottom of the cylinder body, and the discharge of the liquid is controlled through the one-way valve. [0003] At present, ball valves and spring valves are mainly used in one-way valves. Among them, the ball valve structure uses the self-weight of the ball to make the ball itself contact with the cylinder to achieve sealing. The ball moves up and down during use. , can not play the role of instant sealing when pressing, it will produce reverse spray, which will affect the instability of the output, especially this structure completely relies on the self-weight of the sphere to work, when the material body is sticky, the sphere will be stuck and cannot be reset Doing the seal renders the entire pump useless...
