Abstract
The utility model relates to a damping wear resisting non-return valve, which belongs to the technical field of valves. The utility model is composed of a valve body, a reset spring, a valve seat, a valve rod, a valve plug, a needle plug, etc., wherein, the valve plug, the valve rod and the reset spring are loaded in the valve body from an outlet of the valve body and is arranged on the valve seat, and then the valve seat is arranged on the outlet of the valve body. A damping chamber is arranged between the valve rod and the valve seat, the lower end of the damping chamber is provided with the damping adjustment pin plug, and the lower end of the needle plug is provided with a locking nut for regulating the up-and-down movement of the needle plug. An O-shaped sealing ring is respectively additionally arranged between the valve seat and the valve rod, and the sealing surfaces of the valve body and the valve plug. Because the technical proposal is used, the utility model has the advantages of damp, wear resistance, no impact, long life, and zero leakage; the effect is good through tryout.
Description
(1) technical field: the utility model relates to valve technology field, the wear-resisting safety check of particularly a kind of damping.
(2) background technique: flow backwards for preventing the liquid material, in to use Lift check valve in the small-bore pipeline very common.But this valve opens and closes undamped, therefore impacts big, life-span weak point, can not realize long lifetime, zero leakage
(3) summary of the invention: the utility model is the above-mentioned technological deficiency that overcomes existing Lift check valve, the technical solution of being taked is: to the Lift check valve that is made of valve body, valve seat, Returnning spring, valve rod and valve plug etc., between valve rod and valve seat, set up dampening chamber, have damping metering needle plug in dampening chamber, open and close impact thereby reduce Lift check valve; On the sealing surface of valve plug, between valve seat and valve rod, respectively set up O-ring seals at the valve body seam, form double sealing structure whereby, can make this valve realize that at≤200 ℃ the long lifetives do not have leakage.
Owing to take above-mentioned technical solution, the beneficial effects of the utility model to be that damping is wear-resisting, do not have and impact, the long lifetime, zero leakage, splendid through trial effect.
(4) description of drawings: Fig. 1 is a structural representation of the present utility model.
(5) embodiment:, elaborate a kind of optimal way of the present utility model below in conjunction with accompanying drawing.Referring to Fig. 1 as can be known, the utility model mainly is made of with valve plug 7, pin plug 9 etc. valve body 1, Returnning spring 2, valve seat 3, valve rod 5, valve plug 7 exports pack valve body 1 in together with Returnning spring 2 by valve body 1 with valve rod 5 and is installed on the valve seat 3, and valve seat 3 is installed in valve body 1 outlet again.Be provided with dampening chamber 8 at valve rod 5 and 3 of valve seats, dampening chamber 8 lower ends are provided with damping metering needle plug 9, and locking nut 10 is equipped with in the lower end of pin plug 9, are used for the upper and lower displacement of metering needle plug 9.On the sealing surface of 5 of valve rods, valve body 1 and valve plug 7, respectively set up O-ring seals (4,6) at valve seat 3.
Working principle: the utility model is installed on the fluid circuit, holds when medium flows to B by the A end, and valve plug 7 overcomes Returnning spring 2 under pressure medium active force moves down, i.e. valve opening.In this process, valve plug 7 is slowly opened under the damping mechanism effect that valve rod 5, valve seat 3 and pin plug 9 constitute, and does not promptly have impact.The opening speed of valve plug 7 can be by the adjusting down control of pin plug 9 with locking nut 10.When medium was held to A end adverse current by B, valve plug 7 first speed under Returnning spring 2 and pressure medium effect was closed, and Slow Close is realized in the back under the damping mechanism effect, thereby realizes the check function.Under O RunddichtringO (4,6) effect, this valve can be realized zero leakage.
Claims (1)
1, the wear-resisting safety check of a kind of damping is mainly by valve body (1), Returnning spring (2), valve seat (3), valve rod (5) and valve plug (7), pin plug formations such as (9), it is characterized in that valve plug (7) and valve rod (5) pack in the valve body (1) together with Returnning spring (2) by valve body (1) outlet and be installed on the valve seat (3), valve seat (3) is installed in valve body (1) outlet again; Be provided with dampening chamber (8) between valve rod (5) and valve seat (3), be provided with damping metering needle plug (9) in dampening chamber (8) lower end, locking nut (10) is equipped with in the lower end of pin plug (9); With between valve rod (5), on the sealing surface of valve body (1) and valve plug (7), respectively set up O-ring seals (4,6) at valve seat (3).
