A kind of spring is slow opens quick-closure check valve, comprise valve body, flap, lengthening valve shaft, valve shaft connecting rod, draw high spring, spring pedestal, valve body is provided with flow pass and flow channel, flap is provided with between flow channel and flow pass, flap is provided with connecting rod, and the connecting rod the other end and valve body are tightly fixed; Connecting rod is provided with square through hole, lengthens valve shaft centre and tightly fixes through square through hole and connecting rod; Described lengthening valve shaft through valve body, lengthens valve shaft two ends exposed outside valve body respectively, lengthening valve shaft with the surface of contact of valve body on be respectively equipped with seal ring; The two ends lengthening valve shaft are respectively equipped with valve shaft connecting rod; the valve shaft connecting rod the other end is provided with tinsel, and tinsel connects and draws high spring, the described center line drawing high spring and flow pass is perpendicular; drawing high the spring the other end is fixed on spring pedestal, draws high spring outer ring and is surrounded by rubber protective ring.The utility model can realize slow changing up and close function, and structure is simple, and cost of production is low, easy to maintenance.
Description
Technical field:
The utility model relates to a kind of safety check, particularly relates to that a kind of spring is slow opens quick-closure check valve.
Background technique:
Safety check is a kind of equipment preventing pipeline medium from flowing backwards, and has a wide range of applications in production and processing.In existing safety check, the safety check of oil hydraulic cylinder pattern uses comparatively extensive, and it has slow opening and closing, eliminates water hammer function, but but cannot realize quick closedown, and the ability of prevention water hammer, brings great inconvenience to user.
Model utility content:
For the deficiencies in the prior art, the utility model devises that a kind of spring is slow opens quick-closure check valve, comprises valve body, flap, lengthening valve shaft, valve shaft connecting rod, draws high spring, spring pedestal.
The technical solution adopted for the present invention to solve the technical problems is: valve body is provided with flow pass and flow channel, is provided with flap between flow channel and flow pass, and flap is provided with connecting rod, and the connecting rod the other end and valve body are tightly fixed; Connecting rod is provided with square through hole, lengthens valve shaft centre and tightly fixes through square through hole and connecting rod; Described lengthening valve shaft through valve body, lengthens valve shaft two ends exposed outside valve body respectively, lengthening valve shaft with the surface of contact of valve body on be respectively equipped with seal ring; The two ends lengthening valve shaft are respectively equipped with valve shaft connecting rod; the valve shaft connecting rod the other end is provided with tinsel, and tinsel connects and draws high spring, the described center line drawing high spring and flow pass is perpendicular; drawing high the spring the other end is fixed on spring pedestal, draws high spring outer ring and is surrounded by rubber protective ring.
The beneficial effects of the utility model: can realize slow changing up and close function, structure is simple, and cost of production is low, easy to maintenance.
Accompanying drawing illustrates:
Fig. 1 is general check valve structure figure;
Fig. 2 is the utility model plan view;
Fig. 3 is the utility model side view;
Wherein, 1-flap, 2-lengthens valve shaft, 3-valve shaft connecting rod, and 4-draws high spring, 5-spring pedestal.
Embodiment:
For the deficiencies in the prior art, the utility model devises that a kind of spring is slow opens quick-closure check valve, comprises valve body 1, flap, lengthening valve shaft 2, valve shaft connecting rod 3, draws high spring 4, spring pedestal 5.
The technical solution adopted for the present invention to solve the technical problems is: valve body is provided with flow pass and flow channel, is provided with flap 1 between flow channel and flow pass, and flap 1 is provided with connecting rod, and the connecting rod the other end and valve body are tightly fixed; Connecting rod is provided with square through hole, lengthens valve shaft centre and tightly fixes through square through hole and connecting rod; Described lengthening valve shaft 2, through valve body, lengthens valve shaft 2 two ends exposed outside valve body respectively, lengthening valve shaft 2 with the surface of contact of valve body on be respectively equipped with seal ring; The two ends lengthening valve shaft 2 are respectively equipped with valve shaft connecting rod 3; the valve shaft connecting rod the other end is provided with tinsel; tinsel connects and draws high spring 4; the described center line drawing high spring 4 and flow pass is perpendicular; draw high spring 4 the other end to be fixed on spring pedestal 5, draw high spring outer ring and be surrounded by rubber protective ring.
The utility model drives lengthening valve shaft to rotate when flap carries out breakdown action, lengthen valve shaft and drive valve shaft link rotatable, and the high spring that pulls of valve shaft connecting rod afterbody platform produces reaction force, flap opening force is increased, realizes slowly opening.When flap needs to carry out closing motion, draw high spring contraction power and drive lengthening valve shaft to rotate by valve shaft connecting rod, make flap carry out closing motion, flap is at self gravitation simultaneously, and pressure medium, to flap back side active force, carries out quick closedown under triple role power.
