Abstract
The utility model discloses a kind of novel current stabilization Lift check valve, comprise valve body, in the center hole of valve inner, be fixed with valve shaft, spring housing is contained on valve shaft, on valve body, there are fluid input and fluid output, fluid input and fluid output separate by sealing gasket, and valve plate and gland are equipped with in sealing gasket both sides.Due to sealing gasket circumference indentation structure, in the time that fluid passes through from sealing gasket, fluid is by its laciniation shunting guiding, and can not rebounded by valve plate or stop, cause turbulent flow, convection cell has good guiding function, effectively prevents turbulent generation, reduce the destruction of turbulent flow to water meter, ensured accuracy and the working life of water meter.
Description
Technical field
The utility model relates to valve technology field, especially a kind of novel current stabilization Lift check valve.
Background technique
Safety check is the valve that can automatically stop fluid to flow backwards, its flap is opened under fluid pressure action, fluid flows to outlet side from suction side, and when suction side pressure is during lower than outlet side, flap automatically closes to prevent that fluid from flowing backwards under the acting in conjunction of the factor such as fluid pressure difference, spring force.When fluid is when the flap, because circulation area tightens and the impact of valve inner structure, easily cause fluid to occur turbulent flow, directly affect the accuracy of meter reading and shorten water meter working life, in addition, turbulent vibration and the noise that also can cause pipeline.Market existing lifting straight-through type soft-sealing check valve all can not effectively solve fluid by time the turbulent problem that produces.
Model utility content
The purpose of this utility model is to provide a kind of good airproof performance and can prevents the novel current stabilization Lift check valve of fluid turbulence.
For achieving the above object, the utility model adopts following technical proposals:
Novel current stabilization Lift check valve, comprise valve body, in the center hole of valve inner, be fixed with valve shaft, spring housing is contained on valve shaft, on valve body, there are fluid input and fluid output, fluid input and fluid output separate by sealing gasket, sealing gasket excircle indentation structure, and valve plate and gland are equipped with in sealing gasket both sides.
On valve shaft, have screw thread, valve plate and gland are sleeved on valve shaft and by screw thread to be fixed, and sealing gasket is sleeved on valve shaft, is pressed between valve plate and gland.
Sealing gasket by spring compression on valve body sealing surface.
The beneficial effect that the utility model brings is: fluid is from fluid input enters valve body, and sealing gasket, under the effect of hydrodynamic pressure, drives valve shaft to move upward in center hole, sealing gasket moves upward, depart from valve body, fluid flows out by subgasket edges, flows to fluid output; After fluid is cut off, because valve plate is subject to the effect of spring force, drive valve shaft to move downward in center hole, sealing gasket is pressed on valve body again, get back to sealing station, prevent leakage and the refluence of fluid.In addition, due to sealing gasket circumference indentation structure, in the time that fluid passes through from sealing gasket, fluid is guided by its laciniation shunting, and can not rebounded by valve plate or stop, causes turbulent flow, convection cell has good guiding function, effectively prevent turbulent generation, reduced the destruction of turbulent flow to water meter, ensured accuracy and the working life of water meter.

Embodiment
Novel current stabilization Lift check valve as shown in figures 1 and 3, comprise valve body 1, in the center hole 7 of valve body 1 inside, be fixed with valve shaft 2, spring 6 is sleeved on valve shaft 2, on valve body 1, there are fluid input 8 and fluid output 9, fluid input 8 and fluid output 9 separate by sealing gasket 4, sealing gasket 4 excircle indentation structures, and valve plate 5 and gland 3 are equipped with in sealing gasket 4 both sides.On valve shaft 2, have screw thread, valve plate 5 and gland 3 are sleeved on valve shaft 2 and by screw thread to be fixed, and sealing gasket 4 is sleeved on valve shaft 2, is pressed between valve plate 5 and gland 3, and sealing gasket 4 is pressed on the sealing surface of valve body 1 by spring 6.
As shown in Figure 2, when fluid is from fluid input 8 enters valve body 1, sealing gasket 4 is under the effect of hydrodynamic pressure, drive valve shaft 2 to move upward in center hole 7, thereby sealing gasket 4 is moved upward, depart from valve body 1, fluid flows out by sealing gasket 4 edges, flows to fluid output 9; After fluid is cut off, because valve plate 5 is subject to the effect of spring 6 elastic force, drive valve shaft 2 to move downward in center hole 7, sealing gasket 4 is pressed on the sealing surface of valve body 1 again, get back to sealing station, prevent leakage and the refluence of fluid.
As shown in Figure 3, due to sealing gasket 4 circumference indentation structures, in the time that fluid passes through from sealing gasket 4 edges, fluid is guided by its laciniation shunting, and can not rebounded or stop by valve plate 5, causes turbulent flow, convection cell has good guiding function, effectively prevent turbulent generation, reduced the destruction of turbulent flow to water meter, ensured accuracy and the working life of water meter.
