Abstract
The utility model provides an anechoic check valve which consists of a valve body, a valve clack and a spring, wherein the inner cavity of the valve body is approximately in the shape of ellipsoid; the valve clack is in the shape of bowl; a water inlet of the valve body is fixedly provided with a guide bracket; the periphery of the water inlet side of the valve clack and the inner end face of the guide bracket are formed into a contact sealing surface; the water inlet side and the water outlet side of the valve clack are respectively provided with a shaft; and each shaft is respectively penetrated through a support hole in the guide bracket and a guide hole at the water outlet of the valve body. The sealing surface with the inclined angle of 45 degrees is arranged between the periphery of the water inlet side of the valve clack and the inner end face of the guide bracket. The sealing surface is internally provided with an O-shaped sealing ring. As the valve body is approximately in the shape of ellipsoid, and the inner cavity of the valve body forms into the natural streamline type, the anechoic check valve reduces the structure of sharp turn and sharp convex, thereby reducing the noise of hydraulic resistance, and reducing the flowing and eroding noise and the energy loss caused by the sudden expansion and contraction of the liquid; and as the valve clack is in the shape of bowl, the anechoic check valve reduces the turbulent flow, and reduces the loss and the noise of the flow resistance. The anechoic check valve is simple in structure, convenient to assemble and disassemble, and easy to maintain.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to valve, particularly a kind of damping check valve.
Background technique:
In the prior art, be provided with a flat board perpendicular to fluid in the valve body of damping check valve, this flat board has increased the resistance of gear fluid.If diameter valve is big more, the flap basal area is also big more, the resistance that block current this moment is also big more, fluid rushes at dull and stereotyped meeting and produces turbulent flow, eddy current greatly, fluid resistance and noise are all increased greatly, and existing valve body structure is provided with unreasonable, wherein has the structure of area sudden change, therefore cause stream erosion noise, and increase the energy loss of fluid.
Summary of the invention:
The purpose of this utility model is to provide a kind of damping check valve, and described this damping check valve will solve the technical problem that the damping check valve fluid resistance is big in the prior art, noise is big.
This damping check valve of the present utility model is by valve body, flap and spring constitute, described flap is arranged in the runner of valve body, flap is connected with one first sliding axle at its water outlet side, valve body is provided with a pilot hole in water outlet, described first sliding axle is arranged in the described pilot hole, described spring is arranged on first sliding axle, and between flap and pilot hole, wherein, the inner chamber of described valve body is approximate elliposoidal, described flap is bowl-type, the water outlet place of valve body is set with a leading truck, and the middle part of described leading truck is provided with a bearing hole, and the influent side of flap is connected with one second sliding axle, described second sliding axle is arranged in the described bearing hole, and the periphery of flap influent side contacts with the interior edge face of leading truck.
Further, described leading truck is connected with described valve body by screw thread.
Further, be provided with the sealing surface at 45 degree inclination angles between the interior edge face of the periphery of flap influent side and leading truck.
Further, be provided with O-ring seals in the surface of contact of the inner of the periphery of flap influent side and leading truck.
Working principle of the present utility model is: flap is subjected to the thrust of spring, is close at ordinary times on the sealing surface of leading truck, guarantees that medium can not flow backwards.When the thrust of flowing medium is worth greater than certain, just can push flap open, the pressure spring flow ipe.During dismounting if from after take off and the friction tight leading truck of valve body, spring and flap just can withdraw from.Valve body is made approximate elliposoidal, and body cavity has formed the streamlined of nature like this, has reduced the sharp turn, point is protruding, thereby has reduced fluid resistance and noise, has so also reduced unexpected expansion of fluid and sudden contraction and the stream that produces loses noise and energy loss.It is bowl-shape that flap design becomes, and reduced turbulent flow, and the resistance to water-flow loss is significantly reduced, and also significantly reduced noise.After cutout, the active force of spring is closed flap rapidly.Along with closing of valve, the flow channel area dwindles rapidly, has increased the resistance that fluid flows backwards, thereby has reduced the refluence speed of fluid.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model adopts the valve body that is approximate elliposoidal in damping check valve, body cavity has formed the streamlined of nature, reduce sharp turn, sharp male structure, thereby reduced fluid resistance and noise, also reduced unexpected expansion of fluid and sudden contraction and the stream that produces erosion noise and energy loss; It is bowl-shape that flap design becomes, and reduced turbulent flow, and the resistance to water-flow loss is significantly reduced, and also significantly reduced noise; The utility model is simple in structure simultaneously, easy disassembly, for ease of maintenaince.
Description of drawings:
Fig. 1 is the structural representation of damping check valve of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, damping check valve of the present utility model, by valve body 1, flap 4 and spring 5 constitute, described flap 4 is arranged in the runner of valve body 1, flap 4 is connected with one first sliding axle at its water outlet side, valve body 1 is provided with a pilot hole in water outlet, described first sliding axle is arranged in the described pilot hole, described spring 5 is arranged on first sliding axle, and between flap 4 and pilot hole, wherein, the inner chamber of described valve body 1 is approximate elliposoidal, described flap 4 is bowl-type, the water outlet place of valve body 1 is set with a leading truck 2, and the middle part of described leading truck 2 is provided with a bearing hole, and the influent side of flap 4 is connected with one second sliding axle, described second sliding axle is arranged in the described bearing hole, and the periphery of flap 4 influent sides contacts with the interior edge face of leading truck 2.
Further, described leading truck 2 is connected with described valve body 1 by screw thread.
Further, be provided with the sealing surface at 45 degree inclination angles between the interior edge face of the periphery of flap 4 influent sides and leading truck 2.
Further, be provided with O-ring seals 3 in the surface of contact of the inner of the periphery of flap 4 influent sides and leading truck 2.
The working procedure of present embodiment is: the direction of arrow is represented water (flow) direction among Fig. 1.Flap 4 is subjected to the thrust of spring 5, is close at ordinary times on the sealing surface of leading truck 2, guarantees that medium can not flow backwards.When the thrust of flowing medium is worth greater than certain, just can push flap 4 open, pressure spring 5 flow ipes.During dismounting if from after take off and valve body 1 friction tight leading truck 2, spring 5 and flap 4 just can withdraw from.Valve body 1 is made approximate elliposoidal, and valve body 1 inner chamber has formed the streamlined of nature like this, has reduced the sharp turn, point is protruding, thereby has reduced fluid resistance and noise, has so also reduced unexpected expansion of fluid and sudden contraction and the stream that produces loses noise and energy loss.Flap 4 is designed to bowl-shape, has reduced turbulent flow, and the resistance to water-flow loss is significantly reduced, and has also significantly reduced noise.After cutout, the active force of spring 5 is closed flap 4 rapidly.Along with closing of valve, the flow channel area dwindles rapidly, has increased the resistance that fluid flows backwards, thereby has reduced the refluence speed of fluid.
