Abstract
The utility model relates to a fluid control valve, and provides a no-wear ball check valve. According to the no-wear ball check valve, the structure is simple, a ball blocking valve core is not deformed after long term use, the backflow of medium can be effectively prevented, the sealing performance is good, the on and off are flexible and the noise is low. The no-wear ball check valve comprises a valve body with a hollow containing cavity and the ball blocking valve core, wherein the valve body is provided with a water inlet and a water outlet which are communicated with medium; the water inlet is provided with a valve cover; the valve cover is provided with a valve opening, and the inner diameter of the valve opening is less than the ball blocking valve core; the inner wall of the valve body is also uniformly distributed with guide ribs which are used for controlling the ball blocking valve core to do linear sliding along the circumferential direction; the ball blocking valve core can be arranged in the valve body in a manner of performing linear repeated sliding movement along the guide ribs in the valve body, and is in clutching connection with the valve opening of the valve cover; and the outer surface of the ball blocking valve core is wrapped with an elastic layer.
Description
Technical field
The utility model relates to a kind of fluid control valve, and is particularly a kind of without the wearing and tearing ball check valve.
Background technique
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in the pipeline from flowing backwards, and is widely used in the fluid line.
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in the pipeline from flowing backwards.Safety check is divided by structure, can be divided into three kinds on Lift check valve, Swing check valve, butterfly check valve and spherical plugging type safety check.It is most widely used general wherein to belong to spherical plugging type safety check, existing spherical plugging type safety check mainly comprises valve body and the spherical shutoff spool with hollow reservoir, described valve body vertically part is provided with feed-water end and the waterexit end that is connected with pipeline, described valve inleting water end is provided with water intake, described water intake is provided with valve gap, described valve gap is provided with internal diameter less than the valve port of spherical shutoff spool, the waterexit end of described valve body is provided with internal diameter less than the water outlet of spherical shutoff spool, but described spherical shutoff spool straight line is being located in the valve body of slippage repeatedly, but and be connected with the valve port clutch of described valve gap, usually in order to control the accurately slippage in valve body of spherical shutoff spool, described valve interior wall is controlled the guiding rib that spherical shutoff spool is done the straight line slippage along circumferentially also being evenly equipped with, during work, spherical shutoff spool can break away from valve port under the forward of medium promotes pass through medium smoothly, will push spherical shutoff spool to valve port when medium oppositely promotes closes valve body, thereby block medium fluid, the shutoff spool of above-mentioned safety check is that hard material is made, spherical shutoff spool and valve port generation friction can cause spherical shutoff spool distortion or wearing and tearing in the opening-closing process, affect sealing effect, can't guarantee not refluxing fully of medium, the non-return effect is bad, the working life of spherical shutoff spool is short, and when the spherical shutoff spool that hard material is made contacts with the valve port keying, the noise that produces is large, and opening-closing process is not soft.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of shutoff spool simple in structure, spherical long-term use indeformable, can effectively prevent medium refluence, good seal performance, keying is soft, noise is low without the wearing and tearing ball check valve.
For solving this technical problem, the utility model is taked following scheme: a kind of without the wearing and tearing ball check valve, comprise valve body and spherical shutoff spool with hollow reservoir, described valve body has water intake and the water outlet that connects medium, described water intake is provided with valve gap, offer internal diameter on the described valve gap less than the valve port of spherical shutoff spool, described valve interior wall is controlled the guiding rib that spherical shutoff spool is done the straight line slippage along circumferentially also being evenly equipped with, described spherical shutoff spool can be done repeatedly being located in the valve body of slippage of straight line along guiding rib in the valve body, but and be connected with the valve port clutch of described valve gap, the outer surface of described spherical shutoff spool is coated with one deck elasitic layer.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this is novel without the wearing and tearing ball check valve, the outer surface of spherical shutoff spool is coated with one deck elasitic layer, can allow the long-term use of spherical plugging valve core indeformable, size keeps steady state, non-return is effective, prolonged the working life of spherical shutoff spool, elastic ball shutoff spool opens and closes with valve port can reduce vibration when contacting, the noise that produces is little, and opening-closing process is soft, this novel without in the using process of wearing and tearing ball check valve substantially without wearing and tearing, corrosion-resistant and the life-span is long, be widely used in building, house drainage, oil, chemical industry, control gold, the pipe-line systems such as boats and ships.
