Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a filter-locking integrated valve. Background Art

[0002] The lock valve is a valve device with a very high utilization rate and safety factor. The lock valve can be used to control the on and off of the liquid in the pipeline, and effectively control the heating and water supply. After the control is blocked, the lock valve has the function of being closed and cannot be opened at will without destruction.

[0003] In order to prevent the pipeline from being blocked by impurities and the impurities attached to the valve core affecting the opening and closing, the existing lock valve generally has a filter component at the water inlet end of the valve. Although the setting of the filter component can solve the problems of the pipeline being blocked by impurities and the impurities attached to the valve core affecting the opening and closing, the existing filter component does not have the self-cleaning function. The staff needs to clean the filter component frequently, and the cleaning frequency is relatively high. In view of this, the present utility model is specially proposed. Utility Model Content

[0006] In order to improve the stability of the filter plate during rotation, further, a plurality of first T-blocks are equidistantly fixedly connected to the position where the filter plate and the filter housing are attached, and a first T-shaped slot used in conjunction with the first T-block is provided in the filter housing.

[0007] In order to prevent the filter plate from being blocked too quickly, the filter plate is further configured to be conical.

[0008] In order to facilitate more thorough cleaning of the filter plate, further, the rotating rod is connected with a movable plate by a reciprocating thread, and a self-resetting water bag ring is fixedly connected to the side of the movable plate close to the filter plate, and the self-resetting water bag ring is arranged on the rotating rod, and a circle of water spray heads are equidistantly connected to the side of the self-resetting water bag ring close to the filter plate, and a circle of water inlets are equidistantly provided on the side of the self-resetting water bag ring close to the movable plate, and a one-way valve is respectively provided in the water spray heads and the water inlets on the self-resetting water bag ring, and a guide rod is symmetrically fixedly connected to the side of the movable plate away from the filter plate, and the guide rod is slidably connected to the adjacent support rod, and an extrusion plate used in conjunction with the self-resetting water bag ring is connected to the position of the rotating rod close to the filter plate.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3 A filter-lock integrated valve comprises a valve body 1, and also comprises: a filter housing 2, which is mounted at the water inlet end of the valve body 1, and the filter housing 2 and the valve body 1 are detachably connected via threads; a support rod 3, which is symmetrically fixedly connected in the filter housing 2; a rotating rod 301, which is rotatably connected to the two support rods 3; an impeller assembly 302, which is fixedly connected to one end of the rotating rod 301 away from the valve body 1; a filter plate 303, which is fixedly connected to the rotating rod 301 and is located between the two support rods 3, and an outer circle of the filter plate 303 is sealed and slidably attached to the inner wall of the filter housing 2.

[0021] When in use, the staff first connects and fixes the two ends of the valve to the adjacent ends of the two water pipes respectively. When water needs to be transported, the valve core in the valve body 1 can be opened, and then the water flow in the water pipe will flow through the filter housing 2 and the valve body 1 to the other water pipe. When the water flows in the filter housing 2, the impurities in the water will be intercepted by the filter plate 303, so as to facilitate the filtration of impurities in the water and avoid the valve in the valve body 1 being blocked by impurities, affecting the use of the valve. At the same time, when the water flows through the filter housing 2, the impeller group 302 will rotate under the impact of the water flow, and then the impeller group 302 will drive the rotating rod 301 to rotate, and the rotating rod 301 will drive the filter plate 303 to rotate, and then the filter plate 303 attached to the filter plate 303 will rotate. The impurities will be thrown outwards under the action of the centrifugal force of the filter plate 303, so that the impurities on the filter plate 303 are easily separated, ensuring the rate of water flowing through the filter plate 303. By arranging a filter housing 2 at the water inlet end of the valve body 1, and arranging an impeller group 302, a rotating rod 301, and a filter plate 303 in the filter housing 2, when the water flows, not only can the impurities in the water be intercepted and filtered out, and the valve core in the valve body 1 is prevented from being blocked by impurities and affecting normal opening and closing, but the impact of the water flow can also be used to drive the filter plate 303 to rotate, so that the impurities attached to the filter plate 303 leave the filter plate 303 under the action of centrifugal force, ensuring the flow rate of the water flow, and at the same time, the frequency of cleaning the filter plate 303 can be reduced, reducing the labor of the staff for cleaning the filter plate 303.

[0022] Embodiment 2:

[0023] Reference Figure 1-Figure 3 , a filter locking integrated valve, which is basically the same as Example 1, and further: a plurality of first T-blocks 304 are equidistantly fixedly connected to the position where the filter plate 303 is attached to the filter housing 2, and a first T-shaped slide groove used in conjunction with the first T-block 304 is provided in the filter housing 2. Through the cooperation of the first T-block 304 and the first T-shaped slide groove, when the filter plate 303 rotates, the stability of the filter plate 303 can be further improved, thereby preventing the filter plate 303 from being affected by the instability of the filter plate 303 and affecting the rotation rate of the filter plate 303.

[0024] The filter plate 303 is set in a cone shape, which can increase the overall area of ​​the filter plate 303. Since the filter surface of the filter plate 303 is set inclined, the filter plate 303 can be prevented from being quickly blocked by impurities in the water, and the frequency of cleaning the filter plate 303 is effectively reduced.

[0025] A movable plate 305 is connected to the rotating rod 301 through a reciprocating thread, and a self-resetting water bag circle 306 is fixedly connected to the side of the movable plate 305 close to the filter plate 303, and the self-resetting water bag circle 306 is sleeved on the rotating rod 301. A circle of water spray heads are equidistantly connected to the side of the self-resetting water bag circle 306 close to the filter plate 303, and a circle of water inlets are equidistantly provided on the side of the self-resetting water bag circle 306 close to the movable plate 305. Check valves are respectively provided in the water spray heads and the water inlets on the self-resetting water bag circle 306, and a guide rod 307 is symmetrically fixedly connected to the side of the movable plate 305 away from the filter plate 303. The guide rod 307 is slidably connected to the adjacent support rod 3, and the position of the rotating rod 301 close to the filter plate 303 is connected to the self-resetting water bag circle 306. The resetting water bag circle 306 is used in conjunction with the extrusion plate 308. When the rotating rod 301 rotates, the rotating rod 301 will drive the movable plate 305 to reciprocate in the filter housing 2 under the cooperation of the reciprocating thread and the guide rod 307, and the movable plate 305 will drive the self-resetting water bag circle 306 to reciprocate. When the self-resetting water bag circle 306 and the extrusion plate 308 are squeezed against each other, the water in the self-resetting water bag circle 306 will be sprayed out through the water spray head, and then the water sprayed through the water spray head will reversely impact the filter plate 303, thereby impacting the block impurities stuck in the filter holes of the filter plate 303, causing the block impurities to fall off the filter plate 303, further improving the impurity removal efficiency of the filter plate 303.

[0026] The extrusion plate 308 is rotatably connected to the rotating rod 301, and a plurality of second T-blocks 309 are fixedly connected to the inner wall of the extrusion plate 308. The rotating rod 301 is provided with a second T-shaped slide groove used in conjunction with the second T-block 309. By making the extrusion plate 308 rotatably connected to the rotating rod 301 through the second T-block 309, when the self-resetting water bag ring 306 and the extrusion plate 308 are extruded, the extrusion plate 308 can be prevented from rotating together with the rotating rod 301, thereby causing friction between the extrusion plate 308 and the self-resetting water bag ring 306, causing wear on the self-resetting water bag ring 306, and affecting the service life of the self-resetting water bag ring 306.

[0027] A circle of annular protrusions 201 are provided on one side of the filter housing 2 close to the valve body 1. The annular protrusions 201 and the water inlet end of the valve body 1 are sealed together via a sealing ring 202. By cooperating with the annular protrusions 201 and the sealing ring 202, when the filter housing 2 is connected to the valve body 1 through threads, the sealing ring 202 can be squeezed by the annular protrusions 201, thereby ensuring the sealing between the filter housing 2 and the valve body 1 and avoiding water leakage.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
