Description

Technical Field

[0001] This utility model relates to a three-way reversing valve, belonging to the field of slurry conveying technology. Background Technology

[0002] Three-way directional valves are used in the field of slurry transportation to solve the problem of automatic switching between dual pumps and dual pipelines in mines. The existing patent, with publication number CN201810817U, entitled "A Three-Way Automatic Directional Valve," suffers from problems such as poor ball sealing, easy track damage, manufacturing difficulties, and shortened lifespan in practical applications. Therefore, there is an urgent need for a three-way directional valve with good sealing performance, easy manufacturing, and long service life to replace the aforementioned product. The disadvantages of existing technology are as follows: 1. The rubber seals at the first and second inlets of the three-way directional valve are artificially bonded, making it difficult to ensure a perfect fit with the ball. Gaps easily form between the rubber and the ball, leading to slurry leakage. As the slurry wears down the rubber, the gaps widen, becoming difficult to repair after wear, ultimately causing the three-way directional valve to malfunction and shortening its lifespan. 2. The raceway of the three-way directional valve is subjected to the rolling pressure of the ball for a long time, causing the guide rubber to easily fail and the rubber body to break. This allows the slurry to erode the skeleton, causing slurry leakage and shortening the lifespan. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing a three-way reversing valve. The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A three-way reversing valve includes an upper valve body, a ball, and a lower valve body. The upper valve body is provided with a movable guide rail and a discharge port. The lower valve body is provided with two inlets, and the inlets are provided with sealing blocks that match the contact surface of the ball.

[0004] Furthermore, the sealing block includes a spherical skeleton, on which spherical colloids are disposed.

[0005] Furthermore, the spherical skeleton and the spherical colloid are integrally molded.

[0006] Furthermore, the sealing block and the lower valve body are detachably connected by nut A and bolt A.

[0007] Furthermore, the movable guide rail includes a frame, on which a colloid B is disposed.

[0008] Furthermore, the skeleton and the colloid B are integrally molded.

[0009] Furthermore, the movable guide rail is detachably connected to the upper valve body via bolt B and nut B.

[0010] Furthermore, the inner surfaces of both the upper and lower valve bodies are coated with a gel-like substance.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This application replaces the fixed guide rail with a replaceable movable guide rail, reducing the predicament of the entire valve failing due to guide rail damage, extending the service life, and improving the valve manufacturing precision.

[0012] 2. The ball and the feed inlet of this application adopt replaceable sealing blocks, which effectively solves the problem of slurry leakage caused by poor ball sealing, ensuring sealing performance and extending product service life; the sealing block and the lower valve body adopt detachable connection, which solves the predicament of having to replace the whole valve after manual bonding cannot guarantee the shape and the sealing part is worn, which greatly extends the service life of the three-way reversing valve.

[0013] 3. This application shortens the manufacturing time of the three-way directional valve and extends its service life by 3-5 times, thereby improving economic efficiency. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1-2As shown, a three-way directional valve includes an upper valve body 1, a ball 4, and a lower valve body 2. The upper valve body 1 has a movable guide rail 3 and a discharge port 6. The lower valve body 2 has two inlets 5, and each inlet 5 has a sealing block 8 that matches the contact surface of the ball 4. The movable guide rail 3 reduces the risk of valve failure due to guide rail damage, extending service life and improving valve manufacturing precision. The sealing block 8 at the inlet 5, matching the contact surface of the ball 4, ensures uniform fit between the sealing block 8 and the ball 4, effectively solving the problem of leakage caused by incomplete ball sealing, ensuring sealing performance and extending product service life. The sealing block 8 is detachably connected to the lower valve body 2, solving the problem of inconsistent shape due to manual bonding and the need to replace the entire valve after wear at the seal, greatly extending the service life of the three-way directional valve. This shortens the manufacturing time of the three-way directional valve, extends its service life by 3-5 times, and improves economic efficiency.

[0021] The sealing block 8 includes a spherical skeleton with a spherical colloid on it. The spherical skeleton and the spherical colloid are integrally molded. The sealing block 8 is detachably connected to the lower valve body 2 via a nut A9 and a bolt A10. A sealing block 8 is installed at the feed inlet 5. The sealing block 8 is a non-standard part, manufactured by molding the spherical skeleton and the spherical colloid using a mold. The contact surface between the sealing block 8 and the ball 4 is made using a mold that matches the spherical surface of the ball 4, greatly improving the fit between the sealing block 8 and the ball 4. The sealing block 8 is connected to the lower valve body 2 via a nut A9 and a bolt A10. When the sealing block 8 is severely worn, the nut A9 and bolt A10 can be removed to replace it with a new sealing block 8, which can greatly extend the service life of the three-way directional valve and shorten its manufacturing cycle.

[0022] The movable guide rail 3 includes a frame 31, on which a colloid B 32 is disposed. The frame 31 and the colloid B 32 are integrally molded. The movable guide rail 3 is detachably connected to the upper valve body 1 by bolts B 33 and nuts B 34. The movable guide rail 3 and the upper valve body 1 are connected by bolts B 33 and nuts B 34. This application eliminates the need for the guide rail sealing block used in the prior art. Figure 3-4 As shown, this effectively saves materials. Damaged movable guide rail 3 can be replaced promptly, greatly extending the service life of the three-way directional valve.

[0023] The inner surfaces of both the upper valve body 1 and the lower valve body 2 are coated with colloid A 7.

[0024] This application replaces the fixed guide rail with a replaceable movable guide rail 3, reducing the predicament of the entire valve failing due to guide rail damage, extending service life, and improving valve manufacturing precision; the ball 4 and the feed inlet 5 use replaceable sealing blocks 8, effectively solving the problem of slurry leakage caused by incomplete ball sealing, ensuring sealing performance and extending product service life; the sealing block 8 and the lower valve body 2 are detachably connected, solving the predicament of being forced to replace the entire valve after manual bonding cannot guarantee the shape and the sealing point is worn, greatly extending the service life of the three-way reversing valve.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
