Description

Technical Field

[0001] The utility model relates to the technical field of distributing valves, in particular to a three-way distributing valve. Background Art

[0002] A three-way distributing valve is a device used to control the rapid reversal of material flow in material conveying systems. It is widely used to convey solid particles and powdered materials in industries such as building materials, metallurgy, mining, light industry, and grain. During operation, the actuating handle automatically or manually drives the valve shaft and valve plate to swing at a certain angle, thereby controlling the flow direction and distributing the material.

[0003] The valve plate in the prior art is a straight plate structure, and the surface of the valve plate that receives the impact of the circulating material is flat. When the material falls, it hits the valve plate plane and is then introduced into one side of the pipe. The material has a significant impact on the valve plate and causes the valve plate to wear; the materials collide with each other, limiting the material's descending speed and efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide a three-way material dispensing valve in order to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A three-way material distributing valve comprises a three-way valve body; a valve plate is rotatably mounted in the three-way valve body; and both sides of the valve plate have first arc-shaped surfaces for receiving materials.

[0007] Furthermore, it includes two lining plates, which are respectively located on both sides of the valve plate, and the first arc-shaped surface is located on the outer side of the lining plate.

[0008] Furthermore, the lining plate is connected to the valve plate by bolts.

[0009] Furthermore, the valve plate is provided with a weight-reducing hole.

[0010] Furthermore, a second arcuate surface is provided at the end of the valve plate away from the rotation point, and a third arcuate surface matching the second arcuate surface is provided on the inner side of the three-way valve body.

[0011] Furthermore, the three-way valve body is provided with an arcuate groove portion, the arcuate groove portion opening toward the inside of the three-way valve body; the end of the valve plate near its rotation point is provided with a fourth arcuate surface that cooperates with the inner side of the arcuate groove portion.

[0012] Furthermore, one end of the valve plate is connected to a valve shaft, which is rotatably connected to the three-way valve body; one end of the valve shaft extends out of the three-way valve body and is connected to a driving handle.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The valve plate of the utility model has first curved surfaces on both sides. When distributing materials to both sides, the first curved surfaces can reduce the impact of powder materials on the valve plate, effectively guide and buffer the impact, reduce wear on the valve plate, and protect the materials due to the reduced interaction force. Compared with valve plates with flat surfaces that receive materials, the mutual impact of materials after contacting the valve plate is reduced, which has little impact on material conveying efficiency.

[0015] The utility model adopts a detachable lining plate connected by bolts. The lining plate is arranged on the outer side of the valve plate and directly contacts the material. It can be easily replaced after wear and damage. The arc groove portion of the utility model can support the end of the valve plate and limit the valve plate in both directions at the same time.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0021] In the description of this utility model, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "provided with" and "provided with" should be understood in a broad sense. For example, the object "provided with" may be a part of the main body, or may be arranged separately from the main body and connected to the main body. The connection may be detachable or non-detachable. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] The present invention is further described in detail below with reference to the embodiments.

[0024] The specific embodiment of the three-way distributing valve provided by the utility model is as follows:

[0025] See also Figure 1-3 The three-way distributing valve comprises a three-way valve body 1; the three-way valve body 1 has three ports, one of which is for feeding materials into the valve, and the other two are for discharging materials out of the valve. Square flanges are provided at the three ports for easy connection with external pipelines.

[0026] The valve plate 2 is rotatably installed in the three-way valve body 1; one end of the valve plate 2 is connected to the valve shaft 11, the valve shaft 11 passes through the end of the valve plate 2 and is fixedly connected to the valve plate 2, and the valve shaft 11 is rotatably connected to the three-way valve body 1; one end of the valve shaft 11 extends to the outside of the three-way valve body 1 and is connected to a driving handle 12.

[0027] Manually rotating the driving handle 12 can rotate the valve shaft 11 and the valve plate 2 in the three-way valve body 1, thereby changing the angle of the valve plate 2, so that the feed port is connected to the two discharge ports respectively, thereby achieving the purpose of controlling the flow direction of the material and distributing the material.

[0028] In some other embodiments, an automatic telescopic rod, such as an electric telescopic rod or a start-up telescopic rod, may be added; the telescopic end of the automatic telescopic rod is connected to the end of the driving handle 12 away from the valve shaft 11, and the automatic movement of the valve plate 2 is achieved through the movement of the automatic telescopic rod.

[0029] Both sides of the valve plate 2 have a first curved surface 3 for receiving the material; the first curved surface 3 is an inner concave surface. In this embodiment, both sides of the valve plate 2 are connected with lining plates 4 by bolts 5. There are two lining plates 4, and the lining plates 4 cover the side surfaces of the valve plate 2; the first curved surface 3 is located on the outer side surface of the lining plate 4.

[0030] In this embodiment, the liner 4 comprises an integrally connected flat plate portion and an arcuate plate portion. The outer side of the arcuate plate portion forms the first arcuate surface 3. One end of the first arcuate surface 3 corresponds to the inner sidewall of the feed port, and the other end smoothly connects to the flat surface of the flat plate portion. The lower end of the outer side of the flat plate portion corresponds to the inner sidewall of the discharge port. In other embodiments, the liner 4 may be a monolithic arcuate plate without the flat plate portion.

[0031] The first curved surface 3 reduces the impact of the material and guides and cushions the material, reducing the material's impact on the liner 4 and, in turn, the impact on the material itself. The first curved surface 3 optimizes the flow path of the powder material, reduces resistance, and allows some material to change direction more consistently after impacting the liner 4, reducing the mutual impact of the material impacting the liner 4 and thus minimizing the impact on material conveying efficiency.

[0032] In this embodiment, the bolt 5 has a hexagonal head. The liner 4 has a stepped hole that mates with the bolt 5, preventing the bolt 5 head from protruding. The valve plate 2 also has an internally threaded hole that mates with the bolt 5. If the liner 4 wears or becomes damaged, the bolt 5 can be removed and replaced, eliminating the tedious process of completely dismantling the valve plate 2. In this embodiment, the liner 4 is made of manganese steel, which offers excellent wear resistance.

[0033] Since the lining plates 4 on both sides of the valve plate 2 have a first arcuate surface 3, the thickness of the valve plate 2 at the end away from the rotation portion increases; in order to avoid the valve plate 2 being too heavy, in this embodiment, a weight-reducing hole 6 is provided on the valve plate 2 to effectively reduce the weight of the valve plate 2.

[0034] A second curved surface 7 is provided on the end of the valve plate 2, away from its rotational position. A third curved surface 8 is provided on the inner side of the three-way valve body 1 to mate with the second curved surface 7. Because the valve plate 2 has two static positions, in this embodiment, two third curved surfaces 8 are provided, one located at the junction of the inner end of the two discharge port side walls and the feed port side walls. The second curved surface 7 is convex, while the third curved surface 8 is concave, which does not interfere with the rotation of the valve plate 2. The second curved surface 7 can mate with the two third curved surfaces 8, ensuring sufficient material distribution and reducing material leakage into the closed discharge port.

[0035] The three-way valve body 1 is provided with an arcuate groove 9, which opens toward the inside of the three-way valve body 1. The arcuate groove 9 is integrally connected to the side wall of the three-way valve body 1, specifically at the junction of the two discharge port side walls. The arcuate groove 9 has a semicircular cross-section, and the end of the valve plate 2 near its rotation point is provided with a fourth arcuate surface 10 that cooperates with the inside of the arcuate groove 9. The fourth arcuate surface 10 fits in contact with the inside of the arcuate groove 9 to reduce material leakage from this point to the closed discharge port. The two side edges of the arcuate groove 9 with a semicircular cross-section can also limit the valve plate 2, and the outer side edges of the arcuate groove 9 can be supported on the side of the valve plate 2. Specifically, the side edges of the arcuate groove 9 are in contact with the liner 4, respectively supporting the valve plate 2 in two discharge states.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
