Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a three-way regulating valve. Background Technology

[0002] Valves are used for fluid control, ranging from the simplest gate valves to the various valves used in highly complex automated control systems. Their types and specifications are quite diverse. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. Valves are also classified according to their materials, such as cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and custom-made non-standard valves. They are widely used in industries such as petroleum, chemical, power, water treatment, pharmaceuticals, and food.

[0003] In industrial production processes, it is often necessary to transport a material to different locations and to precisely control the material's discharge direction and flow rate. Existing three-way valves have certain limitations in structural design and functional implementation, and cannot meet complex production needs. Among them, existing three-way regulating valves cannot flexibly adjust the material distribution ratio during use, or, due to unreasonable structure, the gate plate may wear out severely during long-term use, which can easily affect the valve's service life and control accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a three-way regulating valve that combines the stability of a flat gate valve with the high-efficiency driving capability of an electro-hydraulic actuator, ensuring stable and reliable valve operation and thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-way regulating valve, including a main frame, a feeding box fixedly connected to the top surface of the main frame, and a feeding port opened at the middle position of the top surface of the feeding box; a double-cylinder electro-hydraulic actuator fixedly installed on one side surface of the main frame, and a gate fixedly connected inside the feeding box at the output end of the double-cylinder electro-hydraulic actuator; the moving positions of the gate include: position one, position two, and position three; a feeding box provided on the bottom surface of the main frame, and a discharge port one provided on one side of the bottom surface of the feeding box; and a discharge port two provided on the side of the bottom surface of the feeding box adjacent to the discharge port one.

[0006] Preferably, the main frame is made of channel steel.

[0007] Preferably, a guide roller is installed below the gate inside the feeding box, and multiple guide rollers are provided, which are evenly distributed below the gate.

[0008] Preferably, the gate is matched with the feeding box.

[0009] Preferably, the gates correspond to positions one, two, and three, respectively.

[0010] Preferably, the unloading box is fixedly welded to the main frame, and the loading box is fixedly welded to the main frame.

[0011] Preferably, the feed inlet is located at the middle of the top surface of the feeding box, and the discharge outlet one and discharge outlet two are evenly distributed on both sides of the bottom surface of the feeding box.

[0012] Compared with the prior art, the present invention provides a three-way regulating valve, which has the following advantages:

[0013] (1) In this utility model, the three-way regulating valve can be used for a material with two discharge positions, and can realize the switching of discharge direction and control of material flow. When it is necessary to discharge from discharge port one, the gate is moved to position one by controlling the double-cylinder electro-hydraulic push rod. At this time, discharge port one is open and discharge port two is closed, and all material is discharged from discharge port one. When it is necessary to switch to discharge port two, the gate is moved to position two by controlling the double-cylinder electro-hydraulic push rod. At this time, discharge port one is closed and discharge port two is open, and all material is discharged from discharge port two. If it is necessary to discharge from discharge port one and discharge port two at the same time and adjust the material distribution ratio, the gate is moved to position three by controlling the double-cylinder electro-hydraulic push rod. Material can be discharged from discharge port one and discharge port two at the same time. The material distribution ratio can be changed by adjusting the gate opening. The material distribution ratio can be adjusted according to the gate opening, so as to meet different production needs.

[0014] (2) In this utility model, the main frame is made of channel steel. Channel steel has high strength and stability, which can ensure that the valve is structurally firm during long-term use. At the same time, since different application scenarios require different valve sizes, detailed dimensions will be designed separately according to different specifications to ensure that the valve can adapt to various working conditions. When the gate advance stroke is large, in order to reduce friction between the gate and the frame and reduce wear, small guide rollers can be added at the bottom. In addition, a protective structure is set between the gate and the frame to further extend the overall service life of the valve. Attached Figure Description

[0023] Please refer to Figure 1-3A three-way regulating valve includes a main frame 1. A feeding box 9 is fixedly connected to the top surface of the main frame 1, and a feed inlet 2 is located in the middle of the top surface of the feeding box 9. A double-cylinder electro-hydraulic actuator 4 is fixedly installed on one side surface of the main frame 1, and a gate 3 is fixedly connected inside the feeding box 9 at the output end of the double-cylinder electro-hydraulic actuator 4. The gate 3 has three movable positions: position one 6, position two 7, and position three 8. A feeding box 5 is located on the bottom surface of the main frame 1, and a discharge port one 10 is located on one side of the bottom surface of the feeding box 5. A discharge port two 11 is located on the side of the discharge port one 10 on the bottom surface of the feeding box 5. The main frame 1 is made of channel steel of appropriate size according to different specifications. When installing the dual-cylinder electro-hydraulic actuator 4, ensure it is securely installed and reliably connected, capable of driving the gate 3 to move normally. Install the gate 3 according to design requirements, and determine whether small guide rollers are needed based on the gate 3's advance stroke. After installation, debug the electrical components to ensure they can accurately control the position of the gate 3 and achieve different working states. When switching to discharge port 10, control the dual-cylinder electro-hydraulic actuator 4 to move the gate 3 to position 6, at which point discharge port 10 is open and discharge port 21 is closed. When switching to discharge port 21, control the dual-cylinder electro-hydraulic actuator 4 to drive the gate 3 to position 7, achieving a change in discharge direction. If discharge is to be made simultaneously from discharge port 10 and discharge port 21, and the material distribution ratio is adjusted, control the dual-cylinder electro-hydraulic actuator 4 to move the gate 3 to position 8. The material distribution ratio is changed by adjusting the opening of the gate 3. The material distribution ratio can be adjusted according to the opening of the gate 3 to meet different production needs.

[0024] In one embodiment, the main frame 1 is made of channel steel, which has high strength and stability, ensuring the valve's structural integrity during long-term use. Meanwhile, since different application scenarios require different valve dimensions, detailed dimensions are designed individually for each specification to ensure the valve can adapt to various working conditions.

[0025] In one embodiment, a guide roller is installed below the gate 3 inside the feed box 9. There are multiple guide rollers, which are evenly distributed below the gate 3. When the gate 3 has a large pushing stroke, in order to reduce the friction between the gate 3 and the main frame 1 and reduce wear, the guide rollers are added at the bottom, which can slow down the wear and further extend the service life of the valve.

[0026] In one embodiment, the gate 3 is matched with the feeding box 9, which allows the gate 3 to move within the feeding box 9.

[0027] In one embodiment, the gate 3 corresponds to position 6, position 7, and position 8 respectively. When it is necessary to switch to discharge port 10, the gate 3 is moved to position 6 by controlling the double-cylinder electro-hydraulic actuator 4. At this time, discharge port 10 is open and discharge port 21 is closed. When it is necessary to switch to discharge port 21, the double-cylinder electro-hydraulic actuator 4 drives the gate 3 to position 7 to realize the switching of discharge direction. If it is necessary to discharge from both discharge port 10 and discharge port 21 at the same time and adjust the distribution ratio, the double-cylinder electro-hydraulic actuator 4 is controlled to move the gate 3 to position 8. The distribution ratio is changed by adjusting the opening of the gate 3. The distribution ratio can be adjusted according to the opening of the gate 3 to meet different production needs.

[0028] In one embodiment, the unloading box 5 is fixedly welded to the main frame 1, and the loading box 9 is fixedly welded to the main frame 1, which can maintain the sturdiness between the loading box 9, the main frame 1 and the unloading box 5.

[0029] In one embodiment, the feed inlet 2 is located at the middle of the top surface of the feeding box 9, and the discharge outlet 10 and discharge outlet 21 are evenly distributed on both sides of the bottom surface of the feeding box 5. The feed inlet 2 can be used to add materials into the feeding box 9, and the discharge outlet 10 and discharge outlet 21 can be used to discharge materials respectively.

[0030] In one embodiment, a protective cover is provided between the gate 3 and the main frame 1, wherein the protective cover and guide rollers between the gate 3 and the main frame 1 can effectively reduce wear and ensure the stable operation of the gate 3.

[0031] Working principle:

[0032] In use, firstly, select appropriate-sized channel steel to construct the main frame 1 according to different specifications. When installing the double-cylinder electro-hydraulic actuator 4, ensure that it is firmly installed, reliably connected, and can normally drive the gate 3 to move. Install the gate 3 according to the design requirements, and determine whether small guide rollers need to be installed based on the advancement stroke of the gate 3. After installation, debug the electrical components to ensure that they can accurately control the position of the gate 3 and achieve different working states. When it is necessary to switch to discharge port 10, control the double-cylinder electro-hydraulic actuator 4 to move the gate 3 to position 6. At this time, discharge port 10 is open and discharge port 21 is closed. When it is necessary to switch to discharge port 21, control the double-cylinder electro-hydraulic actuator 4 to drive the gate 3 to position 7 to achieve the switching of discharge direction. If it is necessary to discharge from discharge port 10 at the same time... The material is discharged from outlet 11, and the material distribution ratio is adjusted. Then, the double-cylinder electro-hydraulic push rod 4 is controlled to move the gate 3 to position 8. The material distribution ratio is changed by adjusting the opening of the gate 3. The material distribution ratio can be adjusted according to the opening of the gate 3 to meet different production needs. During the whole working process, the protective structure between the gate 3 and the frame support and the guide roller can effectively reduce wear and ensure the stable operation of the gate 3.
