Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically a three-way valve with bidirectional check function. Background Technology

[0002] Tees, also known as pipe tees or tee fittings, are primarily used to change the direction of fluid flow, placed where a branch pipe needs to be inserted into the main channel. They can be classified according to pipe diameter and are generally made of materials such as carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-bonded asphalt, and PVC.

[0003] In current three-way valves, the valve disc is driven by an electronic control system to achieve the sealing and blocking of the secondary channel and the opening of the channel. The precise fit between the valve disc and the inner wall of the secondary channel is crucial to the backflow blocking effect, which can easily lead to backflow problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a three-way valve with a bidirectional check function. This solves the problem mentioned in the background art: in the process of the current three-way valve driving the valve disc through the electronic control system to achieve the sealing and blocking of the secondary channel and the opening of the channel, the precise fit between the valve disc and the inner wall of the secondary channel is crucial to the backflow blocking effect, which easily leads to backflow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-way valve with bidirectional check function, comprising a main body, the outer surface of which is fixedly connected to two secondary channels and a main channel, an electrically controlled valve body is provided on the outer surface of the main body, a control display is electrically connected to the outer surface of the electrically controlled valve body, a wire is fixedly installed at the output end of the control display, a servo motor is fixedly installed at the output end of the wire, a fixed roller is fixedly installed at the output end of the servo motor, a check element is fixedly installed on the outer surface of the fixed roller, the check element is rotatably connected to the secondary channels, a valve disc is fixedly installed on the outer surface of the check element, and the check element is sealed to the secondary channels through the valve disc.

[0006] Preferably, the outer surface of the main channel is provided with a second connecting flange, and a filter screen is fixedly installed on the main channel through the second connecting flange. The outer surfaces of the two secondary channels are each provided with a first connecting flange, and a connector is fixedly installed on the outer surface of the connector through the first connecting flange. A guide fan is fixedly installed on the outer surface of the connector.

[0007] Preferably, both the No. 1 connecting flange and the No. 2 connecting flange are provided with connecting pipes, and sealing gaskets are provided at the junctions of the No. 1 connecting flange and the connecting pipes.

[0009] Preferably, the control display is equipped with a pressure balance sensor, an electric actuator, and a flow regulating valve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This three-way valve with bidirectional check function receives control signals through the electronically controlled valve body and converts them into drive commands via the control display. The commands are transmitted to the servo motor via wires. The servo motor outputs power to drive the fixed roller to rotate. The fixed roller synchronously drives the check element to rotate, so that the valve disc on the outer surface of the check element precisely fits or disengages from the inner wall of the secondary channel. When it is necessary to block the fluid in a certain direction, the servo motor drives the check element on the corresponding side to rotate, and the valve disc forms a sealed connection with the secondary channel to prevent the fluid from flowing back. This achieves automated adjustment of the check state and improves the convenience and stability of multi-pipe fluid direction control.

[0012] 2. This three-way valve with bidirectional check function has a filter screen fixedly installed at the fluid inlet end via the No. 2 connecting flange in the main channel. When the fluid enters the main channel, the filter screen intercepts and filters particulate impurities in the fluid, preventing impurities from entering the valve body. The two secondary channels are fixedly connected to the connectors via the No. 1 connecting flange. When the fluid flows through the secondary channels, the guide fan on the outer surface of the connector guides the flow pattern with the fluid flow, allowing the fluid to flow smoothly through the secondary channels along a preset trajectory, reducing the generation of local turbulence and eddies. This achieves the sealing and disassembly of each component, facilitating later maintenance and replacement, and further improving the stability and service life of the system.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please refer to Figures 1-4.

[0021] A three-way valve with bidirectional check function includes a main body 1. The outer surface of the main body 1 is fixedly connected to two secondary channels 2 and a main channel 3. An electrically controlled valve body 4 is provided on the outer surface of the main body 1. The outer surface of the electrically controlled valve body 4 is electrically connected to a control display 5. A wire is fixedly installed at the output end of the control display 5. A servo motor 6 is fixedly installed at the output end of the wire. A fixed roller 7 is fixedly installed at the output end of the servo motor 6. A check element 8 is fixedly installed on the outer surface of the fixed roller 7. The check element 8 is rotatably connected to the secondary channels 2. A valve disc 15 is fixedly installed on the outer surface of the check element 8. The check element 8 is sealed to the secondary channels 2 through the valve disc 15.

[0022] Specifically, the control signal is received by the electronically controlled valve body 4 and converted into a drive command by the control display 5. The command is transmitted to the servo motor 6 through the wire. The servo motor 6 outputs power to drive the fixed roller 7 to rotate. The fixed roller 7 synchronously drives the check valve 8 to rotate, so that the valve disc 15 on the outer surface of the check valve 8 precisely fits or disengages from the inner wall of the secondary channel 2. When it is necessary to block the fluid in a certain direction, the servo motor 6 drives the check valve 8 on the corresponding side to rotate, and the valve disc 15 forms a sealed connection with the secondary channel 2 to prevent the fluid from flowing back. When it is necessary to open the channel, the servo motor 6 drives the check valve 8 in the opposite direction, and the valve disc 15 disengages from the sealing surface, so that the fluid can flow along the main channel 3 and the target secondary channel 2.

[0023] In this embodiment, the control display 5 is equipped with a pressure balance sensor, an electric actuator, and a flow regulating valve.

[0024] Specifically, the pressure balance sensor monitors the pressure difference between the main channel 3 and the secondary channel 2 in real time and transmits the pressure signal to the control display 5. After analyzing and processing the signal, the control display 5 sends an adjustment command to the electric actuator. The electric actuator synchronously drives the flow regulating valve and the check valve 8 to operate: when the pressure difference exceeds the set threshold, the electric actuator finely adjusts the opening of the flow regulating valve to balance the fluid pressure, while simultaneously controlling the valve disc 15 of the check valve 8 to remain in a sealed or open state; when the flow needs to be adjusted, the control display 5, based on preset parameters or real-time signals, precisely changes the flow area of ​​the flow regulating valve through the electric actuator to achieve stepless flow regulation. During the adjustment process, the valve disc 15 always maintains a suitable sealed or open state with the secondary channel 2 to maintain the check function.

[0025] Working Principle: Two secondary channels 2 and a main channel 3 are fixedly connected to the outer surface of the main body 1. An electrically controlled valve body 4 is installed on the outer surface of the main body 1, and a control display 5 is electrically connected to the outer surface of the valve body 4. A wire is fixedly installed at the output end of the control display 5, and a servo motor 6 is fixedly installed at the output end of the wire. A fixed roller 7 is fixedly installed at the output end of the servo motor 6. A check valve 8 is fixedly installed on the outer surface of the fixed roller 7. The check valve 8 is rotatably connected to the secondary channel 2, and a valve disc 15 is fixedly installed on the outer surface of the check valve 8. The check valve 8 is sealed to the secondary channel 2 through the valve disc 15. The electrically controlled valve body 4 receives the control signal and converts it into a drive command through the control display 5. The command is transmitted to the servo motor 6 through the wire. The servo motor 6 outputs power to drive the fixed roller 7 to rotate, and the fixed roller 7 synchronously drives the check valve 8 to rotate, so that the valve disc 15 on the outer surface of the check valve 8 precisely fits or disengages from the inner wall of the secondary channel 2. When it is necessary to block the fluid in a certain direction, the servo motor 6 drives the check valve 8 on the corresponding side to rotate, and the valve disc 15 forms a sealed connection with the secondary channel 2 to prevent the fluid from flowing backward. When it is necessary to open the channel, the servo motor 6 drives the check valve 8 in the opposite direction, and the valve disc 15 disengages from the sealing surface, so that the fluid can flow along the main channel 3 and the target secondary channel 2. Compared with related technologies, the three-way valve with bidirectional check function provided by this utility model has the following beneficial effects: it achieves the automatic adjustment of the check state and improves the convenience and stability of multi-pipe fluid direction control.

[0026] Example 2:

[0027] Please refer to Figures 1-4.

[0028] The outer surface of the main channel 3 is provided with a second connecting flange 12. The filter screen 13 is fixedly installed on the main channel 3 through the second connecting flange 12. The outer surface of each of the two secondary channels 2 is provided with a first connecting flange 9. The two secondary channels 2 are fixedly installed with a connector 10 through the first connecting flange 9. The outer surface of the connector 10 is fixedly installed with a guide fan 11.

[0029] Specifically, the filter screen 13 is fixedly installed at the fluid inlet end via the second connecting flange 12 through the main channel 3. When the fluid enters the main channel 3, the filter screen 13 intercepts and filters particulate impurities in the fluid, preventing impurities from entering the valve body. The two secondary channels 2 are fixedly connected to the connecting parts 10 via the first connecting flange 9. When the fluid flows through the secondary channels 2, the guide fan 11 on the outer surface of the connecting parts 10 guides the flow pattern with the fluid flow, so that the fluid flows smoothly through the secondary channels 2 along a preset trajectory, reducing the generation of local turbulence and eddies. This achieves the sealing and disassembly of each component, facilitating later maintenance and replacement, and further improving the stability and service life of the system.

[0030] In the embodiment: both the first connecting flange 9 and the second connecting flange 12 are provided with connecting pipes 14, and sealing gaskets are provided at the junctions of the first connecting flange 9 and the second connecting flange 12 with the connecting pipes 14.

[0031] Specifically, the No. 1 connecting flange 9 is fixed to the secondary channel 2, and the No. 2 connecting flange 12 is fixed to the main channel 3 by fastening structures such as bolts. Their connecting pipe 14 provides a flow channel for fluid. At the junction of the flange and the connecting pipe 14, the sealing gasket undergoes elastic deformation under the action of the flange fastening force, filling the micro gaps on the contact surface and forming a physical sealing barrier. When the fluid flows in the pipe, the flange connection structure resists the axial force generated by the fluid pressure, ensuring a stable connection between the pipe and the valve body. The sealing gasket also compensates for unevenness of the contact surface through deformation, blocking the path of fluid leakage from the flange gap.

[0032] In the embodiment: the guide fan 11 is made of a main shaft and a plurality of guide fan blades 11. The plurality of guide fan blades 11 are all made of a waterproof material, and the plurality of guide fan blades 11 are arranged in a circular array.

[0033] Specifically, when the fluid flows through the connector 10 of the secondary channel 2, it impacts several circumferential array guide fan blades 11 supported by the main shaft. The fan blades rotate around the main shaft under the action of fluid thrust. The circumferentially symmetrically distributed structure guides the fluid to form a spiral orderly flow field, reducing the turbulence disturbance of the fluid at pipe bends or merging points. At the same time, the guide fan blades 11 are made of a waterproof stain-resistant material. Its surface properties make it difficult for water vapor and impurities in the fluid to be adsorbed and remain, avoiding scale buildup on the fan blade surface.

[0034] Working principle: A second connecting flange 12 is provided on the outer surface of the main channel 3. A filter screen 13 is fixedly installed in the main channel 3 through the second connecting flange 12. At the same time, a first connecting flange 9 is provided on the outer surface of each of the two auxiliary channels 2. A connector 10 is fixedly installed in each of the two auxiliary channels 2 through the first connecting flange 9. A guide fan 11 is fixedly installed on the outer surface of the connector 10. The filter screen 13 is fixedly installed at the fluid inlet end of the main channel 3 through the second connecting flange 12. When the fluid enters the main channel 3, the filter screen 13 intercepts and filters particulate impurities in the fluid, preventing... To prevent impurities from entering the valve body; the two secondary channels 2 are fixedly connected to the connecting piece 10 via the first connecting flange 9. When the fluid flows through the secondary channels 2, the guide fan 11 on the outer surface of the connecting piece 10 guides the flow pattern with the fluid flow, so that the fluid flows smoothly through the secondary channels 2 along the preset trajectory, reducing the generation of local turbulence and eddies. Compared with related technologies, the three-way valve with bidirectional check function provided by this utility model has the following beneficial effects: thereby achieving the sealing and disassembly of each component installation, facilitating later maintenance and replacement, and further improving the stability and service life of the system operation.
