Technical Field
[0001] This utility model relates to the technical field of electronic two-way water valves, and in particular to a novel electronic two-way water valve. Background Technology
[0002] Currently, with the improvement of people's living standards, private cars have become an indispensable means of transportation for most families. However, oil is a non-renewable energy source, and new energy vehicles are gradually becoming the mainstream means of transportation. Now, the development of new energy vehicles has entered a bottleneck period. Problems such as battery depletion, rapid power loss, and low battery utilization in winter have become the primary challenges to be overcome. There is an urgent need for a new type of device to keep the motor battery in a suitable temperature environment and achieve effective heat utilization. An electronic water valve is an electrically driven valve that controls the flow rate, direction, and pressure of water. The vehicle collects the real-time temperature of the electronically controlled battery, analyzes the battery's thermal demand, and adjusts the flow distribution of each pipeline by driving the column valve / butterfly valve, thereby solving the problem of effective heat utilization.
[0003] Current two-way electronic water valves typically use a pair of magnets mounted on a motor shaft. A Hall sensor on the circuit board detects the change in magnetic poles as the magnets rotate, thereby determining the motor's motion state and controlling its operation. The valve core is driven to rotate via a gear train, resulting in different opening ratios at the outlet to control the flow and pressure in the pipeline. The minimum rotation step of the motor controlled by this two-way electronic water valve is 1 / 2 turn. After being driven by the gear train, the minimum rotation step of the valve core is relatively large. When the flow and pressure in the pipeline are high, the flow and pressure distributed in the pipeline after the valve core rotates cannot meet more precise requirements.
[0004] To address the above issues, an intelligent, high-precision flow control two-way electronic water valve is provided. It can precisely control the flow rate and pressure in the corresponding pipelines, and can also finely distribute heat in the corresponding pipelines to ensure that each thermal management system is in optimal working condition. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a novel electronic two-way water valve that controls the flow and pressure of a pipeline by driving the internal rotation of the valve body structure through an actuator, and can precisely regulate the flow and pressure in the pipeline when the flow and pressure in the pipeline are large.
[0006] This utility model discloses a novel electronic two-way water valve, comprising a valve body structure and an actuator. The valve body is connected to the actuator, and the opening and closing of the valve body is controlled by the actuator. The actuator drives the internal rotation of the valve body structure to control the flow and pressure of the pipeline, enabling precise adjustment of the flow and pressure in the pipeline when the flow and pressure are large.
[0007] Preferably, the valve body structure includes a liquid passage, a valve body, a valve cover, a valve cover sealing ring, a valve core, a valve body sealing gasket, a valve body bottom sealing ring, and a screw sleeve. A sealing groove is provided at the bottom of the valve body, and the valve body bottom sealing ring is adapted to the sealing groove. A protrusion is provided on the valve body bottom sealing ring, and the protrusion on the valve body bottom sealing ring is interference-fitted into the valve body sealing groove.

A limiting groove is provided at the bottom of the valve core, and a stop is provided at the bottom of the valve body, the stop being inserted into the limiting groove of the valve core. Figure 4 As shown, a valve cover sealing ring is provided between the valve cover and the valve core; as Figure 4 As shown, the valve cover sealing ring is placed at the valve cover slot sealing point, the valve cover passes through the valve core, and the valve cover is assembled with the valve body. The screw sleeves are respectively installed at the three holes of the valve body base; the two liquid channels of the valve body are at a 90-degree angle, and the valve core is at a 180-degree angle. The valve core angle is greater than the sum of the angles of the two water inlets and the angles formed by the two water inlets. A sealing groove is provided at the bottom of the valve body, and the sealing ring at the bottom of the valve body is adapted to the sealing groove. The protrusion on the sealing ring at the bottom of the valve body is interference-fitted with the groove at the bottom of the valve body. The valve body and the valve cover are assembled and connected by laser welding. As the valve core rotates, the two sets of liquid channels on the valve body gradually change from being completely disconnected to being completely connected. The flow rate between the two sets of liquid channels is adjusted and controlled by the change in the rotation angle of the valve core. The protrusion on the side of the sealing ring at the bottom of the valve body is interference-fitted with the groove at the bottom of the valve body to prevent it from falling off and to seal the outside of the valve body. The flow rate is controlled by rotating the valve core. The valve body and the valve cover are connected by laser welding to ensure that the coolant inside the valve body will not overflow from the valve cover installation point, ensuring the airtightness of the valve body and improving the practicality of the device.
[0008] Preferably, the actuator includes a screw, an upper housing, a gear set, a worm gear, a magnetic ring, a motor, a PCB board, an actuator sealing ring, a lower housing, a metal bushing, and a motor shaft. The valve cover, magnetic ring, and motor are press-fitted together to form a motor semi-assembly. The magnetic ring is press-fitted onto the motor shaft at the tail of the motor via the metal bushing. The lower housing and gear shaft are injection molded as one piece. The PCB board is soldered into the lower housing. The actuator sealing ring is installed in the sealing ring placement groove within the lower housing. The gear set is installed on the upper end face of the actuator sealing ring, and the gear set presses against the actuator sealing ring to achieve a sealing effect. The upper housing and lower housing are connected and fixed by laser welding after assembly. A worm gear is fitted onto the output end of the motor semi-assembly, and the worm gear meshes with the gear set. The upper housing and lower housing are connected and fixed by laser welding to ensure good internal airtightness of the actuator. The magnetic ring is press-fitted onto the motor shaft at the tail of the motor to ensure that the motor rotation drives the magnetic ring to rotate, thereby sensing changes in magnetic poles through Hall effect.
[0009] Preferably, the connection structure includes a set of output gears in the gear set, a valve core spline on the valve core, the output gears and the valve core spline engaging with each other, and the lower housing being locked to the valve body with screws; through the engagement of the output gears and the valve core spline, the power output by the actuator is transmitted to the valve body structure, thereby driving the valve body structure to regulate the liquid flow, improving the practicality of the device.
[0010] Preferably, the valve core is provided with a limiting groove, and the bottom of the valve body is provided with a stop block. The limiting groove can cooperate with the stop block to limit the rotation angle of the valve core. The limiting groove and the stop block are used to stop the valve core when it rotates after assembly, and to control the rotation angle of the valve body during operation and rest, thereby improving the practicality of the device.
[0011] Preferably, the magnetic ring also has two or more pairs of magnetic poles evenly distributed on it, while ensuring good magnetization effect; the start and stop of the motor are controlled by sensing the change of magnetic poles when the magnetic ring rotates through a Hall sensor.
[0012] Preferably, the lower housing also includes a motor shaft limiting groove at the top of the front shaft of the motor. When the motor is assembled with the lower housing, the motor shaft is placed in the motor shaft limiting groove. The motor shaft limiting groove at the top of the front shaft of the motor effectively prevents the motor from swaying left and right or moving back and forth during operation, thereby increasing the service life of the motor.
[0013] Preferably, the motor also includes a tail slot at the tail end and a limiting rib at the motor tail end mounted on the lower housing. When the motor is assembled with the lower housing, the tail slot and the limiting rib are matched, and the PCB board pins pass through the motor pin holes. Through the structural combination of the tail slot, limiting rib, pins and motor pin holes, the motor can be effectively prevented from moving during operation and its position and height on the lower housing can be fixed. After the motor is fixed in position, solder is applied to the motor pin holes to connect the motor with the PCB board pins.
