Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water pumps, specifically a heating water valve. Background Technology
[0002] The heater core valve in an automotive air conditioning system is a key component, relying on the engine's cooling water circulation to provide the heat source and control the heating system. Currently, various types are available on the market, including disc valves, plunger valves, diverter valves, and shut-off valves, but they generally suffer from performance defects. Disc valves are difficult to position and prone to internal leakage; plunger valves, made of POM (polyoxymethylene) plastic plungers and PDM (ethylene propylene diene monomer) rubber stoppers, struggle to meet the requirements for long service life and controllable flow; diverter valves will short-circuit if deviated from the fully open position, causing coolant to flow directly back to the engine, making flow regulation almost impossible; shut-off valves, as the opening decreases, the upstream water pressure increases, leading to an unexpected flow rate and failing to achieve linear control between the opening angle and flow rate. In addition, existing heating water valves suffer from several common problems: poor sealing performance, allowing external moisture to easily seep in and cause corrosion; unsuitable materials for valve core seals, affecting opening and closing speed and sealing durability; control structures in some products, such as threaded rods and threaded sleeves, are prone to wear due to particle ingress, reducing performance; some products add various composite materials to improve weather resistance, increasing manufacturing costs but still failing to prevent environmental factors from corroding and oxidizing the shell. These problems limit the overall performance and service life of heating water valves.
[0003] Application number CN202323645015.7 discloses a warm air water valve, including a valve body, a valve cavity inside the valve body, a valve core inside the valve cavity, a drive shaft on the top of the valve body, one end of the drive shaft connected to the valve core and the other end equipped with an electromagnet, a steering shaft connected in series on the drive shaft, an adjusting seat outside the steering shaft, an adjusting plate rotatably connected to the adjusting seat, an adjusting hole on the adjusting plate, and an electric push rod between the adjusting seat and the adjusting plate; a first water inlet hole on the left side of the valve body, a second water inlet hole on the right side, a third water inlet hole on the front end, and a fourth water inlet hole on the rear end; a water outlet hole on the bottom of the valve body; a side hole on the valve core, one end matching the first or third water inlet hole and the other end matching the second or fourth water inlet hole, and a central hole on the valve core matching the water outlet hole, the central hole communicating with the side hole. This heating water valve features multi-channel diversion and convenient diversion, with complete overall functions and strong practicality; however, it has a shortcoming: when the device is in use, it is not yet able to filter the heat flow inside the device, so the presence of dirt in the flow will affect subsequent use.

[0027] By installing the cleaning component 4 on the device, the device can achieve a filtering effect when guiding the flow of heat. After a period of use, the internal dirt is discharged by squeezing, avoiding the flow obstruction caused by dirt blockage.
[0028] The water valve pipe assembly 1 includes a connecting pipe 101, a connecting pipe 2 103 installed on the other side of the connecting pipe 101, a central regulating pipe 102 connected between the connecting pipe 2 103 and the connecting pipe 101, a cleaning pipe 104 connected to the outer wall of one side of the central regulating pipe 102, and a mounting support plate 105 fixedly installed on the top of the central regulating pipe 102. The water valve pipe assembly 1 serves as the basic frame, and the connecting pipe 101, the connecting pipe 2 103 and the central regulating pipe 102 constitute the main channel for hot water flow, while the cleaning pipe 104 provides a channel for the cleaning function.
[0029] Several limit lock slots 1051 are provided around the mounting plate 105.
[0030] The regulating assembly 2 includes a brake lever 201, which is limited and installed on the top inner side of the central regulating pipe 102. A flow regulating plug 203 is fixedly installed at the bottom of the brake lever 201, and a brake shaft 202 is fixedly installed at the top of the brake lever 201. The flow regulating plug 203 in the regulating assembly 2 can change the connection state of the three-way pipe 2031 by rotating the brake lever 201, thereby regulating the flow path and flow rate of hot water. The filter filling sponge mesh 2032 can filter the flowing hot water.
[0031] The flow regulating plug 203 is cylindrical, and a three-way pipe 2031 is opened in the middle of the flow regulating plug 203. Two of the three-way pipes 2031 are respectively connected to the internal pipes of the connecting pipe 2 103 and the connecting pipe 1 101, and the other cylinder of the three-way pipe 2031 corresponds to the inside of the cleaning pipe 104. The three-way pipe 2031 is in a "T" shape, and a filter filling sponge mesh 2032 is fixedly installed inside the three-way pipe 2031.
[0032] The locking adjustment assembly 3 includes a fixed handle 301, which is fixedly installed on the top outer wall of the brake lever 201. A tough spring 302 is fixedly installed on the inner middle side of the fixed handle 301. A pressing handle 305 is fixedly installed at the end of the tough spring 302. The middle of the pressing handle 305 is limited by a limiting rod 303 and installed on the front end of the fixed handle 301. A limiting latch 304 is fixedly installed at the front end of the pressing handle 305. The limiting latch 304 is correspondingly limited inside the limiting locking groove 1051. The locking adjustment assembly 3 can fix the position of the adjustment assembly 2 through the cooperation of the limiting latch 304 and the limiting locking groove 1051, ensuring the stability of the adjusted state.
[0033] This heating water valve achieves the functions of regulating and cleaning hot water flow through the coordinated operation of its various components. The water valve pipe assembly 1 serves as the basic framework, with connecting pipe 101, connecting pipe 2 103, and the central regulating pipe 102 forming the main channel for hot water flow, while the cleaning pipe 104 provides a channel for cleaning. In the regulating assembly 2, the flow regulating plug 203 can change the connection state of the tee pipe 2031 by rotating the brake lever 201, thereby regulating the flow path and flow rate of the hot water. The filter-filled sponge mesh 2032 filters the flowing hot water. The locking regulating assembly 3, through the cooperation of the limit lock 304 and the limit lock groove 1051, can fix the position of the regulating assembly 2, ensuring the stability of the adjusted state. The cleaning assembly 4, using the telescopic cleaning rod 401 and the return spring 402, can clean the inside of the pipes. During the operation, when the hot water valve is not in operation, the flow regulating plug 203 of the regulating component 2 is in the initial position, the three-way pipe 2031 is not connected to the connecting pipe 101, the connecting pipe 203 and the cleaning pipe 104, and the limiting latch 304 of the locking regulating component 3 is limited in the corresponding limiting lock groove 1051, fixing the initial state of the entire device. When it is necessary to adjust the hot water flow, press the pressing handle 305 of the locking regulating component 3. Under the limiting action of the limiting rod 303, the pressing handle 305 compresses the tough spring 302, causing the limiting latch 304 to disengage from the limiting lock groove 1051. Then, by rotating the brake lever 201 through the fixed handle 301, the brake lever 201 drives the flow regulating plug 203 at the bottom to rotate, so that the two ends of the three-way pipe 2031 are connected to the internal pipes of connecting pipe one 101 and connecting pipe two 103 respectively. Hot water enters from connecting pipe one 101, is filtered by the three-way pipe 2031 and the filter filling sponge mesh 2032, and then flows out from connecting pipe two 103. After adjustment, release the pressing handle 305. Under the action of the tough spring 302, the limit lock 304 is repositioned in the corresponding limit lock groove 1051, fixing the adjusted state. When the pipe needs to be cleaned, follow the above adjustment steps and rotate the brake lever 201 to connect the other end of the three-way pipe 2031 to the cleaning pipe 104. Then press the squeeze button 404 of the cleaning component 4. The squeeze button 404 compresses the reset spring 402, causing the telescopic cleaning rod 401 to extend and retract inside the cleaning pipe 104 to clean the inside of the pipe. After cleaning, release the squeeze button 404. Under the action of the return spring 402, the telescopic cleaning rod 401 and the squeeze button 404 return to their initial positions. When hot water flow is no longer needed, press the press handle 305 again and rotate the brake lever 201 to return the flow regulating plug 203 to its initial position. The tee pipe 2031 is disconnected from all pipes. Release the press handle 305, and the limit lock 304 stops the device.
