Description

Technical Field

[0001] This utility model relates to the field of automatic air release valves, specifically an automatic air release valve for a water pump. Background Technology

[0002] Automatic air vent valves for water pumps are key devices installed at high points or specific locations in pipeline systems. They are used to automatically remove air from the pipeline, preventing airlocks and ensuring the normal operation of the pipeline system. These valves have several important functions: they automatically open when a certain amount of air accumulates in the pipeline, expelling the air; by promptly removing air, they prevent airlocks from forming in the pipeline, ensuring smooth water flow; and they also reduce pipeline vibration, noise, and corrosion caused by air accumulation, thereby extending the service life of the pipeline system. Their working principle is mainly based on a float lever type or a micro-venting mechanism. The former utilizes the buoyancy of water; when water enters the vent valve, the float rises and drives the lever to close the vent, while when air accumulates in the pipeline, the float descends, opening the vent and allowing the air to escape. The latter continuously expels small amounts of air from the pipeline through a micro-venting orifice, making it particularly suitable for applications requiring continuous air venting.

[0003] However, existing water pumps are installed in various locations, such as indoors and outdoors. But for some water pumps installed outdoors, the vent hole of the automatic air vent valve may become clogged due to dust, sand, leaves, and splashed mud and sand entering the vent hole during long-term use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automatic air vent valve for water pumps, so as to solve the technical problem that the air vent of outdoor water pump automatic air vent valves is easily blocked by dust, sand, leaves and splashed mud and sand in the air, resulting in poor air venting and affecting the normal operation of the water pump system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic air vent valve for a water pump, comprising an air vent valve, wherein the air vent valve comprises a valve body, a valve head and an air vent, and a sealing component is provided at the front end of the air vent, wherein the sealing component comprises a first sealing mechanism;

[0006] The first sealing mechanism includes two sliding seats, which are disposed at the top and bottom of the exhaust port. Each sliding seat has a groove, and a slider is slidably connected in the groove. The front end of the slider is provided with a mounting rod, and the outside of the mounting rod is provided with a return spring. The two ends of the return spring abut against the groove and the slider, respectively. The front ends of the two mounting rods are mounted with a first sealing plate through mounting ears, and the inner side of the first sealing plate is provided with a sealing block, which is adapted to the exhaust port.

[0007] By adopting the above technical solution, the exhaust valve can effectively seal the exhaust port to prevent gas or liquid leakage, while allowing the exhaust port to be opened for exhaust when needed.

[0008] Furthermore, the first sealing plate is used to seal the exhaust port, and the return spring is used to reset the first sealing plate.

[0009] By adopting the above technical solution, it is ensured that the exhaust valve can automatically close after exhaust, maintaining the system's sealing. At the same time, the design of the reset spring also enables the first sealing plate to respond quickly to pressure changes, achieving rapid opening and closing.

[0010] Furthermore, the closure assembly includes a second closure mechanism, which includes a first mounting base and a second mounting base.

[0011] By adopting the above technical solution, the sealing performance of the exhaust valve is enhanced, especially in high pressure or high temperature environments, which can more effectively prevent gas or liquid leakage.

[0012] Furthermore, the first mounting base and the second mounting base are respectively disposed at the top and bottom of the exhaust port, and the interior of the first mounting base is rotatably connected to a second sealing plate via a damping shaft.

[0013] By adopting the above technical solution, the second sealing plate can be opened or closed slowly, which helps to control the exhaust speed and avoid adverse effects on the system caused by exhaust being too fast or too slow.

[0014] Furthermore, the front end of the second mounting base is provided with a magnetic groove, and the bottom of the second sealing plate is provided with a magnetic ear.

[0015] By adopting the above technical solution, the second sealing plate can fit more tightly on the exhaust port when closed, improving the sealing performance. At the same time, the magnetic attraction also helps to maintain the stability of the second sealing plate and prevent it from shifting due to vibration or airflow impact.

[0016] Furthermore, the magnetic ear is magnetically attracted to the magnetic groove, and the damping shaft inside the first mounting base is used to reset the second sealing plate.

[0017] By adopting the above technical solution, it is ensured that the second sealing plate can automatically return to the closed state after exhaust, and the damping shaft also provides control over the movement of the second sealing plate, enabling it to open or close smoothly and slowly.

[0018] Furthermore, a valve head is provided at the top of the valve body, an exhaust port is provided on one side of the valve head, and a water pump is provided at the bottom of the valve body.

[0019] By adopting the above technical solution, the air vent valve can be easily installed on the water pump, and the position and orientation of the air vent can be adjusted according to actual needs, thus improving the versatility and flexibility of the air vent valve.

[0020] Furthermore, the water pump includes a pump body, and an exhaust pipe is provided on one side of the top of the pump body, with the top of the exhaust pipe being screwed to the valve body.

[0021] By adopting the above technical solution, the air vent valve can be directly connected to the air vent pipe of the water pump, which simplifies the installation process and ensures the sealing between the air vent valve and the water pump.

[0022] Furthermore, a switch valve is provided on the exhaust pipe.

[0023] By adopting the above technical solution, users can control the opening or closing of the exhaust pipe as needed, thereby controlling the exhaust process of the exhaust valve. The presence of the on / off valve improves the controllability and flexibility of the exhaust valve, enabling users to more accurately manage the exhaust needs of the water pump system.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model includes a sealing component, a first sealing mechanism, a sliding seat groove, a slider, a mounting rod, a return spring, a first sealing plate, and a mounting ear. The first sealing mechanism, through two sliding seats, a slider, a mounting rod, and a first sealing plate, can tightly seal the exhaust port when the exhaust valve is not working. This design effectively prevents dust, sand, leaves, and splashed mud and sand from entering the exhaust valve, thus avoiding the problem of exhaust port blockage. At the same time, the return spring can be blown open by the airflow to allow normal exhaust. After exhaust is complete, it can automatically reset and reseal the exhaust port. The first sealing mechanism is mainly suitable for water pumps with large exhaust volume.

[0026] 2. This utility model, by setting a second sealing mechanism, a first mounting base, a second mounting base, a magnetic groove, a second sealing plate, and a magnetic ear, wherein the second sealing mechanism, through the magnetic attraction between the damping shaft and the magnetic ear and the magnetic groove, allows the second sealing plate to open slowly at a small angle in scenarios with small exhaust volume, thereby precisely matching the exhaust requirements of low flow gas. Moreover, the magnetic attraction between the magnetic ear and the magnetic groove can quickly and firmly attract the second sealing plate to the exhaust port after exhaust, forming a reliable seal. In addition, the damping shaft not only controls the opening speed of the second sealing plate, but also reduces its impact and wear during opening and closing. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Example 1:

[0034] An automatic air vent valve for a water pump, such as Figures 1-4 As shown, it includes an exhaust valve 2, which includes a valve body 201, a valve head 202 and an exhaust port 203. The front end of the exhaust port 203 is provided with a sealing component 21, which includes a first sealing mechanism 22.

[0035] The first sealing mechanism 22 includes two sliding seats 204, which are located at the top and bottom of the exhaust port 203. A groove 205 is formed within each sliding seat 204, and a slider 206 is slidably connected within the groove 205. A mounting rod 207 is located at the front end of the slider 206, and a return spring 208 is located on the outer side of the mounting rod 207. Both ends of the return spring 208 abut against the groove 205 and the slider 206, respectively. A first sealing plate 209 is mounted on the front end of the two mounting rods 207 via mounting ears 210. A sealing block is located on the inner side of the first sealing plate 209, and the sealing block is adapted to the exhaust port 203. This design allows the first sealing plate 209 to respond quickly to pressure changes and automatically open or close the exhaust port 203, effectively preventing gas or liquid leakage. Simultaneously, the return spring 208 ensures that the first sealing plate 209 automatically resets after exhaust, maintaining the system's sealing performance.

[0036] See Figure 1 , Figure 2 The first sealing plate 209 is used to seal the exhaust port 203, and the return spring 208 is used to reset the first sealing plate 209. This design not only improves the sealing performance of the exhaust valve, but also enhances its automatic control and reset capability. During the exhaust process, the first sealing plate 209 can fit tightly against the exhaust port 203, effectively preventing gas or liquid leakage. After the exhaust is completed, the return spring 208 can quickly pull the first sealing plate 209 back to its original position, preparing for the next exhaust.

[0037] The implementation principle of this embodiment is as follows: First, when the water pump system is in normal operation and no venting is required, the first sealing plate 209 of the first sealing mechanism 22 is tightly attached to the vent 203 under the action of the return spring 208, forming a reliable seal, which effectively prevents the intrusion of external impurities and air. At this time, the slider 206 is located at a certain position of the slide groove 205, maintaining the stable sealing state of the first sealing plate 209.

[0038] Example 2:

[0039] When gas is generated inside the water pump system and needs to be vented, the gas pressure acts on the first sealing plate 209, overcoming the elastic force of the return spring 208, and pushing the slider 206 to slide in the slide groove 205, so that the first sealing plate 209 gradually moves away from the vent port 203, thereby opening the venting channel, and the gas is discharged to the outside of the system through the vent port 203, thus realizing the venting function.

[0040] After the venting is completed, as the internal gas pressure of the system decreases, the elastic force of the return spring 208 causes the slider 206 to drive the first sealing plate 209 back to its original position, re-sealing the vent port 203 and restoring the system to its sealed state. The first sealing mechanism 22 realizes the automatic opening and closing of the vent port 203 through the linkage between the return spring 208 and the slider 206, ensuring the normal operation of the water pump system and the venting requirements.

[0041] See Figure 1 , Figure 3 , Figure 4 The sealing component 21 includes a second sealing mechanism 23, which includes a first mounting base 211 and a second mounting base 212. The second sealing mechanism 23 provides an additional sealing layer for the exhaust valve through the magnetic attraction of the first mounting base 211, the second mounting base 212, the damping shaft, the magnetic ear 215, and the magnetic groove 213. This design allows the second sealing piece 214 to fit more tightly onto the exhaust port 203, significantly improving the sealing performance of the exhaust valve, and is particularly suitable for exhaust needs in high-pressure or harsh environments.

[0042] See Figure 1 , Figure 3 , Figure 4 The first mounting base 211 and the second mounting base 212 are respectively disposed at the top and bottom of the exhaust port 203. The second sealing plate 214 is rotatably connected inside the first mounting base 211 through a damping shaft. This design allows the second sealing plate 214 to open or close slowly and smoothly. The damping shaft not only controls the movement speed of the second sealing plate 214, but also reduces the impact and noise when it opens and closes, thereby improving the working stability and service life of the exhaust valve.

[0043] See Figure 1 , Figure 3 , Figure 4 The front end of the second mounting base 212 is provided with a magnetic groove 213, and the bottom of the second sealing plate 214 is provided with a magnetic ear 215. This magnetic design allows the second sealing plate 214 to fit more tightly on the exhaust port 203 when closed, improving the sealing performance. At the same time, the magnetic force also enhances the stability of the second sealing plate 214, preventing it from shifting or opening due to vibration or airflow impact, further ensuring the sealing performance of the system.

[0044] See Figure 1 , Figure 3 , Figure 4 The magnetic ear 215 is magnetically attracted to the magnetic groove 213, and the damping shaft inside the first mounting base 211 is used to reset the second sealing plate 214. This design ensures that the second sealing plate 214 can automatically and accurately return to the closed state after exhaust, maintaining the system's sealing performance. At the same time, the presence of the damping shaft also improves the smoothness and controllability of the movement of the second sealing plate 214.

[0045] See Figure 1 , Figure 3 , Figure 4 The valve body 201 has a valve head 202 on the top and an exhaust port 203 on one side. The valve body 201 has a water pump 1 at the bottom. This structure allows the exhaust valve to be easily installed on the water pump, and the position and orientation of the exhaust port 203 can be adjusted according to actual needs. This design improves the versatility and flexibility of the exhaust valve, enabling it to adapt to water pump systems of different models and specifications.

[0046] See Figure 1 , Figure 3 , Figure 4 The water pump 1 includes a pump body 101. An exhaust pipe 102 is provided on one side of the top of the pump body 101, and the top of the exhaust pipe 102 is screwed to the valve body 201. This connection method not only simplifies the installation process of the exhaust valve, but also ensures the sealing between the exhaust valve and the water pump. At the same time, the screw connection method also facilitates the disassembly and maintenance of the exhaust valve, improving the maintainability of the system.

[0047] See Figure 1 , Figure 3 , Figure 4 The exhaust pipe 102 is equipped with a switch valve 103. This design allows users to control the opening or closing of the exhaust pipe 102 as needed, thereby flexibly managing the exhaust process of the water pump system. The presence of the switch valve 103 improves the controllability and flexibility of the exhaust valve, enabling users to more accurately control the exhaust volume and exhaust time to meet the exhaust requirements under different working conditions.

[0048] The implementation principle of this embodiment is as follows: First, when the water pump system is in normal operation and the exhaust volume is small or more precise control of the exhaust process is required, the second sealing plate 214 is kept closed under the action of the damping shaft and is tightly attached to the exhaust port 203 to ensure the sealing of the system.

[0049] When a small amount of gas is generated inside the system or when slow exhaust is required, the gas pressure or subtle changes inside the system will act on the second sealing plate 214. Due to the design of the damping shaft, the second sealing plate 214 will not open completely immediately, but will rotate slowly at a small angle to gradually open the exhaust channel. This slow opening method helps to accurately control the exhaust volume and avoid excessive exhaust or system pressure fluctuations.

[0050] During the exhaust process, the magnetic attraction between the magnetic ear 215 and the magnetic groove 213 provides a certain holding force for the second sealing plate 214, ensuring that it maintains a stable position during the exhaust process and will not swing randomly due to external vibration or airflow impact. At the same time, this magnetic attraction design also makes it easy for the second sealing plate 214 to quickly and accurately return to the closed state after the exhaust is completed.

[0051] After the exhaust is completed, as the internal gas pressure decreases, the second sealing plate 214 gradually returns to its original position under the action of the damping shaft. At the same time, the magnetic attraction between the magnetic lug 215 and the magnetic groove 213 accelerates its return process, ultimately causing the second sealing plate 214 to fit tightly against the exhaust port 203, restoring the system to a sealed state.
