Description

Technical Field

[0001] This utility model relates to the field of exhaust valve technology, and in particular to a self-cleaning exhaust valve. Background Technology

[0002] An air release valve is a device installed in fluid transport systems (such as pipelines and containers) to automatically release accumulated gas within the system, ensuring normal fluid flow. Its core function is to release excess gas by opening / closing the valve port to balance pressure and prevent problems such as gas lock and cavitation. Commonly used in HVAC, water supply and drainage, and industrial pipelines, they can be classified into float type, lever type, and diaphragm type according to their structure. Some also have self-cleaning functions to maintain long-term efficient operation.

[0003] Most existing exhaust valves are float-type. However, after long-term use, the float wears down and may cause incomplete closure, which may lead to media leakage or air backflow. They require frequent maintenance and repair. In addition, after long-term use, impurities in the medium can easily adhere to the valve body wall, air inlet and other parts that are prone to dirt accumulation, thus contaminating the internal environment of the exhaust valve and causing internal parts to jam, affecting the use of the equipment.

[0004] Therefore, we propose a self-cleaning exhaust valve to solve the above problems. Utility Model Content

[0010] Specifically, a conical cap is fixedly installed on the top of the bracket, and the outer side of the conical cap abuts against the sealing sleeve to facilitate the sealing of the exhaust valve.

[0011] Specifically, a sealing ring is fixedly installed on the top of the closed sleeve, and a silicone scraper ring is fixedly installed on the outside of the closed sleeve, with the silicone scraper ring in contact with the inner wall of the exhaust valve body.

[0012] Specifically, a conical head is fixedly installed at the bottom of the central shaft, and multiple turbine blades are fixedly installed on the outer side of the rotating turbine. The water flow impacting the multiple turbine blades can drive the rotating turbine to rotate.

[0013] Specifically, a rotating wheel and a rotating sleeve are rotatably sleeved on the outer side of the central shaft. The rotating turbine, the rotating wheel, and the rotating sleeve are fixedly connected in sequence.

[0021] Reference Figure 1-5 A self-cleaning exhaust valve includes an exhaust valve body 1, a closed base 7 fixedly installed on the inner side of the exhaust valve body 1, and a closed sleeve 10 slidably installed on the outer side of the closed base 7; an exhaust port is opened on the top of the closed base 7, a bracket 8 is fixedly installed on the inner side of the exhaust port, a central shaft 13 is fixedly installed on the bottom of the bracket 8, and a rotating turbine 15 is rotatably sleeved on the central shaft 13.

[0022] In this embodiment, a flange 2 is fixedly installed at the bottom of the exhaust valve body 1 to facilitate connection with the pipeline.

[0023] In this embodiment, an exhaust head 4 is fixedly inserted through the top of the exhaust valve body 1, and a dust cover 3 is fixedly installed on the top of the exhaust valve body 1 to prevent external dust from falling into the exhaust valve.

[0024] In this embodiment, an exhaust plate 5 is fixedly installed on the inner side of the exhaust head 4. The top of the exhaust plate 5 is provided with multiple exhaust holes 6. The multiple exhaust holes 6 are all narrow at the top and wide at the bottom, which facilitates the discharge of gas while preventing liquid from overflowing.

[0025] In this embodiment, a conical cap 9 is fixedly installed on the top of the bracket 8. The outer side of the conical cap 9 abuts against the sealing sleeve 10, which facilitates the sealing of the exhaust valve.

[0026] In this embodiment, a sealing ring 11 is fixedly installed on the top of the closed sleeve 10, and a silicone scraper ring 12 is fixedly installed on the outside of the closed sleeve 10. The silicone scraper ring 12 is in contact with the inner wall of the exhaust valve body 1.

[0027] In this embodiment, a conical head 14 is fixedly installed at the bottom of the central shaft 13, and multiple turbine blades 16 are fixedly installed on the outer side of the rotating turbine 15. The water flow impacting the multiple turbine blades 16 can drive the rotating turbine 15 to rotate.

[0028] In this embodiment, a rotating wheel 17 and a rotating sleeve 19 are rotatably sleeved on the outer side of the central shaft 13. The rotating turbine 15, the rotating wheel 17 and the rotating sleeve 19 are fixedly connected in sequence. Multiple silicone scrapers 18 are fixedly installed on the outer side of the rotating wheel 17. All of the silicone scrapers 18 are in contact with the inner wall of the exhaust valve body 1. Multiple silicone scrapers 20 are fixedly installed on the outer side of the rotating sleeve 19. All of the silicone scrapers 20 are in contact with the inner wall of the exhaust port. The exhaust port can be cleaned by the silicone scrapers 20.

[0029] Working Principle: When using the exhaust valve, fluid enters the valve body and flows from bottom to top. It first impacts the turbine blades 16, causing the rotating turbine 15 to rotate, which in turn drives the rotating wheel 17 and rotating sleeve 19 to rotate synchronously. As the rotating wheel 17 rotates and the buoyancy causes the closed sleeve 10 to rise, multiple silicone scrapers 18 and silicone scraper rings 12 clean the inner wall of the exhaust valve body 1. The rotating sleeve 19 rotates, causing multiple silicone scrapers 20 to rotate, cleaning the inside of the exhaust port and reducing the adhesion of impurities. The scraped-off impurities are discharged from the exhaust valve body 1 with the circulating fluid, preventing obstruction of the closed sleeve 10. When air is present in the exhaust valve body 1, it gradually accumulates in the upper space of the valve body. As the amount of air increases, the fluid level in the valve body drops, and the closed sleeve 10 gradually descends due to reduced buoyancy. When the sealing sleeve 10 descends, the conical cover 9 is exposed, opening the vent at the top of the sealing base 7. Air is quickly discharged from the vent. During the venting process, the flow of fluid within the valve body creates some disturbance, which helps to flush down impurities adhering to the inner wall of the valve body and near the vent, and these impurities are discharged from the valve body with the fluid circulation. The air is discharged through the vent head 4 and the vent plate 5. The vent plate 5 has multiple vent holes 6, which are narrow at the top and wide at the bottom, facilitating gas discharge while preventing liquid overflow. After the air is exhausted, the fluid in the valve body 1 gradually fills the valve body, and the sealing sleeve 10 rises with the liquid level. The rising sealing sleeve 10 fits tightly against the conical cover 9, blocking the vent, closing the venting channel, and preventing fluid leakage.

[0030] The technological advancements of this invention compared to existing technologies are as follows: the rotating turbine 15 utilizes water flow to drive the silicone scraper 18 and silicone scraper 20 to rotate, cleaning the inner wall of the exhaust valve and preventing impurities in the medium from adhering to the valve body, air inlet, and other parts. Furthermore, the enclosing sleeve 10 can be moved by water flow, thereby achieving the opening and closing of the exhaust valve. This effectively solves the problem of easy wear of the float ball after prolonged use and extends the service life of the equipment.
