Description

Technical Field

[0001] This utility model mainly relates to the field of exhaust valves, specifically to an anti-jamming exhaust valve with self-cleaning function. Background Technology

[0002] Anti-jamming air release valves are special valves designed to automatically release gas and prevent valve core jamming in fluid pipeline systems. They are widely used in heating, water supply, air conditioning, and industrial pipeline systems. Their core function is to release air while, through structural optimization, preventing impurities or scale buildup from obstructing valve core movement, thus ensuring long-term stable operation.

[0003] In the invention patent application CN201810846954.2, published on March 12, 2024, entitled "An Exhaust Valve", the invention includes a main valve body, a main valve cover, a valve cover, a valve disc assembly, a float assembly, and a first micro exhaust valve. The main valve cover is disposed on the main valve body and supports the valve cover. An air intake hole is provided on the main valve cover. The separation or contact between the valve disc assembly and the main valve cover controls the opening or closing of the air intake hole. The device can automatically realize the opening and closing of the exhaust hole by setting the locking mechanism, which has a high degree of automation and reduces manual operation.

[0004] However, after prolonged use, a large amount of deposits will accumulate on the surface of the filter screen inside the exhaust valve, causing blockage inside the exhaust valve. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides an anti-jamming exhaust valve with a self-cleaning function to solve the problem that after a long period of operation, a large amount of deposits will accumulate on the surface of the internal filter screen of the exhaust valve, causing blockage inside the exhaust valve.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a self-cleaning anti-jamming exhaust valve, comprising a pressure relief cylinder, a vent hole provided on the front end face of the pressure relief cylinder, an exhaust body provided on one side surface of the pressure relief cylinder, a sealing handle provided at the top of the pressure relief cylinder, and a back passage pipe provided on the back of the pressure relief cylinder.

[0009] The exhaust body includes a valve body shell, one end of which is provided with a threaded pipe, and the other end of which is provided with an exhaust screen. The outer surface of the valve body shell is provided with an embedded groove, and an outer sleeve is slidably connected to the surface of the embedded groove. A tension spring is fixedly connected to the surface of the exhaust screen, and a circular top cover is fixedly connected to the top surface of the tension spring. A sliding rod is sleeved inside the tension spring, and a rotating scraper is provided inside the outer sleeve.

[0010] Furthermore, the exhaust body is installed on the surface of the pressure relief cylinder via a threaded pipe, and a hollow cavity is provided inside the exhaust body.

[0011] Furthermore, the bottom end of the tension spring is fixedly connected to the outer surface of the exhaust screen, and the other end is fixedly connected to the bottom surface of the disc top cover. The disc top cover forms an elastic telescopic structure on the surface of the sliding rod through the tension spring.

[0012] Furthermore, two rotating scrapers are provided inside the outer sleeve, and the rotating scrapers form a rotational friction structure on the surface of the exhaust screen by the rotation of the outer sleeve.

[0013] Furthermore, the rotating scraper rotates along the edge of the tension spring, and the surface of the exhaust screen is provided with several ventilation holes.

[0014] Furthermore, the threaded pipe and the hollow chamber and outer sleeve inside the exhaust body are interconnected, and both ends of the outer sleeve are open.

[0015] 3. Beneficial effects:

[0016] This utility model is reasonably designed. When the pressure relief cylinder is venting, the high-pressure air enters the hollow chamber inside the valve body through the threaded pipe and is transported to the inside of the outer sleeve through the exhaust screen. The high-pressure air pushes the disc top cover, causing it to be discharged from the gap between the disc top cover and the outer sleeve. When the pressure drops, the disc top cover is pulled back to its original position along the sliding rod under the action of the tension spring, thus sealing the valve. When the exhaust screen surface accumulates after long-term operation, the outer sleeve is manually rotated, causing the rotating scraper inside the outer sleeve to rub against the exhaust screen surface and scrape off the accumulated material, thus achieving the purpose of cleaning the inside of the exhaust valve after long-term operation.

[0027] See attached document Figure 1-4 The device includes a pressure relief cylinder 1, a vent hole 2 on the front end face of the pressure relief cylinder 1, an exhaust body 3 on one side surface of the pressure relief cylinder 1, a sealing handle 4 on the top of the pressure relief cylinder 1, and a back passage pipe 5 on the back side of the pressure relief cylinder 1. The exhaust body 3 is installed on the surface of the pressure relief cylinder 1 through a threaded pipe 302. The exhaust body 3 has a hollow cavity inside. This device achieves the function of venting and cleaning the valve at the same time through the exhaust body 3.

[0028] The exhaust body 3 includes a valve body shell 301. A threaded pipe 302 is provided at one end of the valve body shell 301, and an exhaust screen 303 is provided on the surface of the other end of the valve body shell 301. An inner groove 304 is provided on the outer surface of the valve body shell 301, and an outer sleeve 305 is slidably connected to the surface of the inner groove 304. A tension spring 306 is fixedly connected to the surface of the exhaust screen 303, and a circular top cover 307 is fixedly connected to the top surface of the tension spring 306. A sliding rod 308 is sleeved inside the tension spring 306. A rotating scraper 309 is provided inside the outer sleeve 305, and the bottom end of the tension spring 306 is fixedly connected to the outside of the exhaust screen 303. The side surface is fixedly connected to the bottom surface of the circular top cover 307. The circular top cover 307 forms an elastic telescopic structure on the surface of the sliding rod 308 through the tension spring 306. Two rotating scrapers 309 are provided inside the outer sleeve 305. The rotating scrapers 309 form a rotational friction structure on the surface of the exhaust screen 303 through the rotation of the outer sleeve 305. The rotating scrapers 309 rotate along the edge of the tension spring 306. The surface of the exhaust screen 303 is provided with several vent holes. The threaded pipe 302 and the hollow cavity and outer sleeve 305 inside the exhaust body 3 are interconnected. Both ends of the outer sleeve 305 are open.

[0029] In this embodiment, when the pressure relief cylinder 1 is venting, the high-pressure air enters the hollow chamber inside the valve body shell 301 through the threaded pipe 302, and is transported to the inside of the outer sleeve 305 through the exhaust screen 303. The high-pressure air pushes the disc top cover 307, causing the high-pressure air to be discharged from the gap between the disc top cover 307 and the outer sleeve 305. When the pressure drops, the disc top cover 307 is pulled back to its original position along the sliding rod 308 under the action of the tension spring 306, performing a sealing operation. When the surface of the exhaust screen 303 accumulates after long-term operation, the outer sleeve 305 is manually rotated, causing the rotating scraper 309 inside the outer sleeve 305 to rub against the surface of the exhaust screen 303, scraping off the accumulation on the surface of the exhaust screen 303, thus achieving the purpose of cleaning the inside of the exhaust valve after long-term operation.
