At this time, if there are foreign objects that are about to touch the pressure relief valve 1, the protective cover 11 can be used to protect the pressure relief valve 1. At this time, the small spring 13 inside the U-shaped groove 12 can shake when a collision occurs, thereby driving the protective cover 11 to shake. In this step, the protective cover 11 can be used to protect the pressure relief valve 1 during the use of the pressure relief valve 1, which can reduce the collision of foreign objects with the pressure relief valve 1, thereby reducing the damage of the pressure relief valve 1 during the use of the pressure relief valve 1, thereby increasing the service life of the pressure relief valve 1.

[0027] like Figure 1 to Figure 2As shown, a slide groove 2 is provided in the middle of the protective cover 11; a sieve plate 21 is provided inside the slide groove 2; the sieve plate 21 is slidably connected to the protective cover 11; the sieve plate 21 is located at the side of the protective cover 11; a pull plate 22 is provided on the side of the sieve plate 21; the pull plate 22 is fixedly connected to the sieve plate 21; the pull plate 22 is located at the outer side of the protective cover 11; a pull ring 23 is provided in the middle of the pull plate 22; when working, when the pipeline is depressurized to the outside through the pressure relief valve 1, the air pressure inside the protective cover 11 can be discharged through the sieve plate 21, and the dust from the outside can be reduced from entering the protective cover 11. In the event that the pressure relief valve 1 is blocked and there is a lot of dust on the surface of the sieve plate 21, the pull ring 23 can be held to pull out the pull plate 22, and then the sieve plate 21 can be pulled out from the inside of the slide 2. This step can be used to protect the pressure relief valve 1 when the protective cover 11 is used to protect the pressure relief valve 1 when it is working, thereby reducing the impact of foreign matter entering the protective cover 11 on the work of the pressure relief valve 1. When there is dust on the surface of the sieve plate 21 or it is damaged, the pulling effect of the pull ring 23 can be used to facilitate the cleaning or replacement of the sieve plate 21, thereby protecting the pressure relief valve 1 when it is working and reducing the damage to the pressure relief valve 1.

[0028] like Figure 4 As shown, a collecting strip 3 is provided in the middle of the protective cover 11; the collecting strip 3 is slidably connected with the pressure relief valve 1; a circular hole 31 is provided in the middle of the collecting strip 3; the circular hole 31 is located below the pull ring 23; a collecting groove 32 is provided in the middle of the collecting strip 3; during operation, when the sieve plate 21 is pulled out from the inside of the slide groove 2, the dust on the surface of the sieve plate 21 will fall into the inside of the protective cover 11 under the action of the protective cover 11, and at this time, the collecting groove 32 provided in the middle of the collecting strip 3 can receive the fallen dust, and then the collecting strip 3 can be pulled out from the inside of the protective cover 11 through the circular hole 31. This step can reduce the dust from falling directly into the inside of the protective cover 11 when cleaning the dust on the surface of the sieve plate 21, and further reduce the excessive dust around when the pressure relief valve 1 is working, which may cause the pressure relief valve 1 to be blocked, and further protect the pressure relief valve 1 when the pressure relief valve 1 is working.

[0029] like Figure 1 As shown, a torsion spring 4 is provided at the end of the protective sleeve 11; a plurality of torsion springs 4 are provided at the end of the protective sleeve 11; the torsion spring 4 is fixedly connected to the protective sleeve 11; a cover plate 41 is provided in the middle of the plurality of torsion springs 4; the cover plate 41 is fixedly connected to the torsion spring 4; during operation, when the pressure relief valve 1 needs to be inspected and repaired, the cover plate 41 can be opened from the end of the protective sleeve 11, and after the inspection of the pressure relief valve 1 is completed, the cover plate 41 and the end of the protective sleeve 11 can be closed by the action of the torsion spring 4. This step can be used to directly open the cover plate 41 to inspect the pressure relief valve 1 when the pressure relief valve 1 needs to be inspected and repaired, so that the pressure relief valve 1 inside the protective sleeve 11 can be easily inspected.

[0030] like Figure 1 to Figure 2 As shown, a scraper 5 is provided in the middle of the protective cover 11; the scraper 5 is fixedly connected to the protective cover 11; a plurality of scrapers 5 are provided in the middle of the protective cover 11; the scraper 5 is slidably connected to the sieve plate 21; the side of the scraper 5 is in the shape of a blade; during operation, when the dust on the surface of the sieve plate 21 is cleaned, the dust on the surface of the sieve plate 21 can be scraped by the scraper 5. In this step, when the dust on the surface of the sieve plate 21 is cleaned, the dust on the surface of the sieve plate 21 can be cleaned by the scraping action of the scraper 5, and then the dust on the surface of the sieve plate 21 can be cleaned during the process of pulling the sieve plate 21.

[0031] like Figure 1 to Figure 2 As shown, a cleaning port 6 is opened in the middle of the protective cover 11; the cleaning port 6 is located below the scraper 5; during operation, when the dust on the surface of the sieve plate 21 is scraped by the scraper 5, the dust on the outside of the sieve plate 21 can fall to the ground through the cleaning port 6. This step can make the dust on the surface of the sieve plate 21 fall to the ground directly through the cleaning port 6, thereby reducing the accumulation of dust when cleaning the sieve plate 21.

[0032] Further, such as Figure 5 As shown, a sponge pad 7 is provided on the inner wall of the protective cover 11; the sponge pad 7 is fixedly connected to the protective cover 11; during operation, when the protective cover 11 is used to protect the pressure relief valve 1, the sponge pad 7 can reduce the excessive collision between the protective cover 11 and the pressure relief valve 1. In this step, when the protective cover 11 collides with the pressure relief valve 1, the sponge pad 7 can buffer the collision point, thereby reducing the damage to the pressure relief valve 1.

[0033] Working principle: During operation, when the pressure relief valve 1 is installed on the oil tank pipeline, the protective cover 11 can be placed on the outside of the pressure relief valve 1, and then the U-shaped plate 14 can be connected to the pipeline through the nut mouth 15. At this time, if there are foreign objects that are about to touch the pressure relief valve 1, the protective cover 11 can be used to protect the pressure relief valve 1. At this time, the small spring 13 inside the U-shaped groove 12 can shake when a collision occurs, thereby driving the protective cover 11 to shake. This step can be used in the process of using the pressure relief valve 1. The protective cover 11 is used to protect the pressure relief valve 1, which can reduce the collision of foreign objects with the pressure relief valve 1, thereby reducing the damage of the pressure relief valve 1 during use, thereby increasing the service life of the pressure relief valve 1. During operation, it can be used in the pipeline. When the pressure relief valve 1 releases pressure to the outside, the air pressure inside the protective cover 11 is discharged through the sieve plate 21. The sieve plate 21 can reduce the external dust from entering the protective cover 11 and clogging the pressure relief valve 1. When there is a lot of dust on the surface of the sieve plate 21, the pull ring 23 can be held to pull out the pull plate 22, and then the sieve plate 21 can be pulled out from the chute 2. This step can reduce the external debris from entering the protective cover 11 and affecting the work of the pressure relief valve 1 when the protective cover 11 is used to protect the pressure relief valve 1 when it is working. When there is dust on the surface of the sieve plate 21 or it is damaged, the pulling effect of the pull ring 23 can be used to facilitate the cleaning or replacement of the sieve plate 21, so that the pressure relief valve 1 can be protected when the pressure relief valve 1 is working, reducing the pressure relief valve 1 from clogging. In the event of damage, during operation, when the sieve plate 21 is pulled out from the inside of the slide slot 2, the dust on the surface of the sieve plate 21 will fall into the inside of the protective cover 11 under the action of the protective cover 11. At this time, the collecting groove 32 opened in the middle of the collecting strip 3 can receive the fallen dust, and then the collecting strip 3 can be pulled out from the inside of the protective cover 11 through the circular hole 31. This step can reduce the dust from falling directly into the inside of the protective cover 11 when cleaning the dust on the surface of the sieve plate 21, and further reduce the excessive dust around the pressure relief valve 1 when it is working, which may cause the pressure relief valve 1 to be blocked, and further protect the pressure relief valve 1 when it is working. During operation, when the pressure relief valve 1 needs to be inspected and repaired, the cover plate 41 can be opened from the end of the protective cover 11, and then After the pressure relief valve 1 is inspected, the cover plate 41 and the end of the protective cover 11 can be closed by the torsion spring 4. When the pressure relief valve 1 needs to be inspected and repaired, the pressure relief valve 1 can be directly inspected by opening the cover plate 41, so that the pressure relief valve 1 inside the protective cover 11 can be inspected conveniently. During operation, when the dust on the surface of the sieve plate 21 is cleaned, the dust on the surface of the sieve plate 21 can be scraped by the scraper 5. During operation, when the dust on the surface of the sieve plate 21 is cleaned, the dust on the surface of the sieve plate 21 can be cleaned by the scraping action of the scraper 5, and then the dust on the surface of the sieve plate 21 can be cleaned in the process of pulling the sieve plate 21. During operation, when the dust on the surface of the sieve plate 21 is scraped by the scraper 5,The dust on the outside of the sieve plate 21 can fall to the ground through the dust cleaning port 6. This step can directly make the dust fall to the ground through the dust cleaning port 6 when cleaning the dust on the surface of the sieve plate 21, thereby reducing the accumulation of dust when cleaning the sieve plate 21.
