[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1 - Figure 5 As shown, the utility model provides a chemical safety pipeline valve, including a valve body 1, one side of the valve body 1 is connected to an air inlet 2, a filter assembly 3 is arranged inside the air inlet 2, the filter assembly 3 includes a filter cartridge 301, both sides of the outer surface of the filter cartridge 301 are provided with a plug hole 302, the upper and lower ends of the filter cartridge 301 are connected to a slider 303, the upper and lower ends of the inner wall of the air inlet 2 are provided with a slide groove 304, both sides of the air inlet 2 are provided with a notch 305, the inside of the notch 305 is provided with a spring 306, the spring 306 A push block 307 is connected to one side of the push block 307, an insert block 308 is connected to one side of the push block 307, a shift block 309 is connected to the front surface of the push block 307, the outer surface of the filter cartridge 301 fits with the inner surface wall of the air inlet 2, the position and size of the slider 303 match the position and size of the slide groove 304, a sliding connection is formed between the slider 303 and the slide groove 304, an oblique opening is provided on one side of the insert block 308, the push block 307 forms an elastic structure with the spring 306 through the slot 305, and a snap-fit ​​connection is formed between the insert block 308 and the socket 302.

[0026] The effect achieved by the entire embodiment 1 is that when impurities in the chemical fluid enter the valve body 1, the impurities in the fluid will first be filtered through the filter cartridge 301, and the filtered chemical fluid enters the valve body 1. When the filter cartridge 301 in the valve body 1 needs to be cleaned after long-term use, the valve body 1 can be removed first, and then the shifting block 309 is shifted to both sides at the same time, so that the shifting block 309 drives the pushing block 307 to squeeze the spring 306, and drives the plug block 308 to be pulled out from the socket 302. When the plug block 308 is completely pulled out of the socket 302, the filter cartridge 301 can be removed from the air inlet 2, and then the filter cartridge 301 can be cleaned. That is, after cleaning the filter cartridge 301, the slider 303 of the filter cartridge 301 can be aligned with the slide groove 304, and the filter cartridge 301 can be pushed into the air inlet 2. When the filter cartridge 301 squeezes the oblique position of the plug block 308, the plug block 308 will shrink toward the groove 305. When the filter cartridge 301 is completely inserted into the air inlet 2, the spring 306 will push the push block 307 through its own elastic force to drive the plug block 308 to be inserted into the socket 302 for installation and fixation. After that, the valve body 1 can be installed and connected to the pipeline. In this way, impurities can be avoided from entering the valve body 1 to aggravate the wear of the valve body 1, thereby increasing the service life of the valve body 1.

[0027] Embodiment 2, as Figure 1 , Figure 2 and Figure 6 As shown, a protective component 4 is provided on the outer surface of the valve body 1, and the protective component 4 includes a first protective cover 401, a hinge 402 is connected to the bottom of the first protective cover 401, and a second protective cover 403 is connected to the surface of the hinge 402. Side ears 404 are connected to the surfaces of the first protective cover 401 and the second protective cover 403, and bolts 405 are inserted into the inside of the side ears 404.

[0028] The effect achieved by the entire embodiment 2 is that, after the valve body 1 is installed and used, the first protective cover 401 and the second protective cover 403 can be opened by the hinge 402, and the first protective cover 401 and the second protective cover 403 can be wrapped on the surface of the valve body 1. At this time, the bolt 405 can be passed through the side ear 404 for threaded fixation. In this way, the valve body 1 can be protected to prevent foreign objects from accidentally hitting the valve body 1 and causing chemical leakage and thus causing safety accidents, thereby improving the safety of the valve body 1.

[0029] Working principle: When impurities in the chemical fluid enter the valve body 1, the impurities in the fluid will be filtered through the filter cartridge 301 to prevent the impurities from entering the valve body 1 and aggravating the wear of the valve body 1, thereby increasing the service life of the valve body 1. After the valve body 1 is installed and used, the first protective cover 401 and the second protective cover 403 can be used to protect the valve body 1 to prevent foreign objects from accidentally hitting the valve body 1 and causing chemical leakage, thereby causing safety accidents, thereby improving the safety of the valve body 1.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
