Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a protective structure for valves. Background Technology

[0002] During transportation and storage after manufacturing, valves typically have their medium inlet and outlet open. This allows foreign matter such as dust, sand, moisture, and even insects to easily enter the valve body and adhere to critical components like the flow channel walls, valve seat, and valve core. Once the valve is in use, these residual foreign objects can cause problems such as valve core jamming, scratches on the sealing surface, and incomplete closure, severely affecting the valve's normal operating performance and service life.

[0003] Currently, although there are protective methods such as using plastic blind flanges or tape to temporarily seal the interfaces, plastic blind flanges are prone to loosening and falling off during transportation, resulting in insufficient protection reliability, while tape is prone to leaving adhesive residue when removed, causing secondary pollution.

[0024] Example

[0025] refer to Figures 1-2 A protective structure for a valve includes a valve body 1, both ends of which are provided with flanges 2 for connecting to external pipelines, and a first protective half cover 3 and a second protective half cover 4 are detachably provided on the flanges 2.

[0026] refer to Figure 3 The inner wall of the flange 2 is fixedly connected to two symmetrically arranged extension plates 201, and the upper and lower parts of the extension plates 201 are fixedly connected to positioning rods 202.

[0027] refer to Figures 4-5 The second protective half-cover 4 has mounting plates 401 fixedly connected to both sides. The bottom of each mounting plate 401 has an integrally formed fastening plate 402. A locking groove 403 is formed through the fastening plate 402. The first protective half-cover 3 has fixing blocks 301 symmetrically fixedly connected to both sides. The top surface of each fixing block 301 has an opening groove 302 for the fastening plate 402 to be inserted into. A hollow groove 303 communicating with the opening groove 302 is formed inside the fixing block 301, allowing for sliding within the hollow groove 303. A displacement plate 304 is movably connected. A plurality of springs 305 are provided on one side of the displacement plate 304. One end of the spring 305 is fixedly connected to the displacement plate 304, and the other end of the spring 305 is fixedly connected to the inner side wall of the slot 303. A locking block 306 that can be engaged into the locking slot 403 is fixedly connected to the other side of the displacement plate 304 on both sides of the locking block 306. A sliding rod 307 extending to the outside of the fixed block 301 is fixedly connected to the displacement plate 304 on both sides of the locking block 306. A drive plate 308 is provided between the two sliding rods 307.

[0028] The first protective half-cover 3 and the second protective half-cover 4 are each provided with an insertion slot 404 for the end of the extension plate 201 to be inserted. The first protective half-cover 3 and the second protective half-cover 4 are each provided with a connecting plate 405. The connecting plate 405 is provided with a positioning slot 406 for the positioning rod 202 to be inserted. By inserting the extension plate 201 on the flange 2 into the insertion slot 404 of the first protective half-cover 3 and the second protective half-cover 4, and by inserting the positioning rod 202 on the extension plate 201 into the positioning slot 406 of the connecting plate 405, the first protective half-cover 3 and the second protective half-cover 4 are initially positioned and installed on the flange 2, preventing them from moving or falling off easily.

[0029] The first protective half-cover 3 and the second protective half-cover 4 are each provided with a mounting groove 407 that is compatible with the flange 2. The mounting groove 407 allows the first protective half-cover 3 and the second protective half-cover 4 to form a complete protective cover, which encloses the flange 2 and increases the overall stability and sealing.

[0030] The second protective half-cover 4 is provided with a sealing plate 408, and the first protective half-cover 3 is provided with a sealing groove 309 that allows the sealing plate 408 to be inserted. Through the setting of the sealing plate 408 and the sealing groove 309, a secondary sealing function is realized, ensuring that the joint between the first protective half-cover 3 and the second protective half-cover 4 has good sealing performance when they are closed, thus improving the overall dustproof and waterproof level.

[0031] The working principle of this utility model:

[0032] During installation, firstly, align the mounting slots 407 of the first protective half-cover 3 and the second protective half-cover 4 with the flange 2, and then align them from both sides of the flange 2 towards the center. Insert the extension plate 201 on the flange 2 into the insertion slots 404 of the first protective half-cover 3 and the second protective half-cover 4, and insert the positioning rod 202 on the extension plate 201 into the positioning slot 406 of the connecting plate 405. This achieves the initial positioning and installation of the first protective half-cover 3 and the second protective half-cover 4 on the flange 2. Simultaneously, the sealing plate 408 on the second protective half-cover 4 is inserted into the sealing groove 309 on the first protective half-cover 3, achieving a secondary sealing function. During this process, the fastening plates 402 on both sides of the second protective half-cover 4 will naturally insert into the opening slots 302 on the fixing block 301 of the first protective half-cover 3. At this point, simply press the drive plate 308 on the fixed block 301 inward. The drive plate 308 will then drive the displacement plate 304 and the locking block 306 to move inward synchronously through the slide rod 307, and compress the spring 305. When the fastening plate 402 is inserted into place, the locking groove 403 on it will move just in front of the locking block 306. After releasing the drive plate 308, the spring 305 will restore its deformation and drive the displacement plate 304 and the locking block 306 to reset. The locking block 306 will then be inserted into the locking groove 403 of the fastening plate 402. At this time, the first protective half cover 3 and the second protective half cover 4 are firmly locked together to form a complete protective cover, which encloses the flange 2 and ensures the reliability of the overall structure. It is not easy to loosen even during transportation bumps.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
