Description

Technical Field

[0001] The utility model relates to the technical field of chemical instrument valves, in particular to a chemical instrument valve that is easy to connect. Background Art

[0002] Chemical instrument valve is a kind of pipeline accessory, whose main function is to change the passage section and the flow direction of the medium, and control the flow of the conveying medium. These valves are usually composed of valve body, valve cover, valve core, valve seat and sealing device, and can adjust the flow and pressure of the medium as needed to meet the requirements of the process.

[0003] For example, a chemical instrument valve that is easy to connect is disclosed in Chinese patent CN221075640U. By setting a filter box, when the medium in the pipeline leaks due to aging or damage at the pipeline connection, the filter box can ensure that the medium will not leak out directly through the damaged connection, but first enter the filter box through the filter net on the groove, so that the filter adsorption material in the filter box filters and adsorbs the harmful medium and then discharges it to the outside through the discharge port, which can minimize the harm to the environment after the leakage.

[0004] For this structure, although the pipeline joints can be treated to prevent leakage, the chemical instrument valve and the pipeline are connected by bolts. Over time, the bolts will rust, making it inconvenient to disassemble them. Therefore, we propose a chemical instrument valve that can quickly connect the chemical instrument valve and the pipeline, which is convenient for disassembly during maintenance, so as to improve the maintenance efficiency of the chemical instrument valve and the pipeline. Utility Model Content

[0005] The utility model aims to provide a chemical instrument valve which is easy to connect, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical instrument valve that is easy to connect, comprising a chemical instrument valve body, a connecting pipe fixedly installed on the outer wall of the chemical instrument valve body, a pipeline is arranged on the side of the connecting pipe away from the chemical instrument valve body, and a processing component is arranged outside the connecting pipe, the processing component includes a disassembly and assembly component arranged on the outer wall of the connecting pipe, and an anti-detachment component is clamped inside the disassembly and assembly component.

[0007] Preferably, the disassembly and assembly component includes a limit ring fixedly installed on the outer wall of the connecting pipe, a sealing ring is fixedly installed on the end of the connecting pipe away from the chemical instrument valve body, a first connecting ring is rotatably connected to the outer wall of the connecting pipe, a limit groove is provided on the inner wall of the first connecting ring, a clamping frame is fixedly installed on the outer wall of the first connecting ring, a clamping block is fixedly installed on the outer wall of the clamping frame, a second connecting ring is fixedly installed on the outer wall of the pipeline, and a sealing groove is provided on the outer wall of the second connecting ring.

[0008] Preferably, the anti-slip assembly includes a card hole opened on the outer wall of the card frame, a card pin is clamped inside the card hole, a slide groove is opened inside the card pin, a retaining ring is slidably arranged inside the slide groove, a sliding rod is fixedly installed on the side wall of the retaining ring, a spring is sleeved on the outer wall of the sliding rod, and a pressing block is fixedly installed on the end of the sliding rod away from the retaining ring.

[0009] Preferably, the sealing ring is made of rubber material, and the sealing ring is clamped with the sealing groove, under which the sealing performance of the connecting pipe and the pipeline can be enhanced.

[0010] Preferably, the outer wall of the card block is arranged in an inclined surface, and there are four card blocks, which are divided into two groups and distributed around the circumference of the first connecting ring. When the card frame is in contact and squeezed with another card block, the inclined surface of the card block can make the card block slide more smoothly into the inside of the card frame. When the card frame and the card block are connected, the sealing ring is in close contact with the sealing groove, which can enhance the sealing effect.

[0011] Preferably, the slide rod and the slide groove are slidably arranged, and the outer wall of the pressing block is arranged in an arc surface. Under its restriction, when the pressing block slides into the slide groove, the arc surface of the pressing block can make the locking pin slide smoothly inside the locking hole.

[0012] Preferably, one end of the spring is fixedly mounted on the side of the pressing block away from its arc surface, and the other end of the spring away from the pressing block is fixedly mounted on the inner wall of the slide groove. Under the limitation of the spring elasticity, when the pressing block is not squeezed, the pin can be prevented from sliding out of the locking hole, and under the limitation of the retaining ring, the slide rod can be prevented from sliding out of the slide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The chemical instrument valve which is easy to connect is composed of a disassembly and assembly component as one part. When the pipeline and the chemical instrument valve body are installed, the connecting pipe fixedly installed on the outer wall of the chemical instrument valve body is aligned with the pipeline. When the first connecting ring is aligned and contacted with the second connecting ring, the sealing ring fixedly installed on the outer wall of the connecting pipe is clamped with the sealing groove provided on the outer wall of the second connecting ring. Under the restriction of the second connecting ring and the sealing groove, the sealing performance of the connecting pipe and the pipeline can be improved. At this time, the first connecting ring is rotated. Since the limiting groove provided on the inner wall of the first connecting ring rotates with the limiting ring, under the restriction of the limiting ring, the first connecting ring can be avoided. The connecting ring falls off from the outer wall of the connecting pipe, and the rotating first connecting ring drives the clamping frame and the clamping block fixedly installed on its outer wall to rotate accordingly. The clamping frame fixedly installed on the outer wall of the first connecting ring is clamped with the clamping block fixedly installed on the outer wall of the second connecting ring, and the clamping block fixedly installed on the outer wall of the first connecting ring is clamped with the clamping frame fixedly installed on the outer wall of the second connecting ring. Since the end of the clamping block away from the clamping frame is arranged in an inclined surface, under its restriction, as the first connecting ring rotates, the second connecting ring fixedly installed on the outer wall of the pipeline is tightly connected with the first connecting ring rotatably connected to the outer wall of the connecting pipe, and the sealing ring is tightly squeezed with the sealing groove to improve the sealing effect.

[0015] 2. The chemical instrument valve which is easy to connect is composed of an anti-detachment component as one of its components. When the first connecting ring is connected to the second connecting ring, the card frame is engaged with the card block. In order to prevent the chemical instrument valve body from being separated from the pipeline when in use, the card pin is engaged with the card hole opened on the outer wall of the card frame and the card block, so as to prevent the first connecting ring from rotating and causing the connecting pipe to be separated from the pipeline. When the card pin is engaged with the card hole, it is necessary to be more stable. Under the restriction of the pressing block, the card pin can be prevented from slipping out of the card hole. When it is necessary to disassemble the pipeline, the pressing block is pressed to make the sliding rod fixedly installed on the top surface of the pressing block slide into the inside of the slide groove. The pressing block compresses the spring and slides the pressing block into the inside of the slide groove. At this time, the card pin is pulled, so that the card pin can be removed from the inside of the card hole. When the pressing block is not squeezed, the pressing block is pushed out of the slide groove under the action of the spring elasticity, so as to prevent the card pin from slipping out of the inside of the card hole.

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] A preferred embodiment of a chemical instrument valve that is easy to connect provided by the utility model is as follows: Figures 1 to 6 As shown: a chemical instrument valve that is easy to connect, including a chemical instrument valve body 1;

[0026] A connecting pipe 2 is fixedly installed on the outer wall of the chemical instrument valve body 1;

[0027] A pipeline 3 is provided on the side of the connecting pipe 2 away from the chemical instrument valve body 1;

[0028] And a processing component 4 is arranged on the outside of the connecting pipe 2, the processing component 4 includes a disassembly and assembly component 41 arranged on the outer wall of the connecting pipe 2, the disassembly and assembly component 41 includes a limit ring 411 fixedly installed on the outer wall of the connecting pipe 2, a sealing ring 412 is fixedly installed on the end of the connecting pipe 2 away from the chemical instrument valve body 1, a first connecting ring 413 is rotatably connected to the outer wall of the connecting pipe 2, a limit groove 414 is provided on the inner wall of the first connecting ring 413, a clamping frame 415 is fixedly installed on the outer wall of the first connecting ring 413, a clamping block 416 is fixedly installed on the outer wall of the clamping frame 415, a second connecting ring 417 is fixedly installed on the outer wall of the pipeline 3, and a sealing groove 418 is provided on the outer wall of the second connecting ring 417.

[0029] In this embodiment, when the pipeline 3 and the chemical instrument valve body 1 are installed, the connecting pipe 2 fixedly installed on the outer wall of the chemical instrument valve body 1 is aligned with the pipeline 3. When the first connecting ring 413 and the second connecting ring 417 are aligned and contacted, the sealing ring 412 fixedly installed on the outer wall of the connecting pipe 2 is clamped with the sealing groove 418 opened on the outer wall of the second connecting ring 417. Under the restriction of the second connecting ring 417 and the sealing groove 418, the sealing performance of the connecting pipe 2 and the pipeline 3 can be improved. At this time, the first connecting ring 413 is rotated. Since the limiting groove 414 opened on the inner wall of the first connecting ring 413 rotates with the limiting ring 411, under the restriction of the limiting ring 411, the first connecting ring 413 can be prevented from falling off from the outer wall of the connecting pipe 2. The first connecting ring 413 drives the clamping frame 415 and the clamping block 416 fixedly installed on its outer wall to rotate accordingly, and the clamping frame 415 fixedly installed on the outer wall of the first connecting ring 413 is clamped with the clamping block 416 fixedly installed on the outer wall of the second connecting ring 417, and the clamping block 416 fixedly installed on the outer wall of the first connecting ring 413 is clamped with the clamping frame 415 fixedly installed on the outer wall of the second connecting ring 417. Since the end of the clamping block 416 away from the clamping frame 415 is arranged in an inclined surface, under its restriction, as the first connecting ring 413 rotates, the second connecting ring 417 fixedly installed on the outer wall of the pipeline 3 is tightly connected with the first connecting ring 413 rotatably connected to the outer wall of the connecting pipe 2, and the sealing ring 412 is tightly squeezed with the sealing groove 418 to improve the sealing effect.

[0030] Furthermore, the sealing ring 412 is made of rubber material, and the sealing ring 412 is engaged with the sealing groove 418 , under which the sealing performance of the connecting pipe 2 and the pipeline 3 can be enhanced.

[0031] Furthermore, the outer wall of the card block 416 is set in an inclined surface. There are four card blocks 416, which are divided into two groups and distributed around the center of the first connecting ring 413. When the card frame 415 is in contact and squeezed with another card block 416, the inclined surface of the card block 416 can make the card block 416 slide more smoothly into the inside of the card frame 415. When the card frame 415 and the card block 416 are engaged, the sealing ring 412 is in close contact with the sealing groove 418, which can enhance the sealing effect.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of a chemical instrument valve that is easy to connect provided by the utility model is as follows: Figures 1 to 6 As shown: the anti-slip component 42 includes a card hole 421 opened on the outer wall of the card frame 415, a card pin 422 is clamped inside the card hole 421, a slide groove 423 is opened inside the card pin 422, a retaining ring 424 is slidably arranged inside the slide groove 423, a slide rod 425 is fixedly installed on the side wall of the retaining ring 424, a spring 426 is sleeved on the outer wall of the slide rod 425, and a pressing block 427 is fixedly installed on the end of the slide rod 425 away from the retaining ring 424.

[0034] In this embodiment, after the first connecting ring 413 is connected to the second connecting ring 417, the clamping frame 415 is clamped with the clamping block 416. In order to prevent the chemical instrument valve body 1 from being separated from the connecting pipe 2 and the pipeline 3 when the chemical instrument valve body 1 is in use, the clamping pin 422 is clamped with the clamping hole 421 opened on the outer wall of the clamping frame 415 and the clamping block 416, so as to prevent the first connecting ring 413 from rotating and causing the connecting pipe 2 to be separated from the pipeline 3. When the clamping pin 422 is clamped with the clamping hole 421, it is required to be more stable. Under the restriction of the pressing block 427, the clamping pin 422 can be prevented from slipping out of the clamping hole 421. 1. When the pipe 3 needs to be disassembled, the pressing block 427 is pressed to make the sliding rod 425 fixedly installed on the top surface of the pressing block 427 slide into the sliding groove 423. The pressing block 427 compresses the spring 426 and slides the pressing block 427 into the sliding groove 423. At this time, the latch 422 is pulled to remove the latch 422 from the inside of the latch hole 421. When the pressing block 427 is not squeezed, the pressing block 427 is pushed out of the sliding groove 423 under the elastic action of the spring 426 to prevent the latch 422 from sliding out of the inside of the latch hole 421.

[0035] Furthermore, the slide rod 425 is slidably arranged with the slide groove 423 , and the outer wall of the pressing block 427 is arranged in an arc surface. Under its restriction, when the pressing block 427 slides into the inside of the slide groove 423 , the arc surface of the pressing block 427 can make the locking pin 422 slide smoothly inside the locking hole 421 .

[0036] In addition, one end of the spring 426 is fixedly installed on the side of the pressing block 427 away from its arc surface, and the other end of the spring 426 away from the pressing block 427 is fixedly installed on the inner wall of the slide groove 423. Under the elastic limitation of the spring 426, when the pressing block 427 is not squeezed, the pin 422 can be prevented from sliding out of the locking hole 421. Under the limitation of the retaining ring 424, the slide rod 425 can be prevented from sliding out of the slide groove 423.

[0037] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
