Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a chemical pipe valve. Background Art

[0002] Chemical valves are important accessories for controlling the flow of media on chemical pipelines. They are workpieces used to regulate the flow of chemical liquid transportation pipelines and adjust the opening and closing of flow paths. Since most chemical liquids are corrosive and there are gaps at the joints between pipelines and valves, although they are sealed with gaskets, after long-term use, when the gaskets age, there is still a great risk of leakage at the joints, causing chemical liquids to penetrate into the external environment, polluting the external environment and causing waste of liquid. Utility Model Content

[0003] The utility model provides a chemical pipe valve, which has the characteristics of being able to isolate the inner side of the connection between the pipe connection seat and the pipe flange from the chemical liquid on the one hand, thereby reducing the corrosion of the chemical liquid on the connection between the pipe connection seat and the pipe flange, and on the other hand, being able to increase the path for the chemical liquid to flow from the inside of the delivery pipe to the connection between the pipe connection seat and the pipe flange, thereby helping to increase the difficulty of the chemical liquid inside the pipe to penetrate to the outside through the connection of the pipe connection seat.

[0004] The utility model provides the following technical solutions: a chemical pipe valve, comprising a valve body, both ends of the valve body are fixedly connected with a pipe connecting seat, an annular isolation plate is fixedly connected to the inner wall of the pipe connecting seat, and one end of the annular isolation plate extends to the outside of the pipe connecting seat, the outer end of the annular isolation plate is fixedly connected to an annular elastic plate, the outer side of the pipe connecting seat is symmetrically provided with an outer mounting seat, and a transparent protective wall is fixedly connected between the two outer mounting seats, an outer shading ring is provided on the outer side of the transparent protective wall, and the outer shading ring is located between the two outer mounting seats.

[0005] Wherein, both ends of the outer light-shielding ring are fixedly connected with fixing buckles, and a fixing ring is wound between the two fixing buckles.

[0006] Wherein, both sides of the outer shading ring are fixedly connected with anti-skid rubber belts.

[0007] Wherein, both ends of the outer mounting seat are fixedly connected to the fixed connection seat, and the two ends of the outer mounting seat are fixed to each other through the fixed connection seat.

[0008] Wherein, an arc-shaped counterweight plate is embedded at the bottom of the annular elastic plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. With the cooperation of the annular isolation plate and the annular elastic plate, on the one hand, the inner side of the connection between the pipe connection seat and the pipe flange can be isolated from the chemical liquid, and at the same time, the inner side of the connection between the pipe connection seat and the pipe flange can be protected to reduce the corrosion of the chemical liquid to the connection between the pipe connection seat and the pipe flange. On the other hand, with the cooperation of the annular isolation plate and the annular elastic plate, the path of the chemical liquid flowing from the inside of the delivery pipeline to the connection between the pipe connection seat and the pipe flange can be increased, which helps to increase the difficulty of the chemical liquid inside the pipeline to penetrate to the outside through the connection of the pipe connection seat, thereby achieving the effect of improving the leakage-proof effect of the connection between the valve and the chemical liquid delivery pipe.

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 4The utility model provides the following technical solutions: a chemical pipe valve, comprising a valve body 1, both ends of the valve body 1 are fixedly connected with a pipe connection seat 11, an annular isolation plate 2 is fixedly connected to the inner wall of the pipe connection seat 11, and one end of the annular isolation plate 2 extends to the outside of the pipe connection seat 11, and an annular elastic plate 21 is fixedly connected to the outer end of the annular isolation plate 2, an outer side of the pipe connection seat 11 is symmetrically provided with an outer mounting seat 3, and a transparent protective wall 31 is fixedly connected between the two outer mounting seats 3, an outer side of the transparent protective wall 31 is provided with an outer shading ring 32, and the outer shading ring 32 is located between the two outer mounting seats 3.

[0019] In this embodiment: the valve body 1 is the valve body of the entire chemical pipeline, and the pipeline connection seats 11 installed at both ends of the valve body 1 are used to provide a mounting carrier for the connection between the valve body 1 and the pipeline. The annular isolation plate 2 located on the inner side of the pipeline connection seat 11 is used to isolate the inner side of the connection between the pipeline connection seat 11 and the pipeline flange from the chemical liquid, and at the same time provide inner protection for the connection between the pipeline connection seat 11 and the pipeline flange, thereby reducing the corrosion of the chemical liquid to the connection between the pipeline connection seat 11 and the pipeline flange. On the other hand, under the action of the annular isolation plate 2, the chemical liquid can be increased from the inside of the delivery pipeline to the outside of the pipeline. The path between the pipe connection seat 11 and the pipe flange connection helps to increase the difficulty of the chemical liquid inside the pipe to penetrate to the outside through the pipe connection seat 11 connection, thereby achieving the effect of improving the leakage-proof effect of the connection between the valve and the chemical liquid delivery pipe. In addition, by inserting the annular isolation plate 2 into the interior of the pipe flange during installation, the alignment and pre-installation between the pipe connection seat 11 and the flange can be completed, which helps to improve the convenience of connection between the pipe connection seat 11 and the pipe flange by the staff. At the same time, the annular isolation plate 2 is used to provide a connection carrier for the annular elastic plate 21. One end of the annular elastic plate 21 is installed during installation. Located on the inner side of the pipeline flange, at this time, it can further improve the penetration path of the liquid inside the chemical liquid delivery pipe from the inside of the pipeline to the connection between the pipeline connecting seat 11 and the flange, which helps to further improve the leakage prevention effect of the liquid during transportation. When the two symmetrically arranged outer mounting seats 3 located on the outer side of the pipeline connecting seat 11 are installed, one of the outer mounting seats 3 is installed on the outside of the pipeline connecting seat 11, and the other outer mounting seat 3 is installed on the outside of the pipeline flange. The transparent protective wall 31 located between the two outer mounting seats 3 is used to provide external protection for the connection between the pipeline connecting seat 11 and the flange, and at the same time can be at the pipeline connecting seat 11 When penetration occurs, external isolation is provided for chemical liquids that accidentally leak out, preventing the chemical liquids from directly dripping into the external environment and polluting the external environment. The transparent protective wall 31 is made of transparent material, which can facilitate the staff to visually see the location of the leakage area at the connection of the pipe connecting seat 11 through the transparent protective wall 31 when performing regular maintenance on the valve. The outer shading ring 32 located on the outside of the transparent protective wall 31 is used to protect the transparent protective wall 31 and the connection between the pipe connecting seat 11 and the pipe flange, avoiding aging of the transparent protective wall 31 and the connection between the pipe connecting seat 11 and the pipe flange due to long-term exposure.

[0020] Both ends of the outer shading ring 32 are fixedly connected with fixing buckles 321, and a fixing ring 322 is wound between the two fixing buckles 321; the fixing buckles 321 are used to provide a winding carrier for the fixing ring 322. When it is necessary to check the connection between the pipe connecting seat 11 and the pipe flange, the fixing ring 322 can be removed from the fixing buckles 321, and then the outer shading ring 32 can be removed from the outside of the transparent protective wall 31. Then, the connection between the pipe connecting seat 11 and the pipe flange can be checked. In addition, under the action of the outer shading ring 32, the connection below the transparent protective wall 31 can be tightly fitted.

[0021] Both sides of the outer light shielding ring 32 are fixedly connected with anti-skid rubber belts 323 ; wherein the anti-skid rubber belts 323 are used to increase the friction between the two sides of the outer light shielding ring 32 and the pipeline connecting seat 11 .

[0022] Both ends of the outer mounting seat 3 are fixedly connected to the fixed connection seat 33, and the two ends of the outer mounting seat 3 are fixed to each other through the fixed connection seat 33; wherein the fixed connection seat 33 is used to provide a fixed connection piece for fixing the two ends of the outer mounting seat 3.

[0023] An arc-shaped counterweight plate 211 is embedded at the bottom of the annular elastic plate 21 ; the arc-shaped counterweight plate 211 is used to increase the weight of the annular elastic plate 21 at the bottom side, thereby improving the stability of the annular elastic plate 21 in the fluid.

[0024] The working principle and use process of the utility model are as follows: when installing between the valve and the pipeline, the annular isolation plate 2 is first inserted into the inside of the pipeline flange, so as to complete the alignment and pre-installation between the pipeline connecting seat 11 and the flange. Then the staff fixes the pipeline connecting seat 11 and the flange with fixing bolts. After the fixation between the pipeline connecting seat 11 and the flange is completed, the two outer mounting seats 3 are fixed at the connection between the pipeline connecting seat 11 and the flange through the fixing connecting seat 33, and finally the outer shading ring 32 is mounted on the outer casing of the transparent protective wall 31.

[0025] When the entire valve is in use, the annular isolation plate 2 can isolate the inner side of the connection between the pipe connecting seat 11 and the pipe flange from the chemical liquid, and at the same time provide inner protection for the connection between the pipe connecting seat 11 and the pipe flange, thereby reducing the corrosion of the chemical liquid on the connection between the pipe connecting seat 11 and the pipe flange. On the other hand, under the action of the annular isolation plate 2, the path for the chemical liquid to flow from the inside of the delivery pipeline to the connection between the pipe connecting seat 11 and the pipe flange can be increased, which helps to increase the difficulty of the chemical liquid inside the pipeline to penetrate to the outside through the connection of the pipe connecting seat 11, thereby achieving the effect of improving the leakage-proof effect of the connection between the valve and the chemical liquid delivery pipe. At the same time, the external mounting seat 3 provides external protection for the connection between the pipe connecting seat 11 and the flange, and can provide external isolation for the chemical liquid that accidentally leaks when penetration occurs at the pipe connecting seat 11, thereby preventing the chemical liquid from directly dripping into the external environment and polluting the external environment.

[0026] When it is necessary to check the connection between the pipe connecting seat 11 and the pipe flange, the fixing ring 322 can be removed from the fixing buckle 321, and then the outer shading ring 32 can be removed from the outside of the transparent protective wall 31, and then the connection between the pipe connecting seat 11 and the pipe flange can be checked.
