Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a corrosion-resistant CPVC valve body. Background Art

[0002] CPVC valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of fluids. They have the advantages of light weight, strong corrosion resistance, compact and beautiful external structure, easy installation due to light body weight, strong corrosion resistance, wide application range, hygienic and non-toxic material, wear resistance, easy disassembly, and simple maintenance. They are suitable for water, air, oil, and corrosive chemical liquids. However, in the existing CPVC valves during use, the valve pipes are directly in contact with corrosive liquids, lacking other anti-corrosion measures, which will reduce their anti-corrosion effect and service life. At the same time, when corrosion problems occur, the entire valve needs to be disassembled and replaced, increasing the replacement cost. Therefore, a corrosion-resistant CPVC valve body is proposed.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments without creative efforts belong to the scope of protection.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-3 , a corrosion-resistant CPVC valve body, including a valve pipeline 1, connection flanges 2 are installed on both sides of the valve pipeline 1, four installation grooves 3 are opened on the inner wall of the valve pipeline 1, installation plates 4 are slidably installed on the inner walls of the four installation grooves 3, an anti-corrosion sleeve 5 is installed inside the four installation plates, limit insertion blocks 6 are fixedly installed at the outer ends of the installation plates 4 on both sides of the valve pipeline 1, fixed frames 7 are fixedly installed outside both sides of the valve pipeline 1, limit grooves 8 are opened on the outer sides of the fixed frames 7, installation frames 9 are fixedly installed on the outer sides of the fixed frames 7, limit rods 10 are slidably installed inside the installation frames 9, springs 11 are sleeved on the outer sides of the limit rods 10, pressure plates 12 are fixedly installed on the outer sides of the limit rods 10, and limit holes 13 are opened on the outer side surfaces of the limit insertion blocks 6.

[0023] Preferably, one end of the spring 11 close to the valve pipeline 1 is connected to the surface of the pressure plate 12, the other end of the spring 11 far from the valve pipeline 1 is connected to the inner wall of the installation frame 9, grooves corresponding to the limit insertion blocks 6 are opened on the surface of the connection flange 2, and sealing rings 14 are arranged at the outer ends of the anti-corrosion sleeves 5.

[0024] Preferably, the anti-corrosion sleeve 5 is composed of an organosilicon anti-corrosion layer, a rigid calcium silicate tile insulation layer, a galvanized iron wire reinforcement layer, and an organosilicon coating of titanium aluminum alloy powder.

[0025] Working principle: The anti-corrosion sleeve 5 is installed inside the valve pipeline 1, isolating the inner wall of the entire valve pipeline 1. The anti-corrosion sleeve 5 is composed of an organosilicon anti-corrosion layer, a rigid calcium silicate tile insulation layer, a galvanized iron wire reinforcement layer, and an organosilicon coating of titanium aluminum alloy powder, and has a good anti-corrosion effect. It can directly protect the inner wall of the valve pipeline 1 from corrosion. When it is necessary to replace or clean the inside, manually pull the limiting rods 10 on both sides. The limiting rods 10 will move to both sides and drive the pressing plate 12 to move. When the pressing plate 12 moves, it will compress the spring 11. As the limiting rods 10 move, the limiting rods 10 will leave the limiting holes 13, and then the limiting inserts 6 will lose their restraint, and the anti-corrosion sleeve 5 will lose its restraint. At this time, the anti-corrosion sleeve 5 can be manually taken out, and the inside of the valve pipeline 1 can be cleaned and the anti-corrosion sleeve 5 can be replaced. When installing, align the mounting plate 4 on the outside of the anti-corrosion sleeve 5 with the mounting groove 3 and install it. Then, similarly pull the limiting rods 10, and install the limiting inserts 6 into the limiting grooves 8. After that, release the limiting rods 10. Under the elastic force of the spring 11, the limiting rods 10 will be installed into the limiting holes 13. Then, connect it to the external pipeline through the connecting flange 2. At the same time, the setting of the sealing ring 14 ensures the sealing performance, and then the installation of the anti-corrosion sleeve 5 is completed, thereby improving the anti-corrosion property of the valve pipeline 1, increasing the service life, and facilitating the replacement or cleaning of the anti-corrosion parts and maintenance, solving the problem that when the existing valve is corroded, the entire valve needs to be replaced, which will increase the replacement cost.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-3 , a upper pipe 15 is fixedly installed in the middle upper part of the valve pipeline 1. A sealing plate 16 is installed at the upper end of the upper pipe 15. Threaded holes are provided on the outer surface of the outer circle of the sealing plate 16 and on the outer circle of the upper pipe 15, and bolts 19 are threadedly installed in the threaded holes.

[0028] Preferably, a threaded rod 17 is threadedly installed on the surface of the sealing plate 16. A chute is provided on the inner wall of the upper pipe 15, and a baffle 18 is slidably installed on the inner wall of the chute. The lower end of the threaded rod 17 is movably connected to the upper part of the baffle 18.

[0029] Preferably, an anti-corrosion layer is coated on the surface of the baffle 18.

[0030] Working principle: By rotating the threaded rod 17, the baffle 18 can be moved up and down, and the opening and closing and flow rate of the valve can be controlled. The anti-corrosion layer can improve the anti-corrosion effect of the baffle 18. At the same time, by removing the bolts 19, the sealing plate 16 can be removed, and then the baffle 18 can be taken out and replaced.

[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit, and the scope is defined by the appended claims and their equivalents.
