Description

Technical Field

[0001] This utility model relates to the field of plastic valve technology, specifically to a plastic valve protection device. Background Technology

[0002] Plastic valves are valve devices made of plastic materials used to control the flow of fluids (such as liquids or gases) in piping systems. Compared to traditional metal valves, plastic valves typically offer advantages such as lighter weight, better corrosion resistance, and suitability for specific chemical environments. They are widely used in industries such as manufacturing, chemical engineering, water treatment, biotechnology, and pharmaceuticals to control fluid direction, flow rate, and pressure, as well as to prevent leaks and ensure the safety and reliability of system operation.

[0003] However, traditional plastic valves lack external protective devices, making them susceptible to contamination or physical damage from the external environment, thus making it difficult to ensure normal operation. To address these issues, the inventors have proposed a plastic valve protection device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a plastic valve protection device, including a plastic valve body 1. Both ends of the plastic valve body 1 are fixedly connected to connecting pipes 2 via flanges. The outer side of the plastic valve body 1 is covered with symmetrically distributed transparent shell 3 and transparent shell 4. The bottom ends of transparent shell 3 and transparent shell 4 are hinged together. The top ends of transparent shell 3 and transparent shell 4 are fixedly connected with symmetrically distributed fixing blocks 5. A bolt 22 is provided on one side of each fixing block 5. One end of each bolt 22 movably passes through the two corresponding fixing blocks 5 and is threaded with a nut 21. A rotating component is provided at the top end of transparent shell 4, and a detection component is provided at the top end of transparent shell 3.

[0020] The rotating assembly includes two fixed plates 6, which are fixedly connected to the top of the transparent housing 4. A worm gear 7 is rotatably connected between the two fixed plates 6. A valve stem 8 is rotatably connected to the top of the plastic valve body 1. A worm wheel 9 is fixedly connected to the outside of the valve stem 8. The worm wheel 9 and the worm gear 7 are meshed together.

[0021] By adopting the above technical solution, the worm 7 is rotated, and the worm 7 and worm wheel 9 are meshed together, which simultaneously drives the valve stem 8 to rotate, thereby controlling the opening and closing of the valve. Furthermore, the reverse self-locking property between the worm 7 and worm wheel 9 is used to prevent the valve from rotating spontaneously, ensuring the stability of the valve during opening and closing.

[0022] The detection assembly includes a fixed cylinder 11, which is fixedly connected to the top of the transparent housing 3. An air inlet pipe 12 is connected to the bottom of the fixed cylinder 11, and the air inlet pipe 12 communicates with the interior of the transparent housing 3. A piston plate 13 is slidably engaged inside the fixed cylinder 11. A top contact rod 14 is fixedly connected to the middle of the top of the piston plate 13. A tactile switch 15 is fixedly installed on the top of the inner wall of the fixed cylinder 11.

[0023] By adopting the above technical solution, when a leak occurs at the connection between the plastic valve body 1 and the connecting pipe 2, the leaked gas enters the interior of the fixed cylinder 11 through the air inlet pipe 12 and pushes the piston plate 13 to move upward along the inner wall of the fixed cylinder 11. At the same time, it drives the top contact rod 14 to move upward, so that the top contact rod 14 contacts the tactile switch 15, thereby triggering an alarm signal.

[0024] Both sides of the transparent housing 1 3 and the transparent housing 2 4 are provided with mounting grooves 17. A sealing ring 18 is placed inside the mounting groove 17. The sealing ring 18 is sleeved on the outside of the corresponding connecting pipe 2. The top of the transparent housing 1 3 and the connecting pipe 2 are provided with mounting grooves 2 19. A sealing ring 20 is placed inside the mounting groove 2 19. The sealing ring 20 is sleeved on the top connection of the plastic valve body 1.

[0025] By adopting the above technical solution and setting sealing ring 18 and sealing ring 20, the sealing performance of the contact parts between transparent housing 3 and transparent housing 4 and valve body is improved.

[0026] A buzzer 16 is fixedly installed at the top of the fixed cylinder 11, and the buzzer 16 is electrically connected to the tactile switch 15.

[0027] By adopting the above technical solution and setting a buzzer 16, it is easy to issue an alarm signal.

[0028] One end of the rotating shaft of the worm gear 7 extends to one side of the fixed plate 6 and is fixedly connected to the handle 10.

[0029] By adopting the above technical solution and setting the throttle 10, it is easier to rotate and adjust the worm gear 7.

[0030] A bolt 22 is provided on one side of the top of the fixed cylinder 11.

[0031] By adopting the above technical solution and setting bolts 22, it is easy to balance the pressure inside the fixed cylinder 11.

[0032] Working principle: When protecting the plastic valve, transparent housing 1 3 and transparent housing 2 4 are placed on the outside of the plastic valve body 1, and the relative position between transparent housing 1 3 and transparent housing 2 4 is fixed by the cooperation between bolt 22 and nut 21, so that transparent housing 1 3 and transparent housing 2 4 can protect the plastic valve body 1.

[0033] When the valve is opened and closed, the worm 7 is rotated, and the worm 7 and worm wheel 9 are meshed and connected, which drives the valve stem 8 to rotate, thereby controlling the opening and closing of the valve. The reverse self-locking property between the worm 7 and worm wheel 9 is used to prevent the valve from rotating spontaneously and to ensure the stability of the valve when opening and closing.

[0034] Furthermore, when a leak occurs at the connection between the plastic valve body 1 and the connecting pipe 2, the leaked gas enters the interior of the fixed cylinder 11 through the air inlet pipe 12 and pushes the piston plate 13 to move upward along the inner wall of the fixed cylinder 11. At the same time, it drives the top contact rod 14 to move upward, so that the top contact rod 14 contacts the tactile switch 15, thereby triggering the buzzer 16 to sound an alarm.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
