Description

Technical Field

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

[0002] Plastic valves are widely used in many fields such as industrial production, water supply and drainage systems, chemical industry, and food and beverage industry due to their advantages such as corrosion resistance, light weight, low cost, and convenient installation. However, as various industries continue to increase their requirements for fluid control precision and sealing performance, the shortcomings of traditional plastic valves in terms of leakage prevention performance have gradually become apparent.

[0003] Existing plastic valves only use a single sealing ring for sealing when connected to external pipelines, resulting in a limited sealing method and a lack of alerts when the sealing effect is poor, making it difficult for staff to handle the situation in a timely manner. Therefore, we propose a leak-proof plastic valve. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a leak-proof plastic valve that has the advantages of being leak-proof. It solves the problem that existing plastic valves, when connected to external pipelines, only use a single sealing ring for sealing, resulting in a single sealing method and no warning function when the sealing effect is poor, making it impossible for staff to handle the situation in a timely manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof plastic valve, comprising a valve body, wherein a fixing ring is fixedly connected to both sides of the inner wall of the valve body, a first sealing ring is fixedly connected to one side of the fixing ring, a second sealing ring is fixedly connected to both sides of the valve body, a connecting ring is fixedly connected to both sides of the outer surface of the valve body, a sealing gasket is fixedly connected to one side of the connecting ring, a circular ring is contacted to one side of the first sealing ring, a pressure ring is fixedly connected to one side of the circular ring, and a connecting pipe is fixedly connected to one side of the pressure ring.

[0006] Preferably, a hollow block is fixedly connected to the front of the valve body, a lead screw is movably connected to one side of the hollow block, an adjusting plate is threaded onto the surface of the lead screw, an elastic telescopic rod is fixedly connected to one side of the adjusting plate, a sealing plate is fixedly connected to one side of the elastic telescopic rod, a contact switch is provided on one side of the sealing plate, and an air guide pipe is connected to the other side of the hollow block, with one end of the air guide pipe extending through to one side of the connecting ring.

[0007] Preferably, a fixing seat is fixedly connected to the outer surface of the connecting pipe, and bolts are inserted into the inner cavities of both the fixing seat and the connecting ring, with a nut threaded onto one side of the bolt surface.

[0008] Preferably, one side of the lead screw is movably connected to the hollow block via a bearing, and the other side of the lead screw is fixedly connected to a rotating handle.

[0009] Preferably, a rectangular plate is fixedly connected to one side of the contact switch, and the bottom of the rectangular plate is fixedly connected to the hollow block.

[0010] Preferably, the inner cavity of the adjusting plate is slidably connected to a slide rod, and one side of the slide rod is fixedly connected to a hollow block. A storage battery and a buzzer are fixedly connected to the bottom of the hollow block from left to right.

[0011] Compared with the prior art, this utility model provides a leak-proof plastic valve, which has the following advantages:

[0012] 1. When installing this utility model, the connecting pipe is inserted into the valve body, so that the ring contacts the first sealing ring. Moreover, when the connecting pipe contacts the sealing gasket, the pressure ring also contacts the second sealing ring, thus achieving triple sealing, resulting in a good sealing effect and making it less prone to material leakage during operation.

[0013] 2. After the present invention is connected, rotating the handle causes the lead screw to rotate, which in turn moves the adjusting plate. The adjusting plate then moves the elastic telescopic rod, which in turn moves the sealing plate, thus generating negative pressure. When the sealing plate cannot move, the elastic telescopic rod will stretch. When the sealing effect is poor, gas will enter the inner cavity of the air guide tube and then the inner cavity of the hollow block. At this time, the tension of the elastic telescopic rod will cause the sealing plate to move, making the sealing plate contact the contact switch. At this time, the buzzer will sound to alert the staff. Attached Figure Description

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3As shown, a hollow block 11 is fixedly connected to the front of the valve body 1. A lead screw 12 is movably connected to one side of the hollow block 11. An adjusting plate 13 is threadedly connected to the surface of the lead screw 12. An elastic telescopic rod 14 is fixedly connected to one side of the adjusting plate 13. A sealing plate 15 is fixedly connected to one side of the elastic telescopic rod 14. A contact switch 17 is provided on one side of the sealing plate 15. An air guide pipe 20 is connected to the other side of the hollow block 11.

A rotating handle is fixedly connected to the other side of the lead screw 12. A rectangular plate 16 is fixedly connected to one side of the contact switch 17. The bottom of the rectangular plate 16 is fixedly connected to the hollow block 11. A sliding rod is slidably connected to the inner cavity of the adjusting plate 13, and one side of the sliding rod is fixedly connected to the hollow block 11. A battery 18 and a buzzer 19 are fixedly connected to the bottom of the hollow block 11 from left to right.

[0025] The specific function of this technical solution is as follows: After connection, rotating the handle drives the lead screw 12 to rotate, the lead screw 12 drives the adjusting plate 13 to move, the adjusting plate 13 drives the elastic telescopic rod 14 to move, and the elastic telescopic rod 14 drives the sealing plate 15 to move, thereby generating negative pressure. When the sealing plate 15 cannot move, the elastic telescopic rod 14 will stretch. When the sealing effect is poor, gas will enter the inner cavity of the air guide pipe 20, and then the gas will enter the inner cavity of the hollow block 11. At this time, the tension of the elastic telescopic rod 14 drives the sealing plate 15 to move, so that the sealing plate 15 contacts the contact switch 17. At this time, the buzzer 19 will work to remind the staff.

[0026] Working principle: During installation, the connecting pipe 9 is inserted into the valve body 1, so that the ring 7 contacts the first sealing ring 3. When the connecting pipe 9 contacts the sealing gasket 6, the pressure ring 8 also contacts the second sealing ring 4, thus achieving triple sealing, which results in a good sealing effect and makes it less likely to leak material during operation.

[0027] After connection, rotate the handle, which drives the lead screw 12 to rotate. The lead screw 12 drives the adjusting plate 13 to move, which in turn drives the elastic telescopic rod 14 to move. The elastic telescopic rod 14 then drives the sealing plate 15 to move, thereby generating negative pressure. When the sealing plate 15 cannot move, the elastic telescopic rod 14 will stretch. When the sealing effect is poor, gas will enter the inner cavity of the air guide tube 20 and then the inner cavity of the hollow block 11. At this time, the tension of the elastic telescopic rod 14 drives the sealing plate 15 to move, so that the sealing plate 15 contacts the contact switch 17. At this time, the buzzer 19 will work to remind the staff.
