Description

Technical Field

[0001] The utility model relates to the technical field of self-sealing valves, in particular to a self-sealing valve structure for preventing external leakage. Background Technique

[0002] The working principle of a self-sealing valve mainly utilizes the wedge sealing surface to enhance the sealing effect under pressure, so that the greater the pressure, the better the sealing performance. The design of this valve utilizes the medium pressure or other external pressures to enhance the sealing performance. Specifically, when the valve is under pressure, the specific pressure on the sealing surface increases with the increase of the medium pressure, thereby improving the sealing performance.

[0003] When installing the valve, attention should be paid to the overall sealing performance of the valve to avoid external leakage of the valve, which may affect the sealing performance and other properties of the valve.

[0004] After the valve is installed for a period of time, attention should be paid to the states of the two pipe orifices on the valve to avoid external leakage from the pipe orifices, which may lead to poor sealing performance of the valve. For this reason, we propose a self-sealing valve structure for preventing external leakage to solve the above technical problems. Content of the Utility Model

[0011] Preferably, a plurality of reinforcing plates are fixedly arranged inside the leak-proof cavity, and a plurality of water-permeable holes are arranged on one side of the reinforcing plates.

[0012] By adopting the above technical solution, the reinforcing plate plays a supporting role in the anti-leakage cavity of the anti-leakage ring, making the anti-leakage cavity more stable.

[0013] Preferably, a reinforcing ring is fixed on one side of the anti-leakage ring facing the self-sealing valve body, and the reinforcing ring is fixedly connected to the inner sides of the left and right ports of the self-sealing valve body.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Reference Figures 1-5 , an anti-leakage self-sealing valve structure, comprising a self-sealing valve body 1, and further comprising:

[0032] The leakproof ring 2, the number of which is two, is fixedly connected to the inner sides of the left and right ports of the self-sealing valve body 1, and the inner side of the leakproof ring 2 has a leakproof cavity, and a plurality of reinforcing plates 5 are fixed to the inner side of the leakproof cavity, and a plurality of water-permeable holes are provided on one side of the reinforcing plate 5. The reinforcing plate 5 plays a supporting role in the leakproof cavity on the leakproof ring 2, making the leakproof cavity more stable;

[0033] Two support rings 8 are provided on the inner side of the leak-proof ring 2, and a plurality of support blocks 9 are fixed on the outer side of the support ring 8. The support blocks 9 are fixedly connected to the inner side of the leak-proof ring 2. The support rings 8 and the support blocks 9 support the leak-proof ring 2, making the leak-proof ring 2 more stable and reducing the probability of deformation of the leak-proof ring 2.

[0034] A reinforcement ring 6 is fixed on the side of the anti-leakage ring 2 facing the self-sealing valve body 1. The reinforcement ring 6 is fixedly connected to the inner sides of the left and right ports of the self-sealing valve body 1. The reinforcement ring 6 improves the connection strength between the anti-leakage ring 2 and the self-sealing valve body 1, making the anti-leakage ring 2 more stable in the self-sealing valve body 1.

[0035] Flange rings 3, there are two flange rings 3, and the flange rings 3 are fixedly connected to the outer sides of the left and right ports of the self-sealing valve body 1;

[0036] Installation grooves are provided at both the left and right ends of the self-sealing valve body 1 and at one end of the leakage prevention ring 2 away from the self-sealing valve body 1 on the outside. A sealing ring 10 is installed inside the installation groove, and the sealing ring 10 plays a role in sealing the interface between the self-sealing valve body 1 and the leakage prevention ring 2, improving the overall sealing performance of the device.

[0037] Connecting pipes 4, and the number of connecting pipes 4 is two. A through holes are provided at both the left and right ports of the self-sealing valve body 1, and a B through hole is provided on the outside of the leakage prevention ring 2. The B through hole communicates with the leakage prevention cavity, and the A through hole communicates with the B through hole. The connecting pipes 4 are fixedly connected to the inside of the A through hole and the B through hole. A one-way valve 7 is installed on the upper side of the connecting pipe 4 through threaded sealing, and the one-way valve 7 can prevent liquid backflow.

[0038] Principle of use:

[0039] When installing the valve, insert the leakage prevention ring 2 into the pipeline, and then connect the valve and the pipeline together through the flange ring 3, so that the leakage prevention ring 2 blocks the contact surface between the valve and the pipeline. When problems such as excessive liquid pressure occur, the leakage prevention ring 2 will be broken through first, and the liquid will enter the leakage prevention ring 2, and then flow out through the connecting pipe 4 and the one-way valve 7, avoiding the rapid collapse of the leakage prevention ring 2. The one-way valve 7 prevents liquid from flowing back to ensure the internal pressure of the pipe body. At the same time, the liquid flows from the one-way valve 7 to the detector and the collection shell, allowing personnel to know that there is a problem with the pipeline in the first time.
