Description

Technical Field

[0001] This utility model relates to the field of pipeline valve technology in well chambers, specifically a wall-mounted airbag valve. Background Technology

[0002] In China, the airbag valve is also known as a pinch valve, pipe clamp valve, or clamp shut-off valve. The sleeve is the most important component of any pinch valve and is the core of the pinch valve. It provides corrosion resistance, wear resistance, and pressure resistance. The quality of the pinch valve depends on the quality of the sleeve. The sleeve is squeezed by pneumatic, electric, manual, or hydraulic drive to achieve the functions of opening and closing and regulation.

[0003] The gates commonly used for cutting off the inlet and outlet of pipelines inside existing manholes have problems such as large space requirements (a certain amount of space is required vertically or horizontally, and they cannot be used in narrow environments) and defects in transmission methods (electric screw transmission has a high failure rate, cannot be submerged in water, has a long transmission distance, and hydraulic transmission is expensive).

[0004] Therefore, a solution is needed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides an abdominal wall-type airbag valve. It has the following beneficial effects:

[0015] This solution utilizes a wall-mounted airbag valve to inflate and deflate the air chamber between the steel outer shell and the rubber inner liner via an air vent pipe. This causes the rubber inner liner to expand, cutting off the flow channel and contracting, allowing the medium to pass through. It eliminates the need for the vertical movement space required by traditional gate valves, making it perfectly suited for low-ceilinged well chamber environments. The pneumatic control system replaces electric screws or hydraulic transmissions, significantly reducing the failure rate, allowing for submersion in water, and at a much lower cost than hydraulic transmission systems. Furthermore, the steel outer shell, fixed flange, and mounting flange are seamlessly integrated, with a sealing ring between the flange seat and the fixed base further enhancing sealing. The installation device achieves a secure connection through large locking blocks, small locking blocks, and wedge-shaped hooks. Combined with the lifting block on top of the steel outer shell, this facilitates construction, hoisting, and positioning. The simple pneumatic control structure also reduces maintenance difficulty and cost. From spatial adaptability, transmission reliability, sealing stability to construction and maintenance convenience, this solution comprehensively optimizes the shortcomings of existing well chamber gate valves.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example 1

[0024] Regarding the aforementioned problems, the commonly used gates for cutting off the inlet and outlet of pipelines inside manholes have the following drawbacks: large space requirements (a certain amount of space is needed vertically or horizontally, making them unusable in confined spaces) and defects in transmission methods (high failure rate of electric screw drives, inability to be submerged in water, long transmission distance, and high cost of hydraulic drives).

[0025] The solution is as follows: An abdominal wall-type airbag valve includes a device body 1, which includes an airbag valve device 2, a mounting device 3, and a lifting rod device 4. The mounting device 3 is fixed to the right end of the airbag valve device 2 by bolts. The lifting rod device 4 is located above the airbag valve device 2. The airbag valve device 2 includes a steel outer shell 5, a fixed flange 6, a mounting flange 7, a rubber inner liner 9, and an air vent tube 11. The steel outer shell 5, the fixed flange 6, and the mounting flange 7 are all smoothly transitioned and integrally formed structures. The fixed flange 6 is located at the left end of the steel outer shell 5, and the mounting flange 7 is located at the right end of the steel outer shell 5. The steel outer shell 5 has a cylindrical structure and a hollow interior. Both the fixed flange 6 and the mounting flange 7 have flow channels 8 inside. The rubber inner liner 9 is installed inside the steel outer shell 5. An air chamber 10 is provided between the rubber inner liner 9 and the steel outer shell 5. The air vent tube 11 is installed on the top of the steel outer shell 5, and the bottom of the air vent tube 11 is connected to the rubber inner liner 9.

[0026] Analysis of the above content: The main body of the device 1 includes an airbag valve device 2, an installation device 3, and a lifting rod device 4. The installation device 3 is fixed to the right end of the airbag valve device 2 by bolts, and the lifting rod device 4 is used for hoisting assistance. In the airbag valve device 2, the steel outer shell 5, fixed flange 6, and mounting flange 7 are integrally machined with a smooth transition, ensuring structural strength and sealing performance. The steel outer shell 5 is hollow inside, and the fixed flange 6 and mounting flange 7 are equipped with flow channels 8, through which the medium can flow. The rubber inner liner 9 is installed inside the steel outer shell 5, forming an air chamber 10 between the inner liner 9 and the steel outer shell 5. The air vent pipe 11 connects to the air chamber 10. When the air chamber 10 is inflated, the rubber inner liner 9 expands to block the flow channels 8. When the air is deflated, the rubber inner liner 9 contracts to open the channels. When inflating, the air is connected to the air source to pressurize the air chamber 10 through the air vent pipe 11. When deflated, the gas in the air chamber 10 is released through the air vent pipe 11. The outer shell and other components are integrally formed, resulting in excellent sealing performance and structural strength. The air control method of rubber inner liner 9 + air chamber 10 eliminates the need for vertical movement, is suitable for low-profile well chambers, and replaces complex mechanical or hydraulic transmissions. It has a low failure rate, low cost, and can also operate submerged in water.

[0027] Example 2:

[0028] Please see Figure 1-4 The present invention provides a technical solution based on embodiment one: the top of the steel outer shell 5 is provided with a set of lifting blocks 20, the lifting blocks 20 are rectangular in shape and the top two corners are arc-shaped, the bottom of the lifting blocks 20 are arc-shaped, and the surface of the lifting blocks 20 is provided with lifting holes 21.

[0029] Analysis of the above content: The lifting block 20 on the top of the steel shell 5 uses the lifting holes 21 opened on its surface to cooperate with the lifting equipment to lift and position the airbag valve device 2. During construction, the lifting rope is passed through the lifting holes 21 to lift the device to the installation position and adjust it into place. The rectangular shape and rounded corner design of the lifting block 20 makes the structure stable and easy to hang ropes; the lifting holes 21 make the lifting operation more convenient, reduce the installation difficulty and improve the construction efficiency.

[0030] Example 3:

[0031] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The right end of the mounting flange 7 is provided with a flange seat 12. The flange seat 12 has a square shape and a hollow structure in the middle. The top, left end and right end of the flange seat 12 are provided with several sets of large locking blocks 13. The large locking blocks 13 have a rectangular shape and a through structure inside. The surface of the large locking blocks 13 is provided with locking holes 17. The top of the flange seat 12 is provided with several sets of wedge-shaped hooks 14 distributed horizontally at equal intervals. The wedge-shaped hooks 14 have an L-shaped structure. The several sets of wedge-shaped hooks 14 and the several sets of large locking blocks 13 are distributed in an alternating manner.

[0032] Analysis of the above: The flange seat 12 on the right end of the mounting flange 7 is a hollow square structure. The large locking blocks 13 (internal through-hole with locking holes 17) at the top, left, and right ends of the flange seat 12 cooperate with the small locking blocks 15 of the mounting device 3. The L-shaped wedge hooks 14 at the top are staggered with the large locking blocks 13, which can assist in pre-positioning during installation, so that the locking holes 17 of the large locking blocks 13 and the small locking blocks 15 are aligned. During installation, the flange seat 12 is first pre-attached to the fixed base 22 of the mounting device 3 through the wedge hooks 14, and then the bolts are inserted into the locking holes 17 of the large locking blocks 13 and the small locking blocks 15 and tightened. The staggered distribution of the large locking blocks 13 and the wedge hooks 14 not only improves the connection stability but also simplifies the installation alignment process. The through-hole design of the locking holes 17 makes the bolt connection more secure.

[0033] Example 4:

[0034] Please see Figure 1-4This utility model provides a technical solution based on Embodiment 1: The installation device 3 includes a fixed base 22, small locking blocks 15, and wedge-shaped blocks 16. The fixed base 22 has a square shape. Several sets of small locking blocks 15 are provided, and the several sets of small locking blocks 15 are respectively welded to the top, right end, and left end of the fixed base 22. The small locking blocks 15 have a rectangular shape and a hollow interior. Locking holes 17 are also provided on the surface of the small locking blocks 15. The small locking blocks 15 are connected to the large locking blocks 13 by bolts and nuts. Several sets of small fixing rings 18 are provided on the front side of the top, front side of the left end, front side of the right end, and front side of the bottom of the fixed base 22. The small fixing rings 18 have a semi-circular shape.

[0035] Analysis of the above: The fixed base 22 of the mounting device 3 is bolted to the large locking block 13 of the flange seat 12 via multiple sets of small locking blocks 15, thereby fixing the airbag valve device 2; the small fixing ring 18 on the front side of the fixed base 22 can be used for additional auxiliary fixing (such as binding reinforcement); the sealing ring 19 between the flange seat 12 and the fixed base 22 enhances the seal, and the bolts are inserted into the locking holes 17 of the small locking blocks 15 and the large locking blocks 13 and tightened; if reinforcement is required, reinforcement is bound to the small fixing ring 18; the sealing ring 19 is placed between the mating surfaces of the flange seat 12 and the fixed base 22, and the compression seal is achieved by bolt tightening. Multiple sets of small locking blocks 15 and large locking blocks 13 are distributed, resulting in uniform force distribution and strong stability; the small fixing ring 18 provides additional fixing points to adapt to complex working conditions; the sealing ring 19 improves the sealing performance of the connection and prevents media leakage.

[0036] Example 5:

[0037] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: a sealing ring 19 is provided between the flange seat 12 and the fixed base 22.

[0038] Analysis of the above content: When the large locking block 13 and the small locking block 15 are tightened by bolts, the sealing ring 19 between the flange seat 12 and the fixed base 22 is squeezed and deformed to fill the gap, blocking the leakage path of the medium. During installation, the sealing ring 19 is placed between the mating surfaces of the flange seat 12 and the fixed base 22, and then the bolts are tightened to compress and seal the sealing ring. The sealing ring 19 provides additional sealing protection for the connection between the flange seat 12 and the fixed base 22, avoiding leakage caused by machining errors or vibration under operating conditions, and improving the overall sealing reliability.

[0039] Working principle: The airbag valve device 2 is fixed to the well chamber pipeline by the hoisting device 4 and the installation device 3 (which is pre-positioned by bolts of large locking block 13 and small locking block 15 and wedge hook 14, and sealed with sealing ring 19). During operation, air is injected into the air chamber 10 between the steel outer shell 5 and the rubber inner liner 9 through the air hole pipe 11, causing the rubber inner liner 9 to expand and block the flow passage 8 inside the fixing flange 6 and the installation flange 7, thereby cutting off the medium. When the gas in the air chamber 10 is released, the rubber inner liner 9 contracts and the flow passage 8 is restored to conduction, thus completing the on- and off-circuit control of the pipeline medium. The integrated steel outer shell 5 and other structures, the air control method and various auxiliary installation structures together ensure its efficient and stable operation in the confined well chamber environment.

[0040] The components of this utility model are: 1. Device body; 2. Airbag valve device; 3. Installation device; 4. Lifting rod device; 5. Steel outer shell; 6. Fixed flange; 7. Mounting flange; 8. Flow channel; 9. Rubber inner liner; 10. Air chamber; 11. Air hole pipe; 12. Flange seat; 13. Large locking block; 14. Wedge hook; 15. Small locking block; 16. Wedge block; 17. Locking hole; 18.

All components are general standard parts or parts known to those skilled in the art, and their structure and principles can be obtained by those skilled in the art through technical manuals. As known or as discovered through conventional experimental methods, the problem solved by this utility model is that the gates commonly used for cutting off the inlet and outlet of pipes inside manholes have large space requirements (a certain amount of space is needed vertically or horizontally, making them unusable in confined environments) and defects in transmission methods (high failure rate of electric screw transmission, inability to be submerged in water, long transmission distance, and expensive hydraulic transmission). This utility model, through the combination of the above-mentioned components, eliminates the vertical movement space required by traditional gates and can perfectly adapt to the environment of low manholes; by using a pneumatic control method to replace electric screw or hydraulic transmission, not only is the failure rate greatly reduced, but it can also work submerged in water, and the cost is far lower than that of hydraulic transmission systems.
