[0002] The existing pneumatic shuttle valve controls the entry and exit of the air source through the air inlet on the valve body. The piston reciprocates, thereby controlling the valve opening and closing. It is also convenient to install the pneumatic shuttle valve on the water pipe to control the flow of water, realize the opening or closing of the water circuit, and use the detection hole installed at the bottom to periodically detect internal leaks.

[0003] Existing pneumatic shuttle valves are directly fixed to water pipes via threaded structures or flanges. Therefore, after one end of the valve is threaded to a water pipe, the other end is too long, making it inconvenient to reconnect to another pipe. Alternatively, installation via flanges requires multiple bolts, which is cumbersome and slows down installation. Furthermore, disassembly is inconvenient when the valve is damaged, affecting the ease of installation, use, disassembly, and repair. To address these issues, this invention proposes a pneumatic shuttle valve with leakage detection functionality. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a pneumatic shuttle valve with leakage detection function, including a pneumatic shuttle valve body 100, the pneumatic shuttle valve body 100 including a valve body 101, an installation inlet 105 and an installation outlet 102 respectively opened on both sides of the valve body 101, a leakage detection hole 106 opened at the bottom end of the valve body 101, a plunger 107 threadedly connected inside the leakage detection hole 106, an adjustment mechanism 103 installed at the top end of the valve body 101, an air inlet 104 provided on the side of the adjustment mechanism 103, and the pneumatic shuttle valve body 100 also has:

[0026] The convenient disassembly and assembly mechanism includes a pulling component located at the edge of the installation outlet 102 and the installation inlet 105. The end of the pulling component is provided with a compression reinforcement component on the inner surface of the installation outlet 102 and the installation inlet 105. A rotation pulling component is provided on the upper surface of the pulling component. A sealing installation component is provided at the inner bottom of the installation outlet 102 and the installation inlet 105. The pneumatic shuttle valve body 100 can be quickly disassembled and assembled during installation and use through the convenient disassembly and assembly mechanism, and the disassembly and assembly operation is simple and convenient.

[0027] In order to facilitate the use of the pull assembly to pull and press the trapezoidal block 1029 onto the surface of the inner tooth reinforcement plate 1025 for reinforcement, in this embodiment, preferably, the pull assembly includes a push groove 1028 formed at the edges of the installation outlet 102 and the installation inlet 105 located inside the valve body 101. The trapezoidal block 1029 is limited inside the push groove 1028, and a limit block 1020 is fixed on one side of the trapezoidal block 1029. This facilitates the sliding of the trapezoidal block 1029 inside the push groove 1028 and the pressing of the trapezoidal block 1029 against the bottom end of the inner tooth reinforcement plate 1025 for reinforcement and installation.

[0028] To facilitate the compression reinforcement installation of the inlet and outlet pipes after closure using the compression reinforcement component, in this embodiment, preferably, the compression reinforcement component includes an adjustment groove 1024 formed on the inner surface of the installation outlet 102 and the installation inlet 105 on one side of the push groove 1028. An inner tooth reinforcement plate 1025 is limited inside the push groove 1028 extending from the adjustment groove 1024. The end of the inner tooth reinforcement plate 1025 matches the surface structure of one side of the trapezoidal block 1029, allowing the inner tooth reinforcement plate 1025 to be limited and moved inside the adjustment groove 1024, so that the inner tooth reinforcement plate 1025 is fixedly installed on the outer surface of the pipe by limiting and moving.

[0029] To facilitate the compression and reinforcement installation of the internal toothed reinforcing plate 1025 via a rotating pull assembly, in this embodiment, preferably, the rotating pull assembly includes an internal threaded groove 1023 formed on the surface of the valve body 101. An external threaded pressure ring 1021 is threadedly connected to the internal threaded groove 1023. A rotating arc-shaped plate 1027 is rotatably connected to the lower surface of the external threaded pressure ring 1021 via an annular groove. A push rod 1026 is integrally provided on the lower surface of the rotating arc-shaped plate 1027. The bottom end of the push rod 1026 is fixed to the upper surface of the trapezoidal block 1029 by screws. When the external threaded pressure ring 1021 is rotated and installed, the push rod 1026 can pull the trapezoidal block 1029, and the trapezoidal block 1029 can be pulled and pressed against the surface of the internal toothed reinforcing plate 1025 for compression reinforcement installation of the pipeline, which facilitates compression reinforcement.

[0030] In order to facilitate the sealing and reinforcement of the ends of the inlet and outlet pipes inside the installation outlet 102 and installation inlet 105 by means of a sealing installation assembly, in this embodiment, preferably, the sealing installation assembly includes a sealing gasket 1022 that is snapped into the bottom of the installation outlet 102 and installation inlet 105, and the sealing gasket 1022 has a ring structure, which facilitates the sealing and fixing of the ends of the water inlet pipe and the water outlet pipe after they are closed inside the installation inlet 105 and installation outlet 102.

[0031] The reinforcement installation mechanism includes a fixed installation component located on the outer surface of the plunger 107 at the bottom of the valve body 101. The inner surface of the fixed installation component is provided with a rotating reinforcement component. After the plunger 107 is rotated and reinforced in the internal thread of the leakage detection hole 106, the reinforcement installation mechanism can reinforce the plunger 107 again. This makes it less likely to loosen when subjected to water pressure.

[0032] In order to facilitate the rotation and compression reinforcement installation of the external threaded reinforcing ring 1073 by means of a fixed installation component, in this embodiment, preferably, the fixed installation component includes an internal threaded ring 1071 fixedly installed at the bottom end of the valve body 101 on the edge of the leakage detection hole 106 by screws, so as to facilitate the rotation and adjustment reinforcement installation inside the internal threaded ring 1071.

[0033] To facilitate the rotational compression reinforcement of the plunger 107 using the rotational reinforcement assembly, in this embodiment, preferably, the rotational reinforcement assembly includes an external threaded reinforcement ring 1073 that rotates inside the internal threaded ring 1071 via a threaded structure. The inner surface of the external threaded reinforcement ring 1073 has a beveled structure 1072. The bottom edge of the plunger 107 is fixed with a beveled ring 1074, and the outer surface of the beveled ring 1074 is in compression contact with the inner surface of the beveled structure 1072. After the plunger 107 is installed, the external threaded reinforcement ring 1073 can rotate inside the internal threaded ring 1071. When rotating the external threaded reinforcement ring 1073, the surface of the beveled ring 1074 contacts the beveled structure 1072 to compress and reinforce the plunger 107, facilitating fixed installation and use.

[0034] The working principle and usage process of this utility model: Before use, the pneumatic shuttle valve with leakage detection function is first fixedly installed. During installation, the plunger 107 is threaded into the inside of the leakage detection hole 106 for sealing. After installation, the installation inlet 105 is connected to the external water inlet pipe, and the installation outlet 102 is connected to the external drain pipe, thereby fixing the pneumatic shuttle valve body 100 on the water pipe. At the same time, air is introduced through the air inlet 104, which makes it easy to install the pneumatic shuttle valve body 100 on the water pipe. When the pneumatic shuttle valve body 100 leaks internally after long-term use after fixed installation, the plunger 107 can be removed from the inside of the leakage detection hole 106, and the internal leakage of the valve body 101 can be detected through the leakage detection hole 106.

[0035] Then, before the pneumatic shuttle valve body 100 is fixedly installed and used, after the plunger 107 is fixedly installed, the external thread reinforcing ring 1073 can be connected to the internal thread of the internal thread ring 1071. When the external thread reinforcing ring 1073 rotates, it presses the surface of the contact inclined ring 1074 through the internal inclined structure 1072 to press and reinforce the plunger 107, which facilitates the reinforcement and installation of the plunger 107. Moreover, when the pneumatic shuttle valve body 100 is installed and used, the plunger 107 is reinforced and installed, and it is not easy to loosen and leak when subjected to internal water pressure, thus improving the reinforcement and fixation of the plunger 107 by the pneumatic shuttle valve body 100 during installation and use.

[0036] Finally, when the pneumatic shuttle valve body 100 is installed and used, the external water inlet pipe and water outlet pipe can be embedded into the installation inlet 105 and installation outlet 102 respectively, and sealed in contact with the surface of the sealing gasket 1022. Then, rotate the external thread pressure ring 1021 inside the internal thread groove 1023. When rotating the external thread pressure ring 1021 outwards, the rotating arc plate 1027 rotates in place inside the external thread pressure ring 1021. The rotating arc plate 1027 also pulls the push rod 1026 and trapezoidal block 1029, placing the trapezoidal block 1029 inside the push groove 1028, where the limiting block 1020 controls the trapezoidal block 1029. The 29-position sliding limit causes the end of the trapezoidal block 1029 to contact the surface of the internal tooth reinforcement plate 1025 and press it, thus squeezing and moving the internal tooth reinforcement plate 1025. This allows the internal tooth reinforcement plate 1025 to move inside the adjusting groove 1024 and be pressed and reinforced on the outer surface of the external pipe. This facilitates the simultaneous movement and reinforcement of the four internal tooth reinforcement plates 1025 when rotating the external thread pressure ring 1021, making it convenient for fixed installation. Therefore, in case of damage during use, the reverse operation is convenient for disassembly and maintenance. This improves the convenience of disassembly and maintenance when the air-controlled shuttle valve body 100 is damaged after installation with the external inlet and outlet water pipes.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
