[0022] A position sensing mechanism includes a mounting assembly, a movable connection assembly, a sealing assembly and a position sensing assembly. The mounting assembly is arranged at both ends of the main mounting tube 101, the movable connection assembly is arranged inside the main mounting tube 101, and the sealing assembly and the position sensing assembly are both arranged on the outer surface of the movable connection assembly. When the air-controlled shuttle valve body 100 is in use and dirt enters the interior or the sealing ring 1018 is stuck, the position sensing mechanism can sense the position of the piston 1016, so that the switch state of the air-controlled shuttle valve body 100 can be known in time, thereby improving the convenience of sensing the position of the piston 1016 when the air-controlled shuttle valve body 100 is installed and used.

[0023] In order to facilitate the installation operation of the air-controlled shuttle valve body 100 through the installation assembly and connect the air-controlled shuttle valve body 100 to the external pipeline, in this embodiment, preferably, the installation assembly includes a mounting body 1011 and a mounting body 1012 respectively arranged at both ends of the main mounting cylinder 101, and the mounting threaded rod 102 passes through the corner position of the mounting body 1011 and the mounting body 1012. The mounting body 1011, the mounting body 1012 and the main mounting cylinder 101 are fixedly connected through the mounting threaded rod 102, and the mounting body 1011 and the mounting body 1012 can be respectively engaged with the main mounting cylinder 101. 1 is connected to the end of the main installation tube 101 by the second installation body 1012 for fixed installation. The outer surfaces of the first installation body 1011 and the second installation body 1012 are fitted with two sealing rings, and the first installation body 1011, the second installation body 1012 and the interior of the main installation tube 101 are sealed and connected through the sealing rings, so that the first installation body 1011 and the second installation body 1012 are sealed and installed at the end of the main installation tube 101. A connecting port is opened at the edge of the end of the second installation body 1012, and the inner surface of the connecting port is an arc-shaped structure, so that when the piston 1016 is opened, the fluid is discharged through the connecting port at the edge of the second installation body 1012.

[0024] In order to facilitate opening or closing of the air-controlled shuttle valve body 100 when in use through the movable connection assembly, in this embodiment, preferably, the movable connection assembly includes a piston 1016 arranged inside the main mounting cylinder 101, and a spring 1015 is installed on the outer surface of one end of the piston 1016. The end of the piston 1016 is tightly pressed and sealed with the end surface of the mounting body 1011. The piston 1016 can be opened when the spring 1015 is compressed, and vice versa. The piston 1016 is tightly pressed and closed. In order to facilitate opening or closing of the piston 1016 through the sealing assembly, 16 always seals and separates the two ends of the interior of the main installation cylinder 101 during movement. The sealing component includes a mounting groove D1010 opened on the outer surface of the piston 1016. A sealing ring 1018 is installed inside the mounting groove D1010, and the outer surface of the piston 1016 and the inner surface of the main installation cylinder 101 are sealed and connected via the sealing ring 1018. The sealing ring 1018 can be installed inside the mounting groove D1010, and the piston 1016 is always sealed and connected via the sealing ring 1018 when it moves inside the main installation cylinder 101.

[0025] In order to facilitate sensing the position of the piston 1016 through the position sensing component, in the present embodiment, preferably, the position sensing component includes a mounting groove C1019 opened on the outer surface of the piston 1016 and located on one side of the mounting groove D1010, and a magnetic ring 1017 is installed in the inner sleeve of the mounting groove C1019. A sensing switch A1013 is fixedly installed on one end of the main mounting cylinder 101 by screws, and a sensing switch B1014 is fixedly installed on the other end of the main mounting cylinder 101 by screws. When the piston 1016 moves and drives the magnetic ring 1017 to move, the sensing switch B1014 receives a signal from the magnetic ring 1017, which is a signal that the piston 1016 is open, and it is convenient to know that the piston 1016 is in the open position. On the contrary, the piston 1016 drives the magnetic ring 1017 to move, and the sensing switch A1013 at the other end receives a signal from the magnetic ring 1017, which is a signal that the piston 1016 is closed.

[0026] Working principle and use process of the utility model: when using the air-controlled shuttle valve, first install the installation body 1011 and the installation body 2 1012 with the external pipeline, and install the air-controlled shuttle valve body 100 on the pipeline for use. When it is installed and used, when flow is needed, the air is taken in from the inside of the air inlet 103 and enters the inside of the main installation cylinder 101. The gas enters the spring 1015 and is compressed to drive the piston 1016 to move. When the piston 1016 moves inside the main installation cylinder 101, the sealing ring 1018 contacts the inner surface of the main installation cylinder 101 and is always sealed and connected until the piston 1016 moves to separate the end of the piston 1016 from the surface of the installation body 2 1012, and the fluid is discharged through the connection port at the edge of the installation body 2 1012. When the end of the piston 1016 is separated from the surface of the installation body 2 1012, the fluid is discharged from the connection port at the edge of the installation body 2 1012. When the piston 1016 is separated from the surface of the second mounting body 1012, the movement of the piston 1016 drives the movement of the magnetic ring 1017. The signal received by the induction switch B1014 from the magnetic ring 1017 is a signal that the piston 1016 is open, and it is convenient to know that the piston 1016 is in the open position. On the contrary, the end of the piston 1016 is pressed against the surface of the second mounting body 1012 to drive the movement of the magnetic ring 1017. The signal received by the induction switch A1013 at the other end is a signal that the piston 1016 is closed. Therefore, when the magnetic ring 1017 is damaged or stuck by dirt in the air-controlled shuttle valve body 100, it is convenient to sense the position of the piston 1016, and the switch state of the air-controlled shuttle valve body 100 can be known in time, thereby improving the convenience of sensing the position of the piston 1016 when the air-controlled shuttle valve body 100 is installed and used.
