Technical Field

[0001] This utility model relates to the field of pneumatic valve technology, specifically a manual / automatic integrated pneumatic valve designed to prevent accidental switching. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems, among which pneumatic valves utilize compressed air to drive multiple sets of combined pneumatic pistons within the actuator.

[0003] Existing pneumatic valves are prone to accidental activation during actual use, which can lead to unexpected start-up or closure, causing unnecessary obstruction or damage to the flow of objects inside the pipe. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a manual / automatic integrated pneumatic valve that prevents accidental switching, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual / automatic integrated pneumatic valve for preventing accidental switching, comprising a pipe body, a valve seat mounted on the outer surface of the pipe body near the top via a connecting column, and mounting columns mounted on both sides of the top of the valve seat, the tops of the mounting columns being mounted to the bottom of a cylinder, and a push rod mounted on the bottom of the cylinder near the middle, the push rod having a limit hole inside, a sliding groove formed on one side of the top of the valve seat, and a support rod mounted on the side of the top of the valve seat near the sliding groove, the top of the support rod having an arc-shaped plate mounted on it, and a limit mechanism mounted on the front side of the valve seat near the middle, the limit mechanism including a mounting plate.

[0006] Preferably, an electric telescopic rod is installed on one side of the mounting plate near the top, and a mounting plate is installed at one end of the electric telescopic rod, with a limit rod installed at one end of the mounting plate.

[0007] Preferably, an installation ring is fitted onto one end of the outer surface of the electric telescopic rod, and a sliding rod is installed on the side surface of the installation ring.

[0008] Preferably, the outer diameter of the limiting rod is adapted to the inner diameter of the limiting hole, and one end of the limiting rod passes through the limiting hole into the interior of the push rod.

[0009] Preferably, the bottom end of the slide rod is located inside the slide groove, and the bottom end of the slide rod is slidably connected to the inside of the slide groove.

[0010] Preferably, the arc-shaped plate is arc-shaped, and the inner wall of the arc-shaped plate is fitted to the outer surface of the electric telescopic rod.

[0011] Preferably, the bottom side of the mounting plate is installed opposite the front side of the valve seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as limiting holes, sliding grooves, support rods, arc-shaped plates, mounting plates, electric telescopic rods, mounting rings, sliding rods, mounting discs, and limiting rods, the problem of accidental activation of existing pneumatic valves during actual use can be effectively solved. This can lead to unintended start-up or closure of the pneumatic valve, causing unnecessary obstruction or loss of the flow of objects inside the pipe.

[0014] The user can start the electric telescopic rod, causing the mounting plate to move to one side. This movement of the electric telescopic rod causes the limiting rod to move to one side as well, allowing one end of the limiting rod to pass through the limiting hole and engage with the push rod in a movable limiting engagement. As one end of the electric telescopic rod moves to one side, the mounting ring also moves to one side, causing the sliding rod to move accordingly. This allows the bottom end of the sliding rod to move within the sliding groove, making the movement of one end of the electric telescopic rod more stable and less prone to wobbling. The limiting rod then engages the push rod in a limiting engagement. If the user accidentally touches the cylinder's start button, one end of the push rod will not move downwards. At this point, the cylinder and push rod will malfunction and an alarm will sound. The user can immediately shut off the cylinder. The above-mentioned components and their operation prevent accidental start-up. Attached Figure Description

[0020] 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.

[0021] according to Figures 1-4 As shown, the device includes a pipe body 1. A valve seat 12 is installed on the outer surface of the pipe body 1 near the top end via a connecting column 11. Mounting columns 13 are installed on both sides of the top end of the valve seat 12. The top ends of the mounting columns 13 are installed with the bottom end of the cylinder 14. A push rod 15 is installed near the middle of the bottom end of the cylinder 14. A valve is installed at the bottom end of the push rod 15 via a connecting rod. The valve is located inside the pipe body 1 and can control the opening or closing state of the pipe body 1. A limit hole 16 is opened inside the push rod 15. A sliding groove 17 is opened on one side of the top end of the valve seat 12. A support rod 18 is installed on the side of the top end of the valve seat 12 near the sliding groove 17. An arc plate 19 is installed on the top end of the support rod 18. The arc plate 19 is arc-shaped and its inner wall is fitted with the outer surface of the electric telescopic rod 22.

[0022] A limiting mechanism 2 is installed on the center side of the valve seat 12. The limiting mechanism 2 includes a mounting plate 21. The bottom side of the mounting plate 21 is installed opposite the front side of the valve seat 12. An electric telescopic rod 22 is installed on the top side of the mounting plate 21. A mounting plate 25 is installed on one end of the electric telescopic rod 22. A limiting rod 26 is installed on one end of the mounting plate 25. A mounting ring 23 is fitted on one end of the outer surface of the electric telescopic rod 22. A sliding rod 24 is installed on the side surface of the mounting ring 23. The bottom end of the sliding rod 24 is located inside the sliding groove 17 and is slidably connected to the inside of the sliding groove 17. The outer diameter of the limiting rod 26 is matched with the inner diameter of the limiting hole 16, and one end of the limiting rod 26 passes through the limiting hole 16 and enters the inside of the push rod 15.

[0023] In use, the user can start the electric telescopic rod 22. Under the operation of the electric telescopic rod 22, the mounting plate 25 can move to one side, causing the limiting rod 26 to move to one side as well. One end of the limiting rod 26 can pass through the limiting hole 16 and be engaged with the push rod 15 in a movable limiting engagement. Simultaneously, as one end of the electric telescopic rod 22 moves to one side, the mounting ring 23 also moves to one side, causing the sliding rod 24 to move accordingly. This allows the bottom end of the sliding rod 24 to move within the sliding groove 17, making the movement of one end of the electric telescopic rod 22 more stable and less prone to wobbling. At this point, it is possible to... The push rod 15 is limited and locked by the limit rod 26. If the user accidentally touches the start button of the cylinder 14, one end of the push rod 15 cannot move downward. At this time, the cylinder 14 and the push rod 15 cannot operate normally and will sound an alarm. At this time, the user can shut down the cylinder 14 immediately. Through the above-mentioned components, the function of preventing accidental start can be achieved. Since the top of the support rod 18 is equipped with an arc plate 19, the arc plate 19 is arc-shaped and its inner wall is in contact with the outer surface of the electric telescopic rod 22. Thus, the support rod 18 and the arc plate 19 can support the electric telescopic rod 22, so that the electric telescopic rod 22 can be stably installed on one side of the limit mechanism 2.
