Description

Technical Field

[0001] This utility model relates to the field of pneumatic solenoid valve technology, specifically to a leak-proof pneumatic solenoid valve. Background Technology

[0002] A pneumatic solenoid valve is a type of valve that uses electromagnetic force to control the flow of gas. It is a key component in pneumatic systems, mainly used for automated control of gas switching, flow direction, or flow rate, and is widely used in industrial automation, mechanical control, production line equipment, robot control systems, and other fields.

[0003] During use, the connection between the pneumatic solenoid valve and the external hose is exposed to the outside for a long time, which may be affected by environmental factors such as temperature, humidity, ultraviolet rays, and chemical corrosion, which can easily lead to leakage at the connection. To address this problem, a leak-proof pneumatic solenoid valve is needed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a leak-proof pneumatic solenoid valve to solve the technical problem that leakage is easily caused at the connection between the pneumatic solenoid valve and the external hose.

[0005] To achieve the above objectives, this utility model provides a leak-proof pneumatic solenoid valve, including a solenoid valve body having a threaded connector. The leak-proof pneumatic solenoid valve also includes a sleeve disposed at the threaded connector, and a screw ring is provided on the sleeve for connecting a hose to the sleeve.

[0006] Preferably, the sleeve includes a central wall, and a connector sleeve is provided on one side of the central wall for connection with a threaded connector.

[0007] Preferably, an inner cylinder and an outer cylinder are provided on the other side of the neutral wall, the inner cylinder is connected to the connector cylinder, and the diameter of the outer cylinder is larger than that of the inner cylinder.

[0008] Preferably, the screw ring includes a ring joint and a tapered sleeve disposed at one end of the ring joint, and the outer wall of the ring joint is provided with a threaded groove for threaded connection with the outer cylinder.

[0009] The inner diameter of the conical sleeve gradually increases near the annular joint, and the conical sleeve has a notch around its axis.

[0010] Preferably, the screw ring further includes a grip ring disposed at the other end of the ring joint, the outer diameter of the grip ring being larger than that of the outer cylinder, and the outer edge surface of the grip ring forming a raised friction surface.

[0011] Preferably, the leak-proof pneumatic solenoid valve further includes a rotating ring, which is rotatably mounted between the outer cylinder and the connector cylinder via a bearing. A limit rod is provided on the rotating ring, and the end of the limit rod passes through the grip ring and is provided with a limit nut.

[0013] Preferably, the filter layer includes a ring, the inner edge of which is provided with a filter screen, and rubber rings are provided on both sides of the ring.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a rotating grip to screw the ring joint to the outer cylinder. During the screwing process, the conical sleeve continuously approaches the central wall. Since the inner diameter of the conical sleeve gradually increases as it approaches the ring joint, the hose will be continuously tightened to the outer wall of the inner cylinder as the conical sleeve moves, thus solving the problem of leakage at the connection between the pneumatic solenoid valve and the external hose.

[0026] This utility model proposes a leak-proof pneumatic solenoid valve, such as... Figures 1 to 5 As shown, the device includes a solenoid valve body 1, which has a threaded connector 11. The leak-proof pneumatic solenoid valve also includes a sleeve 2 disposed at the threaded connector 11. The sleeve 2 is provided with a screw ring 3 for connecting the hose 6 to the sleeve 2.

[0029] Furthermore:

[0030] An inner cylinder 23 and an outer cylinder 24 are provided on the other side of the central wall 21. The inner cylinder 23 is connected to the connector cylinder 22, and the diameter of the outer cylinder 24 is larger than that of the inner cylinder 23.

[0031] Furthermore:

[0032] The screw ring 3 includes a ring joint 31 and a tapered sleeve 32 disposed at one end of the ring joint 31. The outer wall of the ring joint 31 is provided with a threaded groove that is threadedly connected to the outer cylinder 24.

[0033] The inner diameter of the tapered sleeve 32 gradually increases near the annular joint 31, and the tapered sleeve 32 has a notch 321 around its axis.

[0034] Furthermore:

[0035] The screw ring 3 also includes a grip ring 33 disposed at the other end of the ring joint 31. The outer diameter of the grip ring 33 is larger than that of the outer cylinder 24, and the outer edge surface of the grip ring 33 forms a raised friction surface.

[0036] Furthermore:

The ring 33 is held and rotated so that the ring joint 31 is screwed with the outer cylinder 24. During the screwing process, the conical sleeve 32 continuously approaches the central wall 21.
