Abstract

This utility model provides a safety interlock device for a track ball valve, relating to the field of track ball valve technology, including a mounting base. A threaded hole is provided at the upper front end of the mounting base, and a locking bolt is rotatably connected within the threaded hole. By limiting the movement of the adjusting rod through the engagement of the locking bolt, the rotation of the track ball valve's adjusting rod is directly restricted, preventing accidental opening or closing of the ball valve due to accidental contact with the adjusting rod. This fundamentally reduces the risk of material leakage and safety accidents. The transmission component can automatically reset under the action of the spring component. After its hexagonal insert disengages from the hexagonal groove of the locking bolt, even accidental contact with the transmission component cannot drive the locking bolt to rotate, further preventing accidental release of the locking state, thus providing double protection for interlock reliability. This solves the problem that in existing track ball valve applications, accidental contact with the operating position of the track ball valve can lead to material leakage, potentially causing a safety accident.

Description

Technical Field

[0001] This utility model belongs to the field of track ball valve technology, and more specifically, it relates to a safety interlock device for track ball valves. Background Technology

[0002] Ball valves and gate valves belong to the same type of valve, the difference being that the ball valve's closing element is a ball. The ball rotates around the valve body's centerline to open and close the valve. Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media. They are a relatively new type of valve that has been widely adopted in recent years.

[0003] Understanding the application of existing track ball valves: If the operating position of the track ball valve is accidentally touched during use, it will cause material leakage, which may lead to a safety accident. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a safety interlock device for a track ball valve, which solves the problem that if the operating position of the track ball valve is accidentally touched during its use, it will lead to material leakage, which may cause a safety accident once leakage occurs.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A safety interlock device for a track ball valve includes a mounting base. A threaded hole is provided at the upper front end of the mounting base, and a locking bolt is rotatably connected within the threaded hole. A hexagonal groove is provided at the front end of the locking bolt. A protective frame is fixedly mounted at the upper front end of the mounting base, positioned directly in front of the locking bolt. The protective frame has a hollow interior and a sliding hole at its front end. The sliding hole of the protective frame is slidably connected to the middle position of a transmission component. A circular stop is provided at the front end of the transmission component, and a hexagonal insert is provided at its rear end. The transmission component is positioned directly in front of the locking bolt. A spring is sleeved on the front middle of the transmission component, with its front end fitting against the rear of the circular stop and its rear end fitting against the front end of the protective frame.

[0007] According to one embodiment of the present invention, a track ball valve body is fixedly installed inside the mounting base, and an adjusting rod is rotatably connected to the top of the track ball valve body. The adjusting rod is fixedly connected to the top of the ball valve inside the track ball valve body.

[0008] According to one embodiment of the present invention, an additional mounting plate is fixedly connected to the front and rear ends of the top of the mounting base, and a semi-circular groove is provided in the middle of the two additional mounting plates, and the adjusting rod is located in the semi-circular groove of the two additional mounting plates.

[0009] According to one embodiment of the present invention, the front end of the adjusting rod is aligned with the rear end of the locking bolt, and the rear end of the locking bolt is in contact with the adjusting rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By locking the bolt and adjusting the rod together, the rotation of the adjusting rod of the track ball valve can be directly restricted, avoiding accidental opening or closing of the ball valve due to accidental contact with the adjusting rod. This reduces the risk of material leakage and safety accidents from the source. The transmission component can automatically reset under the action of the spring component. After the hexagonal pin disengages from the hexagonal groove of the locking bolt, even if the transmission component is accidentally contacted, it cannot drive the locking bolt to rotate, further preventing the locking state from being accidentally released, thus providing double protection for the reliability of the interlock.

[0012] 2. The protective frame is hollow and has sliding holes, which not only provides sliding guidance for the transmission components, but also provides physical protection for the locking bolts and transmission components, reducing the interference of external factors on the core components.

[0013] 3. The transmission component and the protective frame are slidably connected. With the elasticity of the spring component, locking and unlocking operations can be completed simply by pressing the transmission component and rotating it. The operation process is simple and easy for staff to operate quickly. Moreover, the connection of each component is stable and it is not easy to jam or fail after long-term use.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a safety interlocking device for a track ball valve, including a mounting base 1; a threaded hole is provided at the upper front end of the mounting base 1, and a locking bolt 102 is rotatably connected in the threaded hole of the mounting base 1. A hexagonal groove is provided at the front end of the locking bolt 102. A protective frame 103 is fixedly installed at the upper front end of the mounting base 1. The protective frame 103 is located directly in front of the locking bolt 102. The interior of the protective frame 103 is hollow, and a sliding hole is provided at the front end of the protective frame 103. The sliding hole of the protective frame 103 is slidably connected to the middle position of the transmission component 104. A circular stop is provided at the front end of the transmission component 104, and a hexagonal insert is provided at the rear end of the transmission component 104. The transmission component 104 is located directly in front of the locking bolt 102. A spring component 105 is sleeved on the front middle of the transmission component 104. The front end of the spring component 105 is attached to the rear of the circular stop of the transmission component 104, and the rear end of the spring component 105 is attached to the front end of the protective frame 103.

[0026] The mounting base 1 has a fixedly installed track ball valve body 2 inside, and an adjusting rod 201 is rotatably connected to the top of the track ball valve body 2. The adjusting rod 201 is fixedly connected to the top of the ball valve inside the track ball valve body 2.

[0027] The mounting base 1 has an additional plate 101 fixedly connected to the front and rear ends of the top. The two additional plates 101 have a semi-circular groove in the middle. The adjusting rod 201 is located in the semi-circular groove of the two additional plates 101. The front end of the adjusting rod 201 is aligned with the rear end of the locking bolt 102, and the rear end of the locking bolt 102 is in contact with the adjusting rod 201.

[0028] When using:

[0029] First, install the mounting base 1 on the outer side of the track ball valve body 2, and rotate the adjusting rod 201 to adjust the track ball valve body 2;

[0030] When it is necessary to lock the adjusting rod 201, firstly, the transmission component 104 is slid and pressed backward in the sliding hole of the protective frame 103. At this time, the spring component 105 retracts, and at the same time, the hexagonal insert at the rear end of the transmission component 104 is inserted into the hexagonal groove of the locking bolt 102. Then, the transmission component 104 is rotated, and the locking bolt 102 is rotated and adjusted by the transmission component 104. The locking bolt 102 is engaged with the threaded hole above the front end of the mounting base 1, so that the locking bolt 102 moves backward until the rear end of the locking bolt 102 is in contact with the adjusting rod 201, and the rotation of the adjusting rod 201 is limited to avoid accidental contact.

[0031] After the locking adjustment lever 201 is engaged, and the operator does not press or contact the transmission component 104, the transmission component 104 is reset by the spring component 105. The hexagonal insert at the rear end of the transmission component 104 disengages from the hexagonal groove of the locking bolt 102. Even if the transmission component 104 is accidentally touched, it will not perform transmission adjustment on the locking bolt 102, thus preventing accidental contact of the locking bolt 102 that would allow the adjustment lever 201 to be operated.

[0032] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
