[0002] In semiconductor production lines, how to ensure that various utility systems (such as ultrapure water, specialty gases, chemicals, and electricity) are stably, safely, and efficiently distributed from the main system to the points of use of various process equipment is the key to maintaining the normal operation of the production line and product quality. This distribution process relies on an infrastructure called the secondary distribution system, which plays a vital role in semiconductor factories. Its design and configuration are directly related to the stability of the production line, the quality of the final product, and the control of production costs. As a core component of the secondary distribution system, the equipment piping area is responsible for accurately transporting various resources to the locations required for production. Specifically, the equipment piping area is mainly composed of piping systems, valves, instruments, and corresponding control systems.

[0003] However, in actual production, the control of valve openings and closings for control valves and instruments on the supply side of equipment pipelines has become a pressing issue. Human error can cause valves to be opened or closed arbitrarily, altering process supply conditions and severely impacting mass production stability and product consistency. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, the present invention provides a locking mechanism for a pipeline valve switch, primarily used for resource control in semiconductor production lines. This mechanism effectively secures the open or closed state of a valve switch 10 in a pipeline 12, effectively preventing manual manipulation of the valve switch 10. This ensures that the valve switch 10 remains in the normal open state during operation and in the normal closed state after the operation, thereby improving the safety of the valve switch 10.

[0024] The structure of the mechanism includes a first fixing plate 1 and a second fixing plate 2 fixed on both sides of the valve switch 10. One end of the first fixing plate 1 and the second fixing plate 2 are connected by a detachable locking plate 3. When installing the first fixing plate 1 and the second fixing plate 2, they can be installed through the mounting plates 7 at the rear ends of the first fixing plate 1 and the second fixing plate 2. They can be fixed to walls, plates and other locations to form a space between the first fixing plate 1 and the second fixing plate 2 for placing the valve switch 10.

[0025] Regarding the position of the locking plate 3, it is located in front of the valve switch 10 and is used to secure the valve switch 10 in its open or closed position. Since the valve switch 10 can operate in two different states, the locking plate 3 is removable for easier user operation. When connected, one end of the locking plate 3 is connected to the first fixing plate 1, while the other end is locked to the second fixing plate 2 via a combination lock 4. In other words, the user needs to enter a password to unlock the combination lock 4, remove the locking plate 3, and then adjust the valve switch 10 to open or close.

[0026] When assembling the locking plate 3 onto the first fixing plate 1 and the second fixing plate 2, the first fixing plate 1 is provided with a hole 101. The end of the locking plate 3 connected to the first fixing plate 1 is provided with a first connecting portion 301 that snaps into the hole 101. The first connecting portion 301 is provided with an arcuate surface, which allows the locking plate to adjust its angle and position. In addition, the second fixing plate 2 is connected to the lock plate 201. The end of the locking plate 3 connected to the second fixing plate 2 is provided with a second connecting portion 302 that fits on the top of the lock plate 201. The second connecting portion 302 and the lock plate 201 both have a lock hole 8 for installing the combination lock 4. After the second connecting portion 302 and the locking plate 201 are pressed together and aligned with the position of the lock hole 8, the user can directly install the combination lock 4 and secure it.

[0027] To facilitate the locking plate 3's ability to position and secure the valve switch 10, a groove 5 is provided on the side of the locking plate 3 near the valve switch 10. This groove 5 extends horizontally and is designed to accommodate the valve switch 10 when it is turned horizontally. Furthermore, two notches 6 are provided on the upper and lower sides of the locking plate 3, communicating with the groove 5. These notches 6 are designed to secure the valve switch 10 when it is turned vertically. For example, if the valve switch 10 is turned horizontally, it is open, and turned vertically, it is closed. To open the valve switch 10, the user simply slides the groove 5 of the locking plate 3 over the outside of the valve switch 10, securing it, and then locking it with the combination lock 4. To close the valve switch 10, the user simply slides the groove of the locking plate 3 over the outside of the valve switch 10. The extended portions of the valve switch 10 at both ends snap into place within the notches 6, and then locking it with the combination lock 4. It should be noted that when the locking plate 3 is installed, the center of the valve switch 10 is located in the groove 5 regardless of whether the valve switch 10 is in the open or closed state. Through the above two operation methods, whether the valve switch 10 is in the open or closed state, it can effectively prevent the valve switch 10 from being manually turned.

[0028] In addition, a sponge block 9 is provided in the groove 5. Since the sponge block 9 has a certain shrinkage and extrudability, when the valve switch 10 is provided in the groove 5, the sponge block 5 will be squeezed. The friction between the sponge block 9 and the valve switch 10 can also prevent the valve switch 10 from moving or rotating.

[0029] Compared with traditional technology, the locking mechanism provided by this technical solution, after the locking plate 3 is put on the outside of the valve switch 10, fixes the position of the valve switch 10 after opening or closing through the groove 5 and the notch 6, protects and limits the position of the valve switch 10, and also uses the combination lock 4 to lock the locking plate 3, thereby improving the safety of use and effectively preventing others from twisting the valve switch 10 to affect the operation.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
