Abstract
Description
Technical Field
[0001] The utility model relates to a gas cylinder interface safety protection device, in particular to a gas cylinder interface safety protection device for a semiconductor toxic and corrosive gas supply system. Background Art
[0002] Semiconductor production requires the use of a variety of toxic and corrosive specialty gases. To ensure a high-volume supply of these gases, high-capacity T-bottles (940L), Y-bottles (470L), and long-tube trailers are commonly used.
[0003] Since T / Y cylinders are too large to be placed in gas cabinets, they are generally placed in gas supply rooms or separate gas stations in general supply system designs. This often results in multiple groups of T / Y cylinders in the gas station being in supply, standby, or waiting to be replaced, and all of them are connected to the gas supply cabinet via special gas pipelines. Based on the above situation, it is particularly important to take safety precautions to ensure that the cylinder interfaces are not accidentally removed when replacing special gas cylinders. If protection is not in place, there may be situations where the cylinder interfaces are accidentally removed when replacing the cylinders, or accidentally bumped during operation, causing dangerous situations such as equipment downtime and trace gas leakage and diffusion, which will pose risks to operators and equipment.
[0004] In the existing technology, the protective devices used on small gas supply equipment GC have some shortcomings, such as insufficient protective surface and short protective stroke, which cannot meet the use requirements of T bottles (940L), Y bottles (470L) and long tube trailers in the special gas large-flow supply system. Utility Model Content
[0005] The utility model provides a gas cylinder interface safety protection device, which aims to overcome the above-mentioned shortcomings of the prior art and prevent the interface from being accidentally disassembled when the gas cylinder is replaced and from being accidentally hit during operation.
[0006] The technical solution of the present utility model is a gas cylinder interface safety protection device, which includes a thin cylinder with a guide rod, a square retaining ring, a gas cylinder and a gas supply pipe. The gas supply pipe is arranged vertically, and the gas cylinder interface of the gas cylinder is facing upward and connected to the bottom end of the gas supply pipe. The thin cylinder with a guide rod is installed on the gas supply pipe with the output end facing downward. The bottom end of the piston rod of the thin cylinder with a guide rod is connected to the top plate, and the top plate is connected to the square retaining ring. The square retaining ring has a square protective surface. When the thin cylinder with a guide rod is extended, the square retaining ring blocks the gas cylinder interface. When the thin cylinder with a guide rod is retracted, the square retaining ring is above the gas cylinder interface. During operation, the thin cylinder with a guide rod drives the square retaining ring to perform reciprocating linear motion with the piston rod. When the gas cylinder needs to be replaced, the square retaining ring is retracted upward, leaving space for disassembly of the gas cylinder interface. When the gas is supplied normally, the square retaining ring is extended to block the position of the gas cylinder interface. At this time, there is no operating space at the gas cylinder interface. This prevents the cylinder interface from being accidentally disassembled when the gas cylinder is replaced and from being accidentally bumped during operation.
[0007] Preferably, the thin cylinder with a guide rod is mounted on the air supply pipe via a fixing clamp, thereby achieving a simple installation of the thin cylinder with a guide rod.
[0008] Preferably, the top plate is detachably connected to the square retaining ring via screws, thereby achieving the replaceability of the square retaining ring.
[0009] Preferably, the square protection surface of the square retaining ring is higher than the height of the gas cylinder interface to ensure protection effect.
[0010] The advantages of this utility model are: reasonable structural design, which can prevent the cylinder interface from being accidentally disassembled when the gas cylinder is replaced and accidentally bumped during operation, effectively preventing equipment downtime, trace gas leakage and diffusion, etc., and improving the safety of operators and equipment operation. Specifically, the retractable square retaining ring plays a protective and isolating role at the cylinder interface in 360° directions. When the gas cylinder needs to be replaced, the retaining ring can be retracted to reserve space for disassembly of the cylinder interface; when the gas is supplied normally, the retaining ring blocks the position of the cylinder interface, and there is no operating space at the cylinder interface. It can effectively improve the safety and reliability of the entire gas supply system during bottle replacement operations and operation. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural diagram of the gas cylinder interface safety protection device of the utility model.
[0012] Figure 2 yes Figure 1 side view.
[0013] In the figure, 1 is a thin cylinder with a guide rod, 2 is a piston rod, 3 is a top plate, 4 is a square retaining ring, 5 is a gas cylinder, 51 is a gas cylinder interface, 6 is a gas supply pipe, and 7 is a fixed clamp. DETAILED DESCRIPTION
[0014] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.
[0015] like Figure 1 、 2 As shown, a gas cylinder interface safety protection device comprises a thin gas cylinder 1 with a guide rod, a square retaining ring 4, a gas cylinder 5 and a gas supply pipe 6. The gas supply pipe 6 is vertically arranged, and the gas cylinder interface 51 of the gas cylinder 5 is upwardly connected to the bottom end of the gas supply pipe 6. The thin gas cylinder 1 with a guide rod is installed on the gas supply pipe 6 through a fixing clamp 7 with the output end downward. The bottom end of the piston rod 2 of the thin gas cylinder 1 with a guide rod is connected to the top plate 3, and the top plate 3 is detachably connected to the square retaining ring 4 by screws. The square retaining ring 4 has a square protective surface. When the thin gas cylinder 1 with a guide rod is extended, the square retaining ring 4 blocks the gas cylinder interface 51. When the thin gas cylinder 1 with a guide rod is retracted, the square retaining ring 4 is above the gas cylinder interface 51.
[0016] According to the above structure, when working, the thin cylinder 1 with guide rod drives the square retaining ring 4 to perform reciprocating linear motion with the piston rod 2. The square protection surface height of the square retaining ring 4 should be greater than the height of the gas cylinder interface 51 to be protected, and a certain gap should be reserved between them.
[0017] When the gas cylinder 5 needs to be replaced, the square retaining ring 4 can preferably be linked with the gas cabinet bottle replacement program, and the square retaining ring 4 is retracted upward to reserve space for disassembly of the gas cylinder interface 51.
[0018] When the gas supply is normal, the square retaining ring 4 extends to block the position of the gas cylinder interface 51 and can be interlocked with the gas cabinet program. At this time, there is no operating space at the gas cylinder interface 51. The square retaining ring 4 surrounds and protects the gas cylinder interface 51, providing a 360-degree protection and isolation effect on the gas cylinder interface.
[0019] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
