Description

Technical Field

[0001] The invention relates to the technical field of special gas cabinets, and in particular to a double-cylinder special gas cabinet. Background Art

[0002] The double-cylinder special gas cabinet is an industrial equipment used for the safe storage and supply of special gases. It mainly serves the fields with extremely high requirements for gas purity, stability and safety. Its core design adopts a "primary + backup" double-cylinder configuration, combined with an automatic switching system to ensure the continuity of gas supply.

[0003] The operation process of replacing cylinders in traditional dual-cylinder special gas cabinets is relatively complicated. Specifically, the operator must first close the valve and the bleed valve on the cylinder, and then remove the hose connected to the cylinder. To ensure that no gas remains in the pipeline system, the gas in the pipeline must be completely emptied through the exhaust valve. After completing this series of steps, the operator can manually remove the cylinder. As for installing a new cylinder, it is necessary to reconnect the hose first, and then open the valve and bleed valve on the cylinder one by one in the established order.

[0004] However, in actual applications, people found that this method of replacing cylinders is not only time-consuming and laborious, especially in the disassembly and assembly of cylinders, but also the large number of valves involved further aggravates the cumbersomeness of the operation process.

[0027] Three slide grooves 119 are provided at the top of the inner wall of the protective shell 2, two U-shaped grooves 120 are provided between the three slide grooves 119, slide rods 123 are movably provided in the three slide grooves 119 and the two U-shaped grooves 120, and the three slide grooves 119 and the two U-shaped grooves 120 are interconnected.

[0028] A slotted plate 122 is provided at the bottom end of the slide rod 123, and a sleeve plate 121 is sleeved on the outer surface of the slotted plate 122. The bottom end of the lever 3 passes through the protective shell 2 and is arranged on the top of the sleeve plate 121. A pointed plate 118 is provided on the side of the rack four 117. The output ends of the air cylinder 1 61 and the air cylinder 2 72 are both provided with L-shaped pointed rods 124, and the slotted plate 122 is movably provided on the pointed plate 118 and the two L-shaped pointed rods 124. When the slide rod 123 enters the slide groove 119, the slotted plate 122 will enter the pointed plate 118 or the L-shaped pointed rod 124.

[0029] When using the device, first, the cylinder body 4 needs to be installed in the cabinet 1. At this time, the lever 3 will be pushed to move on the protective shell 2, and the lever 3 will make the slotted plate 122 enter the pointed plate 118, thereby driving the rack four 117 to move, the rack four 117 drives the gear four 116 to rotate, and the gear four 116 drives the flip shaft 115 to rotate, which will drive the tilting plate 5 to rotate. At this time, the cylinder body 4 can be driven to enter the tilting plate 5, and the arc plate 113 can be pulled to fit the outer surface of the cylinder body 4. At this time, the lever 3 is pushed again, so that the lever 3 drives the sleeve plate 121 on the end surface to move, and the sleeve plate 121 drives the slotted plate 122 to move. At this time, the slide bar 123 will enter the U-shaped groove 120 from the slide groove 119, thereby causing the slotted plate 122 to move away from the pointed plate 118 and enter the L-shaped pointed rod 124 at the connecting pipe 71. However, since the air intake valve 67 and the bottle head valve 8 are not opened, it has no effect. At this time, the slotted plate 122 will enter the L-shaped pointed rod 124 of the air cylinder 1 61, and can drive the L-shaped pointed rod 124 to move, and the air cylinder 1 61 will squeeze the gas into the main hose 62, and the gas in the main hose 62 will enter the three-way plate 63, and enter the branch pipe 2 65 and the branch pipe 1 64 through the three-way plate 63. When entering the branch pipe 1 64, it will enter the inflatable telescopic rod 1 66, and then drive the rack 1 615 to move, and the rack 1 615 drives the gear 1 68 to rotate, and the gear 1 68 drives the internal card The block 613 moves, and the clamping block 613 is clamped on the spline shaft 1 611, so that the intake valve 67 is driven to open. At this time, when it needs to be used manually, it is only necessary to press the spline sleeve 1 69 to drive and the spring 1 610. The inclined surface of the end face of the spline sleeve 1 69 squeezes the inclined surface of the straight groove 612. For this reason, the clamping block 613 will enter the straight groove 612 and synchronously squeeze the spring 2 614. For this reason, the spline sleeve 1 69 can drive the spline shaft 1 611 to rotate. The spline sleeve 1 69 will be reset under the action of the spring 2 614 and the spring 1 610 when it is released. At this time, the gas in the branch pipe 2 65 will enter the inflatable telescopic rod 3 101, and the inflatable telescopic rod 3 101 will drive the rack 3 102 and the inclined rod 103 to move at the same time. The movement of the rack 3 102 will drive the gear 3 107 to rotate, thereby driving the spline shaft 2 106 in the gear 3 107 to rotate. At this time, the inclined rod 103 will squeeze the inclined surface of the spline sleeve 2 108, so that the spline sleeve 2 108 drives the limit rod 104 to enter the bottle head valve 8, and at the same time pulls the tension spring 105 to deform; When the cylinder body 4 needs to be disassembled for replacement, it is necessary to pull the lever 3 in the opposite direction, and the intake valve 67 will be reset, the bottle head valve 8 will also be reset, and the spline sleeve 108 will be reset under the action of the tension spring 105. At this time, the slotted plate 122 will drive the output end of the gas cylinder 72 to move, so that the gas cylinder 72 delivers the gas to the connecting pipe 71, and the inflatable telescopic rod 73 drives the rack 74 to reciprocate, so that the exhaust valve 15 is opened and closed, completing the exhaust of the pipeline system, and finally the cylinder body 4 can be flipped out again through the tilting plate 5.

[0030] Example 2: Please refer to Figure 11-12 The present invention provides a technical solution: a plurality of arc-shaped rubber sheets 12 are arranged on the inner side of the arc plate 113, and the outer surfaces of the upper and lower ends of the arc plate 113 are movably inlaid with balls 13, and the balls 13 are movably arranged on the inner wall of the arc groove plate 112. The arranged rubber sheets 12 have a certain anti-slip effect, which can make the arc plate 113 better fit on the cylinder body 4, and the arrangement of the balls 13 can make the arc plate 113 smoother when being pulled.
