Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a pipeline installation connection structure of a gas purification cabinet. Background Art

[0002] Gas purification technology is to obtain high-purity hydrogen from various industrial gas raw gases through catalytic deoxidation, adsorption drying and filtration dust removal. It requires the use of a gas purification cabinet. After the raw gas is purified, the gas needs to be transported.

[0003] When traditional gas purification equipment is in use, when connecting the pipeline to the gas purification equipment, the pipeline is often connected through a flange. However, when installing the flange, multiple bolts need to be screwed, which is relatively laborious. In addition, the sealing of the flange relies on squeezing the gasket. During long-term use, once the gasket ages, the sealing effect of the gasket will decrease, thereby affecting the normal gas transmission of the pipeline. Utility Model Content

[0009] As a preferred technical solution of the utility model: a battery pack is installed on the outer wall of the support plate, and the battery pack is electrically connected to the sound and light alarm and the trigger switch respectively.

[0021] See also Figure 1-Figure 5 A pipeline installation and connection structure of a gas purification cabinet includes an equipment body 1, a connecting pipe 2 is installed on the outer wall of the equipment body 1, a transmission pipe 3 is installed on the bottom of the connecting pipe 2, a support plate 4 is fixedly installed on the outer wall of the equipment body 1, a sound and light alarm 5 is installed on the top of the support plate 4, the outer wall of the connecting pipe 2 is movably sleeved with a liquid connecting tube 6, a No. 1 fixing ring 7 is installed on the outer wall of the connecting tube 6, a No. 2 fixing ring 8 is rotatably connected to the outer wall of the No. 1 fixing ring 7, a fixing bolt 9 is fixedly installed on the outer wall of the No. 2 fixing ring 8, a fixing nut 10 is threadedly connected to the outer wall of the fixing bolt 9, a fixing plate 11 is fixedly installed on the outer wall of the No. 2 fixing ring 8, a rotating plate 12 is rotatably connected to the outer wall of the fixing plate 11, and a trigger switch 13 is fixedly installed on the outer wall of the No. 1 fixing ring 7.

[0022] The connecting tube 2 and the transmission tube 3 are connected by a connecting tube 6 provided between the outer walls of the connecting tube 2 and the transmission tube 3, so that the gas in the inner cavity of the connecting tube 2 can smoothly enter the inner cavity of the transmission tube 3, and the connecting tube 6 and the connecting tube 2 and the transmission tube 3 are sealed by the No. 1 fixing ring 7 and the No. 2 fixing ring 8 on the outer wall of the connecting tube 6.

[0023] In a preferred embodiment, the inner cavity of the connecting tube 6 is divided into two layers, and the outer wall of the inner layer is in close contact with the inner wall of the connecting tube 2 , and the inner wall of the outer layer is in close contact with the outer wall of the connecting tube 2 .

[0024] By setting the inner cavity of the connecting tube 6 to be two layers, the gas in the inner cavity of the connecting tube 2 can be better blocked from escaping outward under the action of the two layers of partitions in the inner cavity of the connecting tube 6, thereby better realizing the connection between the connecting tube 2 and the transmission tube 3, so that the gas in the inner cavity of the connecting tube 2 can smoothly enter the inner cavity of the transmission tube 3.

[0025] In a preferred embodiment, the inner wall shapes of the second fixing ring 8 and the first fixing ring 7 match the outer wall shapes of the connecting tube 6 and the connecting pipe 2, and rubber sealing pads are installed on the inner walls of the second fixing ring 8 and the first fixing ring 7.

[0026] By installing the No. 1 fixing ring 7 and the No. 2 fixing ring 8 on the outer walls of the connecting tube 6 and the connecting tube 2, the connection between the connecting tube 6 and the connecting tube 2 is achieved under the action of the No. 1 fixing ring 7 and the No. 2 fixing ring 8, thereby achieving the sealing between the connecting tube 6 and the connecting tube 2, thereby better achieving the connection and sealing of the connecting tube 2 and the transmission tube 3 under the action of the connecting tube 6.

[0027] In a preferred embodiment, the outer wall of the rotating plate 12 is L-shaped, and the outer wall of the rotating plate 12 corresponds to the position of the trigger switch 13 .

[0028] By rotating the rotating plate 12 connected to the outer wall of the fixing plate 11, when the No. 1 fixing ring 7 and the No. 2 fixing ring 8 are installed on the outer wall of the connecting tube 6, the rotating plate 12 is rotated so that the outer wall of the rotating plate 12 corresponds to the outer wall of the trigger switch 13. During the use of the No. 1 fixing ring 7 and the No. 2 fixing ring 8, once the No. 1 fixing ring 7 and the No. 2 fixing ring 8 expand, the rotating plate 12 will contact the trigger switch 13 as the No. 1 fixing ring 7 and the No. 2 fixing ring 8 expand, thereby triggering the trigger switch 13.

[0029] In a preferred embodiment: a battery pack is installed on the outer wall of the support plate 4, and the battery pack is electrically connected to the sound and light alarm 5 and the trigger switch 13 respectively.

[0030] By installing a battery pack on the outer wall of the support plate 4, power is supplied to the sound and light alarm 5 under the action of the battery pack. Once the No. 1 fixing ring 7 and the No. 2 fixing ring 8 directly expand, the distance between the No. 1 fixing ring 7 and the No. 2 fixing ring 8 will increase, so that the outer wall of the rotating plate 12 triggers the trigger switch 13. At this time, the sound and light alarm 5 can be energized, thereby prompting the staff to have a gap between the No. 1 fixing ring 7 and the No. 2 fixing ring 8 under the action of the sound and light alarm 5.

[0031] In a preferred embodiment, the outer wall of the transmission tube 3 passes through the inner cavity of the support plate 4 to be connected to the connecting tube 2 , and the inner cavity of the connecting tube 2 is communicated with the inner cavity of the device body 1 .

[0032] By means of the connecting tube 2 arranged on the outer wall of the equipment body 1, the gas coming out of the inner cavity of the equipment body 1 is guided under the action of the connecting tube 2, and enters the inner cavity of the transmission tube 3 under the action of the connecting tube 6, and under the action of the support plate 4 arranged on the outer wall of the equipment body 1, the support plate 4 plays a certain fixing role on the transmission tube 3.

[0033] Working principle: During the use of the above-mentioned equipment, when installing the equipment, the connecting pipe 2 and the transmission pipe 3 are connected, the outer wall of the connecting pipe 2 is inserted into the inner cavity of the connecting tube 6, and the outer wall of the transmission pipe 3 is inserted into the inner cavity of the connecting tube 6. At this time, the No. 1 fixing ring 7 and the No. 2 fixing ring 8 are rotated so that the outer walls of the No. 1 fixing ring 7 and the No. 2 fixing ring 8 can be combined with the outer walls of the connecting tube 6 and the connecting pipe 2, so that the connecting tube 6 and the connecting pipe 2 and the transmission pipe 3 are fixed under the action of the No. 1 fixing ring 7 and the No. 2 fixing ring 8, and the fixing nut 10 is rotated. , the No. 1 fixing ring 7 and the No. 2 fixing ring 8 are fixed under the action of the fixing nut 10, and the rotating plate 12 is rotated after the No. 1 fixing ring 7 and the No. 2 fixing ring 8 are fixed, so that the outer wall of the rotating plate 12 overlaps the outer wall of the trigger switch 13. Once the No. 1 fixing ring 7 and the No. 2 fixing ring 8 expand during use, the rotating plate 12 will trigger the trigger switch 13 in the first time, thereby starting the sound and light alarm 5 under the action of the trigger switch 13, and the sound and light alarm 5 prompts the user that the installation of the No. 1 fixing ring 7 and the No. 2 fixing ring 8 is loose.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
