Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a segmented pressure vessel. Background Art

[0002] Standard gas is a term in the gas industry. There are dozens of common types, including carbon monoxide, carbon dioxide, sulfur dioxide, formaldehyde, benzene, etc. The chemical properties of different gases (mainly referring to the chemical reaction mechanism of gas and gas cylinder materials, the most common of which is aluminum alloy) are not the same, and the physical adsorption properties are even more different. In order to ensure the stability of standard gas storage, it is strictly required that the inner wall of the gas cylinder can neither chemically react with the core gas components in the standard gas, nor undergo strong physical adsorption. Due to the particularity of standard gases, the standard gases produced by larger-scale and more well-known standard gas manufacturers at home and abroad are relatively stable and reliable in quality, but the canned high-pressure gas cylinders they use are often larger cylinders with a volume of 40 liters or more. Except for laboratories with large usage, many units will cause great waste in actual use.

[0003] Among them, the authorized patent with publication number CN217382496U (segmented pressure vessel): includes a bottle bottom, a bottle body and a bottle head assembled in segments, the bottle body is a cylinder with two open ends, one end of the bottle body is sealed by the bottle bottom through the first sealing component, and the other end is equipped with the bottle head through the second sealing component, and the bottle head is provided with an outlet for connecting the inside and outside of the pressure vessel. This application avoids the problem of difficult processing of the inner side wall of the container in the prior art by assembling the bottle bottom, bottle body and bottle head in segments. On the basis of the open structure, each component can flexibly select a suitable surface processing technology to effectively avoid problems caused by gas adsorption. Cooperating with the first sealing component and the second sealing component overcomes the problem of reduced strength caused by the split structure. The overall structure is simple and stable, with low production cost, and has extremely high promotion value.

[0004] However, the above technical solution uses a threaded rotation connection between the bottle body, the bottle head and the bottle bottom, which causes the sealing ring arranged between them to be displaced or even damaged during connection, resulting in reduced internal sealing of the split-type pressure vessel, and even leakage when the internal gas is stored, resulting in reduced safety. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a segmented pressure vessel, which can conveniently install the split pressure vessel, ensure the sealing of the pressure vessel, and avoid leakage of gas inside the pressure vessel.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a segmented pressure vessel, comprising a tank body, a can and a tank bottom which can be arranged on the top and bottom ends of the tank body, and a mounting mechanism for sealingly mounting the can and the tank bottom on the tank body, the mounting mechanism comprising a first positioning ring fixedly arranged at the end positions of both ends of the side surface of the tank body, a second positioning ring fixedly arranged at the bottom end of the side surface of the can and the top end of the side surface of the tank bottom and cooperating with the first positioning ring, and two fixing half rings which are semi-annular structures and are connected at one end by a rotating block and at the other end by a fixing assembly, and the inner ring surface of the fixing half ring is provided with a fixing groove which can be sleeved on the first positioning ring and the second positioning ring.

[0007] Preferably, annular sealing grooves are provided on both end surfaces of the tank body, and sealing rings are passed through the sealing grooves.

[0008] Preferably, the groove walls in the fixing groove adjacent to the top and bottom ends of the fixing half ring are both inclined, and the distance between the two inclined surfaces gradually increases from the inside to the outside of the fixing groove.

[0009] Preferably, the fixing assembly includes connecting blocks respectively arranged on the side surfaces of the two fixing half rings away from the rotating block, positioning bolts and auxiliary rings passing through the rotating grooves provided in the end surfaces of the two connecting blocks, and a rotating shaft arranged in the rotating groove for rotating the positioning bolts and the auxiliary rings along the vertical axis, and the fixing screw rod passes through the auxiliary ring and can be threadedly connected to the positioning bolt.

[0010] Preferably, the mounting mechanism further comprises a limiting ring fixedly arranged on the bottom end surface of the can and the top end surface of the can bottom and can be inserted into the clamping grooves formed on the end surfaces at both ends of the can body.

[0011] Preferably, the mounting mechanism further comprises a limiting strip fixedly arranged on the wall of the clamping groove along the axial direction of the tank body, and when the limiting ring is inserted into the clamping groove, the limiting strip is inserted into the limiting groove opened on the side of the limiting ring.

[0012] The beneficial effects of the utility model are as follows: the can and the tank bottom are directly placed on the top and bottom ends of the tank body respectively, and at this time, the two first positioning rings arranged on the two ends of the side of the tank body will fit with the second positioning rings arranged on the can and the tank bottom, and at this time, the two fixed half rings connected by the rotating block are sleeved on the first positioning ring and the second positioning ring through the opened fixing groove, and a sealing ring is arranged between the end of the tank body and the can and the tank bottom, which ensures the sealing between the split pressure vessel, can conveniently install the split pressure vessel, and ensures the sealing of the pressure vessel, avoiding leakage of gas inside the pressure vessel.

[0021] Annular sealing grooves are provided on both end surfaces of the tank body 1, and sealing rings are inserted into the sealing grooves.

[0022] like Figure 3 As shown, the groove walls in the fixing groove 6 adjacent to the top and bottom ends of the fixing half ring 4 are inclined, and the distance between the two inclined surfaces from the inside to the outside of the fixing groove 6 gradually increases. When the two fixing half rings 4 are sleeved on the first positioning ring 12 and the second positioning ring 13 through the fixing groove 6, the upper and lower groove walls of the fixing groove 6 are inclined. At this time, the two inclined surfaces will fit with the side surfaces of the first positioning ring 12 and the second positioning ring 13.
