Embodiment 1

[0021] Such as figure 1 As shown, a welded insulated gas cylinder includes a cylinder body, a valve seat, a safety valve 18, a rupture disc, a pressure gauge 6, a liquid level gauge 4 and a connecting pipe 19, and the cylinder body is composed of an inner tank 1 and an outer shell 3 , a vacuum interlayer 20 is formed between the inner tank 1 and the outer shell 3, and a heat insulating layer 21 is provided in the vacuum interlayer 20; an upper liquid inlet pipe 2 and an exhaust pipe 12 are inserted into the upper part of the bottle body, and the exhaust pipe The connecting pipe 19 between the pipe 12 and the exhaust port is provided with an exhaust valve 14; the upper part of the bottle body is also inserted with a pressurizing pipe 17 and a boost regulating pipe 15, and the two are respectively provided with a boosting valve. 5 and boost regulator valve 16 and communicated; the welded heat insulating gas cylinder is also provided with a support system and an internal evaporat...

Embodiment 2

[0023] A welded heat-insulating gas cylinder, the same as in Example 1, the difference is that the heat-insulating layer 21 is set as a two-layer heat-insulating wrapping layer structure, and holes are punched on each layer; the radiation-proof layer adopts a 6 μm aluminum foil structure , and the getter layer attached to the outer wall 13 of the inner tank in the inner evaporator adopts a low-temperature getter layer structure with an activation temperature of 15° C., that is, a propylene glycol layer structure.

Embodiment 3

[0025] A welded heat-insulating gas cylinder is the same as that in Example 1, except that the heat-insulating layer 2 is perforated with holes every two layers, and the radiation-proof layer adopts a 10 μm aluminum foil structure.

[0026]In this way, when in use, a welded insulating gas cylinder of the present invention adopts a high-vacuum multilayer insulation method, and its aluminum foil has been degreased and dewaxed before use; during the wrapping process of the multilayer insulation body, its Bandage according to the designed layer density, by controlling the density of the layer, prevent the increase of air resistance between the layers; at the same time, avoid the disconnection of the reflective layer, so that the radiation window is left to cause a short circuit, that is, the reflective layer is connected; each wrapping After a certain number of layers, holes should be properly drilled, or holes should be drilled in advance on each layer of insulation material to fa...

Abstract

The invention relates to a pressure container with heat insulation measures, in particular to a welded adiabatic gas cylinder which comprises a cylinder body, a valve base, a safety valve, a rupture disk, a pressure gauge, a liquidometer and a connection pipe. The cylinder body consists of an inner tank and a housing; a vacuum interlayer is formed between the inner tank and the housing; an insulating layer is arranged in the vacuum interlayer; a supporting system and an inner evaporator are also arranged on the welded adiabatic gas cylinder; the supporting system is arranged in the vacuum interlayer and connected with the inner tank; the insulating layer is a structure of more than two layers of insulated packing layers, and the inner evaporator is arranged in the vacuum interlayer and provided with a degasser layer attached on the inner tank or attached on the housing. The welded adiabatic gas cylinder has the advantages of low heat leakage, good low-temperature insulating effect, excellent supporting strength, convenience for use, high loading rate, security and reliability, high purity of stored gas, high vacuum degree, long vacuum service life and the like and is mainly applied to low-temperature liquid such as liquid oxygen, liquid nitrogen and liquid argon.

Description

technical field [0001] The invention belongs to the technical field of pressure vessels, and in particular relates to a pressure vessel with heat insulation measures. Background technique [0002] With the popularization and application of cryogenic technology, cryogenic liquid has been gradually applied to industrial production and civil life from the earliest high-end technology application, and cryogenic insulating gas cylinders are used as equipment for storing liquid oxygen, liquid nitrogen, liquid argon and other low-temperature liquefied gases , compared with traditional Dewar bottles and high-pressure steel gas cylinders, it has the characteristics of safety, reliability, convenient use, high loading rate and refillable. At present, most of the cryogenic insulating gas cylinders produced industrially have the following problems: (1) Most of them adopt a double-cylinder structure with high-vacuum multi-layer insulation, the inner cylinder and the outer cylinder are ma...
