Abstract

The utility model discloses a disposable gas storage cylinder body. A gas storage cylinder is composed of an upper gland (1), a pipe (3) and a lower gland (5), wherein the upper gland (1) is connected with the pipe (3) through a first soldered joint (2), the pipe (3) is connected with the lower gland (5) through a second soldered joint (4), the end part of the upper gland (1) is of a necking shape, and the end part of the lower gland (5) is a necking shape. The gas storage cylinder body in the technical scheme disclosed by the utility model is composed of two shallow glands and a section of pipe, under the condition of unchanging the total size, the material use rate is improved. Since the shallow gland replaces the deep tensile gland, the process difficulty of gland machining is lowered, the requirement on material and device is reduced, and the defective index of the parts is lowered.

Description

Disposable gas cylinder

technical field

The utility model relates to the technical field of disposable small gas cylinders, in particular to a gas storage cylinder body of a 30-ounce disposable gas cylinder. the

Background technique

The 30-ounce disposable gas cylinder is a large number of gas cylinders used abroad. The product is composed of bottle body, filling and discharging valve and other parts. The bottle body is composed of upper and lower bottle shells, valve seats, bases and other parts through brazing joints. The gas in this gas cylinder is stored in a cylinder body composed of two long straight cylinder heads. the

The processing process of the two longer straight heads is as follows: punch out the disc with a flat plate; then stretch the disc into a longer straight head structure; then cut off the uneven part of the cup mouth caused by the stretching; The mouth is assembled with the upper head and the gas storage cylinder body is formed by brazing joints. ``

The main problem of the disposable gas storage cylinder with this structure is that the raw material of the long straight cylinder head is punched out of a disc with a flat plate, and then the circle is stretched into a long straight cylinder head. Therefore, the processing of this part will produce more waste materials, and the material utilization rate is low. The second is due to stretching the wafer into a longer straight head. It is a deep drawing process. This process is a process that has high requirements for materials and equipment, and the scrap rate is relatively high.

Contents of the invention

In order to solve the technical problems of easy generation of waste materials and low utilization rate of materials in the processing process of the gas storage cylinder in the prior art, the utility model provides a new disposable gas storage cylinder. the

A disposable gas storage bottle, the gas storage bottle is composed of an upper head 1, a pipe 3 and a lower head 5; the upper head 1 and the pipe 3 are connected by a first brazing joint 2; the pipe 3 and the lower The head 5 is connected by a second solder joint 4 . the

The end of the upper head 1 is in the shape of a constriction, and the end of the lower head 5 is in the shape of a constriction. The upper sealing head 1 and the lower sealing head 5 are shallow sealing heads. the

In the technical solution of the utility model, the gas storage bottle body is composed of two shallow heads and a section of pipe, and the material utilization rate is improved under the condition that the overall size remains unchanged. The structure uses a shallow head instead of a deep-drawn head, thus reducing the technical difficulty of head processing; reducing the requirements for materials and equipment; and reducing the scrap rate of parts at the same time. the
