Water jacket and water pressure test device applying same

Abstract

The invention provides a water jacket which comprises a water jacket cover and a water jacket body that are mutually matched, wherein the water jacket is sealed by adopting a C-shaped gland cover and the water jacket body, and the lower side of the water jacket cover is provided with an elastic cylinder opening gasket used for sealing a gas cylinder opening and the water jacket. The invention has the advantages that the tightness is of the water jacket is good, the tightness of the water jacket and the gas cylinder opening is also good, a thread at the gas cylinder opening after the test is finished is not easy to damage; and compared with the prior art, a water pressure test device applying the water jacket of the invention has simple structure, stable property, high production efficiency and great energy consumption reduction.

Description

technical field [0001] The invention relates to a hydraulic test system of an external measurement method in the field of hydraulic test of gas cylinders, in particular to a hydraulic test device using a new type of water jacket. Background technique [0002] With the development of the economy and the popularization and application of modern technology, the consumption of compressed gases such as natural gas, hydrogen, and helium has increased sharply, and gas cylinders have become the preferred containers for such compressed gases. In order to improve the volume-to-weight ratio and pressure-bearing capacity of gas cylinders, the technical solution generally adopted in this field is to use high-quality high-pressure seamless steel pipes as much as possible, process them into inner tanks by screwing and compressing the neck at the end, and then select high-strength fiber The reinforced resin matrix is ​​wound and cured on the outer wall of the inner tank to form a layer of c...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing gas cylinder hydrostatic tests use complex and cumbersome hydrostatic test system devices, which have defects such as unstable performance of the hydrostatic test system, low production efficiency, and large energy consumption.

After the high-pressure pump is turned on, it is always in the working state, and it is not turned off until the test is completed. It is easy to be damaged after long-term work, and a lot of energy is wasted; the sealing method of the water jacket is mechanically compressed and sealed by the sealing cover. The air bubbles are not easy to discharge, which seriously affects the accuracy and stability of the test data, and qualified products are easily detected as waste products; the sealing method of the gas cylinder mouth is a raw material belt seal, and because the bottle mouth thread is repeatedly loaded and unloaded, the bottle mouth thread is mixed with a lot Residual raw material tape, the thread cleaning rate of the bottle mouth is 100%, and the thread is easily damaged, which affects the quality of the product. At the same time, the test water carries a large amount of residual raw material tape in the water circulation pipeline, which is easy to block the valve and damage the recycled water quality. and many more
