A kind of high-pressure tank and its manufacturing method

Abstract

The invention belongs to the technical field of high-pressure tanks, and discloses a high-pressure tank and a manufacturing method thereof. The high-pressure tank includes: an end cover assembly, including an end cover body and an end cover flange; a tank body, including a tank body and two tank flanges respectively arranged at both ends of the tank body, and the tank flange and the end The cover flange is connected; multiple bolts are installed on the tank body flange and the end cover flange for connecting the end cover assembly and the tank body; the fiber reinforcement layer can connect multiple bolts. The manufacturing method specifically includes: preparing a fiber reinforcement layer, winding the fibers on multiple bolts, increasing the pressure bearing strength of the tank flange or the end cover flange at the bolts, overcoming the defect of poor strength at this position, and then The pressure bearing strength of the high pressure tank is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-pressure tanks, in particular to a high-pressure tank and a manufacturing method thereof. Background technique [0002] Usually, in order to withstand the underwater high-pressure working environment, the general unmanned underwater workboat needs to place each working component in a sealed shell or a sealed tank with a certain pressure bearing capacity, wherein the sealed shell or sealed tank can be Collectively referred to as high pressure tanks. [0003] In order to facilitate the loading of working components, the end cover of the high-pressure tank and the tank body are sealed and connected by flanges. However, at the position of the flange locking bolt, its pressure-bearing strength is poor, so this position is basically a short plate of the pressure-bearing structure. In addition, because high-pressure tanks are generally made of steel, in order to ensure a good pressure-bearing effect of hi...

Problems solved by technology

However, at the position of the flange locking bolt, its pressure-bearing strength is poor, so this position is basically a short plate of the pressure-bearing structure

In addition, because high-pressure tanks are generally made of steel, in order to ensure a good pressure-bearing effect of high-pressure tanks, high-pressure tanks are relatively thick, which makes the weight of high-pressure tanks relatively heavy, which is not conducive to meeting the needs of lightweight
