High-pressure tank and manufacturing method thereof

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 comprises end cover components, a tank body, a plurality of bolts and a fiber reinforcing layer, wherein each end cover component comprises an end cover body and an end cover flange; the tank body comprises two tank body flanges respectively arranged at two ends of the tank body, and each tank body flange is connected with the corresponding end cover flange; the bolts penetrate through the tank body flanges and the end cover flanges,and are used for connecting the end cover components with the tank body; and the fiber reinforcing layer is capable of connecting the bolts. The manufacturing method concretely comprises the following steps of preparing the fiber reinforcing layer, and winding fibers onto the bolts. The bearing strength of the tank body flanges or the end cover flanges at positions of the bolts is increased, andthe intensity difference defect of the positions of the tank body flanges or the end cover flanges is overcome, further guaranteeing the bearing strength of the high-pressure tank.

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
