An adjustable double-cover double-compression pressure vessel

Abstract

The invention discloses an adjustable double cover body double-pressing-type pressure vessel. The adjustable double cover body double-pressing-type pressure vessel comprises a tank body, a tank cover, a movable bracket adjustable in height and an adjustable type pressing device, wherein the tank cover is installed on the tank body, and the adjustable type pressing device is installed on the movable bracket. An upper circular ring installation plate and a lower circular ring installation plate are arranged at the joint of the tank cover and the tank body, and the tank cover is further provided with a hydraulic opening. The hydraulic opening is provided with a detachable hydraulic cover. According to the adjustable double cover body double-pressing-type pressure vessel, the closing mode of two door covers is also of a pressing type, door slots between the two door covers can be all pressed and blocked through long-strip pressing plates installed on a second hydraulic cylinder, and in this way, opening and closing of the door covers are very convenient; moreover, each long-strip pressing plate is provided with a sealing rubber pad, after the door slots are pressed through the sealing rubber pads, the sealing performance can be improved, and pressure leakage is prevented; and in addition, clamping blocks arranged on the long-strip pressing plates are pressed into clamping grooves in the door covers during pressing, not only can positioning be conducted, but also the stability can be reinforced, the impact resistance is improved, and the situation that the door covers are opened due to excessive pressure or accidental causes is prevented.

Description

technical field [0001] The invention relates to a pressure device, in particular to an adjustable double-cover double-compression pressure vessel. Background technique [0002] The pressure vessel is usually used to contain gas or liquid, and must be able to withstand relatively high pressure. The pressure vessel is usually composed of a tank body and a tank cover. For the liquid (gas outlet), because it must bear a large pressure, the tank cover and the tank body are usually fixedly connected by a flange, which is usually installed by bolts or hinges. When the tank cover needs to be opened, it is necessary to It is very troublesome to disassemble the bolts and disassemble the hinge device, and it is very troublesome to open and cover; and the usual flange sealing installation is only two flanges fixed by bolts, the sealing effect is not good, not only inconvenient to install, disassemble and open, but also tight Not strong.
