A double cover pressure vessel

Abstract

The invention discloses a pressure vessel with double cover bodies. The pressure vessel comprises a tank body and a tank cover arranged on the tank body, wherein an upper mounting plate and a lower mounting plate are separately arranged at connecting parts between the tank body and the tank cover and are fastened together through arranged hoop bands; hydraulic openings are formed in the tank cover; and a detachable hydraulic cover is arranged on each hydraulic opening. According to the pressure vessel disclosed by the invention, the tank cover and the tank body are arranged by clamping through the hoop bands; hoop grooves of the hoop bands can wrap and clamp the upper and lower mounting plates therein; one end parts of the hoop bands only need to be connected, so that one ends of the hoop bands only need to be opened when the tank body is opened; transverse grooves and transverse luges are separately arranged on the side walls of the upper and lower mounting plates and in the hoop grooves; and the transverse grooves and the transverse luges are matched for use, and are mutually pressed, so that the fastness of the tank cover and the tank body is improved, and the sealing property is also enhanced.

Description

technical field [0001] The invention relates to a pressure device, in particular to a double-cover pressure vessel. Background technique [0002] Usually, the tank body and the tank cover of the pressure vessel are fixedly connected by a flange, and its disassembly and installation are very troublesome; and if the flange seal is installed through the flange, once the flange seal is damaged, it will cause serious pressure loss in the tank, resulting in major safety hazards. Accidents, the installation of the flange is not only troublesome to disassemble, but also has no good sealing measures; usually the hydraulic port (including the liquid inlet and the liquid outlet) on the tank cover is sealed through the hydraulic cover, and the usual installation method is through thread rotation If the installation and fastening bolts are fastened, the hydraulic cover needs to be disassembled as a whole when using the hydraulic port, which is very troublesome to use.

[0002] Usually, the tank body and the tank cover of the pressure vessel are fixedly connected by a flange, and its disassembly and installation are very troublesome; and if the flange seal is installed through the flange, once the flange seal is damaged, it will cause serious pressure loss in the tank, resulting in major safety hazards. Accidents, the installation of the flange is not only troublesome to disassemble, but also has no good sealing measures; usually the hydraulic port (including the liquid inlet and the liquid outlet) on the tank cover is sealed through the hydraulic cover, and the usual installation method is through thread rotation Installation and fastening bolts are installed tightly. When using the hydraulic port, the hydraulic cover needs to be disassembled as a whole, which is very troublesome to use.
