A pressure vessel with a double cover

Abstract

The invention discloses a double-cover pressing type pressure vessel. The double-cover pressing type pressure vessel comprises a tank body, a tank cover mounted on the tank body, a height-adjustable movable bracket and a pressing device mounted on the movable bracket, wherein an upper ring mounting plate and a lower ring mounting plate are respectively arranged at a junction between the tank cover and the tank body; a hydraulic opening is formed in the tank cover; a detachable hydraulic cover is mounted at the hydraulic opening; a sealing cover body in the middle of the hydraulic cover is divided into two door covers which are articulated with the upper part of the edge of the hydraulic cover. According to the double-cover pressing type pressure vessel, the connection manner between the tank cover and the tank body is a pressing manner; a ring pressing plate is mounted on a hydraulic driving device on the movable bracket via a transverse rod and a vertical rod; the hydraulic driving device is used for driving the ring pressing plate to press the upper ring mounting plate down, so that the upper ring mounting plate can be tightly pressed on the lower ring mounting plate; the double-cover pressing type pressure vessel is extremely convenient to mount.

Description

technical field [0001] The invention relates to a pressure device, in particular to a pressure vessel with double covers. 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. The liquid (gas) is discharged, and the hydraulic port is closed by the hydraulic cover. When using the hydraulic port, the hydraulic cover needs to be opened as a whole; and when necessary, the tank body needs to be opened as a whole, and a flange is usually used between the tank cover and the tank body. The fixed connection of the plate is usually installed by bolts or hinges. When the tank cover needs to be opened, the bolts and hinges need to be removed. It is very troublesome to open and cover; and the usual flange seal installation only takes two The flange plate is fixed and installed by bolts, and its sealing effect is not good. ...

[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. The liquid (gas) is discharged, and the hydraulic port is closed by the hydraulic cover. When using the hydraulic port, the hydraulic cover needs to be opened as a whole; and when necessary, the tank body needs to be opened as a whole, and a flange is usually used between the tank cover and the tank body. The fixed connection of the plate is usually installed by bolts or hinges. When the tank cover needs to be opened, the bolts and hinges need to be removed. It is very troublesome to open and cover; and the usual flange seal installation only takes two The flange plate is fixed and installed by bolts, and its sealing effect is not good. Not only is it inconvenient to install, disassemble and open, but also the fastening is not strong; therefore, it is not very convenient to open the hydraulic cover and tank body of traditional pressure vessels.
