Embodiment

[0030] Such as Figure 1-6 As shown, the horizontal quick-opening door structure of the kettle is adopted. The kettle body includes an oval head 8, a cylinder body 5, and a kettle body flange. The lower part of the kettle body is provided with three supports 3, and the three supports 3 are installed horizontally with three saddles. One end of the kettle body is provided with a movable kettle cover 2, and the movable kettle cover 2 is connected to the kettle body through the direct bite mode of the kettle cover flange and the kettle body flange, and the kettle cover flange and the kettle body flange are sealed with a sealing ring 9 under pressure The sealing structure, the material of the sealing ring 9 adopts nitrile rubber. The movable kettle cover 2 includes a spherical head and a kettle cover flange. The opening direction of the movable kettle cover 2 is circumferential rotation and side rotation. The movable kettle cover 2 is equipped with a kettle cover opening system pow...

Abstract

The invention relates to a quick-opening gate type external pressure air-tightness test tank. According to the quick-opening gate type external pressure air-tightness test tank, a kettle type horizontal quick-opening gate structure is used, a supporting base is arranged on the lower portion of a kettle body, a moving kettle cover is arranged at one end of the kettle body, a kettle cover opening system with a hydraulic motor serving as the motive power is arranged on the moving kettle cover, and a kettle body working platform and a transfer railway are installed inside the kettle body. By the aid of the quick-opening gate structure, pressurization, pressure maintaining and pressure reducing of the kettle body and closing and opening of the kettle cover can be conducted frequently, and the quick-opening gate structure is an ideal device through which test pieces enter the kettle body repetitively. The hydraulic motor is used for substituting for an electrical device, a safety interlocking device and the like, so that the air-tightness test tank can be used in strict operating environments in which frequent opening is conducted and fire lighting is not allowed, the device operating space is reduced, and the economical efficiency and the safety of the device are improved. By the aid of the quick-opening gate type external pressure air-tightness test tank, air-tightness test tanks are used widely.

Description

technical field [0001] The invention relates to an external pressure airtight test equipment, in particular to a quick-opening type external pressure airtight test tank. Background technique [0002] The equipment with quick-opening structure can realize the frequent pressurization, pressure maintenance, decompression of the tank body and the closing and opening process of the kettle lid. It is an ideal equipment for realizing the repeated entry of the test piece into the tank body. If this large quick-opening door structure is used for external pressure airtight test tanks, it will broaden the design field of the pressure vessel industry, but the main design problems in the existing design are as follows: [0003] (1) Anti-static design, no electrical equipment is allowed on the equipment; [0004] (2) The strength requirements of the kettle cover and the kettle body flange; [0005] (3) Technical requirements for the design, manufacture and installation of the working pl...
