Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, a split ring type quick-opening device for the sealing end cap of a container is set at the operating hole of the container, and its structure specifically includes a cylinder flange 12, a sealing ring 11, a flat cover 10, multiple sets of guide mechanisms and multiple sets of split rings. Claw mechanism;

[0025] The cylinder flange 12 is fixed at the operating hole of the container, and can be directly welded to one end of the cylinder, or a connecting piece can be installed on the container to weld the cylinder flange 12. The cylinder flange 12 includes an inner hole with a step; the flat cover 10 is arranged at the step of the inner hole, and a sealing ring 11 is provided between the flange 12 and the flat cover 10 . The sealing ring 11 can be arranged on the end surface.

[0026] Specifically in this example, the flat cover 10 is a variable diameter structure, and the shoulder of the variable diameter is in contact with t...

Embodiment 2

[0037] A natural gas filter, which adopts the above-mentioned container sealing end cap split ring type quick-opening device, and the opening on one side of the natural gas filter cylinder 13 is the operation hole.

[0038] Owing to adopting above-mentioned technical scheme, the present invention has following advantage and effect:

[0039] 1. It can effectively and safely realize the opening and closing action of the sealing end cap of the container, such as quick replacement of the filter core of the natural gas filter, with low labor intensity.

[0040] 2. The structure is compact and simple, and the space occupied is small.

[0041] 3. Changing the specific structural size can adapt to different work flow requirements.

Abstract

The invention discloses a subdivision ring type fast opening device for a container sealing end cover. The subdivision ring type fast opening device is arranged on an operating hole (13) of a container and comprises a barrel body flange (12), a sealing ring (11), a flat cover (10), a plurality of guiding mechanisms and a plurality of subdivision claw mechanisms. The barrel body flange (12) is fixed to the operating hole (13) of the container and comprises an inner hole with a step. The flat cover (10) is arranged on the step of the inner hole. A sealing ring (11) is arranged between the flange (12) and the flat cover (10). The flat cover (10) is controlled by the subdivision claw mechanisms so that the flat cover (10) and the flange (12) can be pressed, sealed, opened and separated. The subdivision ring type fast opening device is simple and compact in structure, reasonable in stress, reliable in operation, not prone to being stuck and good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of mechanical structures; in particular, it relates to a split-ring type quick-opening device for a container sealing end cap. Background technique [0002] Some containers in the technical field, especially the pressure vessels in the chemical industry, generally need to be designed with sealing end caps and operating holes, observation holes, etc. For example, a natural gas filter needs to be equipped with an operation hole for cleaning or replacing the filter element, and the operation hole needs to be opened and closed frequently, which requires the use of a quick-opening structure. Currently, there are structures such as hoop type, tooth mesh type, and split ring type. , is not only complicated, but also the overall structure is not compact enough, the force is unreasonable, and it is prone to jamming and poor sealing. Contents of the invention [0003] The object of the present invention is to provi...
