Problems solved by technology

The whole ring is divided into blocks, so that in theory, the opening and closing process can be completed only by overcoming the weight of the split ring and its frictional resistance. Compared with the overall lock ring structure, the opening and closing force will be reduced, but the existing opening and closing device The complex structure makes the control inconvenient. This application provides a separate opening and closing device

Embodiment 1

[0040] Such as Figure 2~3 As shown, this embodiment provides a separate opening and closing device, which is installed on the ring lock type quick-opening blind plate structure, and the split ring 1 is installed on the high neck flange 9 of the blind plate (set at the inlet and outlet positions of the pressure vessel) Between the flange 9) at the place and the door cover 10, the split ring 1 is connected with the push-pull mechanism through the connecting rod 8, and the push-pull mechanism is subjected to the force of the rotating mechanism, which drives the split ring 1 to move to realize the door opening and closing process.

[0041] Such as Figure 4 As shown, the turntable 3 is provided with a sliding track 4, that is, a thrust groove. In this embodiment, the thrust groove is an arc-shaped thrust groove evenly distributed along the circumference of the turntable 3, and the arc-shaped thrust groove is in the shape of an impeller, that is, the arc-shaped thrust groove and t...

Embodiment 2

[0045] Such as image 3 As shown, the difference from the above-mentioned embodiment 1 is that in this embodiment, the axis of the cantilever shaft 2 coincides with the central axis of the pin 6, so that the force transmission efficiency is higher.

[0046]The application provides a separate opening and closing device, the rotating mechanism and the push-pull mechanism cooperate with each other, corresponding to a split ring, to realize the separate control of the split ring, the structure is simple, easy to control, and convenient to operate. At the same time, a chain mechanism is set between the separate opening and closing units, so that each separate opening and closing unit is opened or closed one by one in order to avoid omission of points.

Abstract

The invention belongs to the technical field of quick-open sealing, and particularly relates to a separated opening and closing device. An existing opening and closing device is complex in structure and then is inconvenient to control. The provided separated opening and closing device comprises a plurality of separated opening and closing units, each separated opening and closing unit comprises arotating mechanism, a push-pull mechanism and a split ring which are sequentially connected from top to bottom, each rotating mechanism comprises a rotating arm shaft, each push-pull mechanism comprises a rotating disc, each rotating disc is arranged on a door cover, the rotating discs are connected with the rotating arm shafts, sliding rails are arranged on the rotating discs, thrust rollers arearranged in the sliding rails, column pins are arranged in the thrust rollers, guide rollers are arranged outside the column pins, connecting rods are fixedly connected to the lower ends of the columnpins, sliding grooves are formed in the door cover, the connecting rods are arranged in the sliding grooves, the split rings are connected with the connecting rods, and the split rings are arranged between a flange and the door cover. Each rotating mechanism and the corresponding push-pull mechanism cooperate with each other to correspond to one split ring, then independent control over the splitrings is achieved, the structure is simple, the control is easy, and the operation is convenient.

Description

technical field [0001] The application belongs to the field of quick-opening sealing technology, and in particular relates to a separate opening and closing device. Background technique [0002] The quick-opening blind plate structure is a mechanical device installed at the end of a pressure vessel or pressure pipeline to realize rapid opening and closing. It is widely used in oil and gas, chemical, aerospace, electric energy and other industrial fields. Compared with the bolt flange structure, the quick-opening blind plate structure opens and closes the door cover more quickly, and is suitable for industrial applications where the door cover needs to be frequently assembled and disassembled. [0003] Because the ring lock structure has the advantages of easy opening and closing of the blind door cover, simple and reasonable load-bearing structure, etc., it is applied to long-distance pipeline filters; but the door cover is often stuck and cannot be opened when it is opened,...
