Problems solved by technology

[0002] Generally, the commonly used manholes for high-pressure vessels are external, sealed with flange covers and gaskets, which take up a lot of external space, and require pre-tightening bolts, resulting in poor sealing. At the same time, it is troublesome to disassemble the gaskets, and the maintenance cost is high, which affects the high-pressure resistance. performance

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0027] Such as figure 1 with 2 The shown high-pressure vessel 1 with an inner-opening sealed manhole structure includes a cylindrical cylinder body 3, and the upper and lower sides of the cylinder body 3 are circular upper head 2 and lower head 4. In this embodiment, the upper seal The head 2 has a circular manhole 5, and the inside of the upper head 2 is pad-connected with a manhole cover 6 corresponding to the manhole...

Abstract

The invention discloses a high-pressure container with an inwards-opened sealed manhole. An inwards-opened sealed manhole structure comprises a cylinder. The upper portion and the lower portion of the cylinder are provided with an upper seal head and a lower seal head respectively. The manhole is formed in the upper seal head or the lower seal head. The manhole is round. A manhole cover which corresponds to the manhole is connected with the inner portion of the upper seal head in a cushioned mode. The manhole cover is used for sealing the manhole. The manhole cover is opened towards the inner portion of the upper seal head along the cushioned connection portion. The inwards-opened sealed manhole structure further comprises a manhole cover pressing device which is used for fixing and pressing the manhole cover. The inwards-opened sealed manhole structure is good in sealing performance; by the adoption of the inwards-opened sealed manhole structure, occupancy of external space can be reduced, maintenance is convenient, and the manufacturing cost and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of pressure vessels, in particular to an inwardly sealed manhole device. Background technique [0002] Generally, the commonly used manholes for high-pressure vessels are external, sealed with flange covers and gaskets, which take up a lot of external space, and require pre-tightening bolts, resulting in poor sealing. At the same time, it is troublesome to disassemble the gaskets, and the maintenance cost is high, which affects the high-pressure resistance. performance. [0003] In order to solve the above problems, the present invention provides an inwardly sealed manhole and a high-pressure vessel with the manhole. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the existing situation. Its purpose is to provide an inwardly sealed manhole and a high-pressure container with the manhole, which have good sealing performance, can reduce the occupation of external...
