Clamping block connecting and fastening structure for pressure container

Abstract

A clamping block connecting and fastening structure for a pressure container is provided with a first high neck, a second high neck, a sealing element and a fastening device. A first protruding shoulder is arranged on the outer circular face of the first high neck. A second protruding shoulder is arranged on the outer circular face of the second high neck. The sealing element is arranged between the first high neck and the second high neck. The fastening device comprises clamping blocks and a steel plate ring. The multiple clamping blocks are arranged on the periphery of the first high neck and on the periphery of the second high neck. The two ends of each clamping block are provided with clamping jaws. The clamping jaws at the two ends are clamped on the first protruding shoulder of the first high neck and the second protruding shoulder of the second high neck respectively. The outer side faces of the clamping blocks are coated with the steel plate ring and the clamping blocks are wrapped. The clamping block connecting and fastening structure can be suitable for the large-diameter detachable high-pressure container, the structure is light and convenient to use, materials are easily prepared, machining is convenient, cost is low, the problem that a connecting and fastening structure for the large-diameter detachable high-pressure container is not available in the prior art is solved, and a path is provided for development of the detachable high-pressure container in the large size direction.

Description

technical field [0001] The invention relates to the field of pressure vessels, in particular to a block connection fastening structure for a pressure vessel. Background technique [0002] According to the structure of the pressure vessel, the pressure vessel is divided into two types: detachable and non-detachable. The detachable pressure vessel can be disassembled into two or more parts without destroying the vessel. More than two parts, in order to load or take out internal parts and internal fillers (such as catalysts, fillers), or allow personnel to enter the interior of the container for inspection and maintenance. [0003] According to the design pressure of the pressure vessel p , Pressure vessels are divided into four pressure levels: low pressure, medium pressure, high pressure and ultra-high pressure (see TSGR0004-2009 "Safety Technical Supervision Regulations for Stationary Pressure Vessels" Annex A, Article A2). [0004] For low-pressure or medium-pressure vess...

Problems solved by technology

However, due to the irregular shape of the clamps, the clamps used for large-diameter high-pressure vessels need to be processed with large forgings, and the amount of machining and cutting is large. Not only is the material preparation not easy, the processing is difficult, time-consuming, and the cost is high High, so the clamp connection fastening structure is not suitable for large-diameter high-pressure vessels (for details, see the upper left column on page 118 of the first edition of "High Pressure Vessels" Chemical Industry Press, January 2003)

[0009] According to the existing technology and pressure vessel design specifications, when the diameter of the detachable high-pressure vessel exceeds Φ3200mm, there is no corresponding connection and fastening structure that can be used, which restricts the development of the detachable high-pressure vessel in the direction of large-scale
