High-pressure container peep device

Abstract

The invention discloses a high-pressure container peep device, which comprises a peep cylinder body, an annular mounting seat arranged in the peep cylinder body, and a light transmission mirror embedded in the annular mounting seat, wherein the annular mounting seat has a truncated cone surface inner wall; the light transmission mirror has a truncated cone surface outer wall; the truncated cone surface and the truncated cone surface inner wall are matched in a cone surface self-locking sealed mode, and the higher the container pressure is, the larger the pressing force of the contact surface, and the better the sealing performance is. The outer wall of the annular mounting seat is provided with a mounting seat sealing ring groove; and the mounting seat sealing ring groove and the inner wall of the peep cylinder body are sealed via a radial sealing ring. The peep cylinder body is also internally provided with an external screw pressing ring, and the inner side end of the external screw pressing ring and the outer side end of the annular mounting seat are matched in an abutting mode. The high-pressure container peep device has the advantages that the structure is simple, assembly and disassembly are simple, the sealing is reliable, and the interchangeability is high, and problems that the pretightening force cannot be controlled, the mirror glass stress and strain change abruptly, the service life can not be predicted and the like can be solved.

Description

technical field [0001] The invention relates to a device for observing medium changes in equipment pressure vessels, in particular to a high-pressure vessel peeping device. Background technique [0002] It is often necessary to install a pressure vessel sight glass on the equipment pressure vessel. The pressure vessel sight glass, also known as the equipment sight glass, is a device used to observe the change of the medium in the container of chemical, petroleum, cosmetic, pharmaceutical and other industrial equipment. For example, our common liquefied gas storage tanks or tank trucks, gas-liquid phase reactors or reactors and other equipment pressure vessels need to be installed with equipment sight glasses to prevent accidents caused by overfilling or improper material reaction due to excessive feeding. balance. [0003] At present, the production of pressure vessel sight glasses in my country mostly follows the energy industry standard "Pressure Vessel Sight Glass-NB / T47...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects existing in the sight glass of the existing equipment, and provide a peeping device for high-pressure containers. Problems such as uncontrollable medium preload, sudden change of stress and strain of mirror glass, and unpredictable service life
