High pressure vessel peeping device

Abstract

The invention discloses a peeping device for a high-pressure container, which comprises a peeping cylinder body, an annular mounting seat arranged in the peeping cylinder body, and a light-transmitting mirror embedded in the annular mounting seat. The annular mounting seat has an inner wall of a conical table surface, and the light-transmitting mirror has an outer wall of a conical table surface. The outer wall of the conical table surface and the inner wall of the conical table surface form a self-locking and sealing fit of a conical surface. The higher the pressure of the container, the higher the pressing force of the contact surface The larger the size, the better the sealing performance. The outer wall of the annular mounting seat is provided with a sealing ring groove of the mounting seat, and the sealing ring groove of the mounting seat is sealed with the inner wall of the viewing cylinder by a radial sealing ring. An external thread compression ring is also arranged in the peeping barrel, and the inner end of the external thread compression ring abuts and fits with the outer end of the annular mounting seat. It has simple structure, easy assembly and disassembly, reliable sealing, and strong interchangeability, which can effectively solve the problems of uncontrollable pre-tightening force, sudden change of stress and strain of sight glass glass, and unpredictable service life in the traditional mirror structure.

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...
