a sterile respirator

Abstract

The invention relates to an aseptic respirator, and in particular to an aseptic respiratory for a tank body. The invention provides an aseptic respirator simple for adjustment and capable of realizing aseptic inhalation and effectively protecting the tank body. The respirator is arranged on the tank body and comprises a main body consisting of, from top to bottom, an upper cavity, a middle cavity and a lower cavity. A connecting cavity is connected with the side surface of the middle cavity, and the connecting cavity is communicated with an aseptic air source interface; a gas outlet valve assembly is arranged in the upper cavity, the upper part of the upper cavity is provided with a gas outlet communicating with the atmosphere, and the bottom of the upper cavity surface is provided with a bottom hole communicating with the middle cavity; and the gas outlet valve assembly comprises a pressure regulating nut, a pressure regulating bolt, an upper spring baffle plate, a spring, a lower spring baffle plate, an outlet gas pressing plate and a plurality of guide pillars. The invention can conveniently realize adjustment of the pressure balance point in the tank, and as well as ensures that a sterile state can be kept in the tank body during gas balance pressure supplement of the tank body; and on the other hand, the aseptic respirator avoids the internal shrinkage deformation of the tank body and can effectively protect the tank body.

Description

technical field [0001] The invention belongs to the field of tank respiration, in particular to aseptic respiration of tanks. Background technique [0002] The tank, as a storage container for gas or liquid, often feeds and discharges a large amount of material in daily use. In this way, it is necessary to control the pressure in the tank to prevent the tank from bursting or pressure when the pressure is too high. The tank is deformed when it is too small. In some special processing fields, while controlling the pressure of the tank, it is necessary to ensure the sterility inside the tank. Therefore, people usually add one or more sterile respirators outside the tank, such as national Bureau published on June 20, 2011 entitled "A Sterile Breathing Valve Applied to Daily Chemical Production Equipment" with the application number "201020251585.1". The steel ball in the safety relief device is lifted to discharge part of the gas to reduce the pressure in the tank. When the pre...
