Description

Sanitary fire-retardant breather valve for tank and sanitary storage tank

Technical Field

The utility model relates to the technical field of fire-retardant breather valves, in particular to a sanitary fire-retardant breather valve for a tank and a sanitary storage tank.

Background

The fire-retardant breather valve is widely applied to an organic solvent storage tank, is an energy-saving product for maintaining the air pressure balance of the storage tank and reducing the volatilization of media, and fully utilizes the pressure-bearing capacity of the storage tank to reduce the discharge of the media. When the pressure of the medium in the tank is within the control operation pressure range of the breather valve, the breather valve does not work, and the tightness of the storage tank is kept; when medium is replenished into the tank, the pressure of the upper gas space in the tank is increased, and the operation positive pressure of the breather valve is reached, the pressure valve is jacked up, and gas escapes from the exhalation port of the breather valve, so that the pressure in the tank is not increased continuously; when the medium is pumped out of the tank, the pressure of the upper gas space in the tank is reduced, and when the operation negative pressure of the breather valve is reached, the negative pressure valve body of the breather valve is jacked up by the atmosphere outside the tank, so that the external gas enters the tank, the pressure in the tank is not reduced continuously, and the pressure in the tank and the pressure outside the tank are balanced.

However, in the industries of food, pharmacy and the like, a liquid medicine transfer tank containing an organic solvent not only requires that gas entering the tank be subjected to sterile filtration, but also that gas outside the tank be collected and then discharged to the atmosphere after being qualified by an organic waste gas treatment device. The traditional fire-retardant breather valve has the advantages that the air inlet and the air outlet are open, or exhaust gas cannot be collected, or the inlet gas cannot be filtered, or both the air inlet and the air outlet cannot meet the requirement of using conditions. The clamping sleeve type flame arrester only has the function of fire resistance, when the transfer storage tank does not pass in and out materials, the transfer storage tank cannot be closed, and the overflow of gas in the tank cannot be prevented, particularly when the exhaust ports of the storage tanks are converged, cross contamination is extremely easy to cause, and quality risks are brought to food and medicine production. In addition, as the ventilation performance of the microporous filter element of the air inlet can be reduced along with the use times and frequency, negative pressure is very easy to generate in the tank when the normal pressure container is in use, when the negative pressure value exceeds the design strength of the container, the tens of millions of containers are instable, the phenomenon that the tank body deforms and even is imbibed occurs, the loss of materials is caused, and the production safety is also endangered. Although negative pressure relief valves are installed on some normal pressure containers, the device is only installed on the tank body, and an air filtering device and a fire retarding device are not installed, so that after the negative pressure relief valves are started, medicines are at risk of being polluted, and once a fire disaster occurs, flames cannot be effectively isolated, and dangerous accidents occur.
