brief introduction of breathing valve

Sanitation breathing valve overall 304 stainless steel material, nominal pressure PN1.0-1.6Mpa, nominal diameter: DN15-DN100mm (1/2 "-4"), connection mode:Flanged type, quick loading type (optional customized), applied to the fermentation tank when the pressure of the medium in the sanitary breathing valve control operating pressure range, breathing valve does not work, to maintain the tightness of the oil tank, the valve inside and outside the overall stainless steel manufacturing;The high precision mirror polishing of the inner cavity and outer surface meets the requirements of health industry. It is widely used in food and beverage processing, pharmaceutical and chemical industry.

Detailed introduction

Health level of respiration valve is mainly used in the aseptic water tank, mixing tank, pharmaceutical water tank device, such as cut off for pure water, the direct touch of material liquid and air, when the pressure in the tank is too large, can through exudes, breathing apparatus is able to prevent the bacteria in the air, particles, dust pollution such as water or material liquid, can filter out bacteria and dust in the air, etc.

Operation principle

When a certain pressure is reached, exhale or inhale;The other is a simple inhale only, can be understood as the use of two appropriate pressure of the one-way valve.

Breathing valve is similar to one-way check valve, it can only exhale outward, not inhale inward, when the pressure in the system is increased, the gas will be vented outward through the breathing valve, to ensure the pressure of the system is stable.About the storage tank of toxic substances, there is no breathing valve or activated carbon filter and other processing equipment.

The working principle of

1. When the pressure of the medium in the tank is within the control operating pressure range of the sanitary breathing valve, the breathing valve does not work to maintain the tightness of the oil tank;

2. When adding medium to the tank, the pressure of the upper gas space in the tank is increased to reach the positive pressure of the operation of the breathing valve, the pressure valve is top open, the gas escapes from the breathing valve exhalation outlet, so that the pressure in the tank is not continued to increase;

3. When the tank is draw out medium, make the tank top gas pressure drop of the space, level of health for breathing valve operating pressure, open the atmosphere outside the tank will be breathing valve of negative pressure valve, the gas into the tank, the tank pressure will no longer continue to fall, let the tank and tank pressure balance, to protect the safety of the tank.
