1breathing valveProduct Introduction：

All-weather respiration valveUsed on oil and liquid tanks to eliminate positive and negative pressure gases inside the tank, making it convenient for liquids to enter and exit the tank If there is no breathing valve installed on the tank, there may be certain obstacles to the entry and exit of the liquid inside the tank, which may result in the tank

2. Breathing valveMaintenance and Care：

Used on oil and liquid tanks to eliminate positive and negative pressure gases inside the tank, making it convenient for liquids to enter and exit the tank If the tank is not loadedbreathing valveThere are certain obstacles to the entry and exit of liquids in the tank, which may cause deformation and vibration of the tank body. The design is reasonable, the structure is simple, and it is easy to use; It is a product of the storage tank.

Instructions for use:
Installed at the top of the storage tank, it solves the problem of positive and negative pressure gas inside the tank, so that the liquid in and out of the tank is not obstructed. When the external liquid is input into the tank, a large amount of gas is exhaled outward (called positive pressure). When the liquid inside the tank is exported, it must be sucked into the tank from the outside air (called negative pressure). When stopping workbreathing valveAutomatic shutdown will not cause leakage of liquid and gas from the tank, ensuring the quality of the liquid inside the tank is effectively guaranteed.

• Performance characteristics of breathing valves:

1) Simple structure, easy maintenance, safe and convenient;
2) The valve disc is made of PTFE material, which is resistant to low temperatures and has good anti freezing performance;
3) New all-weather technologybreatheThe shell is made of stainless steel, cast steel, and aluminum alloy, with good corrosion resistance;
4) New all-weather technologybreatheThe performance * complies with the standard SY7511-87 of the Ministry of Petroleum Industry.

4Breathing valve selection：

The code for the breathing valve is represented by HX, and HXF is the code for the fire-resistant breathing valve.

The respiratory valve type codes are classified based on whether there is a connection at the inhalation and exhalation ports, with a total of 8 types, as shown in the table:
