Shanghai Huanyao Valve Co., Ltd.

Overview of stainless steel all-weather breathing valve:
-type stainless steel breathing valve is used on oil and liquid tanks to eliminate the positive and negative pressure gases in the tank to facilitate the entry and exit of liquid in the tank. If the tank is not equipped with a breathing valve, There are certain obstacles in the entry and exit of liquids, which may cause tank deformation and vibration. The product has a reasonable design, simple structure, and is easy to use. It is an indispensable product for storage tanks.
Characteristics and performance of stainless steel all-weather breathing valve
． The new all-weather oil storage tank breathing valve housing is made of cast steel with good corrosion resistance
. The valve disc is made of stainless steel and is made of four materials with good low temperature resistance and antifreeze performance
. The structure is simple, easy to maintain, safe and convenient
. The performance of the new all-weather oil storage tank breathing valve has been tested and fully complies with the standards and regulations of the Ministry of Petroleum Industry. Scope of application of stainless steel all-weather breathing valve
． The new all-weather oil storage tank breathing valve is suitable for storage below. Class A oils and below. Storage tanks for Class B oil products such as gasoline, benzene, toluene, kerosene, light diesel oil, crude oil, oil, food oil and other oil products and chemical products with the same properties.
． It can be used in conjunction with the new corrugated oil storage tank flame arrester and hydraulic safety valve.
Main technical parameters of stainless steel all-weather breathing valve
Operating pressure: Positive pressure: + (mm water column) Negative pressure: - (mm water column) When ordering, please indicate the product name, model, specification and pressure level.
Maintenance and repair of stainless steel all-weather breathing valve
In order to ensure that the performance of the new all-weather breathing valve reaches the purpose of safe use, the breathing valve should be inspected and maintained regularly:
. Check whether the pressure valve disc and vacuum action are flexible, and whether the contact surface of the guide rod and valve sealing ring is damaged
. When reinstalling the pressure valve disc and vacuum valve disc, ensure that the contact surface is tight and the guide rod can be lifted and lowered flexibly
. When a new valve is started, the anti-vibration material on the valve disc should be removed before installation, otherwise the breathing valve will malfunction.
． Due to humid weather, windy and sandy conditions, the storage tank cannot be used for oiling when the temperature reaches zero degrees. In urgent production, the oil gauge hole and other gas supply products must be opened first to maintain the safety function of the storage tank.
． The oil dip hole must be opened before the breathing valve can work normally to feed oil.
