Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to a storage tank breather valve anti-clogging water seal filter assembly. Background Technology

[0002] A breather valve for a storage tank is a safety accessory installed on the top of the tank. Its main function is to regulate the pressure balance inside and outside the tank, preventing deformation or damage due to pressure changes and reducing the evaporation loss of the liquid inside. The breather valve plays a protective role in the tank system, ensuring that the tank is not damaged by excessively high or low pressure during normal operation. When the temperature inside the tank rises, causing the gas volume to expand and the pressure to increase, the breather valve automatically opens to release excess pressure and prevent damage to the tank due to overpressure; this process is called venting. Conversely, when the temperature inside the tank decreases, causing the gas to contract and the pressure to decrease, the breather valve opens to allow outside air to enter the tank, preventing collapse due to excessive vacuum; this process is called intake.

[0003] Currently, when the temperature inside the storage tank rises and excess pressure is released to vent gas, the discharged gas contains certain particulate impurities. When this unfiltered gas enters the breather valve, dust, particulate matter, and other impurities accumulate inside the breather valve, causing blockage of the valve's passage. This affects the normal opening and closing of the breather valve, thereby affecting its pressure regulation function. At the same time, impurities may also wear down the internal components of the breather valve, such as the valve disc and valve seat, leading to a decrease in the breather valve's sealing performance or even its inability to function properly.
