Description

TECHNICAL FIELD

[0001] The utility model relates to the field of breather valve detection, especially to a storage tank breather valve detection equipment. BACKGROUND

[0002] The breather valve is a device for controlling the pressure balance between the inside and outside of a sealed container, and is widely used in the fields of petroleum, chemical industry, storage tank, liquid storage and transportation, etc. Its main function is to prevent the container from generating a large pressure difference due to changes in the external environment, resulting in leakage, rupture or other safety accidents. When the internal pressure of the container exceeds the set value, the breather valve will automatically open to release excess gas, and when the internal pressure is lower than the external atmospheric pressure, it can also automatically suck in air to maintain the structural stability of the container. The design of the breather valve includes two major functions of pressure release and vacuum suction, which can effectively cope with the influence of environmental temperature and pressure changes.

[0003] According to the working principle, the breather valve can be divided into spring type, floating ball type, liquid level control type and other types, among which the spring type is the most common. Its application can reduce the damage to storage tanks, pipelines and equipment caused by pressure fluctuations, improve safety and prolong the service life of equipment. In addition, modern breather valves also have the characteristics of corrosion resistance, high temperature resistance and precise control, further enhancing their application value in industry.

[0004] Before leaving the factory and during use, the breather valve needs to be inspected and repaired to ensure that all functions of the breather valve are normal during use, and to check whether the pressure relief value and the suction pressure value are within the appropriate range. The detection method is to detect various values through the breather valve calibrator by pressurizing or inhaling. However, during detection, the traditional breather valve calibrator fixes the breather valve by manually pressing or cooperating with three sliding clamps. Manual pressing is very laborious, and the clamps themselves have no fixing method. When the output pressure is too large, the clamps will be pushed open and slide to one side, losing the clamping function and affecting the calibration effect. Therefore, a storage tank breather valve detection equipment is proposed to solve the above problems. UTILITY MODEL CONTENTS
