    Product Description

    Micro-opening safety valve refers to a type of safety valve with a relatively small opening height and a relatively small discharge volume. Specifically, the specified opening height h of the valve disc is between d1 / 40 to d2 / 20 (d1 is the diameter of the throat of the valve seat). There are two types of valve sealing surfaces: flat and conical. Their discharge areas are calculated according to the area of the cylindrical surface or the cone curtain formed between the valve disc and the valve seat. The advantage is that the structure is simple, and manufacturing, maintenance and test adjustment are relatively convenient. It is suitable for occasions with small discharge, large back pressure and stable system pressure.


    This type of safety valve is mainly used for the safety discharge system of cryogenic liquid storage and transportation equipment. It has the characteristics of sensitive switching and reliable sealing, and is especially suitable for small volume equipment.
