Spring micro opening safety valve

Spring micro opening safety valve refers to a safety valve with a slight opening height, which does not allow sudden opening or closing to cause "water hammer" phenomenon, mainly used for liquid media; His typical feature is that the import and export ports have the same caliber. The main difference between full opening safety valves and micro opening safety valves lies in their opening height. Generally, the opening height of micro opening safety valves is 1/20~1/40 of their seat throat diameter, while the opening height of full opening safety valves is more than 1/4 of their seat throat diameter. The spring micro opening safety valve produced by Shanghai Meiyan Yi Pump Valve is an automatic safety valve that protects pipeline equipment. Its main working principle is that when the pressure inside the pipeline equipment reaches the set value, the valve automatically opens slightly to release pressure. When the pressure drops to the set value, the valve closes by the spring pressure return seat, ensuring that the pressure of the pipeline equipment does not exceed the predetermined value.
