spring micro-opening external thread safety valve
It is a safety valve that uses spring force to realize micro-start, which is mainly used to control the pressure inside the system or equipment to prevent damage to the system or equipment due to excessive pressure. Its working principle is to control the opening and closing of the valve based on the elastic force of the spring and the pressure of the medium. When the pressure inside the system or equipment exceeds the set value, the elastic strength of the spring is overcome, and the safety valve begins to slowly open to release the overpressure gas or liquid; When the pressure is reduced below the set value, the elastic force of the spring regains its dominance, allowing the safety valve to close slowly, thus ensuring that the internal pressure of the system or equipment is maintained within the normal range
Structural characteristics
compact structure : The spring micro-opening external thread safety valve is light and compact, easy to install and maintain.
high sensitivity : Because the spring is used as the control element, the safety valve has a high sensitivity and can quickly respond to pressure changes inside the system or equipment.
widely applicable : suitable for petroleum, chemical, electric power, shipbuilding and other industrial fields, suitable for a variety of high temperature and high pressure protection equipment and systems.
easy installation : the external thread connection enables the safety valve to be installed without additional flanges or other connectors, simplifying the installation process
spring micro-open external thread safety valve is widely used in various industrial fields, especially in petroleum, chemical, electric power and shipbuilding industries. The safety valve adopts spring micro-opening external thread structure, so that it can be opened and closed slightly under a certain pressure, so as to achieve safety control. The external thread connection makes installation and removal easier
Application scenario
petroleum industry : Used in oil mining and processing equipment to ensure safe operation under high pressure environment.
chemical industry : Used in chemical production equipment to prevent accidents caused by high pressure.
electric power industry : used for power generation and transmission equipment, to protect the system from high pressure.
shipping industry : All kinds of equipment and pipelines for ships to ensure navigation safety
