Description
Technical Field
The utility model relates to a relief valve especially relates to a sewer line pressure control system.
Background
The safety valve is a special equipment for overpressure protection of pressure system, and is an automatic valve. When the system pressure reaches the setting pressure, the medium self-force is utilized to discharge a certain rated amount of fluid without any external force, so as to prevent the pressure in the system from exceeding a preset safety value. When the pressure returns to normal, the valve is closed again to prevent the medium from flowing out continuously, the types of safety valves are various, wherein the safety valve used for the air bottle for the ship needs to be opened slightly, and the opening stroke height is as follows: less than or equal to 0.05d0, the opening or closing reaction speed of the valve needs to reach the requirement for a smaller stroke, and the force needs to be uniformly stressed in the process of pressing down the stable valve rod when the valve rod is closed, so that the valve flap is prevented from being closed unevenly, and poor sealing performance is caused.
