Abstract

The invention discloses a flange with a hole and a safety valve pressure test system based on the flange with the hole. The flange with the hole comprises a flange plate. A duct concentric and coaxial with the flange plate is formed in the position of central axis of the flange plate. An external hole is formed in the side wall of the flange plate and communicates with the duct. By means of the beneficial effects that the flange is convenient to detach and install, the service life of the safety valve pressure test system is prolonged; a pressurization device communicates with a pipeline system in the safety valve pressure test system through the flange plate to conduct safety valve detection, and therefore the pressurization device can be repeatedly detached and installed, regulated overhaul and cleaning of the pressurization device in the safety valve pressure test system are achieved, the installation cost is further reduced, and the installation process is simplified. The gas tightness of the safety valve detection system cannot be influenced by installation and detachment of a pressurization system in the safety valve pressure test system based on the flange with the hole, and the detection result of the safety valve pressure test system is accurate.

Description

technical field

[0001] The invention relates to the field of safety valves, in particular to a perforated flange and a safety valve pressure test system based on the perforated flange. Background technique

[0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. ;When the medium pressure value is higher than the specified value, the safety valve will automatically open, and the excess medium will be released to reduce the internal pressure. When the internal pressure value drops to the specified value, the safety valve will automatically close and the discharge will stop. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipel...
