What should you pay attention to when setting up Check Valve?

The Check 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 outside the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. valve. Check Valve are automatic valves that are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important role in protecting personal safety and equipment operation. Note: Check Valve must be pressure tested before use.

The following points should be noted when setting up the Check Valve:
(1) Containers and Check Valve should be installed for liquid materials in the gas phase.
(2) To discharge flammable liquids from the Check Valve, the outlet of the overflow valve should be connected to the tank. When relieving materials from high-temperature fuels, the receiving container should have appropriate protective facilities.
(3) General Check Valve can be vented, and the vent port operator should be 1 meter (m) high and should not exceed 15 meters (m) within the open flame, trigger site and high-temperature-resistant equipment. For indoor equipment, the container with Check Valve exhaust nozzle should be on the roof, and the high roof should be 2m (m) or more.
(4) When the Check Valve inlet blocks the valve, the closing valve should be in the open state and should be sealed to avoid errors.
