The function of gas emergency solenoid valve, installation and maintenance of gas emergency solenoid valve

The role of the gas emergency solenoid valve. The gas emergency shut-off valve, also known as the solenoid valve, is a safety emergency shut-off device for gas pipelines. It can be connected to the gas leakage alarm system, or to the fire protection and other intelligent alarm controller terminal modules to achieve on-site Or remotely cut off the gas source automatically or manually;the solenoid valve has the function of automatically shutting off the valve and cutting off the gas through strong vibration to ensure the safety of gas use. After closing the valve, personnel must go to the site to confirm and eliminate leaks, and then open it manually. Connected to combustible gas leakage monitoring equipment. When the instrument detects a leak of combustible gas, it will automatically and quickly close the main gas supply valve, cut off the supply of gas, and promptly prevent the occurrence of a vicious accident. Connect to the extreme temperature (or pressure) safety controller of the thermal equipment. When the temperature or pressure at the detection point in the equipment exceeds the set limit value, the air supply valve will be automatically and quickly closed to stop the fuel supply. Connected to the central fire leakage instrument system of high-rise buildings. When a fire breaks out in the building, the gas supply in the building will be automatically cut off to prevent accidents. A gas emergency shut-off valve is installed in the gas supply pipeline network of the city or factory, which can be centrally controlled in the central control room and remotely controlled to emergency shut down the pipeline gas supply at the accident site. It is suitable for combustible gases such as coal gas, natural gas and liquefied petroleum gas, and is widely used in gas supply pipe network systems, gas thermal energy factory workshops, gas boiler rooms and safety facilities in residential residences. Gas emergency solenoid valve installation 1. Before installation, confirm that the valve has no obvious damage;carefully check the nameplate to confirm that the product diameter matches the pipeline;confirm that the working pressure should be greater than the maximum pressure during normal operation of the pipeline;2. The front end of the valve inlet A maintenance ball valve should be installed;3. The valve should be installed horizontally, with the valve opening lever pointing upward;(valvees with a nominal diameter of DN80 and below can be installed vertically);4. When the nominal diameter is greater than DN50, the valve should be installed horizontally on both sides of the valve. Install the pipe bracket at the end;5. When installing, the dustproof paper at both ends of the valve body should be removed;6. The valve should be installed after the pipe has been purged clean, and a filter should be installed at the air inlet end;7. When installed outdoors for use , protective measures should be taken (such as setting up a dust cover). Routine maintenance of gas emergency solenoid valve 1. The pipeline pressure test should be carried out in the open state, and the pressure test in the closed state is prohibited;2. Please keep the valve body clean;open the protective cover and do not open or lose it;3. The valve should be inspected regularly Carry out air tightness inspection, use soapy water to check the air tightness of the valve opening lever and each connection port. If there is a malfunction or air leakage, the maintenance valve should be closed and the maintenance unit should be notified for inspection;the inspection period should not exceed one year. 4. The valve action function should be tested regularly, and the valve can be closed and opened normally by controlling the valve closing on the linkage control equipment;the test period should not exceed one year. Tips: In addition to industrial settings, home users can also install small solenoid valves for household use. The solenoid valve is connected to a gas alarm, which can effectively protect the safety of household gas. The above is the function of the gas emergency solenoid valve. The installation and maintenance of the gas emergency solenoid valve are introduced. If you want to know more relevant information, please log in to Sunway Pneumatic www.diancifa.cc.
