Boiler safety valve installation method

Boiler safety valve installation methods which, if there cantaloupe boiler safety valve installation method statement, boiler safety valve installation Daquan - Wuhan far Mingfeng technology to provide boiler safety valve installation and precautions before installing the boiler safety valve, by professional technical The system features staff, on the basis of compliance with local national standards on safety valve to make the right selection. Set boiler safety valve should note the following: 1. The container with gas, liquid two-phase materials when the boiler safety valve should be installed in the gas phase portion. 2. boiler safety valve for venting flammable liquid, boiler safety valve outlet should be connected to the tank accident. When the discharge of the material is a high temperature fuel, its receiving container should have the appropriate protective equipment. 3. General boiler safety valve may be vented, the vent should be one meter higher than the operator (m) or more and not toward the fire place 15 meters (m) or less, emitting sparks and high temperature equipment location. Interior equipment, Boiler Safety container roof vent should be drawn, and the roof above two meters (m) or more. 4. When the boiler safety valve inlet have cut off valve, cut off valve should be in a normally open state, and to be seals, to avoid mistakes. 5. The boiler safety valve may be mounted horizontally or vertically, but not upside down installation, the boiler safety valve body marked flow direction, the installation must be strictly adhered to. Boiler safety valve inlet and outlet piping (1) boiler safety valve between the boiler or pressure vessel connecting pipe and fittings through-holes, its cross-sectional area of ??the cross-sectional area of ??not less than imports boiler safety valve; if the boiler safety valve to share a few imports and the pipe, the flow of the inlet pipe cross-sectional area is not less than the boiler safety valve inlet cross-sectional area. (2) boiler safety valve and the boiler drum, in general shall be installed between the manifold shutoff valve, or access to steam extraction pipe. Boiler safety valve should be installed on top of a heat source, or within one meter of water pipes safe distance between the pressure vessel and generally should not be fitted with a shutoff valve or other extraction tube; for costumes toxicity level is extremely high, high, moderate hazards, pressure vessel flammable, corrosive, viscous media or valuable media by the use of the unit in charge of the pressure vessel technical supervisor approval, and to develop reliable preventive measures before the safety valve between the boiler and pressure vessel fitted with a shutoff valve. During normal operation of the pressure vessel, the cut-off valve must be kept fully open, add seals or locks. As of structure and path valves, safety relief should be without prejudice to the boiler safety valve. (3) using a spring-type boiler safety valve threaded connection, to connect with the short threaded pipe, while the short pipe and simplified, philatelic box to use welded connections. (4) The boiler safety valve to be fitted with a discharge pipe. Discharge pipe to avoid twists and sharp turns to minimize drag. To discharge tube through a safe place, and there is enough flow area to ensure the exhaust flow. For a chemical reaction can interact boiler safety valve, a discharge pipe can not be shared; when the boiler safety valve mounted on the corrosive, flammable gas equipment, should also take anti-corrosion or anti-fire explosion measures emissions; when loaded located within the boiler safety valve equipment for toxic media, and the vapor density of the medium is greater than the density of air, from the media and steam boiler safety valve discharge to be introduced into the closed system, and recovering from a closed system into production use. (5) The boiler safety valve discharge pipe to be fixed, so that the boiler safety valve so as not to generate excessive additional stress or cause vibration. (6) The open-air installation of boiler safety valve to be provided to prevent the temperature is below 0oC, the medium contained in the water freezing inside the valve and measure the impact reliable boiler safety valve emissions. Wuhan Boiler safety valve looking away Ming Fung, Ming Fung Ltd. Wuhan far exclusive agent in Taiwan SS boiler safety valve, the National Low wholesale and retail SS boiler safety valve, DN15-DN50 quantities, quality and cheap, quality of products sold Problems year replacement, look forward to cooperation with your company. Taiwan SS boiler safety valve is mainly used in steam boilers, dyeing machinery, clothing steaming hot machine machine, leather machinery, chemical corrosion machinery and food machinery, brass and stainless steel, the working medium is air, steam, water, etc., which The main role is to protect the stability of the system pressure below the set pressure, when the system exceeds the set pressure boiler safety valve automatically opens to release the pressure. Taiwan professional manufacturer of boiler safety valve design and manufacturing, precision manufacturing processes, sold at home and abroad in more than 100 countries. Boiler safety valves are automatic valves, mainly for boilers, pressure vessels and piping, control pressure does not exceed a predetermined value, for personal safety and equipment operation plays an important protective role.
