SS valve looking away Ming Fung Wuhan, Wuhan far Ming Fung Ltd. is located in Hongshan District of Wuhan City, Wuhan major enterprises for wholesale and retail all kinds of domestic safety valve, safety valve, air conditioning, boiler safety valve, etc., and the sole agent Taiwan SS valve, the National Low wholesale and retail valve, DN15-DN50 quantities, quality and cheap, the sale of product quality issues Baohuan, look forward to cooperation with your company. Taiwan SS 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, and its main role is to protect the stability of the system pressure below the set pressure, when the system exceeds the set pressure relief valve automatically opens to release the pressure. Taiwan's professional valve manufacturers design and manufacturing, precision manufacturing processes, pressure up 4MPA, and high temperature 185 degrees, low temperature of minus 45 degrees, take off pressure can be easily set into 0.3-10bar, 10-25bar and 25-40bar and 0.1-50bar and 0.1-110bar, covering the majority of applications, simple installation, there is an obvious feature is much cheaper than other imported safety valve, quality far more than similar safety valve, a one-year replacement commitment , sold at home and abroad in more than 100 countries. SS valve Technical parameters: Material: Bronze / Stainless steel Diameter: DN15-DN50 maximum working pressure: 110bar Working temperature: -196-350 ℃ Relief Pressure: 0.1-110bar safety valve safety valve opening and closing parts defined by the external force in normally closed state, when the device or media pressure inside the pipe rises above a predetermined value, the pipeline or equipment by medium pressure exceeds a predetermined value to the outside of the system to prevent the emission medium. Safety valves are automatic valves, mainly used in boilers, pressure vessels and piping, control pressure does not exceed a predetermined value, for personal safety and equipment operation plays an important protective role. SS valve safety valve works is directly dependent on the medium pressure to overcome the force generated by acting on the poppet valve open so that the mechanical load acting on the valve mechanical load mainly from the hammer or spring, this almost The mechanical load is fixed. To ensure the sealing performance of the valve, must seat sealing surface and valve sealing surface flatness and surface roughness, there are strict requirements. In spring safety valve for example: works should be pressure = pressure X area. Pressure is the pressure of the spring, the area is the sealing surface area. When the pressure in the sealing surface of the sealing surface area is formed by multiplying the upward thrust is greater than the spring pressure, the spring is compressed, the sealing surface is opened by the pressure relief vent. SS valve classified according to different media discharge mode, the valve can be divided into fully enclosed, semi-enclosed and open, three. According to the maximum height of the valve opening of the safety valve flow channel diameter ratio to divide the closed valve can be divided into spring inching safety valve two kinds of high-pressure relief valve and the spring. Classification according to the action principle can be divided into direct-acting valve and non-direct-acting valve. Whether the pressure can be adjusted according to classification, can be divided into fixed and adjustable safety valve and adjustable safety valve safety valve safety valve should note the following: (1) there is gas in the container when liquid two-phase material safety valve should be installed In the gas phase portion. (2) safety valve for venting flammable liquid outlet valve of the tank should be connected to the accident. When the discharge of the material is a high temperature fuel, its receiving container should have the appropriate protective equipment. (3) general safety valve may be vented, the vent should be above the fire site operator 1 meter (m) or more and not toward 15 meters (m) or less, emitting sparks and high temperature equipment location. Indoor equipment, safety containers should lead roof vent and the roof above two meters (m) or more. (4) When the inlet valve has cut off valve, cut off valve should be in a normally open state, and to be seals, to avoid mistakes. Import and Export Pipeline (1) safety valve and connecting pipe and through-hole fittings between boiler or pressure vessel, the cross-sectional area of ??not less than the cross-sectional area of ??the valve imported; if several valves share one inlet duct, the inlet pipe of and the flow area of ??not less than cross-sectional area of ??the inlet valve. Drum (2) safety valves and boilers, among the tanks - like shutoff valve shall be installed, or access to steam extraction pipe. Between the valve and the pressure vessel - like not installed shutoff valve or other extraction tube; for costumes toxicity level is extremely high, high, moderate hazardous, flammable, corrosive, viscous medium or precious media pressure vessel, through the use of pressure vessel technology unit heads responsible for approval, and to develop reliable preventive measures before between the valve and the 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 valve shall be without prejudice to the. (3) using a spring-loaded 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 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 the safety valve can interact to produce a chemical reaction, can not share a discharge pipe; when the valve is mounted on the corrosive, flammable gas equipment, should also take anti-corrosion or anti-fire explosion measures emissions; when installed security valve equipment for toxic media, and the vapor density of the medium is greater than the density of air, from the media and steam safety valves discharged to be introduced into a closed system, and recovering from a closed system into production use. (5) The safety valve discharge pipe to be fixed so as not to have too much of a safety valve or the additional stress caused by vibration. (6) The open-air installation of safety valve, to be provided to prevent the temperature is below 0 degrees, the medium contained in the water freezing inside the valve and affect safety valve reliably measure emissions. (7) The safety valve medium crystallization temperature higher than the lowest ambient temperature, the valve must be provided with insulation jacket, and install insulation purge steam safety valve to prevent the media crystallization blockage, affecting the normal operation performance of the valve. Import and export pipeline safety valves must be designed with a steam jacketed pipe insulation or increase the insulation with steam pipes, to prevent crystallization medium clogging pipes. 1 safety valve maintenance. Hammer safety valve should prevent their own mobile devices and limit leverage deviant lead frame, spring safety valve should lift the handle and prevent casual twist adjusting screw means. 2.
