Qufu zipper butterfly valve parameters

Qufu zipper butterfly valve parameters and principles Flanging and folding according to the 15mm flanging size, first fold the required flanging of the transverse welding of the air duct klik on the folding machine. After flanging, the length of each section of the air duct is (12101502) mm=1180mm, and then follow The side of the duct is long and square. Angle steel blanking and reinforcement frame prefabrication Determine that the angle steel specification used for the air duct reinforcement frame is 30303. According to the size of the air pipe, the stainless steel angle steel is blanked and welded by electric welding. After the air pipe group and the reinforcement frame are ready, the two stainless steel plates are aligned (the air pipe group is shown in the figure, and the reinforced frame that has been made is placed on the paired air pipe before welding. Safety measures Strictly check the licenses of special types of work, and carry out safety technical disclosure before implementation. It should be checked aluminium profile suppliers and confirmed that the power supply and voltage meet the requirements, and the grounding device is safe and reliable. The installed argon pressure relief valve and pipe joints must not be stained with grease. The test should be conducted to confirm the barrier-free and gas leakage. When using argon arc welding, the operator should wear a gas mask. When replacing the tungsten electrode, the power must be cut off. When grinding the tungsten tip, the operator must wear gloves and a mask to grind The dust that comes down should be removed in time, and the tungsten electrode should not be carried around. Appearance quality Surface quality The surface must be free of cracks, knots, folds and other defects whose depth exceeds the deviation of the nominal wall thickness. For defects that cannot be determined in depth, the grinding method should be used to completely remove and then measure. There shall be no pits with a depth of more than 6.4mm on the wall of the pit, and the length of the pit shall not exceed 5mm. If there are sharp scratches in the concave part, the sharp scratches should be worn away, and the depth of the depression should not exceed 3.2mm. Surface treatment and packaging Spiral ducts and fittings should be covered with a layer of plastic wrap before leaving the factory. After the product is galvanized on the surface, it must comply with the prescribed standards for storage, installation, use, maintenance and transportation. During the warranty period, spiral ducts and fittings are not allowed to have defects such as blistering, whitishness, loss of gloss, rust, scratches and bruises. The advantages of spiral ducts are as follows, a few points: the installation of simple spiral ducts reduces the connection points between the pipes, so that the leakage of the joint of the pipe can be reduced to a low level. Moreover, only one pipe joint is needed to connect the two spiral air ducts, and the connection of the traditional rectangular air duct requires a completely vertical double flange system. The standardized products of spiral duct fittings, including fittings and joints, have been produced in a highly automated, systematic, and industrialized quality control.

Therefore, it can be fed manually or by machine, and sometimes it may not be fed. Then whether it uses DC or AC depends on the welding material. Tungsten inert gas shielded welding is mainly used for welding thin and medium-thickness workpieces, with a wide range of materials, including alloy steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium and lead. Always adhere to the business tenet of 'Excellence, Quality Assurance, Customer First', integrity, strength and product quality are recognized by the industry, and we are dedicated to serving our customers Friends from all walks of life are welcome to visit the company, guide and negotiate business. Dezhou Rutong Electromechanical Equipment Co., Ltd. is willing to develop with you and develop a better tomorrow. Welding method of stainless steel air duct: It is very widely used, and the operation is simple, mainly relying on human conditioning, and the welding seam filling material is the electrode. Craft welding can almost weld all the materials, even in the outdoor, so it has good adaptability. Generally, direct current is used for welding. The electrode can be either a titanium electrode or a wire. Titanium electrode is relatively simple to weld, the weld is beautiful, and the welding slag is easily removed. But the disadvantage is that if it is not used for a long time, it is necessary to bake from scratch to prevent the accumulation of moisture. It belongs to gas maintenance welding. It belongs to gas maintenance welding. It is also an arc welding. Under the maintenance gas, the electrode is melted by arc. Metal electrode gas maintenance welding can be used for such materials as steel, non-alloy steel, low alloy steel and high alloy, and is widely used. But one thing, its maintenance gas must be active gas, such as carbon dioxide or mixed gas. The defect is that if welding is performed outdoors, the workpiece cannot be damp, otherwise it will affect the maintenance effect of the maintenance gas. The tungsten inert gas maintenance welding arc occurs between the tungsten welding wire and the workpiece, so the maintenance gas is required to be pure ya gas, and the welding wire is not charged, so it can be fed manually or by machine, and sometimes also No entry. Then whether it uses DC or AC power depends on the welding data. Tungsten inert gas maintenance welding is mainly used for welding thin and medium thickness workpieces. The scale of raw materials is very wide, including alloy steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium and lead. In order to make the cost of spiral duct machine manufacturers have to compress the business, strengthen the survival compression or the business with lower profitability, strengthen the core competitiveness, and strengthen the survivability of the enterprise is also the main. Now that we know that the primary task of an enterprise during the economic crisis is to survive, the enterprise needs to adjust its business structure and compress or eliminate businesses with lower profitability to concentrate resources on businesses that can be cashed out immediately. The spiral duct is generally divided into single pipe and double-layer insulation pipe, and its manufacturing process is basically the same except for some differences. First introduce the production process of single tube: put the strip on the rotating table and make it through the bite machine. Double-layer insulation tube: single-layer insulation tube production layer, single metal spiral jacket tube. Accessories include: intermediate joints, reducers, air inlets, 90 bends, S-bends, round and square. Previously the production was manual lofting, proofing, and the efficiency was very low. After adopting computer technology, as long as the technical data is input into the computer, and then according to the required accessories, the computer enters the information into the automatic plasma cutting machine, and the reverse cut material is made by different biting machines and welding machines. Between 0.2MM, it is easy to cooperate and has good sealing. Dezhou Rutong Electromechanical Equipment Co., Ltd. has always been 'making products with talents' as its purpose, determined to establish a corporate image of excellence, and wholeheartedly conduct extensive economic exchanges and cooperation with customers at home and abroad to create brilliant and greet a better tomorrow! Our business philosophy: take the market with quality, win customers with integrity, eager to worry about customers, think about what customers want, and supply and demand for mutual benefit.
