- Maintenance method of stainless steel ball valveStainless steel ball valve is a commonly used valve instrument, mainly used to cut, distribution and change the direction of the flow of media, with a simple structure, small size, light weight, small fluid resistance, convenient maintenance and so on. Stainless steel ball valve in the use of the need for a certain maintenance, you can ensure the normal operation of the stainless steel ball valve. So how to maintain the stainless steel ball valve, today's small make up to introduce the stainless steel ball valve maintenance method.Maintenance method of stainless steel ball valve:First: after the rough finished product, after pickling, must be washed clean, if there is sand hole or perforation, should use the argon arc welding to the gas protection welding. And then polished, and then solid fusion processing;Second: finished products, processing pressure after the completion of. Should be washed with water to join the anti rust powder.Third: in the transport process as far as possible tIndustry News July 27, 2016
- System of powder forging technologyTraditional ordinary die forging and machining method has been difficult to meet today's cars, motorcycles and other industrial production of high quality, high precision, high efficiency, low consumption and low cost requirements.Powder forging process is powder metallurgy process and organic combination of precision forging and developed a market competitiveness for a less, no cutting metal processing method.Powder forging metal powder as raw material, through preform pressing, heating it in a protective atmosphere, the blade forgings as forging blank in press and implementation without flash precision die forging, get the same as the ordinary die forging density and complicated shape precision forgings.Powder forging process requirements:1, ingredients and mixing.According to the different products of powder material and performance requirements, select the appropriate low alloy steel powder, after batching calculation and accurately according to powder weight, placed inside the mixIndustry News August 25, 2016

- The laser welding heat treatment do you know?In laser welding process of stainless steel, do you usually need to heat treatment after welding, especially the martensite and ferrite stainless steel, select the correct preheating before welding and welding post-processing is a necessary condition to ensure the quality of laser welding machine for welding.So what stainless steel heat treatment after welding process?Heat treatment after welding of stainless steel tensile strength, creep limit and the influence of heat treatment temperature and holding time.The influence of heat treatment after welding of stainless steel impact toughness on different steel grade are different, generally stainless steel heat treatment process to choose a single high temperature tempering after welding or high temperature normalizing and tempering process:1, high temperature normalizing and temperingFor welding joint by normalizing plus high temperature tempering heat treatment.This is because the welding seam and heat affected zone, coarse grains, theIndustry News August 26, 2016
- Five measures of full welded ball valve welding deformationAll welded ball valve in the welding process will produce about body and body seat with location in the size of the deformation, in order to prevent welding deformation, so the welding process should take effective preventive measures, a total of 5 points, specific as follows:1,Full welded ball valve welding should be used when the high energy source of heat.2,Choose reasonable technological parameters and groove form and the low energy input.3, Restrictions, and narrow welding heating area, forced cooling water or copper plate weldments.4, Selection of fine wire, low speed, control temperature in each layer between 50 ~ 80 ℃.5, Reasonable arrangement of assembling and welding sequence.The above is all welded ball valve several effective methods to welding deformation, hoping to bring help to you.Industry News August 24, 2016
- Casting is not just to haveCasting structure design should accord with the requirement of machine equipment itself and machining technology requirements, should also meet the requirements of the casting process, casting structure design should pay attention to the following:A, to facilitate manufacturing model, core box and style:1,the appearance of the casting should strive to simple, in order to draw, should try to make the casting parting surface is flat, and the smallest number;2,to the inner cavity of the casting, casting no or little use core, when using core, should be the support, the fixed and exhaust sanding, should have enough technology hole when necessary;3,inner and outer side for casting and strengthening rib structure, should be in the draw direction has a certain slope structure;4,convex parts and casting on the casting body should not differ too much, had better take the same height, the same distance on the surface of the close several convex sets, best into convex part of the whole.Second, toIndustry News August 31, 2016

- Different types of valve characteristicsType of valve has a lot of, each valve has its own characteristics, you are below summarizes the operating characteristics of different valves.1, Why easy oscillation when small open of the two-seater valve work. For single core, when the medium is away, valve stability is good;When the medium is flow closed type, the stability of the valve.Two-seater valve has two valve core, the valve core flow closed, valve core in the flow, so that when you are working in a small open degree, flow closed type of valve core is easy to cause the vibration of the valve, this is the reason why two-seat valves cannot be used for small open degree work.2, Why double seal valve cannot be used as a cut-off valve. Two-seater valve core has the advantage of force balance structure, allow the pressure difference is big, but its disadvantage is that the two seal face not good contact at the same time, cause leakage.If it is used to cut off at artificially, mandatory, obviously the result is bad, even as itIndustry News August 24, 2016
