Abstract
The invention discloses a stainless steel instrument pipe valve element, which comprises the following steps that sectional materials are cut to the required length by a cutting machine, the blanking length of angle iron with the length being 6m is 1mm, and the punching of phi12 round holes in the angle iron is completed on a punching machine. Before the hole punching, two angle iron brackets are manufactured in advance before the hole punching, the height of the brackets is aligned with a lower punching mold, transverse rods of the brackets adopt SHS60*5 square tubes, stainless steel angle iron with the length being 50mm can be welded onto the square tubes in advance, the stainless steel is not in contact with square tube iron elements, the accumulated error of the dimension between hole positions does not exceed 1.5mm, the round steel blanking length is 110mm, the excessive flashes and burrs are ground after the cutting, then, the 90-degree blanking bending is carried out on the punching machine, the angle error does not exceed 2 degrees, and the contact surface of the round steel and the angle steel needs to be roundly ground for reducing the welding quantity. The stainless steel instrument pipe valve element has the advantages that the stainless steel instrument pipe valve element cannot be easily eroded, the service life is longer than the service life of the traditional pipe valve element, the operation is simple, the manufacturing process is simple and clear, and the work efficiency of workers is improved.
Description
Technical field
The present invention relates to gauge pipe valve member, be specifically related to a kind of stainless steel gauge pipe valve member, belong to gauge pipe valve member and manufacture field.
Background technology
Stainless steel tube is safe and reliable, hygienic environment-protecting, economic and practical, the thin-walled property of pipeline and novel reliably, the succeeding in developing of method of attachment simply and easily, make it have the irreplaceable advantage of other tubing more, the application in engineering can get more and more, using can be more and more universal, promise well; Along with the enforcement of China's policies of reform and opening to the outside world, national economy obtains and increases fast, and town-property, public building and tourist facilities are built in a large number, proposes new requirement to hot water supply and domestic water supply.Particularly quality problem, people more and more pay attention to, and require also to improve constantly.This common pipe materials of coating steel pipe, because of its susceptibility-to-corrosion, under the impact of national relevant policies, will step down from the stage of history gradually, and plastic tube, multiple tube and copper pipe have become the common pipe materials of pipe-line system.But in many cases, stainless steel tube more has superiority, particularly the wall thickness thin-wall stainless steel that is only 0.6 ~ 1.2mm is in good system about drinking water, hot-water heating system and the water supply system of safety, health being put in the first place, has safe and reliable, hygienic environment-protecting, the feature such as economic and practical.By project practices at home and abroad prove water supply system combination property best, one of the tubing of novel, energy saving standard type, be also the very competitive water-feeding pipes of one, will to improving water quality, improve people's living standard and play unrivaled effect.
In building water supply piping, because coating steel pipe has finished century-old brilliant history, various novel plastics pipe and multiple tube are developed rapidly, but various tubing also also exists some shortcomings to some extent, far can not adapt to completely water supply piping needs and country to drinking water and the requirement about water quality.Therefore, relevant expert's prophesy: Building Supplies Water Pipe returns to the epoch of metal tube the most at last.According to external application experience, in metal tube, assert that thin-wall stainless steel is one of best tubing of combination property.
Steel pipe can be divided into stainless-steel seamless pipe and the large class of stainless steel welded steel pipe (seamed pipe) two, can be divided into according to the difference of manufacturing process: hot rolling, extruding, cold-drawn and this several fundamental type cold rolling, pipe and special pipe can be divided into again by section configuration, extensive use be round steel pipe, but also there are some square, rectangle, semicircle, hexagon, equilateral triangle, the special stainless steel steel pipes such as octagonal, hydraulic test all will be carried out to check its voltage endurance capability and quality for the steel pipe bearing fluid pressure, do not leak under the pressure of regulation, soak or be expanded to qualified, some steel pipe also will require to carry out flange test according to standard or demanding party, flaring test, flattening test, gapless stainless steel tube also claims stainless steel seamless pipe, make hollow billet by steel ingot or solid pipe billet perforated, then through hot rolling, make for cold rolling or cold group.The specification of seamless steel pipe represents with external diameter * wall thickness millimeter.
Summary of the invention

Technical scheme: for achieving the above object, the invention provides a kind of stainless steel gauge pipe valve member, comprises lower step:
A, with cutting machine cut type material to Len req, the positive 1 ~ 2mm of 6m long angle bar cutting length,
The angle bar cutting length of b, butt welding can bear 1mm, should ensure that cut surface is concordant, should grind off batch cutting edge of a knife or a sword, burr after cutting;
On c, angle bar, φ 12 circular hole completes on punch press.Make two angle brackets before punching in advance, bracket height and lower punch die are put down, and bracket cross bar SHS60*5 square tube, can descend the long stainless steel angle bar of 50mm to be soldered on square tube in advance, not allow stainless steel contact with square tube ironware; The punching position of perforate location angle bar on square tube, should careful inspection opening column pitch, and the accumulated error of hole interdigit size is no more than 1.5mm;
D, erection welding:
(1), control weld heat input output, adopt rational welding sequence, thus reduce component;
(2), because of distortion that welding stress causes;
(3), backing welding time throat depth should be as far as possible thin, fuse well with root, will become gentle slope shape when receiving arc, if any receipts arc shrinkage cavity, application sanding machine grinds off, must striking in groove, blow-out, should arc crater be filled up during blow-out, prevent crater crack;
(4), butt welding weld adopts double V-groove, and stainless steel nut weld two spot welding during welding within the scope of groove face and both sides 30mm is sewn to the loading and unloading of stainless steel angle bar;
E, postwelding correct: after structure manufacture completes, component should be carried out correcting deformed, bending and the side sway in the method gauge length direction adopting hammering to beat, forbid directly to beat stainless steel component with iron hammer, available wood cushion block separates, and the platform of placement member also should separate with cardboard or plastic cement, 6m long component side sway size is not more than 3 ~ 6mm.
The present invention is not easily by rain erosion, and service life is than the long service life of traditional pipe valve, simple to operate, and manufacture craft is simple and clear, improves the operating efficiency of staff.
Described round steel cutting length 110mm, should grind off batch cutting edge of a knife or a sword after cutting, burr, is then no more than 2 degree in punch press upper punch curved an angle of 90 degrees degree error, is to reduce welding capacity, and the contact surface of round steel and angle steel answers rounding, and it is more mellow and full smooth to be that pipe valve is taken a fancy to like this.
