Description
Technical field
The utility model is related in high alloy steel pipe welding process to its internal argon-filling protection technique, it is specifically a kind of for small
Bore high alloy steel pipe internal argon-filling protects tool.
Background technology
In the installation of Generator Set, the specification of high alloy small diameter tube is more, weld bond substantial amounts, the weldering of conventional pipeline
Argon filling technology is connect using mode is filled entirely, entire inner cavity of pipe is made to be full of, this argon filling mode quality of protection is unstable, argon filling effect
The quality of fruit depends on the size with inner cavity of pipe.Argon gas is more used in this mode, uneconomical.Therefore occur existing frequently-used
External argon filling mode.I.e. by doing gas chamber inside pipeline, argon filling is carried out using tools such as needle-like mouths.Current so-called argon filling tool
Typically it is made using thinner gauge pipe and copper pipe.It is single, coarse, be not easy to take care of, while argon flow amount used is not
It can control, argon gas used is still excessive, uneconomical.The utility model is provided inside a kind of small-bore high alloy efficiently, economic
Argon-filled protection tool.
Utility model content
The purpose of this utility model is to provide one kind protecting tool for small-bore high alloy steel pipe internal argon-filling, overcomes existing
Having traditional argon filling tool to adjust, flow is difficult, argon gas loss is more, to the matter of economic, the continual and steady protection root of weld
Amount.
The technical solution of the utility model is：
The utility model provide it is a kind of protecting tool for small-bore high alloy steel pipe internal argon-filling, including it is sequentially connected not
Become rusty steel argon filling mouth, gas flow regulating valve, silica gel hose and C formula Pneumatic quick connectors.
The stainless steel argon filling mouth is the flat and stainless steel tubule with venthole in one end, 4~8mm of capillary diameter, ventilation
It is 2 ~ 4 that bore dia, which is not more than 2mm and quantity, and the other end is welded with gas flow regulating valve.
The gas flow regulating valve is the acetylene regulating valve seat that waste and old cutter removes, one end and stainless steel argon filling mouth
Welding, the other end are connect with silica gel hose.
The silica gel hose is white hose of the internal diameter no more than 10mm and length is not less than 500mm.
The C formulas Pneumatic quick connector, is made of SH20 females and PH20 male connectors, and one terminates silica gel hose, the other end
Argon gas is connect for gas skin tube.
As shown from the above technical solution, the utility model utilizes gas stream by improvement, assembling to stainless steel argon filling mouth
Adjustable valve and C formula Pneumatic quick connectors, have been well controllled the flow of argon gas, and continual and steady is supplied by gas vent, protect
The quality of the root of weld is demonstrate,proved.Increased silica gel hose is compared simultaneously has better resistance to electric arc, resistance to height using common leather hose
Temperature characteristics, and it is more soft, light, it is suitble to the flexible operating of each position.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the usage state diagram of the utility model.
Reference numeral：
1- stainless steel argon filling mouths, 2- gas flow regulating valves, 3- silica gel hoses, 4-C formula Pneumatic quick connectors.
Specific implementation mode
The utility model is further illustrated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, protecting tool, including sequentially connected stainless steel argon filling for small-bore high alloy steel pipe internal argon-filling
Mouth 1, gas flow regulating valve 2, silica gel hose 3 and C formulas Pneumatic quick connector 4.
Stainless steel argon filling mouth 1 is the stainless-steel thin-wall pipe of diameter 6mm, and one end is flat, and is drilled with the venthole 3 of 2mm,
The other end is welded with gas flow regulating valve 2.Gas flow regulating valve 2 be using in waste and old cutting torch acetylene regulating valve repacking and
At ontology is copper casting.Gas flow regulating valve 2 is connect with silica gel hose 3, and silica gel hose 3 is length 600mm, diameter
14mm, the resistance to electric arc of wall thickness 2mm, high temperature resistant silica gel product.Silica gel hose 3 is connect with C formulas Pneumatic quick connector 4, and C formulas are pneumatically fast
Quick coupling 4 is made of SH20 females and PH20 male connectors, and PH20 male connectors tail portion connects trachea.Entire combination is at a set of osculum in this way
Diameter argon-filled protection tool.Stainless steel argon filling mouth 1 need to be only put into when use inside pipeline alignment clearance and place firm, opening gas
Body flow control valve 2 adjusts argon flow amount until reaching welding requirements.
The operation principle of the utility model：
As shown in Fig. 2, when welding small-bore high alloy pipeline, the solvable paper of pipeline inner utilization is blocked first, is formed
Gas chamber, gas chamber both ends are generally apart from Weld pipe mill about 200mm or so, after gas chamber is carried out, can butt welding mouth be grouped.It will originally fill
Argon protects the flat stainless steel argon filling mouth in tool one end to be inserted into plenum interior from alignment clearance, and coats asbestos in pipeline-weld position
Cloth or solvable adhesive tape, make commissure inner cavity of pipe become a closing inner chamber, and other end C formula quick couplings connect gas port access argon gas.
Until gas chamber can normally complete welding job after being completely filled with argon gas.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
