Description
Technical field
The utility model relates to gas utensil, particularly relates to a kind of gas utensil connecting tube.
Background technique
Corrugated stainless steel tubing because of its long service life, easily install, the feature such as attractive in appearance, corrosion-resistant, be widely used in every profession and trade.In family expenses gas burning system, the metal bellows characteristic more reliable, more safer than the flexible pipe of other material have also been obtained to be approved widely.Therefore, metal bellows uses more and more general in the connection of household gas apparatus and source of the gas, and some place has forced to use.But under the environment that this oil smoke in Chinese style kitchen is heavier, oil smoke has larger adverse effect the working life to corrugated stainless steel tubing.Therefore, need coated one deck protective material again at bellows outer surface, to improve bellows working life, reduce security risk.
As shown in Figure 1, existing gas utensil connecting tube comprises corrugated stainless steel tubing 1, and the outer surface of corrugated stainless steel tubing has clad 2, and clad 2 appearance surface cover detains ring 4, and the two ends of bellows are welded with welded joint 3, and welded joint 3 is connected with kink nut 5.Method for coating adopts the outer surface directly clad being set to bellows, or with extruder plastic materials to be extruded and to be coated on bellows outer surface, clad 2 surface is flat, and coated complete bellows can produce fold when bending, bending radius strengthens, and adds difficulty to installation; Further, the material of clad is generally PVC, and easily aging, temperature tolerance is poor.Above-mentioned gas utensil connecting tube assembling process comprises the steps: 1, is first welded with corrugated stainless steel tubing by the welded joint of one end, 2, corrugated stainless steel tubing is penetrated external coating, and detain ring by 2 and be all enclosed within external coating, 3, ring and external coating strip will be detained to the one end of having welded, temporarily fixing, 4, the soldered splice of the other end is welded with corrugated stainless steel tubing, 5, by external coating and detain ring restore to the original state, 6, make to detain latch closure and give as security distortion, for fixing external coating, visible, this assembling process is more complicated.
Summary of the invention
In order to the cover surface of the bellows outer surface solving existing gas utensil connecting tube is flat, coated complete bellows can produce fold when bending, bending radius strengthens, the problem of difficulty is added to installation, the invention provides a kind of gas utensil connecting tube, for household gas apparatus, comprise gas cooker, water heater etc.
In order to solve the problems of the technologies described above, the present invention adopts following technical proposals:
The invention provides a kind of gas utensil connecting tube, described gas utensil connecting tube comprises corrugated stainless steel tubing, corrugated stainless steel tubing outer cladding heat-shrink tube, the internal surface of heat-shrink tube and the intimate of corrugated stainless steel tubing fit together, the two ends of described corrugated stainless steel tubing are welded with welded joint, and on described welded joint, cover has nut.
Outer covering layer can not be made when above-mentioned connecting tube bends to produce fold, and heat-shrink tube has the function of softness, fire-retardant, insulation corrosion protection, the more general materials'use life-span is longer, and Security is higher.
Above-mentioned heat-shrink tube, also referred to as thermal contraction casing tube or heat-shrinkable tube, is a kind of insulation protection being applied to various wire harness, solder joint, inductance, has the thermal contraction casing tube of high-temperature shrinkage, soft fire-retardant, insulation corrosion protection function.The heat-shrink tube of the specification of answering Selection radio outside diameter of bel larger during use, is inserted in the outer surface of corrugated stainless steel tubing at normal temperatures, is heated to more than 125 DEG C, makes together with heat-shrink tube fits tightly with corrugated stainless steel tubing.
Above-mentioned gas utensil connecting tube, for household gas apparatus, comprises gas cooker, water heater etc.
Further, the thickness of described heat-shrink tube is 0.3 ~ 0.5mm.
Further, the material of described heat-shrink tube is polyethylene (PE).
Further, the outer surface of described heat-shrink tube is bellows-shaped.
Further, described heat-shrink tube outer surface does not detain ring.
Further, the two ends of described heat-shrink tube are coated on the outer surface of welded joint.Like this, welded joint also receives the protection of heat-shrink tube.
Further, the outer surface of described welded joint has at least 1/2nd to be coated in heat-shrink tube.
Further, the outer surface of described welded joint has at least 2/3rds to be coated in heat-shrink tube.
Further, described nut is kink nut.
Further, described heat-shrink tube is coated on the outer surface of corrugated stainless steel tubing and welded joint.
The preparation process of above-mentioned gas utensil connecting tube is as follows:
1, first welded joint and corrugated stainless steel tubing are welded together,
2, the corrugated stainless steel tubing after welding is penetrated in heat-shrink tube,
3, the corrugated stainless steel tubing packaging heat-shrink tube is put into vessel in heating, heat-shrink tube is shunk.
Compared with existing gas utensil connecting tube, gas utensil connecting tube provided by the invention is more soft, reduces installation difficulty.Further, the longer service life of gas utensil connecting tube provided by the invention, Security is higher, has better economic benefit and good social benefit.Further, gas utensil connecting tube provided by the invention does not re-use detains ring, decreases component, preparation process decreases process step, and, existing bellows when penetrating external coating, because clad internal diameter is only slightly large than outside diameter of bel, and external coating and ring strip to be detained to the one end of having welded when welding one, trouble is required great effort again, and after adopting structure provided by the invention, the internal diameter of heat-shrink tube is more more greatly than the external diameter of bellows, penetrate easily, therefore also reduce labor intensity.
