Abstract
The utility model relates to an improvement on a sealing structure formed by the connection of a metallic flexible pipe and a joint component, which belongs to the technical field of metallic flexible pipe. The metallic flexible pipe comprises the joint component and the pipe, wherein the joint component is composed of a joint, a screw nut screwed outside the joint, a pad ring, and a pad piece, wherein the pad ring and the pad piece is clamped on the joint and the end surface of the screw nut. The pipe is composed of a corrugated pipe and a net sleeve sheathed outside the corrugated pipe. The utility model has the improvement that the end of the corrugated pipe is a straight pipe which is formed by compression after the corrugated pipe is stretched into a shallow wave. The end of the straight pipe extends into the joint, and the outer circle is fixedly connected with a grooved ring. The inside of the grooved ring is provided with a buckling ring for pressing and fixing the end of the net sleeve in the grooved ring. The utility model effectively overcomes the disadvantages of easy leakage, short service life, low price ratio, high consumption, etc. in the prior art and has the obvious advantages of low cost, simple structure, convenient assembly, the overequalization of rigid sections and flexible sections, fatigue resistance, etc.
Description
Technical field
The utility model relates to a kind of structure of metal tube, and especially a kind of metallic hose (metal bellows) body is connected with adapter assembly, the improvement of sealing configuration, belongs to metallic hose (metal bellows) technical field.
Background technique
At present, a large amount of industrial practices prove, adopt adapter assembly and the welded metallic hose of body (containing net) under the influence of operating modes such as long-term flexural fatigue, fluid pulsation, vibrations, the welding part stress that is easy to because of rigid section---adapter assembly and compliant section---bellows, net is concentrated and to be caused breakage, the result causes metallic hose generation leakage phenomenon, and is especially all the more so in the application of pipeline pressure≤3.0MPa.
The basic reason that above problem occurs is derived from the character of Type of Welding metallic hose own.Bad phenomenon such as therefore metallic hose is under above-mentioned working condition, and working life is short, cost performance is low, loss is big are outstanding.
Summary of the invention
The purpose of this utility model is: at the problem that above prior art exists, provide a kind of non-welded metallic hose of simple in structure, cost economy, this metallic hose should overcome the easy leakage problem of weld.
In order to reach above purpose, non-welded structure metal tube of the present utility model comprises adapter assembly and body, described adapter assembly by joint, screw the nut outside joint and be clamped in joint and the gasket ring of nut end face and pad are formed, described body is made of bellows and the net that is enclosed within outside it, its improvements are: the end of described bellows is to be drawn into the straight tube that is pressed into behind the shallow ripple, the termination of described straight tube is stretched in the joint, cylindrical is connected grooved ring is housed, and is equipped with in the described grooved ring pressure holding of net termination is fixed on the ring of withholding in the grooved ring.
Like this, do the time spent when compliant section is subjected to external stress, stress can effectively disperse, and has therefore properly settled the easy leakage problem of weld that exists in the tired motion of welded structure metallic hose.In addition, owing to cancelled welding procedure, so the joint material can select carbon steel, brass, stainless steel etc. for use according to the working condition needs, flexible and convenient not only, and can effectively reduce cost.
In a word, the beneficial effects of the utility model are, not only effectively overcome shortcomings such as prior art is easily leaked, the life-span is short, cost performance is low, loss is big, and had remarkable advantages such as with low cost, simple in structure, easy to assembly, rigidity section and compliant section overbalance, endurance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
1. bellowss among the figure, 2. net is 3. withheld ring, 4. grooved ring, 5. gasket ring, 6. pad, 7. nut, 8. joint.
Embodiment
The non-welded structure metal tube of present embodiment as shown in Figure 1, after bellows 1 moulding, the end stretches and cuts off, make the corrugated pipe segment of normal waveform be drawn into shallow ripple, even the internal diameter of bellows becomes greatly, external diameter diminishes, the shallow ripple bellows that will stretch again is processed into straight tube, stretches in the joint 8, cylindrical is connected grooved ring 4 is housed, and is equipped with in the grooved ring 4 ring 3 is fixedly withheld in the grooved ring in net 2 terminations.Nut 7 screws outside joint 8, and gasket ring 5 and pad 6 that this nut and the clamping of joint opposing end faces seal promptly by joint 8, gasket ring 5 extruding pads 6, seal joint 8, pad 6, bellows 1 mutually.Nut 7 is made disjunctor cylindrical ring-type towards an end of bellows, be wrapped in grooved ring 4 and withhold the ring 3 outside.
In addition, after the required specifications of nuts of fit on, carry out sealing surface processing at last,, and, form sealing surface on the flat end face that is clamped between gasket ring 5 and the pad 6 of this wave pressure at the ripple that on the bellows straight length between gasket ring 5 and the pad 6, expands.
As required, can assemble the pad and the joint of unlike material, specification.Because nut, joint adopt mechanical mount, therefore, do the time spent when compliant section is subjected to external stress, stress can effectively disperse, thereby has solved the easy leakage problem of weld that exists in the tired motion of weld metal flexible pipe.
In a word, experiment showed, that the non-welded structure metal tube of present embodiment has solved the easy problem of leaking of weld of metallic hose, and simplify the structure, reduced cost.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
