Background
The moment when the motor of the compressor is started and stopped enables the compressor to swing towards two sides, and long-time running can cause the pipeline to shake and break or have cracks. Therefore, many refrigeration compressors now have shock tubes installed. The existing corrugated shock absorber pipe structure generally comprises a corrugated pipe, a braided pipe, a pressing ring, a joint and other parts, wherein the corrugated pipe, the braided pipe and the pressing ring are mainly adopted in the existing connecting structure, the mutual airtight connection is realized by the technical structure of spot welding inside and outside the joint, the structure is provided with two welding rings inside and outside, namely two leakage points are provided, and the actual use function can be realized only by welding a connecting pipe on the joint again by the connecting structure.
How to reduce the leakage point of the shock absorbing tube and the anti-rust performance of the pipe connecting part are the subjects studied by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model provides a stainless steel shock tube with few leakage points and long service life.
A stainless steel shock-absorbing tube comprises a corrugated tube, wherein a braided tube is sleeved on the periphery of the corrugated tube, a joint is welded at the outer end parts of the corrugated tube and the braided tube, a step-shaped inner hole is formed in the inner side of the joint, and a step-shaped ring is arranged on the outer side of the joint; the inner wall surface of the step-shaped inner hole is in a shape of being jointed and welded with the pipe orifice of the corrugated pipe; the outer wall of the step-shaped circular ring is attached and connected with the braided tube, and the outer wall of the braided tube is pressed and connected with the pressure ring; the braided tube, the pressing ring and the step-shaped circular ring are connected in a welding mode, the top of the pressing ring is a solder accumulation surface, and the solder is welded in a linear annular mode to form the braided tube, the pressing ring and the joint. This kind of stainless steel shock absorber pipe adopts linear solder welding to weave pipe, clamping ring and step form ring, forms a possible leakage point, and the inboard adopts the planar laminating welding bellows mouth of pipe of step form inner wall face form to form planar welding face and just do not have linear welding point yet, and whole connection process has the leakage point in an outside, greatly reduced the leakage risk, prolonged the life of ripple shock absorber pipe.
The connector is made of stainless steel materials, the outer end face of the step-shaped inner hole is closer to the outer end face of the connector relative to the outer end face of the step-shaped ring, and the end face structures at two different positions are more beneficial to connecting other pipelines by the connector, so that the length of the other pipelines penetrating into the connector is reduced.
The bottom of step form hole be equipped with the chamfer, this kind of chamfer structure is favorable to the bellows mouth of pipe to insert step form hole, improves the laminating leakproofness between bellows mouth of pipe and the step form hole.
The outer diameter of the step-shaped ring is larger than that of the corrugated pipe, so that the braided pipe forms two different pipe diameters on the outer sides of the corrugated pipe and the step-shaped ring, the braided pipe is enabled to be more tightly coated on the corrugated pipe, and air leakage is prevented.
The corrugated pipe orifice is welded in the surface furnace brazing or argon arc welding mode on the inner wall of the step-shaped inner hole, and the welding effect is improved.
Bellows, weave pipe, joint, clamping ring be stainless steel material, prevent that whole ripple shock absorber pipe from appearing the problem of rustting.
The utility model adopts the inner wall surface shape of the step-shaped inner hole to joint and weld the pipe orifice of the corrugated pipe to form a surface-shaped welding surface, so that no linear welding point exists, only one leakage point is arranged at the outer side in the whole connecting process, the leakage risk is greatly reduced, and the service life of the corrugated shock absorbing pipe is prolonged.
Drawings
The utility model is further described below with reference to the accompanying drawings:
FIG. 1 is a schematic cross-sectional view of a stainless steel shock tube according to the present invention.
Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Please refer to fig. 1, which illustrates a stainless steel shock absorbing tube, comprising a corrugated tube 6, a braided tube 7 sleeved on the periphery of the corrugated tube 6, a joint 4 welded to the outer end of the corrugated tube 6 and the braided tube 7, a step-shaped inner hole 3 inside the joint 4, and a step-shaped ring 1 outside the joint, i.e. the joint 4 forms two convex ring structures on the inner and outer sides, the ring structure with thick wall is more heat-resistant and is beneficial to the following high-temperature welding, and the wall of the joint 4 can be relatively thinned to save the manufacturing cost.
In order to reduce the welding leakage point, the bottom of the step-shaped inner hole 3 is provided with a chamfer 9 for guiding the corrugated pipe opening to be attached and connected with the step-shaped inner hole 3, and the corrugated pipe opening is welded in a brazing or argon arc welding mode in the step-shaped inner hole 3 inner wall surface furnace to form a welding structure of a surface area, so that the leakage risk of a medium is avoided.
