Abstract
A corrugated telescopic adjustor comprises two flanges and is characterized in that a stainless corrugated pipe is arranged between the two flanges; two guide flow cylinders are respectively arranged on the two flanges and tightly cling to the inner surface of the stainless corrugated pipe; the two guide flow cylinders are tightly spliced with each other; and the two guide flow cylinders are close to the ends of the flanges and two ends of the stainless corrugated pipes, and are respectively welded on the flanges. The adjustor has the advantages of cracking resistance, less possibility of leakage, long service life, no need of maintenance, simple installation and no need of preservative treatment. Furthermore, the adjustor can not only compensate the displacement in the axial direction with large compensation displacement, but also compensate the displacement generated by pipes in the radial and angular directions, without affecting the service life. The adjustor can improve the corrosion resistance.
Description
Technical field
The utility model belongs to a kind of tap water pipe line connection set, particularly a kind of ripple expansion and cotraction regulator.
Background technique
Existing expansion bend be by two ends be provided with the outer sleeve of flange, interpolation pipe and the gland that an end is provided with flange constitutes, the other end of described interpolation pipe is inserted in the outer sleeve and use rubber sealing, gland to be installed on the port of corresponding interpolation pipe insertion on the outer sleeve.Because outer sleeve is a cast iron quality, poor corrosion resistance is easy to crack, and working life is short, after use a period of time corrosion takes place, and causes increase leakage in sealing surface gap between the inner and outer pipe, repairs very loaded down with trivial details; Inconvenience is installed, and need does preservative treatment; In addition, it can only carry out nose balance to water pipeline, to water pipeline produce radially, angular displacement can not compensate.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of both can the compensating axial displacement and the compensate for displacement amount big, can also the compensation pipes generation radially reach angular displacement; Corrosion-resistant, cracking resistance, be difficult for leaking long service life; Non-maintaining, install simply, need not do antiseptic ripple expansion and cotraction regulator.
The utility model is achieved in that it has two flanges, its special way is: be provided with corrugated stainless steel tubing between two flanges, on two flanges, be close to the corrugated stainless steel tubing internal surface and be respectively equipped with guide shell, tightly peg graft between two guide shells, described guide shell is welded on the flange respectively near flange end and corrugated stainless steel tubing two ends.
Above-mentioned ripple expansion and cotraction regulator is provided with postive stop baffle in the outer rim of flange, by screw thread position-limited lever is installed between positive stop block facing each other.
Above-mentioned ripple expansion and cotraction regulator is positioned between two flanges and is respectively equipped with outer shield outside the corrugated stainless steel tubing, tightly peg graft between two outer shields, and outer shield welds near flange end and flange, to play protective action.
The utility model has the advantages that: owing to adopt corrugated stainless steel tubing, both can the compensating axial displacement and the compensate for displacement amount big, can also the compensation pipes generation radially reach angular displacement, and do not influence working life; By the protective action of guide shell, can improve the decay resistance of bellows, cracking resistance is difficult for leaking long service life; Non-maintaining, install simply, need not to do preservative treatment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure, this ripple expansion and cotraction regulator has two flanges 1, between two flanges 1, be provided with corrugated stainless steel tubing 2, on two flanges 1, be close to corrugated stainless steel tubing 1 internal surface and be respectively equipped with guide shell 3, between two flanges 1, be positioned at and be welded with outer shield 7 outside the corrugated stainless steel tubing 2 respectively, tightly peg graft between two guide shells 3 and between two outer shields 7, described guide shell 3 is welded on respectively on the flange 1 near flange 1 end and corrugated stainless steel tubing 2 two ends.Three of each flange 1 outer rim welding or or four uniform postive stop baffles 4, on postive stop baffle 4, position-limited lever 5 is installed by screw thread 6, position-limited lever 5 is installed the qualified back of bulge test at pipe network and is removed.
Claims (3)
