Abstract
The utility model relates to a compensator, particularly a full sealed metal corrugated compensator. The utility model comprises an outer bushing, a free end pipe and a corrugated pipe, wherein a gap is arranged between an end flange of the outer bushing and the free end pipe which is sheathed with a sealing device, and the sealing device can block the gap and can be fastened by fasteners. The utility model has the superiority that the full sealed metal corrugated compensator has the advantage of good tightness performance, the utility model not only can efficiently prevent groundwater or surface water from entering the compensator via the gap of the free end pipe so as to corrode the stainless steel corrugated pipe. Even the corrugated pipe is broken, the medium in the pipe network can not lead from the gap of the free end pipe, so the compensator can normally work, and the utility model can reduce economic loss caused by compensator leakage.
Description
The utility model relates to a kind of compensation device, particularly a kind of hermetically sealed metal corrugation compensator.
Current the most frequently used in heat distribution pipe network be axial directly buried compensation device.The movable end pipe of this product one end and the end flange of outer sleeve leave certain clearance, to guarantee that the movable end pipe freely stretches or compression under the state that pipe network expands with heat and contract with cold, when underground water or face of land immersion pipe network, because the existence of this gap, contain the underground water of chlorion or surface water and enter compensator internal corrosion corrugated stainless steel tubing from the gap of movable end pipe, can be in a short period of time with the bellows corrosion failure, make whole compensator occur leaking, ineffective, cause great economic loss for whole pipe network, this is there is wretched insufficiency in this product on technology and structure place.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of underground water or surface water of preventing to enter the hermetically sealed metal corrugation compensator of compensator inside.
As above design, the technical solution of the utility model is:
A kind of hermetically sealed metal corrugation compensator, comprise between the end flange of outer sleeve, movable end pipe and bellows, outer sleeve and the movable end pipe gappedly, it is characterized in that, be with seal arrangement on the movable end pipe, the sealing device can block above-mentioned gap, and fastening in addition with fastening piece.
The seal ring that described seal arrangement is made with the Expanded graphite ring.
Described seal arrangement clamps by the flange circle that the pressure ring and that is enclosed within on the movable end pipe is fixed on the outer sleeve, and is screwed.
Superiority of the present utility model is:
1, good seal performance, can not only prevent effectively that underground water or surface water from entering compensator inside by the gap of movable end pipe, the corrosion corrugated stainless steel tubing, and both just when bellows bursts, medium in the pipe network can not leak from the movable end ligament yet, the compensator proper functioning, 2, can reduce widely because of compensator and leak the economic loss caused.
The utility model will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a sectional drawing of the present utility model.
Embodiment:
A kind of hermetically sealed metal corrugation compensator comprises between the end flange 4 of outer sleeve 1, movable end pipe 2 and bellows 3, outer sleeve and the movable end pipe gappedly 5, it is characterized in that the seal ring 6 that the useful Expanded graphite ring of cover is made on the movable end pipe.The sealing circle can block above-mentioned gap, and clamps with being enclosed within the flange circle 8 that pressure ring 7 and on the movable end pipe is fixed on the outer sleeve, and fixes with screw 9.
Claims (3)
1, a kind of hermetically sealed metal corrugation compensator, comprise between the end flange of outer sleeve, movable end pipe and bellows, outer sleeve and the movable end pipe gappedly, it is characterized in that, be with seal arrangement on the movable end pipe, the sealing device can block above-mentioned gap, and fastening in addition with fastening piece.
2, hermetically sealed metal corrugation compensator according to claim 1 is characterized in that, the seal ring that described seal arrangement is made with the Expanded graphite ring.
3, hermetically sealed metal corrugation compensator according to claim 1 is characterized in that, described seal arrangement clamps by the flange circle that the pressure ring and that is enclosed within on the movable end pipe is fixed on the outer sleeve, and is screwed.
