Abstract
The utility model relates to a direct built-in system pipe compensator; the design principle of a plunger piston type cylinder is adopted. The utility model is characterized in that one end of a mobile connecting pipe (a plunger piston) is connected with a corrugated pipe arranged in a cylinder body; the mobile connecting pipe and a hole of a cylinder cap are in slide fit; an interstice between the mobile connecting pipe and the hole of the cylinder cap is sealed by a sealing ring; a protective sleeve is arranged on the exposed surface of the mobile connecting pipe; the outer layer pf the mobile connecting pipe is provided with a supporting steel pipe; the bottom of the cylinder is provided with a central circular hole; a fixed connecting pipe is arranged on the outer end surface of the cylinder; the inner end surface of the cylinder is connected with the corrugated pipe. The compensator can be made into a symmetrical structure and the form of connecting pipes with bidirectional movement. The compensator has the advantages of simple structure, compact structure, double-layer sealing, convenient construction and operational safety and can be directly embedded underground; the utility model can also shorten the construction period and decrease the cost.
Description
The utility model belongs to pipe coupling.
At present, Japan corrugated stainless steel tubing Co., Ltd. makes the bellows that group company produces according to the patent No. 91222106.2 according to NESS へ " mouth-ス " standard STYLENa3 LUOW and Shenyang bellows, the STYLENa3LUOW bellows can not directly be imbedded underground use, though patent 91222106.2 bellowss can be applicable to balanced directly buried installation, the bellows expansion joint place need establish an inspection shaft or darkroom.The engineering work load that this has just increased construction prolongs the construction time, has increased operating expenses.Sometimes retain rainwater in the inspection shaft, underground water will corrode expansion joint, also waste energy simultaneously.
The utility model is at the problem of above-mentioned existence; designed a kind of can be with the direct buried new structure of compensator (stainless steel expansion joint member); its design principle is; adopt hydraulic plunger formula cylinder structure principle; bellows is placed in the cylinder; one end is fixed on the cylinder bottom; cylinder bottom has hole, garden, center and affixed adapter; the other end and mobile adapter affixed (hollow plunger rod); move the adapter exposed parts protecting jacket is housed; constitute double-layer seal, prevent from the protecting jacket pressure ring when burying ground and guarantee to move to take over to move axially, a supporting steel pipe is installed in the protecting jacket outside; steel pipe is fixed on the cylinder cap end face with flange; after cylinder body two pipe nipples and piping erection are good, can do thermal insulation layer at cylinder body and outer surface of steel tube, directly imbed underground.According to above-mentioned design principle, compensator can be designed to symplex structure, places cylinder body middle shared cylinder bottom, and two-way mobile adapter so just can realize bidirectional compensating.
This directly buried type compensator can directly be imbedded undergroundly, and easy construction, duration be short, install rapidly, operating expenses is low.There is not exposed pipeline, good heat insulation, energy saving.Simple in structure, double-layer seal, safe and reliable.
Carry out the detail explanation with regard to the unidirectional mobile adapter of the utility model and in conjunction with an embodiment of two-way mobile adapter below.
Fig. 1 is that structural representation is axially partly cutd open in unidirectional mobile adapter.
Fig. 2 is that structural representation is axially partly cutd open in two-way mobile adapter.
In Fig. 1; fixing take over ［ 1 ］ is installed on the cylinder bottom ［ 2 ］ in hole, garden, band center; cylinder body ［ 4 ］ one ends that bleed valve ［ 3 ］ is housed connect with cylinder bottom ［ 2 ］; the other end is situated between with lid ［ 7 ］ by flange and helps bolt ［ 8 ］ to connect; in Fig. 2; place cylinder body ［ 4 ］ middle shared the cylinder bottom ［ 2 ］ in band hole, garden, center; respectively there is one to move adapter ［ 14 ］ at the two ends of cylinder body ［ 4 ］; at Fig. 1; among Fig. 2; bellows ［ 5 ］ places in the cylinder body ［ 4 ］; one end connects with cylinder bottom ［ 2 ］; the other end connects with mobile take over ［ 14 ］; move and take over ［ 14 ］ and cylinder cap ［ 7 ］ endoporus sliding fit; its matching gap seals with seal ring ［ 9 ］; move and take over ［ 14 ］ exposed surface installation protecting jacket ［ 11 ］; protecting jacket ［ 11 ］ one ends connect with cylinder cap ［ 7 ］ end face by screw ［ 10 ］; the other end is fixed in to move by pipe collar ［ 12 ］ and takes on ［ 14 ］; protecting jacket ［ 11 ］ outside mounting support steel pipe ［ 13 ］; steel pipe ［ 13 ］ one ends connect with cylinder cap ［ 7 ］ end face with flange; water conservancy diversion cover ［ 6 ］ places in the bellows ［ 5 ］, and an end is fixed in fixing the adapter on ［ 1 ］.
The utility model, simple in structure, compact, in light weight, be easy to installation and processing, good airproof performance can directly be imbedded underground, safe in utilization, and the duration is short, does not have exposed pipeline, insulation, energy saving.
