Abstract
A copying pipe fitting used for quick connection and repair of a pipeline consists of a high-strength fiber tape 1, a flexible seal tape 2 and a tape tightening device 3. The flexible seal tape 2 is used for sealing; the high-strength fiber tape 1 is used for bearing working pressure and restraining the deformation of the flexible seal tape 2; the tape tightening device 3 is used for tightening the high-strength fiber tape 1 and compressing the seal material. Limit rings can be additionally arranged on the two sides of the high-strength fiber tape for limiting the movement of the seal tape and preventing the seal tape from falling off; and a locking ring also can be arranged on the copying pipe fitting to prevent a pipe workpiece 5 from sliding off from the pipe fitting. The contour pipe fitting is used for the connection and repair of an equal-diameter pipeline; in addition, the copying pipe fitting also can be fabricated into different shapes for the connection and repair of pipe fittings, such as a reducing pipe, a tee joint and an elbow. The copying pipe fitting is a bidirectional flexible pipe fitting, effectively reduces the adverse effect on the pipeline caused by temperature change, uneven foundation subsiding and external pressure and the like, has low regularity requirement on the section of the pipeline and low requirement on construction environment and ensures the construction to be quick and convenient.
Description
Technical field
The utility model relates to a kind of profiling pipe fitting, is used for the quick connection and the reparation of pipeline.
Background technique
Pipes connecting method at present commonly used has: be welded to connect, flange connects, socket joint connects and the flexible pipe card connection.
Be welded to connect that there are the following problems: since tubing cross-sectional dimension irregularity, tubing location difficulty, the welding difficulty; The metal pipe weld is perishable, and is difficult to do preservative treatment.
There are the following problems in the flange connection: sealing gasket is difficult to fix; The bolt of required installation is more; The bolt hole that is connected is difficult to centering, the bolt penetration hole difficulty; It is fastening fully be difficult to by installing space restriction bolt, and it is fastening to be difficult to symmetry, influences the joint bearing capacity; Sealing gasket is easy to dislocation, and the tubing that is connected also is easy to dislocation, has strengthened the pressure loss of pipeline.
Be welded to connect to be connected and subdue the moment of flexure that produces because of pipeline ground generation uneven settlement, easily cause pipeline break with flange.
There are the following problems in the socket joint connection: the tubing that is connected needs basic centering, has so strengthened the pipeline construction difficulty; Influenced by tubing cross-sectional dimension irregularity, the joint bearing capacity is not high; Improve bearing capacity as desire, need install clamp flange in addition additional, strengthened investment, increased difficulty of construction.
There are the following problems for the flexible pipe card connection: because of tubing cross-sectional dimension irregularity, need join the standard pipe end and cooperate with pipe clamp, in advance pipe end is welded on the tubing, weld is perishable, need do preservative treatment.This method investment is big, and difficulty of construction is also big.
When pipeline ground generation uneven settlement or when bearing big external pressure, socket joint connect and the Sealing pressurized of flexible pipe card connection joint inhomogeneous, reduced bearing capacity, in the time of seriously, can cause Sealing to come off, pipeline leaks in a large number.
Pipe repairing method commonly used at present has: steel pipe adopts welding method more; Plastic tube adopts replacing tubing more; Glass Steel Tube adopts winding method more.These restorative procedures are had relatively high expectations to construction environment.In order to guarantee repairing quality, need spend the plenty of time during construction and expense is created corresponding environment.
The product that is used for pipeline rehabilitation on the market is still rare.In recent years, the compound reparation pipe clamp of a kind of steel rubber appears on the domestic and international market.Such pipe clamp is less demanding to construction environment, but the cross-section of pipeline regularity is had relatively high expectations.When piping failure place cross section irregularity or because of external pressure moderate finite deformation taking place, mend easily leaks.
Summary of the invention
The purpose of this utility model is to provide a kind of profiling pipe fitting that tubing connects fast, repairs that is used for.This profiling pipe fitting has following advantage:
1,, connects or repair fast and simple to the basic no requirement (NR) of construction environment;
2, lower to the requirement of tubing cross section regularity, the tubing of connection or repair place does not have significant depressions or projection, can use this pipe fitting;
3, can subdue the influence of pipeline uneven settlement of foundation, the influence of pipeline external pressure and influence of temperature change effectively.
The utility model profiling pipe fitting, it is characterized in that: comprise high-intensity fiber band, flexible sealing band and belt tightener, its shape can change along with the change in shape of the pipeline that is coated, the hoop shape is similar to the cross-section of pipeline shape, so, lower to the requirement of tubing cross section regularity, and subdued the influence of pipeline external pressure effectively; Longitudinal rigidity is low for flexibly connecting, and has subdued uneven settlement of foundation influence and influence of temperature change effectively.
The utility model periphery is the high-intensity fiber band, and the inboard is the flexible sealing band, and the two ends of high-intensity fiber band are belt tightener, and dual-side is provided with limited ring.Because high-intensity fiber band and sealing strip have ductility, can curl easily, stretch, it is very easy to construct.During the locking belt tightener, the high-intensity fiber band is compressed in its inboard flexible sealing band, and flexible sealing takes up seal action; The high-intensity fiber band is born working pressure, and the distortion of constraint flexible sealing band.
The flexible sealing band can be bonded together with the high-intensity fiber band.
As further improvement, can select corresponding high fiber strength strains and flexible sealing material for use according to factors such as line transportation medium, working pressure and operating temperatures.
As further improvement, can select the flexible sealing band of respective shapes for use according to factors such as product purpose and working pressures, determine corresponding sealing configuration.
As further improvement, can install additional and tighten annex as required, prevent tubing slippage from pipe fitting, also can install positioning attachment additional, prevent that horizontal the moving of sealing material from coming off.
As further improvement, can be made into different shapes, be used for the connection and the repairing of pipe fittings such as reducer, threeway, elbow.
The utility model profiling pipe fitting has fully absorbed the advantage of existing pipeline connection, recovery technique, and its outstanding feature is a bidirectional flexible, has subdued the adverse effect that various factors brings to pipeline effectively.
The utility model profiling pipe fitting can be used for the connection and the reparation of the tubing of various materials such as metal pipe, plastic tube, frp pipe, steel-plastic composite pipe.
