Technical field
The present invention relates to a kind of pipe connecting structure, especially a kind of two high pressure resistant large deflection macro-axis with the tubing of axis amount of deflection that can connect move earthquake-resistant tubing flexible connecting structure.
Background technique
Pipeline, when production, is considered the convenient requirement of the technological requirement of processing, transport, generally have the restriction of length, and the length of pipe laying is unrestricted, and therefore, pipeline all needs to connect when laying uses.
It is all that pipe joint connects that existing pipeline connects generally, and pipe joint generally adopts cylindrical shape pipeline section, and two ends connect the end of two pipelines respectively, or the end of inserting two pipelines is fixed.Also have a kind of be pipeline when production and processing, be directly made into one end expand structure, make one end of another pipeline can be inserted into the end internal fixtion of expansion.
It is all be positioned in a pipe alley of having constructed that above-mentioned pipeline connects generally, but the factor such as the uneven settlement often due to soil layer bottom pipe alley, the motion change of the earth's crust, earthquake causes it laterally, to be longitudinally subjected to displacement, thus make the central axis of adjacent channel that dislocation and deflection occur, always an angle is there is between pipeline, and this can meet the needs of topography variation when just requiring that pipeline connects, meet facility and sealing that pipeline connects again.
Existing pipeline connection mostly adopts fixing mode to connect, and this mode is when the region that geological condition is poor uses, and be easily subject to geology variation and produce pipe connection portion position seepage, fracture appears in severe patient.
Consider based on said circumstances, need the pipe connecting structure that a kind of amount of deflection is large, anti-seismic performance good, two way sealed is good, easy to connect badly.
Summary of the invention
The object of the invention is to provide a kind of high pressure resistant large deflection macro-axis and moves earthquake-resistant tubing flexible connecting structure, the mode be nested with is adopted to connect the relative end of two pipelines, Spielpassung when being nested with, easy to connect, the position contacted with pipeline outer wall is provided with two-way seal, good airproof performance.
The invention solves during existing pipeline connects and require that the axis of two pipelines keeps coaxial, the defect of landform restriction is easily placed by pipeline, a kind of high pressure resistant large deflection macro-axis is provided to move earthquake-resistant tubing flexible connecting structure, adopt lips and teeth rubber ring Spielpassung, the axis energy adaptation to the ground change of two pipelines.
This invention also solves the connection of existing pipeline and belong to fixed connection, responsive to vibrations, easily by the defect of geology variable effect, a kind of high pressure resistant large deflection macro-axis is provided to move earthquake-resistant tubing flexible connecting structure, and adopt Spielpassung between pipeline, gap length is adjustable by the design of rubber ring, and gap length determines the amount of deflection size of connection, certain vibrations can be born, adapt to geology change.
This invention also solves existing pipeline and connect the defect not allowing pipeline axial displacement, a kind of high pressure resistant large deflection macro-axis is provided to move earthquake-resistant tubing flexible connecting structure, multiple-sealed parts are set in connecting body, certain intervals is kept between every one sealed member, after pipeline generation axial displacement can be ensured, continue to both sides the validity ensureing sealed member by connecting body center step by step, thus keep the two-way seal request closing water.
