Description
Technical field
The present invention relates to feedwater and draining field, specifically a kind of pipe jointer.
Background technique
Pressure-proof composite pipeline is the novel tube that the one of in recent years rising is composited by high-strength material (normally steel wire) and plastics, and in work progress, the general mode of docking melting welding or electric melting sleeve that adopts is connected and fixed.
Docking melting welding mode can only by (and cannot carry out melting welding to ducted high-strength material) welded together for the plastic melting of pipeline joint, the axial load of pipeline joint can be reduced like this, thus reduce bearing capacity and the loaded capability (joint becomes the weak link in pipe-line system) of pipeline, in use easily burst;
Electric melting sleeve mode expands the sectional area of this position by an electric melting sleeve on pipeline joint overcoat also welding, thus the load carrying capacity of raising pipeline is to avoid in docking melting welding because sectional area reduces the adverse effect brought; But its shortcoming be pipeline and electric melting sleeve entirely by reinforcing material is made, each other cannot welding completely between plastic layer during welding, cause loaded capability lower, and adopt the cost of electric melting sleeve higher, construction requirement is higher.
Summary of the invention
The object of the invention is to overcome the deficiency in above-mentioned background technology, provide a kind of pipe jointer, this connector should have good seal performance, easy construction, cost feature lower and applied widely;
Technological scheme of the present invention is: a kind of pipe jointer, is characterized in that: this connector comprises the coupling sleeve be set on two pipeline joint outer peripheral surfaces, be arranged on two flanges at coupling sleeve two ends, be positioned at two O-ring seals between coupling sleeve both sides end face and flange respectively and lock flange and make O-ring seal produce the locking mechanism of seal action;
Described locking mechanism comprises the some positioning holes be formed on flange, passes through some screw mandrels of two flange positioning holes, is arranged on screw mandrel two ends to produce the nut of axial tension to two flanges;
Described flange is shaped with for the taper locating face of crush seal cushion rubber, axially extended cylinder limit and outstanding to the outer diameter and be shaped with the outer of some positioning holes.
The both sides end face of described coupling sleeve is shaped with the inner conical surface for oppressing O-ring seal.
The both sides of described O-ring seal are shaped with first conical surface coordinated with taper locating face and second conical surface coordinated with inner conical surface respectively.
The invention has the beneficial effects as follows:
1, sealed by the cooperation of flange, O-ring seal and locking mechanism, good sealing effect can be ensured;
2, can free-extension vertically when pipeline expands with heat and contract with cold, avoid the shortcoming that pipeline in prior art needs to bear axial load, improve the Security of pipeline;
3, install, dismantle and keep in repair all more for convenience, cost lower (being about 40% of prior art);
4, can be used for the installation of sizes tubing, Applicable scope is comparatively large, also can be used for repairing broken pipe simultaneously.

Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the present invention is not limited to following examples.
As shown in Figure 1, a kind of pipe jointer, comprises coupling sleeve 2, two flanges 3, two O-ring seals 4 and locking mechanisms;
Described coupling sleeve is sleeved on the joint (in figure shown in B) of pipeline 1, and the both sides end face of coupling sleeve is inner conical surface 21; The material of coupling sleeve and existing pressure-proof composite pipeline roughly the same, generally can adopt high-strength material and plastics compound to make.
Described flange sleeve to be contained on pipeline and to be located at coupling sleeve two ends, flange is shaped with for the taper locating face 31 of crush seal cushion rubber, cylinder limit 32 and outer 33; The bus angle of described taper locating face and pipeline outer peripheral surface is acute angle (shown in Fig. 2), usually can determine at 45-80 degree.Described cylinder limit extends and can locate the outer peripheral surface (coupling sleeve can insert in a limit) of O-ring seal on the axial direction of pipeline; Described outer extends on the external diameter direction of pipeline, and outer is shaped with some positioning holes 34; The axis being parallel of positioning hole is in the axis of pipeline, and quantity is generally 6-18 (quantity of positioning hole shown in Fig. 4 is 12); Flange material can be steel or the material identical with coupling sleeve (high-strength material and plastics are composited).
Described O-ring seal is positioned between coupling sleeve both sides end face and flange, and the both sides of O-ring seal are shaped with first conical surface 41 coordinated with locating face and second conical surface 42 coordinated with inner conical surface respectively; O-ring seal material recommends to adopt rubber or silica gel.
Described locking mechanism makes O-ring seal produce seal action by locking flange, comprises the positioning hole 34 be formed on flange, passes through the screw mandrel 51 (Flange joint of both sides gets up and the quantity Matching of the quantity of screw mandrel and positioning hole by screw mandrel) of two flange positioning holes, is arranged on screw mandrel two ends to produce the nut 52 (nut is separately positioned on the outside of two flanges) of axial tension to two flanges; When fastening nut, two flanges are constantly drawn close and promote O-ring seal gradually near the end face of coupling sleeve on the axial direction of pipeline, to elastic strain be there is in O-ring seal under the extruding of flange, thus be tightly fitted on the outer wall of pipeline and the inner conical surface of coupling sleeve, the space blocked between pipeline outer peripheral surface and coupling sleeve inner peripheral surface is formed and seals; The deformation size of described O-ring seal depends on the external diameter of nut applied pressure and pipeline.
Installation method of the present invention is:
1, flange and O-ring seal are put pipeline successively, O-ring seal needs to push in the locating face of flange;
2, the pipeline overlapping upper flange and O-ring seal to be pushed from two ends respectively in coupling sleeve (the pushing the half that distance is about coupling sleeve length of each pipeline);
3, screw mandrel is each passed through in the positioning hole of two flanges, then loads onto nut and tighten, make O-ring seal under the effect of the pressure resiliently deformable occur, play seal action; The present invention can be arranged on the pipeline of other sizes the external diameter of the pipeline (can bigger or also can be smaller), and O-ring seal also can ensure same sealing effect; When expanding with heat and contract with cold, pipeline can free-extension in the axial direction, thus improves Security.
