Background technique
As everyone knows, the Leakage of construction machinery hydraulic system is a difficult problem for puzzlement industry always, and wherein the leakage of oil of high pressure hose occupies the overwhelming majority, it is the link that in whole hydraulic system, reliability is the weakest, maintain and replace is frequent, not only increase the user cost of user, also befouling environment, serious may occur that body pull-off causes the malignant event of people's injures and deaths.
Hose assembly is generally divided into fastening-pressing type and detachable, Demountable because of sealing and difficult quality guarantee (" mechanical design handbook "-hydraulic transmission. chapter 8. hydraulic pressure auxiliary member and hydraulic power unit .20-677 page 1.2.5 hose coupling, Chemical Industry Press .2004 version separate edition. Cheng great Xian edits), therefore the engineering machinery high pressure hose of prior art all adopts fastening-pressing type structure substantially, as shown in Figure 1, utilize crimping equipment by joint core X, body G, hose proof T withholds and links together, hose proof and joint core arrange annular groove (withholding tooth), to strengthen withholding snap-in force thus improving anti-pulling-and-doffing performance energy tube wall.Although above technology comparative maturity, but still there is the following obvious deficiency being difficult to overcome: 1, complex manufacturing technology, withhold quality control difficulties: the amount of withholding is excessive is easy to damage body steel wire and glue-line, and joint core tube wall easily longitudinally subsides; The amount of withholding is too small affects sealing effect again, and uses the easy pull-off of middle tube body; 2, the latus rectum of joint core is less than pipe body drift diameter, and joint area exists throttling, and variable cross section place is easy to produce turbulent energy loss; 3, there is polygon effect in the place of withholding, and the radial compression amount of withholding position body one border is not equally distributed, and the position decrement being positioned at polygonal wedge angle is less than normal, and inboard wall of tube body is easy to produce gauffer herein, causes leakage of oil; 4, joint core, hose proof cannot reuse, and cause the wasting of resources, too increase the maintenance user cost of user.Due to above technical deficiency, cause engineering machinery that high pressure hose in use often occurs and withhold fault such as place's leakage of oil, body pull-off etc.For above Problems existing, have also been made a large amount of improvement in recent years, such as: for improving sealability, some roads seal ring being set at the position of withholding of joint core and withholding (the patent No.: 201210167200.7 in joint core with body; 201420600091.8); For improving anti-pull-off performance, improve the set-up mode (patent No.: 99248007.8 of annular groove (withholding tooth) in hose proof and joint core; 200520077228.7; 200620160181.5; 201120246152.1; 201120575790.8; 201220297887.1; 201220359891.6; 201220719076.6; 201320416406.9; 201320654065.9; 201320891514.1), or adopt the outer mode connecting steel wire joint core to be connected in outside with body, then increase the anti-pull-off safety curtain (patent No.: 201420464379.7) together; For avoiding joint to produce turbulent flow, joint core sets up the flow guide structure (patent No.: 201420548536.2).Above technology respectively never with aspect part improve the deficiencies in the prior art, but still fundamentally cannot thoroughly eliminate above defect, especially for engineering machinery, because its operating environment is severe, applying working condition is complicated, the reasons such as field maintenance inconvenience, higher requirement is had to the reliability index of high pressure hose, existing technology there is no the demand that method meets client completely, the high pressure hose product of a kind of high reliability of market in urgent need meets the operating mode needs of machine, to reduce field fault power time, meet project progress, reduce part replacement cost, reduce to reveal and pollute.
Summary of the invention
Existingly withholding hose assembly complex manufacturing technology, quality control difficulties to solve, withholding the problems such as position rate of fault is high, joint exists throttling and turbulent flow, joint core and hose proof cannot reuse, user cost is high, the invention provides a kind of novel pressure flexible pipe and connect component, fundamentally solving the deficiencies in the prior art.
The present invention realizes by the following technical solutions: a kind of novel pressure flexible pipe and connection component thereof, comprise taper joint, body, half cone lobe and lockup device.The stage casing of body is tubular shape, and two ends are stretch out along axis to expand the taper mouth of the uniform wall thickness formed.The center of taper joint is a through oil duct consistent with pipe body drift diameter, and one end of joint is taper, and the small end of taper outwardly, mates within the internal conical surface that the outer conical surface of taper is inserted in body taper mouth and with its conical surface and forms conical surface seal and coordinate; The other end of joint is that fastening structure can coordinate formation to be fastenedly connected with lockup device, hydraulic parts Y.Half cone lobe has the indent conical surface that a reference level M and a surface are 1/2 conical surface, the axis of this indent conical surface and initial bus and stop bus and be all positioned on reference level M.Half cone lobe must match use, make reference level M relatively during assembling and overlap, be assemblied in the outer conical surface of body taper mouth with reference level M for symmetry plane symmetry, ensure that the indent conical surface of two half cone lobes forms a complete internal conical surface in theory and mates to be formed with the outer conical surface of body taper mouth and coordinate.After lockup device and taper joint, hydraulic parts Y are fastened together, two half cone lobes are under the constraint of radial and axial both direction, the indent conical surface of two half cone lobes to be formed all the time in outer conical surface that a complete internal conical surface is pressed on body taper mouth and keeps correct cooperation, and meanwhile the internal conical surface of body taper mouth is then pressed in the outer conical surface of taper joint taper.After taper joint, body, half cone lobe and lockup device to be coaxially assembled together by above assembly relation and to ensure the fastening force that taper joint and lockup device reach suitable, the tube wall of body taper mouth is just subject to reasonably extruding and producing the resiliently deformable meeting seal request between the outer conical surface of taper joint and the indent conical surface of half cone lobe, thus reaches the object that the present invention is tightly connected.Lockup device to axially fasten power larger, the extruding force suffered by taper mouth tube wall be clamped between the outer conical surface of taper joint and the indent conical surface of half cone lobe is also larger, therefore sealing effect can be controlled easily by lockup device, thus avoids the generation of leakage.Within the rational regime of elastic deformation that tube wall can bear, fastening force is larger, and sealing effect is better, and the ability of opposing body pull-off is also stronger.In theory, the taper mouth of body is objectively also conducive to stoping body pull-off, when body is subject to axial tension, perpendicular to the trend of the oriented less sectional flow of the material on the cross section of axis on body taper mouth, and be limited between the outer conical surface of taper joint and the indent conical surface of half cone lobe due to the size in cross section, therefore large cross section will must reduce section area by larger extrusion-deformation by little cross section, thus make tube wall be subject to larger extruding, produce the ability of larger opposing pull-off, so, body taper mouth can draw tighter and tighter when bearing axial tension, the ability of automatic increase opposing pull-off, avoid the generation of pull-off phenomenon.
Compared with prior art, the invention has the beneficial effects as follows: what 1, eliminate prior art withholds place's leakage of oil, body pull-off phenomenon; 2, eliminate the variable cross section at pipe joint place, avoid the generation of throttling, turbulent flow, increase pipeline passing capacity simultaneously; 3, solve the problem that joint cannot reuse, economize on resources; 4, simplify manufacturing process, quality control becomes simple and reliable; 5, the annular groove occlusion body body that may cause of withholding avoiding prior art injures; 6, be beneficial to environmental protection, use safety, easy to maintenance, user cost is low.
