Abstract
The utility model discloses a full rigid hard connecting pipe fitting for a thin wall metal pipeline, which is characterized in that the utility model comprises a nut with a long tail, a hollow threaded sleeve, and two pipes with flanging edge ends, wherein two sections of pipes with the flanging are respectively passes through the inside of the nut with a long tail and the hollow threaded sleeve and is screwed with the hollow threaded sleeve through the nut with a long tail to cause the two sections of pipes with the flanging to be fixedly connected in a sealing form. The utility model has the advantages of simple structure and convenient connection and uses the full rigid connection to thoroughly solve the problems of leakage and repair caused by aging in the connection mode of soft sealing materials. The utility model can improve the bearing pressure of a pipe joint and the poor shock resistant properties caused by loose pipeline.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, the hard connection pipe fitting of the full rigidity of particularly a kind of thin wall metal pipeline.
Background technique
The Placement that the metal thin-wall metallic conduit adopts does not at present all break away from software sealing materials such as rubber and plastics basically, and there is problem of aging in they.After aging the appearance, seepage will take place in the fluid by pipeline, so outside pipeline can only be exposed to, can not imbed underground and object in, bring a lot of inconvenience to installing and using; Pipeline junction is uneven simultaneously, and residue is many, can not be used for industries such as chemical industry, food, pharmacy and use; And can not bear high pressure in the pipe, can not carry highly pressurised liquid and gas.
The model utility content
Technical problem to be solved in the utility model, promptly the purpose of this utility model has provided the hard connection pipe fitting of the full rigidity of a kind of simple and reasonable, easy to connect thin wall metal pipeline.And be rigidly connected entirely and thoroughly solved with software sealing material Placement because of aging seepage and the maintenance problem that brings, improved pressure that pipe joint bears and pipeline greatly because of becoming flexible the shock resistance that causes.
The technical solution of the utility model realizes by following measure:
The hard connection pipe fitting of the full rigidity of a kind of thin wall metal pipeline, it is characterized in that: comprise the long-tail nut, hollow swivel nut, the body of termination flange, the body of two sections termination flange penetrates respectively in long-tail nut and the hollow swivel nut, be spirally connected by long-tail nut and hollow swivel nut, the body of two sections termination flange is fastened and connected.
The technical solution of the utility model further can also realize by following measure:
Long-tail nut band internal thread is reserved the needed platform of flange port according to the caliber difference in it.
Hollow swivel nut band outside thread, hollow swivel nut contact end face with body flange interface geometrical shape is plane or circular arc or wedge shape.
The flange of pipe end is the 85-95 degree.
The hardness of long-tail nut and hollow swivel nut the selection of material is greater than the hardness of body.
Compared with the prior art, the outstanding technique effect that the utlity model has:
1, simple and reasonable, be rigidly connected entirely, straight-through head only needs long-tail nut and two parts of hollow swivel nut, and processing cost is minimum, connects most convenient.
2, long-tail nut and hollow swivel nut can have been saved cost greatly with the common iron of hardness greater than tubing.
3, joint gap is little, and the pipe end joint does not need to process the connection geometrical shape of uneven distortion, and it is resident not have residue, is particularly suitable for the FLUID TRANSPORTATION of heterogeneity.
4, mechanical strength is good, has strengthened being connected the stability of pipe, is fit to the conveying of various high low pressure liquid, gas.
5, no problem of aging, vibration resistance is not leaked, and is solid and reliable, is difficult for change, thoroughly solved pipeline and imbedded the permanent problem of using in underground, body of wall and the object.Be particularly suitable for the use of industries such as chemical industry, pharmacy, food.

Specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to figs. 1 to Fig. 5, the utility model comprises tapped long-tail nut 1, is with externally threaded hollow swivel nut 2, the body 3 of termination flange.Thin-wall metal body 3 ports special tool flange, flange 3-1 is near 90 degree.Reserve the needed platform of flange interface (1-1) according to body 3 caliber differences in the long-tail nut 1, hollow swivel nut 2 contacts the geometrical shape of end face 2-1 with body 3 flange interfaces, is determined by the size of body 3 calibers, carry out the transition to by the plane circular-arc, wedgelike etc.; When body 3 calibers hour, can adopt plane shape, when caliber is big, can adopt circular arc or wedge shape.The hardness of long-tail nut 1 and hollow swivel nut 2 the selection of materials is more than or equal to the hardness of metal body 3.The flange 3-1 of two sections body 3 terminations wherein one section penetrate in the long-tail nut 1, another section penetrates butt joint in the hollow swivel nut 2, screws long-tail nut 1 and hollow swivel nut 2, the pressure by adjusting hollow swivel nut 2 and long-tail nut is with the flange 3-1 sealing of two sections bodys 3.The tail of long-tail nut 1 is long, according to the caliber size proper extension that is connected body, is connected the stability of body with suitable increase.In addition according to the size and the thickness that are connected body, can suitably adjust the geometric angle (carrying out the transition to circular-arc, wedgelike etc. by the plane) of hollow swivel nut 2 crimping end face 2-1, reduce screwing pressure, increase and connect sealing effect.The utility model can be isometrical, reducing coupling joint, 45 degree, the 90 degree elbows of various bores, various isometrical, reducing tees, cross fitting.
