Abstract
The model is a stainless steel pipe joint. A symmetric extraversion flanging is applied in two ends of the connected stainless steel pipe joint. A cross section combined with the extraversion is arranged between two flanging as the seal gasket for a trapezoid. A screw nut and a silk ring for purpose of pressing are arranged on the external surface. Inward stress produced by the positive V model structure not only overcomes the defect that loosening and prolepses is easy to appear in the seal gasket of the current vertical flanging structure, but also improves sealing property of the device. In order to strengthen rigidity in the joint, inner intubations are arranged at the end of two steel pipes; long tail of the one body nut or the flexible brake joint nut covering the steel pipe is arranged on the lateral side of the nut.
Description
(1) technical field: a kind of stainless steel joint for pipeline, mainly use the what water drinking tube, belong to pipe joint (F16L) in the engineering element.
(2) background technique:
For human health,, be a kind of optimized choice as water supply line with thin-wall stainless steel in order to make potable water not because of pipe material for water supply is subjected to secondary pollution.
Disclosed at present stainless steel joint for pipeline, easy to maintenance in order to dismantle, the especially connection of exposed conduit part, the loose joint structure that has adopted the nut wire ring to compress, it interior two is connected Stainless Steel Tubes and adopts vertical flange to compress between the two sealing gasket.Through facts have proved, vertical turnup structure is influenced by external force, and nut wire ring screw thread is impaired, very easily causes sealing gasket loosening and outwards deviate from, and causes joint to lose sealability.
(3) summary of the invention:
The utility model is exactly the problem that solves the vertical turnup structure sealing of above-mentioned stainless joint difference.Its technological scheme is as follows:
Positive V-type inner-intubation stainless steel joint for pipeline, nut 4 with band internal thread 4.1, the wire ring 5 of the outside thread 5.1 that band is meshed with it is characterized in that the flange 2 of connected two stainless steel pipes 1 termination is outward-dipping for symmetry, and between two flange the shape of cross section that matches being set is trapezoidal sealing gasket 3; Nut and wire ring respectively with flange between power transmission face also match with flare flange face.
Establish an interpolation pipe 6 being connected two stainless steel pipe 1 two ends section endoporus; And trapezoidal sealing gasket 3 overlaps the outer surface, garden of what interpolation pipes, or sets up groove 6.1 at this place.
Or establish the nut long-tail 4.3 that is connected as a single entity in the nut outside or with the loose joint long-tail 4.4 of thread engagement.
The V-arrangement angle α that two flange form is taken as 0 ° of big what, 130 ° of little whats.
The material of nut and wire ring adopts any one in stainless steel, ABS nickel plating, copper nickel plating, hard aluminium alloy, the carbon steel nickel plating.Trapezoidal sealing gasket 3 usefulness rubber are made.
The utility model beneficial effect:
1. adopt positive V-type turnup structure, when nut wire ring screw thread has looseningly, weaken though the suffered axial pressing force of seal ring has, because of the V-type effect is arranged, trapezoidal seal ring still receives inside thrust and makes seal ring keep suitable rate of tension and can not deviate from.2. interpolation pipe is established in the joint, in order to reinforced joint rigidity, guarantees that further seal ring do not deviate from.3. but be provided with nut long-tail reinforced joint place rigidity and reduce distortion.Adopt the loose joint long-tail more conveniently to select for use as required, cost-saved.
(4) description of drawings:
Fig. 1 the utility model embodiment 1 (inner-intubation)
Fig. 2 the utility model embodiment 2 (nut long-tail type)
(5) embodiment:
Embodiment 1
See Fig. 1, a kind of Stainless Steel Tube straight joint.Two are connected Stainless Steel Tube 1 termination that the sectional shape that matches with it is housed between outward-dipping flange 2, two flange is that rubber gasket 3, the two waist elongation lines of isosceles trapezoid form positive V-type, and its angle α is taken as 30 °.In two stainless steel tube head sections, to set up-stainless steel interpolation pipe 6, the two ends section overlapping with interpolation pipe only needs reaming just can inject.Contact the face place on the interpolation pipe surface with trapezoidal sealing gasket and open a spill annular groove 6.1, with the steadiness and the sealing of enhanced leaktightness pad.
Nut 4 (being 4a among Fig. 1 here), wire ring 5 are equipped with in steel pipe 1 outside, and both compress seal ring and form the loose joint structure by screw thread 4.1 and 5.1 engagements.The power transmission face 4.2 that both contact with two flange respectively and 5.2 its shapes match with flare flange face.
Embodiment 2
See Fig. 2, if interior insertion pipe 6 (see figure 1)s among the embodiment 1 are not set, this nut is the 4b (see figure 2).Can establish the nut long-tail 4.3 that is connected as a single entity in the nut 4b outside or adopt internal and external threads to live and connect, make independent knock-down long-tail 4.4.The nut wire ring adopts stainless steel.All the other structures and embodiment 1 are identical.
Claims (6)
1. positive V-type inner-intubation stainless steel joint for pipeline, nut (4) with band internal thread (4.1), the wire ring (5) of the outside thread (5.1) that band is meshed with it, the flange (2) that it is characterized in that connected two stainless steel pipe (1) terminations is outward-dipping for symmetry, and between two flange the shape of cross section that matches being set is trapezoidal sealing gasket (3); Nut and wire ring respectively with flange between power transmission face also match with flare flange face.
2. by the described joint of claim 1, it is characterized in that being connected two stainless steel pipe two ends endoporus and establish an interpolation pipe (6); And trapezoidal sealing gasket (3) overlaps the outer surface, garden of what interpolation pipe, or sets up groove (6.1) at this place.
3. by the described joint of claim 1, it is characterized in that the nut long-tail (4.3) that is connected as a single entity is established in the nut outside or with the loose joint long-tail (4.4) of thread engagement.
4. by the described joint of claim 1, it is characterized in that the V-arrangement angle α that two flange form is taken as 0 ° of big what, 130 ° of little whats.
5. by the described joint of claim 1, the material that it is characterized in that nut and wire ring adopts any one in stainless steel, ABS nickel plating, copper nickel plating, hard aluminium alloy, the carbon steel nickel plating.
6. by the described joint of claim 1, it is characterized in that trapezoidal sealing gasket makes of rubber.
