Abstract
The utility model relates to a metal restriction joint of a pressure-bearing plastic pipe, which comprises pipe materials, wherein clearances are arranged between the pipe materials, the positions of the clearances of the pipe materials are provided with two or more Haffs which are mutually fixed, and the insides of the inner cavities of the Haffs are provided with sealing rings covering the clearances. The utility model has the beneficial effects that the utility model has strong capability of resisting geological deformation and is suitable for the use in places with poor geological conditions and severe environments; and meanwhile, the utility model can be used during rush repair.
Description
Technical field
The utility model relates to a kind of pressure-bearing plastic tube, especially a kind of pressure-bearing plastic tube metal constraint joint.
Background technique
The often anti-geological deformation ability in existing pressure-bearing joint for plastic tube place a little less than, geological condition difference local broken easily and reveals, and causes the direct loss of economy.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of good airproof performance, anti-geological deformation ability strong pressure-bearing plastic tube metal constraint joint.
The utility model solves the technological scheme that its technical problem adopts: this pressure-bearing plastic tube metal constraint joint, comprise tubing, be provided with the gap between the tubing, the gap location of tubing is equipped with two or above Hough fastened to each other, is provided with the seal ring of coverage gap in the inner chamber of Hough.
As preferably, described Hough is carved face by sawtooth and is pressed on tubing, guarantees to have the enough anti-intensity of drawing.By bolton, structural safety is reliable between the described Hough.
As preferably, described seal ring is provided with the Y shape chamber that is communicated with the gap.Described seal ring adopts silicone rubber material.Inside water pressure enters the Y shape chamber from the tubing gap, and seal ring presses the Hough inwall, and the big more sealing of interior pressure is good more.
As preferably, described Hough shell is the smart casting of spheroidal graphite cast iron.Surface anticorrosion, antirust processing, reasonable in design, in light weight.
The effect that the utility model is useful is: the anti-geological deformation ability of the utility model is strong, is applicable to the place use that geological condition is poor, environment is abominable, uses when can be used as repairing simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional view of the present utility model;
Description of reference numerals: Hough 1, seal ring 2, tubing 3, sawtooth are carved face 4, inner chamber 5, Y shape chamber 6, gap 7.
Embodiment
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing:
Embodiment one: as Fig. 1, this pressure-bearing plastic tube metal constraint joint, comprise that diameter is 250 millimeters a tubing 3, be provided with gap 7 between tubing and the tubing 3, the sawtooth that 7 places, gap are provided with by internal surface by binary two Houghs 1 is carved face 4 cards and is pressed, and the Hough shell is the smart casting of spheroidal graphite cast iron, and do antiseptic and rustproof processing, between Hough and the Hough 1 by bolton, 5 li seal rings 2 that are provided with the employing silicone rubber material of coverage gap 7 of the inner chamber of Hough 1, seal ring 2 is provided with the Y shape chamber 6 that is communicated with gap 7.
Embodiment two: this pressure-bearing plastic tube metal constraint joint, comprise that diameter is 300 millimeters a tubing 3, and 7 places, gap between the tubing 3 are pressed by three Houghs, 1 card of trisection, and all the other are with embodiment one.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
