Abstract
The utility model discloses a rigid and flexible sewage filtering telescopic joint which comprises a rubber telescopic tube with a corrugated protrusion, flanges arranged at both ports of the rubber tube and extended outwards along the radial direction, and a filter cartridge arranged in the tube body positioned between both of the two ports of the rubber telescopic tube. The bottom of the filter cartridge is provided with a stopper which is combined with the rubber telescopic tube wall by a connector in a sealing way, and the inner of the rubber telescopic tube wall is provided with a metal net layer. The utility model has the advantages that the metal net layer is arranged in the rubber telescopic tube wall, and the bearing strength and the service life of the rubber telescopic tube are increased greatly. The running expense of the water supply pipeline is reduced, and the maintenance work amount is reduced simultaneously.
Description
Technical field:
The utility model relates to a kind of dirty rubber expansion joint of filter that is used on the water supply line.
Background technique:
Filter dirty rubber expansion joint and be mainly used on the water supply line, be used for the impurity of water in the filtering pipeline, to guarantee quality of water supply.Because the needs of use occasion, filter dirty rubber expansion joint and often be subjected to the effect of radial and axial power, make that the working life of this joint is shorter, bear positive and negative pressure and descend, increased the operating maintenance expense of water supply line, especially on large diameter pipeline, used just to seem more like this.
The model utility content:
The purpose of the utility model is to provide strong, the long-lived hard and soft filter of a kind of bearing capacity dirty expansion joint at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be achieved through the following technical solutions:
The utility model comprises the rubber bellows that have the ripple projection, be arranged on the flange that extends radially outward of described rubber tube terminal mouth, and be set in place the filter cylinder in the body between the rubber bellows two-port, bottom at described filter cylinder is provided with plug, described plug combines with the sealing of rubber bellows wall by coupling, is provided with the metal stratum reticulare in the tube wall of described rubber bellows.
On the rubber bellows that are positioned at described two flange inboards, be respectively installed with one with the mounting flange of described flange equivalent diameter.
Advantage of the present utility model is to be arranged on the metal stratum reticulare in the described rubber bellows tube wall, thereby improved the bearing strength of rubber bellows widely, prolong working life, not only reduced the operating cost of water supply line, also reduced maintenance load simultaneously.
Description of drawings:
Fig. 1 cuts open figure for master of the present utility model.
Embodiment:
As shown in the figure, the utility model comprises the rubber bellows 2 that have ripple projection 1, be arranged on the flange that extends radially outward 3 of described rubber pipe 2 two-port, and be set in place the filter cylinder 4 in the body between rubber bellows 2 two-port, be provided with plug 5 in the bottom of described filter cylinder 4, described plug 5 combines with the sealing of rubber bellows 2 tube walls by coupling, is provided with metal stratum reticulare 6 in the tube wall of described rubber bellows 2.For ease of installing, on the rubber bellows 2 that are positioned at described two flange 3 inboards, be respectively installed with one with the mounting flange of described flange 3 equivalent diameter.
