Description
Technical field
The utility model relates to a kind of water joint, particularly relates to a kind of waterproof system joint.
Background technique
Water joint on domestic market generally adopts air hole straight up and down, and waterproof ventilated membrane adopts back glue type, the mode compressed with briquetting, and this just makes the air hole of product very little, the efficiency that impact is ventilative, and Air permenbility is very little; , great water-leaking property can be there is in the back glue type waterproof ventilated membrane adopting briquetting to compress, and by the service condition of gum and the impact in life-span; Adopt back glue type in addition or compress back glue type waterproof ventilated membrane situation with briquetting, waterproof ventilated membrane can be made to become product extreme lower position, once there be water droplet to drop on waterproof ventilated membrane surface, likely that water covers film completely, it is made to lose ventilative function, water droplet has been grown at superficial residence time, also can there is the possibility of leaking; Adopt the modes such as interference pressing, fastening between buckle closure and inhalation valve body, coupling mechanism force and moment of torsion are very little, are easy to destroy waterproof ventilated membrane when external environment is severe.
In addition, the heat-resisting quantity of existing PPR water pipe joint, resistance to pressure is slightly poorer, and Long-term service temperature can not more than 70 DEG C, and can not construction be bent, can not to carry out disinfection sterilization to the medium flowed through, therefore be necessary to improve existing water joint, improve bulk strength, heat-resisting quantity, resistance to pressure.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of waterproof system joint, which increase the Air permenbility of product, improve waterproof, ventilative reliability, bulk strength, heat-resisting quantity, resistance to pressure and torque resistant, and there is certain disinfecting sterilization function.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of waterproof system joint, comprise pipe coupling, wherein, vent valve is provided with in described pipe coupling, described vent valve comprises O type circle, waterproof ventilated membrane, inhalation valve body, buckle closure and threaded end, described O type circle is positioned on threaded end, described waterproof ventilated membrane and this body by integral forming of inhalation valve, the shape of described waterproof ventilated membrane and inhalation valve body is all arch, integral by ultrasonic welding after described buckle closure and inhalation valve body snapping; Described pipe coupling comprises polypropylene resin layer, metal frame layer and antibacterial resin layer from outer successively toward interior, described metal frame layer is connected with polypropylene resin layer by the first heat-fusing glue layer, and described metal frame layer is connected with antibacterial resin layer by the second heat-fusing glue layer.
Above-mentioned waterproof system joint, wherein, described metal frame layer is the metal aluminum pipe that multistage welds together.
Above-mentioned waterproof system joint, wherein, described antibacterial resin layer is acrylic resin pipe, and described acrylic resin pipe internal surface is coated with silver ion thin layer.
Positive progressive effect of the present utility model is: the utility model arranges vent valve in pipe coupling, adopt waterproof ventilated membrane and the inhalation valve body of inclined opening type arch, maximum expansion vapor permeation area, increase product Air permenbility, and waterproof ventilated membrane intermediate portion is at the highest notch all the time, even if having water droplet to fall also can not affect product gas permeability; Pipe coupling adopts multi-layer compound structure, has certain restraining and sterilizing bacteria function, and can improve pipeline bulk strength, heat-resisting quantity, resistance to pressure; The utility model adopts advanced injection molding technology, waterproof ventilated membrane and inhalation valve body is fused into reliably one, significantly increases the reliability of waterproof; After buckle closure fastens, adopt device for ultrasonic welding buckle closure and inhalation valve body to be welded together firmly, improve product torque resistant performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model waterproof system joint;
Fig. 2 is the pipe coupling close-up schematic view of the utility model waterproof system joint.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the waterproof system joint that the utility model provides, comprise pipe coupling 6, wherein, vent valve is provided with in described pipe coupling 6, described vent valve comprises O type circle 1, waterproof ventilated membrane 2, inhalation valve body 3, buckle closure 4 and threaded end 5, described O type circle 1 is positioned on threaded end 5, described waterproof ventilated membrane 2 is one-body molded with inhalation valve body 3, the shape of described waterproof ventilated membrane 2 and inhalation valve body 3 is all arch, integral by ultrasonic welding after described buckle closure 4 and inhalation valve body 3 snapping; Described pipe coupling 6 comprises polypropylene resin layer 61, metal frame layer 63 and antibacterial resin layer 65 from outer successively toward interior, described metal frame layer 63 is connected with polypropylene resin layer 61 by the first heat-fusing glue layer 62, and described metal frame layer 63 is connected with antibacterial resin layer 65 by the second heat-fusing glue layer 64.
The waterproof system joint that the utility model provides, the metal aluminum pipe that described metal frame layer 63 welds together for multistage.Described antibacterial resin layer 65 is acrylic resin pipe, and described acrylic resin pipe internal surface is coated with silver ion thin layer.
The utility model waterproof system joint has following characteristics:
One, the shape of inhalation valve body is arch, increases the vapor permeation area of product further, expands air hole, and the intermediate portion of waterproof ventilated membrane 2 is at the highest notch all the time, even if there is water droplet to fall, also can ensure gas permeability.
