Description
Technical field
The utility model relates to conduit fittings technical fields, more particularly to a kind of PVC-U pipe fast connector.
Background technique
PVC-U pipe, also referred to as UPVC pipe or hard PVC pipe, it is the aggregated reaction of vinyl chloride monomer and manufactured nothing is fixed
Shape thermoplastic resin adds certain additive (such as stabilizer, lubricant, filler), is squeezed, injection molding.PVC-U pipe
Have the characteristics that material is light, corrosion-resistant, fluid resistance is small, mechanical strength is big, does not influence water quality, is widely used in municipal administration, building
The water supply and sewage work pipe in equal fields.
Currently, the connection of fixed port mainly uses end-face seal ring sealing, thread bush in pipeline construction installation process
The mode of connection is bound round, and it is to use process corresponding groove and flaring, directly dock gluing or add that scene, which cuts pipe port then,
Work groove is attached by way of cuff/connector gluing connection, is existed by the way of the connection of screw thread cuff bonding pad
Poor sealing effect, the problem of small space construction and installation inconvenience, and adhesive means connection is used, it often will appear bonding site
Glue ageing failure cause pipe leakage even disconnecting the problem of.
Utility model content
Place in view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of PVC-U pipeline is quick
Connector has the characteristics that compact-sized, sealing effect is good, is easily installed.
The purpose of this utility model is achieved through the following technical solutions：
A kind of PVC-U pipe fast connector, including connecting tube, connection cuff and sealing ring, the end of the connecting tube
It is provided with connection male connector；The sealing ring include the lining ring that section is prismatic and be arranged in outside lining ring the ring spacer of middle side part and
It is structure as a whole；Several spiral convex blocks are provided on the connection male connector outer wall, the front end of the connection cuff is provided with annular
Limited block, has circumferentially been arranged alternately several mounting grooves and spiral helicine locating piece on the inner wall of rear end, the mounting groove with connect
Spiral convex block in male connector matches, and the interior side elevation of the locating piece is provided with interior non-slip process, on the spiral convex block with
Interior non-slip process is correspondingly arranged on outer non-slip process, and the sealing ring setting is in connection cuff.
In order to preferably realize the utility model, the connecting tube is bend pipe.
Further, the inner wall of end of the connection male connector is in ramp shaped, and the normal of slope surface and the angle of pipe axis are 5-
15°。
Preferably, the spiral convex block is circumferentially uniformly distributed and along axis three-layer set, corresponding to central angle is
60 °, interlamellar spacing is identical as the thickness of spiral convex block.
Further, the connecting tube is T-shape tee tube.
Further, the section of the sealing ring is Y-shaped.
Preferably, the sealing ring is one of hard materials such as PVC-U, 304 stainless steels.
The utility model compared with the prior art, has the following advantages that and beneficial effect：
1, the sealing ring combined using integrated lining ring and ring washer is carried out liner sealing to interface portion position, is located at
For the lining ring of pipe inner part under the effect of tube fluid pressure, the sealing effect between tube wall is more preferable；
2, using the convex block of connection male connector and by the way of connecting the groove cooperation of cuff inner wall, rapid abutting joint fastening is realized,
Facilitate installation；
3, the structures such as non-slip process are set on the contact surface between convex block and groove, avoid connection male connector with connect cuff
After fastening, the problem of loosening, disconnect under the effect of prolonged tube fluid pressure.
