Abstract
The utility model relates to a quick spigot-and-socket joint type plastic pipe connector with a cover fastener. A tapered inner hole is arranged in a pipe connector body. A sealing ring and a tapered cutting sleeve are arranged in the tapered inner hole. The inner wall of the cutting sleeve is provided with a one-way gullet. The outer wall of the cutting sleeve is a conical surface, and the cutting sleeve is provided with a swelling bayonet. The quick spigot-and-socket joint type plastic pipe connector with a cover fastener has the advantages of simple component, simple operation, and high fluid pressure enduring. The utility model can be applicable to various water delivery or liquid delivery pipelines.
Description
The utility model belongs to a kind of pipe connector, particularly a kind of quick spigot and socket type cutting ferrule plastic tube fitting.
At present, most of mechanical type pipe connector or the spigot and socket type pipe connector of adopting of the connection of tubing.Mechanical type pipe connector major part is to be threaded, except that seal ring is arranged, and the cover that also will be installed that has, and, withstand seal ring with this at pipe fitting two ends installation sealing cover, and so structural member is many, the cost height, it is lower to bear hydrodynamic pressure.The spigot and socket type pipe connector generally is used on the plastic tube, mainly is by seal ring sealing and chucking.So after pipe connector and tubing were installed and is connected, it was low to bear hydrodynamic pressure, when the pipeline hydrodynamic pressure was high slightly, the pull-off phenomenon will appear in pipe fitting and tubing, and what have must not no longer remedy with adhesives, therefore, complicated operation, using effect is poor.
The purpose of this utility model is to overcome deficiency of the prior art and a kind of quick spigot and socket type cutting ferrule plastic tube fitting that hydrodynamic pressure height, pipe connector and tubing are difficult for pull-off that bears is provided.
The purpose of this utility model can realize by following measure:
The structure of spigot and socket type cutting ferrule plastic tube fitting is fast, is provided with cone-shaped inner hole (4) in pipe connector body (1), is adorning seal ring (5) and cutting ferrule (6) in the cone-shaped inner hole, and the bayonet socket of rising (9) is arranged on the cutting ferrule.
The structure of spigot and socket type cutting ferrule plastic tube fitting can also be fast, the inner chamber of pipe connector body (1) can cooperate endoporus (3) and cone-shaped inner hole (4) to constitute by pipe connector endoporus (2), tubing, in the middle of it is pipe connector endoporus (2), pipe connector endoporus two ends are respectively that the tubing that matches with tube outer diameter cooperates endoporus (3), it is cone-shaped inner hole (4) that tubing cooperates the other end of endoporus, and its awl half-angle is 0 °＜α＜8 °.
Cutting ferrule can be tapered, and its outer wall (7) is a conical surface, and the awl half-angle is 0 °＜β＜10 °, and inwall is a plurality of inwardly oblique unidirectional teeth groove (8).
The pipe connector of above-mentioned various structural types can be lead directly to, the pipe connector of patterns such as curved logical, threeway, reducing.
The utility model compared with prior art has following advantage:
1, member is simple, need not add threaded and sealing cover;
2, easy and simple to handle, the tubing insertion tube fitting that only need will cut chamfering can be finished the installation connection of tubing;
3, bear the hydrodynamic pressure height, anti-pulling capacity is strong, compare with same material, other constructed products of same specification double many;
4, applied range, applicable to the connection of all kinds of water transport pipelines with plastic tube, as bury ground or outdoorly give, water drainage plastics pipe, urban architecture be with the connection with plastic tube of plastic tube, rural area irrigation and drainage and various water supply project; Also can be used for the connection of industrial some plastic tube.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the quick spigot and socket type cutting ferrule of a utility model plastic tube fitting structural representation;
Fig. 2 is cutting ferrule cross section, a Figure 1A place enlarged diagram;
Fig. 3 is the quick spigot and socket type cutting ferrule of a utility model plastic tube fitting user mode schematic representation.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Fast the structure of spigot and socket type cutting ferrule plastic tube fitting as shown in Figure 1 and Figure 2, the inner chamber of the pipe connector body made from nontoxic, tasteless PP or PE glass reinforced plastic (1) cooperates endoporus (3) and cone-shaped inner hole (4) formation by pipe connector endoporus (2), tubing.In the middle of it is pipe connector endoporus (2), and pipe connector endoporus two ends are respectively that the tubing that matches with tube outer diameter cooperates endoporus (3), and it is cone-shaped inner hole (4) that tubing cooperates the other end of endoporus, and its awl half-angle α is 5 °.Adorning rubber seal (5) and taper cutting ferrule (6) in the cone-shaped inner hole.The outer wall of cutting ferrule (7) is a conical surface, and its awl half-angle β is 6 °, and the inwall of cutting ferrule has a plurality of inwardly oblique unidirectional teeth groove (8).The bayonet socket of rising (9) is arranged on the cutting ferrule.
Spigot and socket type cutting ferrule plastic tube fitting user mode in the insertion tube fitting is located plastic tube (10) and (11) of two butt head chamferings respectively as shown in Figure 3 to tubing cooperation endoporus (3) fast, and the installation of promptly having finished plastic tube (10) and (11) is connected.In this process before this plastic tube taper cutting ferrule spreading is then passed seal ring (5), and it is sleeved on the plastic tube.When plastic tube is subjected to the outside drawing of axial force, be with seal ring (5) and cutting ferrule (6) outwards to move, the anti-taper hole of seal ring with outer and cutting ferrule outer cone and pipe connector intracoelomic cavity is interacted, make sealing of pipe connector and plastic tube and chucking.Under the effect of teeth on the cutting ferrule, plastic tube pulls outward more, and it is tight more that cutting ferrule blocks plastic tube, and sealing is good more.
