Description
Technical field
The utility model and a kind of socket joint connection pipe fitting belong to pipe fitting interconnection technique field.
Background technique
In the plumbing of indoor and outdoors such as industrial premises, civil building, often adopt the socket joint connection pipe fitting, these adopt the pipe fitting of socket joint Placement that tubing such as UPVC, PVC-U, cast iron tube, concrete pipe are arranged.Wherein the Placement of UPVC, PVC-U tubing is socket joint and connects the bonding mode that adds.For pipe laying and prevent pipe leakage, all before pipe fitting inner wall and pipeline outer wall socket joint, smear special plastic glue.Whether there are foreign material determining pipeline whether to leak in whether evenly the smearing of glue, the pipe fitting joint socket and problem that whether piping erection is firm.In order to guarantee the piping erection quality, generally all can adopt the good glue of quality, basically all be the problem that disposable use is promptly scrapped with regard to having produced pipe fitting like this, when in case error being installed or percolating water phenomenon being arranged, must use new pipeline and pipe fitting to reinstall, this has not only wasted tubing, has also increased installation cost.And traditional cast iron tube adopts more being connected to be with concrete pipe at present: the former is flexible clip connected, and cost is higher; What the latter adopted is rubber seal, and slush is fixed, and again at joint winding steel wire net, last making cement mortar is smeared band, like this construction process complexity and cause leakage easily.Therefore the connecting means of existing bayonet joint pipe fitting still is not ideal enough.
Summary of the invention
The purpose of this utility model is: provide a kind of do not need glue bonding, can reuse and socket joint connection pipe fitting easy for installation, good seal performance, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of socket joint connection pipe fitting of the present utility model comprises top tube and down tube, in last pipe, be provided with step hole, on the step of last pipe step hole, the high elasticity sealing rubber ring is housed, and being fixed with at least 2 cards that protrude inner round wall on the inner round wall than large diameter hole of the step hole of last pipe turns round, on the outer cylinder than large diameter hole that can inject the pipe step hole of following pipe, be provided with card and turn round the guiding locked groove, card is turned round one section straight trough for tube hub line under being parallel to of guiding locked groove, and be provided with the crotch shape locked groove of arc transition at the straight trough end, the quantity that card is turned round the guiding locked groove is with to block the quantity turn round identical, and when pipe connects on pipe injects down, on it card of pipe turn round also can inject respectively card turn round the guiding locked groove in, and the following end of pipe compress tight on during high elasticity sealing rubber ring in the pipe step hole, its card is turned round and can be sticked into card and turn round in the crotch shape locked groove of the locked groove that leads.
Be provided with annular groove on the step of pipe step hole on above-mentioned, the high elasticity sealing rubber ring is contained in the annular groove.
Above-mentioned going up pipe or manage down is the pipe fitting of straight tube, bend pipe or three-way pipe shape.
Because adopted technique scheme, the utility model to overcome when plastic socket pipe fitting is bonding can only disposablely to use, the cast iron tube socket joint connects flexible clip cost costliness and the concrete pipe construction process complicated and the shortcoming of easily leaking.Pipe fitting of the present utility model can be removed at any time and check and repeat installation; There is high elastic rubber to seal, also solved the insecure shortcoming of glue sealing.Therefore, the utility model compared with prior art, that the utility model not only has is easy for installation, do not need when installing glue bonding, can repeat to install and use, the advantage of good seal performance, but also have that using effect is good, reliability is high, advantage such as with low cost, long service life.

Embodiment
Embodiment of the present utility model: a kind of socket joint connection pipe fitting of the present utility model comprises pipe 1 and manages 2 down, last pipe 1 and following pipe 2 can adopt traditional UPVC, PVC-U, cast iron, cast steel, stainless steel, material such as non-ferrous metal or concrete, can be made into traditional straight tube with going up pipe 1 or managing 2 down, bend pipe, or the pipe fitting of three-way pipe shape, during making, in last pipe 1, produce step hole, high elasticity sealing rubber ring 5 can be placed on the step of pipe 1 step hole, and on the same circumference than the inner round wall of large diameter hole of the step hole of last pipe 1, produce at least 2 cards that protrude inner round wall and turn round 3, make 4 cards generally speaking and turn round 3 and get final product by even distribution; Manage down 2 can inject pipe 1 step hole than the outer cylinder of large diameter hole on make card release and turn round guiding locked groove 4, card is turned round guiding one section of locked groove 4 to be made into and to be parallel to the straight trough of pipe 1 center line down, and produce the crotch shape locked groove of arc transition at the straight trough end, the quantity that card is turned round guiding locked groove 4 is made into and blocks that to turn round 3 quantity identical, pipe 2 is injected go up when managing 1 connection, pipe card of 1 is turned round 3 and also can be injected card respectively and turn round in the locked groove 4 that leads on it, and the end of managing 2 down compress tight on during high elasticity sealing rubber ring 5 in pipe 1 step hole, its card is turned round 3 and can be sticked into card to turn round the crotch shape locked groove of guiding locked groove 4 interior.
In order to reach better connection effect and sealing effect, can on the step of last pipe 1 step hole, produce an annular groove 6, and then high elasticity sealing rubber ring 5 is put in the annular groove 6; For the purpose of reliable, also can adopt bonding method that high elasticity sealing rubber ring 5 is bonded in the annular groove 6.High elasticity sealing rubber ring 5 can adopt high elasticity sealing rubber ring finished product of the prior art.
During making, on manage card on 1 turn round 3 or down the card on the pipe 2 turn round mode that guiding locked groove 4 can adopt moldings formed therefrom with last pipe 1 or manage down 2 be made as simultaneously one-body molded.
The connecting means of the socket joint connection pipe fitting that the utility model adopted is to comprise adopting an existing pipe fitting is injected to carry out the method that socket joint connects in another root pipe fitting, when two pipe fittings being carried out the socket joint connection, in advance a pipe fitting with step hole than the inner round wall of large diameter on fixing at least 2 cards that protrude inner round wall turn round, and on the step in the step hole of this pipe fitting the high elasticity sealing rubber ring is set; Producing quantity on the outer cylinder of another root pipe fitting turns round the identical card of quantity and turns round the guiding locked groove with card, each card is turned round guiding one section of locked groove all be made as the straight trough that is parallel to this pipe fitting center line, and produce the crotch shape locked groove of arc transition at the end of straight trough, to have card then turns round the pipe fitting of guiding locked groove and injects and to have in the pipe fitting of step hole, its card is turned round stick into respectively card to be turned round in the guiding locked groove, when having after card turns round high elasticity sealing rubber ring in the pipe fitting that the end of pipe fitting of guiding locked groove will have step hole and compress, turning round the card of guiding in the locked groove at card turns round and just in time arrives crotch shape locked groove place, at this moment make two pipe fittings do opposite rotation by artificial method, card is turned round enter into card to be turned round in the crotch shape locked groove of guiding locked groove, thereby the mode by socket joint and turn round by card fixes and the mode of high elasticity sealing rubber ring elastic tension links together two pipe fittings, and the joint of two pipe fittings is sealed by the high elasticity sealing rubber ring.
