Abstract
The utility model discloses a duplex fitting with fast activity of pipeline, and consists of a central pipe body and two connecting tube fitting. The utility model is characterized in that the two ends of the central tube body is provided with a claw which is higher than the outside surface of the pipe; the central pipe body is provided with a connector with internal thread which is communicated with the inner cavity of the central pipe body; one end of the connector is a double-layer pipe wall and the outer pipe wall is higher than the outside surface of the connector; a gland bush is arranged between the two pipe walls; the connector is sleeved with a connecting hoop which is provided with a pawl which is rotary connected with the claw. The utility model has the advantages of being convenient for fixation and using, safe in using, greatly raising the connecting speed, detaching conveniently, avoiding the loss of the connecting hoop, and having a certain popularization and application value.
Description
The utility model belongs to pipeline interconnection technique field, especially relates to a kind of pipeline connection activity tee union fast.
Our some triplate line joints of using at present, relatively simple for structure, be to use mostly and be threaded, like this use cumbersome, need to use special tool to connect, connect complicated, connection speed is slow, and must use the threaded tubing of hard to connect, such connection simultaneously makes pipeline more fixing, moves cumbersomely, and not being suitable for needs interim place of laying pipeline, very inconvenient when especially use the rural irrigation, thereby the incompatible present needs of existing three-limb tube head.
The purpose of this utility model is to provide a kind of pipeline that can carry out rapidly and accurately to connect, easy accessibility, safe and convenient to use, and high working efficiency connects the tee union that hoop is difficult for losing.
The purpose of this utility model is to realize like this, a kind of tee union, being connected tube head by middle body with two forms, be characterized in being provided with the pawl that exceeds outer surface of tube body at the two ends of middle body, the body of middle body is provided with the connection mouth that has internal thread, connection mouth communicates with the inner chamber of middle body, an end that connects tube head is that double-layer tube wall and outer tube wall exceed the outer surface that connects tube head, be provided with sealing gasket between double-layer tube wall, connect hoop connecting to be with on the tube head, connect hoop be provided with can with the pawl ratchet that spins.
In order further to realize the purpose of this utility model, can also be to be provided with boss after connecting the double-layer tube wall of tube head, be provided with between boss and double-layer tube wall with the tube wall lock ring together and exceed the Flexible clamp on boss plane, connect hoop and be fixed between Flexible clamp and double-layer tube wall.
The utility model has following distinguishing feature compared with the prior art: owing to be provided with the pawl that exceeds outer surface of tube body at the two ends of middle body, the body of middle body is provided with the connection mouth that has internal thread, connection mouth communicates with the inner chamber of middle body, an end that connects tube head is that double-layer tube wall and outer tube wall exceed the outer surface that connects tube head, be provided with sealing gasket between double-layer tube wall, on the connection tube head, be with and connect hoop, connect hoop be provided with can with the pawl ratchet that spins, so just can pipeline be coupled together by spinning of ratchet and pawl, do not use and be threaded, avoided the use special tool, accelerated connection speed, pipe racks can be socketed in simultaneously on the binding tube head, be not with being can simply dismantle to take away, and connects the maximum outside diameter of the minimum diameter of hoop less than Flexible clamp, connecting hoop so just can not come off from tube head, such structure makes connection two tube heads more simple, at a high speed, increase work efficiency, and connect hoop and be difficult for losing, avoided waste.
Below in conjunction with drawings and Examples a kind of tee union of the utility model is described in further details.
Fig. 1 is the structural representation of a kind of tee union of the utility model.
Fig. 2 is the another kind of structural representation of a kind of tee union of the utility model.
Embodiment 1, with reference to Fig. 1, a kind of joint, be on the two ends of middle body 1, to be provided with the pawl 3 that exceeds body 1 outer surface, pawl is more than 3 at least two, present embodiment adopts three pawls 3, the body of middle body 1 is provided with the connection mouth 4 that has internal thread, connection mouth 4 communicates with the inner chamber of middle body 1, and an end that connects tube head 2 is that double-layer tube wall and outer tube wall exceed the outer surface that connects tube head 2, is provided with sealing gasket 5 between double-layer tube wall, on connection tube head 2, be with and connect hoop 6, connection hoop 6 is provided with can be just the same with 7, two structures that connect tube head 2 of ratchet that pawl 3 spins, and this has constituted a kind of static structure of the present utility model.
Embodiment 2, with reference to Fig. 2, a kind of joint, be on embodiment 1 basis, behind the double-layer tube wall that connects tube head 2, be provided with boss 8, be provided with between boss 8 and double-layer tube wall with the tube wall lock ring together and exceed the Flexible clamp 9 on boss 6 planes, connect hoop 6 and be fixed between Flexible clamp 9 and double-layer tube wall, other are identical with embodiment 1.
During use, box cupling 6 is installed on the connection tube head 2 in succession earlier, then with on Flexible clamp 9 folders, because the minimum diameter that connects hoop 6 is less than the maximum outside diameter of Flexible clamp 9 and greater than the maximum outside diameter of boss 8, connecting hoop 6 so just can not come off from connecting tube head 2, make connect hoop 6 can only activity within the limits prescribed, 2 pairs of middle body 1 and tube heads is tight, hoop 6 is rotationally connected, pawl 3 in the middle of making on the body 1 binds round 6 interior ratchets 7 and presses and screw with being connected, so just can guarantee that two pipelines link together, equally another being connected tube head 2 connects, sealing gasket 5 can make two pipelines connect closely, and the first-class equipment of spray that will need then to use is connected on the connection mouth 4 and gets final product.
