Abstract
The utility model discloses a movable connection for connections of rigid pipe and rigid pipe, rigid pipe and hose pipe, hose pipe and hose pipe. The movable connection is that a conical core is positioned on one connector, a conical sleeve is positioned on the other connector, and sealing fillers are filled between the conical sleeve and the conical core when connecting. The two connectors are fastened by a fastening connector to realize seal and connection.
Description
The utility model relates to a kind of loose joint of being connected between hard tube and hard tube, hard tube and flexible pipe or flexible pipe and the flexible pipe of being used for.
Existing hard tube connects and can not be used for being connected with flexible pipe with loose joint, and also exists the shortcoming of joint sealing difference in hard tube connects.The many employings of flexible pipe binding at a hard tube outer wall, are tightened fixing with anchor clamps or iron wire etc. hose proof then.Also have at the flexible pipe head and make fixing joint, link.Existing these technology exist and link inconvenience; Make difficulty; Connect the shortcoming that sealing is bad and connection part intensity is relatively poor.
The utility model provides a kind of and can be used for being connected between hard tube and hard tube, hard tube and flexible pipe, flexible pipe and flexible pipe, and can overcome the loose joint of prior art deficiency.
The utility model is made up of two connecting bodys and a fastening connection piece, and the awl core is arranged on one of them connecting body, on another connecting body tapered sleeve is arranged.When connecting, the awl core matches with tapered sleeve, is lined with stuffing box packing between awl core and tapered sleeve.The stuffing box packing that serves as a contrast can be the sealing gasket of sheet when hard tube is connected with hard tube, better then be the liner of one section tubulose; When flexible pipe and flexible pipe or flexible pipe and hard tube linked, stuffing box packing was the part of the flexible pipe that is bonded.Two connecting bodys are fixed with fastening connection piece.Under the fastening connection piece effect, awl core and tapered sleeve will be bored the stuffing box packing jam-packed that serves as a contrast in core and the tapered sleeve along the axial relative movement of pipe, realize sealing and the effect that is connected.The practical application test shows that best sealing effect is arranged when the cone angle of awl core and tapered sleeve equals 30-60 °.
Adopt difform connecting body, or adopt different fastening connection pieces can constitute different instances of the present utility model.
Advantage of the present utility model is
1, union is simple for production, easy processing;
2, can link hard tube or flexible pipe easily, particularly when flexible pipe connects, need not make the flexible pipe and the liner of belt lacing;
3, can carry out demolition and replacement easily;
4, sealing effect is fabulous, and connection part intensity is higher, and is safe and reliable.
Accompanying drawing provides several example of the present utility model, and wherein accompanying drawing 1 can be used as Figure of abstract.
Below in conjunction with the accompanying drawing example, do further to explain orally.
Fig. 1 is first kind of example of the present utility model.Loose joint is to be made of connecting body 1, connecting body 2, fastening connection piece 10 as seen from the figure.Awl core 5 is wherein arranged on connecting body 1, flanged structure 8 is arranged at the rear portion of awl core 5.Fastening connection piece 10 is upper shields, and its anterior internal thread 12 matches with outside thread 9 on the connecting body 2 head outer surfaces, and tapered sleeve 6 is arranged on connecting body 2, is lined with stuffing box packing 7 between awl core 5, tapered sleeve 6.In this example, actual stuffing box packing is the part of the flexible pipe 13 that is bonded.The port lid edge 14 at upper shield 10 rear portions is stuck in the outside of the flange 8 at awl core 5 rear portions, and under threaded function with connecting body 1 and 2 and stuffing box packing 7 clamp, realize sealing and the purpose that links, have screw thread 3 to be connected on the connecting body 1 with hard tube.
An exemplary embodiments of the present utility model is shown structure for Fig. 1, and wherein tapered sleeve is 60 ° of cone angles with the awl core, and awl core segment length is 8 millimeters, and the tapered sleeve partial-length is 8 millimeters, and caliber is φ 1/2 ".
Fig. 2 is an another kind of form of the present utility model.This example structure with Fig. 1 basically is identical, and difference only is that flanged structure 11 is arranged on the connecting body 2, and screw thread 9 is arranged on the outer surface at the awl core rear portion of connecting body 1, and the port lid edge 14 of fastening connection piece 10 is stuck in the outside of flange 11.
Fig. 3 is that hard tube connects the example of loose joint, and its structure is with shown in Figure 1 identical.And the screw thread 19 that is connected with hard tube is arranged on connecting body 2.Stuffing box packing 7 is the tubular gasket of usefulness plastics, aluminium, red copper, asbestos or rubber system in this example.
Fig. 4 is another structure of the present utility model.Flange 16 and 17 are arranged on connecting body 1.Flange 15 is arranged on the connecting body 2, and fastening connection piece is bolt 10 and nut 18, is connected with 21 by flange hole 4.1 is connected with flange 17 with the hard tube (not drawing among this figure) of other end.
Fig. 5 is the example that two flexible pipes link.Wherein connecting body 1 is the structure of one flanged 16 two ends awl core 5; Connecting body 2 is flanged 15, and its fastening connection piece is a bolt 10.
Be to strengthen sealing effect, can on the awl core of above-mentioned example or tapered sleeve, make seal groove.
