Description

Internal thread adds banding formula tee union

Technical field

The utility model relates to tee union, particularly relates to internal thread and adds banding formula tee union, belongs to the conduit pipeline accessory.

Background technique

Tee union is a kind of conduit pipeline accessory commonly used, is applicable to that lateral connects.The Placement of existing common plastics tee union has two kinds, and is a kind of for being threaded, and in joint, is shaped on internal thread and is connected with the outside thread of water pipe; Will be during construction to the processing of water pipe head, swivel joint in the installation, troublesome poeration; Another kind of employing blanching welding connects; This method is simple to operate, but intensity is lower, is applicable to that generally little water pipe connects.

Summary of the invention

The purpose of the utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of main road water pipe head to process, the banding cooperation; It is laborsaving to construct, and good airproof performance divides the branching pipe internal thread to connect; Easy for installation, and the internal thread that connects convenient disassembly everywhere adds banding formula tee union.

The technological scheme that the utility model internal thread adds banding formula tee union is: comprise the tee union body, the tee union body is divided into upper connection, lower contact and side connector, it is characterized in that said side connector inwall is shaped on internal thread; Respectively be shaped on outside thread at upper and lower joint, the outside thread attaching nut is shaped on casing coupling on the nut; The inwall of casing coupling is installed retainer ring in being tilted in upper and lower inner nosepiece wall, is shaped on platform on the retainer ring; Construction opening retaining ring on platform; The outer wall of opening retaining ring contacts with the inwall of casing coupling, is shaped on the card muscle at the inwall of opening retaining ring, and the card muscle matches with pipe outer wall.

The utility model discloses a kind of internal thread and add banding formula tee union, during installation, earlier the internal thread of side connector and the screw thread rotation of pipe outer wall are tightened; Unclamp the nut of upper and lower joint again, insert water pipe in the upper and lower joint, again fastening nut; When nut is tightened downwards; Inwall in being tilted to of nut casing coupling pushes the outer wall of opening retaining ring downwards, makes the inside banding water pipe of card muscle in the opening retaining ring, and banding is firm.During dismounting, as long as unclamp nut a little, the opening retaining ring is not squeezed, and water pipe can take out easily, installs, dismounting is very convenient, and it is laborsaving to construct.

The utility model internal thread adds banding formula tee union, respectively is shaped on step in the said upper and lower joint, and seal ring is installed on step, and seal ring contacts with the retainer ring lower end.Seal ring has been arranged, guaranteed the sealing effect of retainer ring and joint.Said nut outer wall is shaped on stiffening rib.Stiffening rib has been arranged, has improved nut strength, and when the hand nutting good hand touch.

Description of drawings

Fig. 1 is the structural representation that the utility model internal thread adds banding formula tee union.

Embodiment

The utility model relates to a kind of internal thread and adds banding formula tee union, and is as shown in Figure 1, comprises tee union body 1; The tee union body is divided into upper connection 2, lower contact 3 and side connector 4, it is characterized in that said side connector 4 inwalls are shaped on internal thread 41, respectively are shaped on outside thread 21 at upper and lower joint 2,3; Outside thread attaching nut 6 is shaped on casing coupling 61 on the nut, the inwall 62 of casing coupling is in being tilted to; In upper and lower inner nosepiece wall retainer ring 7 is installed, is shaped on platform 71 on the retainer ring, construction opening retaining ring 8 on platform; The outer wall 81 of opening retaining ring contacts with the inwall 62 of casing coupling 61, is shaped on card muscle 82 at the inwall of opening retaining ring, and the card muscle matches with water pipe 9 outer walls.During installation, earlier the internal thread 41 of side connector 4 is tightened with the screw thread rotation of pipe outer wall, unclamped the nut 6 of upper and lower joint 2,3 again; Insert water pipe in the upper and lower joint; When fastening nut again, nut 6 were tightened downwards, the inwall 62 in being tilted to of nut casing coupling 61 is the outer walls 81 of extruding opening retaining rings 8 downwards; Make the card muscle 82 inside banding water pipes in the opening retaining ring, banding is firm.During dismounting, as long as unclamp nut 6 a little, opening retaining ring 8 is not squeezed, and water pipe can take out easily, installs, dismounting is very convenient, and it is laborsaving to construct.Respectively be shaped on step 22 in the said upper and lower joint 2,3, seal ring 23 is installed on step, seal ring contacts with retainer ring 7 lower ends.Seal ring 23 has been arranged, guaranteed the sealing effect of retainer ring 7 and joint.Said nut 6 outer walls are shaped on stiffening rib 63.Stiffening rib 63 has been arranged, has improved nut 6 intensity, and when the hand nutting good hand touch.
