Abstract
A tightly-hooped type three-way connector with outer threads comprises a three-way connector body which is divided into an upper connector, a lower connector and a lateral connector. The three-way connector is characterized in that outer threads A are manufactured on the outer wall of the lateral connector, outer threads B are manufactured on the outer wall of the upper connector, outer threads C are manufactured on the outer wall of the lower connector, and the outer threads B and the outer threads C are respectively connected with a nut. A press ring is respectively installed in the upper connector and the lower connector, an opening fastening ring is installed one each press ring, the outer wall of each opening fastening ring is a conical face inclined inwards, and clamping teeth are manufactured on the inner wall of each opening fastening ring. A shrinking section is manufactured on each nut, the inner wall of each shrinking section is a conical face inclined inwards, and the inner wall of each shrinking section is matched with the outer wall of each opening fastening ring. Steps are manufactured in the upper connector and the lower connector, sealing rings are installed on the steps and contacted with the lower ends of the press rings, and reinforcing ribs are manufactured on the outer walls of the nuts.
Description
Technical field
The utility model relates to tee union, particularly relates to outside 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 a kind of for being threaded, the system internal thread is connected with the outside thread of water pipe in joint; 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 to process, and is easy for installation, quick; Banding is firm; Good airproof performance, branch road water pipe outside thread connects, and the outside thread that connects convenient disassembly adds banding formula tee union.
The technological scheme that the utility model outside 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 the outer wall of said side connector is shaped on outside thread A; Be shaped on outside thread B at the upper connection outer wall, the lower contact outer wall is shaped on outside thread C, outside thread B, each attaching nut of C; In upper and lower joint, retainer ring is installed, construction opening retaining ring on the retainer ring, the outer wall of opening retaining ring are the conical surface in being tilted to; The inwall of opening retaining ring is shaped on latch, on nut, is shaped on casing coupling, and the inwall of casing coupling is the conical surface in being tilted to; The inwall of casing coupling matches with the outer wall of opening retaining ring, is shaped on step in the said upper and lower joint, and seal ring is installed on step; Seal ring contacts with the retainer ring lower end, and said nut outer wall is shaped on stiffening rib.
The utility model discloses a kind of outside thread and add banding formula tee union, during installation, earlier the outside thread A of side connector and the internal thread rotation of branch's pipe inner wall are tightened; Unclamp the nut of upper and lower joint again, the opening of opening retaining ring is unclamped, insert water pipe in the upper and lower joint then; Downward fastening nut, the casing coupling of nut are when being rotated down, and the conical surface of inwall pushes the conical surface of opening retaining ring outer wall; Make the inside banding water pipe of latch of opening retaining ring, banding is firm.During dismounting, upwards unclamp nut, the conical surface of casing coupling inwall does not push the conical surface of opening retaining ring outer wall, and the opening retaining ring does not push the outer wall of water pipe, and water pipe can take out easily, installs, dismounting is very convenient, and it is laborsaving to construct.Seal ring has been arranged, has guaranteed the sealing effect of retainer ring and joint, stiffening rib has been arranged, the raising nut strength, and when the hand nutting good hand touch.
Description of drawings
Fig. 1 is the structural representation that the utility model outside thread adds banding formula tee union.
Embodiment
The utility model relates to a kind of outside 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 the outer wall of said side connector 4 is shaped on outside thread A41, is shaped on outside thread B21 at upper connection 2 outer walls; Lower contact 3 outer walls are shaped on outside thread C31, and outside thread B, each attaching nut 5,6 of C install retainer ring 22,32 in upper and lower joint; The construction opening retaining ring 23,33 on the retainer ring, and the outer wall 24,34 of opening retaining ring is the conical surface in being tilted to, and the inwall of opening retaining ring is shaped on latch 25,35; On nut 5,6, be shaped on casing coupling 51,61, the inwall 52,62 of casing coupling is the conical surface in being tilted to, and the inwall 52,62 of casing coupling 51,61 matches with the outer wall 24,34 of opening retaining ring 23,33; Be shaped on step 26,36 in the said upper and lower joint 2,3; Seal ring 27,37 is installed on step, and seal ring contacts with retainer ring 22,32 lower ends, and said nut 5,6 outer walls are shaped on stiffening rib 53,63.During installation, earlier the outside thread A41 of side connector 4 and the internal thread rotation of branch's pipe inner wall are tightened, unclamp the nut 5,6 of upper and lower joint 2,3 again; The opening of opening retaining ring 23,33 is unclamped, insert water pipe in the upper and lower joint then, downwards fastening nut; The casing coupling 51,61 of nut is when being rotated down; The conical surface of inwall 52,62 pushes the conical surface of opening retaining ring outer wall 24,34, makes latch 25, the 35 inside banding water pipes of opening retaining ring, and banding is firm.During dismounting, upwards unclamp nut 5,6, the conical surface of casing coupling 51,61 inwalls 52,62 does not push the conical surface of opening retaining ring 23,33 outer walls 24,34; The opening retaining ring does not push the outer wall of water pipe; Water pipe can take out easily, installs, dismounting is very convenient, and it is laborsaving to construct.Seal ring 27,37 has been arranged, has guaranteed the sealing effect of retainer ring 22,32 and joint, stiffening rib 53,63 has been arranged, raising nut 5,6 intensity, and when the hand nutting good hand touch.
