The utility model discloses a prevent sealing washer three way connection that drops, including the direct pipe of interior line, seal groove, protruding, the hexagonal cutting ferrule of seal groove card, the direct pipe of outer line, be equipped with the seal groove on the direct pipe both ends face of interior line respectively, it is protruding to be equipped with the seal groove card in the seal groove respectively, the protruding cross -section of seal groove card is semi -circular, the direct pipe middle part of interior line is connected with the direct pipe of outer line perpendicularly, the direct pipe of outer line is close to the junction with the direct pipe of interior line and is equipped with the hexagon cutting ferrule respectively. The utility model discloses a with protruding with establishing the seal groove card in the seal groove, make the sealing washer not drop in the installation, guarantee that the kneck leakproofness is good.
Description
[technical field]
The utility model relates to the technical field, particularly a kind of anti-seal circle that pipeline connects and to drop the technical field of tee union.
[background technique]
Tee union is the one of pipe fitting, its Connecting format is exactly generally direct by threeway and steel pipe butt welding, just occurred being threaded tee union because the method operation aided process too complex is not easy to again dismounting afterwards, screw thread tee union is more conveniently threaded relative to common welding tee jiont treatment and in order to prevent the fluid leakage of joint generally all can be equipped with seal groove at tee union end face and be equipped with seal ring but seal ring often easily drops and causes the inconvenience of installment work in installation process.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of anti-seal circle and to drop tee union, seal ring can be made not drop in installation process, ensures that jointing sealing is good.
For achieving the above object, the utility model proposes a kind of anti-seal circle to drop tee union, comprise interior line straight-through tube, seal groove, seal groove card convex, hexagonal cutting ferrule, outer line straight-through tube, described interior line straight-through tube both ends of the surface are respectively equipped with seal groove, seal groove card convex is respectively equipped with in described seal groove, described seal groove card convex cross section is semicircle, vertically be connected with outer line straight-through tube in the middle part of described interior line straight-through tube, described outer line straight-through tube and interior line straight-through tube are respectively equipped with Hexagon cutting ferrule near joint.
As preferably, described interior line straight-through tube perforation two end part are respectively equipped with internal thread.
As preferably, described outer line straight-through tube outer surface is provided with two sections of outside threads, and be respectively screw thread, lower screw thread, upper screw thread is equipped with nut, pad.
As preferably, described interior line straight-through tube two ends outer edge is respectively equipped with 45 degree of chamferings.
As preferably, described outer line leads directly to pipe end sideline and is provided with 45 degree of chamferings.
As preferably, described hexagonal cutting ferrule cross section outer edge institute formed shape is regular hexagon.
As preferably, in described seal groove, be equipped with elastic seal ring.
The beneficial effects of the utility model: the utility model, by adding seal groove card convex in seal groove, makes seal ring not drop in installation process, ensure that jointing sealing is good.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is that a kind of anti-seal circle of the utility model drops the master of tee union depending on partly cuing open figure;
Fig. 2 is that a kind of anti-seal circle of the utility model drops the seal groove enlarged view of tee union;
Fig. 3 is A-A sectional drawing in Fig. 1.
In figure: line straight-through tube, 11-seal groove, 111-seal groove card convex, 2-outer line straight-through tube, 3-Hexagon cutting ferrule in 1-.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of anti-seal circle of the utility model drops tee union, comprise interior line straight-through tube 1, seal groove 11, seal groove card convex 111, Hexagon cutting ferrule 3, outer line straight-through tube 2, described interior line straight-through tube 1 both ends of the surface are respectively equipped with seal groove 11, seal groove card convex 111 is respectively equipped with in described seal groove 11, described seal groove card convex 111 cross section is semicircle, vertically be connected with outer line straight-through tube 2 in the middle part of described interior line straight-through tube 1, described outer line straight-through tube 2 is respectively equipped with Hexagon cutting ferrule 3 with interior line straight-through tube 1 near joint.Described interior line straight-through tube 1 two end part of boring a hole are respectively equipped with internal thread.Described outer line straight-through tube 2 outer surface is provided with two sections of outside threads, and be respectively screw thread, lower screw thread, upper screw thread is equipped with nut, pad.Described interior line straight-through tube 1 two ends outer edge is respectively equipped with 45 degree of chamferings.Described outer line straight-through tube 2 end sideline is provided with 45 degree of chamferings.Described Hexagon cutting ferrule 3 cross section outer edge institute formed shape is regular hexagon.Elastic seal ring is equipped in described seal groove 11.
A kind of anti-seal circle of the utility model drops tee union, by adding seal groove card convex in seal groove, seal ring not being dropped in installation process, ensureing that jointing sealing is good.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
