Abstract
The utility model discloses a female threaded union, comprising a left threaded joint, a right threaded joint and an octagonal nut for connecting and locking the left threaded joint and the right threaded joint, wherein a screw thread is formed on the inner wall of the left threaded joint, and a sealing ring is embedded on one side of the left threaded joint contacting the right threaded joint. Because the screw thread is formed on the inner wall of the left threaded joint of the utility model, a pipe is connected conveniently and quickly; and because the sealing ring is embedded in the left threaded joint, the damage to the sealing ring is reduced when rotating the nut in order to connect the pipe, thus improving a sealing property.
Description
Technical field
The utility model belongs to the pipe joint field, is specifically related to a kind of internal thread union.
Background technique
Union is as a kind of connection pipe fitting, and the pipeline that is widely used in feedwater piping, gas pipeline or the like a plurality of industries connects.Union is made up of three parts; A special octagon nut and two special inipples, inipple is used for the two ends pipe of connecting tube, and middle octagon nut is equivalent to a pipe collar two ends pipe is coupled together; Movement pipeline and separately not like this with two pipelines, easy access.Union is prone to the sealing gasket in the union is revolved wound when the swivel nut connecting tube, causes the union of pipeline to leak and need reinstall, and wastes time and energy.
The model utility content
The technical problem that the utility model will solve provides a kind of internal thread union of simple in structure, good sealing effect.
For solving the problems of the technologies described above, the technological scheme of the utility model is:
A kind of internal thread union; The octagon nut that comprises left hand thread joint, right-hand thread joint and connection and locking left hand thread joint and right-hand thread joint; It is characterized in that: the inwall of said left hand thread joint is provided with screw thread, and the contacted side of said left hand thread joint and right-hand thread joint is embedded with seal ring.
Take above technological scheme; The beneficial effect that the utlity model has is: the left hand thread inner nosepiece wall of a kind of internal thread union of the utility model is provided with screw thread; Convenient and swift when connecting tube; Seal ring is embedded in the left hand thread joint, can reduce when the connecting tube swivel nut the damage of seal ring, has improved the sealability of union.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of a kind of internal thread union of the utility model.
Embodiment
As shown in Figure 1; A kind of internal thread union; Comprise left hand thread joint 2, right-hand thread joint 4 and the octagon nut 3 that connects and lock left hand thread joint 2 and right-hand thread joint 4; The inwall of said left hand thread joint 2 is provided with screw thread 1, and said left hand thread joint 2 is embedded with seal ring with right-hand thread joint 4 contacted sides.Left hand thread joint 2 inwalls of the utility model are provided with screw thread 1, and are convenient and swift when connecting tube, and seal ring is embedded in the left hand thread joint 2, can reduce when the connecting tube swivel nut the damage of seal ring, improved sealability.
