Description

A kind of composite type connector lug
Technical field
The utility model relates to a kind of composite type connector lug.The pipeline mainly applying to all kinds of non-strong corrosive fluid (as diesel oil, gasoline, lubricant oil, petrol engine and Diesel Engine Coolants, water etc., general gas flow pipeline) is connected and seals.
Background technique
At present, connect between hydropneumatic pipeline pipe joint and adopt flared fitting connecting tube, transit joint and flared fitting generally adopt welding procedure to be connected, and need sheath and fastening sleeve to realize being connected and sealing between transit joint with flexible pipe.Flared type jointing adopts face/linear sealing mode, and sealing surface requirement on machining accuracy is high, and form and position tolerance is difficult to ensure, sealing surface is easy to wear, causes leakage; Distance, connecting tube, joint are many, increase risk of leakage.
Prior art is compared, and the beneficial effects of the utility model are:
1, structure is simple, and part is few.
2, easy for installation.
3, good airproof performance.
4, with low cost.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, good airproof performance, and form and position tolerance easily ensures, the simple composite type connector lug of structure.
Technical solution of the present utility model is such, a kind of composite type connector lug, comprises jointing, locking nut, O type circle, air input joint.It is characterized in that between jointing (1) and air input joint (4) affixed by locking nut (2), O type circle (3) is installed between air input joint (4) and jointing (1) seal, air input joint (4) termination external diameter has screw thread and locking nut (2) internal thread to connect, locking nut (2) is stepped shaft, the roundlet of ladder is set to jointing (1) intermediate lands outer bottom root and has annular groove installation O type circle (3), and O type circle (3) external diameter rides over air input joint (4) port inner diameter wall.
Jointing (1) small end head has outside thread.
There is outside thread at air input joint (4) two ends.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of a kind of composite type connector lug of the utility model.
Fig. 2 is the appearance schematic diagram of the composite type connector lug of a kind of compact structure of the utility model.
Reference character: jointing (1), locking nut (2), O type circle (3), air input joint (4).
Embodiment
Most preferred embodiment of the present utility model is such, existing jointing (1) is flared type connecting head, that enlarging jointing is connected between jointing (1) with air input joint (4), the sealing means belonging to line and face seals, and such sealing requirement on machining accuracy is very high, and form and position tolerance is difficult to ensure, sealing surface is easily standby to be dug, distance, connecting tube and joint many, increase risk of leakage.And just reach good sealing effect with O type circle (3) of the present invention.Jointing (1) small end head has screw thread, has circular bosses in the middle of jointing (1).Locking nut (2) has large small stair circle, and there is outside thread at air input joint (4) two ends, and also there is step circle at air input joint (4) middle part, and the large stage circle external diameter that jointing (1) intermediate lands to air input joint (4) is held has the seal groove installing O type circle (3).Affixed by locking nut (2) between jointing (1) and air input joint (4), O type circle (3) is installed between air input joint (4) and jointing (1) seal, air input joint (4) termination external diameter has screw thread and locking nut (2) internal thread to connect, locking nut (2) is stepped shaft, the roundlet of locking nut (2) ladder is set to jointing (1) intermediate lands outer bottom root, jointing (1) inner external diameter has annular groove and install O type circle (3), O type circle (3) external diameter rides over air input joint (4) port inner diameter wall.

Claims (3)

1. a composite type connector lug, comprise jointing (1), locking nut (2), O type circle (3), air input joint (4), it is characterized in that between jointing (1) and air input joint (4) affixed by locking nut (2), O type circle (3) is installed between air input joint (4) and jointing (1) seal, air input joint (4) termination external diameter has screw thread and locking nut (2) internal thread to connect, locking nut (2) is stepped shaft, the roundlet of locking nut (2) ladder is set to jointing (1) intermediate lands outer bottom root, jointing (1) inner external diameter has annular groove and O type circle (3) is installed, O type circle (3) external diameter rides over air input joint (4) port inner diameter wall.
2., according to a kind of composite type connector lug according to claim 1, it is characterized in that jointing (1) small end head has outside thread.
