Have the external screw thread mated with described female thread, the both ends of the surface of described joint all with described box cupling formed shoulder, described external screw thread and
Screw-internal thread fit forms primary sealing area, and the both ends of the surface of described box cupling are secondary sealing area with the circular bead surface of described groove, described
Crossover position between primary sealing area and described secondary sealing area is provided with the 3rd sealing surface, and described 3rd sealing surface includes setting
Putting the cylinder on described groove and the sphere being arranged on described box cupling, described cylinder sphere interference fit, described shoulder is
Reversely shoulder, described secondary sealing area is also equipped with oil leakage monitoring device for oil pipeline.
The main body of described box cupling is cuboid tubular structure.
The angle of described shoulder is-30oTo-10o。
At the bottom of described female thread and externally threaded tooth and tooth top is respectively provided with rounding.
The outer surface of described box cupling and described joint is provided with antirust coat.
It is additionally provided with sealing ring between described joint and described mesospore ring.
Described female thread and external screw thread all use 8 teeth or the round thread of 6 teeth.
Beneficial effects of the present invention: a kind of leakage of oil monitoring type petroleum oil joint that the present invention provides, has three-layer sealed
Face, wherein the 3rd sealing surface is that the sphere interference fit on the cylinder and box cupling being arranged on groove is formed, the mistake of metal/metal
The fit structure that is full of has good sealing effectiveness, and simultaneously by sealing spherical design inside female thread, joint is the closeest
Front cover is not easy to be broken, and extends the service life of joint, and described shoulder is reverse shoulder, remains to keep under tensile load
Higher contact pressure, improves sealing effectiveness, oil leakage monitoring device for oil pipeline, can monitor oil leakage of oil situation, it is to avoid stone
Oil waste；The main body of described box cupling can be cuboid tubular structure, it is ensured that petroleum oil joint stable in placement, is difficult to rolling
Dynamic；On described box cupling on female thread and described joint at the bottom of externally threaded tooth and tooth top has rounding, thread compound can be allowed more preferable
Interstitial flow between form of thread, it is ensured that petroleum oil joint is not susceptible to thread gluing.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the present invention.
Fig. 2 is the enlarged drawing of S portion in Fig. 1.
Fig. 3 is the outline drawing of box cupling.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
As it is shown in figure 1, a kind of leakage of oil monitoring type petroleum oil joint, including the joint 1 of petroleum oil body with for close
Envelope connects the box cupling 2 of joint 1 described in two, and described box cupling 2 axially two ends all symmetries are shaped with female thread, described box cupling 2 inwall
The mesospore ring 3 that middle part is provided with between joint described in two 1, the outer wall of described joint 1 offers and connects described in accommodating
The groove of hoop 2, is provided with the external screw thread mated with described female thread in described groove, the both ends of the surface of described joint 1 are all with described
Box cupling 2 forms shoulder 7, described external screw thread and screw-internal thread fit and forms primary sealing area 4, and the both ends of the surface of described box cupling 2 are with described
The circular bead surface of groove is secondary sealing area 5, and the crossover position between described primary sealing area 4 and described secondary sealing area 5 is arranged
There is the 3rd sealing surface 6, described secondary sealing area 5 is also equipped with oil leakage monitoring device for oil pipeline 8.
It is also equipped with oil leakage monitoring device for oil pipeline 8 on described secondary sealing area 5, petroleum oil joint can be monitored
Leakage of oil situation, it is to avoid oil losses.
As it is shown on figure 3, the main body of described box cupling 1 is cuboid tubular structure, it is ensured that petroleum oil joint is put surely
Fixed, it is difficult to roll.
