The utility model discloses a realize that the technical scheme of its purpose is like: the turtle-back type hydraulic right-angle flange comprises a flange block, wherein a bottom oil port is arranged on the bottom surface of the flange block, a mounting hole which penetrates through the flange block from top to bottom is formed in the top surface of the flange block, a turtle-back-shaped protrusion extending forwards is formed in the top surface of the flange block, a front side oil port is formed in the front side surface of the turtle-back-shaped protrusion and the front side surface of the flange block, a right-angle oil duct which is communicated with the bottom oil port and the front side oil port is formed in the flange block and the turtle-back-shaped protrusion, the turtle-back type hydraulic right-angle flange is characterized in that a boss is arranged at the top of the flange block, the rear. The utility model discloses in, the setting of boss has increased the thickness of flange piece in this position in other words, makes it can satisfy the thickness requirement that sets up the screw thread test socket, and the drilling sets up the screw thread test socket when necessary. Because only the lug boss is locally added, the original thickness of other parts of the flange block is still kept, and the flange block has manufacturing economy. The flange block is directly drilled with a thread test port, and the reliability is high.
In the turtle-back type hydraulic right-angle flange, the central axis of the boss is parallel to the central axis of the turtle-back type protrusion and is in the same vertical plane.
In the turtle-back type hydraulic right-angle flange, the size of the boss in the left-right direction is smaller than that of the boss in the bottom in the left-right direction. Further, the boss is arc-shaped, or the boss is trapezoidal.
In the turtle-back type hydraulic right-angle flange, the rear side face of the flange block is provided with a thread test port communicated with the right-angle oil duct, and the thread test port is located under the boss.
In the turtle-back type hydraulic right-angle flange, the turtle-back-shaped protrusions are formed by semi-cylindrical protrusions located on the top surface of the flange block and quarter spherical protrusions located at the rear parts of the semi-cylindrical protrusions.
In the turtle-back type hydraulic right-angle flange, welding rings which surround the front side oil port and are used for pipeline welding are arranged on the front end face of the turtle-back type protrusion and the front side face of the flange block.
Compared with the prior art, the utility model discloses the boss that sets up at the protruding rear of tortoise-back shape in the flange has increased the thickness of flange piece in this position in other words, makes it can satisfy the thickness requirement that sets up the screw thread test mouth, and the necessary drilling sets up the screw thread test mouth. Because only the lug boss is locally added, the original thickness of other parts of the flange block is still kept, and the flange block has manufacturing economy. The flange block is directly drilled with a thread test port, and the reliability is high.

Detailed Description
The following description of the embodiments refers to the accompanying drawings.
As shown in fig. 1 and fig. 3, the hydraulic right-angle flange is of a turtle-back type, and comprises a flange block 1, wherein a bottom oil port 51 is arranged on the bottom surface of the flange block 1, a mounting hole 14 which penetrates through the flange block 1 up and down is arranged on the top surface, a turtle-back-shaped protrusion 2 which extends forwards is arranged on the top surface 12 of the flange block 1, and the turtle-back-shaped protrusion 2 is composed of a semi-cylindrical protrusion 21 which is arranged on the top surface of the flange block and a quarter spherical protrusion 22 which is arranged at the rear part. Front side oil ports 52 are arranged on the front side faces of the turtle-back-shaped protrusion 2 and the flange block 1, right-angle oil ducts 5 communicating the bottom oil port with the front side oil port are arranged in the flange block 1 and the turtle-back-shaped protrusion 2, and welding rings 23 which surround the front side oil port and are used for pipeline welding are arranged on the front end face of the turtle-back-shaped protrusion 2 and the front side face of the flange block 1. When the flange is welded with the steel pipe, the steel pipe is butted with the welding ring 23 or inserted into the welding ring 23 to be welded with the flange.
The top of the flange block 1 is provided with a boss 3, the rear end face of the boss 3 is flush with the rear side face 11 of the flange block 1, the front end of the boss 3 is integrally connected with the turtle-back-shaped bulge 2, and the central axis of the boss 3 is parallel to the central axis of the turtle-back-shaped bulge 2 and is positioned in the same vertical plane. The dimension of the boss 3 in the left-right direction at the top is smaller than that at the bottom, for example, the boss is circular arc-shaped.
As shown in fig. 2 and fig. 3, a thread test port 4 communicated with the right-angle oil passage 5 is drilled on the rear side surface 11 of the flange block 1, and the thread test port 4 is positioned right below the boss 1.
The shape of the boss 4 may also be such that the boss 3 is trapezoidal, as shown in figure 4.
In the embodiment, the flange block 1, the turtle-back-shaped bulge 2, the boss 3 and the welding ring 23 are all of an integral structure, and are formed by forging and machining during manufacturing. And the turtle-back type hydraulic right-angle flange with the thread test port and the turtle-back type hydraulic right-angle flange without the thread test port are subjected to co-blanking.
