The integrated testing device in the prior art, especially for superimposed hydraulic test manifolds with diameters of DN6 and DN10, cannot meet the requirement of arranging all the pressure measuring points on the front of the manifold due to structural limitations. The pressure measuring ports are scattered and the operation is complicated. When debugging the hydraulic manifold, it is not easy to operate, and it is very inconvenient.

Figure 1 shows the three-dimensional structure of the pressure measurement integrated block in the prior art. Since the auxiliary test port 3 and the pressure measurement channel 4 adopt an orthogonal connection channel 5, the main test port and the auxiliary test port can only be set on the opposite side, and cannot be set. On the same side, it brings great inconvenience to production and maintenance.

Fig. 2 shows the three-dimensional structure of the pressure measurement integrated block of the present invention, including the integrated block 1, the pressure measurement channel 4, and the test port, and the main test port 2, the pressure measurement channel 4 and the auxiliary test port 3 are set on the integrated block 1 , the main test port 2 is communicated with the pressure measurement channel 4, and the auxiliary test port 3 is communicated with the pressure measurement channel 4; the main test port 1 and the auxiliary test port 3 are arranged on the same side of the integrated block 1, A non-orthogonal connection channel 5 is set between the secondary test port 3 and the pressure measurement channel 4 .

The angle between the axis of the connecting channel 5 and the X-axis and Y-axis in the horizontal direction of the integrated block 1 is 0-15°. the

The composite angle between the axis of the connecting channel 5 and the X-axis or Y-axis in the horizontal direction of the integrated block 1 is 0-15°.
