Wherein, fig. 1 and fig. 2 respectively show the structure schematic diagram of the pressure measuring device of the present invention at two different positions.

As shown in fig. 1 and 2, an embodiment of the present invention provides a pressure measuring device 100. The pressure measurement device 100 generally includes a device body 102 and a diverter spool 104.

When the reversing valve core 104 is reversed to different positions, pressure signals of different positions can be collected and transmitted to the pressure gauge interface 106 through the connecting channel 114 in the reversing valve core 104, and pressure information is displayed through the pressure gauge 206 connected to the pressure gauge interface 106. The device can display the pressure of different pressure measuring points by directly operating the reversing valve core without dismounting the pressure gauge and the pressure measuring joint.

Therefore, in the using process, pressure measurement can be carried out on each point to be measured only by connecting a pressure gauge 206 into the pressure gauge interface 106 and connecting the points to be measured scattered at each position of the working machine into the pressure measuring point interface 108 and adjusting the position of the reversing valve core 104.

Specifically, when the pressure measurement device 100 has performed a pressure measurement operation, the diverter valve spool 104 may be moved such that the second passage 112 communicates with the pressure relief passage 118 via the connecting passage 114, thereby relieving pressure via the pressure relief interface 116.

As shown in fig. 1, the position of the diverter spool 104 relative to the device body 102 is shown in a pressure relief condition. At this time, the pressure measuring device 100 has completed the pressure measurement, and the pressure gauge 206 performs pressure relief via the pressure relief port 116 successively via the pipe, the pressure gauge port 106, the second passage 112, the connection passage 114, and the pressure relief passage 118. In the process, the other first passages 110 are blocked by the direction change spool 104.

As shown in fig. 2, a schematic diagram of the diverter spool 104 is shown in a pressure sensing state at one of the pressure sensing points. At this time, in fig. 2, the 2 nd pressure measurement point port 108 from the left side sequentially passes through the first channel 110, the connection channel 114, the second channel 112, and the pressure gauge port 106, and is connected to the pressure gauge 206 by a pipeline to measure pressure.

In other words, the marker point 128 serves to indicate the access of each pressure measurement point interface 108. That is, the operator can know the connection between the connecting channel 114 and each first channel 110 inside the direction switch spool 104 by simply observing the alignment of each mark point 128 and the indicator mark 130. Therefore, the interface alignment device can be convenient for operators to carry out simple operation and interface alignment conveniently.

For example, in the embodiment shown in fig. 1, the indicator mark 130 is aligned with the mark point 128 of the pressure relief interface 116, and then the entire pressure relief channel is now open, and a pressure relief operation may be performed; for another example, in the embodiment shown in fig. 2, the indication mark 130 is aligned with one of the mark points 128, which indicates that the entire pressure measuring channel of the corresponding pressure measuring point interface 108 is connected, and the pressure measuring operation may be performed.
