A drainage component is provided on the right side of the top of the box cover. The drainage component includes a pressure relief pipe, a partition, a pressure relief hole, a ball core, a spring, an adjustment hole, an adjustment pipe, a connecting ring, a drainage pipe, and a connecting platform. The pressure relief pipe is fixed to the right side of the top of the box cover. A partition is fixed inside the pressure relief pipe. A pressure relief hole is provided on the surface of the partition. A ball core is provided at the top of the pressure relief hole. A spring is installed at the top of the ball core.

The bottom end of the adjustment pipe extends into the inside of the pressure relief pipe. A connecting platform is fixed at the bottom end of the adjustment pipe. The bottom end of the connecting platform is fixedly connected to the top of the spring.

[0006] As a further technical solution of this utility model, a drive platform is fixed at the center of the bottom end of the connecting pipe. The drive platform has a drive hole inside, and a drive bolt is threaded into the drive hole. The top end of the drive bolt extends into the interior of the connecting pipe. A knob is fixed at the bottom end of the drive bolt, and an isolation cover is movably installed at the top end of the drive bolt.

[0007] As a further technical solution of this utility model, a guide rod is provided on the left side inside the isolation cover, and the bottom end of the guide rod is fixedly connected to the bottom end inside the connecting pipe.

[0008] As a further technical solution of this utility model, a detection platform is fixed on the left side of the top of the box cover, a pressure transmitter is installed on the top of the detection platform, and the bottom of the pressure transmitter extends into the interior of the monitoring box.

[0009] As a further technical solution of this utility model, a positioning shaft is installed inside the monitoring box, a rotating wheel is movably installed on the outer side of the positioning shaft, and a lever is fixed on the outer side wall of the rotating wheel.

[0010] As a further technical solution of this utility model, several levers are fixed on the outer side wall of the rotating wheel, and the several levers are distributed in a ring.

[0011] As a further technical solution of this utility model, an observation platform is fixed on the right side of the monitoring box, an installation ring is provided on the inner side of the observation platform, an observation window is fixed on the right side of the installation ring, and a transparent plate is fixed inside the installation ring.

[0012] As a further technical solution of this utility model, the adjustment hole is provided with an internal thread, and the surface of the adjustment tube is provided with an external thread.

[0013] The beneficial effects of this utility model are as follows: This utility model can detect the pressure inside the connecting pipe, solving the problem that traditional pressure monitoring devices do not have pressure relief protection and have poor pressure regulation effect when the pressure inside the connecting pipe and monitoring box is too high.

[0014] By installing a pressure relief pipe located at the top of the cover, if the pressure inside the connecting pipe and the monitoring box is too high, the internal medium pushes the ball core upward and separates it from the pressure relief hole. The medium inside the connecting pipe can then enter the regulating pipe through the pressure relief hole and finally flow to the outside through the drainage pipe. This can assist in pressure relief protection and realize the pressure relief protection function when the pressure monitoring device is in use.

[0015] By setting an isolation cover, which is located inside the connecting pipe, if the drive bolt is rotated, the drive bolt and the drive hole threaded together, the isolation cover can be pushed up. When the isolation cover is connected to the monitoring box, the monitoring box and the connecting pipe can be isolated by the isolation cover. The monitoring of the entire connecting pipe can be temporarily shut down without turning off the pressure transmitter, thus realizing the isolation control function inside the pressure monitoring device.

[0016] The device is equipped with a lever and an observation window. The lever is located on the outside of the rotating wheel. As the medium flows inside the connecting pipe, the flowing medium impacts the lever, which drives the rotating wheel and the lever to rotate. Through the observation window on the side of the monitoring box, the rotation of the lever inside the monitoring box can be observed, which helps to understand the flow state of the medium inside the connecting pipe. This realizes the auxiliary observation function of the pressure monitoring device during use. Attached Figure Description

[0024] Specifically, such as Figure 1 and Figure 2As shown, during use, the pressure pipeline to be tested is assembled with the left and right sides of the connecting pipe 1 respectively. When the drive bolt 4 is rotated by the knob 5, the drive bolt 4 and the drive hole 3 are threaded together, which can push the isolation cover 6 to move up and down inside the connecting pipe 1. The guide rod 7 is used to assist in guiding the movement of the isolation cover 6. When the isolation cover 6 moves up and connects with the bottom opening of the monitoring box 8, it can assist in the isolation operation between the monitoring box 8 and the connecting pipe 1.

[0028] Specifically, such as Figure 1 and Figure 4As shown, during use, if the pressure of the medium inside the connecting pipe 1 is high, when the ball core 22 is pushed upward against the pressure of the spring 23, part of the medium inside the connecting pipe 1 can be drained to the outside through the pressure relief hole 21, the regulating pipe 25, and the drainage pipe 27 for pressure relief. When the regulating pipe 25 is rotated, the regulating pipe 25 and the regulating hole 24 are threaded together. At the same time, PTFE tape is wrapped around the connection between the regulating pipe 25 and the regulating hole 24 to improve the sealing. The regulating pipe 25 can be moved up and down. With the help of the connecting platform 28, the spring 23 can be compressed to adjust the pressure applied by the spring 23 to the ball core 22, thus assisting in adjusting the pressure required for pressure relief.
