Description

Technical Field

[0001] The utility model belongs to the technical field of pump testing, and in particular relates to a convenient quick connector for a pressure sensor. Background Art

[0002] During a pump performance test, pressure sensors are installed on the pump's inlet and outlet test piping to measure the pump's head. The pressure sensor has a threaded connection on one end and a shielded cable for data transmission on the other. The cable is typically 5 meters or longer. When installing the pressure sensor on the inlet and outlet piping, the shielded cable is bent into a loop and rotated along with the pressure sensor. The pressure sensor is then screwed onto the pressure tapping holes on the pump's inlet and outlet test piping, ensuring the threads of the pressure tapping holes are securely connected to the pressure sensor threads.

[0003] Due to the high value of pressure sensors, factories do not install them separately for each inlet and outlet pipeline pump. When the test is completed and other pipelines are switched to test other pumps, the pressure sensor needs to be removed and installed on another test pipeline. Therefore, installing and removing pressure sensors becomes a relatively frequent task during pump testing.

[0004] Since the shielding wire at one end of the pressure sensor is inconvenient to remove from the pressure sensor, when installing or removing the pressure sensor, the shielding wire can only be bent into a ring for easy rotation installation. The shielding wire has a certain hardness and the diameter of the ring after bending is large. Therefore, when installing and removing the pressure sensor, there needs to be enough space around to ensure that the sensor and the shielding wire bent into a ring can rotate freely. In addition, when installing and removing the pressure sensor, when the sensor and the shielding wire are rotated, the ring of the shielding wire is easy to loosen, causing the shielding wire to twist. Over time, it is easy to cause the joint between the shielding wire and the sensor to loosen or break, causing the sensor to not work normally, which brings inconvenience to daily work. Utility Model Content

[0005] The present invention aims to provide a convenient quick-connect connector for pressure sensors, enabling seamless connection between the pressure sensor and the pump's inlet and outlet test lines without rotating the pressure sensor or its connecting shielded wire. This connector effectively addresses the limited installation space for pressure sensors and prevents loosening or breakage of the shielded wire at the sensor connector during installation.

[0006] The utility model is achieved in this way. It is a convenient quick connector for a pressure sensor, comprising: a connector body, one end of the connector body is threadedly installed in a pressure-taking hole on a pipeline, the other end of the connector body is provided with a mounting seat, one end of the mounting seat and the other end of the connector body are covered with threaded sleeves, and the core of the connector body is provided with a connector body through hole along the axial direction; a sealing gasket, the sealing gasket is arranged between the other end of the connector body and the mounting seat, and the center of the sealing gasket is provided with a sealing gasket through hole corresponding to the connector body through hole.

[0007] Preferably, the inner wall of the threaded sleeve is provided with an internal thread with a step, and the other end of the connector body is adapted to the internal thread with a step of the threaded sleeve.

[0008] Preferably, the outer peripheral surface of the threaded sleeve is provided with a square opening.

[0009] Preferably, a transition section is formed between the two ends of the joint body, and square openings are formed at both ends of the transition section.

[0010] Preferably, one end of the mounting seat that cooperates with the threaded sleeve is provided with an external thread, the other end of the mounting seat is provided with a threaded inner hole, the outer peripheral surface of the mounting seat is provided with a square opening, and the core of the mounting seat is provided with a through hole.

[0018] Specifically, the right end of the connector body 1 is threaded and screwed into the pressure tapping holes of the inlet and outlet pipes. The left end of the connector body 1 is a cylindrical section with two steps. The core of the connector body 1 has a Φ6 through-hole, which transmits the liquid pressure to the pressure sensor. The sealing gasket 4 also has a Φ6 through-hole in the middle, which transmits the liquid pressure to the pressure sensor.

[0019] In a further preferred embodiment of the present invention, the other end of the connector body 1 is a cylindrical section with two steps. Square openings are machined on the left and right connecting cylinders of the connector body 1, making it easy to clamp the square openings with a wrench and tighten the connector body 1 into the pressure holes of the inlet and outlet pipes.

[0020] In a further preferred embodiment of the present invention, the inner wall of the threaded sleeve 2 is provided with an internal thread with a step, and the other end of the connector body is adapted to the internal thread with a step of the threaded sleeve.

[0021] Specifically, there is a threaded inner hole in the middle of the threaded sleeve 2, and the bottom is processed into a stepped through hole. The stepped through hole can pass through the cylindrical section with two steps at the left end of the joint body 1 and can clamp the cylindrical section with a larger diameter and one step, and ensure that the joint body 1 does not fall off.

[0022] In a further preferred embodiment of the present invention, the outer circumference of the threaded sleeve is provided with a square opening. The largest outer circle of the threaded sleeve 2 is processed with a square opening for easy clamping with a wrench.

[0023] In a further preferred embodiment of the present invention, a transition section is formed between the two ends of the connector body, and square openings are formed at both ends of the transition section.
