A detection device suitable for liquid circuit

Abstract

The invention discloses a detection device suitable for liquid circuits, which is used to solve the problems of low detection accuracy and inconvenient disassembly and assembly of bubble sensors and pipelines existing in the prior art; block, the bottom of the mounting block is provided with a first groove, the inside of the mounting block is located on both sides of the first groove and oppositely provided with two arc-shaped chutes, and the inside of the arc-shaped chute is slidably connected with an arc-shaped fixed arm; the present invention will Put the hose into the first groove and loosen the pull rod, it is very convenient to disassemble the hose to be tested; put the air bubble sensor into the second groove, loosen the limit plate to limit the air bubble sensor in the storage slot, It is very convenient to disassemble and assemble the air bubble sensor; it is convenient to adjust the detection distance between the air bubble sensor and the hose to be tested by using the sliding relationship between the slider and the lateral chute. Using two air bubble sensors can effectively improve the detection accuracy and eliminate external interference .

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a detection device suitable for liquid circuits. Background technique [0002] The acoustic impedance of ultrasonic waves in different propagation media is different, and its acoustic impedance in air and water is very different. Using this characteristic of ultrasonic waves, a bubble sensor for detecting bubbles in pipelines can be designed. [0003] The detection of air bubble sensor is generally non-contact detection. However, only one air bubble sensor is usually used to detect air bubbles in the existing pipeline, and the detection accuracy is low. At the same time, when the water flow in the pipe wall is too fast, it is easy to cause misjudgment by the sensor. In addition, when detecting air bubbles in the pipeline, it is inconvenient to disassemble and assemble the air bubble sensor and the pipeline, and it is inconvenient to perform detection work.

Problems solved by technology

[0004] The purpose of the present invention is to propose a detection device suitable for liquid circuits, which can effectively overcome the defects of low detection accuracy and inconvenient disassembly and assembly of the bubble sensor and pipeline in the prior art; the present invention pulls up the pull rod, Driven by the pull rope, the arc-shaped fixed arms move along the arc-shaped chute and separate from each other, put the hose to be tested into the first groove, and loosen the pull rod, the hose to be tested can be limited to the arc-shaped fixation Between the arm and the first groove, it is very convenient to disassemble and assemble the hose to be tested; put the air bubble sensor into the second groove, loosen the limit plate to limit the air bubble sensor in the storage slot, and disassemble the air bubble sensor very easily Convenient, easy to repair and maintain; use the sliding relationship between the slider and the lateral chute to easily adjust the detection distance between the air bubble sensor and the hose to be tested. At the same time, the use of two air bubble sensors can effectively improve the detection accuracy and eliminate the external interference
