Abstract

The invention relates to the technical field of power assembly test, and discloses a leak-proof device capable of rapidly replacing a liquid temperature measurement sensor. The device comprises a self-sealing joint; a containing cavity is formed in the self-sealing connector, one end of the self-sealing connector is an opening communicated with the containing cavity, and a liquid circulation hole is formed in the surface of the self-sealing connector. The liquid circulation hole is communicated with the accommodating cavity; a spring is arranged in the containing cavity, one end of the spring abuts against the closed end of the self-sealing connector, and the other end of the spring is connected with a sealing cap. An O-shaped ring is further fixedly arranged in the containing cavity, wherein the inner diameter of the O-shaped ring is smaller than the outer diameter of the outer end of the sealing cap, and the outer end of the sealing cap abuts against the O-shaped ring under the action of the spring. The invention further discloses a mounting structure and a using method of the leakage-proof device for quickly replacing the liquid temperature measurement sensor. According to the leak-proof device for quickly replacing the liquid temperature measurement sensor and the mounting structure and the use method thereof, operation and maintenance personnel can conveniently replace the sensor for measuring high-temperature liquid on line, and the risk of liquid leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of powertrain testing and testing, in particular to a leakage prevention device for quickly replacing a liquid temperature measuring sensor, an installation structure and a use method thereof. Background technique [0002] In the powertrain test, it is necessary to install some temperature sensors on the circulating water, lubricating oil and other pipelines for temperature monitoring. However, in the actual test development process, due to the failure of the temperature sensor itself, it needs to be inspected and replaced. Once these measurement sensors need to be replaced, most of the peripheral control equipment must be turned off, waiting for the liquid in the test equipment pipeline to cool down and release pressure. But often in some special tests, once the test is suspended for too long, it will lead to the failure of the test. In order to improve the test efficiency and reduce losses, the operator n...
