Problems solved by technology

Only when the leakage between the corrugated pipe layers reaches a certain pressure, the leakage can be found, and the leakage of the expansion joint cannot be judged, so the sensitivity of this method is low
In addition, this method can only be used to detect the leakage of multi-layer bellows, and it is only suitable for expansion joints with internal pressure structure.

Embodiment Construction

[0022] The quantitative detection device for external pressure expansion joint leakage is composed of a specially designed liquid accumulation tank (assuming V1=1L, V2=2L, V3=3L, and the diameter of the drain hole can also be different), and a GSM wireless transmitter. When there is no leakage in the expansion joint, the quantitative detection device will not send an early warning signal. When the expansion joint leaks, the working medium flows into the V1 area of ​​the liquid accumulation tank preferentially through the expansion joint drain pipe, and the water immersion sensor or water leakage sensor senses the accumulated water, and the GSM1 wireless transmitter sends out a signal and is discharged through the liquid discharge hole. If the volume is less than the discharge volume of the drain hole, the V1 area of ​​the effusion tank will never be full, indicating a slight leakage of the expansion joint, and the expansion joint can continue to be used without replacement; if ...

Abstract

Disclosed is a quantitative detection device for external pressure expansion joint leakage. Through quantitative detection on the leakage mount of media, in combination with structural characteristics of an external pressure expansion joint, the leakage amount of a non-pressed cavity can be detected in real time, and real-time early warning is provided for overhauling or replacing of the expansion joint.

Description

technical field [0001] The invention belongs to the technical field of urban heat supply, and particularly designs a quantitative detection device that can be used for leakage of external pressure expansion joints. Background technique [0002] Central heating is one of the main infrastructures of urban modernization. It plays an important role in saving energy, improving the environment, and improving people's living standards. Metal bellows expansion joints are one of the key components for thermal compensation in modern heating pipe networks. , has the functions of displacement compensation, vibration and noise reduction and sealing, which directly affects the safety and stability of heating pipelines. If the expansion joint leaks, the pipeline will stop running. Therefore, it is necessary to design an expansion joint with a quantitative leakage detection device, which has the function of leakage detection and alarm. [0003] The current leakage detection technology for...
