Method and system for detecting leakage of drain valve

Abstract

The present invention discloses a method and a system for detecting leakage of a drain valve, wherein the method comprises the steps as follows: an inductor reads work parameters of an upstream pipeline of the drain valve and transmits the read work parameters and an inductor identifier to a fault identification unit; the fault identification unit identifies the received work parameters, so as to determine a work state of the drain valve at present; and if the drain valve is in a fault state at present, the fault identification unit transmits fault state information and the corresponding inductor identifier to a host computer, so that the host computer performs display. The method of the present invention can detect the work state of the drain valve in real time, and can timely and effectively discover the problem of the drain valve during a use process, thereby saving energy, and ensuring production safety and product quality.

Description

technical field [0001] The invention relates to the field of automatic detection, in particular to a leak detection method and system for a steam trap. Background technique [0002] Steam trap is an automatic valve used on steam heating equipment and steam pipelines, which can automatically remove condensed water, air and other non-condensable gases in steam using equipment and pipelines, and can prevent steam leakage. The performance of the steam trap plays a vital role in the normal operation of the steam system, the improvement of the thermal efficiency of steam-using equipment and the rational use of energy. Commonly used steam traps are: mechanical traps (representative products include inverted bucket type and float type), thermodynamic traps (representative products include disc type, pulse type and labyrinth type) and thermostatic type traps (Representative products include bimetal sheet type and bellows type). At present, there are about 4 million steam traps in u...

AI Technical Summary

Problems solved by technology

At present, there are about 4 million steam traps in use in China, but nearly 80% of the steam traps are in poor working condition: some steam traps cannot be closed, causing steam leakage, unable to ensure stable pressure and temperature, and increasing the pressure of the condensate pipe. The working performance of other equipment will cause erosion to the equipment, etc.; some traps cannot be opened, resulting in water accumulation, incorrect temperature control, damage to product quality, reduced heat output, etc., and in serious cases, "water hammer" will occur due to water in the steam pipe "Phenomenon, which poses a threat to safe production

[0003] However, at present, steam traps have been installed and ignored for a long time in China, and most of the management methods can only judge whether the trap is good or bad through regular inspection of the trap, manual observation or sound detection. Obviously, this method cannot be timely and effective. It is found that there are problems in the use of steam traps, which seriously affect the quality of product processing
