Description
Technical field
The utility model is related to elastic spandex fiber production fields, and in particular to be based on Free Float Type Steam Trap principle to be a kind of
On-line measuring device.
Background technology
Need to consume a large amount of steam in elastic spandex fiber production process to heat for equipment, when steam with condensed water into
When entering equipment heat exchange, it will seriously affect heat transfer efficiency, increase energy consumption, therefore need to be entered with Free Float Type Steam Trap in producing
Condensed water removes in steam before heater；When steam and formed after heating equipment heat exchange steam and condensing water vapor liquid mixture into
When entering recovery system, a large amount of waste of steam will be generated, increase operating cost, therefore need to be changed with Free Float Type Steam Trap in producing
Only condensed water is discharged for vapor-liquid separation after heat；So whether Free Float Type Steam Trap works normally in production, energy will be affected
The digestion of amount and the increase of operating cost.
A kind of steam trap failure detector and system disclosed in prior art China patent CN 203809843U,
Failure detector includes supersonic detector and warning device, and supersonic detector is mounted on steam trap, and detection is steamed
The vibration frequency that vapour drain valve is sent out sends out alarm signal when vibration frequency is in scheduled frequency range to the warning device
Number.Above-mentioned detection device is limited to：
1. drain valve vibration frequency is influenced by factors such as condensed water flow velocity, water hammers in pipe stress, pipeline, causes ultrasound
Wave accuracy of detection is low, is easy erroneous judgement；
2. vibration frequency signal is easily influenced by environment such as live forceful electric power, is susceptible to deviation；

A kind of thermo-electric plant steam-water pipe drain valve disclosed in prior art China patent CN103016948A is supervised online
Leakage device, the device is by digital temperature sensor, signal picker, communication cable, light cat, optical cable and data processing computer group
At digital temperature sensor uses DS18B20, several numbers arranged in same drain valve downstream drain water piping external circumferential
Temperature sensor shares a digital temperature signal collection device, according to the data and its change rate of drain valve downstream wall surface temperature,
Fuzzy diagnosis is carried out to trap leaking grade using the principle of Fuzzy Pattern Recognition.Above-mentioned online prison leakage, which is limited to, includes：
1. main steam transfer pipeline is because keeping the temperature a small amount of condensed water of bad formation, temperature-resistant, the condensed water of drain valve discharge
Temperature is identical as supervisor's vapor (steam) temperature, then can not detect whether drain valve leaks；
2. field signal acquisition is easily affected by environment, causes trueness error, is easy erroneous judgement；
3. after steam enters heating equipment heat exchange, when heating equipment only absorbs the latent heat of vaporization of steam, heating equipment is discharged
The same vapor (steam) temperature of condensate temperature, hydrophobic valve pipeline temperature outside can not detect difference；
Certainly, also visor observation in the prior art, is installed on pipeline in glass mirror observation pipeline after drain valve
Whether condensed water carries steam, but find in actual use the easy fouling of glass mirror, it is fuzzy be not easy to judge drain valve state and
And it is easily broken and causes production accident.
