A kind of compressed air moisture monitoring device
The utility model relates to oxygenerator non-compressed air moisture monitoring device technical fields, it particularly relates to a kind of
Compressed air moisture monitoring device.
Compressed air before entering oxygenerator host causes if leading portion cleaning equipment failure or treatment effect are bad
Make water impurity be directly entered absorption tower of oxygen erator with air to be caused to be poisoned by molecular sieve absorption, analytic ability can be badly damaged, system
Oxygen amount and oxygen purity processed can be also greatly reduced, and after certain service life, not can guarantee capacity requirements.And molecular sieve is had to scrap more
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of compressed air moisture monitoring device,
The above-mentioned deficiency of the prior art can be overcome.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of compressed air moisture monitoring device, including air accumulator, one end of the bottom connection threeway of the air accumulator, institute
The other both ends for stating threeway are separately connected normally closed blowdown valve and normally opened maintenance valve, and the normally opened maintenance valve is connected by filter
It is connected to liquid-level switch, the liquid-level switch is connected with PLC programmable controller.
Further, the filter is y-type filter.
Further, the liquid-level switch is VP01E photoelectric liquid-level switch.
The utility model has the beneficial effects that the utility model leads to the gas of oxygenerator using liquid-level switch detection air accumulator
In whether contain moisture, touch liquid water in probe positions, it is programmable towards PLC to issue digital signal for photosignal transformation
Controller, PLC programmable controller issue sound-light alarm and operator are reminded to pay attention to.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of compressed air moisture monitoring device according to the utility model embodiment；
Fig. 2 is that the connection according to the utility model embodiment between liquid-level switch and PLC programmable controller is shown
It is intended to；
In figure: 1, air accumulator；2, normally closed blowdown valve；3, normally opened maintenance valve；4, filter；5, liquid-level switch；6, PLC can
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, a kind of compressed air moisture monitoring device according to the utility model embodiment, including storage
Gas tank 1, one end of the bottom connection threeway of the air accumulator 1, the other both ends of the threeway are separately connected normally closed 2 He of blowdown valve
Normally opened maintenance valve 3, the normally opened maintenance valve 3 are connected with liquid-level switch 5 by filter 4, and the liquid-level switch 5 connects
There is PLC programmable controller 6.
In one embodiment, the filter 4 is y-type filter.
In one embodiment, the liquid-level switch 5 is VP01E photoelectric liquid-level switch.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
According to a kind of compressed air moisture monitoring device described in the utility model, when event occurs for compressed air cleaning equipment
When barrier or treatment effect are bad, water impurity is directly entered air accumulator with air, and with the cooling of temperature, pressure increases, and water steams
Airsetting is formed to be attached on air accumulator tank skin for liquid water, and with increasing for liquid water, tank skin water drippage is enriched in air accumulator bottom
Portion, into bottom blow-down mouth threeway position, VP01E photoelectric liquid-level switch probe positions touch liquid water, and photosignal changes,
It issues digital signal and leads to PLC programmable controller, PLC programmable controller starts timing after receiving signal, to prevent from judging by accident
It is disconnected, sound-light alarm is issued after needing continuous acquisition to signal 5min, operator is reminded to pay attention to.To prevent magazine pickup in air accumulator
VP01E photoelectric liquid-level switch probe positions, need to be arranged y-type filter in front of it, and filtering dust, particle, air accumulator fall off
Other solid magazine particulate matters, the only liquid waters such as corrosion can pass through.The utility model is conducive to protect equipment, energy conservation drop
Consumption, avoids fault spread.
In conclusion the utility model using liquid-level switch detection air accumulator lead to oxygenerator gas in whether contain water
Point, liquid water is touched in probe positions, photosignal transformation issues digital signal and leads to PLC programmable controller, and PLC can
Programmable controller issues sound-light alarm and operator is reminded to pay attention to.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
