Specific embodiment
Core of the invention is to provide a kind of detection device for being detected to oil-filled equipment, answering through the invention
With detection efficiency and applicability will be significantly improved.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is the application attachment structure schematic diagram.
According to as shown in the figure, the detection device for being detected to oil-filled equipment includes the nitrogen hair that can export nitrogen
Raw device 1, current divider 2 and at least two sets of gas chromatographs 3, the input port of current divider 2 are connected with nitrogen gas generator 1, and current divider 2 wraps
Include at least two delivery outlets, each delivery outlet respectively with corresponding gas chromatograph 3 is one-to-one connects, nitrogen gas generator 1 can lead to
It crosses current divider 2 and exports nitrogen to each gas chromatograph 3.In the present embodiment, gas chromatograph 3 can detect oil liquid, and
Nitrogen applied in detection process is supplied by nitrogen gas generator 1, and detection device is provided at least two gas chromatographs 3, then
Detection can realize by single nitrogen gas generator 1 and supply that this avoids by a nitrogen gas generator while more parts of oil liquid
It is correspondingly connected with the one-to-one setting an of gas chromatograph, and then improves applicability and operation convenience.
On the basis of above-described embodiment, the quantity that can be specifically set the delivery outlet of the current divider 2 of detection device is specially
Two, and pressure-regulating valve 4 is installed in first delivery outlet, as a result, when the pressure value of first delivery outlet is lower than default
Low voltage value in the state of, pressure-regulating valve 4 turn off.It note that since two delivery outlets can provide the output of nitrogen simultaneously,
That is, in practical application, the output pressure of two delivery outlets be it is identical, in the present embodiment, one of delivery outlet installation is set
Pressure-regulating valve 4, this does not limit which specific delivery outlet as first delivery outlet, and is intended to discuss clearly, will wherein one
A delivery outlet is named as first delivery outlet, as a result, two delivery outlets one of them, that is, be named as first delivery outlet
It is mounted in the structure of pressure-regulating valve 4, in the reduction that the output pressure of two delivery outlets is same, is being reduced to preset low pressure
In the state of value, the nitrogen of enough pressure can not be provided by representing two delivery outlets, then pressure-regulating valve 4 realizes shutdown, this
So that it is mounted with that first delivery outlet of pressure-regulating valve 4 stops gas supply, and another delivery outlet continues to keep gas supply, it is clear that pressure
Under 4 off state of force regulating valve, the nitrogen of another delivery outlet output is that can be changed to twice before pressure-regulating valve 4 turns off, because pre-
If low pressure numerical value be the low pressure critical value normally supplied, while be also low pressure modulating valve shutdown response, therefore, another
Normal detection gas is necessarily able to maintain that in the state that the gas output of delivery outlet is double.Structure in through this embodiment is set
Set, avoid air pressure reduce in the state of because simultaneously gas supply due to cause two delivery outlets can not normally supply state, make
Obtaining one of delivery outlet can continue to keep normally to supply, and further improve property and applicability easy to use as a result,.
On the basis of a upper embodiment, it is further disposed at second delivery outlet installation pressure measuring alarm device 5, so-called second
A delivery outlet, this is another delivery outlet other than first delivery outlet in a upper embodiment, in two delivery outlets, first
Delivery outlet is mounted on the basis of low pressure modulating valve that the second delivery outlet installs pressure measuring alarm device 5, then on the basis of a upper embodiment
On, when nitrogen pressure reduces and reaches preset low voltage value, then by pressure-regulating valve 4 first delivery outlet is turned off, in turn,
When pressure further decreases, so that in the state that the delivery outlet of single unlatching carried out by second delivery outlet carries out nitrogen output,
The pressure value of second delivery outlet is still below in the state of preset low voltage value, then pressure measuring alarm device 5 exports alarm signal, this
The output for representing nitrogen pressure is unable to maintain that single delivery outlet, that is, is unable to maintain that the normal gas supply of second delivery outlet, passes through
Alarm signal is to notify to take corresponding measure, and which further improves operation convenience.
In another embodiment, setting detection device further includes spare nitrogen gas generator 6, current divider 2 further include with it is spare
The spare input port that nitrogen gas generator 6 connects, spare input port are all connected to each delivery outlet.In the present embodiment, in normal use
Nitrogen gas generator 1 carried out in the state that nitrogen supply can not be normally carried out for some reason by the input port of current divider 2, then by opening
Spare nitrogen gas generator 6 is opened, and the gas supply to each delivery outlet is realized by the spare input port of current divider 2, is so arranged, keeps away
The disassembly for needing to carry out the nitrogen gas generator that can not be supplied from the input port of current divider is exempted from, and then the generation of other nitrogen is installed again
Device can realize the operation supplied again, in the case where the nitrogen gas generator connecting with input port breaks down, by standby
With the unlatching of nitrogen gas generator 6, will pass through spare input port and respond rapidly to, fast implemented nitrogen and continued to supply, this for
Being carried out continuously for work of detection plays guarantee effect, further improves operation convenience and applicability.
On the basis of the various embodiments described above, it includes air accumulator that detection device, which can also be arranged, and air accumulator is installed on nitrogen hair
Between raw device and current divider, as a result, in gas chromatograph application nitrogen procedure, as needed, occur using gas in each period
More than needing or in the case where few, by the setting of air accumulator, it can be realized nitrogen gas generator and uniformly supply, in the few shape of gas consumption
Under state, the supplied nitrogen of nitrogen gas generator is stored by air accumulator, in the case where gas consumption is big, is provided by air accumulator enough
Nitrogen, which further improves applicabilities.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
