Description
Technical field
The present invention relates to a kind of pipeline gas detecting instrument manufacturing technology fields, and in particular to a kind of pipeline micrometeor gas
Convey the acquisition device of signal.
Background technique
Pipeline gas conveys detecting instrument equipment at present, is only limitted to the conveying detection of mesohigh gas.Existing low pressure, miniflow
The instrument and equipment for measuring gas conveying detection is expensive, and unfavorable low side is civilian universal.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of cheap pipeline gas for being able to detect that minimum gas flowing
Body flow signals acquisition device.
In order to solve the above technical problems, pipeline low pressure micrometeor gas flow signals acquisition device of the invention, including shell
Body, setting connection intake pipe connection and outlet interface tube on shell, the intake pipe connection install gas tip, in the shell
Photoelectric sensor is set, and setting turning power provides device in the shell, and the turning power provides and is fixedly connected with air-flow on device
Baffle, before gas tip, the turning power provides and is fixedly connected with photosignal reflector on device the blast fence gear, when
Blast fence blown off gas tip when, photosignal reflector excites photoelectric sensor.
When there is gas flowing in pipeline, blast fence is blown off the oral area of gas tip under the action of air-flow, at this time
Since blast fence is fixedly connected with photosignal reflector, the position of photosignal reflector deflects, and blocks photoelectric transfer
The light that sensor issues, so that photoelectric sensor excites, to issue the signal of gas leakage.When the gas in pipeline does not flow,
Under the action of turning power provides device, blast fence is turned back to gear before gas tip, and photosignal reflector is also same at this time
Shi Huiwei, so that photoelectric sensor stops excitation.
Preferably, the turning power provides the memory balance spring and pendulum that device includes Support bracket and is mounted on Support bracket
It takes turns, blast fence and photosignal reflector is installed on the balance wheel.
The turning power that memory balance spring and balance wheel provide it is small sensitive and continue it is reliable, can also will even if very small air-flow
Blast fence is blown open, and air-flow can guarantee reliable return after stopping again.
As an improvement the blast fence and photosignal reflector are separately mounted to the two sides of balance wheel, air-flow gear
Central symmetry of the center of gravity of plate and photosignal reflector about balance wheel.Such structure can prevent balance wheel, blast fence and
The total center of gravity of three parts of photosignal reflector not in the shaft of balance wheel, device not in the horizontal plane when, due to gravity
It rotates, accidentally excites sensor, issue error signal.
As an improvement being fixedly connected with the centrosymmetric frame about balance wheel, the frame on the foreign steamer of the balance wheel
Blast fence is installed in the side of frame, and photosignal reflector is installed in the other side of the frame.
Limiting device is set on the Support bracket.Limiting device can limit the amplitude of fluctuation of photosignal reflector,
It can ensure that balance wheel, position in photosignal reflector accurate rotational to the reflective range of reflective photoelectric sensor signal acquisition, when
No matter pneumatic flow size can ensure that gas conveys the precise acquisition of signal after unlatching air-supplying valve.
The intake pipe connection and outlet interface tube install dustproof filter screen.
With such a structure, pipeline micrometeor gas flow signals acquisition device of the invention, it is defeated in acquisition pipeline
When sending low pressure, micrometeor signal, sensitivity is high, and measurement range is wide in range, and securely and reliably, stability is good, decoration structure features simple design, at
This is low, can meet the needs of market is to low pressure, micrometeor gas conveying signal acquisition.It is pressed onto minute-pressure in suitable conduit conveying,
Acquisition testing of the big flow to the various gas conveying signals of micrometeor.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of pipeline low pressure micrometeor gas flow signals acquisition device of the invention.
Fig. 2 is the top view of pipeline low pressure micrometeor gas flow signals acquisition device of the invention.
Fig. 3 is the scheme of installation of frame, blast fence and photosignal reflector.
Specific embodiment
As shown in Figure 1 to Figure 3, pipeline low pressure micrometeor gas flow signals acquisition device of the invention, including shell 1,
It sets up an organization in shell 1 and detects storehouse 6, setting connection intake pipe connection 2 and outlet interface tube 3, intake pipe connection 2 are pacified on shell 1
Gas tip 4 is filled, mechanism, which detects, is arranged photoelectric sensor 5 on storehouse 6, mechanism, which detects, is arranged Support bracket 7, Support bracket 7 in storehouse 6
It is upper that balance spring 8 and balance wheel 9 are remembered by the installation of diamond bearing 15, the central symmetry about balance wheel 9 is fixedly connected on the foreign steamer of balance wheel 9
Frame 12, blast fence 10 and photosignal reflector 11 are installed on frame 12, blast fence 10 is kept off before gas tip 4,
When blast fence 10 is blown off gas tip 4, photosignal reflector 11 excites photoelectric sensor 5.
When there is gas flowing in pipeline, blast fence 10 is blown off 4 oral area of gas tip under the action of air-flow, at this time
Since blast fence 10 is fixedly connected with photosignal reflector 11, the position of photosignal reflector 11 deflects, and blocks
The light that photoelectric sensor 5 issues, so that photoelectric sensor 5 excites, to issue the signal of gas leakage.When the gas in pipeline does not flow
When dynamic, under the action of remembering balance spring 8,10 throw-over catch of blast fence is before gas tip 4, and photosignal reflector 11 at this time
Also simultaneously return so that photoelectric sensor 5 stop excitation.The turning power that memory balance spring 8 and balance wheel 9 provide is small sensitive and continues
Reliably, blast fence 10 can also be blown open even if very small air-flow, air-flow can guarantee reliable return after stopping again.
Blast fence 10 and photosignal reflector 11 are separately mounted to the two sides of balance wheel 9, blast fence 10 and optical telecommunications
Central symmetry of the center of gravity of number reflector 11 about balance wheel 9.Balance wheel 9, blast fence 10 and photosignal can be prevented anti-in this way
The total center of gravity of entirety of 11 3 parts of tabula rasa composition not in the shaft of balance wheel 9, device not in the horizontal plane when, due to weight
Power rotates, and accidentally excites sensor 5, issues error signal.
Limiting slot 13 is set on Support bracket 7.Limiting slot 13 can limit the amplitude of fluctuation of photosignal reflector, can be really
Position in guarantor's balance wheel 9,11 accurate rotational of photosignal reflector to the reflective range of 5 signal acquisition of reflective photoelectric sensor, when
No matter pneumatic flow size can ensure that gas conveys the precise acquisition of signal after unlatching air-supplying valve.
Intake pipe connection 2 and outlet interface tube 3 install dustproof filter screen 14, and mechanism detects storehouse 6 and intake pipe connection 2 and outlet
O-ring seal is set between interface tube 3.
The above is only the preferred embodiment to invention, not limits the present invention, any
Those skilled in the art are changed or are modified as to change on an equal basis equivalent possibly also with the technology contents of the disclosure above
Embodiment.Without departing from the concept of the present invention, any letter made to the above embodiment according to the technical essence of the invention
Single modification, equivalent variations and remodeling, fall within the scope of protection of the present invention.
