Description
Technical field
Gas alarm technical field is the utility model is related to, especially relates to a kind of multifunctional gas alarm calibrating
Device.
Background technology
At present in calibrating room, it is engaged in the verification process of toxic and harmful gas alarm, used storage calibrating gas
Gas cylinder because outdoor without special connection gas circuit design, it is impossible to pressure and flow control are completed indoors, so calibrating gas bottle
Can only be in the indoor use of calibrating.The fume hood used during gas alarm is examined and determine, its daylight opening DLO ground level reaches 1.05 meters.
In usual calibration operation, women verification worker, it is often necessary to these every 20 kilograms of the calibrating gas bottle of weighing is brought up to and is moved down, not only
Labor intensity is big, and easily occurs because calibrating gas bottle falls, cause personnel injure by a crashing object or gas cylinder damage, leakage accident.With standard
The matching used suspended body flowmeter of gas cylinder, connecting pipe are also required to often dismantle, so since, it is not only time-consuming and laborious but also dangerous,
A large amount of calibrating gas are lost again at the same time.For this we have invented a kind of new multifunctional gas alarm calibrating installation, solve
Above technical problem.
Utility model content
The purpose of this utility model is to provide a kind of safe efficient, conveniently multifunctional gas alarm calibrating dress
Put.
The purpose of this utility model can be achieved by the following technical measures：Multifunctional gas alarm calibrating installation, should
Multifunctional gas alarm calibrating installation includes gas transfer pipeline and calibrating interface, which connects multiple standards
Gas cylinder, to accredited gas alarm transfer criteria gas, which configures multiple calibrating interfaces, with more quilts
The probe connection of calibrating gas alarm is carried out at the same time calibrating.
The purpose of this utility model can be also achieved by the following technical measures：
The multifunctional gas alarm calibrating installation further includes vibration-proof pressure gauge, which is installed on the air shooter
Lu Shang, indicates the gas transfer pipeline Plays gas pressure.
The multifunctional gas alarm calibrating installation further includes a valve and suspended body flowmeter, a valve and the float stream
Gauge is respectively positioned on the gas transfer pipeline, and before which is installed on the suspended body flowmeter, for Temporarily Closed gas circuit, this is floating
Subflow gauge coordinates the aperture of a valve, controls the flow of calibrating gas.
Bypass valve should be further included based on multifunctional gas alarm calibrating installation, which is located at the gas transfer pipeline
On, and after the suspended body flowmeter, calibrating gas is divided into two-way, to detect two accredited gas alarms at the same time.
The calibrating interface includes H2S calibratings interface, CO calibratings interface, iso-butane calibrating interface and methane calibrating interface.
The gas transfer pipeline is connected to multiple calibrating gas bottles by nipple, and multiple calibrating gas bottles are positioned over divider wall
In outer shed special.
Multifunctional gas alarm calibrating installation in the utility model, is placed on outdoor special gas cylinder by calibrating gas bottle and deposits
Store up in canopy, during calibrating, by gas cylinder output gas through Special connecting pipe road, be sent into calibrating room.On indoor gas transfer pipeline respectively
Install one piece of stainless steel vibration-proof pressure gauge additional, for calibrating gas pressure measurement, calibrating gas is last defeated by the control of a valve
It is sent to suspended body flowmeter and carries out flow adjustment.Again by suspended body flowmeter, by-passing valve, the calibrating gas after flow is adjusted is defeated
At most platform is sent to be detected gas alarm.Multifunctional gas alarm calibrating installation in the utility model, examines gas alarm
Determine process, become safe efficient, it is convenient and efficient, achieve ideal using effect.
Brief description of the drawings
Fig. 1 is the structure chart of a specific embodiment of the multifunctional gas alarm calibrating installation of the utility model.

Butane calibrating interface 9, methane calibrating interface 10 form.
Multiple calibrating gas bottles are included into H2S calibrating gas bottles 11, CO calibrating gas bottles 12, iso-butane calibrating gas bottle 13, methane mark
Quasi- gas cylinder 14 is placed in 1 outer canopy of divider wall, during calibrating, by gas cylinder output gas through Special connecting pipe road 2, is sent into calibrating room.
One piece of stainless steel vibration-proof pressure gauge 3 is installed on indoor gas transfer pipeline additional respectively, for calibrating gas pressure measurement, calibrating gas
By the control of a valve 4, finally it is transported to suspended body flowmeter 5 and carries out flow adjustment.Pass through suspended body flowmeter 5, by-passing valve again
6, the calibrating gas after flow is adjusted is divided into two-way, is delivered to tested gas alarm respectively.
During calibrating, the actual pressure for acting on 1. measurement standard gas of stainless steel vibration-proof pressure gauge 3；Remained 2. monitoring in gas cylinder
The amount of residual air body；3. prompting verification worker closes gas cylinder main valve after the completion of calibration operation.
