No well, flammable gas alarm data the most accurately and reliably, to the judgement of industrial accident and strick precaution and people's life wealth
Produce safety and play the most important effect.Clear stipulaties in " metric method ", flammable gas alarm belongs to the pressure of national regulation
The measurement instrument of calibrating, it should carry out periodic calibration in accordance with the law, apply for verification the most according to the rules or examine and determine underproof, must not make
With.Therefore, alarm work whether normal relation is to the safety of whole enterprise, it is necessary to alarm is carried out periodic verification.
The assay device and the method that are currently used for flammable explosive harmful gas detection, alarm device are the simplest, mainly by gas
Bottle, decompressor, effusion meter form, and device is simple and crude, inconvenient operation, have harm greatly to environment and operator, due to
The simple and crude function singleness of device, be only suitable in this way examining and determine have can directly sound and light alarm portable poisonous, flammable easily
The calibrating of quick-fried alarm.And, for being arranged on the fixed poisonous and harmful at scene, flammable explosive alarm, at present this neck
Special calibration equipment that territory is not the most relevant and device, this just brings inconvenience to our assay calibration work.Due to
Technology and the limitation of relevant device, the accuracy of assay calibration also has been difficult to significantly break through and improve, result also in not
Can adapt to current social development and the demand of economic growth.Then, it is necessary to carry out the renewal of technology putting us before this
With the replacement of device, thus set up more stable, more accurate, more reliable Novel alarm assay device.
Summary of the invention
The purpose of this utility model is in order to solve current flammable gas alarm assay device backwardness, inconvenient operation
Problem, spy provides a kind of flammable gas alarm assay device.
This utility model provides a kind of flammable gas alarm assay device, it is characterised in that: described fuel gas report
Alert device assay device include steel cylinder 1, gas circuit 2, pressure transducer 3, effusion meter 4, electromagnetic valve 5, alarm 6, data acquisition unit 7,
PLC8, industrial computer 9；Wherein: steel cylinder 1 passes sequentially through gas circuit 2, pressure transducer 3, effusion meter 4 are connected with electromagnetic valve 5, electromagnetic valve 5

Operation principle and the flow process of this system be: each calibrating concentration point calibrating gas required by vertification regulation is connected to
On device pipe interface, and opening the valve of each calibrating gas steel cylinder, regulation air relief valve is adjusted to the needs that vertification regulation specifies
Calibrating pressure, opens effusion meter simultaneously, adjusts the calibrating flow specified to code；By the type of sensor, sensor is connected to
On binding post on instrument, and sensor is examined and determine interface live the entrance of sensor with special calibrating calotte；At industrial computer
Project information is examined and determine in upper input accordingly, and examines and determine item argument accordingly according to the requirement setting of vertification regulation；Operation system,
System will carry out alarm calibration operation automatically according to the parameter set.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not
It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, the most permissible
This utility model is modified or equivalent, to reach identical technique effect；Needs are used, all in this reality as long as meeting
Within novel protection domain.
