Abstract
The invention discloses a rapid gas switching device for use in calibration of an alarm apparatus. The gas inlet of a switch valve is connected with the gas outlets of a first gas valve and a second gas valve through pipelines respectively; the gas inlets of the first gas valve and the second gas valve are correspondingly connected with a first standard gas cylinder and a second standard gas cylinder through pipelines respectively; the gas outlet of the switch valve is connected with the gas apparatus by using a pipeline through a standard flow meter. The rapid gas switching device has the advantages of rapidness in operation, high safety and high efficiency, the calibration time of a standard gas alarm apparatus is shortened greatly, and the working safety is enhanced.
Description
Technical field
The present invention relates to instrument calibration device, for gas alarm instrument, calibrate, particularly a kind of gas apparatus for fast switching for alarm calibration.
Background technology
Existing gas alarm instrument calibrating installation is by air valve, supporting nut, and flexible pipe, gas flow control desk and supporting air-suction cover form.First calibrating gas bottle connects air valve, and the nut on flexible pipe is tightened to air valve connector, and then is connected to gas flow control desk by flexible pipe and nut, in gas flow control desk gas outlet, carries out gas flow control.According to existing calibrating standard, when carrying out the calibration of gas alarm instrument, need to carry out the test of two kinds of calibrating gas, so just need to switch two kinds of calibrating gas at gas flow control desk and carry out orientation ratio pair, during comparison, must close air valve, with flexible pipe, connect a kind of calibrating gas bottle wherein, after test, with spanner, nut be turned on, then flexible pipe is connected to another kind of calibrating gas bottle, tests.After connecting at every turn, must sprinkle and at connector, sentence examination and have or not gas leakage with suds, if any gas leakage, need again with spanner, turn on, after processing, connection tries suds again.After connecting, confirmation by gas flow control desk, carries out calibrating gas flow control calibration gas alarm again.In calibrating gas blocked operation process, easily gas leakage, adjusts consuming time very longly, and particularly CO gas alarm, also relates to safe operation problem.This has just caused calibrating installation inefficiency, poor safety performance, and method of operating is the series of problems such as science not.
Along with the security requirement that enterprise is used gas is more and more paid attention to, the calibration tasks of gas alarm instrument is more and more heavier, is badly in need of a kind of efficiency high, and the device of high safety meets calibration operation.
Utility model content
Technical matters to be solved by this invention is to provide a kind of without dismounting and a kind of gas apparatus for fast switching for alarm calibration of switching standards gas, the work efficiency of raising calibration and alarm calibration security safely and fast.
Technical scheme of the present invention is: a kind of gas apparatus for fast switching for alarm calibration, comprise transfer valve, the air intake opening of described transfer valve is connected with the second air valve gas outlet with the first air valve respectively by pipeline, the first air valve is connected with the second calibrating gas bottle with the first calibrating gas bottle with pipeline is corresponding respectively with the second air valve air intake opening, and the gas outlet of transfer valve is crossed proving flowmeter with device for cleaning pipeline and is connected with gas alarm instrument.
The invention has the beneficial effects as follows: the use of gas apparatus for fast switching, swift to operate, security is good, and efficiency is high, has greatly reduced the time of calibration gas alarm, the security while having improved work.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present invention.
In figure: 1. device body, 11. first air valves, 12. second air valves, 13. transfer valves, 14. proving flowmeters, 2. the first calibrating gas bottle, 3. the second calibrating gas bottle, 4. gas alarm instrument.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.Referring to Fig. 1, a kind of gas apparatus for fast switching for alarm calibration, comprise transfer valve 13, the air intake opening of described transfer valve 13 is connected with the second air valve 12 gas outlets with the first air valve 11 respectively by pipeline, the first air valve 11 is connected with the second calibrating gas bottle 3 with the first calibrating gas bottle 2 with pipeline is corresponding respectively with the second air valve 12 air intake openings, and the gas outlet of transfer valve 13 is crossed proving flowmeter 14 with device for cleaning pipeline and is connected with gas alarm instrument 4.
embodiment:a gas apparatus for fast switching for alarm calibration, switches fast for gas safety, improves gas alarm instrument calibration operation efficiency and security.As shown in Figure 1, gas apparatus for fast switching of the present invention is first that the first air valve 11, the second air valves 12 and transfer valve 13 are interior fixing at device body 1, then by supporting pipeline, connects, and two of pipeline is provided with coupling nut, is provided with O-ring seal in nut; Gas outlet by the first air valve 11, the second air valve 12 connects respectively two air intake openings of transfer valve 13 by pipeline, then proving flowmeter 14 is fixed on device body 1, proving flowmeter 14 air intake openings are connected to transfer valve 13 gas outlets by pipeline, and the gas outlet of proving flowmeter 14 is connected to gas alarm instrument 4 with pipeline; The first calibrating gas bottle 2 is connected with the second air valve 12 air intake openings with the first air valve 11 with the second calibrating gas bottle 3 use pipelines are corresponding respectively.The pipeline that connects use adopts hard steel pipe or flexible pipe.
When carrying out the calibration of gas alarm instrument, according to gas alarm instrument range, select two bottles of calibrating gas of two kinds of variable concentrations, after connecting with pipeline, open the first air valve 11 and the second air valve 12, by rotating transfer valve 13 by gas port rotation to the first air valve 11 or the second air valve 12, realize calibrating gas easily, fast switch.Thereby make the calibrating gas in the first calibrating gas bottle 2 or the second calibrating gas bottle 3 distinguish Engage of standard flowmeter 14 by pipeline, by adjustment criteria flowmeter 14, control gas flow and carry out the calibration of gas alarm instrument 4.The prior installation check of apparatus for fast switching of the present invention is good, does not need to repeat to install, and has directly omitted middle many unnecessary processes, the particularly calibration of CO gas alarm, has reduced the link of Leakage Gas, has greatly improved security.Reached safety, quick, reliable, the object that efficiency is high.
