Abstract
Portable automatic gas sampling ware. The ration gas injection gas detecting tube that awaits measuring is gathered in the effect of gas sampling ware. The gaseous volume that manual gas sampling ware pours into into and the speed of injection depend on operating personnel's experience, can cause the error to gaseous testing result. Portable automatic gas can automatic control gas production volume and gas injection speed, reduces and detect the error. A portable automatic gas sampling ware which constitutes and includes: air inlet (1), gas outlet (2), air inlet and gas outlet connect through tee bend valve (3), the tee bend valve connect sample thief cavity (11) simultaneously, the internal portion of sampling cavity be fixed with lead screw (4), lead screw articulated sealed slider (5), lead screw articulated step motor (8) simultaneously, step motor electricity connect drive module (7), drive module electricity connect master control circuit (6), master control circuit simultaneously the electricity connect button (9) and LCD liquid crystal display (10).
Description
Technical field
The utility model relates to a kind of Portable Automatic gas sampler.
Background technology
Easy as one, the efficient method for quick of gas detect tube method and being widely used, the composition of the method comprises gas detecting tube and gas sampler.Wherein, gas sampler is generally manual malleation or suction type sampling thief, and its operating process relies on the experience of staff, and gas production is read by the scale on handle, and gas injection speed relies on operating personnel's subjective judgement.This hand sampling thief exists that sampling quantity is inaccurate, the drawback of gas injection speed instability, and these two drawbacks will cause results such as sampling quantity is too much or very few, gas detecting tube variable color cross section out-of-flatness, cause testing result to produce error the most at last, affect the judgement of operating personnel to Environmental security degree to be measured.
Summary of the invention
The purpose of this utility model is to provide a kind of Portable Automatic gas sampler, improve that manual gas sampling thief gas production is inaccurate, the drawback of gas injection speed instability, single-chip microcomputer, sealing slide block and screw mandrel is utilized to control to gather the volume of gas, utilize the speed of step motor control injecting gas, and gas collecting volume and gas injection speed can be selected by button, improve the accuracy that gas detect tube method detects.
Above-mentioned object is realized by following technical scheme:
A kind of Portable Automatic gas sampler, its composition comprises: air intake opening, gas outlet, described air intake opening is connected by three-way valve with described gas outlet, described three-way valve connects sampling thief cavity simultaneously, described sampling inside cavity is fixed with screw mandrel, the hinged sealing slide block of described screw mandrel, described screw mandrel is hinged stepper motor simultaneously, described stepper motor electrical connection driver module, the described governor circuit described in driver module electrical connection, described governor circuit is electrically connected button and LCD liquid crystal display screen simultaneously.
Described button comprises key in power key, selection, selects lower key and OK button, and described governor circuit is made up of single chip circuit and peripheral circuit.
Beneficial effect:
1. the utility model can adopt stainless steel sampling thief cavity, can the multiple gas to be measured of quantitative collection, anticorrosion, rust-preventing characteristic good.
2. the utility model adopts single chip circuit to control gas collecting and the injection of automatic gas sampler, and can carry out collection and the injection of gas to be measured by prescribed volume and speed, degree of accuracy is high, degree of stability good, reliability is strong.
3. the utility model adopts the LCDs of 1602, compact, and can realize display and the selection of gas volume and gas injection speed.
4. the utility model adopts anti-explosion box body structure, can use under mine and under other rugged surroundings.
Accompanying drawing illustrates:
Accompanying drawing 1 is inner structure schematic diagram of the present utility model.
Accompanying drawing 2 is theory diagrams of governor circuit in accompanying drawing 1.
Accompanying drawing 3 is schematic diagrams of single chip circuit in accompanying drawing 2.
