Abstract
The utility model provides a gas mixer. The gas mixer comprises a primary gas inlet tube, a mixed gas inlet tube, a pre-mixing tube, a mixing tube, a necking type guide tube, a mixing cavity, a gas exhaustion tube and blade units, wherein the mixer adopts a left-right symmetrical structure, is equipped with the mixing cavity in the middle, and outwards connected with the necking type guide tube, the mixing tube and the pre-mixing tube at the two sides in sequence; the gas exhaustion tube is connected with the edge of the mixing cavity; a wide port end of the necking type guide tube is connected with the mixing tube; a narrow port end of the necking type guide tube is connected with the middle part of the end surface of the mixing cavity; blade units which are arranged by staggering by 90 degrees and twisted by 180 degrees are arranged in the mixing tube; the primary gas inlet tube and the mixed gas inlet tube are connected with the pre-mixing tube by a Y-shaped pipeline. The gas mixer disclosed by the utility model is reasonable in design and low in cost. The gas mixture is applied to mix two gases, so that the two gases can be quickly mixed uniformly and sufficiently, and the mixed gases satisfy requirements of the standard gas for metering.
Description
Technical field
The utility model relates to gas mixer technical field, is specifically related to one and can detects gas alarm gas mixer for metering.
Background technology
Major part metering scientific research institute is detected in the process of gas alarm in metering, preparation standard gas voluntarily.Existing detection method is that the calibrating gas of purchasing variable concentrations passes into gas alarm and detects, and it is many that the method takies gas cylinder quantity, causes the wasting of resources; In testing process, need constantly to change gas cylinder, complex operation.
Chinese patent CN202621045U discloses a kind of gas mixer, sneaking into gas mixes by the circulate main air inlet pipe of mainstream gas of the conical pipe of circle distribution, then by closed-entry mozzle enter volume larger and the hybrid chamber of built-in choke apparatus mix, but its mist can not meet the requirement of metering use calibrating gas completely.
Summary of the invention
The utility model provides and can make gas realize a kind of gas mixer mixing for four times, has overcome the deficiency existing in above-mentioned gas blender, can make two kinds of gas rapid mixing evenly, fully, can meet the requirement of metering calibrating gas.
The technical scheme that the utility model adopts is: a kind of gas mixer, comprise main air inlet pipe 1, sneak into gas air inlet pipe 2, premixed pipe 3, mixing tube 4, closed-entry mozzle 5, hybrid chamber 6, blast pipe 7 and blade unit 8, blender adopts symmetrical structure, middle is hybrid chamber 6, and both sides outwards connect closed-entry mozzle 5, mixing tube 4, premixed pipe 3 successively; Described blast pipe 7 is connected with hybrid chamber 6 edges; The wide mouth end of described closed-entry mozzle 5 is connected with mixing tube 4, and the slot end of closed-entry mozzle 5 is connected with hybrid chamber 6 end face middle parts; The interior setting of described mixing tube 4 blade unit 8 of 180 ° of distortions of 90 ° of arrangements that staggers; Described main air inlet pipe 1, sneak into gas air inlet pipe 2 and connect premixed pipe 3 by Y tube road.
Described main gas with sneak into gas and first tentatively mix at premixed pipe 3.
The described gas by premixed pipe 3 carries out secondary mixing at mixing tube 4.
Described closed-entry mozzle 5 taperings are that 1:0.5～1:5, wide mouth part are more than or equal to 3:1 with the ratio of slot end diameter of a circle.
The mist that described hybrid chamber 6 both sides enter clashes in opposite directions at hybrid chamber 6 middle parts to flow and carries out three mixing.
Gas after described impingement mix expands and carries out four mixing at the larger hybrid chamber 6 of volume.
The beneficial effects of the utility model are: 1, the utility model overall construction design rationally, structure is comparatively simple, cost is lower; 2, application the utility model, mixes gas for four times, good mixing effect, and after mixing, the satisfied metering of gas detects the requirement with calibrating gas; 3, application the utility model, has solved current metering and has detected in gas alarm process the difficulty of preparation standard gas voluntarily, has reduced calibrating gas steel cylinder use amount.
Accompanying drawing explanation
Fig. 1 is gas mixer overall structure schematic diagram;
Fig. 2 is mixing tube intra vane cell schematics.
The main air inlet pipe of symbol description: 1-; 2-sneaks into gas air inlet pipe; 3-premixed pipe; 4-mixing tube; 5-closed-entry mozzle; 6-hybrid chamber; 7-blast pipe; 8-blade unit.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.
Before use, blender is vacuumized with vavuum pump, then the mainstream gas of certain flow enters premixed pipe 3 by the main air inlet pipe 1 in both sides, and the gas of sneaking into of certain flow is sneaked into gas air inlet pipe 2 by both sides and entered premixed pipe 3 simultaneously, tentatively mixes; Through the preliminary mist mixing enter inner arrange stagger 90 ° arrange, the mixing tube 4 of the blade unit 8 of 180 ° of distortions, carry out secondary mixing; And then, both sides mist flows into hybrid chamber 6 by closed-entry mozzle 5, clash in opposite directions at hybrid chamber 6 middle parts mobile, carry out three times mix; Gas after impingement mix carries out four times in the larger interior expansion of hybrid chamber 6 of volume to be mixed, and mixed effect is further promoted; The mist fully mixing is finally discharged by blast pipe 7.
