Technical field
The utility model relates to a kind of gas meter, is specifically related to a kind of parallel gas meter.
Background technology
At present, the fundamental purpose of steel-making is to reduce content of harmful such as oxygen in the molten steel, sulphur and remove impurity slag inclusion in the molten steel, make the combination property of steel reach its intended purposes, and the mechanism of BOTTOM ARGON BLOWING and effect can be satisfied fully this requirement of making steel, so very fast at home and abroad steel-making of BOTTOM ARGON BLOWING technology gets the nod in the industry and applied.Argon pressure is high, and to stir power big, and bobble rise velocity is fast, but the scope of argon gas stream effect is little during hypertonia, the contact area of Argon Bubble and molten steel diminishes, effect is undesirable, and desirable situation is that argon gas stream spreads all over ladle everywhere, increases contact area and prolongs flow process and the time that argon gas stream rises.The factors such as steel grade of static pressure, slag condition, capacity and the smelting of best Argon pressure and molten steel all have relation, only need very low Argon pressure that the molten steel in the molten steel is foamed in the actual production.
After bottom argon blowing technology obtains the approval of iron and steel enterprise and obtains applying, the Argon technology is arisen at the historic moment, because traditional Argon technology adopts Flux Valve Control, according to flowmeter argon flow amount that reflects and the throughput ratio of presetting, when needing to change flow, the opening amount of controlling electric control valve or diaphragm valve changes for the argon flow, because conventional flow metering journey can't be regulated, thereby when the big and argon flow amount of flowmeter range hour, flowmeter just can't accurately be measured argon flow amount, the sensitivity of flowmeter reaction is very undesirable, often can not make one's wish fulfilled when Argon amount trace is regulated.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of parallel gas meter is provided, and it is simple in structure, and is easy to use, volume is small and exquisite, is convenient to carrying, the automaticity height, and gas flow measurement is accurate, production cost is low, and long service life is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of parallel gas meter, comprise housing, enclosure interior is provided with inlet channel and a plurality of outlet passageway, it is characterized in that: by valve seat a plurality of solenoid valves by the inlet channel parallel connection are installed on the described housing, described enclosure interior is provided with venthole supporting with solenoid valve and that be communicated with outlet passageway, described inlet channel is communicated with the air intake opening of described solenoid valve by air admission hole, the gas outlet of described solenoid valve is communicated with outlet passageway by venthole, described outlet passageway end is equipped with the gas meter that is used to detect tolerance, and described solenoid valve is connected with controller by data line.
Be provided with the O RunddichtringO between described gas meter middle part and the housing.
Described solenoid valve is installed on the housing by bolt, is provided with the O RunddichtringO between described valve seat and the housing.
The utility model compared with prior art has the following advantages:
(1) this parallel gas meter is simple in structure, uses very easy.
(2) this parallel gas meter volume is little, in light weight, is convenient to very much transportation.
(3) according to the automatic control program of system's operation characteristic design, can make controller control each electromagnetic valve switch automatically, the automaticity height.
(4) which flowmeter this parallel gas meter is controlled by the switch of each solenoid valve and is come into operation, and selects the flowmeter of suitable range can accurately measure argon flow amount, realizes that argon flow amount accurately controls.
(5) this parallel gas meter all is convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
