Furthermore, the control of the air flow is convenient and accurate.
Description
Technical field
The utility model relates to a kind of gas control valve, is specifically related to a kind of gas flow regulating valve.
Background technique
At present, the main 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 overpressure, the area of contact of Argon Bubble and molten steel diminishes, effect is undesirable, and desirable situation is that argon gas stream spreads all over ladle everywhere, increases area of contact 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 flow-rate 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 only tens millimeters of the open degree of above-mentioned valve, be difficult to realize the accurate control of large-scale flow, when Argon amount trace is regulated, can not make one's wish fulfilled.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of gas flow regulating valve is provided, and it is simple in structure, and is easy to use, volume is small and exquisite, is convenient to carrying, and automaticity height, gas flow are regulated accurately, cost of production 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 gas flow regulating valve, comprise housing, enclosure interior is arranged with gas-entered passageway and outlet passageway in parallel, by valve seat solenoid valve is installed on the described housing, it is characterized in that: described enclosure interior is provided with valve-rod cavity supporting with solenoid valve and that be communicated with gas-entered passageway, described valve-rod cavity inside is provided with the valve rod that is used for regulating valve stem chamber aperture, described valve-rod cavity bottom is communicated with the suction port of described solenoid valve by inlet hole, described outlet passageway is communicated with the air outlet of described solenoid valve by air outlet hole, and described stem lower portion termination has tapering.
Be provided with the O RunddichtringO between described valve rod 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 gas flow regulating valve is simple in structure, uses very easy.
(2) this gas flow regulating valve 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 the automatic control electromagnetic valve switch of controller, the automaticity height.
(4) this gas flow regulating valve is by the up-down adjustment of valve rod, and the control stem lower portion has the area that opens between the termination of tapering and the valve-rod cavity, thus the control charge flow rate, and gas flow is easy to adjust, accurate.
(5) this gas flow regulating valve all is convenient to produce, buy very much, thereby its cost of production is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
