Adopt such scheme, to convert static continuous confession, distribution process to for, distribution process dynamically, improved the uniformity and the stability of distribution precision (reaching 1% after tested) and air feed, reduced production cost, improved product quality, filled up domestic blank in this field.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiments:
Please see Figure 1, the utility model is mainly by gas cylinder 1, gas cylinder 2, two position three-way valve 3, pressure regulator valve 4, pressure sensor 5, flow valve 6, flow sensor 7 and 3-position-3-way valve 8, storage distribution jar 9 and 10, air bleeding valve 11, air compressor machine 12, drying box 13, smelting furnace 14, agitating device 15, axial flow blower 16 compositions such as grade, it is characterized in that: A. gas cylinder 1 is connected with the air inlet of two position three-way valve 3 with 2 escape pipe, the escape pipe of air compressor machine 12 is connected with drying box 13 air inlets, comply with on the outlet pipe of two position three-way valve 3 and drying box 13 and be serially connected with pressure regulator valve 4, pressure sensor 5, flow valve 6, flow sensor 7 and 3-position-3-way valve 8, two groups of outlet pipes of 3-position-3-way valve 8 connect two storage distribution jars 9 and 10 respectively; B. be provided with pressure sensor 5 and air bleeding valve 11 on two storage distribution jars 9 and 10, its inside is provided with axial flow blower 16, two storage distribution jars 9 link to each other with the air inlet of 3-position-3-way valve 8 with 10 escape pipe, be serially connected with pressure regulator valve 4 on the outlet pipe of 3-position-3-way valve 8 successively, pressure sensor 5, flow valve 6 and flow sensor 7, the escape pipe of flow sensor 7 is connected with smelting furnace 14 or agitating device 15.
Operation principle of the present utility model is: gas cylinder 1 and 2 is equipped with SF
6And CO
2, the SF in the gas cylinder 1 and 2 at first
6Pass through two position three-way valve 3 with minimum pressure, regulate pressure through pressure regulator valve 4, whether the pressure of monitoring gases through pressure sensor 5 is qualified, controls the flow of gases again through flow valve 6, through the flow of flow sensor 7 monitoring gases, be transported to storage distribution jar 9 or 10 by 3-position-3-way valve 8; CO in the gas cylinder 1 and 2 then
