Oxygen ball valve
The tempering furnace is the nuclear device of the coal tempering unit. The combustion pressure in the tempering furnace is 4.0~6.3MPa, and the temperature is 1100~1300 ℃. It is a dangerous device. Therefore, the safety and reliability of the tempering furnace is the first, and the second is to ensure the stability of the reaction products. It is necessary to accurately control the flow of water slurry and oxygen into the tempering furnace. The reaction in the furnace is the combustion reaction of high temperature and high pressure, and the demand for oxygen. In order to ensure the normal combustion state and the safe operation of the furnace, the flow of oxygen must be accurately controlled. The furnace is equipped with 3 oxygen flow valves to control the oxygen flow into the furnace, namely, the oxygen flow regulating valve, the oxygen cut-off valve and the oxygen venting valve. Compared with the oxygen-reducing valve in the general process, the oxygen-reducing valve in the furnace needs to withstand high pressure difference, good flow rate and strict sealing level. The maximum cut-off pressure difference of the oxygen cut-off valve can reach 5.0~7.0MPa, and the leakage level needs to reach Vl level. Generally, the straight-through type 0 hard seal ball valve is selected for this type of cut-off valve.

Generally, the straight-through type 0 hard seal ball valve is selected for this type of cut-off valve. Structure classification: It can be divided into floating ball structure and fixed ball valve. By adopting special hardening treatment technology for the sealing surface of the ball seat, the technical problem of hard metal bonding in the application of high pressure and temperature ultra-pure body is completely overcome. The switch is smooth and unglued, degreasing and degreasing, preventing water supply and static electricity, and the sealing performance period reaches a leakage level of level 6.
