Vacuum atmosphere furnace is mainly used in sintering, and controllable atmosphere furnace can effectively improve the densification degree of products in the sintering process so as to obtain good properties of products. Apply to electronic ceramics with high temperature structure ceramic sintering, the precision of annealing and microcrystalline glass, crystal precision annealing, preparation of ceramic glaze, powder metallurgy, the sintering of nanomaterials, metal parts quenching and everything should be fast heating-up process requirement of heat treatment, is a scientific research units, universities and colleges, industrial and mining enterprises ideal experiments and production equipment.
Vacuum furnace is well known as a high temperature experimental equipment that can provide atmosphere protection and various atmosphere environments. It can also be used in production. But users prefer to have a stable atmosphere. How to automatically stabilize the pressure in the furnace and replenish the gas in time has become a function of concern for many users.
A simple expansion of solenoid valve on the atmosphere furnace can realize automatic air intake and automatic pressure relief.
One solenoid valve controls intake and the other controls relief. When the pressure gauge detects that the pressure is lower than a certain set pressure, it will give an electric signal to the solenoid valve. When the solenoid valve is connected, the air source will replenish the gas in the atmosphere furnace. When the pressure in the atmosphere furnace returns to the set value, the solenoid valve will close and will not continue to pass the gas. The same principle can achieve automatic pressure relief. This cycle works to ensure that the gas in the furnace is stable and sufficient.
In fact, the principle is simple, but to do a good job of each electrical appliances and the sealing of the trachea joint and so on are details to be carefully considered.
If matched with the gas mixing system to cooperate with the effect will be better, to a large extent to achieve automation, free the time and space of experimental personnel, and control more accurate and accurate.
