Description

Technical Field

[0001] The utility model relates to the relevant field of high-temperature furnaces, and in particular to a gas pressure stabilizing device in a high-temperature furnace. Background Art

[0002] The field of high temperature furnaces is an important technical field widely used in many industries such as materials science, chemical engineering, metallurgy, ceramic manufacturing, and laboratory research. It involves the use of equipment that can generate and maintain extremely high temperatures (usually between hundreds of degrees Celsius and thousands of degrees Celsius) for the thermal treatment, chemical reaction, sintering, melting, and testing and research of physical properties of materials. The advancement of high temperature furnace technology has not only promoted the development of related industries, but also provided strong support for the development of new materials and the improvement of product quality and performance. With the continuous advancement of science and technology, the intelligence, efficiency and environmental protection of high temperature furnaces have become an important trend in the development of this field.

[0003] Existing gas pressure stabilization devices in high-temperature furnaces play an important role in maintaining the stability of gas pressure in the furnace, but they still have certain limitations when dealing with certain special situations. Specifically, these devices often lack the function of automatic exhaust and pressure relief, which means that when the pressure in the high-temperature furnace increases abnormally, the excess gas cannot be released quickly and effectively, which may cause the pressure in the furnace to get out of control and even cause safety accidents;

[0004] In addition, the sealing plate in the existing gas pressure stabilizing device in the high-temperature furnace is under tremendous pressure under high temperature and high pressure environment, and is therefore prone to wear. Once the sealing plate is damaged, it will not only affect the pressure stabilizing effect of the gas in the furnace, but may also cause safety hazards such as gas leakage. However, the sealing plate inside the existing high-temperature furnace is usually fixedly connected to the piston plate, which makes it inconvenient to replace the worn sealing plate, which will affect the use of the pressure stabilizing device.

[0005] Therefore, we have made improvements to this and proposed a gas pressure stabilizing device for a high-temperature furnace. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a gas pressure stabilizing device in a high-temperature furnace, which solves the problems mentioned in the background technology.

At this time, the block will move into the groove, and one end of the block will not engage with the groove, which is convenient for replacing the worn sealing plate and improves its practicality.

At the same time, the inclined groove 711 will squeeze the sliding block 708 through its own inclined surface to reset the sliding block 708.
