Description

Technical Field

[0001] The utility model relates to the technical field of ceramic valves, in particular to an integrated ceramic valve. Background Art

[0002] Ceramic materials have very small deformation and much higher mechanical strength than metals. Generally, the crystal ions that make up ceramic materials have a small radius, high ion valence, and a large coordination number. These properties determine that the tensile strength, compressive strength, elastic modulus, hardness, etc. of ceramic materials are very high.

[0003] In the prior art, the valve body and the valve controller are connected by bolting at the connection between the two. The disadvantage of this setting is that the bolt connection may loosen due to vibration or external force during use, resulting in a loose connection between the valve body and the valve controller, or even falling off, which will affect the normal operation of the equipment and may cause safety hazards. In addition, the bolt connection needs to be regularly inspected and maintained to ensure the tightness and sealing performance of the connection. However, bolt connections usually require tightening or replacing seals, which may require downtime for maintenance, affecting the continuous operation of the equipment. Utility Model Content
