Description

Technical Field

[0001] This utility model relates to the field of distribution valve technology, specifically a distribution valve sealing structure. Background Technology

[0002] In a conveying system, there is usually a single pressurizing device that needs to deliver different materials to different containers. This requires switching pipelines from time to time during the conveying process so that the materials are transported in different pipelines. This allows a single pressurizing unpacking device to fill different containers with materials. Therefore, many distribution valves need to be added to the conveying system to achieve pipeline switching.

[0003] After prolonged use, the sealing ring of the distribution valve will wear out, which will reduce the airtightness between the valve seat and the valve body. Furthermore, it will be inconvenient to install the distribution valve after the sealing ring is fitted onto the valve body. At the same time, the existing valve seat cannot support the distribution valve, which will cause the pipeline on the valve seat to bear greater pressure and be prone to damage.
