[0002] Patent No. CN212804456U discloses a high-sealing valve body. The utility model has a reasonable structural design and all components of the valve have a simple structure, so the maintenance requirements are minimized.

[0003] However, the above-mentioned existing high-sealing valve body includes a body and a through hole running through the body, the body includes a fixed portion located on one side thereof, a docking portion located on the other side thereof, and a flange located between the fixed portion and the docking portion, the through hole includes an inlet recessed inward from the end surface of the fixed portion to form a connecting hole recessed inward from the inlet, a docking hole recessed inward from the end of the docking portion, and a docking cavity recessed inward from the docking hole and connected to the connecting hole. The valve body is an integrated structure. By providing a through hole structure, the valve body can be used in a natural gas transmission pipeline. The fixed portion and the docking portion can be well connected to the pipelines at both ends. The buffering gasket and the sealing gasket can ensure that the valve body will not leak when docking with the pipeline. The integrated structure changes the existing structure of docking two valve bodies and adding a sealing gasket between the two valve bodies, thereby reducing the risk of valve body leakage. The sealing performance of the valve body is very strong. Due to the lack of liquid transportation through multiple pipelines, the practicality of the device is relatively simple.
