Van bướm kín mềm là gì?

Van bướm niêm phong mềm, as a component used to cut off the pipeline system and control the flow, has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. The butterfly plate of the van bướm con dấu mềmđược lắp đặt theo hướng đường kính của đường ống. Trong kênh hình trụ của thân van bướm, tấm bướm hình đĩa quay quanh trục và góc quay nằm trong khoảng từ 0° đến 90°. Khi vòng quay đạt 90°, van mở hoàn toàn. Đặc điểm của van bướm thép không gỉ có tuổi thọ cao mới và các vấn đề trong việc sử dụng van bướm. Van bướm kín mềm có thể được chia thành van bướm kín mềm kiểu mặt bích, van bướm kín mềm kiểu wafer và van bướm kín mềm hàn theo phương pháp kết nối.

Van bướm niêm phong mềm, as a component used to cut off the pipeline system and control the flow, has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. In the known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitations of structural features, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. An existing relatively advanced butterfly valve is a triple-eccentric metal hard-sealed butterfly valve. The valve body and the valve seat are connected components, and the sealing surface of the valve seat is surfacing with heat-resistant and corrosion-resistant alloy materials. The multi-layer soft stacked sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, this butterfly valve has high temperature resistance, easy operation, and no friction when opening and closing. The advantages of excellent sealing performance and extended service life
