It is particularly suitable for two-way sealing and valve body corrosion prone situations, as a flow regulation and interception medium
進口氣動中線蝶閥產品詳情 Product details
(法蘭，對夾)進口氣動中線軟密封蝶閥是以壓縮空氣0.4-0.7MPa的氣源為動力，驅動閥桿帶動帶碟板在閥體內做0-90度的旋轉，達到對蝶閥全開和全關的操作控制 RETZ (Flange, wafer) The inlet pneumatic midline soft seal butterfly valve is powered by 0.4-0.7MPa compressed air, which drives the valve stem to drive the disc plate to rotate 0-90 degrees in the valve body, so as to achieve full opening and full closing operation control of the butterfly valve
結構特點 Structural characteristics
蝶板的回轉中心(即閥桿的中心)位于閥體的中心線和蝶板的密封面截面上。閥座采用合成橡膠。關閉時蝶板的外圓密封面擠壓合成橡膠閥座，使閥座產生彈性變形而形成彈性力作為密封比壓保證蝶閥的密封 retz品牌The rotary center of the butterfly plate (i.e. the center of the valve stem) is located on the centerline of the valve body and the sealing surface section of the butterfly plate. The valve seat is made of synthetic rubber. When closing, the outer sealing surface of the butterfly plate squeezes the synthetic rubber valve seat, which causes the elastic deformation of the valve seat and forms the elastic force as the sealing specific pressure to ensure the sealing of the butterfly valve
1、小巧輕便，容易拆裝及維修，并可在任意位置安裝 Small and light, easy to disassemble and repair, and can be installed at any position
2、結構簡單、緊湊，操作扭矩小，90°回轉開啟迅速 Simple and compact structure, small operating torque, quick 90 ° rotation and opening
3、流量特性趨直線，調節性能好 Flow characteristics tend to be straight, with good regulation performance
4、蝶板與閥桿的連接采用無銷釘結構，克服了有可能的內泄漏點 The connection between the butterfly plate and the valve rod adopts a pin free structure, which overcomes possible internal leakage points
5、蝶板外圓采用球面造型，提高了密封性能及延長了閥門的使用壽命，帶壓啟閉5萬次以上仍保持零泄漏 The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. The valve can be opened and closed under pressure for more than 50000 times without leakage
6、密封件可更換，且密封可靠達到雙向密封 The sealing element can be replaced, and the sealing is reliable to achieve two-way sealing
7、蝶板可根據用戶要求噴涂覆層，如尼龍或聚四氟類 The butterfly plate can be coated according to user requirements, such as nylon or PTFE
