特點 characteristic
該產品是我公司新開發結構陶瓷的蝶閥，在使用中，密封 面無磨損，而且雙向密封。 該產品與一般蝶閥的根本區別在于結構特殊，它以閥桿的 升降加旋轉起到蝶板與閥體密封面相吻合，達到密封目的 。當閥桿上升到一定位置時，蝶板旋轉90，此時閥門全開 、并也可控制閥桿上升、下降的位置，也可以調節介質流 量生產的閥體和蝶板的密封部位，鑲裝結構陶瓷，耐磨性 能好，適用于易磨損的工況管路上。 | this product is that our company develops the butterfly valve with ceramic structure newly,in using,seal the surface and has not worn and torn,and seal two-wayly.product and general butterfly fundamental difference of valve this lie in structure to be special,it is it is it play function of opening and close,butterfly of board to rotate to add with rise or fall of valve stem.when the valve stem is moved downwards,butterfly"s board rotates to make butterfly"s board and valve body seal the surface identically fist,achieve the sealed purpose.rise to at booking positioning as valve stem,butterfly oard rotate 90,valve at this moment turn on,and can control valve stem rise,position that dr-op all,can regulate the sealed position of valve body and butterfly"s board that the flow of medium produce too,inlay and put the structure pottery,wear-resisting and of good performance,suitable for the operating mode pipeline aptto wear and tear. |
