產品詳情 Product details

三通針型閥采用**鍛鋼加工，適用一進兩出切換管控，,也可以將其中一個出口連接儀表,來作為儀表閥使用。閥尖垂直運動，無旋轉使用壽命長，通過旋轉閥桿的位置來改變兩個主孔或主孔和旁邊孔之間的連通The three-way needle valve is made of high-quality forged steel and is suitable for one in two out switching control. One of the outlets can also be connected to the instrument for use as an instrument valve. The valve tip moves vertically without rotation and has a long service life. By rotating the position of the valve stem, the connection between the two main holes or between the main hole and the adjacent hole can be changed

進口三通針型閥設計標準 Design standards

非旋轉閥桿Without rotating the valve stem

錐形閥芯或球形閥芯

閥尖垂直運動，無旋轉，使用壽命長

動載何密封設計，填料螺母可外部調整。

閥體采用整體式(精鑄和鍛壓形閥體結構)。

兩件式填料設計，減少了閥桿填料的磨損，填料可通過上部的碟簧自行補償減少手輪的操作扭矩

上閥桿螺紋經滾壓硬化處理，下閥桿表面經特殊硬化上閥桿螺紋的潤滑脂與系統(tǒng)介質隔離
