進口帶平臺三通法蘭球閥
德國托普進口帶平臺三通法蘭球閥技術參數：
口徑:DN15-200 材質WCB.304.316.316L
壓力：PN16-PN40 控制方式：手動、氣動、電動
密封材料：PTFE、304工作溫度：-20℃至+150℃(特殊定做+450°)
產品特點：
1、三通球閥在結構上采用一體化結構，4面閥座的密封型式，法蘭聯接少，可靠性高，設計實現了輕量化。
2、三通球芯分T形和L形，使用壽命長，流通能力大，阻力小。
3、球閥按作用式分單作用和雙作用兩種型式，單作用式的特點是一旦動力源發(fā)生故障時，球閥將處于控制系統(tǒng)要求的狀態(tài)。
Germany imported platform with three flanged ball valve product features:
1, the three way ball valve in the structure of the integrated structure, the sealing surface of the valve seat of the 4 types, flange connection, high reliability, lightweight design.
2, three ball cores T and L shape, long service life, large flow capacity, small resistance.
3, according to the role of single action and double action two types, single action type is characterized by the failure of the power source, the ball will be in the state of control system requirements.
工作原理：
一、開啟過程
1在關閉位置，球體受閥桿的機械施壓作用，緊壓在閥座上。
2當逆時針轉動手輪時，閥桿則反向運動，其底部角形平面使球體脫開閥座。
3閥桿繼續(xù)提升，并與閥桿螺旋槽內的導銷相互作用，使球體開始無摩擦地旋轉。
4直至到全開位置，閥桿提升到極限位置，球體旋轉到全開位置。
二、關閉過程
1關閉時，順時針旋轉手輪，閥桿開始下降并使球體離開閥座開始旋轉。
2繼續(xù)旋轉手輪，閥桿受到嵌于其上螺旋槽內的導銷的作用，使閥桿和球體同時旋轉90°。
3 快要關閉時，球體已在與閥座無接觸的情況下旋轉了90°。
4手輪轉動后幾圈，閥桿底部的角形平面機械地楔向壓迫球體，使其緊密地壓在閥座上，達到*密封。
First, the opening process
1 in the closed position, the ball by the stem mechanical pressure, pressure on the seat.
2 when the handwheel counterclockwise, the stem is the reverse movement, the bottom of the angular plane to disengage the ball seat.
3 stem continues to rise, and with the stem spiral groove guide pin interaction, so that the ball began to spin without friction.
4 until fully open position, the valve stem to the limit position, the ball to the full open position.
Two, closing process
1 turn the handwheel clockwise when the valve is closed, the stem begins to fall and the ball begins to rotate.
2 continue to rotate the hand wheel, the valve stem is embedded in the spiral groove on the role of the guide pin, the stem and the ball at the same time rotate 90 degrees.
3 is about to close, the ball has been no contact with the valve seat under the condition of rotating 90 DEG.
4 hand wheel rotation after a few laps, the stem at the bottom of the angle of the plane mechanical wedge to the compression of the ball, so that it is tightly pressed on the seat, to achieve full sealing.
如何安裝？
（1）取掉法蘭端兩邊的保護蓋，在閥*打開的狀態(tài)下進行沖洗清潔。
（2）安裝前應按規(guī)定的信號（電或氣）進行整機測試（防止因運輸產生振動影響使用性能），合格后方可上線安裝（接線按電動執(zhí)行機構線路圖）。
（3）準備與管道連接前，須沖洗和清除干凈管道中殘存的雜質（這些物質可能會損壞閥座和球）。
（4）在安裝期間，請不要用閥的執(zhí)行機構部分作為起重的吊裝點，以避免損壞執(zhí)行機構及附件。
（5）本類閥應安裝在管道的水平方向或垂直方向。
