進口襯氟閘閥
德國巴赫進口襯氟閘閥概述：
進口襯氟閘閥是一種zui帶見的啟閉閥門，利用兩側(cè)面密封呈楔狀的閘板來接通或截斷管路中介質(zhì)，楔式閘閥不允許微量開啟在管路中作節(jié)流裝置用，以免因高速流動的介質(zhì)沖蝕而加快密封面的損壞。FEP(F46)、PCTFE(F3)襯氟閥門適用在-50℃~150℃的各種濃度的王水、氫氟酸和各種有機酸、強酸、強氧化劑，F(xiàn)EP還適用于各種濃度的強堿有機溶劑以及其它腐蝕性氣體、液體介質(zhì)的管路上使用。
Imported fluorine gate valve
Introduction of the German Bach fluorine gate valve:
The import of fluorine valve is one of the most common with open and close the valve by two side sealing a wedge shaped medium to connect or disconnect the line, wedge gate valve does not allow for trace open throttle device in the pipeline, so as not to damage the sealing surface and accelerate the erosion caused by the medium high speed flow. FEP (F46), PCTFE (F3) fluorine valve for the aqua regia, hydrofluoric acid and various organic acids, strong acid, strong oxidizing agents in various concentrations of -50 DEG ~150 DEG C, the use of strong organic solvent FEP is also applicable to various concentration and other pipeline corrosive gas and liquid medium.
進口襯氟閘閥的定義：
1.閥體有扁體和圓體兩種，閥體、閥蓋、閘板的閥桿等直接與介質(zhì)接觸部件，全部包襯FEP（F46）或PCTFE（F3）等氟塑料。
2.密封副為FPE（F46）/FEP（F46）摩擦系數(shù)小，啟閉力矩低。
3.填料采用PTFE（F4）標準填料，密封性能好，維修更換方便。
4.采用彈性閘板，可補償閘板密封面與閥座密封面之間楔角偏差，吻合度好，密封效果理想。
5.介質(zhì)可從兩側(cè)任意方向通過閘閥，適用于介質(zhì)方向可能改變的管路上作啟閉裝置。
Imports of fluorine gate valve definition:
The 1 valve body and a flat cylinder two, valve body, valve cover, valve gate directly contacts with the media, all of the lining of FEP (F46) or PCTFE (F3) and fluorine plastic.
2 seal for FPE (F46) /FEP (F46) friction coefficient is small, the opening and closing torque is low.
3 packing with PTFE (F4) standard packing, good sealing performance, easy maintenance and replacement.
4 the use of elastic gate, can compensate the gate sealing surface and the valve seat sealing surface between the wedge angle deviation, good agreement, sealing effect is ideal.
5 medium can be used from both sides of any direction through the gate valve, suitable for the direction of the media may be changed on the pipeline for the opening and closing device.
