詳細介紹

結構說明Structre instruction:

1.閥座為鑲嵌PTFE或填充PTFE密封圈的剛性浮動閥座,具有雙重密封效果,閥座由端部O型圈施加予緊力,并由浮動閥座的活塞效應達到進出口同時密封,這種雙重密封結構使閥體中腔與通道隔離,可以在工作狀態下檢修閥門,排除體腔內殘留物。

2.閘板為一長方形平行平板,其上開一與通道直徑相同的通孔(帶導流孔).也可不開孔(不帶導流孔).全啟時,通道平滑為直管段,流阻系數低,壓力損失小,開啟與關閉時閘板與閥座始終相互接觸,即可擦試附著在密封面間的顆粒污物,又可使密封面不被介質直接沖刷而得到保護。

3.閥桿與閘板采用“Tt,形槽連接;

4.扁體閥門中法蘭采用金屬柔性石墨墊片,圓體閥門中法蘭采用O型密封圈密封:

5.密封面處設有油封裝置,緊急狀態下可旋緊注脂器注入密封脂以保證密封的可靠;

6.閥門為全封閉式,并在閥蓋上端部設有開度指示器,可隨時指示閥門的啟閉式狀態與高度;

7.閥桿、閥座和閘板等零件表面都經過特殊的熱處理( MoS2):

8.閥體底部和閥蓋上部均設有泄壓裝置,即可排放臟物,又可排放由于溫升等原因造成的升壓:

9.手輪順時針轉動為關閉,反之為開啟。

1.Valve base is trie rigid floating one inlayed or filled with PTFE sealing ring, and tias double sealing effect. Synchronous sealing at trie inlet and outlet activates  thanks  to the tension from O ring at the top  of valve base  as  well as the piston effect of floating  valve  base. This dual-sealing structure is able to completely separate the middle cavity of valve body from the bare, and it is possible to examine and repair the valve  under working condition and remove the leftover in body cavity.

2.Flashboard is an oblong parallelflat plate, on which a through hole  (with bleed hole)  is available with the same diameter of bore. The through hole (without bleed hole) is unnecessary if not required on it. In the state of fully open,  smooth bore  is  a straight pipe with low flow resistance  and small pressure loss. Flashboard always keeps connecting wlth valve base wheneverlt Is open or closed, so that  the granule dirt stuck on sealing surface can be clean up andthe sealing surface be kept from directly eroding by medium.

3. T type groove connection between valve stem and flashboard.

4. The flange In the flat valve adopts metal soft graphite spacer and the flange in the round valve adopts O sealing rlng for sealing.

5. There is oil seal device on sealing surface. In emergency condition, you may screw filling greaser and inject sealing  grease so as to assure absolutelyreliable sealing.

6. Valve is of fully enclosed type. On the upper end of the valve cover, there Is a jaw opening indicator, which can Indicate the state of open and close andheight of valw at any time.

7. The surfaces of valve stem, valve base, flashboard and other parts have been processed through special heat treatment.

8. Pressure release devlces set on the bottom of valve body and the top of the valve cover separately can not only discharge dirt, but also release the rls-ingpressure due to temperature rise and other causes.

9.  Close the valve by turning the handwheel clockwise and open on the contrary.
