产品结构特点Products design features
●阀体采用铸造结构。
The body uses a cast structure
●阀座采用O形密封圈密封和施加预紧力的浮动阀座结构,使阀门进出El双向密封;并且该结构的启闭力矩仅为普通阀门的l/2,能达到轻松开、关阀门。
The seat ring uses the floating seat ring structure with O-seal ting sealed and Pre-rightenmg fo rce apPIied to have mlet and outlet dual-way sealed;and the open-close moment wifh fhis structure is l/2 that of the common valves only,able to lightly open and close valves.
●阀座采用密封面上镶嵌PTFE,具有PTFE对金属和金属对金属的双重密封,PTFE密封面同时清除闸板脏物的作用。
The seat ring uses the sealing face inlaid with PTFE.so has dual seals of PTFE to metal and metal to metal,the PTFE sealing face also acts as removing the dirt on the wedge disc
●阀门的闸板,无论是全开或是全关始终与密封面吻合,密封面得到保护不受介质直接;中刷,从而延长使用寿命。
The wedge disc of the valve is always fitted with the sealing face whether in fullopen or fullclose status to have the sealing face Protected without being directly eroded by the medium so as to extend the duration. 
●阀门在全开时,通道平滑为直线,流阻系数极小,无压力损失,可通毛球清扫管线。
When fully opened,the valve s channel is smooth and linear,with an extremely small flow resisting coefficient and no Pressure loss,and the Pipeline can be cleaned with hair-ball through it. 
●阀门关闭时能自动卸掉内腔高压(详见工作原理图),保证使用安全。
Automatic removal of the hlgh Pressure in the internal cavity when the valve is about to close(see the working Principle dlagram for the details)so as to ensure safety.
●采用封闭齿轮转动启闭指示机构,能长期清晰地反映阀门的启闭情况。
Use a sealed gear-driving open-close indicating mechanism,which is able to clearly show the open-close condition of the valvein along term.
●直埋式阀门外表面采用环氧煤沥青防腐处理,能与管线同寿命。
The external surface of the directly built-in valve is corrosion resisting treated with epoxy coal bitumen and can be the same duration as the Pipeline.

  1、阀门内部压力相当时(1),闸板处于闭合状态,阀座表面PTFE密封环形成初始密封,每次阀门开或关时,阀座圈能清洁闸板两侧。(如图l)
  With equal Pressu re throughout the valve(and the gate in closed position),and initiaseal(1)is formed with the raised PTFE ring on the faces of the seats(The seat-inserts clean both sides of the gate each time the valve is opened or closed)

  2、对阀门施加管道压力时(2),压力作用于闸板,迫使它贴近出I:1阀座上的PTFE环,压缩它直到闸板停在钢制阀座上,这样,就形成了双重密封,首先是PTFE对金属密封,然后是金属对金属密封,阀座也被牢固地推到凹槽,在这一点(3),0形圈阻止任何后部介质流。(如图2)
  As line pressure(2)is applied to the valve it acts on the gate,forcing it against the PTFE ring on the downst ream seat,comp ressing it untiI the seat against the steel seat Thus,a double seal is formed first,a PTFE-t0-metal seal:then,metal-t0-metal The seat is also forced firmly into its recess The O-ring(3)p revents any downst ream flow at this point

  3、阀腔压力泄放后,形成进口密封,管道压力作用于进口阀座(4),使其移向闸板,这时形成PTFE对金属的密封,同时,0形圈(5)与阀座凹槽形成紧密的密封。(如图3)
  Upstream seal is Provided when valve cavity Pressure is bled off This is caused by the force of line pressure acting against the upst ream seat(4)moving the seat against the gate and providing a tight PTFE-to metal seal at this point At the same time the O-ring(5)forms a tight seal with the seaf recess.

  4、阀门自动泄放多余的压力,当阀腔压力大于管道压力时,由于热膨胀,进口阀座推向凹槽阀腔内多余的压力在阀座与闸板之间泄放到管道中。(如图4)
  Valve automatically reIieves itself of excessive valve cavity Pressure When valve cavity Pressure exceeds line Pressure from such causes as thermal expansion the upstream seat is forced back into its recess and the excess Pressure in the valve cavity is bled between the seat and the gate into the line.
