●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.
●本阀门采用带自密封能力的填料结构,无需经常调节,开、关极为轻便,且密封性可靠,填料函处设有辅助密封油脂注入结构,密封性能可靠,真正达到零泄漏;解决了通用阀门填料处容易外漏的弊病。
This valve uses the Packing structure with the ability of self-seal,needs no constant adjustment,features very light open and close and a teliable seal An assisting sealing grease injection structure is set in the packing to have the sealing performance absolutely reliable and get a true null leak settling the Problem for the packing Place of universal valves to be easiest leak outward
●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.
●全封闭结构,防护’I*生RP-好,可适应全天候要求。
Fully sealed structure leaves a good Protective Property suitable for the requirement of 24-hour duty.
●阀门设有指示杆或观察窗以表示阀门的启闭情况。
An indication rod or vlewmg wmdow is set with the valve to show the open-close conditlon

平板闸阀  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

平板闸阀  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.

量特性分析
带导流孔的平板闸阀,其流量特性等同于同规格的管道,呈等百分比特性,不带导流孔的平板闸阀,其中腔跨度较楔式闸阀小,且属于规则的圆柱体,所以,基本上除压力损失较带导流孔的大外其余特性基本接近。不带导流孔调节型的平板闸阀其对流量的调节特性优于普通不带导流孔的平板闸阀。
FlOW CharalteristiC
The flow characteristic of flat gate valves with a diverslon hole is equal to that of pipelines of the same specification The characteristic is shown in per centum form As for valves without a diversion hole its cavity fly span is smaller than that of wedge gate vales and it is a regular cylindrical object,the refore,characte ristics of the valves are similar except that they have a larger Pressure loss Besides, their flux adjustment behavior is better than that of the ones with a deversion hole.
