產品性能規范Products performance specification

●閥體有鑄造和焊接兩種結構。
Cast and weld two structures with the body
●閥座采用O形密封圈密封和施加預緊力的浮動閥座結構，使閥門進出El雙向密封；并且該結構的啟閉力矩僅為普通閥門的l/2，能達到輕松開、關閥門。
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.
●閥座采用密封面上鑲嵌PTFE，具有PTFE對金屬和金屬對金屬的雙重密封，PTFE密封面同時清除閘板臟物的作用。
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
●金屬對金屬密封的閥門，閥體外部設有注油脂結構，油脂通過注脂器、閥座進入閥門密封面，使閥門達到零泄漏。
For the valve with the metal to metal seal，there is grease injector outside of it，grease gets into the sealing face through the Injector and the seat ring fo have the valve up to null leak.
●帶導流孔閥門的閘板，無論是全開或是全關始終與密封面吻合，密封面得到保護不受介質直接；中刷，從而延長使用壽命。
The wedge disc of the valve with flow guide hole 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
●閥門在全開時，通道平滑為直線，流阻系數極小，無壓力損失，可通毛球清掃管線。
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.
●本閥門采用帶自密封能力的填料結構，無需經常調節，開、關極為輕便，且密封性可靠，填料函處設有輔助密封油脂注入結構，密封性能可靠，真正達到零泄漏；解決了通用閥門填料處容易外漏的弊病。
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
●閥門關閉時能自動卸掉內腔高壓(詳見工作原理圖)，保證使用安全。
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.
●全封閉結構，防護’I*生RP-好，可適應全天候要求。
Fully sealed structure leaves a good Protective Property suitable for the requirement of 24-hour duty.
●閥門設有指示桿或觀察窗以表示閥門的啟閉情況。
An indication rod or vlewmg wmdow is set with the valve to show the open-close conditlon

	1、閥門內部壓力相當時(1)，閘板處于閉合狀態，閥座表面PTFE密封環形成初始密封，每次閥門開或關時，閥座圈能清潔閘板兩側。(如圖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、對閥門施加管道壓力時(2)，壓力作用于閘板，迫使它貼近出I：1閥座上的PTFE環，壓縮它直到閘板停在鋼制閥座上，這樣，就形成了雙重密封，首先是PTFE對金屬密封，然后是金屬對金屬密封，閥座也被牢固地推到凹槽，在這一點(3)，0形圈阻止任何后部介質流。(如圖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、閥腔壓力泄放后，形成進口密封，管道壓力作用于進口閥座(4)，使其移向閘板，這時形成PTFE對金屬的密封，同時，0形圈(5)與閥座凹槽形成緊密的密封。(如圖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、閥門自動泄放多余的壓力，當閥腔壓力大于管道壓力時，由于熱膨脹，進口閥座推向凹槽閥腔內多余的壓力在閥座與閘板之間泄放到管道中。(如圖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.
