球閥的主要結構功能和特點

    球閥的全通徑及縮徑結構

    FULL&REDUCE BORE

     為滿足客戶的不同需求，球閥設有全通徑及縮徑兩大系列。全通徑球閥的通道內徑與管線內徑一致，不但流體阻力最小，也便於管道清理。而縮徑球閥的流體阻力比相同口徑截止閥的流體阻力要低很多，重量比相同口徑的球閥要輕30%左右，有效的降低瞭生產成本及價格，因而遂得到瞭較為廣泛的使用。

In order to meet different needs of customers,we provide two serries of ball valves ,full bore and reduced bore ball valve .The channel inner diameter of full bore ball valves is consistent with the inner diameter of pipeline,which can not only minimize the fluid resistance but also facilitate pipeline cleaning.The fluid resistance of necked bore ball valves is much less than that of the globe valve with the same caliber while its weight is 30%lighter than ball valve with the same caliber .As result ,it can effectively reduce both the production cost and price ,and is relatively widely uesd.

          閥桿防沖出及有效密封結構

      BLOW-OUT PROOF STEM

      閥桿采用下裝式設置帶有密封墊片的倒密封結構，倒密封的密封力隨閥腔介質壓力的增高增大，從而確保閥桿的密封效果。當閥腔異常升壓時，閥桿不會被沖出。填料采用設計合理的V型結構，能將閥腔內部的介質壓力及外部壓蓋的鎖緊力有效的轉化成閥桿的密封力。     The stem is downloading ,with its inverted sealingstructure with sealing gasket.The fore of inverted sealing struct willincrease while the medium pressure in the valve cavity increasing of the valve cavity increases to ensure the sealing effect of the stem. In case of abnormal pressure increasing of the valve cavity ,the stem won’t be impacted out .The filler is designed with proper V-shaped structure,which can effectively conver the medium pressure inside the valve cavity and the locking force of outer gland into the sealing force of stem.

               閥門的主要結構，功能和特點

    耐火結構

    FIRE SAFE SEAT SEALING

      根據用戶的需要，球閥可設計成耐火結構，當萬一發生火災而使密封圈燒損時，球閥的各個密封部位均能形成金屬對金屬的硬密封結構，有效阻止介質的擴散，防止火災擴大。

 According to the user's requirement,the ball valve can be designed with fire-resistant stucture.In case of a fire and the sealing ring is damaged,every sealing part of the ball valve can form the structure of metal-to-metal hard seal,which can prevent the spreading of both the media and fire.

     帶鎖結構

     INTERLOCKING DEVICE

      對安裝在野外的或防止非工作人員誤操作的，以及在有些震動較大的場合手柄受到撞擊易產生誤操作的閥門，在閥門的全開或全關的位置沒有鎖定孔，需要時可加鎖，起到安全保險作用。

      For valve installed outdoor,those preventing improper operation of non-workers and valves,of which collision of its stem in relatively violent vibration occasions easily causes improper operation,a locking bore can be set in the fully open position or fully closed position and a lock can be used if needed,for the purpose of security insurance.

     防靜電結構

     ANTI-STATIC DEVICE

      根u據用戶需要，球閥可設計防靜電結構，即在球體與閥桿，閥桿與閥體之間設置導電彈簧，使閥門在開啟過程中產生的靜電能通過所設置的靜電通道傳入管路導入地下，達到清除靜電的目的。避免靜電打火點燃易燃介質，確保系統安全。

      According to the user's requirement,the ball valve can be designed with anti-static structure;namely,fix the conductive spring between the ball and stem as well as stem and valve body,to enable the static generated when opening the valve to be transmitted to the pipeline through static channel and conducted underground and finally eliminate the static.It can prevent the static ignition form lighting the medium to ensure safety of the system.
