球閥的全通徑及縮徑結(jié)構(gòu)
FULL&REDUCE BORE
為滿足客戶的不同需求，球閥設(shè)有全通徑及縮徑兩大系列。全通徑球閥的通道內(nèi)徑與管線內(nèi)徑*，不但流體阻力zui小，也便于管道清理。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，有效的降低了生產(chǎn)成本及價(jià)格，因而遂得到了較為廣泛的使用。
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(jié)構(gòu)
BLOW-OUT PROOF STEM
閥桿采用下裝式設(shè)置帶有密封墊片的倒密封結(jié)構(gòu)，倒密封的密封力隨閥腔介質(zhì)壓力的增高增大，從而確保閥桿的密封效果。當(dāng)閥腔異常升壓時(shí)，閥桿不會被沖出。填料采用設(shè)計(jì)合理的V型結(jié)構(gòu)，能將閥腔內(nèi)部的介質(zhì)壓力及外部壓蓋的鎖緊力有效的轉(zhuǎn)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(jié)構(gòu)，功能和特點(diǎn)
耐火結(jié)構(gòu)
FIRE SAFE SEAT SEALING
根據(jù)用戶的需要，球閥可設(shè)計(jì)成耐火結(jié)構(gòu)，當(dāng)萬一發(fā)生火災(zāi)而使密封圈燒損時(shí)，球閥的各個(gè)密封部位均能形成金屬對金屬的硬密封結(jié)構(gòu)，有效阻止介質(zhì)的擴(kuò)散，防止火災(zāi)擴(kuò)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(jié)構(gòu)
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(dòng)較大的場合手柄受到撞擊易產(chǎn)生誤操作的閥門，在閥門的全開或全關(guān)的位置沒有鎖定孔，需要時(shí)可加鎖，起到安全保險(xiǎn)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(jié)構(gòu)
ANTI-STATIC DEVICE
根u據(jù)用戶需要，球閥可設(shè)計(jì)防靜電結(jié)構(gòu)，即在球體與閥桿，閥桿與閥體之間設(shè)置導(dǎo)電彈簧，使閥門在開啟過程中產(chǎn)生的靜電能通過所設(shè)置的靜電通道傳入管路導(dǎo)入地下，達(dá)到清除靜電的目的。避免靜電打火點(diǎn)燃易燃介質(zhì)，確保系統(tǒng)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.
