截止閥
Stop valve
截止閥的閥桿軸線與閥座密封面垂直。
閥桿開啟或關(guān)閉行程相對(duì)較短，并具有非?？煽康那袛鄤?dòng)作， 使得這種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。
1.截止閥的閥瓣一旦處于開啟狀況，它的閥座和閥瓣密封面之間就不再的接觸，并具有非?？煽康那袛鄤?dòng)作，合得這種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。
2.截止閥一旦處于開啟狀態(tài)，它的閥座和閥瓣密封面之間就不再有接觸，因而它的密封面機(jī)械磨損較小，由于大部分截止閥的閥座和閥瓣比較容易修理或更換密封元件時(shí)無需把整個(gè)閥門從管線上拆下來，這對(duì)于閥門和管線焊接成一體的場(chǎng)合是很適用的。介質(zhì)通過此類閥門時(shí)的流動(dòng)方向發(fā)生了變化，因此截止閥的流動(dòng)阻力較高于其它閥門。

Stem axis and sealing surface are vertical.
It takes stem short time to open and close. Stem with reliable cut-off action is suitable for cutting off media and adjusting and throttling.
1. Seat and disc don’t contact when disc is being opened, and with reliably cutting action to make this kind of valve is suitable for cutting of media and adjusting and throttling.
2. Seat and disc don’t contact when globe valve is being opened makes machinery of sealing surface small wear. Seat and disc are convenient to mended and valve is needn’t to remove from pipeline when changing seals that is suitable for valve and pipeline are welded together. Flow direction is change while media crosses through this kind of valve, so flow resistance of this kind valve is much higher than others.
