即使在理想的實(shí)驗(yàn)室測(cè)試環(huán)境下，不考慮法蘭光潔度和密封墊負(fù)載，API 600
所規(guī)定的沒有石墨的標(biāo)準(zhǔn)密封墊也被認(rèn)為不適用于低排放場(chǎng)合。在測(cè)試了幾種替代
密封墊后，我們選擇了在我們的測(cè)試中表現(xiàn)性能的密封墊 - 帶石墨填料通路
的波紋鋼板密封墊。
Standard corrugated steel gaskets without graphite as specified in API 600 were found to be an unacceptable choice for low emission service, even under ideal laboratory test conditions, and regardless of flange finish and gasket load. After testing several alternative gaskets, we selected the best performing gasket in our tests - a corrugated steel gasket with graphite filled channels.
API 600 鑄鋼閘閥概述 及使用材料
- 更安全、更緊密地閥桿密封。
Safer and tighter stem seal. - 又短又窄的填料腔改善了密封性能。
Short and narrow packing chamber improves sealing effectiveness. - 配置雙填料和無泄漏的長(zhǎng)壽命防泄漏填料腔或單填料。
雙填料：經(jīng)過4000 psi壓縮的兩套石墨填料密封環(huán)。也可選擇一個(gè)套環(huán)和leak-off，用于消除泄漏現(xiàn)象。
單填料：在編織環(huán)之間放置三個(gè)或四個(gè)石墨環(huán)，密度80-90磅/立方英尺。
Long-life leakproof packing chamber with double packing and leak-off or single set packing.
Double packing: two sets of graphite packing rings compressed to 4000 psi. A lantern ring and leak-off provide option for removal of leakage, if any, from lower packing set.
Single set packing: three or four graphite rings between braided rings, 80-90 lbs./cu. ft. density. - 動(dòng)負(fù)載。
兩套免維護(hù)長(zhǎng)期保持閥桿緊密性的Belleville彈簧。
Live-loading.
Two sets of Belleville springs keep stem tight for long periods of time without maintenance. - 兩件式閥桿驅(qū)動(dòng)可在線更新。
Two-piece stem drive is renewable in-line. - 更有效的防泄漏閥體-閥帽連接。
150磅級(jí)：石墨填充波紋鋼板密封墊。
300-600磅級(jí)：全封閉螺旋纏繞石墨填充不銹鋼密封墊。
Stronger leakproof body-bonnet joint.
Class 150: Corrugated graphite-filled steel gasket.
Class 300-600: Fully-encased spiral wound graphite-filled stainless steel gasket. - 300，600，900和1500磅級(jí)配置圓形閥帽和封閉密封墊。
Classes 300, 600, 900 and 1500 have round bonnet and encased gasket
鎢鉻鈷合金6硬面的焊接裝配閥座。
Welded-in seats hardfaced with Slite 6. - 柔性一件式楔板，采用鎢鉻鈷合金6或13 CR硬面（DN200以上采用實(shí)心13 CR）。
Flexible one-piece wedge, hardfaced with Slite 6 or 13 CR （solid 13 CR up to 8"）. - 13 CR硬化的閥桿，接近鏡面的拋光度，延長(zhǎng)填料的使用壽命。
13 CR hardened stem with mirror-like, burnished finish for longer packing life
