介質溫度不高時為2°52'。楔式閘閥的閘板可以做成一個整體，叫做剛性閘板；也可以做成能產生微量變形的閘板,以改善其工藝性,彌補密封面角度在加工過程中產生的偏差,這種閘板叫做彈性閘板。閘閥的安裝維護注意事項： 1.手輪、手柄及傳動機構均不允許作起吊用，并嚴禁碰撞。 2. 雙閘板閘閥應垂直安裝（即閥桿處于垂直位置 , 手輪在頂部）。 3. 帶有旁通閥的閘閥在開啟前應先打開旁通閥（以平衡進出口的壓差及減小開啟力）。 4. 帶傳動機構的閘閥，按產品使用說明書的規(guī)定安裝。 5. 如果閥門經常開關使用 , 每月至少潤滑一次。ＷＣ９電站閘閥價格閘閥閥體內部介質通道是直通的，介質流經閘閥時不改變其流動方向，因而流動阻力較小。</p><div style="width:100%;text-align: center;"><img

1、產品的設計制造符合美國國家標準ANSI B16.34，美國石油學會標準API6D和API600要求。 2、結構緊湊、體積小、剛性好、密封安全可靠。 3、關閉件(閘板)采用彈性結構，在工作中能自動補償由于異常負荷或溫度引起的閥體變形。因此，密封可靠，并且不會產生閘板楔柱。 4、通徑大于等于NPS10"，壓力級150磅級和通徑大于等于NPS6"、壓力級600~2500磅級的手動閥門，其操作裝置中配有滾動軸承，啟閉輕松。 5、主體材料，內件材料，填料，墊片、緊固件的材料可根據用戶要求或實際工況條件合理組合。 6、NPS≤10"的閘閥，其閥座可為更換式內螺紋連接的閥座，可任意組合與關閉件密封面材質配對，以滿足工況要求，延長使用壽命。</p><p style="text-indent:25px">美標閘閥適用于 ANSI Class150~2500、PN20~42、JIS10~20K，工作溫度 -29~425℃（碳鋼）及
