力士樂液控單向閥SL10PA1-4X/V
在管路中所使用的閥門品種繁多，結(jié)構(gòu)各異，又是易損壞的管路附件，對每種閥門的檢修，應(yīng)根據(jù)具體結(jié)構(gòu)進(jìn)行。
1：閥體和閥蓋的檢修 閥體和閥蓋是閥門外部的封閉殼體，用以承受介質(zhì)的壓力，操作時(shí)的附加力，閥門其他零件重量，以及連接處法蘭或螺紋的緊力. 閥體和閥蓋要求有一定的強(qiáng)度和剛度，他們的損壞主要是介質(zhì)腐蝕，沖蝕及機(jī)械損傷造成的局部缺陷，當(dāng)因腐蝕或沖蝕造成壁減薄，以至影響到它們的強(qiáng)度和剛度時(shí)，則無法修理，應(yīng)予以更換.
檢修時(shí)，閥體和閥蓋應(yīng)先進(jìn)行水壓強(qiáng)度試驗(yàn)，再用水，壓縮空氣，煤油或其它介質(zhì)檢驗(yàn)其嚴(yán)密性. 閥體和閥蓋的缺陷一般采用補(bǔ)焊的方法，根據(jù)材質(zhì)的不同選用相應(yīng)的焊條和焊接工藝. 焊補(bǔ)前應(yīng)將有缺陷的金屬清洗干凈，補(bǔ)焊后還應(yīng)進(jìn)行檢查和修整，并消除應(yīng)力.
2：填料室的檢修 填料室的檢修包括填料更換和填料函部位檢查修理.選用填料時(shí)，必須考慮使用條件和介質(zhì)情況.一般來說，油侵石棉盤根適用于一定溫度的空氣，蒸汽，水和重油產(chǎn)品.石墨石棉盤根可用于高溫高壓條件下，尤以夾有鋼絲的石墨石棉盤根耐壓力更佳.高溫并且溫度經(jīng)常變化的介質(zhì)可用石棉加鉛盤根.強(qiáng)腐蝕介質(zhì)可用侵聚四氟乙烯石棉盤根或聚四氟乙烯編織.
