It is necessary to comprehensively check the wear of the valve core and valve seat of the power station valve, polish minor scratches, and replace them if there is serious deformation.<br \/>\n2. Use an endoscope to detect 0.1mm internal corrosion, with an accuracy similar to that of a medical gastroscope.<br \/>\n[Pressure test]<br \/>\nA 1.5 times working pressure test is required, and the pressure holding time is \u226530 minutes\u200c.<br \/>\nThese systematic maintenance can extend the service life of power station valves from ten years to thirty years.<\/p>\n<p><img decoding=\"async\" class=\"alignleft size-full wp-image-8599\" src=\"http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704.jpg\" alt=\"\" width=\"400\" height=\"400\" srcset=\"http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704-66x66.jpg 66w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704-150x150.jpg 150w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704-200x200.jpg 200w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704-300x300.jpg 300w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2025\/03\/279242704.jpg 400w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Daily main [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":8599,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[61],"tags":[899],"acf":[],"_links":{"self":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/8598"}],"collection":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=8598"}],"version-history":[{"count":1,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/8598\/revisions"}],"predecessor-version":[{"id":8600,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/8598\/revisions\/8600"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/media\/8599"}],"wp:attachment":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=8598"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=8598"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=8598"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
