Ama-valve embulunga yensimbi eyenziwe ngomgunyathi zihlukaniswe zibe ama-valve embulunga yensimbi eyenziwe nge-carbon steel futhi ama-valve embulunga yensimbi engenasici, ngokuvamile asetshenziswa ezikhathini zokucindezela okuphezulu nokuphakathi (150lb-800lb, 1500LB, 2500LB), kanye nezikhathi zokushisa eziphakeme neziphansi (-196℃ ~ 700℃), amavalvu ensimbi akhiwe anamandla aphezulu kanye nezakhiwo ezingcono zemishini ukuhlangabezana nengcindezi ephakeme. izidingo. Kodwa kunqunyelwe inqubo yokubumba, ngokuvamile kusebenza kuphela kusayizi omncane nophakathi (1/2 “, 3/4 “, 1 “, 1-1/4 “, 1-1/2 “, 2, 2-1/2 ", 3" futhi 4 "). I-Valve Operation ingaba imanuwali, igiya le-bevel, i-pneumatic actuator, i-actuator kagesi, i-hydraulic actuator, i-pneumatic-hydraulic, i-electro-hydraulic.

Izinzuzo zesakhiwo se-valve yensimbi ye-Newsway Valve zimi kanje:

1. I-valve yeglobu yensimbi eyenziwe ngomgunyathi isebenzisa uphawu oluziqinisayo, futhi zombili iziphetho zepayipi legatsha lomzimba we-valve ziyashiselwa.

2. Isihlalo se-valve ye-globe yensimbi esakhiwe, i-valve disc sealing surface yenziwe nge-cobalt-based cemented carbide spray spray welding, ukumelana nokugqoka, ukumelana nokuhuzuka okuphezulu.

3. Isiqu se-valve siphathwa nge-nitriding ukumelana nokugqwala, enokumelana nokugqwala okuhle nokumelana nokuhuzuka.

4 ohlelweni lokuvula nokuvala, ngenxa ye-valve disc ku-valve body sealing surface friction incane, futhi ukumelana nokugqoka.

5. Imvamisa kunobuso obubodwa bokuvala emzimbeni we-valve kanye ne-disc, ngakho-ke inqubo yokukhiqiza ingcono futhi ilungele ukulungiswa.

I-valve kufanele ihlolwe ngaphambi kokufakwa, futhi izinga lokuklama i-valve kufanele lihambisane ne-API 602 evamile yamazwe ngamazwe. Ukuhlolwa kokusebenza kwamandla nokuqina kufanele kwenziwe ngaphambi kokufakwa. Ekuhlolweni kwamandla, ukucindezela kokuhlola izikhathi ezingu-1.5 zokucindezela okulinganiselwe, futhi ubude besikhathi abukho ngaphansi kuka-5min. Igobolondo le-valve nokupakisha kufanele kuqeqeshwe ngaphandle kokuvuza. Ukuhlolwa kokubeka uphawu, ingcindezi yokuhlola izikhathi eziyi-1.1 zokucindezela okuzisholo; Ingcindezi yokuhlola ngesikhathi sobude besikhathi sokuhlola kufanele ihlangabezane nezimfuneko ze-API 598 ejwayelekile, ngaphandle kokuvuza endaweni yokuvala i-disc njengokufanelekile.
