Ukufakwa kwevalvu elawula ugesi kanye nokulungisa iphutha Isignali yevalvu elawula ugesi ehambisana nokuvuleka kwevalvu Ukufakwa nokulungisa ama-valve kagesi Ngaphambi kokufakwa kwevalvu yokulawula kagesi kufanele ifunde ngokucophelela ikhophi, ukunikezwa kwamandla okufanelekile futhi kufanele kufakwe abasebenzi abangochwepheshe nabezobuchwepheshe. Isiqondiso sokugeleza kufanele sibe ohlangothini olufanayo nomcibisholo osemzimbeni we-valve. I-valve yomzimba kufanele ibe ngaphezu kwepuleti elamukela amanzi lekhoyili ukuze kuqinisekiswe ukuthi amanzi awela epuleti lokwamukela amanzi. Umzimba we-valve nomshayeli kufanele kufakwe endaweni eqondile yobubanzi obungu-60℃, okungenhla kufanele okungenani kube isikhala esingu-30mm sokuqaqa. Indawo yokuqondisa eyanele kufanele inakekelwe ngamapayipi, izinto zokusebenza nezakhiwo eziseduze, futhi kufanele kufakwe lapho abasebenzi abalungisayo bekwazi ukufinyelela khona ngezimbobo zokuhlola. Faka umshayeli kuphela ngemva kokuba umzimba we-valve usufakiwe futhi ipayipi seliphumelele ukuhlolwa komfutho. Uma umshayeli efakwe emzimbeni we-valve, ungasebenzisi amandla kumshayeli ngesikhathi sokufakwa nokuthunywa, ngaphandle kwalokho umshayeli uzolimala. Ngemva kokufaka futhi uhlole ukunemba, ukulungisa iphutha kwamandla. Okungenani imijikelezo emithathu yokusebenza ephelele yomshayeli kufanele ibhekwe kuze kube yilapho zonke izingxenye zinembile. Ngemva kokuphumelela ukuhlolwa kwamanzi, ukuhlolwa kwamanzi kuzokwenziwa. Umehluko wengcindezi phakathi kwamanzi angaphezulu naphansi ohlelo kufanele ulawulwe ngokuqinile ngaphakathi kwe-0.15MPa ukuze kuqinisekiswe ukusebenza kahle kwe-valve yokulawula kagesi ekushintsheni kokugeleza kwamanzi. Isignali yevalvu elawulayo kagesi ehambisana nokuvuleka kwevalvu Isignali yevalvu elawulayo kagesi ehambisana nokubuka kuqala ukuvulwa kwevalvu: Ivalvu elawula ugesi ngokwamukela ithuluzi lokulawula elisuka kusignali engu-4-20MA, ukuze kuqedelwe ukulawula okuphakathi epayipini, ukugeleza, izinga lokushisa. Ngakho-ke kungakanani ukuvulwa kwe-valve okuhambisana nesignali yamanje ye-4-20MA, futhi iyiphi indlela yokuguqula? I-valve yokulawula kagesi ithole isignali kanye nendlela yokuguqula evulekile: lapho i-valve yokulawula kagesi yokwamukela isignali yamanje ingaphansi noma i-4MA lapho i-valve ivaliwe. Ukuvulwa kwevalvu kungu-6.25% uma isignali eyamukelayo ingu-5MA. Indlela yokuguqula iwukukhipha isignali ye-20MA kusignali evaliwe ye-4MA, okuyisignali evuliwe ye-16MA. Ukuvulwa kwevalvu yokulawula engcono kakhulu ehlukaniswe ngokuvulwa kwesignali engu-16MA etholwe ingekho isignali evulekile ye-MA ingu-6.25%. Isignali ye-valve yokulawula kagesi ehambisana nencazelo yokuvula i-valve: Okusho ukuthi, uma isignali yamanje ingu-8MA, i-valve ivulwa ngekota eyodwa futhi ukuvulwa kungu-25%; Uma isignali yamanje ingu-12MA, isigamu se-valve sivuliwe, futhi i-degree yokuvula i-50%. Lapho isignali yamanje ingu-16MA, i-valve ivuliwe izingxenye ezintathu kwezine, futhi ukuvulwa kungu-75%; Lapho isignali yamanje ingu-20MA, i-valve isesimweni esivulekile ngokugcwele futhi idigri yokuvula ingu-100%. Ulwazi lobuchwepheshe lwevalvu yokulawula engenhla ngumkhiqizi wamavalvu okulawula ochwepheshe wase-Shanghai - i-Shanghai Taichen Valve Co., LTD.
