Lungisa okanye utshintshe isiqu sevalve ebonelelwe lisebe lobugcisa le-Sanjing valve Umthengisi wegumbi le-injini ye-injini Intshayelelo: I-Shanghai Taichen Valve Co., Ltd. ngumenzi oqeqeshiweyo weevalvu zaseLwandle. Umda weshishini lethu ugubungela zonke iindawo zelizwe kwaye unesimo sohlobo oluthile eShanghai. Iimveliso zethu zevalve yaseLwandle zenziwa ngokungqongqo ngokuhambelana nomgangatho wesizwe (GB), umgangatho woshishino lwaseLwandle (CB), umgangatho waseJapan (JIS), umgangatho waseJamani (DIN), uMgangatho waseMelika (ANSI). Iimveliso zaseLwandle esizigqumayo ziivalvu zebhabhathane, iivalvu zesango, iivalvu zebhola, iivalve zeglowubhu, iivalve zetshekhi kunye neeAngle valves. Ukwaziswa kwezinto zevalve kwigumbi le-injini: Ivalve yenziwe ngamacandelo amabini omatshini wokulawula kunye nomzimba wevalvu, izinto ezisetyenziswa ngokuqhelekileyo kwivalve zineentlobo ezine. 1, intsimbi yokuphosa: iqondo lobushushu levalve yentsimbi limalunga ne-125 degrees, kwaye kulula ukurusa. Ifanele amanzi amdaka kunye nezinye imidiya. 2, intsimbi ephosiweyo: iqondo lobushushu levalvu yentsimbi inokufikelela kuma-425 degrees, ukusetyenziswa kobushushu obuphakathi. I-3, insimbi engenasici: i-valve yensimbi engenasici inendima yokumelana ne-corrosion kunye nokumelana nokushisa okuphezulu, okufanelekileyo kwiimeko ezahlukeneyo ezinzima. I-4, intsimbi ye-alloy: i-alloy steel valve i-alloy material ngaphezu kwesinyithi, i-carbon, kodwa iphinde yongeze ezinye izinto ze-alloy, ezisetyenziselwa kwiindawo ezahlukeneyo zokushisa eziphezulu kunye nezantsi. Umfanekiso wecala lokusetyenziswa kwevalve yegumbi le-injini yenqanawa: Indlela yokugcina ivalve yenqanawa: 1. Indlela yokugcinwa kwevalve yaselwandle: Ukugcinwa kwevalve yaselwandle kunokwahlulwa kulondolozo olungxamisekileyo, ukugcinwa rhoqo kunye nokugcinwa kwangaphambili. Ukugcinwa okungxamisekileyo kukungaphumeleli kwevalve, ayikwazi ukuhlangabezana neemfuno zokusebenza kwenkqubo xa ukugcinwa. Ulondolozo olucwangcisiweyo ludla ngokubandakanya ugcino lwesiqhelo kunye nokugcinwa ngokuhambelana nenkqubo yokunqunyanyiswa ngokutsha. Ugcino oluqikelelwayo lusekwe kwiziphumo zohlalutyo logcino oluqikelelweyo, ugcino olujolisiweyo lweendawo ezifanelekileyo zevalvu elawulayo. Ukugcinwa okungxamisekileyo kukugcinwa emva kokungaphumeleli kwevalve elawulayo, ukugcinwa rhoqo kunye nokugcinwa kwangaphambili kukugcinwa phambi kokungaphumeleli kwevalve. Ngokuqhelekileyo, ukugcinwa kwesiqhelo kweevalve zaseLwandle kuqhutyelwa ngabasebenzi bokugcinwa kwesixhobo, kwaye ukugcinwa rhoqo kunye nokulungiswa kwenziwa ngabachwephesha bokuvelisa. Iindawo ezisesichengeni zevalve ikakhulu: ukupakisha, umsesane wokutywina, i-gasket, umsesane wokutywina wepiston, i-diaphragm, isitulo esithambileyo sokutywina, ilineni yokutywina ye-spool. Ngalo lonke ixesha ulondolozo luya kutshintshwa ngamalungu amatsha. Eyesibini, indlela yokugcinwa kwevalve yemihla ngemihla: 1. Buza umqhubi wenkqubo osemsebenzini malunga nokusebenza kwesivalo. 2. Qwalasela amandla obonelelo (i-oyile yokwenziwa koxinzelelo lomoya okanye unikezelo lwamandla) lweevalvu zaseLwandle kunye nezincedisi ezinxulumeneyo. 3. Jonga ukusebenza kwenkqubo yeoli yehydraulic. 4. Qwalasela iindawo zokutywina ezimileyo neziguqukayo zevalve ukuba ivuza. 5. Khangela ukuba imigca yoqhagamshelo lwevalve kunye nezihlanganisi zikhululekile okanye zidliwe. 6. Khangela ukuba ivalve inesandi esingaqhelekanga kunye nokungcangcazela okukhulu, kwaye ujonge imeko yokubonelela. Khangela ukuba isenzo sevalve siguquguqukayo kwaye sitshintshe ngexesha xa isignali yokulawula itshintsha 8. Mamela ukungcangcazela okungaqhelekanga okanye ingxolo yesitulo se-spool. 9. Ukuba ingxaki ifunyenwe, qhagamshelana nomsebenzisi malunga nokusingatha. 10. Yenza irekhodi yohlolo lokhenketho kwaye uyifayilishe.
