I-valve yomzimba ine-trachoma noma i-crack; 2. I-valve yokulungisa umzimba we-welding tensile crack Ukucutshungulwa: 1. Umfantu okusolakala ukuthi uyapholishwa, uqoshwe ngesisombululo se-nitric acid esingu-4%, njengokuqhekeka kungaboniswa; 2. Gcoba futhi ulungise umfantu. Okubili, isiqu se-valve kanye nokulimala kwaso kwentambo yesikulufu esihambisanayo noma ikhanda lesiqu eliphukile, ukugoba kwesiqu se-valve: Isizathu: 1. Ukusebenza okungalungile, amandla okushintsha kukhulu kakhulu, khawulela ukwehluleka kwedivayisi, ukuvikela phezu kwetorque akusebenzi. ; 2. Ukufakwa kwentambo kuxega kakhulu noma kuqine kakhulu; 3. Izikhathi zokusebenza eziningi kakhulu nempilo yesevisi ende kakhulu Ukucutshungulwa: 1. Thuthukisa ukusebenza futhi ungasebenzisi amandla amaningi; Hlola idivayisi yomkhawulo, hlola idivayisi yokuvikela i-torque; 2. Khetha izinto ezifanele futhi uhlangabezane nezidingo zokubekezelela umhlangano; 3. Faka esikhundleni izingxenye eziyisipele Ezintathu, ukuvuza okuhlangene kwekhava yevalvu: Imbangela: 1. Amandla okuqinisa ibholidi awanele noma ukuchezuka okuqinile; 2. I-gasket ayihlangabezani nezidingo noma yonakele; 3. Indawo yokubopha engalungile Ukucutshungulwa: 1. Qinisa ibhawodi noma wenze ukuvuleka kwe-flange kwekhava yomnyango kuhambisane; 2. Faka esikhundleni i-gasket; 3. Hlukanisa futhi ulungise indawo evalekile yekhava yomnyango Okwesine, ukuvuza kwamavalvu: Isizathu: 1. Ukuvaleka okuxekethile; 2. Ukonakala kwendawo yokubopha; 3. Igebe phakathi kwe-spool ye-valve nesiqu se-valve likhulu kakhulu, okuholela ekuweni noma ukuthintana kabi kwe-valve spool; 4. Impahla yokuvala ayilungile noma i-spool ibambekile. Iyacubungula: 1. Thuthukisa ukusebenza, qala kabusha noma uvale; 2. I-valve iyahlakazeka, futhi indawo yokuvala ye-valve core kanye nesihlalo siphansi; 3. Lungisa igebe phakathi kwe-spool nesiqu noma shintsha idiski; 4. I-valve disassembly, susa ukunamathela; 5. Faka esikhundleni noma ukubeka indandatho yokuvala Okuhlanu, i-spool kanye ne-valve stem, okuholela ekuhlulekeni kokushintsha: Isizathu: 1. Ukulungiswa okungalungile; 2. Ilunga le-spool nesiqu ligqwalile; 3. Amandla okushintsha makhulu kakhulu, okuholela ekulimaleni kwelunga phakathi kwe-spool nesiqu se-valve; 4. I-spool stop gasket ixega futhi ingxenye yokuxhuma iyagqokwa Iyacutshungulwa: 1. Qaphela ukuhlolwa ngesikhathi sokulungiswa; 2. Buyisela induku yesicabha ngezinto ezikwazi ukumelana nokugqwala; 3. Ukusebenza akukona ukushintshwa okuqinile, noma akuvuleki ngokugcwele ngemva kokuqhubeka nokuvula ivalvu; 4. Hlola bese ubuyisela izingxenye ezilimele eziyisipele Isithupha, umgogodla wevalvu, ukuqhekeka kwesihlalo: Isizathu: 1. Izinga eliphansi lokuvela endaweni ehlangene; 2. Ukwelashwa komehluko omkhulu wokushisa phakathi kwezinhlangothi ezimbili zevalve: Lungisa ukushisela kwemifantu, ukwelashwa kokushisa, ukupholisha nokugaya ngokuvumelana nemithethonqubo. Isikhombisa, i-valve stem lift noma iswishi ayinyakazi: Isizathu: 1. Uma kubanda, ivaleka kakhulu ngemva kokushisisa, noma iqine kakhulu ngemva kokuvuleka ngokugcwele; 2. Ukupakisha kucindezelwe kakhulu; 3. I-valve stem clearance incane kakhulu futhi ifile iqhubu; 4. Isiqu se-valve siqine kakhulu nge-screw, noma i-screw buckle yonakalisiwe; 5. Ukupakisha ukuchezuka kwengcindezi yegland; 6. Ukugoba kwenduku yomnyango; 7 izinga lokushisa eliphakathi nendawo liphezulu kakhulu, ukugcotshwa okungalungile, ukugqwala okukhulu kwesiqu se-valve Ukucutshungulwa: 1. Ngemva kokufudumeza umzimba wevalvu, zama ukuwuvula kancane noma ukuwuvala kancane lapho usuvuleke ngokugcwele futhi uqinile; 2. Khulula indlala yokupakisha kancane bese uzama ukuyivula; 3. Khulisa ukususwa kwesiqu ngokufanele; 4. Faka esikhundleni isiqu se-valve nesikulufu; 5. Lungisa ibhawodi lendlala yokupakisha; 6. Qondisa noma ubuyisele induku yesicabha; 7. Induku yomnyango yenziwe nge-graphite powder emsulwa njengamafutha Esishiyagalombili, ukuvuza okupakisha: Isizathu: 1. Izinto zokugcwalisa akulungile; 2. Indlala yokupakisha ayicindezelwa ngokuqinile noma ichemile; 3. Indlela yokupakisha ayilungile; 4. Ukulimala kobuso besiqu Ukucutshungulwa: 1. Ukukhetha kahle kokugcwalisa; 2. Hlola futhi ulungise indlala yokupakisha ukuze uvimbele ukuchezuka kwengcindezi; 3. Faka ukupakisha ngokwendlela efanele; 4. Lungisa noma shintsha isiqu se-valve esihlinzekwe umnyango wezobuchwepheshe we-Sanjing valve Ship engine room valve supplier Isingeniso: I-Shanghai Taichen Valve Co., Ltd. ingumkhiqizi ochwepheshile wamavalvu aseMarine. Ibhizinisi lethu lihlanganisa zonke izingxenye zezwe futhi linesimo esithile somkhiqizo e-Shanghai. Imikhiqizo yethu ye-valve yase-Marine ikhiqizwa ngokuhambisana ngokuqinile nezinga likazwelonke (GB), izinga lemboni yasolwandle (CB), izinga laseJapane (JIS), izinga lesiJalimane (DIN), i-American Standard (ANSI). Imikhiqizo yasolwandle esiyimbozayo amavalvu ovemvane, amavalvu esango, ama-ball valve, ama-globe valves, ama-sheke valve nama-Angle valve. Ukwethulwa kokubalulekile kwevalvu egumbini lenjini: Ivalvu yakhiwe izingxenye ezimbili zendlela yokulawula kanye nomzimba we-valve, impahla evame ukusetshenziswa yevalvu inezinhlobo ezine. 1, insimbi eyinsimbi: izinga lokushisa le-valve yensimbi lingama-degree angama-125, futhi kulula ukugqwala. Ifanele indle nezinye imidiya. 2, cast steel: cast steel valve izinga lokushisa lingafinyelela degrees 425, ukusetshenziswa high lokushisa medium. I-3, insimbi engagqwali: i-valve yensimbi engagqwali inendima yokumelana nokugqwala nokumelana nokushisa okuphezulu, ifanele izimo ezahlukahlukene eziyinkimbinkimbi. I-4, i-alloy steel: i-alloy steel valve material ngaphezu kwe-iron, i-carbon, kodwa futhi yengeza ezinye izakhi ze-alloy, ezisetshenziswa ezindaweni ezihlukahlukene zokushisa eziphakeme neziphansi. Isithombe secala lokusebenzisa i-valve yegumbi lenjini yomkhumbi: Indlela yokunakekela i-valve yomkhumbi: 1. Indlela yokulungisa i-valve yasolwandle: Ukugcinwa kwe-valve yasolwandle kungahlukaniswa ngokulungiswa okuphuthumayo, ukugcinwa okuvamile kanye nokugcinwa kokubikezela. Ukugcinwa kwezimo eziphuthumayo kusekuhlulekeni kwe-valve, akukwazi ukuhlangabezana nezidingo zokusebenza kwenqubo lapho ukugcinwa. Ukugcinwa okuhleliwe kuvame ukuhlanganisa ukugcinwa nokugcinwa okujwayelekile okuhambisana nokulungiswa kabusha kwenqubo yokumiswa. Ukugcinwa kokubikezela kusekelwe emiphumeleni yokuhlaziya yokulungiswa okubikezelwayo, ukugcinwa okuhlosiwe kwezingxenye ezifanele zama-valve okulawula. Ukugcinwa okuphuthumayo ukugcinwa ngemuva kokuhluleka kwe-valve elawulayo, ukugcinwa okuvamile kanye nokugcinwa kokubikezela ukugcinwa ngaphambi kokuhluleka kwe-valve. Imvamisa, ukunakekelwa okujwayelekile kwama-valve aseMarine kwenziwa ngabasebenzi abalungisa izinsimbi, futhi ukugcinwa okuvamile okuhambisana nokulungisa kabusha kwenziwa ochwepheshe bokukhiqiza. Izingxenye ezisengozini ze-valve ikakhulukazi: ukupakisha, indandatho yokuvala, i-gasket, indandatho yokuvala i-piston, i-diaphragm, isihlalo esithambile, i-spool sealing liner. Ngaso sonke isikhathi ukulungiswa kuzoshintshwa izingxenye ezintsha. Okwesibili, indlela yokunakekela nsuku zonke yevalvu yasemanzini: 1. Buza umqhubi wenqubo osemsebenzini mayelana nokusebenza kwevalvu. 2. Hlola amandla okunikezwayo (uwoyela we-hydraulic air noma amandla kagesi) amavalvu Asolwandle nezinye izinto ezihlobene. 3. Hlola ukusebenza kwesistimu kawoyela we-hydraulic. 4. Hlola izindawo zokuvala ezimile neziguquguqukayo zevalvu ukuthi azivuzi yini. 5. Hlola ukuthi imigqa yokuxhuma i-valve nezixhumi zixega noma zigqwalile. 6. Hlola ukuthi ingabe ivalvu inomsindo ongajwayelekile kanye nokudlidliza okukhulu, bese uhlola isimo sokuhlinzeka. Hlola ukuthi isenzo se-valve siyavumelana yini nokuthi siyashintsha yini ngesikhathi lapho isignali yokulawula ishintsha 8. Lalela ukudlidliza okungavamile noma umsindo wesihlalo se-spool. 9. Uma inkinga itholakele, xhumana nomsebenzisi ukuze uyibambe. 10. Yenza irekhodi lokuhlolwa kokuvakasha bese ulifayela.
