Kwenziweivalvus kufanele badlule ekuhlolweni okuhlukahlukeneko kokusebenza, okuqakatheke khulu kikho kuhlolwa komfutho. Ukuhlolwa kwengcindezi kuhlola bona inani lomtjhini ivalvu elikwazi ukujamelana nalo liyahlangabezana na neemfuneko zemithetho yokukhiqiza.Ku-TWS, iivalvu yevithamini ehlezi ethambileko, kufanele ithwalwe ukuhlolwa kokuqina kwesihlalo okuphezulu. Umfutho otjhiwo ngeenkhathi ezi-1.5 ze-PN uzakusetjenziswa emanzini wokuhlola.
Amagama aqakathekileko：Ukuhlolwa kokugandeleleka;I-Soft Seated Butterfly Valve; Ukuhlolwa kokuqina kwesihlalo sokugandeleleka
Ngokuvamileko, ukuhlolwa komfuthoamavalvukufanele alandele iinkambisolawulo ezilandelako namagadango wokuzivikela:
(1) Ngokuvamileko, iivalvuayikho ngaphasi kokuhlolwa kwamandla, kodwanaivalvuumzimba nebhonethi ngemva kokulungisa nofanaivalvuumzimba nebhonethi enomonakalo wokugqwala kufanele ihlolwe ukuqina. Nge-valve yokuphepha, umfutho wayo ongaguqukiko, umfutho wokubuyisela kabutjha nezinye iinhlahlubo kuzokukhambisana nokucaciswa kwemiyalo yayo nemithetho efaneleko.
(2) Ukuhlolwa kwamandla nokuqina kufanele kwenziwe ngaphambi kokuthiivalvuifakiwe. Ama-20% wamavalvu we-low-pressure ahlolwa, begodu ama-100% wawo kufanele ahlolwe nangabe awafaneleki; I-100% yamavalvu aphakathi nendawo naphezulu kufanele ahlolwe.
(3) Ngesikhathi sokuhlolwa, indawo yokufakaivalvukufanele kube ngendlela lapho ukuhlola kulula khona.
(4) Ngobaamavalvungendlela yokuhlanganiswa okuhlanganisiweko, nangabe ukuhlolwa komfutho wepuleti engabonakaliko angeze kwasetjenziswa, isivalo se-conical nofana isivalo se-O-ring singasetjenziselwa ukuhlolwa komfutho. (5) Khipha umoya wevalvu ngendlela ongakghona ngayo ngesikhathi sokuhlolwa kwamanzi.
(6) Umfutho kufanele ukhuphulwe kancanikancani ngesikhathi sokuhlolwa, begodu ukugandeleleka okubukhali nokuzumako akukavunyelwa.
(7) Isikhathi sokuhlolwa kwamandla nokuhlolwa komhlobo wokuvala ngokuvamileko kuba yimizuzu emi-2-3, begodu amavalvu aqakathekileko nakhethekileko kufanele athathe imizuzu emi-5. Isikhathi sokuhlolwa kwamavalvu amancani singaba sifitjhani, begodu isikhathi sokuhlolwa samavalvu amakhulu singaba side. Ngesikhathi sokuhlolwa, nangabe ungabaza, isikhathi sokuhlolwa singangezelelwa. Ngesikhathi sokuhlolwa kwamandla, ukujuluka nofana ukuvuza kweivalvuumzimba nebhonethi akukavunyelwa. Ukuhlolwa kokuvala kwenziwa kanye kwaphelaamavalvu, kanye namavalvu wokuphepha, umfutho omkhuluamavalvunezinye izinto eziqakathekilekoamavalvu. Ngesikhathi sokuhlolwa, ukuvuza okuncani kuvunyelwe emavalvuni angakaqakatheki anomfutho ophasi kanye nobubanzi obukhulu kanye namavalvu anemithetho yokuvumela ukuvuza; ngebanga leemfuneko ezihlukileko zamavalvu jikelele, amavalvu wesiteshi samandla, amavalvu welwandle namanye amavalvu, iimfuneko zokuvuza kufanele zibe ngalendlela elandelako: Yenza ngokuya kwemithetho efaneleko.
(8) Ivalvu ye-throttle ayihlolwa ukuqina kwengcenye yokuvala, kodwana ukuhlolwa kwamandla nokuhlolwa kokuqina kwepaki ne-gasket kufanele kwenziwe. (9) Ngesikhathi sokuhlolwa kwengcindezi, amandla wokuvala wevalvu avunyelwe ukuvalwa ngamandla womuntu oyedwa ajayelekileko; akukavunyelwa ukusebenzisa amandla ngamathulusi afana nama-lever (ngaphandle kwe-torque wrench). Lokha ububanzi besondo lesandla bukhulu nofana bulingana nama-320mm, abantu ababili bavunyelwe ukusebenza ndawonye. ukuvalwa.
(10) Emavalvu anesivalo esiphezulu, ukupakisha kufanele kukhishwe ukuze kuhlolwe ukuqina. Ngemva kokuthi isivalo esiphezulu sivalwe, qala bona akuvuzi na. Nawusebenzisa igesi njengokuhlolwa, hlola amanzi ebhokisini lokugcwalisa. Lokha nawenza ukuhlolwa kokuqina kokupakisha, isivalo esiphezulu asivunyelwe ukuba sebujameni obuqinileko.
(11) Kiyo nanyana ngiyiphi ivalvu enesisetjenziswa sokutjhayela, lokha nakuhlolwa ukuqina kwayo, isisetjenziswa sokutjhayela kufanele sisetjenziselwe ukuvala ivalvu begodu kwenziwe ukuhlolwa kokuqina. Ngedivayisi eqhutshwa ngesandla, ukuhlolwa kokuvala kwevalvu evalwe ngesandla nakho kuzokwenziwa.
(12) Ngemva kokuhlolwa kwamandla nokuhlolwa kokuqina, i-valve yokudlula efakwe ku-valve ekulu izakuhlolwa ukuqina nokuqina ku-valve ekulu; lokha ingcenye yokuvala yevalvu ekulu nayivulwa, nayo izokuvulwa ngokufaneleko.
(13) Ngesikhathi sokuhlolwa kwamandla wamavalvu wensimbi, thepha umzimba wevalvu nesivalo sevalvu ngebheli yethusi ukuhlola ukuvuza.
(14) Lokha ivalvu nayihlolwako, ngaphandle kwamavalvu wepulagi avumela bona indawo yokuvala ifakwe amafutha, amanye amavalvu awavunyelwa ukuhlola indawo yokuvala ngamafutha.
(15) Ngesikhathi sokuhlolwa kwengcindezi yevalvu, amandla wokugandelela wepuleti engabonakaliko kuvalvu akukafaneli abe makhulu khulu, ukwenzela bona kugwenywe ukuguquguquka kwevalvu begodu kuthinte umphumela wokuhlolwa (nangabe ivalvu yensimbi egandelelweko igandelelwe khulu, izokulimala).
(16) Ngemva kokuthi ukuhlolwa komfutho wevalvu kuqedwe, amanzi abutheleleko emvalwini kufanele asuswe ngesikhathi begodu asulwe ahlanzeke, begodu irekhodi lokuhlolwa kufanele lenziwe.
In I-TWS Valve, malungana nomkhiqizo wethu omkhulu, i-valve ye-butterfly ehlezi ethambileko, kufanele ithwalwe ukuhlolwa kokuqina kwesihlalo esiphezulu. Begodu indawo yokuhlola ngamanzi nofana igesi, begodu amazinga womtjhiso wendawo yokuhlola aphakathi kwama-5°C~40°C.
Begodu ukuhlolwa okulandelako kukuqina kwegobolondo nokusebenza kwevalvu.
Umnqopho wayo kukuthi ukuhlolwa kuzokuqinisekisa ukuqina kokuvuza kwegobolondo okufaka hlangana ukuvala kwendlela yokusebenza malungana nokugandeleleka kwangaphakathi.
Ngesikhathi senqubo yokuhlolwa, kufuze sitjheje bona uketshezi lokuhlolwa lizakuba ngamanzi.
Begodu idiski yevalvu izokuba sebujameni obuvulekileko. Iinhlanganisela zokugcina zevalvu zizokuvalwa begodu yoke imigodi izaliswe ngamanzi wokuhlolwa. Umfutho otjhiwo ngeenkhathi ezi-1.5 ze-PN uzakusetjenziswa emanzini wokuhlola.
