Isimiso sokusebenza se-valve yesango laseShayina sichazwa ngokuningiliziwe: ukuphakanyiswa kwesango kuqaphela ukuvulwa nokuvalwa kwe-valve ye-fluid yaseShayina yesango, njengengxenye ebalulekile yesistimu yokulawula uketshezi, isimiso sayo sokusebenza nokusebenza kuthinta ngokuqondile ukusebenza kahle nokuphepha. lwalo lonke uhlelo. Lesi sihloko sizohlaziya isimiso sokusebenza sama-valve wesango laseShayina ngokuningiliziwe ngombono wochwepheshe. Okokuqala, isakhiwo esiyisisekelo se-valve yesango lase-China i-valve yesango laseShayina ikakhulukazi yakhiwa umzimba we-valve, ikhava ye-valve, ipuleti lesango, isiqu se-valve, indandatho yokubeka uphawu, ukupakisha nezinye izingxenye. Phakathi kwabo, umzimba we-valve uyingxenye eyinhloko ye-valve, esetshenziselwa ukuxhuma ipayipi; Isembozo se-valve sisetshenziswa kakhulu ukuvala umzimba we-valve; Ipuleti lesango liyingxenye eyinhloko yokushintsha ye-valve, engavula futhi ivale isiteshi samanzi ngokuphakamisa nokwehlisa. Isiqu se-valve sisetshenziselwa ukushayela ukuphakama kwesango; Indandatho yokuvala nokupakisha kusetshenziswa kakhulu ukuqinisekisa ukusebenza kokuvala kwe-valve. Okwesibili, isimiso sokusebenza se-valve yesango lase-China 1. Inqubo yokuvula: Lapho isiqu siphakanyiselwa phezulu, isango liphakama nalo, ukuze isiteshi esiphakathi kwesihlalo se-valve nomzimba we-valve sivuleke kancane kancane, futhi uketshezi lukwazi ukugeleza kulesi siteshi. . Le nqubo ifinyelelwa ngokushayela inqama phezulu naphansi ngesiqu se-valve. 2. Inqubo yokuvala: Lapho isiqu sihamba phansi, isango liyawa, ukuze umzila phakathi kwesihlalo se-valve nomzimba we-valve uvalwe kancane kancane, futhi uketshezi alukwazi ukugeleza kulo mzila. Le nqubo iphinde izuzwe ngesiqu se-valve ukushayela inqama phezulu naphansi. Okwesithathu, izici ze-valve yesango lase-China 1. Isakhiwo esilula: Isakhiwo se-valve yesango lase-China silula, ikakhulukazi sakhiwe izingxenye eziningana, kulula ukwenza nokugcina. 2. Ukusebenza kahle kokuvala: indawo yokuvala yama-valve esango laseShayina ivamise ukuba isicaba noma i-annular, engafinyelela umphumela omuhle wokuvala. 3. Ukumelana noketshezi oluncane: Ngenxa yokuthi ukuphakanyiswa kwesango kungabona ukuvulwa nokuvalwa kwesiteshi samanzi, ukumelana noketshezi lwe-valve yesango laseShayina kuncane kakhulu. 4. Amandla amakhulu okusebenza: Ngenxa yokuthi ukuphakanyiswa kwesango kudinga ukuqhutshwa isiqu se-valve, amandla okusebenza e-valve yesango laseShayina makhulu ngokuqhathaniswa. I-5, ayifanele ukulawula ukugeleza: ngenxa yokuthi ukuphakanyiswa kwesango kungabona kuphela ukuvulwa nokuvalwa kwesiteshi samanzi, ubukhulu besiteshi samanzi abukwazi ukulungiswa, ngakho-ke, i-valve yesango laseShayina ayifanele ukulawula ukugeleza. Okwesine, ukusetshenziswa kwe-valve yesango lase-China Ngenxa yokuthi i-valve yesango laseShayina inezici zesakhiwo esilula, ukusebenza kahle kokuvala uphawu, ukumelana noketshezi oluphansi, njll., isetshenziswa kabanzi ohlelweni lokulawula uketshezi lwe-petroleum, imboni yamakhemikhali, i-metallurgy, amandla kagesi. nezinye izimboni. Ikakhulukazi esidingweni sezikhathi zokuvula nokuvala njalo, njengokusika, ukusika nokunye ukusebenza, izinzuzo zokusebenza kwamavalvu esango laseChina zisobala kakhulu. Kafushane, i-valve yesango laseShayina iwuhlobo lwe-valve eqaphela ukuvulwa nokuvalwa kwesiteshi samanzi ngesango eliphakamisayo. Isakhiwo sayo esilula, ukusebenza kahle kokuvala uphawu kanye nokumelana noketshezi oluphansi kwenza isetshenziswe kabanzi ezinhlelweni ezihlukahlukene zokulawula uketshezi. Kodwa-ke, ngenxa yamandla ayo amakhulu okusebenza, awakulungele ukulawula ukugeleza nokunye ukushiyeka, futhi ikhawulela ukusetshenziswa kwayo kwezinye izikhathi ezikhethekile.
