Izinto ezilungileyo zevalve yesango:
(1) Ukuxhathisa ulwelo oluncinci Ngenxa yokuba umjelo ophakathi ophakathi womzimba wevalve yesango uthe tye, i-medium ayitshintshi indlela yokuhamba kwayo xa ihamba ngevalve yesango, ngoko ke ukuxhathisa ulwelo kuncinci.
(2) Itorque yokuvula kunye nokuvala incinci, kwaye ukuvula kunye nokuvala kusindisa abasebenzi.Ngenxa yokuba isalathiso sentshukumo yesango i-perpendicular ukuya kwicala lokuhamba okuphakathi xa ivalve yesango ivuliwe kwaye ivaliwe, ukuvulwa kunye nokuvalwa kwevalve yesango kusindisa umsebenzi ngakumbi xa kuthelekiswa nevalve yokumisa.
(3) Indlela yokuhamba yendlela ephakathi ayithinteli, kwaye i-medium inokuhamba kuyo nayiphi na indlela ukusuka kumacala omabini evalve yesango ngaphandle kokuphazamisa ukuhamba kwaye ngaphandle kokunciphisa uxinzelelo, kwaye injongo yokusetyenziswa inokufezekiswa.Kufanelekile ngakumbi kwimibhobho apho ulwalathiso lokuhamba kwamanzi lunokutshintsha.
(4) Ubude besakhiwo bufutshane ngenxa yokuba isango levalvu yesango libekwe ngokuthe nkqo kumzimba wevalvu, kwaye idiskhi yevalve yesivalo sibekwe ngokuthe tye kumzimba wevalvu, ngoko ke ubude besakhiwo bufutshane kunobo bokumisa. ivalve.
(5) Ngokusebenza kakuhle kokutywina, umphezulu wokutywina awukhukuliseka kancinci xa uvulwe ngokupheleleyo.
(6) Xa ivuleke ngokupheleleyo, ukhukuliseko lomphezulu wokutywina luncinane kunolo lwevalvu yokumisa.
(7) Ubume bomzimba bulula, inkqubo yokuphosa ilungile, kwaye uluhlu lwesicelo lubanzi.
Ukungalungi kwevalve yesango:
(1) Umphezulu wokutywina kulula ukonakalisa amatywina amabini adityaniswe nesitulo sevalve ngexesha lokuvula nokuvalwa, kwaye kukho ukungqubana phakathi kwamatywina amabini, ekulula ukuwonakalisa, kuchaphazela ukusebenza kunye nobomi benkonzo itywina, kwaye kunzima ukuyigcina.
(2) Ixesha lokuvula kunye nokuvala lide, kwaye ukuphakama kukhulu.Ngenxa yokuba i-valve yesango kufuneka ivulwe ngokupheleleyo okanye ivalwe ngokupheleleyo xa ivula kwaye ivala, i-stroke yesango inkulu, kwaye indawo ethile iyadingeka ekuvuleni, kwaye ubukhulu becala buphezulu, kwaye indawo yokufakela inkulu.
(3) Iivalvu zesango ezinesakhiwo esintsonkothileyo ngokuqhelekileyo zinemigangatho emibini yokutywina, eyandisa ukusetyenzwa, ukugaya kunye nokugcinwa.Kukho iindawo ezinzima ngakumbi, ukuveliswa kunye nokugcinwa kunzima kakhulu, kwaye iindleko ziphezulu kuneevalvu zeglowubhu.
Idayamitha yevalve yesango iyacutheka:
Ukuba i-diameter yepaseji kumzimba wevalvu yahlukile (ihlala i-diameter kwisitulo sevalve incinci kune-diameter yoqhagamshelo lwe-flange), ibizwa ngokuba yi-diameter shrinkage.
I-shrinkage ye-diameter inokunciphisa ubukhulu beengxenye, ukunciphisa amandla afunekayo ekuvuleni nasekuvaleni, kunye nokwandisa uluhlu lwezicelo zamacandelo.Kodwa emva kokuba i-diameter iyancipha.Ilahleko yokumelana nolwelo iyanda.
Ngaphantsi kweemeko ezithile zokusebenza kumasebe athile (njengemibhobho yeoli kwicandelo lepetroleum), iivalve ezinobubanzi obuncitshisiweyo azivumelekanga.Ngakolunye uhlangothi, kukunciphisa ukulahlekelwa kokuchasana kombhobho, kwaye ngakolunye uhlangothi, kukuphepha imiqobo yokucocwa komatshini wombhobho emva kokunciphisa ububanzi.
Ufakelo kunye nokugcinwa kwevalve yesango kufuneka kuthathelwe ingqalelo le miba ilandelayo:
1. Amavili esandla, izibambo kunye neendlela zokuhambisa azivumelekanga ukuba zisetyenziswe ekuphakamiseni, kwaye ukungqubana kunqatshelwe ngokungqongqo.
2. Ivalve yesango eliphindwe kabini kufuneka ifakwe ngokuthe nkqo (oko kukuthi, isiqu sevalve sikwindawo ethe nkqo kwaye ivili lesandla liphezulu).
3. I-valve yesango ene-valve ye-bypass kufuneka ivulwe ngaphambi kokuvula (ukulinganisela ukuhlukana koxinzelelo phakathi kokungena kunye nokuphuma kunye nokunciphisa amandla okuvula).
4. Ivalve yesango enendlela yokuhambisa kufuneka ifakwe ngokwencwadi yemveliso.
5. Ukuba ivalve ivulwa kwaye ivalwe rhoqo, gcoba ubuncinane kanye ngenyanga.
I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
