Kukho iintlobo ezininzi zeevalvu zeebhabhathane, kwaye kukho iindlela ezininzi zokuhlela.
1. Uhlulo ngokwemo yesakhiwo
(1)ivalvu yebhabhathane egxile kwindawo enye(2) ivalvu yebhabhathane ene-eccentric enye; (3) ivalvu ephindwe kabiniivalvu yebhabhathane engaqhelekanga(4) ivalvu yebhabhathane enemilo emithathu
2. Uhlu ngokwezinto zomphezulu wokutywina
(1) Ivalvu yebhabhathane ehlala iqinile
(2) Ivalvu yebhabhathane eqinileyo evalwe ngohlobo lwesinyithi. Isibini sokutywina senziwe ngezinto eziqinileyo zesinyithi ukuya kwizinto eziqinileyo zesinyithi.
3. Uhlu ngokwendlela etywiniweyo
(1) Ivalvu yebhabhathane evalwe ngenkani.
(2) Ivalvu yebhabhathane yokutywina ngoxinzelelo. Uxinzelelo lwetywina lwenziwa yinto yokutywina elastiki esitulweni okanye kwipleyiti.
(3) Ivalvu yebhabhathane evalekileyo ngokuzenzekelayo. Uxinzelelo oluthile lwesitywino lwenziwa ngokuzenzekelayo luxinzelelo oluphakathi.
4. Uhlu ngokwexinzelelo lomsebenzi
(1) Ivalvu yebhabhathane engenanto. Ivalvu yebhabhathane enoxinzelelo olusebenzayo oluphantsi kunomoya oqhelekileyo.
(2) Ivalvu yebhabhathane enoxinzelelo oluphantsi. Ivalvu yebhabhathane enoxinzelelo oluqhelekileyo lwe-PN≤1.6MPa.
(3) Ivalvu yebhabhathane enoxinzelelo oluphakathi. I-PN yoxinzelelo oluqhelekileyo yivalvu yebhabhathane eyi-2.5∽6.4MPa.
(4) Ivalvu yebhabhathane enoxinzelelo oluphezulu. I-PN yoxinzelelo oluqhelekileyo yivalvu yebhabhathane eyi-10.0∽80.OMPa.
(5) Ivalvu yebhabhathane enoxinzelelo oluphezulu kakhulu. Ivalvu yebhabhathane enoxinzelelo oluqhelekileyo lwe-PN <100MPa.
5. Uhlu ngokwendlela yoqhagamshelo
(1)Ivalvu yebhabhathane yeWafer
(2) Ivalvu yebhabhathane yeFlange
(3) Ivalvu yebhabhathane yeLug
(4) Ivalvu yebhabhathane edityanisiweyo
Ivalvu yebhabhathane engqukuva luhlobo lwevalvu evula kwaye ivale ngepleyiti yebhabhathane ejikelezayo ize ivule, ivale kwaye ilungise umjelo wolwelo ngokujikeleza kwesiqu sevalvu. Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwitshaneli ye-cylindrical yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane yediski ijikeleza i-axis, kwaye i-Angle yokujikeleza iphakathi kwe-0 kunye ne-90. Xa ukujikeleza kufikelela kwi-90, ivalvu ivuleke ngokupheleleyo.
Amanqaku aphambili okwakha nokufakela
1) Indawo yokufaka, ukuphakama, ukungenisa kunye nokuthumela ngaphandle kufuneka kuhlangabezane neemfuno zoyilo, kwaye uqhagamshelo kufuneka luqine kwaye luqine.
2) Isiphatho sazo zonke iintlobo zeevalvu ezenziwe ngesandla ezifakwe kumbhobho wokushisa akufuneki sibe phantsi.
3) Ivalvu kufuneka ihlolwe ngaphandle ngaphambi kokufakelwa, kwaye ipleyiti yegama levalvu kufuneka ihlangabezane nemigaqo yomgangatho wesizwe wangoku "uMark General Valve" GB 12220. Kwiivalvu ezinoxinzelelo olusebenzayo olungaphezulu kwe-1.0 MPa kunye nokunqunyulwa kombhobho oyintloko, uvavanyo lwamandla kunye nokusebenza okuqinileyo kufuneka lwenziwe ngaphambi kokufakelwa kwaye kufuneka lusetyenziswe emva kokuba lugqityiwe. Kuvavanyo lwamandla, uxinzelelo lovavanyo luphindwe kayi-1.5 koxinzelelo oluqhelekileyo, kwaye ubude abuyi ngaphantsi kwemizuzu emi-5. Igobolondo levalvu kunye nokupakisha kufuneka kuqinisekiswe ngaphandle kokuvuza. Kuvavanyo lokuqina, uxinzelelo lovavanyo luphindwe kayi-1.1 koxinzelelo oluqhelekileyo; uxinzelelo lovavanyo kufuneka luhlangabezane nomgangatho we-GB 50243 ngexesha lovavanyo, kwaye umphezulu wesitywina sevalvu ufanele kuqinisekiswe.
Ukukhethwa kwemveliso yeengongoma eziphambili
1. Iiparameter eziphambili zolawulo lwevalvu yebhabhathane ziinkcukacha kunye nobukhulu.
2. Ivalvu yebhabhathane yivalvu yomoya yepleyiti enye, isakhiwo sayo silula, kulula ukuyilungisa, ixabiso eliphantsi, kulula ukuyisebenzisa, kodwa ukuchaneka kokulungiswa akukuhle, ifanelekile kuphela kwinkqubo yokungenisa umoya kunye neyomoya ukuze kutshintshelwe okanye kulungiswe kakuhle imeko.
3. Ingasebenza ngesandla, ngombane okanye ngohlobo lweziphu, ingalungiswa kuyo nayiphi na i-engile yoluhlu lwama-90.
4. Ngenxa yepleyiti yevalvu enye ye-axial enye, amandla okuthwala anqongophele, kwimeko yomahluko omkhulu woxinzelelo, izinga lokuhamba okukhulu xa ubomi benkonzo yevalvu bufutshane. Ivalvu inohlobo oluvaliweyo nohlobo oluqhelekileyo, ubushushu kunye nokungabi bubushushu.
5. Ivalvu yebhabhathane yombane inolawulo lweentlobo ezimbini kuphela, i-actuator yombane iyafana nevalvu enamagqabi amaninzi.
