Kukho iintlobo ezininzi zeevalvu zebhabhathane, kwaye zininzi iindlela zokuhlela.
1. Ukuhlelwa ngokwefom yesakhiwo
(1)ivalve yebhabhathane egxile; (2) ivelufa yebhabhathane ene-eccentric; (3) kabini-Ivalve yebhabhathane eccentric; (4) ivelufa yebhabhathane eneeccentric ezintathu
2. Ukuhlelwa ngokwezinto ezingaphezulu zokutywinwa
(1) Ivalve yebhabhathane eyomelelayo
(2) Ivalve yebhabhathane etywiniweyo yohlobo lwesinyithi. Isibini sokutywina senziwe ngezinto ezilukhuni zentsimbi ukuya kwizinto eziqinileyo zetsimbi.
3. Ukuhlelwa ngokwefomu etywiniweyo
(1) Ivalve yebhabhathane etywiniweyo enyanzelekileyo.
(2) Ivalve yebhabhathane yokutywina ngoxinzelelo. Uxinzelelo lwetywina lwenziwa yinto yokutywinwa kwe-elastic kwisihlalo okanye kwipleyiti.
(3) Ivalve yebhabhathane ezivalwayo etywiniweyo. Uxinzelelo oluthile lwetywina lwenziwa ngokuzenzekelayo luxinzelelo oluphakathi.
4. Ukuhlelwa ngoxinzelelo lomsebenzi
(1) Ivalve yebhabhathane efunxayo. Ivalve yebhabhathane enoxinzelelo lokusebenza olusezantsi kunomoya oqhelekileyo.
(2) Ivalve yebhabhathane enoxinzelelo oluphantsi. Ivalve yebhabhathane enoxinzelelo lwegama lwe-PN≤1.6MPa.
(3) Ivalve yebhabhathane enoxinzelelo oluphakathi. Uxinzelelo lwegama lwe-PN yivalve yebhabhathane eyi-2.5∽6.4MPa.
(4) Ivalve yebhabhathane enoxinzelelo oluphezulu. I-PN yoxinzelelo lwegama yivalve yebhabhathane ye-10.0∽80.OMpa.
(5) Ivalve yebhabhathane enoxinzelelo oluphezulu. Ivalve yebhabhathane enoxinzelelo lwegama PN <100MPa.
5. Ukuhlelwa ngendlela yoqhagamshelwano
(1)Ivalve yebhabhathane yeWafer
(2) Ivalve yebhabhathane eneflethi
(3) Lug butterfly valve
(4) Ivalve yebhabhathane edityanisiweyo
Ivalve yeButterfly eNxibeleleyo luhlobo lwesivalo esivula sivale ngepleyiti yebhabhathane ejikelezayo kwaye ivule, ivale kwaye ilungelelanise umjelo wolwelo ngokujikeleza kwesiqu sevalve. Ipleyiti yebhabhathane yevalve yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwi-cylindrical channel ye-butterfly valve body, i-disc butterfly plate ijikeleza i-axis, kwaye i-Angle yokujikeleza iphakathi kwe-0 kunye ne-90. Xa ukujikeleza kufinyelela kwi-90, i-valve ivuleke ngokupheleleyo.
Amanqaku aphambili okwakha kunye nofakelo
I-1) Indawo yofakelo, ukuphakama, ukungenisa kunye nokuthunyelwa ngaphandle kwesikhokelo kufuneka kuhlangabezane neemfuno zoyilo, kwaye uqhagamshelo kufuneka luqine kwaye luqine.
2) Isibambo sazo zonke iintlobo zeevalvu ezifakwe kwi-thermal insulation pipe ayiyi kuba phantsi.
3) Ivalve kufuneka ihlolwe ngaphandle phambi kokufakwa, kwaye i-nameplate yevalve iya kuhlangabezana nemimiselo yomgangatho welizwe langoku "i-General Valve Mark" GB 12220. Kwiivalve ezinoxinzelelo olusebenzayo olungaphezu kwe-1.0 MPa kunye nokunqunyulwa kwinqanaba eliphambili. umbhobho, amandla kunye novavanyo lokusebenza oluluqilima luya kuqhutywa phambi kofakelo kwaye luya kusetyenziswa emva kokufaneleka. Kuvavanyo lwamandla, uxinzelelo lovavanyo luyi-1.5 ngamaxesha oxinzelelo lwegama, kwaye ubude abukho ngaphantsi kwe-5min. Igobolondo yevalve kunye nokupakishwa kufuneka ifaneleke ngaphandle kokuvuza. Uvavanyo lokuqina, uxinzelelo lovavanyo luyi-1.1 amaxesha oxinzelelo oluncinci; Uxinzelelo lovavanyo luya kuhlangabezana nomgangatho we-GB 50243 ngexesha lovavanyo, kwaye i-valve seal surface ifanelekile.
Ukukhethwa kwemveliso yamanqaku aphambili
1. Iiparamitha eziphambili zolawulo lwevalve yebhabhathane zizinto ezichaziweyo kunye nemilinganiselo.
2. I-valve ye-butterfly yi-valve yomoya yepleyiti enye, isakhiwo sayo esilula, ukusetyenzwa ngokufanelekileyo, iindleko eziphantsi, ukusebenza okulula, kodwa ukuchaneka kokulungelelaniswa kumbi, ifanelekile kuphela kwi-ventilation kunye ne-air conditioning system yokutshintsha okanye ukulungiswa kwe-coarse kweso sihlandlo.
3. Ingaba yi-manual, umbane okanye uhlobo lwe-zipper, lunokulungiswa kuyo nayiphi na i-Angle ye-90.
4. Ngenxa ye-axial single valve plate, amandla okuthwala alinganiselwe, kwimeko yokwahlukana okukhulu koxinzelelo, isantya esikhulu sokuhamba xa ubomi benkonzo yevalve bufutshane. I-valve inohlobo oluvaliweyo kunye nohlobo oluqhelekileyo, ukugquma kunye nokungabikho kwe-insulation.
5. Ivalve yebhabhathane yombane inolawulo lweentlobo ezimbini kuphela, i-actuator yombane iyafana nevalve enamagqabi amaninzi.
