Masithi kukho umbhobho wokuhambisa amanzi onesigqubuthelo.Amanzi atofwa ukusuka ezantsi kombhobho aze akhutshelwe kumlomo wombhobho.Isigqubuthelo sombhobho wokuphuma kwamanzi silingana nelungu lokuvala levalve yokumisa.Ukuba uphakamisela isigqubuthelo sombhobho phezulu ngesandla sakho, amanzi aya kukhutshwa.Gubungela i-tube cap ngesandla sakho, kwaye amanzi aya kuyeka ukuqubha, elilingana nomgaqo wevalve yokumisa.
Iimpawu zevalve yeglowubhu:
Isakhiwo esilula, ukuqina okuphezulu, ukuveliswa kunye nokugcinwa ngokufanelekileyo, ukuxhathisa okukhulu kwamanzi, kunokulawula ukuhamba;xa ifakwe, iphantsi kwaye iphezulu ngaphandle, iqondise;ngokukodwa isetyenziswe kunikezelo lwamanzi ashushu nabandayo kunye nemibhobho yomphunga woxinzelelo oluphezulu, ayifanelekanga Ukususa amasuntswana kunye ne-solvents viscous kakhulu.
Umgaqo wokusebenza kwevalvu yebhola:
Xa ivalve yebhola ijikeleza i-90 degrees, iindawo ezingqukuva kufuneka zivele zonke kwindawo yokungena kunye ne-outlet, ngaloo ndlela ivale ivalve kwaye imise ukuhamba kwe-solvent.Xa i-valve yebhola ijikeleza i-degrees ezingama-90, ukuvulwa kwebhola kufuneka kubonakale kuzo zombini i-inlet kunye ne-intersection, evumela ukuba iqubhe phantse akukho kumelana nokuhamba.
Iimpawu zevalve yebhola:
Iivalvu zebhola zikulungele kakhulu, zikhawuleza kwaye zisindisa umsebenzi ukuba zisetyenziswe.Ngokuqhelekileyo, kufuneka ujike kuphela isibambo sevalve ngama-90 degrees.Ngaphezu koko, iivalvu zebhola zingasetyenziswa kulwelo olungacocekanga kakhulu (eziqulathe amasuntswana aqinileyo) kuba undoqo wevalve omile okwebhola utshintsha ulwelo xa uvula naxa uvala.yintshukumo yokusika.
Umgaqo wokusebenza kwevalvu yesango:
Ivalve yesango, ekwabizwa ngokuba ivelufa yesango, yivalve esetyenziswa ngokuqhelekileyo.Umgaqo wayo wokuvala wokuvala kukuba indawo yokutywinwa kwesango kunye nesihlalo sokutywinwa kwesihlalo sevalve igudileyo kakhulu, ithe tyaba kwaye iyahambelana, kwaye iyahambelana ukuvala ukuhamba kolwelo oluphakathi, kunye nokuphucula ukusebenza kokutywinwa ngoncedo lwentwasahlobo okanye imodeli ebonakalayo. yeplate yesango.isiphumo sokwenyani.Ivalve yesango ikakhulu idlala indima yokunqanda ukuhamba kolwelo kumbhobho.
Iimpawu zevalve yesango:
Ukusebenza kokutywinwa kubhetele kunoko kwevalve yokumisa, ukuxhathisa ukukhuhlana kwamanzi kuncinci, ukuvula kunye nokuvala akunzima kakhulu, indawo yokutywina iyancipha ngaphantsi kwe-solvent xa ivuleke ngokupheleleyo, kwaye ayikhawulelwanga ngumkhombandlela wokuhamba kwezinto.Inezalathiso zokuqukuqela ezimbini, ubude obuncinane besakhiwo, kunye nemimandla ebanzi yesicelo.Ubungakanani buphezulu, inani elithile lendawo lifunekayo ekusebenzeni, kwaye ixesha lokuvula kunye nokuvala ixesha elide.Umphezulu wokutywina ukhukuliswa ngokulula kwaye ukrwele ngexesha lokuvula nokuvala.Ezi zibini zokutywina zibangela iingxaki kwimveliso, ukusetyenzwa nokulondolozwa.
Isishwankathelo somahluko phakathi kweevalvu zeglowubhu, iivalve zebhola kunye neevalvu zesango:
Iivalvu zebhola kunye neevalvu zesango zihlala zisetyenziselwa ukulawula ukuvala / ukuvala kunye nokusika ulwelo, kodwa azinakusetyenziswa ngokuqhelekileyo ukulungisa ukuhamba.Ukongeza ekulawuleni ukuvala / ukuvala kunye nokusika ulwelo, iivalvu zokumisa zingasetyenziselwa ukulungisa ukuhamba.Xa kufuneka ulungelelanise izinga lokuhamba, kukulungele ngakumbi ukusebenzisa i-valve yokumisa emva komitha.Ukulawulwa kokutshintshwa kunye nokuhamba-ukusika izicelo, iivalve zesango zisetyenziselwa ukuqwalaselwa kwezoqoqosho.Iivalvu zesango zitshiphu kakhulu.Okanye sebenzisa iivalvu zesango kububanzi obukhulu, ioyile enoxinzelelo oluphantsi, umphunga kunye nemibhobho yamanzi.Ukuqwalasela ukuqina, iivalve zebhola zisetyenziswa.Iivalve zebhola zingasetyenziselwa kwiimeko zokusebenza ezinemigangatho ephezulu yokuvuza, zifanelekile ukuqala ngokukhawuleza kunye nokuvala, kwaye zibe nokusebenza okungcono kokhuseleko kunye nobomi obude kuneevalve zesango.
