Zeziphi iingongoma eziphambili zokukhetha i-valves

UkukhethaJonga i-valvevesIfuna ukuqwalaselwa ngokubanzi kwezinto ezininzi ukuqinisekisa ukusebenza ngokuzinzileyo nangokuthembekileyo phantsi kweemeko ezithile zomsebenzi, kunye nokuthintelwa okusebenzayo kwendawo yokuHlangani kweNdawo yokuHlanganisiweyo. Oku kulandelayo ngamanqaku aphambili okhetho:

Ngokwemigqaliselo ephakathi, uhlobo lwendawo kufuneka luchazwe ngokucacileyo, kwaye ujonga iVOVE ilungele iimpawu zokuhamba ngegesi kufuneka ikhethwe ukuba imibhobho yegesi, ezinje ngeeValves; Imidiya yolwelo inokukhethwa njengohlobo lokuphakamisa phantsi kweemeko ezifanelekileyo zomsebenzi; Inkqubo ye-Steam kufuneka ithathele ingqalelo ukunganyamezeli kwakhe iqondo lobushushu i-steam kunye nendlela yokukhuthaza, kunye nohlobo lwe-diaphragm ngamanye amaxesha lubaluleke ngakumbi. Ukuba i-Medium iguqukile, njenge-Acid okanye isisombululo seAlkali, jonga i-valves eyenziwe ngezinto zokungavisisani. I-valves disves zemithombo yeendaba eyomeleleyo ye-acid ingenziwa nge-polytetrafliothylene, kunye nentsimbi engenasitali kufuneka zikhethwe kwityuwa enamanzi olwandle afana namanzi olwandle afana namanzi olwandle afana namanzi olwandle afana namanzi olwandle. I-viscosity ephezulu ichaphazela ukuguquguquka kweVenkile yokuHlola nokuvalwa. Ngotywala onophawu oluphezulu, ukunqanda ukukhetha uhlobo lokuphakanyiswa ngokuchasene nokuphezulu, kwaye uqwalasele uhlobo lokujikeleza okanye lwebhabhathane. Kwimithombo yeendaba enamasuntswana aqinileyo, jonga i-valves ngokuchasene nokunxiba okuhle kufuneka ikhethwe. I-valves disves kunye nezihlalo zemibhobho njengokuthintela i-drainage yam inokwenziwa ngee-alloys ezinzima, okanye iivalves ezikhethekileyo ezizezisiweyo kufuneka zikhethwe.

Ngokuphathelele kwiiparamitha zokusebenza, khetha AJonga i-valveNgoxinzelelo olufanelekileyo (PN) ngokusekwe kuxinzelelo lokusebenza kwenkqubo yepayipi. Uxinzelelo oluthile kufuneka lube ngaphezulu kwelona xinzelelo lomsebenzi kwaye ushiye umda wokhuseleko. Ukujonga iqondo lokusebenza eliphakathi le-Medium, qinisekisa ukuba ivalve yokutshekisha igubungela uluhlu lobushushu olusebenzayo, kwaye izixhobo ezahlukeneyo zinemiqondo esebenzayo. Khetha ivalve yokutshekisha ene-diameter efanelekileyo (i-DN) esekwe kwixabiso lokuhamba kwenkqubo yombhobho, ekufuneka idibanise ububanzi bombhobho. Ubungakanani bunokukhethwa ngokubhekisa kwi-curve yendawo yokuhambahamba.

Kwiimfuno zokufakelwa, iintlobo ezahlukeneyo zeevalves zokujonga zineemfuno ezahlukeneyo zokufaka. Uhlobo lokuphakamisa lufakwe kwimibhobho ethe tyaba, uhlobo lwe-swing aluthintelwanga, kwaye uhlobo lwebhabhathane lufakwe kwimibhobho ethe nkqo. Indlela yokuhamba yendlela ephakathi kufuneka ivele ezantsi ukuya phezulu. Isikhokelo sokufakwa kufuneka sihambelane nolwalathiso lomzimba wevali. Ukhetho kufuneka luqwalasele indawo yokufaka indawo kwaye ukhethe ivalve yokutshekisha kunye nesakhiwo secandelo kunye nobungakanani obufanelekileyo.

Ngokweemfuno zomsebenzi, ii-valves kufuneka zikhethwe ngokweemfuno zokutywinwa kwenkqubo. Kwiinkqubo ezineemfuno zokuvuza ezingqongqo, isakhiwo setywina esithambileyo sokujonga i-valves kunye nendlela elungileyo yokutywina kufuneka ikhethwe. Iinkqubo ezinomdla kuguquko, khetha i-valves yokutshekisha kunye nemibutho yoxinzelelo. Iinkqubo zexesha elide zokusebenza kufuneka ziqwalasele ubomi benkonzoJonga i-valveveskwaye ukhethe izixhobo ezinokuthenjwa kwaye ziphezulu.
