Ivalve yolawulo eqhelekileyo ibandakanya umzimba wevalve, amalungu evalve yangaphakathi, i-actuator ebonelela ngedrive yokusebenza kwevalvu, kunye nezixhobo ezahlukeneyo zevalvu. Izixhobo zeValve ziquka ii-positioners, ii-transducers, izilawuli zokubonelela ngoxinzelelo, i-solenoid valves, i-dampers kunye nokutshintsha umda.

1. Ukukhethwa kunye nokusetyenziswa kweevalve zokulawula
Ukhetho oluchanekileyo lweevalvu zokulawula kunye nokuba ufezekise iimfuno zokulawula iimeko ezichaziweyo zesitshixo, kodwa nokuqinisekisa ukhuseleko lwenkqubo. Ukuze kuhlangatyezwane neemfuno zeemeko ezikhankanyiweyo, ukhetho lweevalvu zokulawula kufuneka luthathele ingqalelo uhlobo lomzimba wevalve, ulwakhiwo kunye nezinto zamalungu evalve, uhlobo lwe-actuator kunye nokhuseleko kunye nezinye izinto. uhlobo lwevalve yolawulo olukhethiweyo ludibaniso olufanelekileyo.

2. Imiba yolawulo lwevalvu iya kuqwalaselwa
Ukukhetha i-valve yokulawula efanelekileyo kwiimeko, kufuneka uqwalasele ngokubanzi impembelelo yokukhethwa kwe-valve yokulawula iimeko ezahlukeneyo zokusebenza. Olona lwazi lubalulekileyo lubandakanya ukulawulwa kohlobo lolwelo, ubushushu be-fluid, i-viscosity ye-fluid, i-gravity ethile ye-fluid, ubukhulu kunye nobuncinci bomthamo wokuhamba, ubuninzi kunye noxinzelelo oluncinci lwe-inlet ye-valve, ubuninzi kunye noxinzelelo oluncinci lwe-valve outlet, uxinzelelo. ukuhla phantsi kweemeko zokuhamba eziqhelekileyo, inani labantu kunye nomgangatho wombhobho wokuphuma kunye nobukhulu bodonga.

3. Inkqubo yokukhetha ivalvu
Indlela yokukhetha i-valve yokulawula efanelekileyo ukuhlangabezana neemfuno zokusetyenziswa kweemeko, inkqubo yokukhetha i-valve yokulawula ubuncinane idinga ukuqwalasela le nkqubo ilandelayo. Misela iimeko zokusebenza: kubandakanywa inani le-valve kunye nokuphuma koxinzelelo oluphezulu lokwahlukana, ubuninzi, ubuncinci kunye neemeko eziqhelekileyo zokusebenza zesantya sokuhamba, ukushisa kwamanzi kunye nengxolo evumelekileyo. Bala i-C-value efunekayo, kwaye unqume umgangatho wengxolo, i-cavitation kunye nokudanyaza ngokubala i-℃-value). Ukukhethwa kohlobo lwangaphakathi lwe-valve: Ukuba ixabiso lengxolo elibalwayo likhulu kunomda ovunyelwe ngummandla womsebenzi, ngoko ukukhethwa kwe-valve yokunciphisa ingxolo kufuneka kuthathelwe ingqalelo. Ukuba i-cavitation ebalwayo okanye ixabiso le-flash ye-valve kumsebenzi ochaziweyo phantsi kokusetyenziswa kwexesha elide lempembelelo enkulu, kufuneka ithathelwe ingqalelo kwiimeko ezichaziweyo ze-anti-cavitation kunye ne-anti-flash valve components.
