I-SX-12 Ivalve yokuhambisa i-SX-14 ivalve engundoqo ye-oyile yokungenisa ivalve ephakathi

Uninzi lwabembi baneempompo ezimbini eziphambili, ngoko ke ivalve yoncedo ephambili inezimbini (ekwabizwa ngokuba yivalve ephambili yokhuseleko), ngokulandelelana lawula impompo ephambili, kwaye impompo nganye ilawula iintshukumo ezi-3, ibhakethi kunye nengalo enkulu yokuhamba ngecala elinye. liqela, ingalo ephakathi, ukujikeleza kunye nokungaphandle kokuhamba kwecala liqela, zonke iivalvu ezimbini eziphambili zoncedo (iivalvu zoncedo olulingwayo) zilawula izenzo ezintathu ezichaseneyo.

Kwaye ekugqibeleni banazo iivalvu zabo zokunceda kwisenzo ngasinye, njengengalo ephakamisayo kunye nengalo ethobayo ezineevalvu zabo zokukhulula. I-valve engundoqo yokunceda ilawula ubukhulu becala uxinzelelo lweempompo ezimbini eziphambili, ngoko ke uxinzelelo lwezenzo ezintathu ezilawulwa yimpompo eziphambili ziyafana, ngokweemfuno, ukuba uxinzelelo lwesenzo esisodwa alwanelanga okanye luphezulu kakhulu, ngoko ke uxinzelelo lwesenzo esisodwa alwanelanga okanye lukhulu kakhulu, ngoko ke ivalve yoncedo eyahlukileyo yesenzo inokulungiswa.

Umgaqo wokusebenza kunye nomsebenzi wevalve yokunceda

I-1, i-valve yokunceda i-valve yoxinzelelo rhoqo isiphumo sokuphuphuma koxinzelelo: kwi-quantitative pump throttling regulation system, ipompo yobungakanani inika ukuhamba rhoqo. Xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iya kuncipha. Ngeli xesha, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okugqithisiweyo kubuyele kwi-tank, ukuqinisekisa ukuba i-valve yokunceda i-inlet yoxinzelelo, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhlala (i-valve port ivame ukuvulwa ngokuguquguquka koxinzelelo) .

I-2, ukhuseleko lokhuseleko: Xa inkqubo isebenza ngokuqhelekileyo, i-valve ivaliwe. Kuphela xa umthwalo udlula umda ochaziweyo (uxinzelelo lwenkqubo ludlula uxinzelelo olubekiweyo), ukugqithiswa kuvuliwe ukwenzela ukhuseleko lomthwalo ogqithisiweyo, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kunyuka (ngokuqhelekileyo uxinzelelo olumiselweyo lwevalve yokunceda luyi-10% ukuya kwi-20% phezulu kunoxinzelelo oluphezulu lomsebenzi wenkqubo).

3, njengevalve yokukhulula esetyenziswa njengomlawuli woxinzelelo olude:

I-valve yokulawula i-multistage ephezulu kunye nephantsi isetyenziswe njengevalve yokulandelelana ukuvelisa uxinzelelo lwangasemva (umtya kwi-oyile yokubuyisela isiphaluka).

Ivalve yokulingwa yokunceda inamacandelo amabini: ivalve engundoqo kunye nevalve yokulinga. Iivalve zolingo ziyafana neevalve ezisebenza ngokuthe ngqo, kodwa ngokuqhelekileyo zizivalo zekhowuni (okanye ivelufa yebhola) izitulo ezimilise okwezihlalo. I-valve ephambili inokwahlulwa ibe yisakhiwo esinye esigxininisekileyo, i-concentric structure emibini kunye ne-concentric structure.
