Iivalvu eziboniswe kumfanekiso azixhathisi kakhuluiivalvu zokujonga ezithambekileyo ngesando sobunzimayenziwe yiJinbin Valve, enobukhulu obuqala kwi-DN250 ukuya kwi-DN700. Umzimba wevalvu wenziwe ngentsimbi yekhabhoni ye-WCB, ixhotyiswe ngee-counterweights kunye nee-hydraulic cylinders, kwaye ilinganiswe ngokweengcinezelo zokusebenza ze-PN16, PN20 kunye ne-PN25.

Le valve yokuhlola ibhabhathane evala kancinci yohlobo lwe-counterweight kunye ne-hydraulic cylinder isebenzisa isakhiwo sokuvala nokuvula esinezigaba ezibini. Xa ipompo yamanzi isebenza, uxinzelelo oluphakathi lutyhala idiski yebhabhathane ivuleke; i-counterweight iphakamisa kunye nediski ukuze ilinganise ubunzima beplate yebhabhathane, inciphisa kakhulu ukumelana nokuhamba kwamanzi. Okwangoku, i-medium ingena kwi-hydraulic cylinder ukuze igcine uxinzelelo. Ngexesha lokuvalwa kwepompo, phantsi kwamandla adibeneyo e-self-weight, uxinzelelo lwe-counterweight kunye noxinzelelo lwe-reverse flow, idiski yebhabhathane ivala ngokukhawuleza i-80% ~ 90% yendlela yokuhamba ukuze ivale uninzi lokuhamba emva. I-stroke eseleyo ye-10% ~ 20% ivalwa kancinci nge-hydraulic cylinder damping. I-valve yenaliti ivumela ukulungiswa ngokuchanekileyo kwexesha lokuvala kancinci, elisusa amandla okuchaphazela okuhamba emva inyathelo ngenyathelo kwaye ngokusisiseko licinezela amaza okutshayiswa kwe-hammer water hammer.

Iingenelo zeSicelo esiPhambili

1. Susa isando samanzi kwaye ukhusele izixhobo

Ukuvalwa okucwangcisiweyo kunciphisa amandla ehamile yamanzi enoxinzelelo oluphezulu eveliswa xa ipompo ivaliwe, kuthintela ukuqhekeka kwepayipi kunye nomonakalo wokuguqulwa kweshafti yepompo, kwaye kunciphisa kakhulu iindleko zokugcinwa kwepayipi.

2. Ukumelana nokuhamba kwamanzi okuphantsi kakhulu ukonga amandla

I-counterweight ilinganisa ubunzima be-butterfly plate ukuze ivuleke ngokupheleleyo ngaphandle kokuphazamiseka. Ukulahleka kwentloko yayo kungaphantsi ngama-40% kunee-valve zokujonga i-swing eziqhelekileyo, nto leyo enika amandla exesha elide kunye nokonga iindleko.

3. Ukusebenza kokutywina okuhlala ixesha elide nokuthembekileyo

Inesakhiwo sokutywina idiski yebhabhathane enemibala emibini ukuze ivalwe kakuhle. Umzimba wevalvu ugqunywe ngepeyinti ye-epoxy anti-corrosion, efanelekileyo kwiindawo ezininzi eziquka amanzi acocekileyo, amanzi amdaka kunye namanzi ajikelezayo.

4. Uhlengahlengiso oluguquguqukayo olunokusetyenziswa ngokubanzi

Inkqubo yokudambisa amanzi e-hydraulic ezimeleyo ivumela ukulungiswa kakuhle kwexesha lokuvala elicothayo xa kuyimfuneko. Isebenza ngcono kuneevalvu zokujonga ezithuleyo ezifakwe entwasahlobo ngomda omkhulu kwizikhululo zokumpompa ezinobubanzi obukhulu (DN300 nangaphezulu).

Iivalvu zokujonga eziqhelekileyo zivaleka ngokupheleleyo ngoko nangoko, nto leyo ebangela ukuba ihamile yamanzi ibe nzima. Ukuchaphazeleka rhoqo kunciphisa ubomi benkonzo yeempompo zamanzi, imibhobho kunye neeflanges. Iintlobo ezifakwe entwasahlobo zisebenza kuphela kwiibhothi ezincinci, ezingenamandla okutyhala kunye nokucudisa ngokwaneleyo kwiidayamitha ezinkulu.

Yenzelwe ngokukodwa iindawo zokukhupha iipompo, le valve idibanisa imisebenzi emithathu: ukungabuyisi, ucinezelo lwesando samanzi kunye nokumelana nokuhamba kwamanzi okuphantsi. Ithatha indawo yokudibanisa ivalvu yokujonga eqhelekileyo kunye nesixhobo se-buffer, inciphisa ukufakwa kwemibhobho. Kwiinkqubo zokuhamba kwamanzi amakhulu ezifana nokunikezelwa kwamanzi kamasipala, amanzi ajikelezayo kwisikhululo samandla, ukunikezelwa kwamanzi kunye nokukhupha amanzi amdaka ngamakhemikhali, kunye nezitishi zepompo zamanzi amdaka, ikhusela ngokuzinzileyo ukhuseleko lokusebenza kwemibhobho, yandisa ubomi benkonzo yezixhobo zizonke, kwaye inika ukusebenza okuphezulu kweendleko ekusebenzeni nasekugcinweni okupheleleyo.
