IValve yoxinzelelo lwangasemva
I-UPVC CPVC PPH PVDF ngasemva iValve yoxinzelelo lwePvc yoNcedo loKhuseleko lweValve
Iimpawu zeeMveliso
Ukukhulula uxinzelelo lombhobho ukuqinisekisa ukuzinza koxinzelelo lwenkqubo.
Khusela ukhuseleko lwempompo kunye nokusebenza okuqhelekileyo kwenkqubo.
Isetyenziswe ngokubambisana ne-pulse dampers ukunciphisa umonakalo wehamile yamanzi kwinkqubo, ukuphumeza ukulawulwa kwe-vibration ephezulu; ukunciphisa incopho yokuguquguquka kwesantya sokuhamba, ukukhusela inkqubo yemibhobho kwimpembelelo yokutshintsha koxinzelelo.
I-diaphragm isebenzisa iteknoloji ehlanganisiweyo ye-PTFE+glue, elungele phantse zonke iilwelo ezidliwayo, ezinokutywinwa okuthembekileyo kwaye akukho kuvuza.
Ivalve yokhuseleko isetyenziselwa ntoni?
I-diaphragm, i-spool ngoxinzelelo lwangaphakathi lwasentwasahlobo ngokuchasene nesitulo sevalvu. Xa uxinzelelo kumbhobho wenkqubo ludlula uxinzelelo olusetwe kwangaphambili, i-diaphragm, i-spool iyakhutshwa. Ukuvuza okuphakathi kumbhobho wokubuyisela kunye nesitya. Kwintsimi inokulungelelaniswa nge-screws ngoncedo lwe-gauge ye-pressure gauge kwi-pipeline kwi-0-1.0Mpa uluhlu lwezicwangciso zoxinzelelo, uxinzelelo lokunciphisa ngokuqhelekileyo lubekwe phezulu kunoxinzelelo lwenkqubo ye-0.1-0.2Mpa. Umlawuli wevalve yokhuseleko akavumelekanga ukuba adlule ubuninzi boxinzelelo lwempompo. Ukufakela ngokubanzi ngokusondeleyo ngokusemandleni kwi-outlet yempompo. Akufanele kubekho iivalve phakathi kwempompo kunye nevalve yokhuseleko, ukukhusela ukhuseleko lwempompo kunye nokusebenza ngokuqhelekileyo kwenkqubo.
Ivalve yoxinzelelo lwangasemva isetyenziselwa ntoni?
Ifakwe kumbhobho wokukhupha uxinzelelo olulungileyo lwempompo yokulinganisa okanye ipompo ye-diaphragm. Okuthintela ukwenzeka kwe-siphon phenomenon, ukuphelisa utshintsho lwedosaji olubangelwa ukuguquguquka koxinzelelo kwindawo yedosi, ukwenzela ukuba kuqinisekiswe ukuchaneka kwe-dosage yepompo. Kwintsimi sisusa i-cap yokukhusela kwi-screws yokulungisa, ukujikeleza i-screws yokulungisa, kwaye ulungelelanise uxinzelelo olufunekayo ngoncedo lwe-gauge yoxinzelelo kwipayipi. Iyakwazi ukulungiswa ngokulungelelanisa izikrufu kuluhlu lwe-0-0.6 Mpa ukuseta uxinzelelo lwangasemva. Enokuthi isetyenziswe ngokubambisana ne-pulse damper ukunciphisa umonakalo wehamile yamanzi kwinkqubo. Ukugcina uxinzelelo oluthile oluqhubekayo olusuka kwipompo ukuya kwi-valve yoxinzelelo lwangasemva, kunye nokugcina izinga lokuhamba rhoqo kwenkqubo.
Uthini umahluko phakathi kwevalve yokunciphisa uxinzelelo kunye nevalve yoxinzelelo lwangasemva?
I-valve yoxinzelelo lwangasemva, luhlobo lwesivalo esinjongo yayo iphambili kukukhusela ukusebenza ngokukhuselekileyo kwempompo. Iivalve zoxinzelelo lwangasemva ziqinisekisa ukusebenza ngokukhuselekileyo kwempompo ngokulawula ukuhanjiswa koxinzelelo lokungena kwempompo.
Iivalve zokunciphisa uxinzelelo, okanye iivalve zokulawula ngokuzenzekelayo, zisetyenziselwa ukulawula uxinzelelo lwenkqubo. Iivalve zokunciphisa uxinzelelo zihlala zisetyenziselwa imibhobho kunye neenkqubo ezifuna ukukwazi ukugcina uxinzelelo oluphantsi rhoqo kwizixhobo ezithile apho kukho uthintelo kuxinzelelo oluphezulu.
Ivalve yoxinzelelo lwangasemva isetyenziselwa kakhulu ukukhusela ukusebenza ngokukhuselekileyo kwempompo, luhlobo lwendlela "ezenzekelayo" yokulawula ivalve. ngelixa ivalve yokunciphisa uxinzelelo isetyenziselwa ukulawula uxinzelelo lwenkqubo, kukho "i-manual" kunye ne "automatic" iindlela ezimbini. Iindlela ezimbini. Ukongezelela, i-valve yoxinzelelo oluqhelekileyo lwasemva isetyenziswe kwi-inlet yempompo, ngelixa i-valve yokunciphisa uxinzelelo isetyenziswe ekuphumeni kwenkqubo, ngokukodwa ngenxa yemisebenzi yabo ephambili eyahlukeneyo.
