Ukufakwa kwevalvu yebhola

Ivalve yebholaukuhlohla:

1. Kufuneka kuqinisekiswe ukuba umbhobho kunye nokusebenza kwevalvu kucociwe.

2. i actuator yeivalve yebholaukusebenza ngokobungakanani bomqondiso wegalelo ukuqhuba ukujikeleza kwesiqu: ukujikelezisa phambili 1/4 (90 °),ivalve yebholaivaliwe.Iivalve yebholaivulwa xa ujikelezo oluyi-1/4 lujika (90°).

3.Xa utolo olubonisa indlela ye-actuator ihambelana nombhobho, ivalve iyavulwa;Ivalve ivaliwe xa utolo luthe gqolo kumgca.

Ivalve yebholaulondolozo:

Ukuphila ubomi obude benkonzo kunye nexesha elingenalo lokugcinwa kuya kuxhomekeka kwizinto ezininzi: iimeko eziqhelekileyo zokusebenza, ukugcina ubushushu obuhambelanayo / umlinganiselo woxinzelelo, kunye nedatha ye-corrosion efanelekileyo.

Qaphela: xa iivalve yebholaivaliwe, uxinzelelo lolwelo lusekho kumzimba wevalvu

Ngaphambi kokusevisa, susa uxinzelelo lomgca kunye nevalve yendawo kwindawo evulekileyo

Susa umbane okanye umthombo womoya phambi kolungiso

Nqamula i-actuator kwinkxaso phambi kokulungiswa

1. Isitshixo sokupakisha

Ukuba ukupakisha ikholvethi kukuvuza okuncinci, kufuneka utshixe i-stem nut.

Qaphela: Musa ukutshixa, ngokuqhelekileyo tshixa i-1/4 iringi ukuya kwiringi ye-1, ukuvuza kuya kuyeka.

2. Buyisela indawo yokuhlala kunye netywina

A. Susa

Yiyeke ivalve kwindawo evuleke-ngesiqingatha ukuze igungxule ngaphakathi nangaphandle kwevalve ngezixhobo ezinokuba yingozi.

Valaivalve yebhola, susa iibholiti kunye namantongomane kuzo zombini iiflange kwaye ususe ivalve ngokupheleleyo kwimibhobho.

Susa i-drive - i-actuator, i-bracket yokudibanisa, i-anti-loose washer, i-stem nut, i-butterfly shrapnel, i-Gernan, i-disc yokunxiba, ukupakishwa kwesiqu ngokulandelelana.

Susa iibholiti zoqhagamshelo kunye namandongomane, hlukana nesigqubuthelo somzimba, kwaye ususe i-gasket yokugubungela.

Qinisekisa ukuba ibhola ikwindawo "yokucima" ukuyisusa ngokulula emzimbeni kwaye ususe isihlalo.

Tyhila isiqu ngobunono ezantsi kumngxunya osembindini womzimba de ususwe ngokupheleleyo, uze ususe i-O-ring kunye neringi yokupakisha.

Qaphela: Sebenzisa isilumkiso ukuphepha ukukrwela umphezulu wesiqu kunye nokupakisha isivalo sevalve.

B. Hlanganisa kwakhona

Coca kwaye uhlole iindawo eziphantsi kokuhlolwa.Ukutshintshwa kwesihlalo kunye neegaskets zebhonethi kunye nokutywinwa kunye nekhithi yeendawo ezisecaleni kuyacetyiswa kakhulu.

Hlanganisa ngokulandelelana kwe-disassembly.

Umnqamlezo-tshixa iibholithi zeflange ezinetorque ekhankanyiweyo.

Qinisa amandongomane ngetorque echaziweyo.

Emva kokufaka i-actuator, jikelezisa i-valve stem ukuze uqhube i-spool ukujikeleza isignali ehambelanayo yokufaka ukuvula nokuvala ivalve.

Ukuba kunokwenzeka, uvavanyo loxinzelelo lwetywina kunye nevalve yokuvavanya ukusebenza ngokwemigangatho emva kokufakelwa kwemibhobho.
