Ivalve yokulawula isihlalo esinye sepneumatic isebenzisa umoya ocinezelweyo njengomthombo wamandla, thatha isilinda njenge actuator, kwaye ngoncedo lwendawo yokubeka ivalve yombane, ivalve yesolenoid yokuguqula, ivalve yokugada kunye nezinye izixhobo zokuqhuba ivalve, ukuphumeza -i-off or proportional regulation Fumana isibonakaliso solawulo lwenkqubo yokulawula i-industrial automation ukulungelelanisa ukuhamba, uxinzelelo, ukushisa kunye nezinye iiparameters zenkqubo.Ivalve yokulawula umoya ibonakaliswe ngolawulo olulula, ukuphendula ngokukhawuleza, kwaye ngokuyimfuneko ikhuselekile, akukho manyathelo ongezelelweyo obungqina bokudubula.

Ivalve yokulawula isihlalo somoya esincinci, ukukhanya, ukusebenza okuphezulu, umthamo omkhulu, ihambelana nemigangatho ye-IEC yesizukulwana esitsha seemveliso zevalvu yolawulo jikelele.Ilungele ulwelo oluphakathi ngokubanzi kunye neemeko zenkqubo yenkqubo yemveliso.Imodeli eluncedo yenziwe nge-pneumatic multi-spring film actuator kunye ne-low flow resistance resistance single-seat valve.I-actuator entsha ineenzuzo zeqondo eliphezulu, ubunzima obulula, ukufakela okulula kunye nokulinganisa, ukwakheka kwe-compact, i-flow flow passage kunye ne-coefficient enkulu yokuhamba.

I-pneumatic single seat control valve i-stable operation, eneempawu ezithembekileyo zesenzo, ukuvuza kwesihlalo esincinci, iimpawu ezichanekileyo zokuhamba, uluhlu olubanzi oluhlengahlengiswayo njalo njalo.Izibonelelo zayo ezizodwa kuluhlu olubanzi lwabasebenzisi ukufikelela kwisiphumo solawulo oluphezulu.

I-6-Point Routine Repair of the Pneumatic Single Control Valve:

1. Jonga udonga lwangaphakathi lomzimba: Kwimeko yoxinzelelo oluphezulu kunye ne-corrosive medium, udonga lwangaphakathi lwevalve kunye ne-diaphragm yevalve ye-diaphragm zihlala zichaphazeleka kwaye zonakaliswe ngumbindi.

2. Jonga isihlalo: Ngenxa yomsebenzi wokungeniswa kwemidiya, isihlalo esisisigxina kunye nomphezulu wangaphakathi we-screw corrosion kwaye kulula ukwenza isihlalo sokuphumla.

3. Jonga undoqo wevalve: Undoqo wevalve yenye yeendawo ezishukumayo zevalve yolawulo, ukhukuliseko oluphakathi nendawo lunobuzaza ngakumbi, ukuhlolwa nokulungiswa ukujonga ngononophelo ukuba ngaba iinxalenye zevalve core corrod.I-spool eyonakele kakhulu kufuneka itshintshwe;jonga ukupakisha: Khangela ukupakisha intambo ye-asbestos yomile, ukuba ukusetyenziswa kwe-polytetrafluoroethylene ukupakisha, kufuneka ubeke ingqalelo ukujonga ukuba ukuguga kunye nomphezulu wayo wokulinganisa wonakalisiwe.

4. Khangela ukuba ifilimu yerabha kwi-actuator indala kwaye iqhekekile.

Amanqaku ama-6 okufuneka aqwalaselwe ekuSetyenzisweni kweValve yesitulo esinye esineSitulo somoya:

1. Kufuneka ifakwe ngokuthe nkqo kumbhobho othe tyaba, kwiimeko ezizodwa kufuneka ufakelo oluthe tyaba okanye lwe-inclined, ngokubanzi kufuneka longeze inkxaso.Ipleyiti ejikelezayo efakwe eludongeni lwebhokisi ye-insulated kufuneka ihambelane nodonga lwebhokisi le-insulated.

2. Kufuneka ifakwe kufuphi nomhlaba okanye emgangathweni, ukuze kugcinwe kwaye kulungiswe, ukwenzela ukufakelwa kwe-positioner okanye isixhobo sevili lesandla, kufuneka siqinisekise ukuqwalaselwa, ukulungiswa kunye nokusebenza kunye nokulula.

3. Ngokuqhelekileyo ukusetha umbhobho wokudlula, ukwenzela ukusilela kwenkqubo yokulawula ngokuzenzekelayo okanye ukugcinwa ukutshintshela ekusebenzeni ngesandla, kungekhona ukuyeka ukuvelisa.

4. Xa i-handwheel mechanism ifakwe, inokuphinda iqhutywe ngesandla ngokushiya umbhobho wokudlula, kwaye ingasetyenziselwa ukunciphisa ukuvulwa.Xa uyeka ukusebenzisa, i-handwheel machine kufuneka ibuyiselwe kwindawo yokuqala yokungathathi hlangothi ukuze kuququzelelwe ukusebenza okuqhelekileyo kwenkqubo yolawulo oluzenzekelayo.

5. Ufakelo lwevalvu yokulawula umoya, kufuneka lenze isikhokelo sokuhamba okuphakathi kunye nesalathiso esiboniswe ngumzimba wevalve.

6. Ngaphambi kokufakwa kombhobho kufuneka kucoceke ukungcola, i-slag.Emva kokufakela, yenza ukuvula ngokupheleleyo, uhlambulule umbhobho, njl njl kwaye uvavanye ukuqina kwelungu ngalinye.

Iintsilelo ezi-6 eziQhelekileyo zeValve yesitulo esinye soLawulo lwe-Peneumatic:

1.Ivalve yoLawulo ayisebenzi.Iimpazamo kunye nezizathu zezi zilandelayo:

1).Akukho mqondiso, akukho moya.
