Bidirectional nyuaj foob npauj npaim valveyog hlau rau hlau kaw.Nws kuj tuaj yeem yog hlau foob nplhaib rau hlau kaw lossis stainless hlau phaj foob nplhaib rau hlau kaw.Ntxiv nrog rau kev tsav tsheb fais fab, ob txoj kev nyuaj foob npauj npaim valve tseem tuaj yeem tsav manually, pneumatically, thiab lwm yam.
Lub discob txoj kev hlau foob npauj npaim valveyog ntsia rau hauv txoj kab uas hla ntawm cov kav dej.Nyob rau hauv lub cylindrical channel ntawm npauj npaim valve lub cev, lub disc rotates nyob ib ncig ntawm lub axis, thiab lub tig lub kaum sab xis ntawm 0 ° thiab 90 °.Lub valve qhib tag nrho thaum lub disc tig mus rau 90 °.
Muab faib los ntawm cov qauv txheej txheem: nws muab faib ua lub hauv paus sealing npauj npaim valve, ib qho eccentric sealing npauj npaim valve, ob chav eccentric sealing npauj npaim valve thiabpeb eccentric sealing npauj npaim valve.
Muab faib los ntawm kev sib khi cov ntaub ntawv saum npoo: nws tuaj yeem muab faib ua ob txoj hauv kev nyuaj sealing npauj npaim li qub, uas lub ntsej muag sealing yog tsim los ntawm cov khoom tsis yog xim hlau lossis cov khoom siv hlau tawv rau cov khoom tsis yog xim hlau;thiab tseem muab faib ua hlau nyuaj sealing npauj npaim li qub, uas lub ntsej muag sealing yog tsim los ntawm cov khoom siv hlau nyuaj rau cov khoom siv hlau nyuaj.
Cia, installation thiab siv
1. Ob qhov kawg ntawm lub valve yuav tsum tau thaiv thiab khaws cia rau hauv chav qhuav thiab qhov cua.Nws yuav tsum tau kuaj xyuas tsis tu ncua rau lub sijhawm ntev cia.
2.Lub valve yuav tsum tau muab ntxuav ua ntej kev teeb tsa kom tshem tawm qhov tsis xws luag thaum lub sijhawm thauj mus los.
3. Thaum lub sij hawm installation, cov cim ntawm lub valve yuav tsum tau kuaj xyuas.Thiab tshwj xeeb yuav tsum tau them nyiaj rau qhov kev taw qhia ntws ntawm qhov nruab nrab yog raws li cov cim ntawm lub valve.
4. Rau cov npauj npaim li qub nrog hluav taws xob actuator, nws yuav tsum tau muab sau tseg tias qhov kev sib txuas ntawm lub zog hluav taws xob yuav tsum ua raws li cov lus qhia ntawm cov khoom siv hluav taws xob.
Tej yam ua txhaum, ua rau thiab tshem tawm txoj kev
1. Cov dej ntws tawm ntawm qhov muab tub lim
Yog hais tias cov txiv ntseej ntawm lub pob nias lub phaj tsis nruj los yog nruj tsis sib xws, cov txiv ntseej tuaj yeem nruj kom zoo.Yog tias qhov xau txuas ntxiv, qhov ntim ntawm cov ntim yuav tsis txaus.Lub sijhawm no, cov khoom ntim tuaj yeem thauj khoom dua thiab tom qab ntawd nruj cov txiv ntoo.
2. Cov dej ntws tawm ntawm qhov sib khi ntawm lub cev valve thiab phaj phaj
1) Ntxuav cov av sandwiched ntawm lub sealing nto.
2) Yog hais tias lub sealing nto puas, regrind los yog machining thiab zom lub valve lub cev dua tom qab kho vuam.
3) Yog tias txoj hauj lwm eccentric tsis tsim nyog, kho qhov eccentric txoj hauj lwm mus rau ib qho chaw tsim nyog thaum lub sij hawm installation.
