Switsundzuxo swa ku vekiwa ka ti check valve

Ku kambela ti valve, leyi tlhelaka yi tiviwa tanihiti valve to kambelakumbe ti check valves, ti tirhisiwa ku sivela ku tlhelela endzhaku ka media eka phayiphi. Valve ya milenge ya suction off ya pompo ya mati na yona yi wela eka xiyenge xa ​​ti check valves. Swiphemu swo pfula na swo pfala swititshege hi ku khuluka na matimba ya medium kuva yi pfula kumbe ku pfala hi yoxe, leswaku xitirhisiwa xinga khuluki xitlhelela endzhaku. Ti check valves ti wela eka xiyenge xa ​​automatic valve, leti tirhisiwaka ngopfu eka tiphayiphi laha medium yi khulukaka eka tlhelo rin’we, naswona yi pfumelela ntsena medium ku khuluka eka tlhelo rin’we ku sivela timhangu.

Hikuya hi xivumbeko, check valve yinga avanyisiwa hi tinxaka tinharhu: lifting check valve, .swing check valve yo kambelanavalve yo kambela phaphatani. Ti check valve to tlakusa tinga avanyisiwa hi ti vertical check valves na ti horizontal check valves.

Kuna tinxaka tinharhu taswing check valves: ti valve to kambela ta single-lobe, ti check valve ta ti flap timbirhi na ti valve to kambela ta multi-flap.

Valve yo kambela phaphatani i valve yo kambela leyi kongomeke, naswona ti check valve letinga laha henhla tinga avanyisiwa hi tinxaka tinharhu: threaded connection check valve, flange connection check valve na welded check valve.

Ku fanele ku tekeriwa enhlokweni timhaka leti landzelaka eka ku vekiwa ka ti-check valve:

1. U nga endli leswakuvalve yo kambelarhwala ntiko eka phayiphi, naswona valve leyikulu yo kambela yifanele ku seketeriwa hiku tiyimela leswaku yinga khumbeki hi ntshikelelo lowu endliwaka hi phayiphi.

2. Hi nkarhi wa ku vekiwa, nyikela nyingiso eka tlhelo ra ku khuluka ka le xikarhi ku fanele ku fambisana na tlhelo ra museve lowu vhotiweke hi miri wa valve.

3. Valve yo kambela ya lifting vertical flap yifanele ku vekiwa eka phayiphi leyi yimisiweke.

4. Valve yo kambela ya lifting horizontal flap yifanele ku vekiwa eka phayiphi ya horizontal. Xana i yini valve yo kambela leyi yimisiweke? Ti vertical check valves titirhisiwa ngopfu eka tisisiteme laha swilaveka ku sivela ku tlhelela endzhaku ka media, kufana na outlet ya pompo, makumu yo tata mati yo hisa, na makumu yo koka ya centrifugal pump. Ntirho wa yona i ku sivela switandzhaku leswi nga humelelaka kusuka eka ku khuluka ka le ndzhaku ka xitirhisiwa, xikombiso, loko ndzhawu yo huma ya pompo yinga hlomisiwanga hi valve yo kambela leyi yimisiweke, mati yo vuyela ya rivilo lerikulu yata vanga nkucetelo lowukulu eka impeller ya pompo loko pompo yi yima hi xitshuketa; Loko vertical check valve (foot valve) yinga vekiwanga eka makumu yo koka ya pompo ya centrifugal, pompo yifanele ku tatiwa nkarhi wun’wana na wun’wana loko pompo yi pfuriwa.

Swivutiso swo tala, u nga tihlanganisa na TWS VALVE leyi hi maily yi humesakaresilent seated phaphatani valve, valve ya gede, valve yo kambela, Y-strainer, na swin’wana.
