Isahluko semveliso ye-Taike ye-elastiki yesihlalo sevalve yesango

Iimpawu zeMveliso:

1. Umzimba wenziwe nge-high-grade nodular cast iron, eyanciphisa ubunzima nge-20% ukuya kwi-30% xa kuthelekiswa ne-valve yesango yendabuko.

2. Uyilo oluphambili lwaseYurophu, ulwakhiwo olunengqiqo, ukufakela okufanelekileyo kunye nokugcinwa.

3. I-disc ye-valve kunye ne-screw yenzelwe ukuba ilula kwaye isebenzise, ​​kwaye i-torque yokuvala incinci, malunga ne-50% ephantsi kunomgangatho wendabuko.

4. Umphantsi wevalve yesango uthatha idizayini efanayo esezantsi-ezantsi njengoko umbhobho uphantsi, kwaye xa uvaliwe, isantya sokuhamba siya kukhawuleza kwaye sihlambe i-debris ngaphandle kokwenza umonakalo kwi-flap yevalve kunye nokubangela ukuvuza kwenyama.

5. I-valve disc ithatha irabha ephezulu yomgangatho wamanzi okusela kwi-encapsulation yonke. Itekhnoloji yerabha ephuculweyo ye-vulcanization yenza ukuba idiskhi yevalvu ivuzeke ukuba iqinisekise ubungakanani bejometri echanekileyo, kwaye irabha kunye ne-ductile castings zinokuncamathela okuqinileyo, akukho lula ukuba ziwe kwaye zibe nokunwebeka okuhle.

6. Umzimba wevalve wenziwe ngokusabeka okuphambili, kwaye imilinganiselo yejiyometri echanekileyo yenza ukuba imilinganiselo efanelekileyo yesivalo somzimba ivalwe ngokupheleleyo.

Inkcazo eneenkcukacha:

I-RV (H, C, R) I-valve ye-X luhlobo lwesango lokutywinwa kwesihlalo esilastiki kunye ne-encapsulation edibeneyo ye-disc. Ivalve ineengenelo zokutshintsha ukukhanya, ukutywinwa okuthembekileyo, akukho lula ukuqokelela inkunkuma, ukumelana nokubola, akukho mhlwa, kunye nenkumbulo entle yerabha elastiki. Ingasetyenziswa ngokubanzi kwiindidi ezahlukeneyo zokubonelela ngamanzi kunye nemibhobho yokuhambisa amanzi njengezixhobo zokuthintela okanye zokulawula.

ipharamitha yobugcisa:

Izinto ezisetyenzisiweyo: i-iron ductile

Uluhlu lobungakanani: DN50mm～DN600mm

Iqondo loxinzelelo: 1.0 MPa～2.5MPa

Uluhlu lobushushu: -10℃—80℃

Indawo esebenzayo: amanzi acocekileyo, ugutyulo

Sebenzisa ithuba:

Ivalve yesango lokutywinwa kwesihlalo esiqinileyo ilungele unikezelo lwamanzi ngokubanzi kunye ne-drainage, ukufudumeza kwe-HVAC kunye nokuphefumla, ukulwa nomlilo kunye neenkqubo zokunkcenkceshela.
