Taw qhia txog Valve cov ntaub ntawv cov ntaub ntawv-TWS Valve

Valve cov khoom lag luam yog qhov tseem ceeb ntawm valve seading. Cov ntaub ntawv valve yog dab tsi? Peb paub tias cov khoom siv hluav taws xob nplhaib sib faib ua ob pawg: hlau thiab tsis yog hlau. Cov hauv qab no yog cov lus qhia luv luv rau kev siv cov xwm txheej ntawm cov ntaub ntawv sealing, nrog rau cov hom valve.

1. Roj hmab roj hmab

Cov roj hmab muaj kev nkag siab ntawm cov roj hmab hluavtaws xws li cov roj tsis kam, kub tsis kam thiab corrosion tsis zoo dua li cov roj hmab ntuj. Feem ntau, siv kub ntawm cov roj hmab hluavtaws yog t≤60 ℃ .rub yog siv rau lub ntiaj teb li qub,Roj Hmab Rooj Zaum Valve, diaphragm li qub,rUbber Seated Npauj Npaim Valve, rUbber Zaum Viav Vias Kos Valve (Saib xyuas li qub), Pinch li qub thiab lwm yam li qub nrog rau lub sijhawm zoo siab PN6MPA.

2. Nylon

Nylon muaj cov yam ntxwv ntawm me me txhuam coefficient thiab zoo corrosion tsis kam. Nylon feem ntau yog siv rau pob li qub thiab lub ntiaj teb li qub nrog T≤GIN siab PN pressure≤ pressure PN02MPA.

3. PTFE

PTFE feem ntau siv rau cov ntiaj teb li qub,Rooj vag Li Qub, pob li qub, thiab lwm yam. Nrog rau qhov ntsuas T≤232 ℃ thiab nominal siab pn6.4MPA.

4. Nrhoo Hlau

Cam khwb cia hlau yog siv raurooj vag valve, globe valve, plug valve, etc. for temperature t≤100℃, nominal pressure PN≤1.6MPa, gas and oil.

5. Babbitt alloy

Babbitt alloy yog siv rau ammonia ntiaj teb valve nrog T-70 ~ 150 ℃ thiab nominal siab Pn ≤2.5MPA.

6. Copper alloy

Cov ntaub ntawv nquag rau cov ntawv luam tawm tooj liab yog 6-6-3 tin bronze thiab 58-2-2 manganese brass. Tooj liab alloy muaj kev coj zoo thiab haum rau dej thiab ncu nrog lub hnub nyoog ntawm cov kub t≤200 ℃ thiab nominal siab pn1.6mpa. Nws feem ntau siv nyob rau hauvRooj vag Li Qub, lub ntiaj teb li qub,Saib xyuas li qub, plug li qub, thiab lwm yam.

7. Chrome stainless hlau

Cov kev siv cov qib ntawm chromium stainless hlau yog 2C13 thiab PC13, uas tau quenched thiab npau taws heev. Nws feem ntau yog siv nyob rau hauv li qub rau media xws li dej, chav thiab roj av nrog kub thiab nominal siab pn32mpa.

8. Chromium-npib tsib xee-Titanium Stainless Hlau

Cov feem ntau yog siv qib ntawm chromium-npib tsib xee-titanium stainless hlau yog 1cr18ni99i, uas muaj zoo corrosion tsis kam, erosion tsis kam thiab kub tsis kam. Nws yog qhov haum rau cov chav, nitric acid thiab lwm yam xov xwm nrog kub thiab cov nominal siab pn6.4MPA, siv rau lub ntiaj teb valve, pob valve, thiab lwm yam.

9. NITrided Hlau

Cov txheej txheem siv ntawm nitrided steel yog 38crmoala, uas muaj cov zoo corrosion tsis kam thiab kos tsis kam tom qab kev kho mob carburizing. Feem ntau siv nyob rau hauv lub zog chaw nres tsheb vag lub vag valve nrog lub zog TENITCH nrog TIT10MPA.

10. Boronizing

Boronizing ncaj qha cov txheej txheem ntawm kev sib khi saum npoo ntawm cov khoom ntawm lub cev lossis disc lub cev, thiab tom qab ntawd nqa tawm cov khoom nto nto muaj qhov chaw zoo tau hnav tsis kam. Siv nyob rau hauv lub chaw nres tsheb fais fab tsoo lub qhov rooj.
