Weelka shaabadaha sheyga waa qayb muhiim ah oo ka mid ah Valve-ka. Waa maxay qalabka xiisaha leh? Waxaan ognahay in qalabka 'Valve The Wing The Wing' ay u qaybsan yihiin laba qaybood: bir iyo bir la'aan. Hordhac kooban ayaa ah in la soo bandhigo xaaladaha isticmaalka ee agabyada xidhitaanka ee kaladuwan, iyo sidoo kale noocyada vadve ee sida caadiga ah loo isticmaalo.
1. Caadi jilicsan
Guryaha dhameystiran ee caagga jilicsan sida caabbinta saliidda, iska caabbinta heerkulka iyo iska caabbinta daadashada ayaa ka fiican kuwa caagga ah ee dabiiciga ah. Guud ahaan, heerkulka isticmaalka caagga isku-darka ah waa t t t t≤≤50 ℃, iyo heerkulka caagga ah ee dabiiciga ah waa t t ≤60 ℃Palval Sheld Sent Leh, tuunbooyinka diaphragm,rUbber fadhiga suumanka, rUbber fadhiga jeegaynta (Hubi tuubooyinka), jajab ku wareeji iyo tuubooyin kale oo leh cadaadis weyn oo ah pn≤mpa.
2. Nylon
Nylon waxay leedahay astaamaha is-caabbinta khafiifka ah iyo iska caabbinta suuxdinta wanaagsan. Nylon waxaa badanaa loo isticmaalaa tuubooyinka kubadaha iyo xargaha gladaha leh heerkulka to≤90 ℃ iyo cadaadiska loo yaqaan 'pn p' pn≤32mpa.
3. PtFE
PTFE waxaa badanaa loo isticmaalaa tuubbooyinka glube,albaabka albaabka, Valves kubadaha, iwm
4. Bir shiday
Bir bir ah ayaa loo isticmaalaaalbaabka albaabka, Globe Valve, ku dheji valve, iwm.
5. Babbitt Iceoy
Babbit Alkoy waxaa loo isticmaalaa ammone glado valve leh heerkul t-70 ~ 150 ℃ iyo cadaadiska guud ee pn≤2.5mpa.
6. Alloy cootect
Qalabka caanka ah ee loo yaqaan 'Copper' ee 'Copper' waa 6-6-3 naxaas ah iyo 58-2-2 manganese naxaas. Alloy naxaas ah ayaa leh caabbinta wanaagsan oo waxay ku habboon tahay biyaha iyo uumiga leh heerkulka t t≤200 ℃ iyo cadaadiska loo yaqaan 'pn '1.6mpa. Waxaa badanaa loo isticmaalaa gudahaalbaabka albaabka, globe valves,Hubi tuubooyinka, tuur tuunbooyinka, iwm.
7. Chrome steel bir ah
Darajooyinka caadiga ah ee la istcimaalo ee chromium-ka baalal la'aanta birta waa 2c13 iyo 3Cr13, kuwaas oo la daadshay oo xanaaqsan, oo ay leeyihiin iska caabbinta hufnaanta wanaagsan. Waxaa badanaa loo isticmaalaa fiilooyinka loogu talagalay warbaahinta sida biyaha, uumiga iyo batroolka oo leh heerkul t ee heer≤450 ℃ iyo cadaadiska guud ee pn≤32mpa.
8. Chromium-nickel-tittanium-ka birta ah
Heerka caadiga ah ee loo adeegsado ee koromium-nicel-titanium-ka 'birta aan sal lahayn bir waa 1cr18ni9ti, oo leh iska caabbinta suuxdinta wanaagsan, iska caabbinta nabarrada iyo iska caabinta kuleylka. Waxay ku habboon tahay in uumiga, nitric acid iyo warbaahinta kale ee leh heerkulka heerka heerkulka ah ee pn≤6.4mpa, oo loo adeegsaday globe valve, etc valve, iwm.
9. bir bir ah
Heerka caadiga ah ee loo isticmaalo birta nitrid ee birta ah waa 38cremola, oo leh iska caabbinta suuxdinta wanaagsan iyo xoqida iska caabbinta ka dib daaweynta xannaaneynta. Sida caadiga ah loo isticmaalo albaabka korantada ee korantada leh ee heerkulka t ee heerkulka t≤540 ℃ iyo cadaadis weyn pn≤0mpa.
10. Birta
Bixinta si toos ah uga baaraandega dusha sare ee jirka weelka waalka ama jirka diskiga, ka dibna waxay fulisaa daaweyn dusha sare ah, dusha sare ee xirashada waxay leedahay iska caabin wanaagsan. Loo adeegsaday tuubada weelka tamarta ee korantada.
