Heerkulka shaqada ee waalka waxaa lagu go'aamiyaa shayga waalka.Heerkulka alaabta sida caadiga ah loo isticmaalo ee valves waa sida soo socota:
Heerkulka hawlgalka Valve
Waalka birta ee cawlan: -15 ~ 250 ℃
Waalka birta ah ee la jeexjeexi karo: -15～250℃
Waalka birta-mareenka ah: -30～350℃
Waalka birta ah ee nikkel-ka sare: heerkulka ugu sarreeya ee hawlgalka waa 400 ℃
Waalka birta kaarboon: -29 ℃ 450 ℃, heerkulka lagu taliyey t<425℃ ee JB/T3595-93 heerka
1Cr5Mo, Alloy steel valve: heerkulka ugu sarreeya ee hawlgalka waa 550 ℃
12Cr1MoVA, Alloy steel waalka: heerkulka ugu sareeya ee hawlgalka waa 570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti waalka birta aan fiicnayn: -196℃
Waalka daawaha naxaasta: -273～250℃
Walalka caagga ah (nylon): heerkulka ugu sarreeya ee hawlgalka waa 100 ℃
Waalka caaga ah (polyeter koloriin leh): heerkulka ugu badan ee hawlgalka 100 ℃
Waalka caaga ah (polyvinyl chloride): heerkulka ugu badan ee hawlgalka 60 ℃
Waalka caaga ah (polytrifluorochlorethylene): -60～120℃
Waalka caaga ah (PTFE): -180～150℃
Waalka caagga ah (maalka caagga dabiiciga ah): Heerkulka ugu sarreeya ee shaqeynaya 60℃
Waalka caaga ah ( caag nitrile, neoprene diaphragm valve): heerkulka ugu badan ee hawlgalka waa 80 ℃
Waalka caaga ah (fluorine caag diaphragm valve): heerkulka ugu sarreeya ee hawlgalka waa 200 ℃
Marka caag ama caag loo isticmaalo dahaarka waalka, caabbinta heerkulka caagga iyo balaastiggu waa in ay adkaataa
Xirmooyinka dhoobada, sababtoo ah caabbinta heerkulka liidata, ayaa guud ahaan loo isticmaalaa xaaladaha shaqada ee ka hooseeya 150 ° C.Dhowaan, waxaa soo baxay waalka dhoobada ah ee aad u wanaagsan, kaas oo u adkeysan kara heerkulka sare ee ka hooseeya 1000 ° C.
Walalka galaasku waxay leeyihiin iska caabin heerkul liita waxaana guud ahaan loo isticmaalaa xaaladaha shaqada ee ka hooseeya 90 ° C.
Cadaadiska heerkulka ee waalka dhaldhalaalka waxaa xaddidaya shayga giraanta, iyo heerkulka ugu sarreeya ee hawlgalka kama badna 150 ° C.
Qalabka jirka ee Valve inta badan waxaa ka mid ah: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 taxane ahama birta, K birta shubka malleable, daawaha L aluminium, P 0Cr18Ni9 taxane ahama, PL 00Cr19Ni10 taxane ahama, Q ductile birta, R 0Cr22Ni1 ahama, RL 00Cr17Ni14Mo2 taxane ahama, S caag, T copper iyo copper alloy, Ti titanium iyo alloy titanium, V chromium molybdenum vanadium birta, Z cawl shuban bir.
