A na-ekpebi okpomọkụ na-arụ ọrụ nke valve site na ihe nke valve.Ọnọdụ okpomọkụ nke ihe ndị a na-ejikarị eme ihe maka valves bụ ndị a:
Ọnọdụ okpomọkụ na-arụ ọrụ Valve
Valve ígwè nkedo isi awọ: -15 ~ 250 ℃
valvụ nke nkedo a na-emegharị emegharị: -15～250 ℃
ductile ígwè valvụ: -30 ~ 350 ℃
Akwa nickel nkedo ígwè valve: okpomọkụ kachasị arụ ọrụ bụ 400 ℃
Carbon ígwè valvụ: -29 ~ 450 ℃, na-atụ aro okpomọkụ t <425 ℃ na JB / T3595-93 ọkọlọtọ
1Cr5Mo, alloy ígwè valvụ: kacha arụ ọrụ okpomọkụ bụ 550 ℃
12Cr1MoVA, alloy ígwè valvụ: kacha arụ ọrụ okpomọkụ bụ 570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti igwe anaghị agba nchara valvụ: -196 ~ 600℃
Ọla kọpa alloy valvụ: -273 ~ 250 ℃
Plastic valve (nylon): okpomọkụ kachasị arụ ọrụ bụ 100 ℃
Plastic valvụ (chlorinated polyether): kacha arụ ọrụ okpomọkụ 100 ℃
Plastic valve (polyvinyl chloride): kacha arụ ọrụ okpomọkụ 60 ℃
Plastic valve (polytrifluorochlorethylene): -60 ~ 120 ℃
Plastic valve (PTFE): -180 ~ 150 ℃
valvụ rọba (valvụ roba diaphragm nkịtị): Okpomọkụ kacha arụ ọrụ 60 ℃
Plastic valve (rọba nitrile, valvụ neoprene diaphragm): okpomọkụ kachasị arụ ọrụ bụ 80 ℃
Plastic valve (fluorine rubber diaphragm valve): okpomọkụ kachasị arụ ọrụ bụ 200 ℃
Mgbe a na-eji rọba ma ọ bụ plastik mee ihe maka mkpuchi valvụ, nguzogide okpomọkụ nke rọba na plastik ga-emeri
A na-ejikarị valvụ seramiiki, n'ihi na-eguzogide okpomọkụ ha na-adịghị mma, na-ejikarị arụ ọrụ n'okpuru 150 ° C.N'oge na-adịbeghị anya, valvụ seramiiki na-arụ ọrụ nke ọma apụtala, nke nwere ike iguzogide okpomọkụ dị elu n'okpuru 1000 Celsius.
A na-eji valves iko na-eguzogide okpomọkụ na-adịghị mma ma a na-ejikarị ya eme ihe na ọnọdụ ọrụ n'okpuru 90 Celsius.
Mgbochi okpomọkụ nke valvụ enamel na-ejedebe site na ihe nke mgbanaka akara, na oke ọrụ okpomọkụ adịghị agafe 150 ° C.
Valve ahu ihe tumadi gụnyere: C carbon steel, I 1Cr5Mo chromium molybdenum ígwè, H Cr13 usoro igwe anaghị agba nchara, K malleable nkedo ígwè, L aluminum alloy, P 0Cr18Ni9 usoro igwe anaghị agba nchara, PL 00Cr19Ni10 usoro igwe anaghị agba nchara, Q ductile ígwè, R 0Cr12Ni1 igwe anaghị agba nchara, RL 00Cr17Ni14Mo2 usoro igwe anaghị agba nchara, S plastic, T ọla kọpa na ọla kọpa alloy, Ti titanium na titanium alloy, V chromium molybdenum vanadium ígwè, Z isi awọ nkedo ígwè.
