Mmezi nke ihe na-eduzi njikwa okpomọkụ mpịachi
Mahadum injinịa na teknụzụ nke Shanghai emepụtala ụdị thermostat ọhụrụ dabere na paraffin thermostat na cylindrical coil spring coil cylindrical memory alloy dị ka ihe na-achịkwa okpomọkụ. Mgbe okpomọkụ silinda mmalite nke thermostat dị ala, spring bias na-apịachi spring alloy iji mechie valvụ isi ma mepee valvụ enyemaka maka obere mgbasa. Mgbe okpomọkụ coolant rịrị elu ruo uru ụfọdụ, spring alloy memory na-agbasa ma na-apịachi spring bias iji mepee valvụ isi nke thermostat. Ka okpomọkụ coolant na-abawanye, mmeghe nke valvụ isi na-abawanye nwayọ nwayọ, valvụ enyemaka na-emechikwa nwayọ nwayọ maka nnukwu mgbasa.
Dịka ngalaba njikwa okpomọkụ, ihe nchekwa ebe nchekwa na-eme ka ọrụ mmeghe valvụ dị nro ma e jiri ya tụnyere mgbanwe okpomọkụ, nke na-enyere aka ibelata mmetụta nrụgide okpomọkụ na blọk silinda nke mmiri oyi dị ala na tankị mmiri na-akpata mgbe injin ọkụ dị n'ime malitere, ma melite ndụ ọrụ nke thermostat. Agbanyeghị, a na-agbanwe thermostat site na thermostat wax, nhazi nhazi nke ihe na-eduzi njikwa okpomọkụ na-ejedebe ruo n'ókè ụfọdụ.
Mmezi nke valvụ mpịachi
Igwe thermostat ahụ nwere mmetụta na-akụda mmiri na ihe na-ekpo ọkụ. Enweghị ike ileghara mfu ike nke injin ọkụ dị n'ime nke ihe na-ekpo ọkụ nke na-asọfe site na thermostat anya. Na 2001, Shuai Liyan na Guo Xinmin nke Mahadum Shandong Agricultural mepụtara valvụ nke thermostat ahụ dị ka silinda dị gịrịgịrị nwere oghere na mgbidi akụkụ, mepụta ọwa mmiri mmiri site na oghere dị n'akụkụ na oghere dị n'etiti, wee họrọ ọla kọpa ma ọ bụ aluminom dị ka ihe eji eme valvụ ahụ, Mee ka elu valvụ ahụ dị nro, ka o wee belata nguzogide ma melite arụmọrụ ọrụ nke thermostat ahụ.
