Lub ntsuas kub kuj tseem hu ua qhov hloov pauv kub, uas yog ib hom kev hloov pauv uas feem ntau siv hauv peb lub neej. Raws li lub hauv paus ntsiab lus ntawm kev tsim khoom, cov ntsuas kub feem ntau tuaj yeem muab faib ua plaub hom: snap thermostat, kua expansion thermostat, siab ntsuas kub thiab digital thermostat.
1.Snap Thermostat
Ntau yam qauv ntawm snap thermostats yog sib sau ua ke hu ua KSD, xws li KSD301, KSD302 thiab lwm yam. Qhov ntsuas kub no yog hom tshiab ntawm bimetallic thermostat. Nws yog tsuas yog siv los ua kev sib txuas nrog cov thermal fuse thaum muaj ntau yam khoom siv hluav taws xob cua sov uas muaj kev tiv thaiv overheating. Lub snap thermostat yog siv los tiv thaiv thawj.
2.Liquid Expansion Thermostat
Nws yog qhov tshwm sim ntawm lub cev (qhov hloov pauv) uas thaum qhov kub ntawm cov khoom tswj tau hloov pauv, cov khoom siv (feem ntau yog kua) hauv qhov ntsuas kub ntawm qhov ntsuas kub yuav tsim cov thermal expansion thiab txias contraction, thiab cov tshuaj ntsiav txuas nrog qhov ntsuas kub. ib feem yuav nthuav lossis cog lus. Cov kua expansion thermostat feem ntau yog siv hauv kev lag luam khoom siv hauv tsev, khoom siv hluav taws xob cua sov, kev lag luam tub yees thiab lwm qhov chaw tswj kub.
3.Siab Hom Thermostat
Qhov ntsuas kub zoo no hloov pauv qhov kev hloov pauv ntawm qhov ntsuas kub mus rau qhov hloov pauv ntawm qhov chaw siab lossis ntim los ntawm lub hnab kaw qhov kub thiab capillary ntim nrog qhov ntsuas kub ua haujlwm nruab nrab. Thaum qhov kub ntawm qhov ntsuas kub tau mus txog, qhov kev sib cuag tau raug kaw los ntawm cov khoom siv elastic thiab ceev nrawm nrawm kom ua tiav lub hom phiaj ntawm kev tswj kub tsis siv neeg.
4.Digital Thermostat
Cov ntsuas kub digital ntsuas ntsuas los ntawm kev ntsuas qhov ntsuas kub tsis kam. Feem ntau, platinum hlau, tooj liab hlau, tungsten hlau thiab thermistor yog siv los ntsuas qhov ntsuas kub. Txhua yam ntawm cov resistors muaj nws tus kheej zoo. Cov cua txias hauv tsev feem ntau siv hom thermistor.
