Lub expansion valve yog clogged, lub tub yees cov nyhuv tsis zoo, muaj te tom qab lub valve, thiab lub compressor tsis ua hauj lwm ib txwm. Lub expansion valve yog ib qho tseem ceeb nyob rau hauv lub tub yees system, feem ntau ntsia nruab nrab ntawm cov kua cia tank thiab evaporator. Lub expansion valve ua rau nruab nrab-kub thiab high-pressure kua refrigerant dhau los ntawm nws throttling los ua low-temperature thiab low-pressure wet steam, and the refrigerant absorbs heat in the evaporator to achieve the cooling effect. Lub expansion valve muaj peb ntu: lub cev lub cev, qhov ntsuas kub thiab qhov sib npaug ntawm lub raj.
Feature ntawm expansion valve:
1. Lub expansion valve adopts ob-flow balanced orifice nrog advanced qauv.
2. Expansion valve Vim yog kev txais yuav ntawm dual-channel thermal expansion valve, lub tub yees system txuag tus naj npawb ntawm expansion li qub, kos li qub thiab solenoid li qub.
3. Ob txoj kev sib npaug ntawm qhov nthuav dav valve ua rau qhov zoo li qub superheat hloov nrog lub condensing siab los yog lub siab poob los ntawm qhov chaw nres nkoj valve.
4. Lub superheat degree ntawm expansion valve yog ruaj khov, uas ua rau lub kaw lus khiav ruaj khov. 5. Lub expansion valve yog tsim rau ntau yam kev xav tau kev ua haujlwm xws li tub yees thiab cua txias.
