CML solenoid valve WH42-G02-B2A-A220-20 is a step by step direct action type, which can complete the electromagnetic control at the same time, and can have a greater impact on the overall working state of the pipeline. Moreover, the use of vacuum solenoid valve can effectively prevent the impact of other irrelevant elements on the pipeline, so as to make the correct working state of the pipeline. When the vacuum solenoid valve is installed on the mechanical vacuum pump, the valve and the pump are connected to the same power supply, and the opening and closing of the pump directly control the opening and closing of the valve. When the pump stops working or the power supply suddenly becomes intertwined, the valve can automatically fill the vacuum * * * and the air inlet passing through the pump into the pump chamber to prevent the pump oil from flowing back to pollute the vacuum. Looking at the external solenoid valves, up to now, they can be divided into three categories, namely, direct action type, recoil type and pilot type, while from the differences in valve flap structure, data and principle, the reverse type can be divided into: diaphragm type recoil solenoid valve and type recoil solenoid valve; The pilot type can also be divided into: pilot type diaphragm solenoid valve, pilot type solenoid valve; From the valve seat and sealing data, it can also be divided into soft sealing solenoid valve, rigid sealing solenoid valve and semi rigid sealing solenoid valve. 1, Principle of direct acting solenoid valve: when the normally closed direct acting solenoid valve is energized, the solenoid coil generates electromagnetic attraction to lift the valve core, so that the closing part can be turned away from the remote opening valve seat sealing pair; When the power is cut off, the electromagnetic force disappears, and the valve is closed by pressing the closing element on the valve seat with spring force. (The normally open type is the opposite) Characteristics: it can work normally under vacuum, negative pressure and zero differential pressure. It can be installed arbitrarily below dn50, but the electromagnetic head has a large volume. For example, the direct acting solenoid valve imported from heri0n can be used for 1.33>10-4mpa vakyòm

Prensip valv solenoid rkul: prensip li se ke aksyon dirèk la ak faz pilòt yo diferan. Lè valv solenoid la kouran, valv oksilyè a vire an premye. Presyon an nan chanm ki pi ba nan valv prensipal la pi gran pase presyon an nan chanm anwo a, ak valv la louvri pa aksyon an similtane nan presyon diferans ak valv solenoid; Nan ka echèk pouvwa, valv oksilyè a dwe pouse pati fèmen a ak fòs prentan oswa presyon mwayen, epi deplase li anba pou fèmen valv la. Karakteristik: Li ka travay tou anba presyon diferans zewo oswa presyon ki wo, men pouvwa a ak volim yo gwo, kidonk aparèy la obligatwa. 3, Prensip pilòt ki opere valv solenoid: lè tiyo pilòt la kouran, fòs solenoid la kondwi valv pilòt la pou louvri valv pilòt la, presyon nan chanm anwo valv prensipal la desann rapidman, fòme yon diferans presyon ant chanm anwo a. ak chanm ki pi ba nan valv prensipal la, ak konte sou presyon an mwayen ankouraje fèmti nan valv prensipal la pou avanse pou pi, valv la louvri; Lè pouvwa a koupe, tiyo pilòt la fèmen pa fòs prentan an, ak presyon mwayen inlet la byen vit antre nan chanm anwo valv prensipal la nan twou pilòt la pou fòme yon presyon diferans, konsa fèmen valv prensipal la. Karakteristik: ti gwosè, pouvwa ki ba, men diferans nan presyon mwayen limite, ak kondisyon an diferans presyon nesesè. Se de pozisyon twa-fason solenoid valv la anjeneral yo itilize ansanm ak actuator a pneumatik aji sèl. De pozisyon yo kontwole: louvri fèmen. Valv twa-fason an gen twa chanèl pou vantilasyon. Anba kondisyon nòmal, yon sèl chanèl konekte ak sous lè a, de lòt chanèl yo konekte ak inlet lè a nan actuator a, ak lòt la konekte ak pò echapman nan actuator la. Prensip k ap travay detaye a ka refere a dyagram prensip k ap travay nan actuator pneumatik aji sèl la. Se de pozisyon senk fason solenoid valv la anjeneral yo itilize ansanm ak doub aji pneumatik actuator la. Valv solenoid de pozisyon senk fason kontwole: louvri fèmen. Valv solenoid senk fason gen senk chanèl pou vantilasyon, youn nan yo ki konekte ak sous lè a, de nan yo ki konekte ak inlet lè a ak priz nan chanm lè ekstèn nan silenn an doub aji, ak de nan yo ki konekte ak inlet lè a ak priz chanm lè pasyèl la. Prensip travay detaye a ka refere yo bay prensip k ap travay nan actuator pneumatik doub aji an tèm de kous lè a (oswa sikwi likid), de pozisyon twa-fason solenoid valv la gen yon sèl inlet lè (konekte ak rezèv lè a), yon sèl. priz lè (pou bay rezèv lè a pou ekipman sib la) ak yon priz lè
