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 lub tshuab nqus tsev

Lub hauv paus ntsiab lus ntawm recoil solenoid valve: nws lub hauv paus ntsiab lus yog qhov kev txiav txim ncaj qha thiab cov theem pib sib txawv. Thaum lub solenoid valve yog energized, lub auxiliary valve yog tig ua ntej. Lub siab ntawm lub hauv qab chamber ntawm lub ntsiab valve yog siab dua lub siab ntawm lub sab sauv chamber, thiab lub valve yog qhib los ntawm lub simultaneous txiav txim ntawm txawv siab thiab solenoid valve; Nyob rau hauv cov ntaub ntawv ntawm lub hwj chim tsis ua hauj lwm, lub auxiliary valve yuav tsum thawb lub kaw qhov chaw nrog lub caij nplooj ntoos hlav quab yuam los yog nruab nrab siab, thiab txav nws downward kaw lub valve. Nta: Nws kuj tuaj yeem ua haujlwm nyob rau hauv xoom qhov sib txawv los yog siab, tab sis lub zog thiab ntim loj, yog li yuav tsum muaj cov cuab yeej siv. 3, Lub hauv paus ntsiab lus ntawm tus tsav ua haujlwm solenoid valve: thaum tsav lub valve yog lub zog, lub zog solenoid tsav lub valve qhib lub tsav valve, lub siab nyob rau hauv lub sab sauv ntawm lub ntsiab valve poob sai heev, tsim lub siab sib txawv ntawm lub sab sauv chamber. thiab sab qis ntawm lub ntsiab valve, thiab tso siab rau qhov nruab nrab siab los txhawb qhov kaw ntawm lub ntsiab valve kom txav mus, lub valve qhib; Thaum lub hwj chim raug txiav tawm, tus tsav lub valve raug kaw los ntawm lub caij nplooj ntoos hlav quab yuam, thiab lub inlet nruab nrab siab sai sai nkag mus rau lub sab sauv ntawm lub ntsiab valve los ntawm lub pilot qhov los tsim ib tug sib txawv siab, yog li kaw lub ntsiab valve. Nta: me me, tsis tshua muaj zog, tab sis qhov nruab nrab siab sib txawv yog txwv, thiab lub siab sib txawv yog tsim nyog. Ob txoj haujlwm peb-txoj kev solenoid valve feem ntau yog siv ua ke nrog ib leeg ua yeeb yam pneumatic actuator. Ob txoj haujlwm yog tswj tau: qhib kaw. Peb-txoj kev valve muaj peb txoj hauv kev rau qhov cua. Raws li ib txwm muaj, ib lub channel txuas nrog cov cua qhov chaw, lwm ob txoj kev txuas nrog cov cua nkag ntawm lub actuator, thiab lwm qhov yog txuas nrog qhov chaw nres nkoj ntawm lub actuator. Cov ncauj lus kom ntxaws ua haujlwm tuaj yeem xa mus rau daim duab qhia kev ua haujlwm ntawm ib qho kev ua haujlwm pneumatic actuator. Ob txoj hauj lwm tsib txoj kev solenoid valve feem ntau yog siv ua ke nrog ob lub pneumatic actuator. Ob txoj haujlwm tsib txoj kev solenoid valve yog tswj tau: qhib kaw. Lub tsib txoj kev solenoid valve muaj tsib txoj hauv kev rau qhov cua, ib qho yog txuas nrog cov cua qhov chaw, ob qho tib si txuas nrog cov cua nkag thiab qhov hluav taws xob ntawm sab nraud cua chamber ntawm ob lub tog raj kheej ua haujlwm, thiab ob qho tib si txuas nrog. cua inlet thiab qhov hluav taws xob ntawm ib nrab cua chamber. Cov ncauj lus kom ntxaws txog kev ua haujlwm tuaj yeem raug xa mus rau lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ob lub pneumatic actuator nyob rau hauv cov nqe lus ntawm huab cua Circuit Court (los yog kua Circuit Court), Ob txoj hauj lwm peb-txoj kev solenoid valve muaj ib tug cua inlet (txuas mus rau lub cua mov), ib tug cua qhov hluav taws xob (kom muab cov pa cua rau cov khoom siv lub hom phiaj) thiab ib lub qhov hluav taws xob cua
