良工閥門(mén)代理氣動(dòng)閥門(mén)電磁閥的原理有哪些?

氣動(dòng)閥門(mén)是工業(yè)管路中zui為常見(jiàn)的流體控制設(shè)備,主要由氣動(dòng)執(zhí)行器與閥門(mén)組成,通過(guò)壓縮干凈空氣來(lái)驅(qū)動(dòng)閥門(mén),從而控制管道介質(zhì)的流通和關(guān)斷,且執(zhí)行的速度非??欤ǔS糜诳焖偾袛嗍褂?。氣動(dòng)閥通常配置各種附件,比如電磁閥、氣源處理三聯(lián)件、限位開(kāi)關(guān)、定位器、控制箱等,以實(shí)現(xiàn)就地控制和遠(yuǎn)距離集中控制。如果對(duì)于僅需要開(kāi)與關(guān)作用的兩位閥,電磁閥是必要的配置,電磁閥通過(guò)勵(lì)磁/消磁來(lái)達(dá)到對(duì)氣動(dòng)閥門(mén)開(kāi)/關(guān)的控制。
Pneumatic valve is the most common fluid control equipment in industrial pipeline, which is mainly composed of pneumatic actuator and valve. The valve is driven by compressed clean air to control the flow and shutoff of pipeline medium. The execution speed is very fast, and it is usually used for quick shutoff. Pneumatic valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. If the solenoid valve is a necessary configuration for the two-position valve that only needs to be opened and closed, the solenoid valve can control the opening/closing of the pneumatic valve through excitation/degaussing.
在氣路(或液路)上來(lái)說(shuō),兩位三通電磁閥具有1個(gè)進(jìn)氣孔(接進(jìn)氣氣源)、1個(gè)出氣孔(提供給目標(biāo)設(shè)備氣源)、1個(gè)排氣孔(一般安裝一個(gè)消聲器,如果不怕噪音的話(huà)也可以不裝。兩位五通電磁閥具有1個(gè)進(jìn)氣孔(接進(jìn)氣氣源)、1個(gè)正動(dòng)作出氣孔和1個(gè)反動(dòng)作出氣孔(分別提供給目標(biāo)設(shè)備的一正一反動(dòng)作的氣源)、1個(gè)正動(dòng)作排氣孔和1個(gè)反動(dòng)作排氣孔(安裝消聲器)。 對(duì)于小型自動(dòng)控制設(shè)備,氣管一般選用8~12mm的工業(yè)膠氣管。
In terms of air circuit (or liquid circuit), the two-position three-way solenoid valve has 1 air inlet (connected to the air supply), 1 air outlet (provided to the air supply of the target equipment), 1 air outlet (generally installed with a muffler, if it is not afraid of noise, it can not be installed. The two-position five-way solenoid valve has 1 air inlet (connected to the air supply), 1 positive acting air hole and 1 negative acting air hole (respectively provided to the air supply of the target equipment) One positive action exhaust hole and one negative action exhaust hole (install muffler). For small automatic control equipment, the gas pipe is generally 8~12mm industrial rubber gas pipe.
在電氣上來(lái)說(shuō),兩位三通電磁閥一般為單電控(即單線(xiàn)圈),兩位五通電磁閥一般為雙電控(即雙線(xiàn)圈)。線(xiàn)圈電壓等級(jí)一般采用DC24V、AC220V等。 兩位三通電磁閥分為常閉型和常開(kāi)型兩種,常閉型指線(xiàn)圈沒(méi)通電時(shí)氣路是斷的,常開(kāi)型指線(xiàn)圈沒(méi)通電時(shí)氣路是通的。
Electrically, the two-position three-way solenoid valve is generally single electric control (i.e. single coil), and the two-position five-way solenoid valve is generally double electric control (i.e. double coil). The coil voltage level generally adopts DC24V, AC220V, etc. The two-position three-way solenoid valve is divided into two types: normally closed type and normally open type. Normally closed type means that the air circuit is disconnected when the coil is not powered on, and normally open type means that the air circuit is open when the coil is not powered on.

常閉型兩位三通電磁閥動(dòng)作原理:給線(xiàn)圈通電,氣路接通,線(xiàn)圈一旦斷電,氣路就會(huì)斷開(kāi),這相當(dāng)于“點(diǎn)動(dòng)”。
The action principle of the normally closed two-position three-way solenoid valve: energize the coil and connect the air circuit. Once the coil is powered off, the air circuit will be disconnected, which is equivalent to "inching".
常開(kāi)型兩位三通單電控電磁閥動(dòng)作原理:給線(xiàn)圈通電,氣路斷開(kāi),線(xiàn)圈一旦斷電,氣路就會(huì)接通,這也是“點(diǎn)動(dòng)”。
The action principle of the normally open two-position three-way single electric control solenoid valve: energize the coil and disconnect the air circuit. Once the coil is powered off, the air circuit will be connected, which is also "inching".
兩位五通雙電控電磁閥動(dòng)作原理:給正動(dòng)作線(xiàn)圈通電,則正動(dòng)作氣路接通(正動(dòng)作出氣孔有氣),即使給正動(dòng)作線(xiàn)圈斷電后正動(dòng)作氣路仍然是接通的,將會(huì)一直維持到給反動(dòng)作線(xiàn)圈通電為止。 給反動(dòng)作線(xiàn)圈通電,則反動(dòng)作氣路接通(反動(dòng)作出氣孔有氣),即使給反動(dòng)作線(xiàn)圈斷電后反動(dòng)作氣路仍然是接通的,將會(huì)一直維持到給正動(dòng)作線(xiàn)圈通電為止。這相當(dāng)于“自鎖”(即所謂的記憶功能)。 基于兩位五通雙電控電磁閥的這種特性,在設(shè)計(jì)機(jī)電控制回路或編制PLC程序的時(shí)候,可以讓電磁閥線(xiàn)圈動(dòng)作1~2秒就可以了,這樣可以保護(hù)電磁閥線(xiàn)圈不容易損壞。
The operation principle of the two-position five-way double electric control solenoid valve: if the positive action coil is powered on, the positive action air circuit is connected (the positive action air hole has air). Even if the positive action coil is powered off, the positive action air circuit is still connected, and will continue until the negative action coil is powered on. If the reaction coil is powered on, the reaction air circuit is connected (the reaction air hole has air). Even if the reaction coil is powered off, the reaction air circuit is still connected and will remain until the positive action coil is powered on. This is equivalent to "self-locking" (so-called memory function). Based on this characteristic of the two-position five-way dual-control solenoid valve, when designing the electromechanical control circuit or compiling the PLC program, it is enough to make the solenoid valve coil act for 1-2 seconds, which can protect the solenoid valve coil from being easily damaged.
