‘0821100013氣動壓力開關(guān)

氣動閥優(yōu)點

1、氣動裝置結(jié)構(gòu)簡單、輕便、安裝維護簡單。介質(zhì)為空氣，較之液壓介質(zhì)來說不易燃燒，故使用安全。

2、工作介質(zhì)是取之不盡的空氣、空氣本身不花錢。排氣處理簡單，不污染環(huán)境，成本低。

3、輸出力以及工作速度的調(diào)節(jié)非常容易。氣缸的動作速度一般小于1M/S，比液壓和電氣方式的動作速度快。

4、可靠性高，使用壽命長。電器元件的有效動作次數(shù)約為百萬次，而一般電磁閥的壽命大于3000萬次，某些質(zhì)量好的閥超過2億次。

5、利用空氣的壓縮性，可貯存能量，實現(xiàn)集中供氣。可短時間釋放能量，以獲得間歇運動中的高速響應(yīng)。可實現(xiàn)緩沖。沖擊負載和過負載有較強的適應(yīng)能力。在一定條件下，可使氣動裝置有自保持能力。

6、全氣動控制具有防火、防爆、防潮的能力。與液壓方式相比，氣動方式可在高溫場合使用。

7.壓縮空氣可集中供應(yīng)，遠距離輸送。

性能要求

1.閥門某一規(guī)格批量制造時，應(yīng)委托有地位性機構(gòu)進行以下性能的：

①閥門在工壓狀況下的啟閉力矩；

②在工壓狀況下，能保證閥門關(guān)閉嚴密的連續(xù)啟閉次數(shù)；

③閥門在管道輸水狀況下的流阻系數(shù)的。

2.閥門在出廠前應(yīng)進行以下的：

①閥門在開啟狀況下，閥體應(yīng)承受閥門工壓值二倍的內(nèi)壓；

②閥門的關(guān)閉狀況下，兩側(cè)分別承受1.1倍閥門工壓值，無滲漏；但金屬密封的蝶閥，滲漏值亦不大于相關(guān)要求。

壓力開關(guān)是一種簡單的壓力控制裝置，當被測壓力達到額定值時，壓力開關(guān)可發(fā)出警報或控制信號。壓力開關(guān)的一般工作原理：是當系統(tǒng)內(nèi)壓力高于或低于額定的安全壓力時，感應(yīng)器內(nèi)膜片片瞬時發(fā)生移動，通過連接導桿推動開關(guān)接頭接通或斷開，當壓力降至或升額定的恢復值時，膜片瞬復位，開關(guān)自動復位，或者簡單的說是當被測壓力超過額定值時，彈性元件的自由端產(chǎn)生位移，直接或經(jīng)過比較后推動開關(guān)元件，改變開關(guān)元件的通斷狀態(tài)，達到控制被測壓力的目的。

壓力開關(guān)用在空壓機上面主要是來調(diào)節(jié)空壓機的起停狀態(tài),通過調(diào)節(jié)儲氣罐內(nèi)的壓力來讓空壓機停機休息,對機器有保養(yǎng)作用.在空壓機工廠調(diào)試的時候,根據(jù)客戶需要調(diào)節(jié)到指定壓力,然后設(shè)定一個壓差.例如,壓縮機開始啟動,向儲氣罐打氣,到壓力10kg的時候,空壓機停機或者卸載,當壓力到7kg的時候空壓機又開始啟動,此間有一個壓力差,這個過程就可以讓壓縮機休息一下,達到保護空壓機的作用.由電動機直接驅(qū)動壓縮機，使曲軸產(chǎn)生旋轉(zhuǎn)運動，帶動連桿使活塞產(chǎn)生往復運動，引起氣缸容積變化。由於氣缸內(nèi)壓力的變化，通過進氣閥使空氣經(jīng)過空氣濾清器（****）進入氣缸，在壓縮行程中，由於氣缸容積的縮小，壓縮空氣經(jīng)過排氣閥的作用，質(zhì)量流量計經(jīng)排氣管，單向閥（止回閥）進入儲氣罐，當排氣壓力達到額定壓力0.7MPa時由壓力開關(guān)控制而自動停機。
