日本SMC消聲器/排氣潔凈器只能作全開和全關(guān),不能作調(diào)節(jié)和節(jié)流。閘板有兩個密封面,常用的模式閘板閥的兩個密封面形成楔形、楔形角隨閥門參數(shù)而異,通常為50,介質(zhì)溫度不高時為2°52'。

楔式閘閥的閘板可以做成一個整 體，叫做剛性閘板；也可以做成能產(chǎn)生微量變形的閘板,以改善其工藝性,彌補密封面角度在加工過程中產(chǎn)生的偏差,這種閘板叫做彈性閘板。閘閥關(guān)閉時,密封面可以只依靠介質(zhì)壓力來密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的,即閥門關(guān)閉時，要依靠外力強行將閘板壓向閥座,以保證密封面的密封性。

SMC真空發(fā)生器的性能與噴管的小直徑，收縮和擴散管的形狀，通徑及其相應(yīng)位置和氣源壓力大小等諸多因素有關(guān)。 ①大吸入流量qv2max的特性分析 ②吸入口處壓力Pv的特性分析 ③在吸入口吵*封閉的條件下，對特定條件下吸入口處壓力Pv與吸入流量之間的關(guān)系 ④擴散管的長度應(yīng)保證噴管出口的各種波系充分發(fā)展，使擴散管道出口截面上能獲得近似的均勻流動。 ⑤吸著響應(yīng)時間與吸附腔的容積有關(guān)(包括擴散腔，吸附管道及吸盤或密閉艙容積等)，吸附表面的泄漏量與所需吸入口處壓力的大小有關(guān)

從催化轉(zhuǎn)換器出來就連接到消聲器了，消聲器橫截面是一個圓形或者橢圓形的物體，多用薄鋼板焊制，裝在排氣系統(tǒng)的中部或者后部位置上，它內(nèi)部有一系列隔板、腔室、孔管和管道，利用聲波反射互相干擾抵消的現(xiàn)象，使聲能逐漸消弱 ，用以隔離和衰減排氣門每次打開時產(chǎn)生的脈動壓力。

 使用維護須知
⒈使用前注意檢查元件是否損壞,然后安裝使用.
⒉安裝時,請注意氣體流動方向及接管是否正確,電壓是否符合要求.
⒊請注意防塵,建議氣口安裝消聲器或消聲節(jié)流閥.
⒋連接管路時,并注意消除管接頭,管子內(nèi)的金屬顆粒,粉塵及油污等
顧名思義，消聲器就是用來消除排氣的噪聲，使車輛行駛起來更寧靜。一般消聲器中會有數(shù)個膨脹室，引擎排放出來的廢氣經(jīng)過數(shù)個膨脹程序后，會使得排氣脈沖緩和而消除噪聲。然而，由于氣體在消聲器路徑復(fù)雜，換言之也就是消聲器降低了排氣的順暢性，所以也會略略影響引擎性能。有些人會自行改裝直通式排氣尾管，這樣雖然稍稍提升引擎性能，卻會大大增加排氣噪聲，所以這是不值得肯定也是違反交通規(guī)定的行為。
