壓(ya)電(dian)(dian)(dian)(dian)閥是(shi)利用壓(ya)電(dian)(dian)(dian)(dian)效應制(zhi)(zhi)成(cheng)的(de)一(yi)種真空氣體流(liu)量調(diao)節閥。壓(ya)電(dian)(dian)(dian)(dian)閥的(de)部(bu)件是(shi)由(you)壓(ya)電(dian)(dian)(dian)(dian)陶瓷制(zhi)(zhi)成(cheng)的(de)具有(you)壓(ya)電(dian)(dian)(dian)(dian)特性的(de)膜片。當(dang)在壓(ya)電(dian)(dian)(dian)(dian)陶瓷膜片上施加一(yi)控制(zhi)(zhi)電(dian)(dian)(dian)(dian)壓(ya)時(shi)，它將會(hui)產生正比于外加電(dian)(dian)(dian)(dian)壓(ya)值大小的(de)變(bian)形。同(tong)時(shi)，帶動(dong)密(mi)封墊移動(dong)。于是(shi)壓(ya)電(dian)(dian)(dian)(dian)閥流(liu)導產生變(bian)化，從而改變(bian)氣體通過壓(ya)電(dian)(dian)(dian)(dian)閥的(de)流(liu)量。英福(fu)康(kang)真空計維(wei)修保養

當壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)膜片上(shang)未施加控(kong)制(zhi)電(dian)(dian)(dian)壓(ya)時，由于(yu)彈(dan)簧(huang)的(de)機械力作(zuo)用在(zai)壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)膜片和密封墊上(shang)，使壓(ya)電(dian)(dian)(dian)閥(fa)氣(qi)路關閉。因而，可(ke)以通過(guo)改變施加在(zai)壓(ya)電(dian)(dian)(dian)陶(tao)瓷(ci)膜片上(shang)的(de)控(kong)制(zhi)電(dian)(dian)(dian)壓(ya)的(de)大小，來改變壓(ya)電(dian)(dian)(dian)閥(fa)的(de)流(liu)導，從而改變流(liu)過(guo)壓(ya)電(dian)(dian)(dian)閥(fa)的(de)氣(qi)體(ti)流(liu)量(liang)。于(yu)是(shi)，可(ke)實現真(zhen)(zhen)空(kong)(kong)裝(zhuang)置(zhi)的(de)真(zhen)(zhen)空(kong)(kong)室(shi)中的(de)真(zhen)(zhen)空(kong)(kong)度(du)調節。英福康真(zhen)(zhen)空(kong)(kong)計維修保養(yang)
