閥門電動裝置的組成

電動(dong)(dong)(dong)(dong)(dong)(dong)裝置(zhi)一般由下列部(bu)分組成(cheng)：電動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)減速(su)機(ji)(ji)構(gou)，用以降(jiang)低(di)電動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)(de)輸出轉(zhuan)(zhuan)速(su)；行程(cheng)控制機(ji)(ji)構(gou)，用以調節(jie)和準(zhun)確(que)控制閥(fa)門(men)的(de)(de)(de)(de)啟(qi)閉(bi)位(wei)置(zhi)；轉(zhuan)(zhuan)矩限(xian)制機(ji)(ji)構(gou)，用以調節(jie)轉(zhuan)(zhuan)矩（或推力）并使(shi)之不超過預(yu)定(ding)值(zhi)；手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)(dong)、電動(dong)(dong)(dong)(dong)(dong)(dong)切換機(ji)(ji)構(gou)，進行手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)(dong)或電動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作的(de)(de)(de)(de)聯鎖機(ji)(ji)構(gou)；開(kai)度指示(shi)器，電動(dong)(dong)(dong)(dong)(dong)(dong)閥(fa)門(men)，用以顯(xian)示(shi)閥(fa)門(men)在啟(qi)閉(bi)過程(cheng)中所處的(de)(de)(de)(de)位(wei)置(zhi)。其中，行程(cheng)控制機(ji)(ji)構(gou)、轉(zhuan)(zhuan)矩限(xian)制機(ji)(ji)構(gou)、手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)(dong)、電動(dong)(dong)(dong)(dong)(dong)(dong)切換機(ji)(ji)構(gou)及開(kai)度指示(shi)器等合(he)稱為(wei)電動(dong)(dong)(dong)(dong)(dong)(dong)執(zhi)行器。

不銹鋼(gang)電動閥門的優點(dian)

1、不銹鋼(gang)電動(dong)(dong)閥門在(zai)接(jie)受信(xin)號的速度敏捷(jie)，輸(shu)出(chu)直(zhi)線位移(加電/氣轉(zhuan)換裝置(zhi)后，電動(dong)(dong)閥門生產廠家，也可以接(jie)受連續(xu)的電信(xin)號)，有的配(pei)上搖(yao)臂后，可輸(shu)出(chu)角(jiao)位移。

有正、反作用(yong)功能，使用(yong)在電動(dong)閥門(men)的(de)轉移中得到(dao)一定的(de)用(yong)處。

2、不(bu)銹鋼電動閥門移動速度大，但負載增加時速度會變慢，輸出力與操作壓力有(you)關。

3、不(bu)銹鋼電動閥(fa)門可(ke)性高，但(dan)氣(qi)源中斷后閥(fa)門不(bu)能保(bao)持(chi)(加保(bao)位(wei)閥(fa)后可(ke)以保(bao)持(chi))。

4、不銹鋼電動(dong)閥門不便實(shi)現(xian)分段控(kong)制(zhi)和程序控(kong)制(zhi)，檢(jian)修維(wei)護簡單，對環境(jing)的適應性好。

5、不銹鋼電動閥門輸(shu)出功(gong)率較大，具有防爆(bao)功(gong)能，在運行時也得到了(le)安全。
