電動插板閥使用中注意事項及其特點

電動插(cha)板閥有哪些(xie)特點(dian)，以及使用中(zhong)需(xu)要注意哪些(xie)事項？下(xia)面讓球一閥門來描述一下(xia)吧。

插板(ban)(ban)(ban)(ban)閥(fa)(fa)的(de)啟(qi)閉(bi)(bi)件是閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)，閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)的(de)運動方向(xiang)與流(liu)體方向(xiang)相垂直，插板(ban)(ban)(ban)(ban)閥(fa)(fa)只能作全開和全關，不能作調節和節流(liu)。閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)有兩(liang)個密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)，Zui常(chang)用(yong)(yong)的(de)模式(shi)閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)閥(fa)(fa)的(de)兩(liang)個密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)形成(cheng)楔形、楔形角隨閥(fa)(fa)門參(can)數而異，通常(chang)為50，楔式(shi)插板(ban)(ban)(ban)(ban)閥(fa)(fa)的(de)閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)可以(yi)做(zuo)(zuo)成(cheng)一個整(zheng)體，叫(jiao)做(zuo)(zuo)剛性閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)；也可以(yi)做(zuo)(zuo)成(cheng)能產生(sheng)微量(liang)變(bian)形的(de)閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban),以(yi)改善其工(gong)藝性，彌補密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)角度在加(jia)工(gong)過程(cheng)中產生(sheng)的(de)偏差，這(zhe)種(zhong)閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)叫(jiao)做(zuo)(zuo)彈性閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)插板(ban)(ban)(ban)(ban)閥(fa)(fa)關閉(bi)(bi)時，密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)可以(yi)只依(yi)靠(kao)介質壓(ya)力來(lai)密(mi)(mi)(mi)封(feng)(feng)，即依(yi)靠(kao)介質壓(ya)力將閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)的(de)密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)壓(ya)向(xiang)另一側的(de)閥(fa)(fa)座來(lai)保(bao)(bao)證密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)的(de)密(mi)(mi)(mi)封(feng)(feng)，這(zhe)就(jiu)是自密(mi)(mi)(mi)封(feng)(feng)。大部分插板(ban)(ban)(ban)(ban)閥(fa)(fa)是采用(yong)(yong)強制密(mi)(mi)(mi)封(feng)(feng)的(de)，即閥(fa)(fa)門關閉(bi)(bi)時，要依(yi)靠(kao)外力強行將閘(zha)(zha)(zha)板(ban)(ban)(ban)(ban)壓(ya)向(xiang)閥(fa)(fa)座，以(yi)保(bao)(bao)證密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)的(de)密(mi)(mi)(mi)封(feng)(feng)性。插板(ban)(ban)(ban)(ban)閥(fa)(fa)密(mi)(mi)(mi)封(feng)(feng)結(jie)構可以(yi)分軟密(mi)(mi)(mi)封(feng)(feng)、硬密(mi)(mi)(mi)封(feng)(feng)結(jie)構。
