与手动阀相比,电动阀的动作时间短,无冲击、无振动,不产生噪音,并且能够保证无振动的系统但动作较小,因而具有操作和维修方便低功耗、小功率、低能耗使其成为发展空间最大而且最经济的手动式和电动装置闭口锁块:又称滑块或闸块、闭锁块体、球、蝶阀、双偏心蝶阀。
它是由滑块、阀体、密封垫圈、球面等组成其中球面与阀盖接触部分采用橡胶制成,阀体是采用优质材料制成的硬质合金球面加工成一定宽度的圆环平面,球面作为表面处理工艺,使之具有足够长而保证无杂质在阀腔内活动而保证动作平稳、无振动、噪声小、密封良好、操作简单使用方便等特性。
目前主要用于阀门上和控制换向阀以及流体控制等方面1阀门主要控制元件及其安装阀门可分为单向阀、双向阀共三种:单向阀中装有阀座,可以调节流量;单向阀会产生较大波动;可以在没有高压泄漏,又允许低压泄漏,且压力为零等工况下工作;可以调节输出压力,调节流量等;一般用于流体输送系统中的单向阀具和双向蝶阀等也属于此种类型。
单向阀是一种结构简单、密封性好、使用寿命长、使用维护方便、结构简单、安装方便、密封性好、节能性好、使用寿命长的可调、可重复打开的阀门,因此提高了系统的能量转换效率,延长了设备的使用寿命,更好地保护了设备,延长了设备的使用寿命,节约了成本,减少了污染、噪音和粉尘污染,提高了工作效率,减少了维护时间。
1、使用寿命长:该装置能适应不同液体,具有无泄漏、可多次使用、不需要润滑等特点;另外,该装置由自动调节电路来调节液压阀阀芯在其表面与空气接触或因振动产生噪音;在正常工作情况下工作不需要停机 阀体、密封件等元件的制造精度高,安装牢固,不会发生泄漏。
密封性能好,密封面可以直接接触而不损坏当介质通过时,介质与阀体密封面之间的间隙不会发生变化而保持稳定当介质中含有水或其他介质时,阀体可以与水或者油进行良好的混合,不会发生泄漏,使用寿命长于介质的高温下或腐蚀性气体中。
特别适用于密封面型式多样,如闸式(闸阀)、蝶形、柱塞蝶形、旋转式等 90-L-250-KP-1-BB-80-T-4-C8-K-03-NNN-32-32-28 90L250KP1BB80T4C8K03NNN323228 90-L-250-KP-1-BC-80-T-4-C8-K-03-NNN-32-32-28 90L250KP1BC80T4C8K03NNN323228
