一、矿用电动闸阀价格介绍
矿用防爆电动闸阀主要用于煤矿,井下,一般这种防爆矿用电动闸阀,带煤安电动闸阀,矿用防爆电动闸阀电源电压有380V和660V,这种电动闸阀必须带有煤安证才能进矿。电动装置特点:拥有矿用证和煤安证,防爆型防护等级为IP68。适用于易燃易爆的场合,安全系数高、操作功能强、性能稳定等。防爆型产品有dI和dIIBT4两种,dI适用于煤矿非采掘工作面;dIIBT4用于工厂,适用于环境为IIA、IIB级T1~T4组的爆炸性气体混合物。本产品的性能符合JB/T8528-1997<普通型阀门电动装置技术条件>的规定。防爆型的性能符合GB3836.1-2000<爆炸性环境用防爆电气设备通用要求>及JB/T8529-1997<隔爆型阀门电动装置技术条件>的规定。并经国家防爆电气产品测试中心检定,取得了防爆合格证。整体型电装是在Z普通型基础上派生而成,增加了不少电器和电子元件,整体普通型电气部分主要由多功能模块MK1 远程控制模块MK2 按钮盒指示灯、开度表、接触器等组成。多功能模块MK1又由相位识别器XS、接触器互锁保护器HB和直流电源DC三部分组成。远程模块MK2由四个固态继电器和三个拨码开关组成。
二、矿用电动闸阀价格特点
①阀门采用压力自紧式密封或阀体、阀盖垫片密封结构,值得信赖!使用安全可靠。②阀瓣采用双闸板中间带万向顶结构,能自动调整阀瓣与阀座密封面吻合度,保证阀门的密封。同时此结构维修方便,节约费用,阀瓣互换性较好。 ③阀瓣、阀座密封面用钴铬钨硬质合金由等离子喷焊而成,密封面硬度高,耐磨擦,抗擦伤,使用寿命长。 ④阀杆用渗氮钢制成,表面氮化处理,硬度高,抗擦伤,耐腐蚀,使用寿命长。 ⑤电动装置配有转矩控制机构、现场操作机构和手、电动切换机构。除就地操作外,还可以进行远距离操作、PLC控制、4~20mA电流输入输出智能控制等。 ⑥手动阀门由手动机构或撞击时手轮开启。减小阀门操作力。 ⑦阀门可安装在管道的任何位置,同时根据介质和介质的温度选择碳钢或合金钢阀门。⑧初次安装和调试时,必须手动把阀门开到约一半的位置,以免电机相序接反导致阀门或电装损坏。
