一、H72TC陶瓷对夹式止回阀简介
         H72TC陶瓷对夹式止回阀又称陶瓷单向阀或陶瓷逆止阀，其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。 启闭件靠介质流动和力量自行开启或关闭，以防止介质倒流的阀门叫陶瓷止回阀。
二、用途：
该系列阀门使用于电厂干灰系统仓泵的进出料门，也可用于矿山、化工等各类有磨损的干灰、水渣等介质管道的止回装置。
本阀门闭后任何方向全部密封。阀体阀盖采用WCB铸钢件或不锈钢铸件。密封面采用硬密封件。
本阀料口耐磨性能强，密封性能好，启动负荷小，卡灰及结灰现象少。
本阀采用高档增韧结构陶瓷密封，机械强度高，耐磨性能好，使用寿命长。结构紧凑可任意角度安装。
三、特点：
阀辨与阀座均采用高性能结构增韧陶瓷制造。
该品为手行式闸板结构。密封可靠、启闭轻便、维修方便。
本品具有高耐磨、耐冲刷等特点。
适用于水管道安装。
四、主要参数：
公称压力：1.0MPa-1.6MPa
公称通经：DN15-DN1500
适用温度：-40°C+797°F
连接形式：对夹式
