延时自闭阀的全称为可调式延时自闭冲洗阀,是既可以调节冲洗时间、控制冲洗水量大小,又能自动关闭的阀门。此种阀门的公称直径有20mm和25mm两种,安装方式有直式、角式两种。它是利用给水管内的水压,凭借内部结构造成的压差启闭的,属于压差式阀门。它可以根据安装现场的水压来调节延时长短,也可以调整螺栓以控制冲洗水量,达到节水的目的。延时自闭冲洗阀的使用参数如下。
The full-time delay self-closing valve is called an adjustable delay self-closing flushing valve, which is a valve that can adjust the flushing time, control the amount of flushing water, and can automatically close. The nominal diameter of this kind of valve has two kinds of 20mm and 25mm, there are two kinds of installation methods: straight type, angle type. It uses the water pressure in the water supply pipe and opens and closes due to the pressure difference caused by the internal structure. It belongs to differential pressure valves. It can adjust the delay time according to the water pressure at the installation site, and can also adjust the bolts to control the amount of flushing water to achieve the purpose of saving water. Delayed self-closing flushing valve use parameters are as follows.
