用途 User

該閥是作為管路的啟閉設(shè)備使用的，由一小電磁閥控制主閥的開(kāi)關(guān)，可實(shí)現(xiàn)遠(yuǎn)程和就地控制。

The valve is used as the opening and closing equipment of the pipeline, which controls the switch of the main valve by a small solenoid valve and can realize remote and local control.

特點(diǎn) Characteristic

安裝使用方便，控制部分無(wú)復(fù)雜的電傳動(dòng)機(jī)構(gòu)，不易出故障，設(shè)定簡(jiǎn)單。與傳統(tǒng)閥門比較有體積小，重量輕，功率小，維修簡(jiǎn)單，使用方便，安全可靠的優(yōu)點(diǎn)。

It is easy to install and easy to use. The control part has no complicated electric transmission mechanism. Compared with the traditional valve, it has the advantages of small volume, light weight, small power, simple maintenance, easy to use and safe and reliable.

原理 Principle

導(dǎo)閥為一電磁閥，當(dāng)電磁閥打開(kāi)時(shí)，膜片上腔壓力減小，主閥打開(kāi)。電磁閥關(guān)閉，主閥也關(guān)閉。電磁閥分常開(kāi)、常閉兩種。正常供貨狀態(tài)為常閉電磁閥。也可配置防爆型電磁閥。

The pilot valve is a solenoid valve. When the solenoid valve is opened, the cavity pressure decreases and the main valve opens. The solenoid valve is closed and the main valve is closed. Solenoid valve is normally open and closed. Normal supply status is normally closed solenoid valve. Explosion-proof solenoid valve can also be configured.
