用途慨述 Overview of use

(对夹式)进口电动超薄型球阀球芯通道形状有V形及O形。主要适用于两位切断、调节的场合。球阀与执行机构的连接采用直连方式，电动执行机构内置伺服系统，无须另配伺服放大器，输入4-20mA信号及220VAC电源即可控制运转。电动对夹球阀具有连线简单，结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。本阀与普通球阀相比，具有结构长度短、重量轻、安装方便、节省材料等显著的优点。此外，阀座采用弹性密封结构，密封可靠，启闭轻松。对夹球阀设有耐火结构，万一发生火灾时，仍然能够可靠操作并具有良好的密封性 retz (wafer type) imported electric ultra-thin ball valve has rectangular, V-shaped and O-shaped channel shapes. It is mainly applicable to two-position cut-off and adjustment occasions. The connection between the ball valve and the actuator adopts the direct connection mode. The electric actuator has a built-in servo system. It does not need to be equipped with a servo amplifier. The operation can be controlled by inputting 4-20mA signal and 220VAC power supply. Electric wafer ball valve has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc. Compared with ordinary ball valve, this valve has the advantages of short structure length, light weight, convenient installation, and material saving. In addition, the valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The double-clip ball valve is equipped with fire-resistant structure, which can still be operated reliably and has good sealing performance in case of fire
