進口電動超薄型球閥 調節(jié)型電動對夾式球閥 RETZ瑞茨

RETZ瑞茨/我們一直致力于流體控制和測控領域的持續(xù)創(chuàng)新，始于2005……(對夾式)進口電動超薄型球閥的閥體比一般法蘭球閥結構短，適用于工廠同一管路閥門數(shù)量多的場合。球體具有旋轉的90度動作，球有圓形通孔通過軸線，當球旋轉90度時，在進、出口處應全部呈現(xiàn)球面，從而截斷流動，反之既呈現(xiàn)通孔，使介質通過

retz The valve body of imported electric ultra-thin ball valves (wafer type) has a shorter structure than ordinary flange ball valves, and is suitable for situations where there are many valves in the same pipeline in the factory. The sphere has a rotating 90 degree action, with a circular through-hole passing through the axis. When the sphere rotates 90 degrees, it should all present a spherical surface at the inlet and outlet, thereby cutting off flow. Conversely, it should present a through-hole, allowing the medium to pass through

用途慨述 Overview of use

(對夾式)進口電動超薄型球閥球芯通道形狀有V形及O形。主要適用于兩位切斷、調節(jié)的場合。球閥與執(zhí)行機構的連接采用直連方式，電動執(zhí)行機構內進口電動超薄型球閥2.jpg置伺服系統(tǒng)，無須另配伺服放大器，輸入4-20mA信號及220VAC電源即可控制運轉。電動對夾球閥具有連線簡單，結構緊湊、尺寸小、重量輕、阻力小、動作穩(wěn)定可靠等優(yōu)點。本閥與普通球閥相比，具有結構長度短、重量輕、安裝方便、節(jié)省材料等顯著的優(yōu)點。此外，閥座采用彈性密封結構，密封可靠，啟閉輕松。對夾球閥設有耐火結構，萬一發(fā)生火災時，仍然能夠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
