一、概述Outline
DJ(D/S)D型精小型氣動調節(jié)(切斷)蝶閥是由氣動活塞式執(zhí)行機構和硬(軟)密封蝶閥組成，屬旋轉型調節(jié)或切斷蝶閥。QJD(S)D型為軟密封蝶閥，QJD(S)DY型為硬密封蝶閥。
氣動蝶閥以壓縮空氣為動力源，借助電氣閥門定位器(或電磁閥)對閥門實現連續(xù)調節(jié)(或位式控制)。
該產品閥座為浮動式，具有自動對準中心的功能，閥板為圓錐形，雙向偏心安裝。閥門關閉時，閥板帶動閥座運動，達到*佳密封。閥門開啟時，立即脫開接觸，有效防止閥座磨損。
氣動執(zhí)行器機構采用可靠高效的新型AGT系列雙活塞執(zhí)行機構，能為閥門提供可靠的力矩，使閥門能按控制要求達到規(guī)定位置。
該產品具有結構輕巧簡單，流量系數大，操作使用方便，壽命長等優(yōu)點，廣泛應用于各行業(yè)的自動控制系統(tǒng)中做調節(jié)或位式控制。
DJ (D / S) D-type fine small pneumatic control (off) valve is a pneumatic piston actuator and a hard (soft) seal butterfly valve, is a spin off valve or regulator. QJD (S) D-type soft sealing butterfly valve, QJD (S) DY-type for the hard seal butterfly valve.
Pneumatic valve with compressed air as power source, with electric positioner (or solenoid valve) to achieve a continuous adjustment of the valve (or bit control).
The product is floating seat with automatic centering function, the valve plate is conical, two-way eccentric installation. Valve is closed, the valve plate driving seat movement, to achieve the best seal. Valve is turned on, immediately torn off contact, to effectively prevent valve seat wear.
Pneumatic actuator body using a new reliable and efficient AGT series dual piston actuator, the valve can provide a reliable torque, the valve can control requirements according to the required position.
The product is lightweight and simple in structure, flow coefficient, easy operation, long life, etc., are widely used in various industries to do the automatic control system adjust or position control.
