产品详情
一、概述Outline
DJ（D/S）D型精小型气动调节（切断）蝶阀是由气动活塞式执行机构和硬（软）密封蝶阀组成，属旋转型调节或切断蝶阀。QJD（S）D型为软密封蝶阀，QJD（S）DY型为硬密封蝶阀。
气动蝶阀以压缩空气为动力源，借助电气阀门定位器（或电磁阀）对阀门实现连续调节（或位式控制）。
该产品阀座为浮动式，具有自动对准中心的功能，阀板为圆锥形，双向偏心安装。阀门关闭时，阀板带动阀座运动，达到*密封。阀门开启时，立即脱开接触，有效防止阀座磨损。
气动执行器机构采用可靠高效的新型AGT系列双活塞执行机构，能为阀门提供可靠的力矩，使阀门能按控制要求达到规定位置。
该产品具有结构轻巧简单，流量系数大，操作使用方便，寿命长等优点，广泛应用于各行业的自动控制系统中做调节或位式控制。
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, immediay 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.
