自动排水器工作流程是什么

自动排水器由上盖、防护罩、水杯和自动排水部件组成，上盖的接口与设备或系统冷凝水流水端连接，冷凝水经过大过滤网粗滤后流入水杯。

The automatic drainer is composed of an upper cover, a protective cover, a water cup and an automatic drainer. The interface of the upper cover is connected with the water end of the condensate flow of the equipment or system, and the condensate flows into the water cup after coarse filtration through a large filter screen.

当水杯内无气压时，浮子靠自重落下，阀盖关闭内罩的上节流孔，活塞靠弹簧压下，活塞杆与O型圈脱开，冷凝水经过小滤网再次过滤后通过排水口排出，因而谓之“常开型”。

When there is no air pressure in the water cup, the float falls down by its own weight, the valve cover closes the upper orifice of the inner cover, the piston is pressed down by the spring, the piston rod is separated from the O-ring, and the condensed water is filtered again through the small filter screen and discharged through the drain, so it is called "normally open type".

当水杯内存在气体压力，并且气压大于zui低作动压力（0.15Mpa）时，活塞受气体压力作用，克服弹簧力及摩擦阻力上移。排水口道关闭

When there is gas pressure in the water cup, and the air pressure is greater than Zui low actuation pressure (0.15Mpa), the piston moves up against the spring force and friction resistance. Outfall closed

当水杯内的水位升高一定位置，浮子浮力克服自重后通过杠杆使力放大后将阀盖打开，气压力进入内罩活塞上腔，使活塞下移，排水口被打开排水。此时内罩腔内的压缩气体通过射流片的针孔形成射流喷出，加大排水口流速。故本品有排水时间段的优点。

When the water level in the water cup rises to a certain position, the buoyancy of the float overcomes its self weight, and then the valve cover is opened after the force is amplified by the lever. The air pressure enters the upper chamber of the piston in the inner cover to make the piston move down, and the water outlet is opened to drain. At this time, the compressed gas in the inner hood cavity is ejected through the pinhole of the jet sheet to increase the flow rate of the drainage outlet. Therefore, this product has the advantage of drainage time.

水位下降到一定位置，浮子所受浮力减小阀盖落下，内罩上节留孔又被关闭，活塞上腔气压通过射流片针孔排泄，活塞上移排水口再次被关闭。

When the water level drops to a certain position, the buoyancy of the float decreases, the valve cover falls down, the hole on the upper section of the inner cover is closed again, the air pressure in the upper chamber of the piston is discharged through the pinhole of the jet piece, and the piston moves up, and the drain is closed again.
