Description

Automatic draining device with manual drainage function

[0001] The present invention relates to a drainer, and more particularly to an automatic draining device having a manual drain function for discharging a separated liquid from a gas line.

Background technique

[0002] Now the automatic drainage device with manual drainage function on the market, as shown in Figure 1, when the air pressure in the water cup a is constant, the right end of the piston b is subjected to the gas pressure and the spring force, and the body c is in contact with the body to achieve sealing. When the button d is pressed, the piston b moves to the right, and the piston b and the body c are separated to achieve the function of manual drainage. In this configuration, the button d overcomes the resistance of the diaphragm assembly e, the spring force, and the piston air pressure of about 50 N (assuming the pressure inside the cup is 0.7 MPa), and the required force is large.

[0003] Chinese Patent Licensing Publication No. CN201049270Y discloses a pneumatic automatic drain valve, which is fixed on a float with a fixed seat with a connecting rod, and the float is matched with the support by a gasket mounted on the connecting rod, and the connecting belt in the supporting seat is reset. The spring, the Y-ring piston, the piston and the water release seat with the nut, the sealing cover, the rectangular ring, the cup, the support seat and the water discharge seat are fixedly connected integrally, the upper surface of the piston is connected with a sealing ring, the lower surface A screw with a nut is attached, and the float and the support seat have an opening that engages with the link. The screw of the pneumatic automatic drainer is connected to the piston, and the piston moves with the movement of the screw. When the air pressure in the water cup is constant, the lower part of the piston is subjected to the air pressure, and the spring force and the friction resistance of the Y-ring are moved upward, and the piston is sealed with the 0 type. The ring is sealed and the drain is closed. If the screw is pulled down, the piston will move down with the screw, and the piston and the 0-ring will be opened to drain. In this structure, the screw must overcome the gas pressure of the piston and the frictional resistance of the Y-ring is about 150N (assuming the pressure in the cup is 0.7 MPa), the required force is too large, affecting the life of the piston, and the operation of the personnel is also The difficulty is increased. In addition, the water outlet cannot be equipped with joints and pipes, and the water in the water cup is directly discharged, which pollutes the surrounding environment.
