This invention discloses a drainage mechanism for an air compressor's air tank, comprising two supports. The tops of the two supports are fixedly connected to the air tank body. A drain pipe is fixedly connected to the bottom of the outer wall of the air tank body. One end of the drain pipe is fixedly connected to a valve seat. A rotating shaft is rotatably connected to one side of the inner wall of the valve seat. A spherical baffle is fixedly connected to one end of the rotating shaft. This invention utilizes the coordinated use of a liquid level sensor, valve seat, rotating shaft, and drive assembly to avoid drainage anomalies caused by interference or false triggering of a single sensor through the coordinated judgment of two liquid level sensors. This ensures that the drainage action only starts when the accumulated water reaches a set threshold, preventing frequent start-stop cycles. Furthermore, it employs an electric telescopic rod driven by a gear-rack transmission instead of a traditional solenoid valve, resulting in high transmission accuracy, strong impact resistance, reduced risk of valve jamming or sealing failure, fast response speed, and lower maintenance costs compared to solenoid valves.

The utility model discloses building drainage riser sound insulation double -layer pipe joint, and the joint main part is tubular structure, including inner tube interface, outer tube interface and exhaust hole, wherein inner tube interface and outer tube interface set up in the both ends, exhaust hole is located in the pipe wall of joint main part, is equipped with gas hole and air inlet on exhaust hole, wherein the gas hole is vertically upward from the upper end of joint main part, and the air inlet is communicated with the gas hole and is inclined upward from the inner wall of joint main part and passes in. Inner tube interface and outer tube interface are connected with inner tube and outer tube respectively and form double -layer pipeline structure, wherein the inner tube plays the role of drainage, and the outer tube plays the role of exhaust, ensure the smooth drainage of light sound, stable and smooth. The utility model has the advantages that when the riser drainage, the air under the water flow can be smoothly discharged, and any air resistance phenomenon will not be caused, and similar to the principle of gun silencer, reduce the noise intensity and improve the drainage capacity.
