Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a drainage mechanism for a venting module of an air compression system. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The vent valve on the air compressor is also called an anti-surge valve. The vent valve on the machine can be manual or automatic. Its function is to relieve pressure and vent air when the unit is just started and the outlet valve is not open, or to relieve part of the pressure when the pressure is too high during the operation of the machine to prevent the machine from surging due to high pressure difference and small flow.

[0003] Patent announcement number CN209244805U discloses an automatically opened normally closed vent valve for an air compressor, comprising a valve body, a left connecting piece and a right connecting piece are fixedly installed on both sides of the valve body, an exhaust piece is fixedly installed on the upper end of the valve body, the left connecting piece and the right connecting piece are both connected to the valve body, a plurality of first exhaust holes are opened through the outer wall and the inner cavity of the exhaust piece, and the plurality of first exhaust holes are equidistantly distributed on half of the outer wall of the exhaust piece, a slideway is provided in the inner cavity of the left connecting piece and the right connecting piece, and the two slideways are connected to the inner cavity of the valve body, a fixed block is fixedly installed on the bottom plate of the inner cavity of the valve body, a rotating plate is provided in the valve body, a first connecting rod is fixedly connected to the middle part of the lower end of the rotating plate, the lower end of the first connecting rod is inserted into the fixed block, and a second connecting rod is fixedly connected to the middle part of the upper end of the rotating plate. The utility model is an automatically opened normally closed vent valve for an air compressor, the automatically opened normally closed vent valve for an air compressor adopts a double air inlet hole, and a double push rod rotates to exhaust air, and has good venting strength.

[0004] Although the prior art CN209244805U has many benefits during use, it still has the following problems: it lacks a protective structure for the valve core. Liquid accumulates inside the vent valve, which causes the liquid to corrode the valve core, causing the valve core to rust and affecting the smoothness of the rotation of the valve plate. Utility Model Content

[0005] The utility model aims to provide a drainage mechanism for a venting module of an air compression system to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage mechanism of a vent module of an air compression system, comprising a pipeline body, a support plate, a fixed plate and a connecting rod, a vent valve body is arranged inside the pipeline body, a support plate is installed on one side of the inner wall of the pipeline body, a connecting rod is movably installed inside the support plate, and a baffle is installed on the outer wall of one end of the connecting rod.

[0007] When using a drainage mechanism of an air compressor system venting module in the technical solution, the vent valve body controls the rotation of the valve plate. During the discharge process, the pressure of the medium delivery overcomes the spring force, causing the baffle to break contact with the fixed plate, thereby allowing the medium to flow inside the pipeline body, thereby cooperating with an external power pump and the pipeline body to exhaust or drain air. After the baffle is reset by the spring, one side of the inner wall of the pipeline body is blocked to prevent the medium from contacting the valve plate or the vent valve body, and the medium accumulated on one side of the fixed plate can be discharged through the drain pipe.

[0008] Preferably, connecting pipes are inserted and installed on the outer walls of both ends of the pipeline body, and a flange body is arranged on the outer wall of one side of the connecting pipe. The pipeline body is connected to an external device through the connecting pipe and the flange body.

[0009] Preferably, a valve plate is provided on an outer wall of one side of the vent valve body, and the valve plate is located inside the pipeline body. The vent valve body controls the valve plate to rotate in a circle, thereby controlling the on-off of the inside of the pipeline body.

[0010] Preferably, a fixing plate is installed on one side of the inner wall of the pipeline body, and the interior of the fixing plate is hollow, so that the medium can flow inside the pipeline body through the fixing plate.

[0011] Preferably, a sewage pipe is inserted and installed on one side of the lower end of the inner wall of the pipeline body, and the sewage pipe is connected to the inside of the pipeline body. The medium accumulated in the pipeline body is discharged through the sewage pipe.

[0012] Preferably, a sealing gasket is fixedly attached to the outer wall of one side of the baffle, and the sealing gasket is in contact with the outer wall of the fixing plate. The sealing gasket ensures the sealing between the baffle and the fixing plate.

[0013] Preferably, a spring is provided on the outer wall of one side of the connecting rod, and the outer wall of one end of the connecting rod is elastically connected to the support plate through the spring. The spring force ensures the relative stability of the connecting rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of protecting the valve body by arranging a baffle, a drain pipe and a spring; the vent valve body controls the rotation of the valve plate; during the discharge process, the pressure of the medium delivery overcomes the spring elastic force, causing the baffle to disengage from the fixed plate, thereby allowing the medium to flow inside the pipeline body, thereby cooperating with the external power pump and the pipeline body to exhaust or drain air; after the baffle is reset by the spring, one side of the inner wall of the pipeline body is blocked to prevent the medium from contacting the valve plate or the vent valve body, thereby achieving the purpose of protecting the valve plate and the vent valve body; and the medium accumulated on one side of the fixed plate can be discharged through the drain pipe to avoid medium accumulation.
