Abstract
The utility model discloses an automobile engine silencer drainage arrangement which comprises a silencer body, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are arranged on the silencer body; a water discharge pipe of which one end is close to the bottom part of the silencer body is arranged in the silencer body, and the other end of the water discharge pipe extends to the air outlet end of the air outlet pipe. By using the fluid mechanics principle in the utility model in the flowing process of exhaust gas of an engine, the cross-sectional area of a silencer is big, and the flow speed of the exhaust gas is slow; the cross-sectional area of the air outlet pipe is small, and flow speed of the exhaust gas is fast; a water inlet of the water discharge pipe is arranged in the silencer, and a water outlet is arranged in the air outlet pipe. According to the hydromechanical suction effect, the pressure of the water inlet of the water discharge pipe is higher than that of the water outlet, therefore accumulated water of the internal part of silencer is discharged outside. The utility model has the advantages of simple structure and low cost. Besides, the utility model reduces the corrosion effect which is formed by the method that the accumulated water acts on the silencer and the service life is prolonged.
Description
Technical field
The utility model relates to the discharger of the inner ponding of a kind of motor silencer.
Background technique
Present motor car engine baffler, after engine start, owing to the waste gas of discharging meet cold condense into moisture or when cleaning the priming charge branch, easily remain in the baffler.Though a part of ponding can discharge or evaporate with the waste gas of discharging, and is generally not thorough.Especially short time operation, water is stayed in the baffler and is easily got rusty, and has quickened the damage of baffler.From investigation, the damage of most bafflers all is because inner ponding makes due to it gets rusty.
Summary of the invention
Technical problem to be solved in the utility model provides the Automobile Engine Sound Arrester Drainage Means that a kind of moisture that will remain in the baffler is in time discharged.
For achieving the above object, the technical solution of the utility model is: Automobile Engine Sound Arrester Drainage Means comprises the baffler body, be installed on suction tude and outlet pipe on the baffler body, the waste pipe of one end near baffler body bottom is installed in the described baffler body, and the other end of waste pipe extends to the outlet side of outlet pipe.
Owing to adopt technique scheme, Automobile Engine Sound Arrester Drainage Means comprises the baffler body, be installed on suction tude and outlet pipe on the baffler body, the waste pipe of one end near baffler body bottom is installed in the described baffler body, and the other end of waste pipe extends to the outlet side of outlet pipe; The utility model utilizes fluid mechanics principle, and the waste gas of motor is in process of flowing, and the sectional area of baffler is big, and the waste gas flow velocity is slow; The sectional area of outlet pipe is little, and the waste gas flow velocity is fast.And the waste pipe water intake is in baffler inside, and water outlet is in outlet pipe inside, and according to hydromechanical suction effect, the pressure of waste pipe water intake is higher than the pressure of water outlet, so the ponding of baffler inside just is discharged from.The utility model has alleviated because of the corrosive action of ponding to baffler, prolonged the working life of baffler, and it is simple in structure, with low cost, effect is obvious.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, Automobile Engine Sound Arrester Drainage Means comprises baffler body 2, be installed on suction tude 1 and outlet pipe 3 on the baffler body 2, the waste pipe 4 of one end near baffler body bottom is installed in the described baffler body 2, and the other end of waste pipe 4 extends to the outlet side of outlet pipe 3.
Methods such as welding of waste pipe 4 usefulness or screw are fixing and baffler body 2 and outlet pipe 3 are fixed together.Its working principle is: the waste gas of motor is in process of flowing, and the sectional area of baffler inside is big, and the waste gas flow velocity is slow; The sectional area of outlet pipe 3 is little, and the waste gas flow velocity is fast.And the water intake of waste pipe 4 is in baffler body 2 inside, and water outlet according to hydromechanical suction effect, forms pressure difference between the water intake of waste pipe 4 and the water outlet in outlet pipe 3 inside.Simultaneously, the waste gas of motor enters baffler, and the pressure in the baffler 2 will be higher than atmospheric pressure, and this just makes the pressure difference at water intake and drain opening place further increase.Thereby, make the ponding of baffler inside very easily discharge.
Claims (2)
1, Automobile Engine Sound Arrester Drainage Means, comprise baffler body (2), be installed on suction tude (1) and outlet pipe (3) on the baffler body (2), it is characterized in that: the waste pipe (4) of an end near baffler body bottom is installed in the described baffler body (2), and the other end of waste pipe (4) extends to the outlet side of outlet pipe (3).
2, Automobile Engine Sound Arrester Drainage Means according to claim 1 is characterized in that: described waste pipe (4) is fixed together with the fixing method of welding or screw and baffler body (2) and outlet pipe (3).
