Abstract
The utility model relates to an inner valve vehicle vent pipe which comprises a shell body and a valve assembling body, wherein an air inlet is formed at one end of the shell body, and an air outlet is formed at the other end of the shell body. An air inlet pipe and a vent pipe are arranged inside the shell body, two ends of the air inlet pipe are connected with the air inlet and the air outlet, two ends of the vent pipe are connected with the air inlet and the air outlet, at least two through holes are formed in the surface of the air inlet pipe, and at least two through holes are formed in the surface of the vent pipe. The valve assembling body is arranged between the air inlet pipe and the vent pipe and is formed by an annular partition board which is in a right square bracket shape and a valve body fixed on the inner side of the partition board. A flow choking turnable plate is arranged on an inner ring of the valve assembling body, the flow choking turnable plate is connected with one end of a valve rod, and the other end of the valve rod stretches out of the shell body. The partition board is provided with an adjustable piston-type overpressure bypass valve, the valve assembling body divides the interior of the shell body into an air inlet cavity containing the air inlet pipe and a venting cavity containing the vent pipe, and an S-shaped pipeline penetrating through the partition board from the air inlet cavity to the vent cavity is arranged in the shell body. The inner valve vehicle vent pipe has the advantages of being capable of adjusting exhaust resistance in an omnibearing mode and meeting the user requirements for vent sounds.
Description
Technical field
The utility model relates to a kind of motor vehicle exhaust device, particularly interior valve automobile exhaust pipe.
Background technique
Automobile is when operation, and the user needs automobile to send larger sound equipment sometimes increases Driving, sometimes needs automobile in mute state, to keep quite.But current used automobile and common exhaust duct are difficult to reach this effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can comprehensive adjusting exhaust resistance, can meet the interior valve automobile exhaust pipe of user to the exhaust sound demand.
To achieve these goals, the utility model has been taked following technical approach.
In the utility model, the valve automobile exhaust pipe comprises that two ends are provided with the housing of suction port and relief opening, be provided with in described housing that two ends are connected with relief opening with described suction port respectively, surface is with suction tude and the outlet pipe of at least two through holes, and be arranged between described suction tude and outlet pipe, by annular
?shape dividing plate and the valve sets zoarium that is fixed on the valve body formation on described dividing plate inboard.In described valve sets zoarium, ring is provided with the choked flow turnover panel, described choked flow turnover panel is connected with an end of valve rod, the described valve rod the other end stretches out housing, described valve sets zoarium will be divided into the air inlet chamber that contains suction tude and the exhaust chamber of containing outlet pipe in housing, be provided with in housing and arrive the S shape pipeline of exhaust chamber from the air inlet chamber through described dividing plate.
Described valve body is provided with choked flow turnover panel position-limited lever.
Described dividing plate is provided with the overvoltage bypass valve.
One end of described housing is provided with corresponding to the overvoltage bypass valve, with the adjustment hole of screw.
The utility model adopts said structure, can comprehensive adjusting exhaust resistance, and make motor there is good power performance.Simultaneously, the user can open and close and the cracking pressure of piston type bypass valve by switch valve, regulates drag size, thereby regulates the exhaust sound size, and then meets the demand of user to the different acoustic size.
The accompanying drawing explanation
Fig. 1 is the structural representation of valve automobile exhaust pipe in the utility model.
Embodiment
As shown in Figure 1, valve automobile exhaust pipe in the utility model, comprise that two ends are provided with the housing 2 of suction port 1 and relief opening 13, be provided with in described housing 2 that two ends are connected with relief opening 13 with described suction port 1 respectively, surface is all with suction tude 18 and the outlet pipe 14 of at least two through holes 17, and be arranged between described suction tude 18 and outlet pipe 14, by annular
? shape dividing plate 5 and the valve sets zoarium that is fixed on valve body 8 formations on described dividing plate 5 inboards, in described valve sets zoarium, ring is provided with choked flow turnover panel 11, described choked flow turnover panel 11 is connected with an end of valve rod 9, the other end of described valve rod 9 stretches out housing 2, by external pneumatic or electric twisting device actuate valve stem 9, described valve sets zoarium will be divided into the air inlet chamber 4 that contains suction tude 18 and the exhaust chamber 16 of containing outlet pipe 14 in housing 2, be provided with in housing 2 and arrive the S shape pipeline 3 of exhaust chamber 16 from air inlet chamber 4 through described dividing plate 5.Described valve body 8 is provided with choked flow turnover panel position-limited lever 15.Described dividing plate 5 is provided with overvoltage bypass valve 10.Described overvoltage bypass valve 10 by T-shaped support, be vertically fixed on the front and back piston type valve block 6 on described T-shaped rack cross-bar and be set on T-shaped rack cross-bar and be folded in before and after spring 7 between valve block 6 form.One end of described housing 2 is provided with corresponding to overvoltage bypass valve 10, with the adjustment hole 19 of screw 12.
Working principle is:
When the choked flow turnover panel 11 by valve rod 9 throttle down assemblying bodys, exhaust airstream enters from suction port 1, by suction tude 18 through holes 17, is entered in air inlet chamber 4, through S shape pipeline, to exhaust chamber 16, enters outlet pipe 14 by the outlet pipe through hole and discharges.During exhaust airstream process S shape pipeline, thereby because can making air-flow collide, multiple bend pipe subdues the exhaust resonant that the exhaust energy reduction is brought by exhaust energy, add two chambers and make the exhaust energy of gas expansion diffusion reduction reduce better resonant, thereby reach muting function.Can produce larger resistance during gas process S shape pipeline, when the high rotating speed resistance of motor surpasses restriction, during overpressure, gas can back down piston type bypass valve 10, and too high exhaust gas directly is put into to exhaust chamber 16 from air inlet chamber 4.Described piston type bypass valve 10 applicable to all by resistance in the outlet pipe with dividing plate.When the choked flow turnover panel 11 of valve sets zoarium is opened, exhaust airstream enters suction tude 18 from suction port 1, through valve body 8, after outlet pipe 14, discharges relief opening 13, at this moment, due to gas, directly by housing, can not reduce exhaust energy, thereby reach the resonant effect.
