Description
Technical field
The utility model is related to engine charge technical fields, more particularly, to a kind of booster relief valve silencer.
Background technology
When automobile is when suddenly slowing down or emergency stop, engine air throttle is closed rapidly, pipeline gas between booster and air throttle
Body pressure persistently increases, and after gas flow reduces to a certain extent in compressor, just will produce surge, will cause to press when serious
Compressor wheel damages；Compressor surge can effectively be solved the problems, such as using pressure release valve technology.When air throttle suddenly closes, relief valve is beaten
It opens, the high pressure gas in compressor is bypassed in the low pressure air filter pipe before compressor, and gas flow loop is formed in pressure piping, is increased
Depressor surge problems are resolved.When air throttle is opened, relief valve is closed, and circulation loop disconnects.
But it can cause pressure release noise due to caliber change when passing through relief valve due to high pressure gas after supercharged, influence whole
Vehicle NVH.
Utility model content
In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a kind of booster relief valves to disappear
Sound device, to achieve the purpose that reduce compressor relief valve pressure release noise.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is：
The booster relief valve silencer, including pressure release valve seat and the relief valve being located on pressure release valve seat, the relief valve
It is equipped with connected channel between seat and relief valve, hush pipe is equipped in the channel between the pressure release valve seat and relief valve.
Further, the pressure release valve seat is equipped with the placing groove for placing hush pipe.
The hush pipe is metal tube.
The hush pipe is cylindrical structure, is evenly equipped with one group of gas-permeable channels thereon.
Coordinated by sealing ring between the pressure release valve seat and hush pipe one end, between relief valve and the hush pipe other end
Sealing.
The gas-permeable channels are the venthole of groove-like structure.
The installation groove of installation sealing ring is equipped on the pressure release valve seat and relief valve.
The utility model compared with prior art, has the following advantages：Booster relief valve acoustic wave filter structure design is closed
Reason, haves no need to change pipeline structure, and convenient for arrangement installation, structure can effectively reduce pneumatic noise, simple in structure, cost
It is low.

The content expressed by each width attached drawing of this specification and the label in figure are briefly described below：
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is utility model works principle schematic.
Fig. 3 is the utility model hush pipe structural schematic diagram.
In figure：
1. relief valve, 2. hush pipes, 3. sealing rings, 4. pressure release valve seats, 5. air filter pipes, 6. valve seals.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
The booster relief valve silencer, including pressure release valve seat and the relief valve that is located on pressure release valve seat, pressure release valve seat and
It is equipped with connected channel between relief valve, hush pipe is equipped in the channel between pressure release valve seat and relief valve.Have no need to change pipe
Line structure, convenient for arrangement installation, structure can effectively reduce pneumatic noise.
The concrete scheme of the utility model is described in detail below by Fig. 1 to Fig. 3.
Booster relief valve silencer, including relief valve 1, hush pipe 2, seat sealing ring 3, valve seals 6 and pressure release valve seat
4.Relief valve 1 is equipped with the installation groove of valve seals, and pressure release valve seat is equipped with the placing groove for placing hush pipe, placing groove
In be equipped with seat sealing ring installation groove.
Valve seals 6 and seat sealing ring 3 are O-ring；Valve seals install the groove into relief valve, and hush pipe and seat are close
Seal is installed in pressure release valve seat, and connecting bolt with the installation of pressure release valve seat by relief valve is fastened.
There are two sealed structures between hush pipe 2 and relief valve and pressure release valve seat counterface.First seal structures are
The counterface of hush pipe 2 and the seat sealing ring on pressure release valve seat.Seat sealing ring is rubber seal, is mounted on pressure release valve seat
On groove in, to eliminate the gap of metal tube and pressure release valve seat, prevent high pressure from generating new noise across this gap.The
Two seal structures are the valve seals counterface of hush pipe 2 and relief valve 1, and air-tight structure is the same as first of sealing above
Structure is the same.
Relief valve and pressure release valve seat tighten fixation by bolt, and hush pipe 2 is pressed to the recessed of pressure release valve seat 4 by relief valve 1
In slot.O-ring is coordinated to be sealed groove gap simultaneously.
Hush pipe 2 is metal tube；Hush pipe 2 is cylindrical structure, is evenly equipped with one group of gas-permeable channels thereon.Gas-permeable channels are equal
The multiple groove-like structures being distributed on hush pipe.The venthole of groove-like structure, size and spacing after surveying discouraged acoustic frequency by leading to
It crosses calculating to determine, and processes exemplar progress test evaluation and obtain.Metal tube meets certain roughness and verticality requirement, it is ensured that
Stationary plane is bonded metal tube with cooperation parts mounting surface up and down.
3 points of three-step process of hush tube are completed, and then assembly uses.Cutting obtains the metallic conduit of specific length first, so
Machining obtains installation base on metallic conduit afterwards, and last machine adds slot.First in the groove mounting O-shaped of pressure release valve seat when installation
Then circle installs hush pipe, then in the groove mounting O-shaped rings of relief valve, finally installs relief valve and tightens bolt.
The relief valve of the utility model can be arranged on booster, after can also being arranged in supercharger air compressor outlet
On pipeline, under both arrangements, the relief valve silencer is applicable, and the principle under both arrangements is identical.
The operation principle of the booster relief valve silencer of the utility model：As shown in Fig. 2, 1 valve of relief valve when pressure release
Open, high pressure gas from blower outlet through relief valve valve to multiple-grooved hole hush pipe, most enter air filter pipe through bypass flow channel afterwards
5.High pressure gas is divided into air-flow A, B when passing through hush tube.Air-flow A is low speed flow, and hush pipe slot is close to lower section, high pressure gas
When into hush pipe, gas flow changes greatly, and kinetic energy rejection is big, and flow velocity is low.Air-flow B is high-speed flow, and hush pipe top slot is close
Collection, when high pressure gas is through hush pipe, gas circulation is big, and kinetic energy rejection is small, and flow velocity is high.Flow through the high-speed flow B after hush pipe
Generation vortex flow-disturbing is mixed with low speed flow A, further decreases gas kinetic energy.Low Medium Frequency sound wave is stopped and is disappeared by slot simultaneously
It removes, effectively reduces airflow noise.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using the improvement of the various unsubstantialities of the design and technical solution progress of the utility model,
Or it is not improved the design of the utility model and technical solution are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
