The valve seat shell 10 is of a tubular structure, the air release pipe 20 is arranged in the valve seat shell 10, the outer wall of the first end of the air release pipe 20 is connected with the inner wall of the valve seat shell 10 through the sealing cover 21, the outer wall of the second end of the air release pipe 20 is connected with the inner wall of the valve seat shell 10 in a sealing mode, and the valve seat shell 10, the air release pipe 20 and the sealing cover 21 form the accommodating cavity 11. The sealing cover 21 is provided with an opening 211, and the accommodating cavity 11 is communicated with the external space of the accommodating cavity 11 through the opening 211. The accommodating cavity 11 comprises a first cavity 111 and a second cavity 112, the first cavity 111 is a cavity close to the first end of the air leakage pipe 20, the first cavity 111 is a cavity close to the second end of the air leakage pipe 20, the silencing core 30 is arranged in the first cavity 111, an exhaust hole is formed in the cavity wall of the second cavity 112, and the exhaust hole is located on the valve seat shell 10.

In the embodiment of the present application, since the air bleed 20 is disposed in the valve seat housing 10, the first end of the air bleed 20 is connected with the inner wall of the valve seat housing 10 through the sealing cover 21, and the second end of the air bleed 20 is sealingly connected with the inner wall of the valve seat housing 10, the air bleed 20, and the sealing cover 21 may form the accommodation chamber 11. Since the sealing cover 21 is provided with the opening 211, the accommodating chamber 11 can communicate with the external space of the accommodating chamber 11 through the opening 211. Because the accommodating chamber 11 includes the first chamber 111 and the second chamber 112, the silencing core 30 is disposed in the first chamber 111, the exhaust hole is opened on the chamber wall of the second chamber 112, and the exhaust hole is located on the valve seat housing 10, therefore, when the relief valve seat is mounted on the intercooler air outlet pipe body 100 and the relief valve is connected with the relief valve seat, when the relief valve is opened, the gas in the intercooler air outlet pipe can flow into the relief pipe 20 and flow from the second end to the first end of the relief pipe 20, finally flows into the first chamber 111 from the opening 211 on the sealing cover 21, the gas is silenced by the silencing core 30, then flows into the second chamber 112, and is exhausted from the exhaust hole on the valve seat housing 10, so that the relief valve seat has the functions of exhausting and silencing, and the venting sound of the turbocharger can be well eliminated. That is, in the embodiment of the application, by arranging the air release pipe 20 in the valve seat housing 10, and sealing the two ends of the air release pipe 20 with the inner wall of the valve seat housing 10, arranging the silencing core 30 in the cavity formed by the valve seat housing 10, the air release pipe 20 and the sealing cover 21, opening the opening 211 on the sealing cover 21, and opening the exhaust hole on the valve seat housing 10, the air release valve seat has the functions of exhausting and silencing, so that the air release of the turbocharger can be well eliminated, and the noise level of the vehicle is improved.

In addition, in the embodiment of the present application, as shown in fig. 5, the silencing core 30 may have a tubular structure, and at least one second through hole is formed on the wall of the silencing core 30.

When the silencing core 30 is of a tubular structure and at least one second through hole is formed in the pipe wall of the silencing core 30, when gas enters the first cavity 111 through the opening 211 in the sealing cover 21, gas flows into the silencing core 30 from the first end of the silencing core 30 into the second end, and gas flows out of the silencing core 30 from the second through hole in the pipe wall of the silencing core 30, so that the gas flows more, and when the gas flows into the silencing core 30 after being discharged by the turbocharger, the energy of the gas is attenuated more, and the sound of the gas is reduced.

In this embodiment, the number of the second through holes on the silencing core 30 may be set according to actual needs, for example, may be set according to the frequency of the gas, and for example, the number of the second through holes may be 5, and the number of the second through holes is not limited herein. In addition, in the embodiment of the present application, the shape of the second through hole may be set according to actual needs, for example, the second through hole may be a circular hole or a square hole, and the shape of the second through hole is not limited herein. The wall thickness of the sound deadening core 30 may be set according to actual needs, for example, the wall thickness of the sound deadening core 30 may be 5 mm, and the value of the wall thickness of the sound deadening core 30 is not limited herein.

In addition, in the present embodiment, as shown in fig. 1, the first end of the valve seat housing 10 may be provided with a connection flange 12. When the first end of the valve seat housing 10 is provided with the connection flange 12, the relief valve may be directly connected with the connection flange 12 when the relief valve is connected with the valve seat housing 10, thereby facilitating the connection of the relief valve with the valve seat housing 10. That is, by providing the connection flange 12 at the first end of the valve seat housing 10, the connection of the relief valve to the valve seat housing 10 can be facilitated.

It should be noted that, in the embodiment of the present application, the pressure relief valve may be an electromagnetic valve, and specific reference may be made to a structure of the pressure relief valve in the related art, which is not described herein again.

Additionally, in some embodiments, the number of sound attenuating cores 30 is at least one and the number of openings 211 is at least one. The sound deadening core 30 corresponds to the opening 211.

When the relief valve seat is applied to the intercooler air outlet pipe body 100 and the relief valve seat is connected with the air release valve, when the air release valve is opened, the air in the intercooler air outlet pipe body 100 flows into the air release pipe 20, and then flows to the sealing cover 21. Since the number of the silencing cores 30 is at least one and the number of the openings 211 is at least one, the silencing cores 30 correspond to the openings 211, and therefore, when gas flows into the first cavity 111 through the openings 211 on the sealing cover 21, the gas can flow into the silencing cores 30, so that the energy of the gas is attenuated, and the at least one silencing core 30 can ensure that the energy of the gas is attenuated more, so that the leakage sound of the turbocharger is reduced.

Note that, in the embodiment of the present application, the number of the silencing cores 30 corresponds to the number of the openings 211, that is, one silencing core 30 corresponds to one opening 211, and the position of the silencing core 30 corresponds to the position of the opening 211.

In addition, in the embodiment of the present application, when the number of the silencing cores 30 is one and the number of the openings 211 is one, at this time, the sealing cover 21 corresponds to only one opening 211, only one silencing core 30 is provided in the first cavity 111, and after the gas enters the silencing cores 30 through the opening 211, the energy of the gas is attenuated, so that the leakage sound of the turbocharger is reduced. When the number of the silencing cores 30 is plural and the number of the openings 211 is plural, at this time, the sealing cover 21 is provided with plural openings 211, and the first cavity 111 is provided with plural silencing cores 30, so that the air can be attenuated by the plural silencing cores 30 after entering the first cavity 111 through the plural openings 211, thereby further making the air leakage of the turbocharger smaller and improving the noise level of the vehicle.

In addition, in the embodiment of the present application, the number of the sound-deadening cores 30 is plural, the number of the openings 211 is plural, and one sound-deadening core 30 corresponds to one opening 211. At least one opening 211 of the plurality of openings 211 is provided with a blocking piece 212, the blocking piece 212 is movably connected with the opening 211, the blocking piece 212 is used for blocking the opening 211, and when the pressure on the blocking piece 212 is larger than the preset pressure, the blocking piece 212 unblocks the opening 211.

When the blocking member 212 is disposed in at least one opening 211 of the plurality of openings 211 and the blocking member 212 is movably connected with the opening 211, at this time, the blocking member 212 may block the opening 211, so that the gas may apply pressure to the blocking member 212 after passing through the gas leakage pipe 20, and when the pressure on the blocking member 212 is greater than the preset pressure, the blocking member 212 unblocks the opening 211, and at this time, the gas may flow into the first cavity 111 from the opening 211. In addition, gas may also flow from the opening 211 where the blocking member 212 is not provided into the first chamber 111. That is, by providing the blocking member 212 in the partial opening 211, when the pressure of the gas is small, that is, when the pressure of the exhaust gas of the turbocharger is small, the gas can directly flow from the opening 211 in which the blocking member 212 is not provided into the first chamber 111, and then the energy of the gas is attenuated by the sound deadening core 30, thereby reducing the sound of the gas. When the pressure of the gas is large, that is, when the pressure of the turbocharger is large, the gas may not only flow into the first cavity 111 from the opening 211 where the blocking member 212 is not provided, but also may cause the blocking member 212 in the opening 211 where the blocking member 212 is provided to unblock the opening 211, at which time the gas may flow into the first cavity 111 from all the openings 211 on the sealing cover 21, and then the energy of the gas is attenuated by the silencing core 30, reducing the sound of the gas. That is, by providing the blocking member 212 in at least one opening 211 among the plurality of openings 211, the relief valve seat can be made to attenuate energy against gases of different pressures, so that the functions of the relief valve seat can be diversified.

It should be noted that, in the embodiment of the present application, the material of the blocking member 212 may be a rubber material, and of course, the material of the blocking member 212 may also be other materials, such as plastic, which is not limited herein. In addition, in the embodiment of the present application, the shape of the blocking member 212 may be the same as the shape of the opening 211, for example, the shape of the opening 211 is a sector shape, and the shape of the blocking member 212 is a sector shape. In addition, in the embodiment of the present application, the edge portion of the blocking member 212 is connected to the opening 211, at this time, when the blocking member 212 receives pressure, the blocking member 212 may be pressed, so that the blocking member 212 unblocks the opening 211, so that gas may flow into the first cavity 111 through the opening 211 where the blocking member 212 is provided, and further into the sound deadening core 30.

In addition, in the embodiment of the present application, the blocking member 212 may not be disposed in one opening 211 of the plurality of openings 211, and the blocking member 212 may be disposed in the remaining openings 211 of the plurality of openings 211, at this time, when the pressure of the gas is low, for example, as the load of the engine is low, as shown in fig. 1 and 2, the pressure of the gas in the intercooler pipe body 100 is low, and when the pressure release valve is opened, the gas having the low pressure may directly flow into the first cavity 111 from the opening 211 in which the blocking member 212 is not disposed, and flow into the corresponding silencing core 30, so that the energy of the gas is attenuated, thereby achieving the effect of reducing noise. When the pressure of the gas is large, for example, in conjunction with fig. 3 and 4, the load of the engine is large, the pressure of the gas in the intercooler pipe body 100 is large, when the pressure release valve is opened, the gas with large pressure can directly flow into the first cavity 111 from the opening 211 where the blocking member 212 is not provided, and the gas with large pressure can also rush out the blocking member 212, so that the blocking member 212 is provided to unblock the opening 211, and then the gas flows into the first cavity 111 from all the openings 211 on the sealing cover 21 and flows into the silencing core 30, so that the energy of the gas is attenuated, and the effect of reducing noise is achieved.

For example, the number of the openings 211 is 8, the number of the sound deadening cores 30 is 8, and one sound deadening core 30 corresponds to one opening 211, and at this time, the blocking member 212 may be provided in each of the 7 openings 211. At this time, when the pressure release valve seat is attached to the intercooler air outlet pipe body 100 and the pressure release valve is attached to the pressure release valve seat, if the pressure of the gas in the intercooler air outlet pipe body 100 is small at the time of discharging the turbocharger, the gas having the small pressure directly flows into the first chamber 111 from the opening 211 where the blocking member 212 is not provided. If the pressure of the gas in the intercooler pipe body 100 is large, at this time, the gas having a large pressure may not only directly flow from the opening 211 where the blocking member 212 is not provided into the first cavity 111, but also the gas may flush the blocking member 212 out of the 7 openings 211 so that the 7 openings 211 are opened, and the gas may flow from the 8 openings 211 into the first cavity 111.

In the embodiment of the present application, when the relief valve seat is connected to the relief valve, the relief valve is in contact with the seal cover 21 at this time when the relief valve is not opened, and the relief valve seals the opening in the seal cover 21. When pressure relief is needed, the pressure relief valve is opened, and at this time, a gap exists between the pressure relief valve and the sealing cover 21, so that gas can flow into the first cavity 111 from the opening on the sealing cover 21 and enter the silencing core 30. If the pressure of the gas is smaller during pressure relief, after the pressure relief valve is opened, the gas may directly enter the first cavity 111 from the opening 211 where the blocking member 212 is not provided, and enter the corresponding silencing core 30. If the pressure of the gas is high during pressure relief, after the pressure relief valve is opened, the gas may rush open the blocking member 212, so that the blocking member 212 blocks the opening 211, for example, as shown in fig. 2 and 4, the blocking member 212 blocks the opening 211 in fig. 2, and the blocking member 212 unblocks the opening 211 in fig. 4.

Additionally, in some embodiments, as shown in fig. 5, an extension elbow 31 is connected to one end of at least one sound attenuating core 30, and the extension elbow 31 is located in the second cavity 112.

When the extension bend 31 is connected to one end of at least one of the sound deadening cores 30, at this time, after the gas flows into the sound deadening core 30, the gas may flow into the extension bend 31 from the sound deadening core 30, and when the gas flows in the extension bend 31, the extension bend 31 may further attenuate the energy of the gas, thereby further reducing noise. In addition, since the extension elbow 31 is located in the second cavity 112, after the gas flows out of the extension elbow 31, the gas may be exhausted from the exhaust hole in the valve seat housing 10. That is, by providing the extension bend 31, the noise of the gas can be further reduced.

When the number of the silencing cores 30 is plural, the extension bend 31 may be connected to one silencing core 30, or the extension bend 31 may be connected to each silencing core 30, which is not limited herein.

In addition, in the embodiment of the present application, when the blocking member 212 is not provided in one opening 211 among the plurality of openings 211 on the sealing cover 21, at this time, the silencing core 30 corresponding to the opening 211 may be connected to the extension elbow 31, and the other silencing cores 30 are not connected to the extension elbow 31, so that the occupied space in the second cavity 112 is small, and the extension elbow 31 is conveniently provided in the second cavity 112.

In addition, in the present embodiment, after the gas flows out of the extension bend 31, the gas may enter the second cavity 112 such that the energy of the gas is further attenuated in the second cavity 112, after which the gas is exhausted from the exhaust hole.

In addition, in some embodiments, as shown in fig. 5, a connection pipe 32 is connected to one end of at least one sound deadening core 30, and the connection pipe 32 is connected to the extension elbow 31.

When the connection pipe 32 is connected to one end of at least one of the sound deadening cores 30, at this time, the extension elbow 31 may be connected to the connection pipe 32 such that the extension elbow 31 is connected to the sound deadening core 30. That is, by providing the connection pipe 32 at one end of the sound deadening core 30, the sound deadening core 30 can be connected to the extension bend pipe 31.

In this embodiment, one end of the connecting pipe 32 may be a closed end, the other end of the connecting pipe 32 is connected to the silencing core 30, a through hole is formed in a pipe wall of the connecting pipe 32, and the extension elbow 31 is connected to the through hole. Of course, both ends of the connection pipe 32 may be non-closed ends, and in this case, one end of the connection pipe 32 may be connected to the sound deadening core 30, and the other end of the connection pipe 32 may be connected to the extension elbow 31, so that the extension elbow 31 is connected to the sound deadening core 30. The embodiments of the present application are not limited in this regard.

Additionally, in some embodiments, as shown in FIG. 1, the relief valve seat further includes a connecting end cap 40. The connecting end cover 40 is arranged in the accommodating cavity 11, the silencing core 30 is arranged on the connecting end cover 40, a first through hole is formed in the connecting end cover 40, and the silencing core 30 is opposite to the first through hole.

When the pressure release valve includes the connection end cap 40, the connection end cap 40 is disposed in the accommodating chamber 11, at this time, the sound deadening core 30 may be disposed on the connection end cap 40, thereby facilitating the disposition of the sound deadening core 30 in the first chamber 111. In addition, since the connecting end cover 40 is provided with the first through hole, the silencing core 30 is opposite to the first through hole, so that after the gas flows into the silencing core 30, the gas can flow into the first through hole on the connecting end cover 40 through the silencing core 30, flow into the second cavity 112 through the first through hole, and finally be discharged from the exhaust hole on the valve seat housing 10.
