DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0020] See Figure 1-2An air intake bypass system for an alloy exhaust engine includes an intercooler 1 and a supercharger 6 connected to the air inlet of the intercooler 1. One end of the intercooler 1 is provided with a bypass intake pipe 2 connected to the intercooler 1, one end of the bypass intake pipe 2 is provided with a bypass valve 3, one end of the bypass valve 3 is provided with a bypass outlet pipe 4, one end of the bypass outlet pipe 4 is provided with a supercharger intake pipe 5, the supercharger intake pipe 5 is connected to the air inlet of the supercharger 6, a first mounting bracket 7 is detachably provided on one side of the intercooler 1, the bypass intake pipe 2 is detachably connected to the first mounting bracket 7, and the first mounting bracket 7 is located on one side of the bypass valve 3. The intercooler 1 A pressure sensor 8 is provided near one end of the bypass intake pipe 2. When the pressure sensor 8 detects that the pressure exceeds a preset value, the supercharger 6 has an excessively strong boosting capacity. At this time, the opening of the bypass valve 3 is manually adjusted to allow the excess boosted air to pass through the bypass intake pipe 2 and the bypass outlet pipe 4 and return to the supercharger 6. This allows the boosted gas to be reused. The air intake bypass system has a reasonable gas pipeline layout, which ensures the intake bypass effect. Regardless of how the environment changes, the air supercharger always maintains a reasonable boosting capacity range, which can effectively prevent the air supercharger from having an excessively strong boosting capacity, causing unstable operation of the unit.
[0021] In this embodiment, the bypass air inlet pipe 2 and the bypass air outlet pipe 4 are both provided with bellows 9 to facilitate the installation of the bypass air inlet pipe 2 and the bypass air outlet pipe 4, and the bellows 9 converts the rigid connection between the bypass air inlet pipe 2, the bypass air outlet pipe 4 and the bypass valve 3 into a flexible connection, which can avoid the vibration caused by the engine from causing the bypass air inlet pipe 2, the bypass air outlet pipe 4 and the bypass valve 3 to affect each other, thereby effectively extending their service life.
[0022] In this embodiment, stainless steel gaskets are provided between the bypass valve 3 and the bypass air inlet pipe 2 and the bypass air outlet pipe 4 to improve the sealing between the bypass valve 3 and the bypass air inlet pipe 2 and the bypass air outlet pipe 4. In addition, the stainless steel gaskets are not easy to rust in a humid environment, thereby reducing the number of maintenance times.
[0023] In this embodiment, the bypass valve 3 is a manual mechanical valve, which is easy to install and adjust, and can be used for a long time in a high temperature environment, reducing the failure rate.
[0024] In this embodiment, a second bracket 10 is further provided on one side of the intercooler 1. The second bracket 10 is detachably connected to the bypass outlet pipe 4. The second bracket 10 is detachably connected to the intercooler 1 through the base 101, which facilitates the installation of the second bracket 10 and the bypass outlet pipe 4, and also facilitates the repair and maintenance of the bypass outlet pipe 4.
[0025] In this embodiment, the second bracket 10 includes a base 101, a support rod 102, a lower fixing ring 103, and an upper fixing ring 104. The lower fixing ring 102 and the upper fixing ring 103 are both semicircular structures with the same structure, and the lower fixing ring 103 and the upper fixing ring 104 constitute a circular ring for fixing the bypass air outlet pipe 4. One end of the support rod 102 is connected to the base 101, and the other end of the support rod 102 is connected to the lower fixing ring 103. The lower fixing ring 103 and the upper fixing ring 104 are connected by bolts, which is convenient for disassembly and assembly of the bypass air outlet pipe 4 and maintenance and repair thereof. The circular ring formed by the upper fixing ring 104 and the lower fixing ring 103 can improve the stability of the bypass air outlet pipe 4.
[0026] In this embodiment, a buffer pad 11 is provided on the inner side of the lower fixing ring 103 and the upper fixing ring 104, so that the second bracket 2 and the bypass outlet pipe 4 are flexibly connected to prevent the long-term vibration of the engine from causing the connection of the bypass outlet pipe 4 to loosen, resulting in leakage.
[0027] In this embodiment, a third bracket 12 is provided on the top of the intercooler 1, and rubber pads are provided between the first bracket 7, the third bracket 12 and the intercooler 1; this prevents long-term vibration of the engine from being transmitted to the bypass intake pipe 2 and the bypass outlet pipe 4 through the rigid connection through the first bracket 7 and the third bracket 12, causing their connections to become loose and leak.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
