Existing automotive exhaust gas treatment valve bodies generally control the entry and isolation of exhaust gases through valves. However, in use, existing valves rely on springs to control the sealing blocks for automatic sealing. Over time, the spring elasticity decreases, leading to insufficient sealing capacity and allowing exhaust gases to enter. Therefore, the aforementioned problems need to be addressed and improved.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses an adjustable automotive exhaust gas treatment valve body with adjusting bolts, comprising an exhaust pipe 1, an intake pipe 3 horizontally fixed to the middle of one side of the exhaust pipe 1, and a sealing groove opened at the lower end of the exhaust pipe 1. The intake pipe 3 communicates with the middle of the exhaust pipe 1, and a sealing mechanism is installed inside the exhaust pipe 1. An adjusting mechanism is installed on the sealing mechanism, which facilitates the control of exhaust gas entering the engine. A fixing plate 2 is installed at the lower end of the exhaust pipe 1. The fixing plate 2 has mounting grooves at both ends, and the top surface of the fixing plate 2 is fixed to the intake pipe 3. A vacuum tube is installed at the upper end, and the lower end of the vacuum tube is fixedly connected to the upper end of the exhaust pipe 1 and the intake pipe 3. A suction pipe 4 is connected to one side of the vacuum tube. A mounting block is fixedly connected to one side of the top surface of the vacuum tube. The mounting block is cylindrical and can be fixed to the valve body through the fixing plate 2, which facilitates the normal operation of the valve body. The sealing mechanism includes a sealing block 7 installed in the sealing groove. The sealing block 7 has an isosceles trapezoidal cross section and multiple sealing rings 11 are installed on the outside of the sealing block 7. A connecting rod is fixedly connected to the upper end of the sealing block 7. The sealing block 7 and the sealing rings 11 can seal the exhaust pipe 1 to prevent the exhaust gas from entering.

[0020] In this invention, a limiting groove is provided inside the connecting rod, which communicates with the vacuum tube. A sliding groove is provided at the lower end of the connecting rod, which communicates with the limiting groove. The connecting rod passes through one end of the vacuum tube and its upper end is placed inside the vacuum tube. The connecting rod and the sliding groove facilitate the installation of the adjusting plate 8 on the sealing block 7 for sealing and opening. The adjusting mechanism includes an adjusting plate 8 slidably connected within the sliding groove. A spring 5 is sleeved on the adjusting plate 8. One end of the spring 5 is connected to the outer bottom surface of the adjusting plate 8, and the other end of the spring 5 is connected to the top surface of the sealing block 7. A bolt 6 is fixed to the inner top surface, and the sealing block 7 is automatically sealed by the spring 5 and the sealing block 7. The upper end of the bolt 6 has a threaded groove, and the lower end of the bolt 6 is fixed to a second sealing ring 10, which is in contact with the limiting groove. The upper end of the bolt 6 is threaded to the vacuum tube, and the top surface of the bolt 6 has an internal hexagonal groove. A first sealing ring 9 is installed on the outer side of the top of the bolt 6, and the outer side of the first sealing ring 9 is in contact with the inner wall of the mounting block. The elasticity of the spring 5 can be adjusted by the bolt 6 and the adjusting plate 8, thereby controlling the sealing strength.

[0021] Working principle: When using this utility model, the device is first fixed by the fixing plate 2. When the valve body needs to be opened, the intake pipe 4 draws in air, causing the connecting rod to retract and move the sealing block 7 upward. At this time, the exhaust pipe 1 opens and connects with the intake pipe 3, allowing exhaust gas and external gas to enter through the intake pipe 3 to suppress the engine's reaction. When the valve body needs to be closed, the intake pipe 4 is stopped, restoring the air pressure in the vacuum tube. This causes the spring 5 to push the sealing block 7 downward to seal the exhaust pipe 1, and the engine reaction returns to normal. When the internal sealing block 7 cannot completely seal the exhaust pipe 1 due to long-term use, the bolt 6 is rotated by a tool to drive the adjusting plate 8 downward to compress the spring 5, thereby improving the sealing strength of the sealing block 7.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
