[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] Example 1

[0025] Reference Figure 1 , Figure 2, a dual-chamber throttle valve adjustment device, used for adjusting the opening of the dual-chamber throttle valve, includes a connecting body 1000, the connecting body 1000 is provided with an air flow channel group, the air flow channel group includes two air flow channels, the air flow channels run through the connecting body 1000; the two air flow channels are used to be connected to the cavity of the dual-chamber throttle valve in a one-to-one correspondence; the air flow channel includes a matching section 1100, and a first blocking member 2000 is provided in the matching section 1100; the air flow channel also includes a first closing section 1200 connected to one end of the matching section 1100, and one end of the first blocking member 2000 is provided with a first abutting body 2100 for abutting against the first closing section 1200; a blocking body 2300 is provided on the side wall of the first blocking member 2000, the first abutting body 2100 is sleeved on the first blocking member 2000, and one end of the first abutting body 2100 abuts against the blocking body 2300. An airflow gap is provided between the side wall of the first blocking member 2000 and the channel wall of the matching section 1100, and the airflow gap extends to the first closing section 1200. The dual-chamber throttle valve adjustment device also includes a driving device for driving the first blocking member 2000 to move in the matching section 1100, the driving device includes a driving body 3100 and a connecting rod 3200, and the driving device can be set in the form of a cylinder, a hydraulic cylinder, a linear motor, etc.; the airflow channel also includes a second closing section 1300 connected to the other end of the matching section 1100, the connecting rod 3200 passes through the second closing section 1300, and the connecting rod 3200 is connected to the other end of the first blocking member 2000; the other end of the first blocking member 2000 is provided with a second abutting body 2200 for abutting against the second closing section 1300. The arrangement of the second closing section 1300 and the second abutment body 2200 can move the first blocking member 2000 to a position where the second closing section 1300 abuts against the second abutment body 2200, thereby adding an extra layer of sealing to the interface between the connecting body and the driving device, thereby better ensuring the sealing performance of the dual-chamber throttle valve adjustment device; in addition, it also provides a buffer for the first blocking member 2000 and reduces impact loss.

[0026] Specifically, Figure 1 As described above, the mating section 1100 is configured as a hole extending in the left-right direction, the first blocking member 2000 is configured as a stepped column extending in the left-right direction, the blocking body 2300 on the first blocking member 2000 is configured as a circular step, the first abutting body 2100 and the second abutting body 2200 are both configured as annular sealing gaskets, and the outer side surfaces of the two sides of the blocking body 2300, the first abutting body 2100, and the second abutting body 2200 are coplanar, forming a uniform airflow gap with the inner wall surface of the mating section 1100, i.e., the hole wall surface, thereby reducing startup noise.

[0027] The air flow channel also includes an air inlet section 1400 connected to the matching section 1100 and an air outlet section 1500 connected to the first closing section 1200. In this embodiment, the air outlet sections 1500 of the two air flow channels are connected, that is, the two air flow channels share a common air outlet end, making the dual-chamber throttle valve adjustment device more compact.

[0028] like Figure 1 and Figure 2 As shown, the air intake section 1400 includes a connecting port 1401 arranged on the mating section 1100, and a diameter D of the connecting port 1401 along a direction from one end of the first blocking member 2000 to the other end of the first blocking member 2000 is greater than a distance L from one end of the first blocking member 2000 to the other end of the first blocking member 2000. The blocking member 2000 will not completely block the connecting port 1401 in the left and right directions, so that the airflow always has an outlet part at the connecting port 1401, thereby avoiding the impact vibration of the airflow and avoiding the impact noise of the airflow.

[0029] The axis lines of the matching sections 1100 of the two airflow channels are arranged in a colinear manner, and the distance between the axis lines of the air intake sections 1400 of the two airflow channels gradually increases in the direction close to the matching section 1100, which provides more movement strokes for the two first blocking members 2000 in the two airflow channels and reduces the relative dimensional accuracy requirements of the first blocking members 2000. The air intake section 1400 includes a first hole section 1410, a second hole section 1420, and a third hole section 1430 connected in sequence, and the third hole section 1430 is connected to the matching section 1100; the axis lines of the first hole section 1410 and the third hole section 1430 are both perpendicular to the axis line of the matching section 1100, the axis line of the second hole section 1420 is parallel to the axis line of the matching section 1100, and the extension line of the axis line of the second hole section 1420 intersects with the end face of the connector 1000. In this embodiment, the distance between the axis centers of the first hole segments 1410 of the two air flow channels is smaller than the distance between the axis centers of the two third hole segments 1430 .

[0030] The second hole section 1420 includes a blind hole section 1421 and a second blocking member 1422 for blocking the blind hole section 1421, and the second blocking member 1422 is detachably connected to the blind hole section 1421. In this embodiment, the second hole section 1420 is arranged along the left-right direction, and the second hole section 1420 is arranged in the form of the blind hole section 1421 plus the second blocking member 1422, which improves the processing convenience of the second hole section 1420.

[0031] The connector 1000 includes a first connecting section 1001 and a second connecting section 1002 abutting against each other, the first hole section 1410 and the second hole section 1420 are arranged on the first connecting section 1001, and the third hole section 1430 includes a first end hole 1431 extending inwardly along the abutting surface of the first connecting section 1001 and a second end hole 1432 extending inwardly along the abutting surface of the second connecting section 1002. The third hole section 1430 is provided with a disconnected surface in the middle, so that the structure of the first hole section 1410, the second hole section 1420 and the third hole section 1430 with a tortuous axial centerline is easy to process, that is, the first end hole 1431 and the second end hole 1432 can be processed separately first, and then the two are combined into the third hole section 1430.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
