Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a throttle piece for a compressor. Background Technique

[0002] The throttle piece is a component applied in the refrigeration system of a compressor, and the throttle effect can be achieved through the holes on the throttle piece. According to "a throttle piece for a compressor" provided by Chinese Patent Grant Publication No. CN221443358U, the above-mentioned literature can mainly control the relative position of the semi-circular shielding disc and the disc throttle piece through locking bolts, so as to change the number of throttle holes leaking outside the disc throttle piece, realizing throttle adjustment. However, since the semi-circular shielding disc is set to two pieces, it is necessary to adjust the semi-circular shielding discs on both sides simultaneously during adjustment. This design method is relatively cumbersome and cannot expose all the throttle holes, resulting in an unsatisfactory throttle effect. Therefore, we provide a throttle piece for a compressor to solve the above problems. Content of the Utility Model

[0003] To solve the above problems, that is, to solve the problems raised in the above background technique, the utility model provides a throttle piece for a compressor, which includes a housing. A throttle piece is arranged inside the housing. A plurality of throttle holes are formed inside the throttle piece, and an adjusting piece is arranged on the top of the throttle piece.

[0004] A plurality of adjusting holes are formed inside the throttle piece, and the adjusting holes are arranged corresponding to the throttle holes. A plurality of insertion holes two are formed inside the adjusting piece, and a bolt one is inserted into the insertion hole two. The bolt one is threadedly connected to the inside of the throttle piece.

[0005] Preferably, a plurality of insertion holes one are formed at the bottom of the housing, and a bolt two is inserted into the insertion hole one. The bolt two is threadedly connected to the inside of the throttle piece.

[0006] Preferably, the plurality of throttle holes are arranged in a cross shape in an array centered on the throttle piece, and the aperture of the adjusting hole is equal to the aperture of the throttle hole.

[0007] Preferably, an inner cylinder is fixedly arranged through the inside of the throttle piece, and the adjusting piece is rotatably arranged on the outer wall of the inner cylinder.

[0008] The beneficial technical effect of the utility model is that the throttle piece can make the adjusting holes of the adjusting piece correspond to the throttle holes by setting the adjusting piece, and change the size of the throttle channel when rotating the adjusting piece. This adjustment method has the characteristics of more convenient adjustment and wider application range. Description of the Drawings

[0013] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0014] The present utility model provides a throttle piece for a compressor, including an outer shell 1. The top of the outer shell 1 is designed to be fully open, and the bottom is designed to be partially open for the flow of fluid. Inside the outer shell 1, a throttle piece 2 is provided. A plurality of throttle holes 21 are formed inside the throttle piece 2, and an adjusting piece 4 is provided on the top of the throttle piece 2. The outer diameter of the adjusting piece 4 is the same as that of the throttle piece 2.

[0015] A plurality of adjusting holes 41 are formed inside the throttle piece 2. The adjusting holes 41 are arranged corresponding to the throttle holes 21. A plurality of second jacks 42 are formed inside the adjusting piece 4. The second jacks 42 are arranged in an arc shape, and the plurality of second jacks 42 are arranged in a circular array centered on the adjusting piece 4. A first bolt 5 is inserted into the second jack 42, and the first bolt 5 is threadedly connected to the inside of the throttle piece 2. This design can change the relative position between the adjusting piece 4 and the throttle piece 2, causing the throttle holes 21 and the adjusting holes 41 to be misaligned, thereby changing the size of the throttle passage and achieving throttle adjustment.

[0016] Specifically, a plurality of first jacks 11 are formed at the bottom of the outer shell 1. A second bolt 6 is inserted into the first jack 11, and the second bolt 6 is threadedly connected to the inside of the throttle piece 2. When the throttle piece 2 needs to be repaired or replaced, the throttle piece 2 can be removed as a whole by loosening the bolt.

[0017] Specifically, the plurality of throttle holes 21 are arranged in a "rice" shape in an array centered on the throttle piece 2, and the aperture of the adjusting hole 41 is equal to the aperture of the throttle hole 21. This design can make the throttle holes 21 evenly distributed, ensuring the stability of the throttle piece 2.

[0018] Specifically, an inner cylinder 3 is fixedly arranged through the inside of the throttle piece 2, and the adjusting piece 4 is rotatably arranged on the outer wall of the inner cylinder 3. This design can ensure the stable rotation of the throttle piece 2.

[0019] Working principle: When throttling and regulating the throttle piece 2, the operator can loosen the second bolt 6, so that the regulating piece 4 can rotate on the outer wall of the inner cylinder 3. The rotating regulating piece 4 can misalign the regulating hole 41 and the throttle hole 21, thereby changing the size of the throttle passage. After the adjustment is completed, the operator can tighten the second bolt 6 to fix the regulating piece 4 on the throttle piece 2 again. When it is necessary to repair or replace the throttle piece 2, the throttle piece 2 can be removed as a whole by loosening the bolt. This installation and adjustment method replaces the original semi-circular shielding plate, making the control method and adjustment method more efficient.

[0020] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
