The middle hole 4 is a fluid channel, and its size and shape can be changed according to actual needs to meet the needs of different fluid systems. The sleeve 1 and the fixed disk 2 are separately processed and then fixedly connected. Compared with the one-piece valve sleeve, the split type can be externally ground, and the accuracy can be achieved at the micron level, which is higher than the accuracy of lathe processing. The turning and milling allowance of the bar material is reduced by 60%, which can reduce costs.

[0035] Example 2:

[0036] This embodiment provides a split valve sleeve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0037] The sleeve 1 and the fixing plate 2 are welded by laser.

[0040] This embodiment provides a split valve sleeve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] The outer side of the sleeve body 1 is provided with a plurality of through holes 5 which are equidistantly distributed around the circumference.

[0042] As can be seen from this embodiment, a plurality of through holes 5 are provided on the outer side of the sleeve body 1 and are distributed equidistantly around the circumference, so as to facilitate the passage of the fluid in the valve body.

[0048] Example 5:

[0049] This embodiment provides a split valve sleeve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Noise reduction components include:

[0051] A noise reduction block 6 is fixedly provided on the inner wall of the middle hole 4, and a through groove 7 is opened inside the noise reduction block 6;

[0052] A buffer noise reduction pad 8 is fixedly installed on the inner wall surface of the through groove 7;

[0053] Sound insulation cotton 9, the inner wall surface of the through groove 7 is fixedly installed with sound insulation cotton 9 that cooperates with the buffer noise reduction pad 8 to perform secondary sound absorption, and the sound insulation cotton 9 itself has adsorption properties.

[0054] It can be seen from this embodiment that a noise reduction block 6 is fixedly provided on the inner wall of the middle hole 4. The noise reduction block 6 is a circular structure. A through groove 7 is opened inside the noise reduction block 6. The through groove 7 is a circular groove.

[0055] When the fluid flows into the sleeve 1 from the bottom of the middle hole 4, the fluid enters the through groove 7 again. At this time, when the fluid passes through the arc-shaped wall of multiple groups of buffering noise reduction pads 8, the buffering noise reduction pads 8 are made of sound insulation material. At this time, the water sound generated by the fluid's own flow and the wall of the middle hole 4 can first be buffered and blocked by multiple groups of buffering noise reduction pads 8. When the fluid passes through the sound insulation cotton 9, the sound insulation cotton 9 will first absorb the fluid. When the sound insulation cotton 9 itself is full of adsorption, when the fluid contacts and flows with the sound insulation cotton 9, the sound insulation cotton 9 itself will block the sound of the fluid flow. At this time, when the sound is discharged through the sleeve 1, the sound of the water itself when flushing out will be reduced, thereby reducing noise.
