[0021] Based on the foregoing prior art, the throttling cylinder 2 comprises an upper half cylinder 21, a lower half cylinder 22, a positioning ring 23 and a connecting ring 24. The upper half cylinder 21 and the lower half cylinder 22 can be mutually spliced, and a plurality of upper ridges 3 and a plurality of lower ridges 4 are integrally formed on the inner walls of the upper half cylinder 21 and the lower half cylinder 22, respectively.

The positioning ring 23 is coaxial with the upper half cylinder 21 and is integrally formed at one end of the upper half cylinder 21. A plurality of through holes located on the same circumference are formed on the positioning ring 23. The diameter of the circumference of the plurality of through holes is greater than the inner diameter of the flow channel 1. A positioning groove 11 for accommodating the positioning ring 23 is formed at one of the ports of the flow channel 1. Threaded holes corresponding to the plurality of through holes are arranged on the groove bottom of the positioning groove 11. Threaded holes are formed on the end face of the upper half cylinder 21 away from the positioning ring 23. Threaded holes are formed on the two end faces of the lower half cylinder 22. An inner through hole corresponding to the threaded hole on the end face of the lower half cylinder 22 is also formed on the positioning ring 23. The connecting ring 24 is provided with two counterbores corresponding to the threaded holes of the upper half cylinder 21 and the lower half cylinder 22, respectively;

[0022] In the assembling process, the lower half cylinder 22 is moved to be opposite to the upper half cylinder 21 so that the lower half cylinder 22 and the upper half cylinder 21 are combined together, then the lower half cylinder 22 is moved along the length direction of the upper half cylinder 21 so that one end surface of the lower half cylinder 22 is tightly attached to the end surface of the positioning ring 23, then the bolts are screwed through the inner through holes and into the lower half cylinder 22 so that the lower half cylinder 22 is fixedly connected with the positioning ring 23, then the connecting ring 24 is attached to the end surface formed by the lower half cylinder 22 and the upper half cylinder 21, the bolts are screwed through the countersunk holes and into the lower half cylinder 22 and the upper half cylinder 21 so that the lower half cylinder 22 and the upper half cylinder 21 are fixedly connected with the connecting ring 24, the both ends of the lower half cylinder 22 are fixed so as not to be separated from the upper half cylinder 21, the nut part of the bolt is accommodated in the large end of the countersunk hole, finally the throttle cylinder 2 is inserted into the flow channel 1 until the positioning ring 23 is in contact with the groove bottom of the positioning groove 11, the bolts are screwed through the through holes distributed in the circumference and into the groove bottom of the positioning groove 11 so that the throttle cylinder 2 is positioned in the flow channel 1;

[0023] After long-term use, a large amount of impurities are accumulated between the adjacent lower ridge 4, and the upper ridge 3 surface is attached with impurities, the bolts connecting the positioning ring 23 and the positioning groove 11 are removed, then the throttle cylinder 2 is removed from the flow channel 1, the parts that can be washed are preliminarily washed with water, at the same time the groove of the bolt is exposed, then the bolt is unscrewed by using a flathead screwdriver, the connecting ring 24 is removed, the bolts connecting the lower half cylinder 22 and the positioning ring 23 are unscrewed by using a wrench, then the lower half cylinder 22 and the upper half cylinder 21 are separated and washed independently until the cleaning requirement is met, finally the components are reassembled and put back into the flow channel 1 for reuse;

[0024] The design can separate the throttle cylinder 2 for fully and effectively washing each position in the throttle cylinder 2, improve the reuse rate of the throttle cylinder 2, indirectly reduce the cost of the user and reduce the waste of resources; in addition, the throttle cylinder 2 can slow down the erosion of the medium to the inner wall of the flow channel 1, effectively ensure the structural stability of the ball, and prolong the service life of the ball; compared with the design that the positioning ring 23 and the upper half cylinder 21 are integrally formed, the design that the positioning ring 23 and the upper half cylinder 21 can be separated can reduce the assembling steps of the throttle cylinder 2, and because the position between the positioning ring 23 and the upper half cylinder 21 is fixed, the accuracy of the installation position of the lower half cylinder 22 is improved, and the assembling efficiency is indirectly improved.

[0025] As an improved embodiment, refer to Figure 4 and Figure 6As shown, the lower half cylinder 22 is integrally formed with a limiting block 26 connected to the inner wall of the lower half cylinder 22 on the surface that is attached to the upper half cylinder 21, and the upper half cylinder 21 is provided with a limiting groove 25 matched with the limiting block 26. After the upper half cylinder 21 and the lower half cylinder 22 are attached to each other, the limiting block 26 is inserted into the limiting groove 25. Compared with the design that the surfaces of the upper half cylinder 21 and the lower half cylinder 22 are both flat, the design can avoid the radial movement of the lower half cylinder 22 relative to the upper half cylinder 21, effectively improve the position stability of the lower half cylinder 22 after being assembled with the upper half cylinder 21, and ensure the smooth connection of the positioning ring 23 and the connecting ring 24 with the lower half cylinder 22.

[0026] As a specific embodiment of the improvement, refer to Figures 2 to 4 As shown, the flow channel 1 is provided with a blocking ring 12 matched with the end face of the connecting ring 24 at the port away from the positioning groove 11. The inner diameter of the blocking ring 12 is less than or equal to the inner diameter of the connecting ring 24. In the case that the medium flows from the connecting ring 24 to the positioning ring 23, the blocking ring 12 effectively prevents the medium from generating a thrust on the throttle cylinder 2, thereby affecting the connection stability between the positioning ring 23 and the positioning groove 11. At the same time, the blocking ring 12 can prevent impurities in the medium from being filled into the countersunk hole and the groove of the slot head bolt, thereby ensuring the structural stability of the slot head bolt, reducing the difficulty of flushing the slot head bolt, and improving the efficiency of disassembling the slot head bolt.

[0027] As a specific embodiment of the improvement, due to processing errors, there may be a gap between the connecting ring 24 and the blocking ring 12, which causes impurities to be clamped in the slot head bolt, thereby affecting disassembly. To solve the foregoing problem, refer to Figure 2 As shown, a soft sealing ring 5 is arranged between the blocking ring 12 and the connecting ring 24. The sealing ring 5 can be made of rubber with elastic deformation. This design not only prevents impurities from entering the countersunk hole, but also prevents the medium from entering the gap between the flow channel 1 and the throttle cylinder 2, thereby effectively ensuring the smoothness of disassembling the throttle cylinder 2 from the flow channel 1.

[0028] As a specific embodiment of the improvement, refer to Figure 2 As shown, a gasket 6 is arranged between the positioning ring 23 and the positioning groove 11. This design not only improves the sealing between the positioning ring 23 and the positioning groove 11, but also compensates for the gap caused by processing errors, thereby improving the connection compactness.

[0029] As a specific embodiment of the improvement, refer to Figure 2 As shown, the end face of the connecting ring 24 facing the positioning ring 23 is provided with a soft sealing element 7 that can be attached to the upper half cylinder 21 and the lower half cylinder 22. This design can improve the sealing between the upper half cylinder 21, the lower half cylinder 22, and the connecting ring 24, prevent the medium from entering the gap between the flow channel 1 and the throttle cylinder 2, and effectively ensure the smoothness of disassembling the throttle cylinder 2 from the flow channel 1.

[0030] As a specific embodiment of the improvement, refer to Figure 2 As shown in the drawings, the upper half cylinder 21 and the lower half cylinder 22 are attached to each other on the surface of the upper half cylinder 21 and the lower half cylinder 22, and the lower half cylinder 22 is attached to the positioning ring 23. The sealing layer 8 is arranged on the surface of the upper half cylinder 21 and the lower half cylinder 22 and the surface of the lower half cylinder 22 and the positioning ring 23. The sealing layer 8 can be made of soft rubber. The design can improve the sealing performance between the upper half cylinder 21 and the lower half cylinder 22, and can fill the gap between the lower half cylinder 22 and the positioning ring 23 or the connecting ring 24 due to insufficient length, effectively improve the sealing performance between the lower half cylinder 22 and the positioning ring 23, prevent the medium from entering the gap between the flow channel 1 and the throttle cylinder 2, and effectively ensure the smoothness of the disassembly and assembly of the throttle cylinder 2 from the flow channel 1.
