A second threaded hole 205 is opened on the circumferential surface of the inner cylinder 203, so the end of the outer force-bearing shaft 204 is threadedly connected to the second threaded hole 205.

[0033] The inner rotating cylinder 101 is provided with an oblique sliding groove 105 that cooperates with the outward force-bearing shaft 204.

[0034] The outer rotating cylinder 102 is provided with a transverse sliding groove 106 that cooperates with the extended force-bearing shaft 204. The center points of the transverse sliding groove 106 and the inclined sliding groove 105 coincide.

[0035] The assembly process of this utility model is as follows:

[0036] Step 1: Place the center limiter 104 in a suitable position and fix it with temporary support;

[0037] Step 2: Connect the disc spring assembly 201 and the inner cylinder 203 of the rotary valve 202 to the center limiter 104 in sequence at both ends and temporarily fix them.

[0038] Step 3: Place the inner rotating cylinder 101 around the center limiter 104;
