Embodiment 1

[0028] Depend on Figure 1 to Figure 4 As shown, a regulating valve of the present invention includes a valve core 1, a valve seat 2, a valve cover 3 and a knob 4, the valve core 1 is arranged in the valve seat 2, the valve core 1 can rotate relative to the valve seat 2, and the valve seat 2 is provided with an inlet 21 and an outlet 22, and a passage connecting the inlet 21 and the outlet 22 of the valve seat 2 is provided between the valve seat 2 and the valve core 1. The passage includes at least one regulating section 11, and the cross-sectional area of ​​the regulating section 11 is determined by One end gradually increases or decreases gradually to the other end, the inlet 21 of the valve seat 2 is indirectly or directly communicated with one end of the regulating section 11 of the channel, and the connecting position of the valve seat outlet 22 and the regulating section 11 can be adjusted by turning the valve core 1 so that The flow adjustment between the valve seat in...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that: the inlet 21 and the outlet 22 are located at different locations, and the adjusting section 11 is installed at different locations.

[0036] Depend on Figure 5 to Figure 6 As shown, the regulating section 11 of this embodiment is arranged on the circumferential side of the flow regulating end 12 of the valve core 1 , and the inlet 21 and the outlet 22 are both located on the side wall of the valve seat part 23 of the valve seat 2 .

[0037] Wherein, the flow regulating end 12 of the valve core 1 is provided with an annular groove 19 for matching the sealing ring, and the cooperation between the annular groove 19 and the sealing ring separates the inner chamber of the valve seat 2 into two independent chambers, one chamber and the sealing ring. The inlet 21 communicates and one chamber communicates with the outlet 22 . When the inlet 21 is arranged on the valve seat part 23 of the valve seat, the end of ...

Embodiment 3

[0040] Depend on Figure 5 to Figure 8 As shown, a hydraulic damper with a damper regulating valve, the hydraulic damper includes a cylinder 9, a stator block 91 is arranged on the inner wall of the cylinder 9, a rotating shaft 90 is rotatable in the cylinder 9, and a moving shaft 90 is fixed on the rotating shaft 90. The sub-block 92, the stator block 91 and the mover block 92 divide the inner chamber of the cylinder body into two independent chambers, the cylinder body is provided with a first opening and a second opening, and one chamber of the cylinder body is connected to the first chamber. The other chamber of the cylinder communicates with the second opening, the first pipeline 93 and the second pipeline 9 are connected between the first opening and the second opening, and the first pipeline 93 and the second pipeline 9 communicate with the inlet 21 and the outlet 22 of the damper regulating valve respectively. Wherein, the rotating end 13 of the valve core 1 extends o...

Abstract

The invention aims to provide a damper regulating valve and a damper. The damper regulating valve can realize large-range and multi-gear damping regulation. The damper regulating valve comprises a valve core and a valve seat, wherein the valve core is arranged in the valve seat and can rotate relative to the valve seat; an inlet and an outlet are formed in the valve seat; a channel for communicating the inlet and the outlet of the valve seat is arranged between the valve seat and the valve core; the channel at least comprises a regulating section; the cross sectional area of the regulating section is gradually increased or gradually decreased from one end to the other end; the inlet of the valve seat is indirectly or directly communicated with one end of the regulating section of the channel; and the communicating position of the outlet of the valve seat and the regulating section can be regulated by rotating the valve core, so that the flow regulation between the inlet of the valve seat and the outlet of the valve seat is realized.

Description

technical field [0001] The invention relates to a regulating valve and a hydraulic damper used in sports training equipment. Background technique [0002] Existing exercise training equipment usually provides users with different damping during training by adjusting the weight of the counterweight. However, any kind of resistance adjustment cannot be realized, and the weight adjustment of the counterweight is very troublesome, especially for users of rehabilitation exercise equipment. [0003] In order to facilitate the adjustment of the damping size, some sports training equipment adopts hydraulic dampers, but the existing hydraulic dampers cannot realize large-scale and multi-level damping adjustments, especially it is difficult to guarantee the user experience when damping adjustments. Contents of the invention [0004] The object of the present invention is to provide a damper regulating valve capable of realizing wide range and multi-gear damping adjustment. [0005...
