DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 12 A regulating valve with a shock-absorbing and noise-reducing mechanism comprises a valve body 1, a valve body control device 2, a stabilization auxiliary component and a shock-absorbing and noise-reducing component.

[0021] A liquid inlet 11 is provided at one end of the valve body 1, and a liquid outlet 12 is provided at the other end, a first storage cavity 13 is provided at the top of the valve body 1, and a first connecting plate 14 is provided at the top of the cavity opening of the first storage cavity 13; a valve stem 23 is provided in the valve body control device 2, the valve stem 23 is locked by a stabilizing auxiliary component, and a control handle 24 is fixedly connected to the top of the valve stem 23; a second storage cavity 21 is provided at the bottom of the valve body control device 2, and a second connecting plate 22 is provided at the bottom of the second storage cavity 21; in order to improve the stability of the valve stem 23 in use, a locking threaded column 302 is provided in the fixed ring body 301, that is, the locking threaded column 302 is rotated by the auxiliary knob 303, so that the locking threaded column 302 squeezes the side wall of the valve stem 23, thereby improving the stability of the valve stem 23.

[0022] In order to further improve the squeezing and locking effect of the locking threaded column 302 on the valve stem 23, an auxiliary pressure head 402 is arranged at the end of the locking threaded column 302, and an auxiliary bearing 404 is embedded at one end of the auxiliary pressure head 402 to cooperate with the docking plug 401 at the end of the locking threaded column 302, and conical tips 403 are evenly and equidistantly arranged at the other end of the auxiliary pressure head 402; that is, in the process of the locking threaded column 302 pushing the auxiliary pressure head 402, part of the conical tip 403 arranged at the end of the auxiliary pressure head 402 will be stuck in the thread gap on the side wall of the valve stem 23, which can further improve its locking effect; this The fixed ring body 301 in the inner stability auxiliary component is arranged on the valve body control device 2 and at the side position of the valve stem 23. A locking threaded column 302 is threadedly connected in the fixed ring body 301, and an auxiliary knob 303 is fixedly arranged at one end of the locking threaded column 302; a docking plug 401 is fixedly arranged at the other end of the locking threaded column 302, and an auxiliary slope is arranged at the side position of one end of the docking plug 401, and the docking plug 401 is inserted into the auxiliary bearing 404, and the auxiliary bearing 404 is embedded and fixedly arranged in the auxiliary pressure head 402, and a conical tip 403 is fixedly arranged at one end of the auxiliary pressure head 402 at an equal distance.

[0023] The valve stem 23 is locked by locking the threaded column 302, which can also be used in conjunction with the shock-absorbing and noise-reducing component in the sealing chamber, that is, the locking threaded column 302 improves the stability of the valve stem 23. When the liquid impacts the valve core at the bottom end of the valve stem 23, a stable valve stem 23 is obtained to reduce its vibration amplitude and reduce the noise intensity, which is more helpful to assist the noise reduction work of the cotton block 502 and the tubular sound-absorbing cotton 601, as well as the shock-absorbing work of the rubber damping column 505 and the receiving column 507.

[0024] In the process of the locking threaded column 302 driving the auxiliary pressing head 402 to move, in order to ensure the stability of the connection between the auxiliary pressing head 402 and the locking threaded column 302, the end face of the auxiliary pressing head 402 is set to be circular, and the end face diameter of the auxiliary pressing head 402 is smaller than the diameter of the locking threaded column 302; that is, in the process of the locking threaded column 302 driving the auxiliary pressing head 402 to move, the side of the auxiliary pressing head 402 will not contact the side wall of the thread groove in the fixing ring body 301, especially when the locking threaded column 302 pulls back the auxiliary pressing head 402, which can avoid the auxiliary pressing head 40 2 is loosely connected with the locking threaded column 302. The connection between the auxiliary pressure head 402 and the locking threaded column 302 is connected by the inlay connection of the docking plug 401 and the auxiliary bearing 404, which is also convenient for the disassembly and replacement of the auxiliary pressure head 402 in the later stage. Furthermore, when the locking threaded column 302 pushes the auxiliary pressure head 402 to squeeze the locking threaded column 302, due to the effect of the auxiliary bearing 404, the auxiliary pressure head 402 will not be loosened as the locking threaded column 302 rotates, which helps the conical tip 403 at the end of the auxiliary pressure head 402 to squeeze and lock the valve stem 23.

The top disc is taken out first, that is, the top blocking disk body 501 and the auxiliary cotton block 502 are extracted. In this process, the rubber damping column 505 on the bottom side of the top blocking disk body 501 is separated from the docking groove cavity 508 on the receiving column member 507, and then the receiving column member 507 is removed respectively, that is, the docking groove cavity 508 on the bottom side of the receiving column member 507 is separated from the rubber damping column 505 placed on the blocking disk body 501 at the bottom end of the sealing cavity, and finally the blocking disk body 501 at the bottom end of the sealing cavity is taken out; for its installation work, first Two of the plugging discs 501 are placed at the bottom of the sealing cavity, that is, the connecting sleeve hole groove 503 on the plugging disc 501 and the auxiliary cotton block 502 is wrapped around the side of the valve stem 23, and then placed at the bottom of the sealing cavity, and then the receiving column 507 is respectively sleeved on the rubber damping column 505 on the plugging disc 501, and then the top plugging disc 501 is installed and connected, that is, the rubber damping column 505 on the bottom side of the plugging disc 501 is inserted into the receiving column In the docking groove cavity 508 at the top of 507, the second storage cavity 21 is finally connected with the first storage cavity 13, that is, the second connecting plate 22 and the first connecting plate 14 are fixed by bolts.
