[0002] Valves are control components in fluid conveying systems. They have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves are used in fluid control systems and have stability. From the simplest shut-off valve to the various valves used in extremely complex automatic control systems, there are quite a variety of varieties and specifications, and they are widely used in people's lives and production.

The valve with stability and easy maintenance, by turning the handle, the lower surface of the baffle contacts the bottom wall of the inner cavity of the valve body, driving the micro motor, so that the filter plate starts to rotate, by opening the connecting rod buckle body, the pipe cover is opened, the external water pipe is connected to the left flange, the aqueous solution is passed into the interior of the valve body, and the impurities are flushed out of the valve body through the drain pipe, so as to achieve the purpose of discharging impurities.

[0004] However, this patent still has some shortcomings. The valve stem wheel in this type of valve does not have a locking and fixing mechanism, so the stability of the valve after adjustment is poor. If it is accidentally hit or rubbed by external force, the valve stem wheel may easily rotate, thereby affecting the use of the valve to adjust the flow rate. In addition, most traditional valves cannot check the position of the valve seat in the valve body, making it difficult to judge the adjustment of the flow rate.

[0005] To this end, we proposed a valve that is stable and easy to maintain. Utility Model Content

[0023] The mounting ring 13 is fixedly mounted on the outer side of the valve body 1, and the supporting ring 15 and the sliding ring 14 are slidably connected to the outer side of the valve body 1. This design is conducive to the use of the present device. There are multiple locking grooves 17, and the multiple locking grooves 17 are circumferentially arranged on the wheel ring 12. This design is conducive to the use of the present device. The top end of the threaded rod 10 is threadedly connected to the limit bolt 20, and the bottom end of the valve body 1 is threadedly sleeved with a cover 19. By disassembling the limit bolt 20 and the cover 19, it is convenient to remove the valve seat 11 and the threaded rod 10. The depth of the first groove 5 is greater than that of the second groove 7. This design is conducive to the use of the present device.

[0024] Working principle: when in use, pull the support ring 15 downward, the support ring 15 drives the slide ring 14 downward to squeeze the spring 18, so that the slide 21 falls into the slide groove 6, at this time, the two locking rods 16 extend out of the locking groove 17, and then rotate the support ring 15 ninety degrees, so that the two slides 21 slide to the front and rear parts of the slide groove 6, release the support ring 15, the spring 18 drives the slide ring 14 back, so that the slide 21 is clamped into the second clamping groove 7, and the support ring 15 can be limited and fixed. At this time, the wheel ring 12 loses its limit, and the wheel ring 12 can be rotated, and the wheel ring 12 drives the rotating wheel 8 to rotate. Since the rotating wheel 8 is provided with a thread corresponding to the threaded rod 10, the threaded rod 10 can drive the valve seat 11 to slide downward, adjust the flow rate inside the valve body 1 or close the valve, and the above principle can also be used to lock and fix the wheel ring 12 after adjustment. , improve the stability of this valve after adjustment, according to the length of the threaded rod 10 extended, the height of the valve seat 11 in the valve body 1 can also be judged, so as to determine the adjustment size, when the valve seat 11 needs to be replaced, the rotation limit bolt 20 and the sleeve cover 19 are removed, and then the wheel ring 12 is continuously rotated to make the threaded rod 10 completely extend out of the runner 8, and the valve seat 11 and the threaded rod 10 can fall out from the bottom of the valve body 1, which is convenient for replacement. This kind of valve with stability and easy maintenance is easy to use. Through the above-mentioned components, the wheel ring 12 can be locked and fixed after the valve is adjusted, thereby further improving the stability of the valve after adjustment. At the same time, the valve seat 11 and the threaded rod 10 can be quickly disassembled and replaced, which is convenient for subsequent maintenance, and the position of the valve seat 11 in the valve body 1 can be judged according to the length of the threaded rod 10 extended, so as to facilitate the adjustment of the flow rate.
