Problems solved by technology

[0002] There is no such valve in the prior art, and the relatively close technology is the traditional one-way throttle valve, which is mainly composed of a valve body and a valve core assembly, and the valve body contains a throttle The valve core assembly is plugged into the orifice, and the flow path pressure of the valve body is adjusted through the depth of the plugging, and the orifice is relatively small, so if it is used for a long time, calcium and other objects in the water will block it. The orifice, so it is often necessary to remove the valve core assembly to deal with the dirt or calcification on the orifice and the valve core assembly, but this needs to be handled with special tools, so it is very inconvenient, and the orifice is relatively deep. kind of hard

Embodiment Construction

[0014] Such as figure 1 — Figure 5 As shown, a self-cleaning manual flush valve includes a valve body 1, a valve core 2 and a handle 3, the valve body 1 is provided with a water inlet channel 11 and a water outlet channel 12, and the valve core 2 is arranged on the valve body 1, the handle 3 controls the rotation of the spool 2. In this embodiment, the middle part of the spool 2 is hollowed to form a hollow part 21, and the upper end of the spool 2 close to the handle 3 is a closed end 22. The spool 2 Boss 23 is arranged on it, and water inlet 231 is arranged on this boss 23, and when the water inlet 231 of boss 23 is aligned with the water inlet channel 11 on the valve body 1, the water inlet channel 11 only connects with the water inlet 231, so that the water Only the water inlet can enter, the valve core 2 is located between the top of the boss 23 and the inner wall of the valve body 1, and a second sealing ring 4 is arranged, and the valve core 2 is located below the sec...

Abstract

The invention relates to a valve, in particular to a self-cleaning manual flushing valve used in a reverse osmosis purification system. According to the technical scheme, the self-cleaning manual flushing valve is characterized in that a hollow part is formed in the middle of a valve element, a self-cleaning throttling mechanism is arranged in the hollow part of the valve element, the self-cleaning throttling mechanism comprises a throttling valve element, a spring and a throttling adjusting needle, a throttling hole is formed in the axial direction of the throttling valve element, and the throttling valve element can move up and down through the water pressure and the spring to achieve inserting match of the throttling adjusting needle and the throttling hole. By means of the technical scheme, the defects in the prior art are overcome, and the throttling hole can be automatically cleaned when the water pressure changes.
