The sliding range of the driving rod 61 is adjusted through the size of the floating range of the water pressure value of the water pressure of the water inlet pipe in the area, the adjusting range is increased through clockwise rotation, and the adjusting range is decreased through counterclockwise rotation. When the water pressure value range is small, the relative positions of the second water passing port 57 and the third water passing port 58 are correspondingly adjusted only in a small range, so that the adjusting outer sleeve 51 and the adjusting inner sleeve 52 are less in mutual blocking in the sliding range, and the flow of the water body is reduced; when the water pressure value range is large in floating, the sliding range of the driving rod 61 is correspondingly enlarged, so that the adjusting outer sleeve 51 and the adjusting inner sleeve 52 can be adjusted independently in a large sliding range, and the water flow is reduced by blocking each other in a certain range.
When the water pressure at the water inlet end is suddenly increased, the water pressure drives the water body to move downwards into the lower cavity 64 to increase the cavity pressure in the lower cavity, so that the cavity pressure is consistent with the water pressure, the balance between the adjusting inner sleeve 52 and the return spring 60 is broken, the adjusting sheet 62 is upwards supported to drive the driving rod 61 to drive the adjusting inner sleeve 52 to upwards slide, the second water passing port 57 and the third water passing port 58 are mutually sealed, the flow of the water body passing through the second water passing port 57 and the third water passing port 58 is reduced, and the return spring 60 is upwards extruded at the same time, so that the elastic potential energy of the return spring 60 and the cavity pressure of the lower cavity 64 are; when the water pressure at the water inlet end is suddenly reduced, the cavity pressure of the lower cavity 64 is greater than the water pressure, water flows back into the water inlet end from the lower cavity 64, the balance between the adjusting inner sleeve 52 and the return spring 60 is broken, the return spring 60 pushes the adjusting inner sleeve 52 downwards, the driving rod 61 is driven to slide downwards to drive the adjusting sheet 62 to retract downwards, the flow passing through the second water passing port 57 and the third water passing port 58 is increased, and meanwhile, the elastic potential energy of the return spring 60 and the cavity pressure of the lower cavity 64 are balanced again.
The use method of the invention is that the invention can be connected and arranged on the cold water inlet pipeline or the hot water inlet pipeline or simultaneously arranged on the cold water inlet pipeline and the hot water inlet pipeline. The outlet water temperature of the mixed water is set through a liquid crystal panel of the controller, and the water temperature is monitored in real time through a temperature sensor. When the water pressure of the cold water pipe is increased or the water pressure of the hot water pipe is reduced, the temperature sensor monitors that the temperature of the outlet water is lower than a set value, the controller drives the driving motor 41 of the valve arranged on the cold water inlet pipe to rotate, so that the valve rod 14 drives the arc-shaped valve plate 15 to move towards the first water passing opening 13, and the water passing area of the first water passing opening 13 is blocked to reduce the supply of the cold water; the controller drives a driving motor 41 of a valve arranged on the hot water inlet pipe to rotate, so that the valve rod 14 drives the arc-shaped valve plate 15 to move towards the direction far away from the first water passing opening 13, and the water passing area of the first water passing opening 13 is reduced to be blocked so as to increase the supply of hot water. When the outlet water temperature of the mixed water returns to the set value, the controller controls the driving motor to stop moving.
When the water pressure of the hot water pipe is increased or the water pressure of the cold water pipe is reduced, the temperature sensor monitors that the temperature of the outlet water is higher than a set value, the controller drives the driving motor 41 of the valve arranged on the cold water inlet pipe to rotate, so that the valve rod 14 drives the arc-shaped valve plate 15 to move towards the direction far away from the first water passing port 13, and the blockage to the water passing area of the first water passing port 13 is reduced to increase the supply of cold water; the controller drives the driving motor 41 of the valve arranged on the hot water inlet pipe to rotate, so that the valve rod 14 drives the arc-shaped valve plate 15 to move towards the first water passing opening 13, and the water passing area of the first water passing opening 13 is blocked to supply less hot water. When the outlet water temperature of the mixed water returns to the set value, the controller controls the driving motor to stop moving.
The second control device assists adjustment according to changes in water pressure. When the valve rod 14 and the arc valve plate 15 are not driven by electric energy to act, the second control device automatically adjusts the flow of the water body within a setting range in the process of water pressure change according to the setting of a user, and the effect of adjusting the water temperature is achieved.
