Detailed Description

The valve core for hot and cold water with large rotation angle of claim, wherein when the lever 2 moves forward to move the water hole 51 of the movable valve plate 5 to the center position of the fixed valve plate 6, the water hole 51 of the movable valve plate connects with the hot and cold water outlet 63, and the hot and cold water outlet 63 connects with the cold water inlet 61 and the hot water inlet 62, so that the hot and cold water can enter the water outlet 63 through the water hole 51 to be discharged, and the water outlet amount can be controlled by the forward movement amplitude of the lever 2.

When the shift lever 2 moves backwards to drive the water through hole 51 of the movable valve plate 5 to move outwards from the inner side of the static valve plate 6, the water through hole 51 of the movable valve plate and the cold and hot water mixing water outlet hole 63 are gradually disconnected, the communication between the cold and hot water mixing water outlet hole 63 and the cold and hot

water outlet holes

61 and 62 is also disconnected, and the valve water outlet is closed.

When the cold and hot water mixing water outlet 63 is arc-shaped and is positioned outside the arc-shaped cold water inlet 61 and the arc-shaped hot water inlet 62, the forward and backward moving deflector rods open and close water backwards, which is opposite to the embodiment.

When the valve core is in a water passing state, the deflector rod 2 is rotated clockwise to drive the movable valve plate water passing hole 51 to rotate, the movable valve plate water passing hole 51 gradually moves from a narrow position of the arc-shaped hot water inlet hole 62 to a wide position, and a wide position of the cold water inlet hole 61 gradually moves to a narrow position, and the water temperature of the mixed water outlet hole 63 gradually increases along with the increase of the hot water inlet amount and the decrease of the cold water inlet amount.

When the valve core is in a water passing state, the driving lever 2 is rotated anticlockwise to drive the movable valve plate water passing hole 51 to rotate, the movable valve plate water passing hole 51 gradually moves from a wide position of the arc-shaped hot water inlet hole 62 to a narrow position, and a narrow position of the cold water inlet hole 61 gradually moves to a wide position, and the water temperature of the mixed water outlet hole 63 gradually decreases along with the reduction of the hot water inlet amount and the increase of the cold water inlet amount.

When the shift lever 2 rotates, the limit block 31 of the rotary seat 3 is driven to rotate, and when the shift lever collides with the limit boss 11 on the inner side of the valve core shell 1, the rotation stops to limit the rotation position, and one side of the limit boss 11 on the inner side of the valve core shell 1 is the highest water temperature position, and the other side is the lowest water temperature position.

The deflector rod can also rotate to a proper position of the previous use temperature and then move forwards, the water yield is opened to a proper position, and then the temperature is finely adjusted by rotation.

Because the rotating angle of the deflector rod is close to 360 degrees, the temperature adjusting angle of the deflector rod is increased, and the water temperature is changed linearly.
