Specifically, when the control valve 21 is opened, the water flow in the water inlet pipeline 20 is in a flowing state, when the water demand exists, the water outlet 1 is in an opening state, when the water flow flows out from the water outlet 1, the pressure in the inner cavity 11 is reduced, at this time, the pressure of the water pressure acting on the sliding adjusting assembly 13 is reduced, the sliding adjusting assembly 13 is unbalanced in stress due to the acting force of the adjustable elastic assembly 14, the sliding adjusting assembly 13 slides downwards for a certain distance to keep the stress balance, a gap exists between the sliding adjusting assembly 13 and the outlet of the middle hole 121, and the water flow flows out from the gap at a constant flow rate; when the pressure in the inner cavity 11 is further increased or decreased, the sliding adjusting component 13 automatically slides upwards or downwards along with the pressure change in order to keep the stress balance, and the gap between the sliding adjusting component 13 and the outlet of the middle hole 121 is decreased or increased, so that the water outlet flow rate is automatically adjusted under a certain water outlet pressure, the water outlet stability of the angle valve can be ensured, and the water resource waste caused by unstable water outlet is avoided. If the pressure in the inner cavity 11 is kept unchanged, the adjustment of the water outlet pressure and the water outlet flow rate can be realized by adjusting the acting force of the adjustable elastic component 14 on the sliding adjusting component 13, the used water reaches an ideal state meeting the water use requirement, the adjustable range of the water outlet pressure of the angle valve is measured to be 0-0.8MPa, and the adjustable range of the water outlet flow rate is measured to be 0-40L/min (liter/minute). When the water outlet 1 is in a closed state when the water demand does not exist, the pressure in the inner cavity 11 is restored to the pressure equal to that at the water inlet 2, the sliding adjusting component 13 slides upwards to keep the stress balance so as to close the gap between the sliding adjusting component 13 and the outlet of the middle hole 121, and the flow rate of water flow in the middle hole 121 is zero at the moment.

The sidewall channel 123 may be used to communicate the two ends of the control lever housing 12 to ensure that the pressure at the two ends of the control lever housing 12 is equal. The number of the sidewall through grooves 123 may be two or more, and specifically, the sidewall through grooves 123 may be arranged at equal intervals on a circumference around the center hole 121.
In one embodiment, the sliding adjustment assembly 13 includes a control rod 131, a diaphragm 132, a support plate 133, a control rod screw 134, and a control rod nut 135; the control rod screw 134 sequentially penetrates through the supporting plate 133, the membrane 132 and the control rod 131, and is fixedly connected with the control rod nut 135 arranged at the end 134 of the control rod screw to form a whole. Wherein, the cross section of the control rod 131 is I-shaped; a first sealing ring 1311 and a second sealing ring 1312 are arranged on the control rod 131; a diaphragm groove 1321 is formed in the diaphragm 132 at a position opposite to the sidewall through slot 123. The first sealing ring 1311 can seal the gap between the h-shaped control rod 131 and the middle hole 121 to ensure that the water flow in the middle hole does not flow upward, and can further increase the stability of the angle valve in adjusting the flow rate of the outlet water, the second sealing ring 1312 can seal the gap between the h-shaped control rod 131 and the outlet of the middle hole 121 to ensure that the water flow cannot flow out of the gap between the sliding adjustment assembly 13 and the outlet of the middle hole 121 when the gap between the sliding adjustment assembly 13 and the outlet of the middle hole 121 is sealed, and specific installation positions of the first sealing ring 1311 and the second sealing ring 1312 are shown in fig. 1 and 4.
