Abstract
The invention discloses an automatic constant-pressure constant-flow valve for pipeline water-pressure water-flow control. The valve comprises a valve body, a water inlet and a water outlet, wherein a limit block is connected at one end of an inner cavity of the valve body; the water inlet is arranged in the middle of the limit block; a piston, a spring, a spring base and an adjusting rod are sequentially arranged in the inner cavity of the valve body; the piston is arranged between the limit block and the spring; the spring is arranged between the piston and the spring base; the adjusting rod is arranged at the other side of the spring base; the water inlet is arranged on the piston; the water outlet is arranged on the side surface of the middle part of the valve body; the exit of the water inlet corresponds to an inner cavity of the spring; the water outlet is communicated with the outer side of the spring; or the exit of the water inlet corresponds to the outer side of the spring; and the water outlet is communicated with the inner cavity of the spring.
