The invention provides a valve and a turbine synchronous suction and discharge pump with the same. The valve comprises a tightening device, a driving part and an elastic hose. The driving part reciprocates, is connected with the tightening device in a driving manner, and controls the tightening device to extrude the elastic hose to be opened or closed. The valve is not made of a metal material any more, a medium flows in the elastic hose made of an non-metallic material, the valve is not prone to be corroded with the medium, particularly a corrosive medium, and scale is not likely to be formed in the valve, so that the service life of the valve is prolonged greatly.
