The invention discloses a wear-resisting valve pump which comprises a front pump cover, a rear pump cover, a bottom plate and a motor. A lining plastic pump body is connected between the front pump cover and the rear pump cover in a sleeving manner. An impeller is arranged in the lining plastic pump body. A heat insulation sheet is welded to the rear pump cover, and one end of the impeller is fixedly connected with an end assembly. A liquid injection cover is connected to the top of the lining plastic pump body in a clamped manner. One end of a liquid conveying pipe is embedded into the lining plastic pump body, and the other end of the liquid conveying pipe is connected with a coupler. A motor is connected with the coupler through a transmission shaft in a sleeving manner. A fixed pile is connected below the coupler in a clamped manner, and a connector sleeve ring is arranged above one side of the lining plastic pump body. A waterproof cover and the liquid injection pipe are arranged on a common valve pump, air corrosion caused by water soaking or long-time placing in the use process can be avoided, and a lubricating agent is added into the liquid injection pipe to relieve friction of structure operation; and all the components are made from wear-resisting manganese steel alloy materials, it can be guaranteed that the components have the same thermal expansion coefficient, and wear resistance is greatly enhanced.
