Further improve, outer valve body and interior valve body are made by the PPR material.

By adopting the technical scheme, the beneficial effects of the utility model are that:

1. the utility model has the function of time-delay automatic reset, when in use, the valve core is pushed to overcome the return spring and move downwards by treading the pedal plate, thereby relieving the sealing state of the valve core and the inner valve body, leading the water flow to flow through the outer water inlet, the inner water outlet and the outer water outlet in sequence, when the foot of a user moves away from the pedal plate, the valve core gradually moves upwards under the action of the return spring until the valve core props against the inner water inlet, and the sealing state of the valve core and the inner valve body is opened, the device has simple structure and certain buffering function, thereby realizing the effect of water saving; meanwhile, when the utility model has a fault, the cover plate can be cleaned or the parts can be maintained and replaced only by opening the cover plate, the whole valve body is not required to be detached from the pipeline, and the maintenance cost is low;

2. the valve rod sealing ring is of a U-shaped structure with an opening, so that the valve rod sealing ring is effectively prevented from being displaced due to friction generated in the up-and-down moving process of the valve rod, and the sealing stability is improved;

3. outer valve body and interior valve body are made by the PPR material, and its intensity is high, has better shock resistance and long-term creep property, and is with low costs, long service life.
