Abstract
The invention discloses a pedal type depth measuring self-closing valve. An auxiliary valve rod is arranged as a cross-shaped valve rod, and the lower end of the cross-shaped valve rod extends into a water inlet cavity. A pushing rod is arranged in a pedal portion. Opening and closing of the self-closing valve can be controlled through water pressure, and the self-closing valve is made to be stable in performance and good in seal property. A main valve clack is arranged as a curved main valve clack which can be tightly connected with a main valve rod. An overpressure fixed-value diaphragm is fixed to each of the upper side and the lower side of a magnet so that attraction between an upper lock plate and the magnet as well as between a lower lock plate and the magnet can be achieved in the abnormal condition, and therefore the self-closing condition of the self-closing valve is guaranteed; a seal pad is arranged between the main valve rod and the upper lock plate as well as between the auxiliary valve rod and the lower lock plate, and accordingly the seal property of the self-closing valve can be enhanced. The pedal type depth measuring self-closing valve has the advantages of being stable in performance and good in seal property and having broad market prospects.
