Zusammenfassung:	The utility model discloses a single flashboard valve which comprises a lead screw and a flashboard; wherein a fillister is arranged on the upper part of the flashboard, the head of the lead screw is in suspension connection with the fillister, a through hole which is vertical with the axis of the lead screw is provided at the head of the lead screw, a hole which is communicated with the through hole at the head of the lead screw is provided at the relevant position on the fillister, and a rope of abrasion-resistant corrosion resistant material which contains the chrome-nickel alloy passes the through to rivet the lead screw and the flashboard together. The utility model has the advantages that the riveting of the lead screw and the flashboard reduced the wallop of the liquid on the lead screw, reduces the friction between the lead screw and the flashboard, can prolong the service life of the flashboard valve to 30 times of the original, and has the advantages of simple structure, friction-resistance and corrosion-resistance in comparison with the prior art.
