Abstract
The utility model discloses a water draining valve enabling increased water draining stability. The water draining valve comprises a water draining valve main body. An inner pipe and a water draining hole are arranged inside the water draining valve main body. The bottom of an inner side of the water draining valve main body is equipped with an isolating ring that can move up and down and divides the bottom portion of the water draining valve main body into an inner chamber and an outer chamber. An inner side of the isolating ring is provided with a water output hole that is communicated with the inner chamber. The water draining valve further comprises a water supplementing channel and at least one sealing body. The water supplementing channel is used for supplementing water into the inner chamber. The at least one sealing body moves synchronously along with the inner pipe so as to fully or partially seal the water supplementing channel along with upward movement of the inner pipe and to seal the water output hole of the isolating ring along with downward movement of the inner pipe. A first water seal sheet sleeves the outside of the isolating ring. The water draining valve enables the falling speed of the isolating ring to be increased, and exhibits great water draining stability.
Description
Technical field
The utility model relates to a kind of draining valve, particularly relates to a kind of draining valve that improves draining stability.
Background technology
Traditional draining valve adopts mechanical type lever structure mostly, and this structure needs the strength that expense is larger to press the button in use, makes leverage action, mentions water sealing slice and realizes draining.For the problem of traditional this draining valve operation effort, there is a kind of novel draining valve in prior art, it is, in the inner tube lower end of draining valve, little water sealing slice is set, one floating box is set in the valve body below this inner tube, and in this floating box, water sealing slice being set, this inner tube is acted in floating box and with floating box and is realized pressure contact by little water sealing slice.When this draining valve draining, inner tube rises, and removes the effect to floating box, and floating box rises under the acting in conjunction of buoyancy and suction force upwards simultaneously, realizes large discharge capacity or small displacement draining thereby drive water sealing slice to rise.This draining valve is owing to adopting half lever construction and half floating drum boosting mechanism, thereby operation is comparatively laborsaving, convenient.But, also there is following weak point in this soft push drain valve: in its floating box dropping process simultaneously, the water that enters supply in floating box inner chamber is slowly to infiltrate into floating box inner chamber by the gap of valve body itself, thereby water inlet flow velocity is slow, cause hydraulic pressure that floating box inner side is subject to be less than by force the hydraulic pressure that floating box outside is subject to strong (when draining finishes, in water tank, still have part water, make floating box in water), thus cause floating box falling speed very slow.During due to the each draining of draining valve, the flow regime of water is different, the hydraulic pressure that floating box is subject in the time of the each draining of draining valve is also not quite identical, cause the speed of the each whereabouts of floating box not quite identical, and the falling speed of floating box is very slow, this just causes the displacement fluctuation of draining valve large (the draining undulate quantity of draining valve equals drain discharge and the poor product of floating box fall time), thereby causes the draining less stable of draining valve.
