Abstract

An improved structure of floating core of time delay flushing valve of the utility model comprises a floating core and a time-delay passage arranged on the floating core. A steel wire movably extends through the time-delay passage. Two ends of the steel wire are greater than the diameter of the time-delay passage. The time-delay passage can be an intake delay groove or a time-delay hole where a steel wire with both ends angled movably extends through. Because that the colatorium is changed into the steel wire and the steel wire is movably arranged in the time-delay hole when the art scheme is adopted, the movement can be made in the time-delay hole by means of hydraulic pressure when water going through to achieve the effect of prompt clearing out so as to prevent blocking of the time-delay holes. The utility model has the advantages of simple structure, convenient installation and non-required replacement, which can largely increase bulk life time of the time-delay valve.

Description

A kind of improvement structure of unsteady core of the flushing valve of delaying time

Technical field:

The utility model relates to a kind of improvement structure of unsteady core of the flushing valve of delaying time, and is especially relevant with a kind of unsteady core simple in structure, the convenient time-delay flushing valve of using.

Background technology:

The structure of the time-delay flushing valve of prior art as shown in Figure 1, comprise valve body, intake tunnel in the valve body, exhalant canal, and the core that floats, the core that should float is provided with the time-delay passage, this time-delay passage may be time-delay groove or time-delay hole, during action, the core that floats upwards lifts under the effect of hydraulic pressure, by the exhalant canal water outlet, after external force disappears, the in-core chamber of going into to float that the time-delay passage advances is to reach hydraulic balance, play the effect of delay-self-closing, existing time-delay passage is the time-delay hole, because the diameter in time-delay hole is less, easily produce when current pass through and stop up, existing solution is in the time-delay hole filter screen to be set, but the shortcoming of this kind structure is: because the grid of filter screen is closeer, easily produces and stop up, change inconvenience, therefore greatly reduce the bulk life time of time-delay flushing valve.

Technical scheme:

The utility model provides a kind of improvement structure of unsteady core of the flushing valve of delaying time, and it is simple in structure, easy for installation, need not to change, and can increase the bulk life time of time-delay valve greatly.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of improvement structure of unsteady core of the flushing valve of delaying time comprises: the core and be arranged on time-delay passage on the core that floats of floating, and the activity steel wire that stretches through in the described time-delay passage, the both ends of this steel wire are greater than the diameter of time-delay passage.

Described time-delay passage is the time-delay hole, the steel wire of the movable two ends bending that stretches through in the time-delay hole.

When described time-delay passage is the time-delay groove, the steel wire of the movable two ends bending that stretches through in the time-delay groove then.

Described steel wire top is bent into ring-type, and the bottom is bent into hook-shaped.

Adopt technique scheme, owing to change filter screen into steel wire, this steel wire is movably arranged in the time-delay hole, when current pass through, can borrow hydraulic pressure movable in the time-delay hole, reach the effect of instant mediation, can prevent the hole plug of delaying time, simple in structure, easy for installation, need not to change, can increase the bulk life time of time-delay valve greatly.

Description of drawings:

Fig. 1 is the schematic diagram of the utility model prior art;

Fig. 2 is the perspective exploded view of the utility model embodiment;

Fig. 3 is the combination action schematic diagram of the utility model embodiment.

Embodiment:

As Fig. 2, shown in Figure 3, the utility model provides a kind of improvement structure of unsteady core of the flushing valve of delaying time, comprise: core 1 and be arranged on time-delay passage 2 on the core that floats floats, described time-delay passage is for can be time-delay hole or time-delay groove, the activity steel wire that stretches through in the described time-delay passage, the both ends of this steel wire are greater than the diameter of time-delay passage; Among the embodiment time-delay passage for the time-delay hole 2, the shape of described steel wire 3 can be made the top and be bent into ring-type 31, the bottom be bent into hook-shaped 32 or other can the time-delay hole in adeciduate again other shape of activity.
