The utility model is a kind of flushing valve piston, be to constitute by piston body, top cover, spring, piston rod, piston connection sleeve, the piston body overall structure is formed in one, the piston body external surface is provided with anti-clogging intake chamber and water inlet aperture of some inclinations, the intracavity inter-connection of water inlet aperture and piston body, piston connection sleeve is connected with the piston body bottom thread, and the adapter sleeve bottom edge is extended with the upright sheet of plurality of vertical.The utility model top cover and piston bush adopt the mode that is threaded to be installed on the piston body, easy for installation, inner spring and the piston rod construction that is provided with is simple, the plates of piston bush are the plane, and big at the clearance space between difference interval, independent extended upright sheet and the upright sheet on this plane, water outlet is unobstructed, simultaneously, piston can be fast in the flushing valve valve body on prisoner and break away from the close mouth of valve seat, reach water outlet purpose efficiently, the unlatching and the closure of flushing valve are more flexible.

Description

The flushing valve piston connection sleeve

Technical field

The utility model is a kind of flushing valve piston connection sleeve that is used for toilet facility.

Background technology

At present, toilet facility such as washbasin; the flushing valve on urinal and the water-closet generally includes two types of piston type flushing valve and diaphragm type flushing valves; wherein the piston type flushing valve has a piston usually; be used to control unlatching and the current size of water inlet to delivery port; existing multiple disclosed prior art is relevant with piston; as No. 98119583.0 " flushing valves of U.S. Si Luowen company " patent is all relevant with piston with No. 01124373.2 " piston flushing valve that has triple filter bypass pipe " patent application, this kind piston by the operating grip on the flushing valve can control valve water outlet, the piston bottom is provided with an adapter sleeve, the adapter sleeve bottom is extended with a cylindrical shape cylinder, cause the flushing valve water outlet not smooth, and the time that reaches max water yield after flushing valve is opened is longer, use sense inconvenience slightly, the installation of adapter sleeve neither be very convenient simultaneously.

The utility model content

The purpose of this utility model is to solving the problem that prior art exists, and a kind of simple in structure, easy for installation, flushing valve piston connection sleeve that water outlet is unobstructed is provided.

The utility model is achieved in that a kind of flushing valve piston connection sleeve is an overall structure, comprise connector, plates and upright sheet, connector and plates are connected as a single entity, these plates are disc, disk upper surface and bottom surface are the planes of an annular, the annular bottom surface edge of plates is extended with the upright sheet of plurality of vertical, and the outer rim development length of this upright sheet is identical with the inner edge development length, and plates and described upright sheet are connected as a single entity.

Described connector can be provided with connecting thread.

The perpendicular vertical piece of described piston connection sleeve can be provided with ribs.

Described ribs can be triangular shape, is positioned at the inner edge of upright sheet.

Described upright sheet can shrink from top to down and be down trapezoidal shape.

Upright sheet outer fringe surface can be periphery, and this periphery and plates outer fringe surface are positioned on the same periphery.

Upright sheet inner peripheral surface can be periphery, and the center of circle of inner peripheral surface is concentric with the center of circle of outer fringe surface.

Piston connection sleeve of the present utility model is an overall structure, the plates of piston connection sleeve are the plane, big at the clearance space between difference interval, independent extended upright sheet and the upright sheet on this plane, water outlet is unobstructed, simultaneously, this of adapter sleeve kind of project organization also make piston can be fast in the flushing valve valve body on prisoner and break away from the close mouth of valve seat, reach water outlet purpose efficiently, make that the unlatching of flushing valve and closure are more flexible.

Description of drawings

Fig. 1 is the elevation of the utility model piston connection sleeve;

Fig. 2 is the upward view of piston connection sleeve;

Fig. 3 is the vertical view of piston connection sleeve;

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is described in detail:

For clarity sake, the impacts flush valve piston is done one and is simply introduced, the flushing valve piston is by piston body, top cover, spring, piston rod, piston connection sleeve constitutes, during use, piston is arranged in the flushing valve valve body, make a sealing load cavity is arranged between top land and the flushing valve top, water inlet aperture by the piston middle part makes the water inlet of flushing valve water inlet be communicated with the pressure cavity simultaneously, the operating grip of flushing valve outside promotes piston rod, piston rod is opened, water in the pressure cavity is discharged from the piston delivery port, and piston integral body floats and breaks away from the flushing valve valve seat simultaneously, and the current of water inlet flow out through the delivery port of flushing valve valve seat.

With reference to figure 1-Fig. 3, piston connection sleeve 1 overall structure is formed in one, the center of piston connection sleeve 1 has limbers 6, top is the threaded connector 2 of hollow, to be connected with the bottom of piston, the connector 2 of piston connection sleeve 1 is to be connected as a single entity with plates 3, these plates 3 are disc, the disk upper surface, the bottom surface is the plane of an annular, upper surface can be placed sealing ring so that adapter sleeve 1 is connected with piston seal, the annular bottom surface edge of plates 3 is extended with the upright sheet 4 of plurality of vertical, plates 3 are connected as a single entity with upright sheet 4, the outer rim development length that should found sheet 4 is identical with the inner edge development length, makes that the clearance space between the upright sheet 4 increases, and water outlet is unobstructed.

In order to improve the intensity of piston connection sleeve 1, the perpendicular vertical piece 4 of piston connection sleeve 1 is provided with ribs 5.This ribs 5 is triangular shape, is positioned at the inner edge of upright sheet 4.

Upright sheet 4 shrinks from top to down and is down trapezoidal shape, can accelerate water yield, and upright sheet 4 outer fringe surfaces are periphery, and this periphery and plates 3 outer fringe surfaces are positioned on the same periphery.

Upright sheet 4 inner peripheral surface are periphery, and the center of circle of inner peripheral surface is concentric with the center of circle of outer fringe surface.

The global design structure of piston connection sleeve makes piston integral body float easily in the flushing valve valve body simultaneously, and water outlet is quick, and the opening and closing of flushing valve are more flexible, and are easy to use.
