Abstract

The utility model discloses a water discharge valve for a closet, comprising a valve body base, a floating ball of a valve body upper cover, and a sealing member. A water discharge opening and a water overflow opening are arranged on the valve body base. The floating ball is fixed below the valve body upper cover, and is buckled on the water discharge opening of the valve body base. The valve body upper cover is pivoted on the valve body base. A water leakage box is arranged on the valve body upper cover. One end of the water leakage box is provided with an opening, and the other end of the water leakage box is provided with a water discharge hole. When the water discharge valve for a closet discharges water, a water tank of a closet uses the existence of the weight of the residual water in the water leakage box to give the floating ball a torque for blocking the drop of the floating ball, the drop time of the floating ball can be effectively extended, and the water in the water tank is discharged to a water stop surface.

Description

The draining valve of toilet

The utility model relates to a kind of draining valve, refers to a kind of draining valve of toilet especially.

The toilet that we are common, be divided into monolithic toilet and split type toilet more, the height of the water tank of monolithic toilet can be slightly less than the water tank height of split type toilet, the draining valve that generally adopts of toilet all is difficult for the water in its water tank is drained on the market, surplus water can be higher than sealing face 20-40MM in the water tank, so just can influence the displacement and the developing result of monolithic toilet.

The draining valve of common toilet, mainly comprise valve base, valve upper cover, ball float and seal, why can occur having a surplus in the water tank of toilet the phenomenon of water, be because draining valve when draining, when water level is lower than ball float, the ball float fall time is very fast, and when not treating that water drains, ball float is just sealed delivery port owing to deadweight falls.

The purpose of this utility model provides a kind of draining valve of toilet, and it can prolong the fall time of ball float, effectively the water in the water tank is drained, and improves the developing result of toilet.

For achieving the above object, solution of the present utility model is: the draining valve of toilet, comprise valve base, valve upper cover, ball float and seal, and valve base is provided with a delivery port and an overfall gap; Ball float is fixed on valve upper cover below and is fastened on the delivery port of valve base, and valve upper cover is articulated on the valve base, wherein is provided with the box that leaks on valve upper cover, and box one end that leaks is made as opening, and the other end is provided with weep hole.

The draining valve of above-mentioned toilet, the weep hole outside of the box that leaks also are provided with a sheet that pulls out that adjusts the water hole size.

After adopting such scheme, because the setting of the box that leaks, the water tank that makes toilet is when the draining valve draining, existence by means of surplus water weight in the box that leaks, hinder the moment of its whereabouts for ball float one, can effectively prolong the time that ball float falls, make the water in the water tank drain into the sealing face.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is a constitutional diagram of the present utility model;

Fig. 3 is the sectional view of Fig. 2;

Fig. 4 is the rear elevation of Fig. 2;

Fig. 5 is a draining action diagram of the present utility model;

Fig. 6 is draining action sectional view.

Shown in Fig. 1,2,3,4, the utility model is made up of valve base 1, valve upper cover 2, ball float 3 and seal 5.Valve base 1 is provided with a delivery port 11 and an overfall gap 12; Valve upper cover 2 tops are provided with the box 21 that leaks, box 21 1 ends that leak are opening 211, the other end is provided with weep hole 212, leak and form one on the box and collude the aperture 213 of worrying messenger, ball float 3 is fixed on the below of valve upper cover 2, and be fastened on the delivery port 11 of valve base 1 and seal delivery port 11, valve upper cover 2 is articulated on the valve base 1.

Shown in Fig. 5,6, when the water tank of toilet begins draining, moment pull-up valve upper cover 2 and open outfall 11, when water level is lower than valve upper cover 2 and ball float 3, the moment that the existence of surplus water falls and hinder with one for ball float 3 in the box 21 of leaking, the water in the box 21 of waiting to leak when weep hole 212 has leaked fully, this time difference, to allow the water in the water tank drain fully, ball float 3 is just fallen by deadweight delivery port 11 is sealed.

Cooperate shown in Fig. 1 to 6 again, can be provided with one in weep hole 212 outsides of the box 21 that leaks and pull out sheet 4, people can regulate according to the size of water-closet tank and pull out sheet 4 with the leak size of box 21 weep holes 212 of control, thereby the time difference of the whereabouts of control ball float 3, make the water in the water-closet tank arrange light as much as possible, improve developing result.
