Abstract
The utility model relates to a closing valve of a water tank, which is provided with a valve seat 6 and a valve cover 1. The valve cover is provided with a cover body 2, a soft valve pad 4 and a pull rope 3. The soft valve pad 4 is provided with a circular barrel part 8 and a conic cylinder part 9. The closing valve has the advantages of simple structure and good sealing effect, and the utility model can achieve the effect that water leakage does not exist. After water is flushed, the valve cover can cover the valve seat in time and water loss is reduced.
Description
The utility model relates to a kind of Cistern outlet valve, specifically, relates to the draw water draught excluder of water tank of a kind of washroom.
The draught excluder of the existing case that draws water makes water only remain in the annulus of rubber valve pad because the rubber valve pad of its valve gap is split type, and therefore sealing is difficult tight, easily leaks.After having washed by water, valve gap is difficult in time covering valve seat again, also easily forms and leaks.
The purpose of this utility model provides a kind of Cistern outlet valve of good airproof performance.
The utility model Cistern outlet valve has valve seat, valve gap, and described valve gap has lid, and soft valve pad, stay cord, described soft valve pad have drum part and the awl tube part that fuses.
In described awl tube, be provided with hollow ball.
Described hollow ball is a baton round.
Described soft valve pad has the opposite projection of direction with the awl tube in the bottom of drum part, this projection is a hemispherical.
The thickness of the bottom of the drum part of described soft valve pad and awl tube part is 0.5mm-1mm.
Described thickness is 0.7mm or 0.8mm.
Has groove on the inner cylinder face of the drum part of described soft valve pad.
Because the drum of described soft valve pad part and awl tube part are whole formation, water is full of the whole space (space between lid and the soft valve pad) of valve gap, and valve gap can in time cover valve seat, and closely pastes mutually, play good sealing function, make it watertight.After the bath, valve gap can in time cover valve seat, has reduced the loss of water.Again owing in the awl tube of soft valve pad 4, be provided with hollow ball with buoyancy, so, during bath, easily mention valve gap by stay cord, the water in the water tank can in time flow out.
Fig. 1 is the front view of Cistern outlet valve described in the utility model;
Fig. 2 is the sectional view of an embodiment of soft valve pad;
Fig. 3 is the sectional view of soft another embodiment of valve pad.
Has valve seat 6 referring to Fig. 1 Cistern outlet valve described in the utility model, valve gap 1.Valve seat and valve gap all link to each other with column 7.Described valve gap 1 has lid 2, soft valve pad 4, stay cord 3.Described soft valve pad 4 has drum part 8 and the awl tube part 9 (referring to Fig. 2 and Fig. 3) that fuses.Two aperture (not shown)s are arranged on valve gap, and water can enter space between lid and the soft valve pad by this hole, makes valve gap and valve seat be able to closely paste mutually, plays good sealing function.And after the bath, valve gap can in time cover valve seat, has reduced the loss of water.In the awl tube, can also be provided with the plastic hollow ball.Owing in the awl tube, be provided with hollow ball 5, during bath, easily mention valve gap 1 by stay cord 3, the water in the water tank can in time flow out.
The material of described soft valve pad 4 can be rubber and plastic, rubber or soft pvc etc.
Referring to Fig. 3, another embodiment of soft valve pad 4 has in the bottom of drum part 8 and the opposite projection of direction of boring tube 9, and this projection is a hemispherical.
For making valve gap and valve seat fit tightlyer, the thickness of the bottom of the drum part 8 of described soft valve pad 4 and awl tube part 9 is got over Bao Yuehao, but considers durability, and its thickness is 0.5mm-1mm.Be preferably 0.7mm or 0.8mm.
Have groove on the inner cylinder face of the drum part 8 of described soft valve pad 4, so as with lid 2 on projection engages.
