Abstract

The utility model relates to a flushing tank of the toilet, in particular to a flushing tank valve. The utility model comprises a valve seat. Wherein, a water outlet is opened on the valve seat; a piston is positioned over the water outlet; the piston inserts the water outlet and an open top key; the open top key is connected with a motion bar to limit the shift position of the piston; even if the spring on the piston is broken or fails, the piston can return to the position automatically and inserts the water outlet; when adopting the open top key to push the piston upward to drain, the displacement can be controlled automatically based on the situation. The utility model utilizes the water resource reasonably and avoids the waste.

Description

A kind of flushing tank valve body

Technical field

The utility model relates to the flushing tank of washroom, specifically is a kind of flushing tank valve body.

Background technology

Tradition use in toilet flushing tank, its structure is simpler, water tank is provided with water inlet pipe and outlet pipe in the bottom, piston is stamped on the outlet pipe top, one end activity of piston is connected in water tank cavity, and the other end is connected with slide fastener, forms the current of certain impulse force when piston is opened, flow into outlet pipe, need a large amount of drainings when but piston is will be again closed at every turn, cause waste water resource, another kind of traditional use in toilet flushing tank, its structure is a water tank, the water tank side is provided with key switch, and switch connects the water valve piston in the water tank, and the water valve piston is positioned at outlet pipe and controls opening and sealing of its outlet pipe, weak point is when using a period of time, the plastic tube that connects piston is aging, dislocation and getting loose, piston will occur can not reset issues, continuous draining phenomenon occurs, can not follow border situation control displacement factually on the other hand, cause water resource waste.

The utility model content

The purpose of this utility model is to solve above-mentioned weak point, and the flushing tank valve body that a kind of random control draining water yield is provided and conserves water.

The following mode of the utility model realizes: comprise valve block, valve block has delivery port, and the delivery port top is placed with piston, and its described piston inserts in delivery port, is provided with under the piston and backs down key, backs down key and is connected with motion bar.

Be stamped piston seat on the described piston, piston seat is by keeper, and keeper top finite place piece, being connected with supporting member between keeper and the locating part forms, piston extends into keeper and locating part and constitutes spacing slip inner chamber, the locating part bottom connects an end of spring, and the spring other end peaks on the piston-top surface.

There is piston boit described piston bottom surface, and its piston boit inserts in delivery port and extends to and backs down on the key.

Described valve block upper water-out mouth is fixed with base on the delivery port, motion bar one end passes the base outer wall and is positioned at tube chamber and backs down key, and its end activity is connected on the lumen wall, is with the anti-skidding plastic handle on the motion bar other end.

Described valve block is equipped with aeration valve, and aeration valve is communicated with base and the set water-logged base of valve block.

The valve block upper surface of described piston seat side is fixed with sealing ring.

Be with suitable decorative shell on the described valve block.

The beneficial effects of the utility model are: 1, be stamped piston seat on the piston, the limited piston shift position even if the spring on the piston breaks or lost efficacy, automatically replies the position at the water pressure lower piston and inserts in delivery port; 2, utilization is backed down key and is upwards pushed the draining of piston mode open, can according to circumstances freely control displacement, rationally uses water resource, avoids causing waste.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of Fig. 1 upward view.

Fig. 3 is the broken section structural representation of Fig. 2.

The specific embodiment mode

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, 2, 3: comprise valve block 1, valve block 1 has delivery port 2, and delivery port 2 tops are placed with piston 3, and its described piston 3 inserts in delivery port 2, is provided with under the piston 3 and backs down key 4, backs down key 4 and is connected with motion bar 5.

Be stamped piston seat 6 on the described piston 3, piston seat 6 is by keeper 601, and keeper 601 top finite place pieces 602, being connected with supporting member 603 between keeper 601 and the locating part 602 forms, piston 3 extends into keeper 601 and spacing slip inner chamber 604 that locating part 602 constitutes, prevent phenomenons such as piston 3 misplaces and gets loose, locating part 602 bottoms connect an end of spring 605, and spring 605 other ends peak on piston 3 end faces.

There is piston boit 301 described piston 3 bottom surfaces, and its piston boit 301 inserts in delivery port 2 and extends to and backs down on the key 4.

Described valve block 1 upper water-out mouth 2 is fixed with base 7 on the delivery port 2, motion bar 5 one ends pass base 7 outer walls and are positioned at tube chamber 701 and back down key 4, and its end activity is connected on tube chamber 701 inwalls, is with anti-skidding plastic handle 8 on motion bar 5 other ends.

Described valve block 1 is equipped with aeration valve 9, and aeration valve 9 is communicated with base 7 and valve block 1 set water-logged base 10.

Valve block 1 upper surface of described piston seat 6 sides is fixed with sealing ring 11, and anti-sealing leaks from the water tank connection.

Be with suitable decorative shell 12 on the described valve block 1.

Operating principle: motion bar 5 is to lower swing, key 4 is backed down in order upwards makes piston 3 leave delivery port 2, current direction delivery port 2 carries out draining, and when backing down key 4 and reset, piston 3 is not backed down key 4 to upper support, under water pressure or under the elastic pressure of spring, piston 3 is shifted downwards automatically and seals its delivery port 2, stops draining, can according to circumstances need and controls the draining water yield, reach saving, the effect of environmental protection.
