This water intaking valve under any circumstance can not produce the phenomenon of closestool water reflux to the water supply line in to guarantee the pureness of running water.
Description
Technical field
The utility model relates to field of sanitary ware, more particularly, relates to a kind of backflow proof closestool water inlet valve.
Background technology
People's closestool water inlet valve used in everyday will produce backflow as Rig up error, makes the water in water-closet tank be back in water supply pipe, pollutes to tap water.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of backflow proof closestool water inlet valve, and this water intaking valve can produce backflow phenomenon in no instance, thus ensures the pure of tap water.
The purpose of this utility model is reached by following measure:
A kind of backflow proof closestool water inlet valve, comprises interior pipe, outer tube and water inlet component, is characterized in: described water inlet component is installed on outer tube, described outer tube sleeve is established on inner pipe, seal between outer tube and interior pipe, outer tube can adjust up and down along interior pipe, and described interior pipe is communicated with the blow-off pipe of toilet.
Described water inlet component comprises float tank, float, lever, water inlet head, water inlet lid, sealing rubber cushion, water diversion disk, anti-siphon rubber cushion and inlet channel, be characterized in: described float is installed in float tank, the power arm of float and lever joins, lever is installed in and covers into water, water inlet mounts cover and is located at on water head, be provided with spout hole between water inlet head and outer tube, sealing rubber cushion is installed in in water lid, and water diversion disk and anti-siphon rubber cushion are installed in in water head.
The beneficial effects of the utility model are, this water intaking valve can produce backflow phenomenon in no instance.

Fig. 2 is the utility model backflow proof closestool water inlet valve course of work sectional view;
Fig. 3 is the course of work sectional view of the anti-backflow of the utility model backflow proof closestool water inlet valve;
Fig. 4 is the sectional view that the utility model backflow proof closestool water inlet valve is in overflow situation.
Detailed description of the invention
As shown in Figure 1, the utility model backflow proof closestool water inlet valve, comprise interior pipe 1, outer tube 2 and water inlet component 3, be characterized in: described water inlet component 3 is installed on outer tube 2, described outer tube 2 is set on interior pipe 1, seal between outer tube 2 and interior pipe 1, outer tube 2 can adjust along interior pipe about 1, and described interior pipe 1 is communicated with the blow-off pipe of toilet.
Described water inlet component 3 comprises float tank 31, float 32, lever 33, water inlet 34, water inlet lid 35, sealing rubber cushion 36, water diversion disk 37, anti-siphon rubber cushion 38 and inlet channel 39, be characterized in: described float 32 is installed in float tank 31, float 32 joins with the power arm of lever 33, lever 33 is installed in on water lid 35, water inlet lid 35 is installed in on water head 34, water inlet is provided with spout hole between 34 and outer tube 2, sealing rubber cushion 36 is installed in in water lid 35, and water diversion disk 37 and anti-siphon rubber cushion 38 are installed in in water head 34.
The course of work of the utility model backflow proof closestool water inlet valve is as follows:
As shown in Figure 2, the relief hole 351 on water inlet lid 35 is with water inlet lid 35 and seal the transformation chamber 352 formed between rubber cushion 36 and communicate, and transformation chamber 352 is communicated with water inlet 341 by the aperture sealing rubber cushion 36 middle.During water inlet, the resistance arm of lever 33 does not seal relief hole 351, from the water that water inlet 341 enters, a part is flowed in transformation chamber 352 by the aperture in the middle of sealing rubber cushion 36, then flows out from relief hole 351 again, therefore pressure is not had in transformation chamber 352, another part water entered from water inlet 341 as illustrated with black arrow, backs down sealing rubber cushion 36, flows out from the hole water diversion disk 37, and back down anti-siphon rubber cushion 38, flowed in water-closet tank by inlet channel 39.When float tank 31 fills water, float 32 floats, the power arm that float 32 promotes lever 33 rotates, the resistance arm of lever 33 seals into the relief hole 351 on water lid 35, and at this moment, the water entered in transformation chamber 352 from water inlet 341 is hopeless, pressure in transformation chamber 352 is increased, under pressure, sealing rubber cushion 36 seals water inlet 341, and water inlet stops.Now the water level of water-closet tank is called working water level, referred to as WL.
Refer to Fig. 3, when tap water cut-off, as shown in hollow arrow, water inlet 341 can produce suction, anti-siphon rubber cushion 38 seals the hole on water diversion disk 37 under the effect of suction, its suction is reduced, simultaneously, air inlet below anti-siphon rubber cushion 38 starts supplementary air and goes to take up space, and makes it the water in water-closet tank must not be sucked in water inlet 341.Therefore, the peak level of water-closet tank must under air inlet, and this peak level is called critical groundwater table, referred to as CL.
Distance between the working water level (WL) of this backflow proof closestool water inlet valve and critical groundwater table (CL) is arranged by international standard.
As shown in Figure 4, this backflow proof closestool water inlet valve and existing water intaking valve unlike, spout hole is provided with between working water level (WL) and critical groundwater table (CL), if water inlet component 3 breaks down, water inlet can not stop, so, unnecessary water can flow into outer tube 2 from spout hole, and enter in toilet bowl sewage draining pipe by interior pipe 1, the water level that this overflow is formed just is called flood level, referred to as OL, flood level (OL), distance between working water level (WL) and critical groundwater table (CL) are also arranged by international standard.No matter how this backflow proof closestool water inlet valve adjusts, and flood level (OL), distance between working water level (WL) and critical groundwater table (CL) all can not change.Therefore, this backflow proof closestool water inlet valve can produce bowl water backflow phenomenon in no instance, thus ensure that the pure of tap water.
Above-described embodiment and graphic and non-limiting product form of the present utility model, style and position, the suitable change that any those skilled in the art does it, modification and change, all should be considered as being equal to mutually with technical characteristic of the present utility model.
