Description

A kind of intelligent water-saving water-flushing device holds discharging valve

Technical field

The utility model relates to a kind of water-flushing device, especially relates to a kind of intelligent water-saving water-flushing device and holds discharging valve.

Background technology

At present, in the larger public lavatory of the utilization rate such as school, station, its bath facility adopts interval to discharge water more, no matter someone enters lavatory, toileting person counts number, and every the set time, water tank automatic draining flushing toilet bowl, this mode easily causes water resource waste.Chinese patent discloses a kind of water flushing device with cistern (notice of authorization number: CN 103556689 A), it comprises water inlet pipe, water tank, outlet pipe and squat type closet, one end of outlet pipe is communicated with water tank, the other end is communicated with described squat type closet, the connectivity part of outlet pipe and water tank arranges water valve, on water valve, connect a stay cord I, it is characterized in that: also comprise a point branching pipe, divide branching pipe one end to be communicated with water inlet pipe, the other end is communicated with squat type closet, divide on branching pipe branch's water valve is set, branch's water valve connects a stay cord II: described stay cord I and stay cord II are all affixed to one end of a lever, the other end of lever connects a stay cord III, branch's water valve comprises sleeve pipe and block, sleeve pipe one end is fixedly connected on point branching pipe, the other end is provided with pipe lid, in sleeve pipe, be provided with block, the upper end of the block pull bar that is connected, rod outer sleeve has Compress Spring, and pull bar stretches out with stay cord ll and is connected from the pipe lid of sleeve pipe, and the lower end of block penetrates in point branching pipe.But this water-flushing device need to be used the mechanical part such as stay cord, pull bar, service time one, length can run into the problems such as aging, and component of machine easily produces fault, thereby caused water-flushing device to use.

Utility model content

The utility model is to provide a kind of intelligent water-saving water-flushing device and holds discharging valve, it is mainly to solve the existing water-flushing device of prior art need to use the mechanical part such as stay cord, pull bar, service time one, length can run into the problems such as aging, component of machine easily produces fault, thus the technical problem that causes that water-flushing device cannot use etc.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of intelligent water-saving water-flushing device of the present utility model holds discharging valve, comprise casing, in described casing, be provided with the pipeline that expands into M shape, pipe ends is respectively equipped with water inlet, the lower mouth of a river, stretch out outside casing at the lower mouth of a river, two knees of M shape pipeline upper end be respectively equipped with gas stifled curved, drainage is curved, the stifled curved upper end of gas is connected with bleed ports, it is curved that a knee of M shape lower end of duct is provided with water blocking.By opening or close bleed ports, can control pipeline retaining or the draining of M shape, the whole discharging valve machinery-free that holds moves, and only can complete everything with air pressure, has therefore avoided mechanical part to produce fault.Airtight bleed ports, in casing when water filling, can carry out retaining in pipeline, water level by gas block up curved after, the part water yield can be fallen water blocking crook, after the whole water blocking of the curved water-stop of water blocking is curved, gas is stifled to be stooped end and water blocking bent up end just can to form a gas stifled.Continue after water filling, water blocking ponding increases and forms water column, and the height of water blocking ponding should not exceed the curved lower end of drainage, thereby reaches pressure balance.Open bleed ports, the stifled air of gas is discharged rapidly, and water can enter rapidly pipeline from water inlet, after siphon forms, can close bleed ports, and current can be discharged toilet flushing from the lower mouth of a river and be squatted over a pit to relieve oneself.Discharging water after necessary requirement, opening bleed ports and can cut off siphon, discharging water and can stop.

As preferably, stifled curved upper end height, lower end height upper end height, the lower end height curved with drainage of described gas equates, can ensure like this air pressure equilibrium, can ensure whole normal operation of holding discharging valve.

As preferably, described bleed ports is connected with control valve.Control valve can be controlled water yield, according to structure difference, the visitors flowrate in hole number and the height of hydraulic pressure set water yield (erosion quantity) 2.8 liters-5.3 liters.

Therefore, the utility model utilizes the pipeline of M type, opens or close bleed ports by control, the function that makes pipeline there is retaining and discharge water, and without mechanical action, application life is longer, is not easy to produce fault, simple and reasonable for structure.
