Abstract

The utility model relates to a single siphon timing flushing water tank which is a water saving device used to timing flush a urinal channel (urinal). The utility model is characterized in that the utility model is composed of a water tank (1), a single siphon pipe (2), a quantitative adjustable water valve (3), and a water intake noise suppression hose (4). The flowrate of the quantitative adjustable water valve is regulated to control the flushing period. When the water level is higher than the top of the single siphon pipe, siphonage is generated to carry out flushing. The utility model can be used to solve a problem that overlarge water is used for continuously flushing a urinal channel (urinal), and can be used to enhance the flushing strength. The utility model has the advantages of obvious water saving, high flushing strength, simple manufacture process and structure, low cost, reliable operation, and convenient installation.

Description

Single siphon timing flushing water tank

The utility model belongs to feedwater, a kind of trough urinal (device) water saving fixtures of draining specialty.

In public building, the general process of washing continuously that adopts directly of trough urinal (device), under design discharge, a year water consumption can reach 3000～5000 tons, is ten times (according to water meter statistics) of a lavatory pan water consumption, and water resource is caused very big waste.Prior art such as automatic flush valve and Chinese patent CN87 2 14983U lavatory automatic flushing devices have solved automatic washing problems at present, the advantage than continuous flushing water-saving is arranged, but also have following shortcoming.Chinese patent CN87 2 14983U lavatory automatic flushing devices: be that structure and manufacturing process are complicated the first,, it is made up of 21 other parts, and each transmission mechanism must reach certain precision and could guarantee to use reliable.So to the manufacture process requirement height.The second, the turnover plate type discharging valve adopts gravity to fall after rise, and flat seal is selected precision, fineness, geometric shape, the material of valve port after the moulding like this, all requires very tight.And also to drive other mechanism when falling after rise and reset, be difficult to like this guarantee to seal tightly do not leak.Present most water tank all has discharging valve the plug formula to change hydrocone type into by gravity.Three, because trough urinal user position is only fixing, so adopt the Pedal-operated inconvenience.

Automatic flush valve: the first, manufacturing process complexity, cost height.Automatic flush valve valve body up and down uses brass casting, and process for machining, water inlet pipe use copper pipe to simmer system, and Rubber Diaphragm Seal is arranged between valve body up and down.Eight screws connect, thus its complex structure, the cost height.The second, operational reliability is poor, and the upper valve body inlet opening has only 2～3 millimeters, easily stops up.Valve body is connected with locknut with water tank, easily leaks, and as the problems referred to above take place, automatic valve can not wash automatically.Three, flow of inlet water is wayward.Automatic flush valve adopts common valve control flow of inlet water, regulates difficulty, is difficult to accomplish regularly accurately.If flushing cycle is too short, then do not reach the purpose of water saving.Because above shortcoming, above-mentioned technology are difficult to promote.

The purpose of this utility model is the deficiency at prior art, and provide a kind of, single siphon is wc flushing cistern regularly, it can reach desirable energy-saving effect.

The purpose of this utility model is to realize like this.This device is by water tank, single syphon, quantitatively finely tune water-supply valve, and water inlet noise elimination flexible pipe is formed.With single syphon of 20 millimeters of φ 10～φ, replace automatic flush valve, water-supply valve constantly supplies water, when water level is higher than the syphon top, promptly produces siphon and wash, the flushing cycle of this device, with quantitative fine setting water-supply valve control, regulating valve stem can change flow of inlet water, adjusts flushing cycle.

Concrete structure of the present utility model is provided by the following drawings:

Fig. 1 is according to the single siphon that the utility model proposes sectional drawing of flusher regularly, and this device comprises that the single syphon of water tank (1) (2) quantitatively finely tunes water-supply valve (3) water inlet noise elimination flexible pipe (4).

During this device work, the quantitative fine setting water-supply valve (3) of adjusting flushing cycle is to water tank (1) Nei Jiashui, and water inlet is added to water below the water surface by noise elimination flexible pipe (4), can reduce noise like this, when water level is higher than single syphon (2) pipe top, produces siphon and wash.

Fig. 2 is the sectional drawing that Fig. 1 quantitatively finely tunes water-supply valve, and this valve is made up of locking nut (5) valve rod (6) valve body (7).Valve rod (6) is finely tuned, can adjust the relative position of tapered valve core and valve body (7).Change flow of inlet water, reach desirable flushing cycle, after mixing up, locking nut (5) compresses, with the fixed-site of valve rod (6), in order to avoid flow of inlet water changes.

The utility model list siphon regularly flusher has following advantage:

1. water-saving result is obvious, generally can economize on water 80% than continuous flushing, and increases backwash rate.

2. simple in structure, cost is low, easy installation.The utility model has only three parts welderings to be one, directly installs, and cost has only 1/10 of automatic valve.

3. the utility model list siphon caliber is big, is difficult for stopping up.Casing and the welding of single syphon.Solved time mouth of a river seepy question, can move reliably continuously.

4. adopt the special-purpose quantitatively fine setting water-supply valve of design voluntarily, can finely tune flow of inlet water, accurately adjust flushing cycle, after mixing up locking nut is compressed, flow is difficult for changing, and adopts water supply hose to lead under water, has reduced the water inlet noise.

This shows,, still achieve the above object though the utility model is simple.

Claims

1, a kind of single siphon timing wc flushing cistern is the water saving fixtures of a kind of timing flushing trough urinal (device), it is characterized in that: it is quantitatively finely tuned water-supply valve (3) water inlet noise elimination flexible pipe (4) by the single syphon of water tank (1) (2) and forms.

2, flusher according to claim 1 is characterized in that: quantitatively finely tune water-supply valve (3) and be made up of locking nut (5) valve rod (6) valve body (7).
