Description

Water flushing device of water saving type

Vent plug formula water-saving flush device belongs to the flushing in, the drainage plant, draining, gives water controller, it is applicable to the washroom of communal facilitys such as dwelling house, hotel, hotel, can be installed in simultaneously in the strong or poisonous environment of corrosivity in the chemical industry as one say flushing, feedwater, blowdown automatically and manual overvide.

Flusher commonly used at present mainly contains two kinds, and a kind of is pull-type siphon flusher, and following deficiency is arranged: it is longer that (1) forms the preceding overflow time of siphon, and this part water is reactive power consumption; (2) movable part is many, is out of order easily, must often keep in repair; (3) making water, what are wayward, all need one case water general at every turn; Relatively require great effort when (4) using, unhygienic.Another kind is the sealing-plug formula, though water-saving performance is arranged, owing to be the mechanical blockage formula, is out of order easily, and the seepage phenomenon is difficult for solving.

The purpose of this utility model be to provide a kind of can automatic control again can be manual, can rinse the vent plug formula water-saving flush device that water-saving result needn't often be keeped in repair significantly again well.

Major technique content of the present utility model is by preceding siphon chamber ［ 6 ］, middle siphon chamber ［ 7 ］, back siphon chamber ［ 8 ］, syphon ［ 9 ］, interface ［ 10 ］ is formed, siphon chamber ［ 6 ］ before it is characterized in that, middle siphon chamber ［ 7 ］ and siphon chamber, back ［ 8 ］ are to be fastenedly connected with connector ［ 4 ］ by loam cake ［ 3 ］ and lower cover ［ 11 ］ to form, each chamber that forms is annular, preceding siphon chamber ［ 6 ］ and top, middle siphon chamber ［ 7 ］ are communicated with, middle siphon chamber ［ 7 ］ and bottom, siphon chamber ［ 8 ］, back are communicated with, the top in back siphon chamber ［ 8 ］ is communicated with the upper end of syphon ［ 9 ］, the lower end of syphon ［ 9 ］ is communicated with interface ［ 10 ］, syphon ［ 9 ］ and interface ［ 10 ］ are one with lower cover ［ 11 ］ all, the position on the lower side of the chamber wall between middle siphon chamber ［ 7 ］ on the loam cake ［ 3 ］ and the siphon chamber, back ［ 8 ］, open control hole ［ 12 ］ when certain, a control cavity ［ 5 ］ is opened in preceding siphon chamber ［ 6 ］ on the loam cake ［ 3 ］ and middle siphon chamber ［ 7 ］ connection place, connects control cavity ［ 5 ］ and control valve ［ 1 ］ with control valve ［ 2 ］.

Control valve ［ 1 ］ is to be subjected to extraneous pressure open-minded, loses the device that extraneous pressure is closed, and when both opening, control valve ［ 2 ］ and control cavity ［ 5 ］ communicate with outside air, and control valve when closing ［ 2 ］ and control cavity ［ 5 ］ cut off with outside air.

The cross-sectional area of interface ［ 10 ］ is littler than the cross-sectional area of syphon ［ 9 ］.

Operating principle of the present utility model is as follows:

In the time of manually, after once flushing finishes, intake to water tank by the water tank water intake mechanism controls, water level stops after reaching corresponding height.Push switch valve during use, the air before making between siphon chamber and the middle siphon chamber is emitted under the pressure action of water, and begins to occur siphonage under the pressure action of water, after siphonage begins, the trip switch valve, the water in the water tank is until till having put like this; If desire to make the siphonage Halfway Stopping, during the upper end of the chamber wall before cistern water level is lower than between siphon chamber and the middle siphon chamber, the Push switch valve makes air enter into preceding siphon chamber and siphon chamber connection place again, and siphonage stops; If water supply volume more after a little while, the Push switch valve does not unclamp always, can make water level reduce to the upper end of the chamber wall between preceding siphon chamber and the middle siphon chamber like this; When controlling automatically, when cistern water level being reach a certain height by the water inlet of water tank water intake mechanism, because the pressure action of water, air siphon chamber after the timing controlled hole is pressed into before making between siphon chamber and the middle siphon chamber, thereby formation siphonage, after current in the water tank are intact, repeat said process automatically.

Advantage of the present utility model is that cost is low, and is easy to installation and maintenance because movable part is few, and manufacturing process is simple; Owing to adopt vent plug to block water, so the leakproof phenomenon; Can manually control, also can control automatically, and reach the purpose of water saving; Control flexible, convenient, healthy, laborsaving.

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

Fig. 2, Fig. 3, Fig. 4 be respectively when manually controlling by brake control valve, the state diagram when siphonic process and current are intact.

Fig. 5 is the state diagram of interrupting siphonage when manually controlling by brake control valve;

Fig. 6 and Fig. 7 are that the siphonage of automatic control process begins with current the state diagram when intact.

Now provide embodiment of the present utility model as follows in conjunction with the accompanying drawings:

The utility model as shown in Figure 1, by control valve ［ 1 ］, control valve ［ 2 ］, loam cake ［ 3 ］, connector ［ 4 ］, lower cover ［ 11 ］, syphon ［ 9 ］, interface compositions such as ［ 10 ］, wherein, loam cake ［ 3 ］ and lower cover ［ 11 ］ are fastenedly connected with connector ［ 4 ］, siphon chamber ［ 6 ］ before forming, middle siphon chamber ［ 7 ］, back siphon chamber ［ 8 ］, each chamber that forms is annular, preceding siphon chamber ［ 6 ］ and top, middle siphon chamber ［ 7 ］ are communicated with, middle siphon chamber ［ 7 ］ and bottom, siphon chamber ［ 8 ］, back are communicated with, the top in back siphon chamber ［ 8 ］ is communicated with the upper end of syphon ［ 9 ］, the lower end of syphon ［ 9 ］ is communicated with interface ［ 10 ］, syphon ［ 9 ］ and interface ［ 10 ］ are one with lower cover ［ 11 ］ all, the position on the lower side of the chamber wall between middle siphon chamber ［ 7 ］ and the siphon chamber, back ［ 8 ］, open control hole ［ 12 ］ when certain, a control cavity ［ 5 ］ is opened in preceding siphon chamber ［ 6 ］ on the loam cake ［ 3 ］ and middle siphon chamber ［ 7 ］ connection place, connects control cavity ［ 5 ］ and control valve ［ 1 ］ with control valve ［ 2 ］.

Control valve ［ 1 ］ is to be subjected to extraneous pressure open-minded, lose the device that extraneous pressure is closed, both do not had when logical, control valve ［ 2 ］ and control cavity ［ 5 ］ communicate with outside air, control valve when closing ［ 2 ］ and control cavity ［ 5 ］ cut off with outside air, can adopt as the form among Fig. 1.

Form such as connector ［ 4 ］ can adopt bolt, rivet, be threaded.

When use installing, interface of the present utility model ［ 10 ］ and the delivery port of water tank bottom can not had leakage and be connected and get final product.
