Description

Footrest type valve

The utility model relates to automatic wash water control gear in a kind of public lavatory, specifically is a kind of valve with pin pier function.

Along with the construction and the development in city, at present, the groove type public lavatory is more and more, and the flushing device in this lavatory mainly is an automatic siphon formula water tank.No matter this kind water tank is someone or unmanned, is that the people people that still is few more, and always intermittent type is ceaselessly washed by water, if unattended, then day and night bath, water usage is very big, waste water more than 50%, if send someone management, though water consumption descends, but it is extremely inconvenient, also economical inadequately, in fact also be difficult to carry out, thereby, the water saving of groove type washroom does not have comparatively practical solution so far.

The purpose of this utility model is exactly a kind of water controller of using that designs at above-mentioned condition, and the gravity that utilizes people to stand in the pier position is controlled the water inlet of water tank, thereby reduces water usage, and without the personal management.

Solution of the present utility model is: have two waterways on housing, and by the 3rd water channel connection, in the 3rd water channel, be provided with valve body, in valve body, be equipped with by valve rod, flap, the valve that spring and valve gap constitute, the top and the bottom of flap are communicated with two water channels by water channel respectively, wherein valve rod stretch out beyond the valve body and with or contact with the other end that an end is movably articulated in the pedal on the housing by lever, the projection of placing restrictions on pedal position is arranged on housing, make pedal all the time with the horizontal tilt several angle, and allowable angle of inclination is not more than 10 °, and its detailed content is described below referring to accompanying drawing:

Referring to Fig. 1, Fig. 2, Footrest type valve of the present utility model, it is characterized in that on housing (1), having two waterways (14), (15), front and back have four mouths of a river, and be communicated with by the 3rd water channel (16), in the centre of the 3rd water channel (16) valve body (11) is housed, in valve body (11), be equipped with by valve rod (3), flap (7), the valve that spring (8) and valve gap (4) constitute, the top and the bottom of flap (7) are respectively by water channel (16) and (14), (15) water channel is communicated with, stretching out valve body (11) contacts in addition and with the other end that an end is movably articulated in the pedal (2) on the housing (1), or contact with pedal (2) by lever (12), as shown in Figure 3, when pedal (2) when rotating, direct actuate valve stem (3), or make flap (7) with valve open by shouldering bar (12) actuate valve stem (3), spring (8) resets flap (7), the projection (13) of placing restrictions on pedal (2) position is arranged on housing (1), make pedal (2) when rotating, as long as to the position of Danone actuate valve stem (3) with valve open, make pedal (2) all the time with horizontal plane inclination several angle, and the tilt angle is not more than 10 °, people are squatted to go up comfortable at pedal (2), during use, the utility model is placed on the stool crouching position in lavatory, as the pin pier, then with the city with running water pipe and tank inlet pipe respectively with water channel (14), (15) water intake of front connects, water channel (14), (15) water outlet of back is connected with the Footrest type valve door of next stage respectively by water pipe, and the like, the water outlet of the Footrest type valve of afterbody stops up, like this, when people's stool and urine, tramp with one's feet when the pedal (2) of Footrest type valve, the one side clean hygiene, make the people squat comfortablely, on the other hand under the effect of gravity, pedal (2) rotating drive valve rod (3) motion, flap (7) is opened door, water in the water channel that is connected with running water pipe (15) enters flap (7) top by water channel (16) and flows in the water channel (14) that is connected with water tank, and then inflow water tank, after the water level in the water tank reach a certain height, just flushing discharges water, after the people leaves pedal (2), flap (7) and valve rod (3) reset under spring (8) effect, again valve closing.The novel feature of this use is that also the bottom of valve rod (3) and flap (7) are connected as a single entity, both integrative-structures, simple in structure, flap pad (6) is arranged on the flap (7), during valve closing, be used for sealing the mouth of a river, pressure spring (8) is housed below, drive flap (7) and reset, throttle down has water-impervious filler (5) in valve gap (4) below on the top of valve rod (3), especially anti-sealing oozes out in valve body (11) upper end, water leakage phenomenon occurs, pedal of the present utility model (2) is apart from shape, and convenient and suitable people place pin and use.

The Footrest type valve that the utility model provides is to stand in inevitable action on the pier position when utilizing people's stool and urine to come Open valve and people just to finish closing automatically of valve when leaving away, set up the function relation that the water tank water intake amount is directly proportional with number of going to toilet and time, thereby solved the unmanned problem of using automatic shutoff of existing groove type washroom, avoided existing groove type washroom day and night to wash by water, the defect of invalid water, equipped lavatory of the present utility model, water usage can descend greatly, at least economize on water 50%, and according to the couchant stability of people, the pin pier and the horizontal plane inclination several angle of valve will be driven, make the people couchant comfortable, the utility model novel structure designs ingenious, and with practical value.
