Abstract

The utility model provides a novel valve which is used when opening and closed when leaving. The novel valve comprises a valve body, a valve core and a valve rod, wherein, the valve body is provided with a hollow liquid channel which comprises a water inlet and a water outlet, the valve core is arranged on the liquid channel and is used for opening or shutting off the liquid channel, one end of the valve rod is connected with the valve core in a transmission way, the other end of the valve rod extends to the outer side of the valve body, a fixed seat is arranged on the valve body, an outer-side protection layer at one end of a brake line is arranged on the fixed seat, a steel wire of the brake line is connected with the valve rod positioned at the outer side of the valve body, the outer-side part of the valve body of which the valve rod is arranged is provided with a reset spring that is used for leading the valve rod to reset and the other end of the brake line is connected with a pedal switch which is used for driving the valve rod to swing, so as to control the opening or the shut-off of the liquid channel further. The novel valve is used for public occasions, such as schools, hospitals and theatres and so on for avoiding the situations that the people forget closing the valve or the people are reluctant to close the valve because of sanitary aspects, thereby preventing the waste of the water resources.

Description

A kind of novel valve

Technical field

The utility model relates to a kind of novel valve, and it is located at and is used for opening or turn-offing fluid passage on the pipeline.

Background technique

Valve has been known, it generally comprises the valve body that offers fluid passage, is located at spool and valve rod in the valve body, described valve rod one end is located in the valve body and with spool and is in transmission connection, and the valve rod the other end extends to the valve body outside and is used for being connected with hand-operating device such as rotatable handle.Because valve core structure is different, its motion mode of the valve rod that is connected with spool is also different, the valve rod that has moves up and down with respect to valve body by screw-thread fit and realizes opening or turn-offing fluid passage, the valve rod that has then is to spend to rotate by 90 degree or 180 to realize opening or turn-offing fluid passage, and the valve rod that has then is the unlatching of the terminal swing realization of employing fluid passage or closes.When aforementioned known valve is used for public arena such as school, hospital, Movie theater and entertainment places, often occurs that people forget closing valve or be reluctant to contact again the valve rod of valve for considering of health aspect, thereby cause the huge waste of water resources.

The model utility content

The purpose of this utility model is to provide a kind of and instantly opens, with walking with the novel valve that closes.

The technological scheme that the utility model adopted is such: a kind of novel valve; comprise valve body; spool and valve rod; described valve body is provided with the hollow liquid passage that comprises water intake and water outlet; described spool is located at and is used for opening or turn-offing described fluid passage on the fluid passage; described valve rod one end and spool are in transmission connection; the other end of valve rod extends to the valve body outside; described valve body is provided with a fixed base; the outside protective layer of one braking string, one end is located on this fixed base; the steel wire of braking string is connected with the valve rod that is positioned at the valve body outside; described valve rod is positioned at the valve body external lateral portion and is provided with and is used to Returnning spring that valve rod is resetted, and the other end of braking string is connected to unlatching or the shutoff that foot switch is used to drive valve rod swing and then controlling liquid passage.

Above-mentioned novel valve, described foot switch comprise cover plate and the base plate that a side is hinged, and described plate upper surface middle part is hinged with the knuckle support, and knuckle support one end is connected with the steel wire of braking string, and the knuckle support the other end is positioned near the cover plate lower surface.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the unlatching of fluid passage or shutoff can realize by foot switch, get final product water outlet as long as step on foot switch during water like this, a very important person leaves then that fluid passage automatically shuts down in the time of no under the effect of Returnning spring, avoid people to forget closing valve or because health aspect former thereby be reluctant that the situation of closing valve occurs, thereby prevent the waste of water resources.

Embodiment

With reference to figure 1; Fig. 2; embodiment discloses a kind of novel valve; it comprises valve body 1; the spool (not shown); valve rod 2; braking string 3; foot switch 4 and Returnning spring 5; described valve body 1 inboard is provided with the fluid passage of hollow; the two ends of fluid passage are positioned at valve body 1 external lateral portion and are respectively equipped with water intake 11 and water outlet 12; described spool is located at and is used for opening or turn-offing described fluid passage on the fluid passage; described valve rod 2 one ends and spool are in transmission connection; the other end of valve rod 2 extends to valve body 1 outside; described valve body 1 is provided with a fixed base 13; the outside protective layer 31 of braking string 3 one ends is located on this fixed base 13; the steel wire 32 of braking string 3 is connected with the valve rod 2 that is positioned at valve body 1 outside; described valve rod 2 is positioned at valve body 1 external lateral portion and steel wire 32 those relative sides and is provided with and is used to Returnning spring 5 that valve rod 2 is resetted; described Returnning spring 5 the other ends are located near the bottom of valve body 1; described foot switch 4 comprises hinged cover plate of a side 41 and base plate 42; described base plate 42 upper surface middle part are hinged with knuckle support 43; knuckle support 43 1 ends 431 are connected with the steel wire 34 of braking string 3 the other ends; knuckle support 43 the other ends 432 are positioned near cover plate 41 lower surfaces, and the outside protective layer 33 of braking string 3 the other ends is located at the cover plate 41 and the base plate 42 hinge portions outside.When above-mentioned novel valve is located at the water pipe end and is used for the public arena, as long as with foot-operated foot switch 4 down, knuckle support 43 turns clockwise under cover plate 41 effects and drives steel wire 34, because the transmission of brake steel wire, thereby steel wire 32 drives the fluid passage in the certain angle unlatching valve body 1 of valve rod 2 swings, and the liquid in the pipeline is able to flow out by spool and from pipe end.Directly leave after water finishes, under the effect of Returnning spring 5, valve rod 2 is reset to initial position, and fluid passage turn-offs, and really realizes instant opening, with walking with the energy-conservation purpose of closing.

In the foregoing description, Returnning spring one end that is used to valve rod is resetted is located at valve rod, the other end can be located at and also can be located on the valve body on the another one support that is fixed on the valve body or on specific installation occasion is fixed in other fixture except that valve body, as long as provide a fixing force bearing point to Returnning spring, described foot switch provides the function of a similar brake handgrip, and it is used for the steel wire in setting stroke in-draw braking string.Any some suitable foot-operated structures of swing arm or bar bar structure that comprise all can be used as foot switch and can realize the purpose of this utility model.
