Abstract
The utility model an opening and closing device for the water valve of water drinking machine, comprising a valve cover, a handle, a spring, a connecting rod, a conical valve, a combined part which is connected with the machine body of a water drinking machine and the valve body of a conical valve seat. The opening and closing device is characterized in that the conical surface of the conical valve is provided with at least one convex ring, a bowl which is provided with a connecting flange is arranged on the connection end of the conical valve and the connecting rod, and the connecting flange of the bowl is tightly pressed on the flange of the valve body by the valve cover.
Description
The utility model is about drinking machine, particularly about the opening and closing device of drinking machine water valve.
The drinking machine water valve generally adopts the opening and closing device of lever lifting type at present.It is by pushing or upwards move the handle of the valve gap outside that is arranged on the valve body downwards, makes an end hinged with it and connect the connecting rod that valve gap extend in the valve pocket of valve body and upwards promote.When connecting rod upwards promoted, the spring of wedging ring on connecting rod shank drove the valve that connects with the connecting rod the other end on the one hand and moves upward on the one hand, valve lifted off a seat, thereby open water valve.When decontroling handle, connecting rod drives valve and moves downward together under the counter-force effect of spring, until valve with till valve seat contacts, thereby water valve is closed.At this moment, handle also sets back.The water valve opening and closing device of this lever lifting type has advantage simple to operate, that opening force is little.For preventing that water valve from leaking, adopt conical valve and valve seat usually.So.Just produced a problem, because the positive pressure between the opening and closing device valve of lever lifting type and the valve seat is limited by spring force, so require the valve of taper and valve seat that good form fit is arranged, this just means the rising of manufacture cost.And service time one is long, the destruction that causes form fit between conical valve and the valve seat easily, and generation is leaked.Secondly, connecting rod passes through the valve gap part and adopts packing seal, resistance not only greatly, but also need often to regulate the pressure and the periodic replacement filler of filler, increased maintenance load and expense.
The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, keeps the drinking machine water valve opening and closing device of the existing advantage that lever lifting type opening and closing device is simple to operate, opening force is little again.
The purpose of this utility model is achieved in that a kind of drinking machine water valve opening and closing device, it comprises valve gap, handle, spring, connecting rod, conical valve and is provided with the bound fraction that links to each other with the drinking machine body and the valve body of conical valve seat, it is characterized in that being provided with at least on the conical surface of described conical valve the ring of a projection; An end that is connected with connecting rod at above-mentioned conical valve is provided with the bowl of being with adpting flange, and the adpting flange of above-mentioned bowl is pressed on the flange of valve body by valve gap.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is general structure signal of the present utility model.
Fig. 2 is the structural representation of the utility model when opening.
The utility model as shown in Figure 1, it comprises handle 1, connecting rod 2, conical valve 7, spring 14, valve gap 15 and valve body 12.Valve body 12 1 ends are the bound fraction 11 that links to each other with the drinking machine body, and the other end is provided with valve pocket 5 and conical valve seat 9.Valve pocket 5 links to each other with the liquid receiver of drinking machine by the water liquid path 10 that is arranged on the valve body 12.Conical valve seat 9 one ends communicate with valve pocket 5, and the other end communicates with water outlet 8 on being arranged on valve body 12.Valve gap 15 is positioned at the top of valve pocket 5, links to each other with valve body 12 with screw thread.Conical valve 7 is positioned at valve pocket 5, is provided with the ring 6 of a projection on itself and the conical valve seat 9 corresponding conical surfaces at least; Two rings 6 at a distance from each other preferably are set.The other end of conical valve 7 is connected with an end of the connecting rod 2 that stretches into valve gap 15, and the bowl 4 of band adpting flange 3 is set.Above-mentioned adpting flange 3 is pressed on the flange of valve body 12 by valve gap 15, thereby valve pocket 5 is led to the passage sealing of valve gap 15, thus make formed between valve gap 15 and the valve body 12 one with the not connected cavity 13 of valve pocket 5.The other end that connecting rod 2 stretches out valve gap 15 is hinged with the handle 1 that is positioned on the valve gap 15 top end faces.Spring 14 is enclosed within on the shaft of the connecting rod 2 that is positioned at cavity 13, and its two ends are bearing in respectively on the corresponding supporting surface of valve gap 15 and connecting rod 2.Ring 6 is because its surface area is little, so can form good close applying with conical valve seat 9 under the elastic force of spring 14.If the material of ring 6 has the certain elastic deformation ability, then Mi Feng effect is desirable especially.Fig. 2 is that the utility model is in the situation when opening, handle 1 is upwards moved (also can push) downwards, handle 1 is around its instantaneous rotation, connecting rod 2 is upwards promoted, thereby driving awl meter valve 7 moves upward together, make ring 6 leave conical valve seat 9, water valve is opened, and potable water flows out from water outlet 8.This moment, bowl 4 was in deformation state, and the degree of its distortion is directly proportional with the aperture of conical valve.The distortion of bowl 4 for the benefit of can be provided with the retractable puckered ring of several similar Accordion bellows thereon.
The utility model has changed the contacted conventional seals mode of the whole conical surface between the conical valve and conical valve seat in the past, only utilize and form narrow continuous seal band between protruding ring 6 and the conical valve seat 9, and under certain spring force, have bigger positive pressure, admittedly can reach effective seal.Adding conical valve 7 employings has certain flexible material, and then its effect is better.Bowl material 4 is isolated with the space at valve gap 15 and connecting rod 2 places effectively with valve pocket 5 simultaneously, fills out lining so need not to be provided with the big sealing of resistance between connecting rod 2 and the valve gap 15 again.So that the utility model is not only operated is more laborsaving, easily manufactured, cost reduces but also need not to change stuffing box packing, has simplified maintenance, reduced maintenance expenses.
