Abstract
The utility model provides a vacuum breaker, which comprises a valve body connected onto a water supplying pipeline, wherein a suction hole is arranged on the valve body, a guide rod is arranged in the suction hole, the upper end of the guide rod extends in the interior of the valve body, and a cover plate is arranged at the upper end of the guide rod. The utility model has the advantages that the structure is simple, the forming of vacuum in the water supplying pipeline can be eliminated automatically, and the syphonage and pollution in reflux can be effectively avoided.
Description
Technical field
The utility model relates to a kind of valve, particularly discloses a kind of vacuum breaker that is installed in the destruction vacuum on the water supply line, is applied to the domestic water supply valve.
Background technique
The residential building building, factory building, water supply network situation complexity in the occasions such as laboratory, and communicate with the main-supply net in city, and hydraulic pressure is not invariable in the pipe network, when situation such as the too much or local pipeline section emptying of water consumption occurring when part in the pipe network, can form negative pressure, the reverse siphon of flowing water that goes out in downstream is returned and is responsible in the net.The appearance of this situation is breakneck, because can not guarantee whether the water that refluxes is contaminated even toxic.Device that does not almost address this problem in the market or equipment.
Summary of the invention
The purpose of this utility model is to overcome problems of the prior art, provides a kind of simple in structure, can eliminate the formation of vacuum in the water supply line automatically, effectively prevents the vacuum breaker that the siphon backflow pollution takes place.
The utility model is achieved in that a kind of vacuum breaker, it is characterized in that: comprise the valve body that is connected on the water supply line, described valve body is provided with suction port, is provided with guide rod in the described suction port, valve inner is stretched in described guide rod upper end, and the upper end of described guide rod is provided with cover plate.
The upper end of described suction port is provided with seal ring, and described cover plate covers on seal ring.
The surface of described guide rod and cover plate is a smooth surface.
Described guide rod is vertical mutually with horizontal plane.
The utility model relies on the atmospheric pressure in the external environment condition, and when water supply line inside was negative pressure, external pressure backed down the cover plate that covers on the valve suction port, makes outside air enter pipeline, destroyed vacuum in the pipe.
The beneficial effects of the utility model are: can eliminate the formation of vacuum in the water supply line automatically, effectively prevent the generation of siphon backflow pollution.

Fig. 2 is the connection diagram of the utility model and water pipe.
Fig. 3 is the utility model guide rod and the cover plate configuration state figure during by jack-up.
Fig. 4 is the structural representation that the utility model embodiment one is connected with water pipe.
Among the figure: 1, valve body; 2, seal ring; 3, guide rod; 4, cover plate; 5, suction port; 6, water supply line; 7, hollow arrow; 8, filled arrows; 9, tee union.
Embodiment
According to Fig. 1~Fig. 4, the utility model comprises the valve body 1 that is connected on the water supply line 6, and described valve body 1 is provided with suction port 5, is provided with guide rod 3 in the described suction port 5, and valve body 1 inside is stretched in described guide rod 3 upper ends, and the upper end of described guide rod 3 is provided with cover plate 4.The upper end of described suction port 5 is provided with seal ring 2, and described cover plate 4 covers on seal ring 2.The surface of described guide rod 3 and cover plate 4 is a smooth surface.Described guide rod 3 is vertical mutually with horizontal plane.Hollow arrow 7 among Fig. 2 is the direction of current in the water supply line.Filled arrows 8 is the flow direction of cover plate 4 air during by jack-up among Fig. 3.
In Fig. 1~Fig. 3, described valve body 1 is the both ends open type, and the two ends of valve body 1 link to each other with water supply line 6 respectively.
Embodiment one: as Fig. 4, described valve body 1 is an end opening type, and valve body 1 links to each other all the other structures such as above-mentioned by tee union 9 with water supply line 6.
The utility model when mounted, guide rod 3 will guarantee horizontal by plumbness, could guarantee like this that cover plate 4 can fall with own wt to cover seal ring 2 when free state, prevents to leak.In any case the shape of described valve body 1 changes, the relative position relation of seal ring 2, guide rod 3, cover plate 4, suction port 5 immobilizes.
Claims (4)
1. vacuum breaker, it is characterized in that: comprise the valve body that is connected on the water supply line, described valve body is provided with suction port, is provided with guide rod in the described suction port, and valve inner is stretched in described guide rod upper end, and the upper end of described guide rod is provided with cover plate.
2. according to the described vacuum breaker of claim 1, it is characterized in that: the upper end of described suction port is provided with seal ring, and described cover plate covers on seal ring.
