Abstract
The utility model discloses a siphon preventing device which is characterized by successively comprising a siphon preventing cone-shaped rubber ring, a siphon preventing cone-shaped sleeve, an O-shaped ring, a water core sealing assembly, a spring and a siphon preventing main body, wherein the siphon preventing cone-shaped rubber ring is sleeved inside the siphon preventing cone-shaped sleeve. The water core sealing assembly and the siphon preventing cone-shaped sleeve are fixedly connected into a whole through the O-shaped ring and are embedded into the siphon preventing main body, and the spring is further sleeved on the lower portion of the water core sealing assembly. The siphon preventing device is simple in structure, can effectively prevent backflow of sewage, and can eliminate negative pressure of pipelines.
Description
Technical field
The utility model relates to a kind of anti-siphon means.
Background technique
In recent years, news media's report is often arranged, what the tap water of so-and-so residential quarter flowed out is blue water, phenomenons such as the tap water that flows out is flavoursome, its reason are that anti-siphon means is being produced, do not installed on request when installing in various types of flushing valve, and anti-siphon means structure on the market is comparatively complicated simultaneously, effect is more not remarkable, cause the cost height, the poor phenomenon that takes effect, thus caused the user to be unwilling to install, buy.The mode of traditional anti-siphon means employing non-return occurs when pipeline under the situation of negative pressure specifically, the negative pressure in the pipeline can not be removed, so effect is relatively poor.
The model utility content
The utility model is at the disappearance of prior art existence, and its main purpose provides a kind of anti-siphon means, and it has simple in structure, can effectively prevent sewage backflow, the formation that can remove pipe negative pressure simultaneously.
For achieving the above object, the utility model adopts following technological scheme: a kind of anti-siphon means, it is characterized in that: comprise anti-siphon cone rubber circle, anti-siphon taper sheath, O type circle, water shutoff core assembly, spring and anti-siphon main body successively, described anti-siphon cone rubber snare is gone in the described anti-siphon taper sheath; Described water shutoff core assembly is one by above-mentioned O type circle and described anti-siphon taper sheath Joint then, and is nested in the anti-siphon main body, and above-mentioned water shutoff core assembly bottom also is arranged with above-mentioned spring.
After the utility model adopts technique scheme, its beneficial effect is: the following waterexit end that this anti-siphon means is installed in flushing valve, when flushing valve is washed by water, water flows to anti-siphon means from following waterexit end, by anti-siphon cone rubber circle, and limited the large deformation of rising of anti-Hong Zhuixingxiangjiaoquan with anti-siphon taper sheath, and play the effect of sealing, use water to flow out anti-siphon means; When flushing valve in off position, the water shutoff core assembly closely cooperates by elastic reaction and the anti-siphon cone rubber circle of spring, when negative pressure appears in water supply line, then by the water shutoff core assembly sewage and anti-siphon taper sheath are isolated, prevent sewage backflow to pipeline thereby play, play the effect of anti-siphon.Occur under the situation of negative pressure at water supply line in addition, the window that air can reach anti-siphon taper sheath both sides by the window that open anti-siphon main body both sides is back in the pipeline, pipeline is played the effect of decompression.
Description of drawings
Fig. 1 is perspective exploded view of the present utility model.
Embodiment
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment: be illustrated in figure 1 as a kind of anti-siphon means of the present utility model, it is characterized in that: comprise anti-siphon cone rubber circle 1, anti-siphon taper sheath 2, O type circle 3, water shutoff core assembly 4, spring 5 and anti-siphon main body 6 successively, described anti-siphon cone rubber circle 1 is inserted in the described anti-siphon taper sheath 2; 4 of described water shutoff core assemblies are one by above-mentioned O type circle 3 with described anti-siphon taper sheath 2 Joints, and are nested in the anti-siphon main body 6, and above-mentioned water shutoff core assembly 4 bottoms also are arranged with above-mentioned spring 5.
Of the present utility model focusing on, this anti-siphon means is installed in the following waterexit end of flushing valve, when flushing valve is washed by water, water flows to anti-siphon means from following waterexit end, by anti-siphon cone rubber circle 1, and limited the large deformation of rising of anti-siphon cone rubber circle 1 with anti-siphon taper sheath 2, and play the effect of sealing, use water to flow out anti-siphon means; When flushing valve in off position, water shutoff core assembly 4 closely cooperates by elastic reaction and the anti-siphon cone rubber circle 1 of spring 5, when negative pressure appears in water supply line, then by water shutoff core assembly 4 sewage and anti-siphon taper sheath 2 are isolated, prevent sewage backflow to pipeline thereby play, play the effect of anti-siphon.Occur under the situation of negative pressure at water supply line in addition, the window that air can reach anti-siphon taper sheath 2 both sides by the window that open anti-siphon main body 6 both sides is back in the pipeline, pipeline is played the effect of decompression.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
Claims (1)
1. an anti-siphon means is characterized in that: comprise successively and prevent siphon cone rubber circle, anti-siphon taper sheath, O type circle, water shutoff core assembly, spring and prevent the siphon main body that described anti-siphon cone rubber snare is gone in the described anti-siphon taper sheath; Described water shutoff core assembly is one by above-mentioned O type circle and described anti-siphon taper sheath Joint then, and is nested in the anti-siphon main body, and above-mentioned water shutoff core assembly bottom also is arranged with above-mentioned spring.
