Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model negative pressure inhibition device;
Structural representation when Fig. 2 is the utility model negative pressure inhibition device work when producing negative pressure in water pipe.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1 and Fig. 2, a kind of negative pressure inhibition device, comprises and body 1, and the lower end of body 1 is provided with water inlet 8, enters body 1 for the tap water in system.
Be provided with sliding bucket 2 in body 1, in sliding bucket 2, be provided with the large ball float 3 that can fluctuate therein.
An enclosed area 11 is defined between sliding bucket 2 outer wall and body 1 inwall, enclosed area 11 is not directly communicated with body 1 with sliding bucket 2, the sidewall of enclosed area 11 is provided with air inlet port 4, the small floating ball 5 can blocking air inlet port 4 is provided with in enclosed area 11, the diameter of small floating ball 5 is greater than the width of air inlet port 4, is connected between large ball float 3 and small floating ball 5 by attachment 10.
Enclosed area 11 and sliding bucket 2 have one section of bucket wall 21, and this barrel of wall 21 is in fact also one section that slides bucket 2 sidewall.Bucket wall 21 is provided with a dodge gate that can open and close 12, is with himself lower end for fulcrum when dodge gate 12 opens and closes, and realizes by rotation after External Force Acting, and the interlude of attachment 10 passes dodge gate 12 and is connected with dodge gate 12.
Perforation is provided with, for water-through and ventilating with sidewall bottom sliding bucket 2.Certain bucket wall 21 is not bored a hole, and bucket wall 21 is also a part for sliding bucket 2 sidewall.
The inwall of air inlet port 4 is provided with some layers of sealing ring 6, and sealing ring 6 can play sealing function, makes better tightness between small floating ball 5 and air inlet port 4, can not leak gas.
Be connected by spring 7 between small floating ball 5 with air inlet port 4, under elastic force effect, small floating ball 5 can be allowed to block air inlet port under normal circumstances.
The lower end of enclosed area 11 is one is from inside to outside downward-sloping gripper shoe 9, and the lower end of gripper shoe 9 connects with the lower end of air inlet port 4 and flushes, and being obliquely installed is be conducive to small floating ball 5 to move to air inlet port 4 direction under gravity and elastic force effect.
Attachment 10 is elastomeric material attachment.The weight of large ball float 3 is greater than the weight of small floating ball 5, like this when large ball float 3 moves down, enough pulling force can be had to pull dodge gate 12 to open, and small floating ball 5 also will be pulled to move simultaneously.
Dodge gate 12 top is provided with sealant, and sealant can be the sealing ring mentioned in this patent, and in order to when dodge gate 12 is closed, between enclosed area 11 and sliding bucket 2, stuffiness is water-tight.
During use, water inlet 8 is fixed on the flow compensator between water supply pipe and supply equipment, tap water flows in body 1 by water inlet 8, and except enclosed area 11, water is full of body 1 and sliding bucket 2.Under buoyancy of water, large ball float 3 floats, and under the effect of spring 7, simultaneously because gripper shoe 9 is downward-sloping, small floating ball 5 can move and fitted seal circle 6 towards air inlet port 4, is blocked by air inlet port 4, does not have gas to enter enclosed area 11.Simultaneously in small floating ball 5 moving process, there is individual pulling function by attachment 10 pairs of dodge gates 12, dodge gate 12 is closed, and also can promote dodge gate 12 when ball float 3 rises to certain altitude greatly and close.
Continue shown in composition graphs 2, when a large amount of water causes hydraulic pressure decline in water pipe, body 1 middle water level declines, large ball float 3 sinks, when after sinking certain distance, dodge gate 12 is pulled open under the pulling of attachment 10, the movement of dodge gate 12 simultaneously can pull small floating ball 5 to move inward, now air inlet port 4 is opened, enclosed area 11 also communicates with in body 1, extraneous air is entered in body 1, compensates the negative pressure because water level decreasing causes in body 1, maintain the barotropic state in body 1, guarantee can not produce negative pressure in pipeline.
Air inlet port 4 is arranged on the side of body 1, and the impurity such as dust or rainwater can not flow into and pollute tap water, ensure that the water safety of user.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
