Abstract
The utility model discloses a from pressure switch hydrant, characterized by opens on the outer wall of the bolt body of its inlet and the crossing connection of liquid outlet has the control mouth that has the ring flange, the bowl form valve that useful elastic material made is located to the seat on the ring flange, the bowl form disk seat falls on the water inlet, the upside of bowl form valve is provided with the apron and fixes a position it and bowl form valve on the ring flange through positioning bolt, it has little inlet to open in the bottom of bowl form valve, it has little liquid outlet and is linked together through the pipeline that is provided with little control valve and bolt body liquid outlet to open on the apron, and is simple in structure, and easy to operate, long service life, the characteristics that sealing performance is good.
Description
The utility model relates to a kind of hydrant, and is especially a kind of from compressing switch hydrant.
At present, making in the society and use in hydrant many kinds are arranged, but the technical scheme that mostly adopts spiral lifting or landing flashboard realizes, though the hydrant of this structure can be realized its task, but have following defective: the one, the making required precision strictness of its screw pair component and flashboard, sluice gate, so its manufacturing cost height; The 2nd, in use easily cause wearing and tearing or corrosion to damage between each component, be subjected to certain limitation its application life; The 3rd, bigbore hydrant operation effort is maybe needed to be equipped with the power set that control is closed or closed.
Task of the present utility model is to provide a kind of simple in structure, low cost of manufacture, easy operating, long service life, good seal performance, need not to be equipped with power set, especially adapts to the hydrant that compresses switch certainly in large flow pipe road.
Task of the present utility model takes following technical scheme to realize.Intersect on the key that is connected at inlet and one or more liquid outlet and be positioned on the key outer wall of inlet upside and have the control mouth that has flange, be located in the bowl-shape valve that useful elastomeric material is made on the flange in this control mouth, the base part seat of bowl-shape valve drops on the upper port of the water inlet in the key inner chamber, be provided with cover plate and by positioning bolt this cover plate and bowl-shape valve be positioned on the flange in the control mouthful at the upside of bowl-shape valve, have the little inlet that is connected with inlet on the key in the bottom of bowl-shape valve, on the cover board have with the little liquid outlet of the intracavity inter-connection of bowl-shape valve and the pipeline by being provided with little control valve and be connected with liquid outlet on the key.
According to such scheme, when needs are opened hydrant, little control valve is opened, ducted liquid entered inlet and promote the upper port that bowl-shape valve breaks away from inlet under the effect of fluid pressure this moment, making liquid enter liquid outlet flows out, liquid in the inlet flows out after little inlet enters in the bowl-shape valve and enters liquid outlet by the road simultaneously, thereby realizes opening the task of hydrant.When needs are closed hydrant, little control valve is closed, the liquid that enter in the bowl-shape valve this moment flows out no longer by the road, when liquid is full of bowl-shape valve insertion, when fluid pressure equates with fluid pressure in the inlet in its bowl-shape valve insertion, bowl-shape valve port will be located on the inlet, thus sealing inlet and realize closing the task of hydrant.Owing to taked technique scheme, the utlity model has following evident characteristic: the one, owing to adopted the technical scheme of little control valve control hydrant switch, so have easy operating, need not to be equipped with power set, and adaptation is to the manual control hydrant on large flow pipe road; The 2nd, owing to adopted the technical scheme of the bowl-shape valve port of elasticity, existing all kinds of employing spirals promote or the technical scheme of landing flashboard has characteristics simple in structure, low cost of manufacture; The 3rd, because valve port has adopted soft compounding technique scheme, so have good seal performance, long service life and characteristics for ease of maintenaince.Can effectively realize task of the present utility model in sum.
Below will be with reference to the accompanying drawings that the utility model is described in further detail is as follows.
Accompanying drawing has provided the structural representation of the hydrant that compresses switch certainly that the utlity model has two liquid outlets.
In the accompanying drawings, 1 be inlet, 2 and 11 for liquid outlet, 3 for bowl-shape valve, 4 for flange, 5 for positioning bolt, 6 for cover plate, 7 for little liquid outlet, 8 for little control valve, 9 for pipeline, 10 for control mouthful, 12 for little inlet.
With reference to the accompanying drawings, intersect on the keys that are connected and be positioned on the key outer wall of inlet 1 upside at inlet 1 and liquid outlet 2 and 11 and have the control mouth 10 that has flange 4, on flange 4, be located in the bowl-shape valve 3 that useful elastomeric material is made, the base part seat of bowl-shape valve 3 drops on the upper port of the water inlet 1 in the key inner chamber, be provided with cover plate 6 and this cover plate 6 and bowl-shape valve 3 be positioned on the flange 4 at the upside of bowl-shape valve 3 by positioning bolt 5, have the little inlet 12 that is connected with inlet 1 in the bottom of bowl-shape valve 3, be connected with liquid outlet 11 on the key having on the cover plate 6 with the little liquid outlet 7 of the intracavity inter-connection of bowl-shape valve 3 and the pipeline 9 by being provided with little control valve 8.
Claims (2)
1, a kind of from compressing switch hydrant, comprise cover plate and the key of forming by liquid outlet and inlet, it is characterized in that intersecting on the key that is connected and being positioned on the key outer wall of inlet upside having the control mouth that has flange at its inlet and liquid outlet, be located in the bowl-shape valve that useful elastomeric material is made on the flange in this control mouth, the base part seat of bowl-shape valve drops on the upper port of the water inlet in the key inner chamber, be provided with cover plate and by positioning bolt this cover plate and bowl-shape valve be positioned on the flange in the control mouthful at the upside of bowl-shape valve, have the little inlet that is connected with inlet on the key in the bottom of bowl-shape valve, on the cover board have with the little liquid outlet of the intracavity inter-connection of bowl-shape valve and the pipeline by being provided with little control valve and be connected with liquid outlet on the key.
2, according to claim 1 from compressing switch hydrant, it is characterized in that described liquid outlet is one or more.
