Drawings
FIG. 1 is a schematic view of the overall construction of a hydrant water stop according to the present invention;
FIG. 2 is a schematic view of the principle of operation of the main body portion of the water stop of the hydrant according to the present invention;
the fire hydrant system comprises a main body 1, a ball storage bin 101, a sealing blind plate 102, a sealing ball 103, a traction rope 104, a fire hydrant elbow 2, a flange 201, a fire hydrant main body 3 and a fixing ring 301.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.
As shown in fig. 1-2, the embodiment of the invention provides a fire hydrant water stop, which comprises a main body 1, a fire hydrant elbow 2 and a fire hydrant main body 3, wherein the main body further comprises a ball storage bin 101, a sealing blind plate 102, a sealing ball 103 and a traction rope 104, the ball storage bin 101 is positioned below the main body 1, the sealing blind plate 102 is positioned below the ball storage bin 101, the sealing ball 103 is installed in the ball storage bin 101, the tail end of the sealing ball 103 is connected with the traction rope 104, the fire hydrant elbow 2 is connected with the fire hydrant main body 3 through a flange 201, the fire hydrant main body 3 further comprises a fixing ring 301, the other end of the traction rope 104 is connected with the fixing ring 301, and the fixing ring 301 is installed on the inner wall of the fire hydrant main body 3.
Further, the main body 1 adopts a tapered volute design, and a flexible rubber coating is adopted inside the main body 1.
Further, the sealing ball 103 has a density greater than that of water, and the middle part of the diameter of the main body 1 is slightly larger than that of the two ends.
Further, the connecting caliber of the flange 201 is larger than that of the main body 1, so that flange connection is facilitated.
The working principle of the fire hydrant water stop is as follows: when the fire hydrant main body is broken by external force impact, the traction rope fixed by the rope fixing device 301 can be dragged at the same time, the position of the sealing ball 103 can be dragged from A to B, the sealing ball cannot move forward after reaching the position B due to the adoption of the tapered volute, the sealing ball plays a role in sealing a pipeline, at the moment, if the dragging force is larger, the traction rope 104 can be automatically disconnected with the sealing ball 103, and if the dragging force generated by the external force impact is not particularly large, the traction rope 104 cannot be disconnected. Regardless of whether the pull-cord 101 is disconnected, the pull-cord 104 needs to be replaced after the system is started to prevent the next failed start.
In conclusion, the invention adopts a mechanical structure without adopting electronic equipment, has quick response and good timely sealing effect; simple structure low cost, convenient installation and manufacture and wide application prospect.
It should be noted that various standard components used in the present invention are commercially available, non-standard components are specially customized, and the connection manner adopted in the present invention, such as bolting, welding, etc., is also a very common means in the mechanical field, and the inventor does not need to describe herein any further.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
