Abstract
The utility model discloses a water releasing device of a fire hydrant, which is arranged at the bottom of a hydrant body; a valve rod is arranged in the hydrant body; a valve flap is arranged at the lower end of the valve rod; a valve base is arranged on a valve body of the hydrant valve; a drain valve plug is arranged on the valve base; two circular annular dummy clubs for sealing are arranged on the valve plug; a screw nut and a small spring are arranged at the lower end of the drain valve plug; a first water outlet is arranged on the valve base, and a second water outlet is arranged on the valve body of the hydrant valve. The water releasing device of a fire hydrant of the utility model has the advantages of simple and reasonable structure, sensitive response, high reliability and obvious water drainage effect.
Description
Technical field
The utility model relates to a kind of water draw-off of fire plug.
Background technology
The water draw-off of fire plug generally is contained in the bottom of key.Behind the fire plug end-of-job, water draw-off is responsible for the surplus water in the key is discharged, and avoids surplus water freezing to destroy key, influences the normal use of fire plug.Traditional water draw-off sluicing speed is slow, unstable properties.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and it is fast to propose a kind of sluicing speed, working stability, sensitive fire plug water draw-off.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of fire plug water draw-off, be installed in the bottom of key, valve rod is contained in the key, flap is equipped with in the valve rod lower end, and valve seat is contained on the bolt valve body, and the draining valve plug is contained on the valve seat, there are two round ring boss to be used for sealing on the valve plug, nut and little spring are equipped with in the lower end of draining valve plug, are provided with first outfall on valve seat, are provided with second outfall on bolt valve body.
Compare with prior art, the utlity model has following beneficial effect: simple and reasonable, be quick on the draw, the reliability height, drainage effect is obvious.
Description of drawings
Fig. 1 is to use the structure chart of the fire plug of the utility model fire plug water draw-off;
Fig. 2 is the partial enlarged drawing of fire plug water draw-off shown in Figure 1.
Wherein, 1 is valve rod; 2 is key; 3 is flap; 4 is valve seat; 5 is bolt valve body; 6 are the draining valve plug; 61 is the cylindrical annular boss, and 62 is interior round ring boss, and 7 is nut; 8 is little spring; A is first outfall; B is second outfall.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figures 1 and 2, fire plug water draw-off of the present utility model is installed in the bottom of key 2, valve rod 1 is contained in the key 2, flap 3 is equipped with in valve rod 1 lower end, and valve seat 4 is contained on the bolt valve body 5, and draining valve plug 6 is contained on the valve seat 4, cylindrical convex annular 61 and interior round ring boss 62 are arranged on the draining valve plug 6, nut 7 and little spring 8 are housed in the lower end of draining valve plug 6, on valve seat 4, are provided with the first outfall a, on bolt valve body 5, be provided with the second outfall b.Be sealed into soft seal between the draining valve plug 6 and the first outfall a.
When fire plug was started working, flap 3 moved downward under the effect of valve rod 1, valve open.Simultaneously, draining valve plug 6 moves downward under the effect of little spring 8 and hydraulic pressure, and cylindrical annular boss 61 and interior round ring boss 62 are pressed on the valve seat 4 simultaneously, seals the first outfall a, makes water mouthful outflow from then on.
When the fire plug end-of-job, flap 3 moves upward under valve rod 1 and hydraulic action, until contacting with valve seat 4, forms sealing, valve closing.Flap 3 is forced upwards jack-up with draining valve plug 6 when moving upward, the first outfall a exposes, and the surplus water in the key 2 is discharged from the first outfall a and the second outfall b.
Therefore, fire plug water draw-off of the present utility model is simple and reasonable, be quick on the draw, and the reliability height, drainage effect is obvious.
Claims (2)
1, a kind of fire plug water draw-off, be installed in the bottom of key, it is characterized in that: valve rod is contained in the key, flap is equipped with in the valve rod lower end, and valve seat is contained on the bolt valve body, and the draining valve plug is contained on the valve seat, there are two round ring boss to be used for sealing on the valve plug, nut and little spring are equipped with in the lower end of draining valve plug, are provided with first outfall on valve seat, are provided with second outfall on bolt valve body.
