Abstract
The utility model relates to the technical field of hydrants, in particular to a rotating outdoor hydrant. The rotating outdoor hydrant comprises a hydrant body, a rotating head, a bent head, a valve rod and a valve rod nut, wherein the upper end of the hydrant body is connected with the valve rod through the valve rod nut and provided with an anti-transfer sleeve on the valve rod nut, the lower end of the hydrant body is connected with the rotating head, the lower end of the rotating head is inlaid into the bent head, the rotating head and the hydrant body are hermetically connected through steel balls and an O-shaped sealing ring, and a cavity of together connected hydrant body, rotating head and bent head forms a water flow passage. According to the utility model, the valve body is replaced with the rotating head to be sealed, and the rotating outdoor hydrant can freely rotate at an angle of 360 degrees so that the direction of a water outlet is changed, and therefore, the pressure of the water outlet of a water supply pipe is effectively ensured and unnecessary loss of fire-fighting equipment can not be caused due to insufficient water pressure.
Description
Technical field
The utility model relates to the outdoor fire hydrant technical field, particularly a kind of rotation outdoor fire hydrant.
Background technology
Outdoor fire hydrant commonly used all is to be fixedly connected on the fire protection pipeline, and the delivery port direction is fixed extremely, can not rotate freely.The hydrant of this structure; Therefore the fire hose or the fire fighting truck water band that connect in the delivery port direction can bend; Sudden and violent broken or flow reduces the force value that can not reach the needed water of rescue personnel because of bending causes to make the water band under the hydraulic pressure pressure in pipeline; Can not effectively control hydraulic pressure, can't satisfy rescue personnel's needs, bring very big obstacle to fire-fighting and rescue.
The utility model content
In order to overcome the above-mentioned weak point that exists in the prior art, the purpose of the utility model is to provide a kind of and can rotates freely by 360 degree, and the delivery port direction freely changes as required, and is convenient and practical, the rotation outdoor fire hydrant of being convenient to make.
In order to reach above-mentioned purpose; The utility model adopts following concrete technical scheme: a kind of rotation outdoor fire hydrant; Comprise key, swivel head, elbow, valve rod and valve stem nut, said key upper end is connected with valve rod through valve stem nut, and on valve stem nut, is provided with anti-reducing sleeve; The lower end of said key connects swivel head, and the lower end of swivel head is bumped in the elbow, is tightly connected through steel ball and O RunddichtringO between said swivel head and the key, and the key that links together, swivel head and elbow inner chamber constitute a water stream channel.
Compared with prior art; The utlity model has following outstanding advantage and effect: through being provided with annular steel ball between swivel head and the key; Replace valve body to seal swivel head, can rotate freely by 360 degree, thereby change the delivery port direction; The delivery port pressure of feed pipe is effectively guaranteed, can make fire-extinguishing apparatus cause unnecessary loss inadequately because of hydraulic pressure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing the utility model is done further to specify.
The specific embodiment
As shown in Figure 1, a kind of rotation outdoor fire hydrant comprises key 1, swivel head 2, elbow 3, valve rod 4 and valve stem nut 5, and said key 1 upper end is connected with valve rod 4 through valve stem nut 5, and on valve stem nut 5, is provided with anti-reducing sleeve 6; The lower end of said key 1 connects swivel head 2, and the lower end of swivel head 2 is bumped in the elbow 3, is tightly connected through steel ball 8 and O RunddichtringO 9 between said swivel head 2 and the key 1; The key 1 that links together, swivel head 2 and elbow 2 inner chambers constitute a water stream channel; Replace valve body to seal swivel head, can rotate freely by 360 degree, thereby change the delivery port direction; The delivery port pressure of feed pipe is effectively guaranteed, can make fire-extinguishing apparatus cause unnecessary loss inadequately because of hydraulic pressure.
What should explain at last is: above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
