Abstract
The utility model relates to the technical field of hydrants, in particular to a fire hydrant outside a surge chamber. The fire hydrant comprises a hydrant body, a valve body, an elbow, a valve rod and a valve rod nut, wherein the lower end of the hydrant body is connected with the upper end of the valve body; the lower end of the valve body is connected with the elbow; the hydrant body, the valve body and the inner chamber of the elbow, which are connected together, form a water flow channel; the valve rod nut is fixedly connected onto the inner wall of the hydrant body through an anti-switching sleeve; the upper part of the valve rod is in threaded connection onto the valve rod nut; a steel ball is arranged at the water outlet of the hydrant body; and an adjusting rod is arranged at one end of the hydrant body and controls the flow through an adjusting device mounted at the water outlet, so that the pressure of a water supply pipe can be effectively controlled by changing the pressure at the water outlet, and unnecessary loss due to the fact that fire extinction equipment is damaged as the pressure is overlarge can be avoided.
Description
Technical field
The utility model relates to the fire plug technical field, particularly a kind of pressure regulation outdoor fire hydrant.
Background technology
The outdoor fire hydrant of commonly using is directly to connect flap through valve rod, comes switch hydraulic pressure through valve rod again.The hydrant of this structure, the pressure of water can not reach the force value of the needed water of rescue personnel, can not effectively control hydraulic pressure, can't satisfy rescue personnel's needs.
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 can control the pressure that flow changes delivery port according to regulating, convenient and practical, the pressure regulation 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 pressure regulation outdoor fire hydrant; Comprise key, valve body, elbow, valve rod and valve stem nut; The lower end of described key connects the valve body upper end, the lower end connecting bend of valve body, and the key that links together, valve body and elbow inner chamber constitute a water stream channel; Described valve stem nut is fixed on the key inwall through anti-reducing sleeve, and described valve rod top is screwed onto on the valve stem nut, and the delivery port place of said key is provided with a steel ball, and an end of said key is provided with adjusting rod.
Compared with prior art; The utlity model has following outstanding advantage and effect: the size that the adjusting device of installing through delivery port is regulated flow; Change the required pressure of delivery port the pressure of feed pipe is controlled effectively, can not make fire-extinguishing apparatus damage and cause unnecessary loss because of pressure is excessive.
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 pressure regulation outdoor fire hydrant comprises key 1, valve body 2, elbow 3, valve rod 4 and valve stem nut 5, and the lower end of described key 1 connects valve body 2 upper ends; The lower end connecting bend 3 of valve body 2, the key 1 that links together, valve body 2 and elbow 3 inner chambers constitute a water stream channel; Said valve stem nut 5 is fixed on key 1 inwall through anti-reducing sleeve, and described valve rod 4 tops are screwed onto on the valve stem nut 5, and the delivery port place of said key 1 is provided with a steel ball 6, and an end of said key 1 is provided with adjusting rod 7.
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.
