Abstract
Institutional advancement type fire hydrant is by the valve body, installs valve rod on the valve body, lid and establish and constitute at the valve gap of valve body upper end, the lower extreme of valve body sets up the water inlet, sets up the delivery port on the lateral wall of valve body, and the hand wheel is connected to the upper end of valve rod, and the lower extreme of valve rod is established in the lower extreme inboard of valve body, and the lower extreme of valve rod is provided with the valve clack with the junction of valve body, and the water inlet department at the valve body is closely put to the valve clack, the water inlet department of valve body, the junction of valve body and valve rod is and establish and be provided with the decompression disk seat at the downside position of valve clack promptly, the water inlet runner of valve body sets up to the back taper shape, the utility model discloses a decompression disk seat is installed additional in back taper water inlet department at the valve body to having reduced the use at the decompression orifice plate of the delivery port of valve body lateral wall department, having reduced the use of spare part, reduced the cost of manufacture of product, pressure -relief is showing very much, the imported runner of valve body water inlet department back taper not only makes pressure -relief accord with national standard, has more reduced to surge and the emergence of the phenomenon of vacuole because of the rivers that the orifice plate that reduces pressure formed.
Description
Technical field
The utility model belongs to fire-fighting equipment technical field, and what be specifically related to is a kind of structure-improved fire hydrant.
Background technology
Along with the fast development of national economy, in the high-rise building in city, fire hydrant must be installed, in order to the generation of fire preventing rigidly; Because the hydraulic pressure entered in fire hydrant is general relatively high, particularly its hydraulic pressure of high-rise building is then larger, therefore under the state of water under high pressure, how better utilizing fire hydrant, to make the water not surge that flows out and cavity, is people's urgent problems always; The structure of common fire hydrant adopts the way installing pressure reducing orifice at water outlet additional; And installing the cost of manufacture that pressure reducing orifice adds product on the one hand additional, effect of easing stress is undesirable on the contrary; On the other hand because fire hydrant is placed on outdoor no supervision for a long time, therefore the most easily lose, thus affect the normal use of fire hydrant; In view of this, the present inventor is for this type of technical disadvantages, and restudy the internal structure of fire hydrant, this case is life therefrom.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, and low cost materials reduces, and the significant structure-improved fire hydrant of effect of easing stress.
The utility model is achieved through the following technical solutions: structure-improved fire hydrant, and the valve gap being located at valve body upper end by valve body, the valve rod be arranged on valve body, lid forms; The lower end of this valve body arranges water inlet, the sidewall of valve body sets out the mouth of a river, and the upper end of valve rod connects handwheel, and the lower end of valve rod is located at the lower end inside of valve body, and the junction of the lower end of valve rod and valve body is provided with flap, this flap closely puts the water inlet at valve body; It is characterized in that: the described water inlet at valve body, namely valve body and valve rod junction and the position, downside being located at flap is provided with Pressure relief valve seat; The water inlet passage of valve body is set to reverse tapered shape.
The water outlet that described body wall is arranged is provided with hermaphroditic coupling.
The beneficial effects of the utility model embody and are: compared with prior art, the utility model installs Pressure relief valve seat additional by the back taper water inlet at valve body, thus decrease the use of the pressure reducing orifice of the water outlet at body wall, decrease the use of parts, greatly reduce the cost of manufacture of product, but effect of easing stress highly significant; And the inlet channel of valve inleting water mouth place back taper not only makes effect of easing stress meet national standard, and further reduce the generation of phenomenon of current surge and the cavity formed because of pressure reducing orifice.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is the utility model cross-sectional view.
Following is each concrete title identified in figure: 1, handwheel; 2, valve rod; 3, flap; 4, valve body; 5, Pressure relief valve seat; 6, water inlet; 7, delivery port; 8, hermaphroditic coupling; 9, valve gap.
Detailed description of the invention
As shown in Figure 1, structure-improved fire hydrant, the valve gap 9 being located at valve body 4 upper end by valve body 4, the valve rod 2 be arranged on valve body 4, lid forms; The lower end of this valve body 4 arranges water inlet 6, the sidewall of valve body 4 sets out the mouth of a river 7, and this delivery port 7 place is provided with hermaphroditic coupling 8, and described hermaphroditic coupling 8 external hose carries out water spray and goes out; The upper end of valve rod 2 connects handwheel 1, and the rotation of handwheel 1 both can with the rotation of ovable valve stem 2; The lower end of valve rod 2 is located at the lower end inside of valve body 4, and the junction of the lower end of valve rod 2 and valve body 4 is provided with flap 3, and this flap 3 is closely put in the water inlet of valve body 4, namely utilizes flap 3 to block the water inlet of water inlet 6; At water inlet 6 place of valve body 4, namely valve body 4 and valve rod 2 junction and the position, downside being located at flap 3 is provided with Pressure relief valve seat 5, Pressure relief valve seat 5 is arranged on water inlet 6 place and effect of easing stress can be made obvious; And water inlet 6 runner of valve body 4 is set to reverse tapered shape, can greatly reduce the generation of current surge and cavitation phenomena.
Occupation mode of the present utility model is, rotate handwheel, rotate with ovable valve stem 2 and the flap 3 that is connected with valve rod 2, therefore running water flow in the inner chamber of valve body 4 from the water inlet 6 of valve body 4, water-band is arranged on hermaphroditic coupling 8 place at valve body 4 sidewall upper water-out mouth 7 place, flow into the water of valve body 4 inner chamber and then flow in hermaphroditic coupling 8 to go out from water-band external shunt and use fire extinguishing.
The design of the utility model fire hydrant meets GB3445-2005 " indoor fire hydrant " design standard; To the effect of easing stress highly significant of water under high pressure, and greatly reduce the generation of current surge and cavitation phenomena.
