Abstract
The utility model relates to a quickly-opened hydrant with small flow resistance, which is composed of a connecting buckle, a bent pipe, an O type sealing ring, an upper valve body, a lower valve body, a spherical body, a valve rod, a handgrip, etc. The quickly-opened hydrant with small flow resistance has the features of small flow resistance and quick opening, and is an ideal hydrant for fire-fighting and fire-extinguishing.
Description
The utility model is that a kind of flow resistance is little, opens fast fire hydrant, belongs to fire-fighting equipment.
At present, the fire hydrant of application roughly is divided into two kinds, and a kind of is stop valve formula fire hydrant, and this fire hydrant opening speed is slow, opens handwheel and rotates a circle, and only opens several millimeters height, and this fire hydrant is extremely disadvantageous for fire-fighting fire extinguishing.Occurred the fire hydrant that a kind of butterfly valve type is opened recently again, though this fire hydrant has overcome the slow shortcoming of opening speed, after opening, the butterfly plate of butterfly valve influences flow rate of liquid in passage, form certain flow resistance.This also is disadvantageous for fire-fighting fire extinguishing.
It is fast that the purpose of this utility model provides a kind of opening speed, and flow resistance equals generally not have the fire hydrant of the flow resistance of other obstacle pipeline, makes when fire extinguishing, open fast, flow resistance is little.
The utility model is realized with following technological scheme: at first adopt the open-shut device of ball valve as fire hydrant, as the open-shut device of fire hydrant, promptly can opening speed fast, the passage place be without hindrance again with ball valve, and its flow resistance only is equivalent to the pipeline flow resistance.By down valve body, upper valve body, valve seat, spheroid, handle, gland nut, O RunddichtringO, limited ring, bend pipe, connect buckle, middle flange seal circle forms.Earlier valve seat is packed into up and down in the valve body, again spheroid is packed into up and down in the valve body, spheroid and valve seat are formed sealing and are paid, valve rod is connected with spheroid, and valve rod is connected with handle, and the upper valve body outlet is connected with bend pipe, limited ring is equipped with in bend pipe and upper valve body outlet joint, by seal ring sealing, to fix by gland nut, the bend pipe head connects with connecing to link.Upper and lower valve body joint is sealed by mother and sons' seal ring.
It is fast to the utlity model has opening speed, and the characteristics that the liquid flow resistance is little are desirable fire hydrants of fire-fighting fire extinguishing.
Now in conjunction with the accompanying drawings the utility model is further described.
Fig. 1 is that the utility model master looks sectional view.
Fig. 2 is the plan view of the utility model mothers and sons O RunddichtringO.
Fig. 3 is the plan view of the utility model mothers and sons O RunddichtringO.
Fig. 1~3rd, the utility model specific embodiment.Valve seat 2 is packed into to descend in valve body 1 and the upper valve body 11, and in the valve body 1, spheroid 4 linked with valve rod 3 under spheroid 4 was packed into, and handle 5 is connected with valve rod 3, is fixed by nut, and mothers and sons O RunddichtringO is placed in the upper and lower valve body adpting flange seal groove.Mothers and sons O RunddichtringO is the whole mothers and sons O of the composition type circle that small one and large one O type circle combines.Rather than separate, fastening by fastening piece then, seal ring 7 seal groove of packing into, upper valve body 11 links with bend pipe 9, and bend pipe 9 outsides are processed with restraining groove, and limited ring 8 is packed into behind the restraining groove, and is with gland nut 6 fastening.Earlier gland nut 6 is screwed into bend pipe 9 external screw-thread places, limited ring 8 is inserted in along bend pipe 9 outsides again, limited ring 8 is steel garden rings, has one section gap on the ring of garden, has elasticity, and certain stretchability is arranged.Limited ring 8 is inserted in along bend pipe 9 outsides shifts onto in the restraining groove, in the seal groove of again seal ring 7 being packed into, then, the outlet and the bend pipe 9 of the ball valve upper valve body 11 that installs aligned.With gland nut 6 backspins, tighten with the outside thread connection of upper valve body 11 outlets.Bend pipe 9 is connected with 11 outlets of ball valve upper valve body.Bend pipe 9 with connect button and 10 be connected, the port water receiving source capsule road, bottom of following valve body 1, the connecing of bend pipe detained 10 and is connected with the water hose of fire nozzle.When using, when moving among the figure handle 5 to position, water is just from nozzle ejection fire extinguishing.The utility model is compared with at present general fire hydrant, has and opens soon the characteristics that flow resistance is little.Comparing with the butterfly valve type fire hydrant, have the little characteristics of flow resistance, is the desirable fire hydrant of fire-fighting fire extinguishing.
Claims (2)
1, a kind of flow resistance is little, open fast fire hydrant, bend pipe 9 with connect button and 10 be connected, it is characterized in that the outside, bend pipe 9 bottoms processes at restraining groove, limited ring 8 is positioned at restraining groove, bend pipe 9 is connected with 11 outlets of ball valve upper valve body, valve seat 2 is positioned at upper valve body 11 and following valve body 1, and spheroid 4 is arranged in upper valve body 11 and following valve body 1, and spheroid 4 links with valve rod 3, handle 5 links with valve rod 3, and mother and sons' 0 type circle 12 is positioned at upper and lower valve body joint flange sealing trough.
2, a kind of flow resistance according to claim 1 is little, opens fast fire hydrant, and the flange seal circle is the whole mothers and sons O type circle that small one and large one O type circle combines and forms in it is characterized in that.
