Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As shown in Figures 1 to 4: a kind of from letting out antifreeze fire hose reel, including the outdoor rain-proof casing 1 being positioned on support 25, reel assembly 2 it is provided with in outdoor rain-proof casing 1, reel assembly 2 has been coiled long high-pressure hose 3, and the end of this long high-pressure hose 3 is provided with flexible pipe hydraulic giant 4, here flexible pipe hydraulic giant 4 can be straight stream nozzle, it can also be water fog nozzle, the other end of above-mentioned long high-pressure hose 3 connects with short high-pressure hose 5, and the bottom of described short high-pressure hose 5 manually ball valve 7 is connected with pipeline 9, pipeline 9 is disposed with Pressure gauge 8, fire valve 6 and flange bending 10, the bottom surface of described flange bending 10 is additionally provided with Manual draining valve 24, in outdoor rain-proof casing 1, it is additionally provided with fire-fighting lance 26 and fire hose 27 simultaneously；
nullThe end of above-mentioned flange bending 10 is connected with from the valve head 11 letting out frost valve group，Valve head 11 is connected with key 18 by extension pipe 14，It is additionally provided with defecator 22 in the water inlet of key 18 bottom，Cam switch 12 it is rotatably connected in valve head 11，The lower section of cam switch 12 is provided with depression bar 13，And the top of this depression bar 13 contacts with the bottom surface of cam switch 12，The lower end of depression bar 13 is provided with connecting rod 15，The bottom of connecting rod 15 is connected with valve rod 17 by contiguous block 28，The bottom of valve rod 17 is provided with second voltage regulation mechanism 21，Valve rod 17 is gone back movable sleeve and is connected to one-level pressure regulating device 20，And on one-level pressure regulating device 20, offer perforate，Pressure spring 16 also it is socketed with on valve rod 17 between contiguous block 28 and one-level pressure regulating device 20，And one-level pressure regulating device 20 matches with the valve seat 19 being positioned at key 18，Described contiguous block 28 is additionally provided with automatic draining mechanism 23，This automatic draining mechanism 23 matches with Auto-drainage valve seat 29，And Auto-drainage valve seat 29 is connected with the discharge pipe line being opened in key 18 side.
Certainly the work process letting out antifreeze fire hose reel of this utility model embodiment is as follows: the important area in petrochemical enterprise arranges this utility model embodiment.When there is the condition of a fire, a people is first turned on the chamber door of outdoor rain-proof casing 1, stretches long high-pressure hose 3, holds flexible pipe hydraulic giant 4(direct current/water fog nozzle) and open switch, another people switchs 12 with special spanner opening cam, can implement injection.
If need greater flow uses water, can be closed by manual ball valve 7, stretch fire hose 27, then access fire valve 6 after being connected with fire hose 27 by fire-fighting lance 26, another people uses special spanner opening cam
Switch 12, can implement injection.
nullAfter opening cam switch 12，Depression bar 13 drivening rod 15、Valve rod 17 moves down，First second voltage regulation mechanism 21 separates with the one-level pressure regulating device 20 on valve rod 17，First press water flows out between one-level pressure regulating device 20 and second voltage regulation mechanism 21，To reduce the press water longitudinal pressure to one-level pressure regulating device 20，When cam switch 12 continues rotation and depression bar 13 and valve rod 17 etc. continue to move down，One-level pressure regulating device 20 will separate with valve seat 19，Now，If there being water pressure fluctuations，By the way of controlling the anglec of rotation of cam switch 12，Guarantee effect pressure on each face of one-level pressure regulating device 20 and second voltage regulation mechanism 21 and pressure spring 16 realize autobalance each other，Make outlet pressure in safety value，To ensure that the spray reaction forces of hydraulic giant is unlikely to slip out of the hand period，Thus ensure that the operation safety of fire fighter.
Opening and implementing in fire-fighting fire extinguishing or cooling procedure, the automatic draining mechanism 23 linked by contiguous block 28 with valve rod 17 is pressed on Auto-drainage valve seat 29 all the time, discharge pipe line is closed, after fire-fighting fire extinguishing or cooling terminate, cam switch 12 resets, under the effect of pressure spring 16, linkage depression bar 13, connecting rod 15, move on valve rod 17, one-level pressure regulating device 20 and valve seat 19, second voltage regulation mechanism 21 is in close contact with one-level pressure regulating device 20, automatic draining mechanism 23 also with on move, automatic draining mechanism 23 disengages with Auto-drainage valve seat 29, the water body remained in key 18 is discharged by discharge pipe line；Simultaneously after opening manual drain valve 24, the remaining water of fire hose reel intracavity is discharged the most rapidly, thus prevent in the winter time because of remaining water because of freezing, volume become the generation of havoc integrally-built situation.
