Abstract
The utility model discloses a high building dire-fighting water-supply pressure relief device. The pressure relief device comprises a first water pipe, a second water pipe and a non-return valve, wherein one end of the first water pipe is connected with a fire engine pump; the other end of the second water pipe is connected with a fire hose; and the non-return valve which only allows water to flow from the first water pipe to the second water pipe is positioned between the first and the second water pipes. By adopting the technical scheme of the utility model, water can be stopped at any moment in the water supply process, and water in the fire hose cannot flow back into the fire engine pump; in the next place, repeated attacks can be organized conveniently, because the reversed flow of pressure water is controlled by the non-return valve, water is still in the fire hose and isn't discharged; moreover, the utility model has the advantages of excellent quality and reasonable price and strong practicability.
Description
Technical field
The utility model relates to fire-fighting domain, especially a kind of high building fire-proof water supply pressure relief device.
Background technology
To the traditional method that high building fire fighting supplies water, be that a spiral switch water knockout drum is set on the fire fighting truck water supply line, when fire fighting truck is cut off the water, open the water knockout drum pressure-relief valve earlier, and then slowly cut off the water, can prevent that like this press water backflow from damaging the fire fighting truck pump.But, consider that from actual combat but there is certain problem in this method, at first be because the branchman can not be in the jetting state in the fire extinguishing operation of reality always, in conversion of hydraulic giant position and replacing water band process, must cut off the water at any time; Next is to be unfavorable for organizing one-pass attack after cutting off the water, though prevented the press water backflow after the release of water band, also simultaneously the water in the water band has been bled off, and also will reorganize water supply when one-pass attack.
Summary of the invention
The utility model purpose is: provide a kind of and can cut off the water at any time and water can not be back to the high building fire-proof water supply pressure relief device of fire fighting truck pump.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of high building fire-proof water supply pressure relief device, it comprises first water pipe that an end links to each other with the fire fighting truck pump, second water pipe that the other end links to each other with fire hose, and it further comprises between first and second water pipe and only allows water to flow to the check valve of second water pipe from first water pipe.
On the basis of technique scheme, also comprise following technical scheme:
It further comprises the 3rd water pipe, and wherein the bearing of trend of the 3rd water pipe is vertical mutually with the bearing of trend of first and second water pipe.
The 3rd water pipe comprises unloading and compresses switch.
Check valve is between first water pipe and the 3rd water pipe.
Having adopted technique scheme, at first is can cut off the water at any time during fire fighting truck supplies water, the fire fighting truck pump that can not flow backwards of the water in the fire hose; Next is to be convenient to organize repeatedly attack, utilizes check valve control because press water refluxes, and the water in the water band also exists, and is not bled off; And after having used pressure relief device of the present utility model, also just there is no need to use the switch water knockout drum.In addition, this pressure relief device also has inexpensive, practical advantage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Please refer to Fig. 1, the utility model provides a kind of high building fire-proof water supply pressure relief device, it comprises first water pipe 1 that an end links to each other with fire fighting truck pump (not shown), second water pipe 2 that the other end links to each other with fire hose 4, be positioned between first and second water pipe (1,2) the 3rd water pipe 3 and between first water pipe 1 and the 3rd water pipe 3 and only allow water to flow to the check valve 5 of second water pipe 2 from first water pipe 1.
The bearing of trend of the 3rd water pipe 3 is vertical mutually with the bearing of trend of first and second water pipe (1,2), also comprise unloading and compress switch 30, it is used for the gas of 4 li of fire hoses is released, because cut off the water when not carrying out supplying water, fire hose has air pressure for 4 li, causes between water band and the water band and cannot pull out, and unloads by this and compresses switch 30, can pull out the tie point of two Pan Shui band, thereby regain the water band.
Adopted technique scheme, can cut off the water at any time in the water supply, the water in the fire hose 4 is because of the effect of check valve 5, and the fire fighting truck pump can not flow backwards back; Next is to be convenient to organize repeatedly attack, utilizes check valve 5 controls because press water refluxes, and the water in the fire hose 4 also exists, and is not bled off; And after having used pressure relief device of the present utility model, also just there is no need to use the switch water knockout drum.In addition, this pressure relief device also has inexpensive, practical advantage.
When embodiment of the present utility model is illustrated and describes, conceivable is that those skilled in the art can design different correction examples of the present invention under the situation of spirit that does not break away from claims and scope.
