Description

TECHNICAL FIELD

[0001] The utility model relates to a fire-fighting technical field, concretely relates to a novel pressure device for fire fighting. BACKGROUND

[0002] The pressure device is a container device capable of storing fluid such as oil or air, and the fluid stored in the pressure device is discharged outward through the pipeline provided on the pressure device, so that the fluid is flowed outward to convert the pressure of the fluid into other force and apply the force to an external device, for example, the fluid pressure in the pressure device is output to a steering mechanism, so that the steering mechanism can be rotated with smaller force, and when the pressure device is used in the field of fire fighting, the force required to open the fire-fighting device can be greatly reduced, so that the fire-fighting device can be opened more quickly, and the fire can be extinguished more timely when the fire starts.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still some defects: the existing pressure device controls the outflow of the fluid in the pressure device through the valve on the pipeline, and the fluid pressure in the pressure device is high, so that the flow rate is fast when the fluid is discharged, and therefore, at the moment when the valve is closed, the high-speed fluid will impact the transmission pipeline of the pressure device instantaneously due to the inertia effect, and the transmission pipeline is easily damaged due to repeated impact, and the service life is short, and the pressure device needs to be frequently maintained. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at the defects and deficiencies of the prior art, and provides a novel pressure device for fire fighting with long service life and not easy to be damaged.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel pressure device for fire fighting, comprising a pressure tank filled with high-pressure fluid in an inner cavity and a top cover sealingly arranged on the top of the pressure tank, a plurality of downward pressure cylinders are arranged on the top cover, a downward push plate penetrating the top cover at the top end and connected with the downward pressure cylinders is slidingly and sealingly arranged in the inner wall of the pressure tank, a pressure pipe is arranged at the bottom end of the pressure tank, an opening and closing valve is arranged in the middle segment of the pressure pipe, an anti-impact pipe is arranged on the side of the middle segment of the pressure pipe close to the pressure tank, the anti-impact pipe comprises an upward impact pipe arranged in the middle segment of the pressure pipe and an upward push frame slidingly and sealingly arranged on the inner wall of the upward impact pipe, at the moment when the opening and closing valve is closed, the high-pressure fluid is filled into the upward impact pipe by inertia and pushes the upward push frame to offset the impact force of the fluid by sliding friction.

[0006] Further improvement: the side wall of the pressure tank is further provided with a lifting support.

[0007] Further improvement: the anti-impact pipe further comprises an outward expansion table arranged at the top end of the upward impact pipe, and the outward expansion table is detachably provided with a bursting disc.

[0008] Further improvement is that the inner wall of the up-pushing pipe is provided with a plurality of friction layers.

[0009] Further improvement is that the friction layer is provided with a plurality of friction convex points.

[0010] Further improvement is that the up-pushing frame comprises a sliding ring which is closed and slidingly connected with the inner wall of the up-pushing pipe, and a thrust plate arranged on the inner wall of the sliding ring.

[0011] Further improvement is that the middle section of the thrust plate is integrally formed with an upward convex disc.

[0012] Further improvement is that the outer wall of the sliding ring is provided with a friction ring.

[0013] After the above technical scheme is adopted, the utility model has the beneficial effects that when the pressure device is closed through the on-off valve, the high-impact fluid generated by inertia can be rushed into the up-pushing pipe, thereby pushing the up-pushing frame in the up-pushing pipe to move, so that the impact is offset by the friction between the up-pushing frame and the inner wall of the up-pushing pipe, and when the impact force is too large, the impact pressure can be released in time through the blasting of the bursting disc, thereby avoiding that the impact force is directly applied to the pressure pipe to cause damage to the pressure pipe, so that the service life of the pressure pipe is longer and the pressure pipe is less likely to be damaged.
