Abstract

The utility model discloses a floating roof damage prevention device. The floating roof damage prevention device comprises a pressure reducer, a pressure relief pipe, a first bracket and a second bracket, wherein the first bracket and the second bracket are respectively arranged at two end parts of the pressure relief pipe, and the pressure reducer is arranged on the pressure relief pipe. In the floating roof damage prevention device disclosed by the utility model, when sweeping gas passes through the pressure reducer and generates pressure loss, after gas pressure at the outlet of the pressure reducer is reduced, the sweeping gas is gradually released through the pressure relief pipe, thus, impact of the sweeping gas is reduced, and damage to the floating roof caused by pipeline sweeping is prevented.

Description

Anti-floating roof damage device

Technical field

The utility model relates to anti-tamper means, particularly relates to a kind of anti-floating roof damage device.

Background technology

Each refinery, chemical plant and oil depot during residual liquid, are often used the gas purging pipeline (title pipeline purging) that has pressure in removing storage tank inflow pipeline.But internal floating roof tank, when blowing pipeline, because gaseous tension is excessive, easily damages the inner floating roof of storage tank after in other enter tank.Damage the inner floating roof of storage tank when preventing blowing pipeline, therefore designed floating roof damage device.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of anti-floating roof damage device that reduces purge gas pressure.

Utility model content

Anti-floating roof damage device of the present utility model, comprises pressure reducer, relief tube, the first bracket and the second bracket, and described the first bracket and the second bracket are located at respectively the both ends of relief tube, and described pressure reducer is located on relief tube.

Further, described the first bracket and the second bracket can also be welded in respectively the bottom of relief tube.

Further, described the first bracket and the second bracket adopt corrosion-resistant steel to make.

Compared with prior art the beneficial effects of the utility model are: anti-floating roof damage device of the present utility model, when purge gas produces loss of pressure through pressure reducer, reduces after pressure reducer exit gas pressure, then through relief tube, purge gas is progressively discharged.Reduce purge gas impulsive force, prevent that blowing pipeline from damaging floating roof.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is birds-eye view of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As depicted in figs. 1 and 2, a kind of anti-floating roof damage device of the present utility model, comprise pressure reducer 1, relief tube 2 and the first bracket 3 and the second bracket 4 that adopt corrosion-resistant steel to make, the first bracket 3 is welded in the left part of relief tube 2, the second bracket 4 is welded in the right part of release 2 pipes, pressure reducer 1 is arranged at the middle part of relief tube 2, and the pressure reducer 1 in the present embodiment can adopt reducing valve, and pressure reducer 1 is for reducing the pressure of purge gas.

Anti-floating roof damage device of the present utility model, when purge gas produces loss of pressure through pressure reducer 1, reduce after pressure reducer 1 exit gas pressure, then through relief tube 2, purge gas is progressively discharged, reduce purge gas impulsive force, prevent that blowing pipeline from damaging floating roof.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
