Description

Technical Field

[0001] The present invention relates to the technical field of public medium service stations, and particularly to a public medium service station with a pressure relief function. Background Art

[0002] In the daily production of the petrochemical industry, public media (such as steam, nitrogen, industrial air, industrial water, etc.) service stations are often used to blow and displace the soft-connected process pipelines, so that the materials in the process pipelines are blown into the designated storage equipment to meet the maintenance conditions of the process pipelines.

[0003] After using the service station, generally, the valve on the process pipeline side is closed first, and then the valve on the service station side is closed. In this way, a certain pressure will accumulate in the soft-connected rubber hose and cannot be released. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that a certain pressure will accumulate in the soft-connected rubber hose in the prior art and cannot be released. By means of a pressure relief facility, the pressure in the soft-connected rubber hose between the service station and the process pipeline is released first, and then the rubber hose is removed, effectively avoiding the safety accident of injury caused by removing under pressure due to the inability to release the pressure in the soft-connected rubber hose. A public medium service station with a pressure relief function is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A public medium service station with a pressure relief function includes a bottom plate. There are multiple bottom plates, and the multiple bottom plates are arranged in parallel. Both sides of the top of the bottom plate are fixedly connected with support plates, and the tops of the two support plates are fixedly connected with the same top plate. Multiple arc-shaped grooves are provided on the top of the top plate and the top of the bottom plate. A process medium pipeline is arranged on the top of the bottom plate, and multiple public medium pipelines are arranged on the top of the top plate. Multiple sealing cover assemblies are arranged on the tops of the top plate and the bottom plate, and the sealing cover assemblies are used to fix the public medium pipelines and the process medium pipelines;

[0007] A discharge pipe is fixedly communicated with the bottom of the public medium pipeline. The bottom of the discharge pipe is fixedly communicated with an outer cylinder. An inlet pipe is fixedly communicated with the top of the process medium pipeline. A quick interface is arranged on the top of the inlet pipe, and a soft-connected rubber hose is arranged inside the quick interface. The soft-connected rubber hose and the outer cylinder are connected by a connecting component;

[0008] A pressure relief device for pressure relief is arranged on one side of the discharge pipe.

[0009] In a possible design, the capping assembly includes a horizontal groove and a vertical groove formed at the top of the bottom plate. The horizontal groove and the vertical groove are vertically arranged and communicate with each other. A slider is slidably connected inside the horizontal groove. A side block is fixedly connected to the top of the slider, and an arc-shaped pressing plate is fixedly connected to the top of the side block.

[0010] In a possible design, a top block is fixedly connected to the top of the arc-shaped pressing plate. The two top blocks cooperate with each other. A positioning groove is formed on one side of the top block, and a positioning rod is fixedly connected to one side of the top block. The positioning rod is used in cooperation with the positioning groove.

[0011] In a possible design, a second rectangular block is slidably connected to the inner wall of the horizontal groove. The same spring is fixedly connected between one end of the second rectangular block and one inner wall of the horizontal groove. A first rectangular block is slidably connected to one inner wall of the vertical groove. The same compression spring is fixedly connected between one side of the first rectangular block and one inner wall of the vertical groove. Both the first rectangular block and the second rectangular block are used in cooperation with the slider.

[0012] In a possible design, the connecting assembly includes a sliding plate slidably connected inside the outer cylinder. A plurality of limiting rods are fixedly connected to the bottom of the sliding plate. A plurality of limiting grooves are formed on the bottom inner wall of the outer cylinder. The limiting grooves are engaged with the limiting rods.

[0013] In a possible design, one end of the flexible connecting rubber hose is fixedly connected with an oval plate. Two symmetrically arranged circular grooves are formed on both sides of the oval plate. A circular rod slidably penetrates through the inside of the circular groove. One end of the two circular rods on the same side is fixedly connected with the same arc-shaped plate. The same tension spring is fixedly connected between one end of the circular rod and one inner wall of the circular groove.

[0014] In a possible design, the arc-shaped plate and the oval plate are used in cooperation with the outer cylinder. Two symmetrically arranged inclined blocks are fixedly connected to the bottom of the sliding plate. The inclined blocks are used in cooperation with the arc-shaped plate.

[0015] In a possible design, a second valve is arranged on one side of the discharge pipe, and a first valve is arranged on one side of the feed pipe.

[0016] In this application, during use, the medium inside is transported through the flexible connecting rubber hose to the inside of the process medium pipeline through the common medium pipeline. First, close the first valve and then close the second valve. Use the pressure relief device to first release the pressure inside the flexible connecting rubber hose between this service station and the process pipeline, and then remove the rubber hose, which can completely and effectively avoid the safety accident of personal injury caused by removing under pressure due to the inability to release the pressure inside the flexible connecting rubber hose.

[0017] When installing the flexible connection rubber hose, the elliptical plate and the arc plate at one end of the flexible connection rubber hose can be inserted into the interior of the outer cylinder together. At this time, the elliptical plate and the arc plate form a circle. When the elliptical plate moves upward, it will push up the sliding plate, and the sliding plate drives a plurality of limit rods to move upward, and the limit rods move out of the interior of the limit slots;

[0018] At this time, the flexible connection rubber hose can be rotated. The flexible connection rubber hose drives the elliptical plate to rotate, and the elliptical plate drives the two arc plates to rotate. At this time, the inclined block is inserted between the elliptical plate and the arc plate, and then the arc plate can be pushed to move horizontally. The two arc plates move away from each other, and then the round rod can move out of the interior of the round slot, and the tension spring is stretched. When the horizontal slot moves into the interior of the outer cylinder, the elliptical plate cannot move out. At the same time, under the impact of the medium, the sliding plate abuts against the elliptical plate, and then the stability of the flexible connection rubber hose can be ensured;

[0019] And when it is necessary to replace the process medium pipeline or the common medium pipeline, the two top blocks can be moved horizontally. The two top blocks drive the two arc pressing plates to move away from each other. The two positioning rods move out of the corresponding positioning slots respectively, and the arc pressing plate can drive the slider to move horizontally in the horizontal slot. The slider pushes the second rectangular block to move horizontally. The second rectangular block compresses the spring. When the second rectangular block moves to one side of the first rectangular block, the arc pressing plate is loosened at this time. The first rectangular block pushes the slider to move longitudinally under the elastic force of the compression spring, and the slider moves from the interior of the horizontal slot to the interior of the vertical slot, and then the two arc pressing plates can be made to move away from each other and move away from the top of the common medium pipeline, which can facilitate the removal of the common medium pipeline and the process medium pipeline and is convenient for replacing the common medium pipeline or the process medium pipeline.

[0020] Beneficial effects:

[0021] In the present invention, for the common medium service station with a pressure relief function, through the connection assembly, the flexible connection rubber hose and the outer cylinder can be quickly connected, and then the flexible connection rubber hose can be conveniently and quickly connected to different common medium pipelines, greatly reducing the workload of workers and improving work efficiency;

[0022] In the present invention, for the common medium service station with a pressure relief function, through the cover assembly, the tops of the common medium pipeline and the process medium pipeline can be covered, and then the stability of the common medium pipeline and the process medium pipeline can be ensured, and when replacing the process medium pipeline and the common medium pipeline, tools are not required, reducing the operation difficulty;

[0023] In the present invention, the efficiency and security of the public medium service station system are improved, and the potential safety hazard problem caused by removing the flexible connection after using the public medium service station is effectively solved. At the same time, the present invention has broad application prospects and market prospects, and plays a promoting role in the technical development of the public medium service station.
