Description

Technical Field

[0001] The utility model belongs to the technical field of automatic overpressure discharge nozzle manifold, and in particular relates to a safety protection device for an automatic overpressure discharge nozzle manifold. Background Art

[0002] The automatic overpressure blowdown manifold is an advanced fluid handling equipment that combines automation technology with the functions of the blowdown manifold. It can automatically perform blowdown operations when the fluid pressure exceeds the preset threshold to ensure the safety and stability of the system. The automatic overpressure blowdown manifold is mainly composed of pressure sensors, control valves, blowdown pipelines and related connectors. The pressure sensor is responsible for real-time monitoring of fluid pressure changes. Once the pressure reaches or exceeds the preset safety threshold, the sensor will immediately send a signal to the control system. After receiving the signal, the control system will quickly open the control valve to allow the fluid to be blown through the blowdown pipeline, thereby reducing the pressure in the system.

[0003] Although the current automatic overpressure blowdown manifold has an overpressure protection function, it lacks the function of automatically detecting leaks at the connection and needs to rely on manual inspections to detect leaks. Due to insufficient leak detection, once a leak occurs at the manifold connection, it may cause a safety accident and pose a threat to the staff and the surrounding environment. Moreover, only through manual inspections, it is impossible to detect leaks in time when a leak occurs. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0028] An automatic overpressure blowdown pipe manifold safety protection device comprises a base 1 installed below the blowdown pipe manifold connection, a threaded rod 2 is penetrated through the top of the base 1, a lifting sleeve 3 is sleeved on the top of the threaded rod 2, a turning handle 4 is penetrated through the left side of the base 1, and the turning handle 4 is rotatably connected to the base 1, a rotating rod 5 is rotatably connected to the bottom of the inner wall of the base 1, and a first bevel gear 6 is fixed to the top of the rotating rod 5, a second bevel gear 7 is fixed to the right end of the turning handle 4, a mounting box 8 is bolted to the top of the lifting sleeve 3, and the mounting box 8 is located below the flange of the blowdown pipe manifold connection, and a liquid sensor 9 is installed at the bottom of the inner wall of the mounting box 8.

[0029] The second bevel gear 7 is meshed with the first bevel gear 6, and the diameter of the second bevel gear 7 is larger than that of the first bevel gear 6. The bottom end of the threaded rod 2 passes through the interior of the base 1 and is fixedly connected to the top of the first bevel gear 6. The threaded rod 2 is threadedly connected to the inner wall of the lifting sleeve 3. When the handle 4 rotates, the second bevel gear 7 drives the first bevel gear 6 to rotate, and then the first bevel gear 6 quickly drives the upper threaded rod 2 to rotate, so that the upper lifting sleeve 3 moves.

[0030] Guide blocks 11 are fixed below the left and right sides of the lifting sleeve 3, and guide rods 12 are fixed on the left and right sides of the top of the base 1. The guide rods 12 penetrate the guide blocks 11 and are slidably connected to the inner walls of the guide blocks 11. After the threaded rod 2 rotates, the guide blocks 11 on both sides guide the lifting sleeve 3, so that the lifting sleeve 3 can only move up and down, thereby adjusting the height of the installation box 8 above.

[0031] Guide plates 10 are fixed on both sides of the top of the installation box 8, and the guide plates 10 are tilted as a whole. Through the setting of the guide plates 10, the collection range of the installation box 8 can be expanded. When leakage occurs at the connection, the leaked liquid can be collected and guided so that the liquid sensor 9 below can monitor it.

[0032] Box bodies 13 are installed on both sides of the left and right inner walls of the installation box 8, and the interior of the box bodies 13 is filled with desiccant. A plurality of through holes 14 are provided on the surfaces of the opposite sides of the box bodies 13. When the device is installed in a humid environment for use, in order to avoid condensation of water droplets on the surface of the inner wall of the installation box 8, the desiccant in the box bodies 13 can effectively absorb the surrounding moisture to avoid false triggering of the liquid sensor 9.

[0033] A rain shield 15 is provided above the installation box 8, and the area of ​​the rain shield 15 is larger than the area of ​​the installation box 8. Connecting rods are fixed on both sides of the bottom of the rain shield 15, and the connecting rods are bolted to the surface of the installation box 8. When it rains, the rain shield 15 above can effectively shield the installation box 8 to prevent rainwater from flowing into the interior of the installation box 8 and contacting the liquid sensor 9.

[0034] Working principle: When the automatic overpressure relief nozzle manifold is connected to the pipeline, the staff can take out the device and move the base 1 to the bottom of the flange at the connection. Then the staff shakes the handle 4 on one side, so that the first bevel gear 6 drives the upper threaded rod 2 to rotate, so that the lifting sleeve 3 pushes the installation box 8 to move upward. According to the height of the connection, the installation box 8 is brought close to the connection. After the adjustment is completed, the liquid sensor 9 can monitor the connection. When there is a leak at the connection, the leaked liquid will directly enter the installation box 8 below. After the leaked liquid contacts the liquid sensor 9, the liquid sensor 9 will sound an alarm, and the staff can rush to deal with the leak in time.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
