Description

Technical Field

[0001] The present invention relates to the technical field of pressure relief devices, and in particular to a portable gas drainer pressure relief device and a method of using the same. Background Art

[0002] The by-product gas in metallurgical enterprises is transported to various users through gas pipelines for recycling. Due to the long pipelines, condensed water will be generated in the pipelines. Usually, a multi-chamber drainer is used to continuously discharge the condensed water to prevent it from accumulating in the pipelines, causing increased load-bearing capacity or freezing and expansion.

[0003] The pressure in the gas pipeline is usually around 10kpa. The multi-chamber drainer is divided into 3-chamber and 4-chamber types by internal partitions. Under normal conditions, the breakdown pressure is ≥30kpa. If the internal partition is corroded and penetrated, the breakdown pressure will be greatly reduced, resulting in gas leakage. When the multi-chamber drainer is in operation, the corrosion condition of the internal partition cannot be judged, and offline pressure testing must be carried out every year according to relevant specifications, which greatly increases the maintenance cost.

[0004] A portable gas drainer pressure testing device capable of performing a rapid and accurate pressure testing on the drainer and a method for using the device are now proposed. Summary of the invention

[0007] The pressure mechanism is installed on the drainer and is used to provide pressure to the drainer, including a micro compressor, a three-way pipe, a cylinder, and a connector. The micro compressor is detachably installed on the device body, the cylinder is fixedly installed on the device body, the cylinder is connected with the micro compressor through the three-way pipe, the output end of the three-way pipe is fixedly connected with the cylinder, the input end of the three-way pipe is fixedly connected with the output end of the micro compressor, the connector is sleeved on the cylinder and limitedly slides with the cylinder, and the connector passes through the device body, and also includes:

[0008] The driving assembly is installed on the drainer and is used to drive the connecting head to perform horizontal rotational movement.

[0009] On the basis of the above technical solution, the present invention also provides the following optional technical solution:

[0015] Further technical solution: the cover plate is detachably mounted on the device body via a first bolt assembly.

[0016] Further technical solution: the micro compressor can be detachably mounted on the device body by snap-fitting.

[0017] The method for using the portable gas drain pressure relief device comprises the following steps:

[0018] S1. Use the linear moving part to pull the bearing box to perform linear movement in the horizontal direction, and the bearing box drives the linear moving part to perform synchronous linear movement, so that the air inlet end of the drainer is sleeved on the connecting head;

[0019] S2, the motor drives the first flat gear to rotate in the horizontal direction, and the first flat gear drives the second flat gear meshing with it to drive the connector to rotate in the horizontal direction. Since the connector and the cylinder are slidably matched and the connector and the device body are threadedly connected, the connector can perform linear movement in the horizontal direction while rotating in the horizontal direction, so that the connector is further inserted into the drainer.

If either the pressure information or the displacement information is not within the corresponding threshold, it indicates that the sealing effect between the connector and the air inlet end of the drainer is poor. At this time, the motor is started to cause the connector to perform a linear spiral motion in the horizontal direction, so that the pressure information and the displacement information are within the corresponding pressure threshold and the displacement threshold;

[0022] S5. Under the condition that the displacement information and pressure information are within the corresponding pressure threshold and displacement threshold, the displacement information and pressure information are dimensionlessly processed and then imported into the sealing evaluation model. The sealing evaluation model outputs the sealing condition coefficient, and the obtained sealing condition coefficient is compared with the preset sealing threshold. If the sealing condition coefficient is outside the sealing threshold, the motor is started to cause the connector to perform linear spiral motion in the horizontal direction, and the pressure information and displacement information are adjusted until the sealing condition coefficient is within the sealing threshold.

[0048] In the embodiment of the present invention, the linear moving member 501 is used to pull the carrying box 502 to perform linear movement in the horizontal direction, and the carrying box 502 drives the linear moving member 501 to perform synchronous linear movement, so that the air inlet end of the drainer 1 is sleeved on the connecting head 304, and the motor 3051 drives the first flat gear 3052 to perform horizontal rotational movement, and the first flat gear 3052 drives the second flat gear 3053 meshing therewith to drive the connecting head 304 to perform horizontal rotational movement. Since the connecting head 304 and the cylinder 303 are slidably matched and the connecting head 304 is threadedly connected to the device body 2, the connecting head 304 can perform horizontal rotational movement while performing horizontal linear movement, so that the connecting head 304 is inserted into the drainer 1 to complete the construction of the air supply channel. At this time, the micro compressor 301 is turned on, and the micro compressor 301 pressurizes and inflates the drainers 1 at different locations, and uses a pressure gauge to detect the air pressure to complete the pressurized breakdown experiment of the drainer.

[0049] The method for using the portable gas drain pressure relief device comprises the following steps:

[0050] S1, using the linear moving member 501 to pull the bearing box 502 to perform linear motion in the horizontal direction, the bearing box 502 drives the linear moving member 501 to perform synchronous linear motion, so that the air inlet end of the drainer 1 is sleeved on the connector 304;

Since the connector 304 and the cylinder 303 are slidably matched and the connector 304 is threadedly connected to the device body 2, the connector 304 can perform linear movement in the horizontal direction while performing the rotational movement in the horizontal direction, so that the connector 304 is further inserted into the drainer 1. At this time, the sealing ring 308 contacts the near end of the drainer 1, and the construction of the air supply channel is completed;

[0052] S3, turning on the micro compressor 301, the micro compressor 301 pressurizes and inflates the drainers 1 at different locations, and uses a pressure gauge to detect the air pressure, thereby completing the pressurized breakdown test of the drainers;

If any of the pressure information and displacement information is not within the corresponding threshold, it means that the sealing effect between the connector 304 and the air inlet end of the drainer 1 is poor. At this time, the motor 3051 is started to cause the connector 304 to perform a linear spiral motion in the horizontal direction, so that the pressure information and displacement information are within the corresponding pressure threshold and displacement threshold;

[0054] S5. Under the condition that the displacement information and the pressure information are within the corresponding pressure threshold and the displacement threshold, the displacement information and the pressure information are dimensionlessly processed and then introduced into the sealing evaluation model. The sealing evaluation model outputs the sealing condition coefficient, and the obtained sealing condition coefficient is compared with the preset sealing threshold. If the sealing condition coefficient is outside the sealing threshold, the motor 3051 is started to start the motor 3051, so as to cause the connector 304 to perform a linear spiral motion in the horizontal direction, and the pressure information and the displacement information are adjusted until the sealing condition coefficient is within the sealing threshold.
