Description

Technical Field

[0001] The invention relates to the technical field of condenser detection, and in particular to a condenser airtightness detection device. Background Art

[0002] Condenser is a common heat exchange equipment, widely used in various industrial processes. Condenser is usually made of metal pipes, such as copper, aluminum, etc., with channels inside for flowing cooling media, such as water, refrigerant, etc. The main function of the condenser is to transfer heat from high-temperature fluids such as steam, flue gas, etc. to low-temperature fluids, causing the high-temperature fluid to undergo phase change, thereby achieving condensation of the substance. During the production process of the condenser, it is necessary to test the sealing performance of the condenser.

[0003] For example, the patent with publication number CN220490326U discloses a dry-type air tightness detection device for automobile condenser pipelines. This patent pressurizes the gas under the action of a gas booster pump, and then discharges the air into the interior of the condenser pipeline through the air outlet pipe, and then detects the sealing of the condenser pipeline under the action of a pressure gauge, which is convenient for staff to operate and improves the accuracy of the detection data. However, in actual use, it is inconvenient to detect the sealing performance of the connection between the condenser pipeline and the air outlet pipe or exhaust pipe, which may be due to leakage caused by improper connection of the joint, which affects the overall detection accuracy of the equipment.

[0016] The present invention provides a condenser airtightness detection device, which has the following beneficial effects:

[0017] 1. Before detecting the airtightness of the condenser, the present invention only needs to pass the two ends of the condenser through the sealing rings and then insert them into the sealing cover, and make them close to the rubber gasket, so that the rubber gasket can be used to seal the sealing plate and the end of the condenser. At the same time, the first rubber ring can seal the sealing ring and the condenser. Therefore, when the piston rod slides inside the piston cylinder, the air inside the piston cylinder can be squeezed into the sealing cover, so that the pressure at one end of the detection cylinder is increased. When the sealing at the interface of the condenser is good, the internal air pressure will push the indicating piston to shrink the reset spring. At this time, the sealing condition of the interface can be observed through the transparent detection cylinder, and when a leak occurs, the reset spring will squeeze the indicating piston to make the indicating piston stay in place. Therefore, the interface can be checked in time to avoid the final detection result being affected by leakage at the interface during subsequent detection, which is beneficial to reduce errors during detection.

[0018] 2. After the condenser is plugged in, the present invention can rotate the internal threaded sleeve to make it slide on the external threaded sleeve, thereby driving the drive ring to move horizontally through the transmission ring and the connecting rod, which can squeeze the end of the drive plate, so that the drive plate rotates at the connection between it and the rotating sleeve, thereby driving the pulley seat to clamp the end of the condenser through the fixed rod and the adjusting sleeve, avoiding shaking between the end of the condenser and the sealing cover during the detection process, resulting in looseness, and in the process of movement of the transmission ring, it can also drive the piston rod to move at the same time, so that the sealing performance of the connection can be detected while clamping, simplifying the steps during operation, saving time and effort.

[0019] 3. In the present invention, since the rubber wheel inside the pulley seat can roll with the outside of the condenser tube, the rotating sleeve can be rotated during detection to fine-tune the position of the pulley seat on the outside of the condenser tube, thereby avoiding air leakage holes at the clamping position that are blocked by the pulley seat and affect the detection accuracy. At the same time, the pulley seat rolls along the outside of the condenser tube, and will not cause the condenser tube to move horizontally, thereby preventing the condenser tube from loosening. The guide strips and guide grooves can limit the rotation direction between the fixed rod and the adjusting sleeve, thereby avoiding the pulley seat from being skewed and reducing the fit with the condenser tube. At the same time, when clamping the ends of condenser tubes of different diameters, the knob can be rotated to rotate the screw rod, thereby changing the extension length of the screw rod from the fixed rod, thereby increasing the clamping range. During adjustment, the adjusting sleeve will also slide on the outside of the fixed rod, so the adjusted position can be conveniently observed through a ruler. After adjustment, the elastic damping pad can also be used to increase the friction between the knob and the adjusting sleeve, which is beneficial to enhancing the stability after adjustment.

[0020] 4. When connecting condensers of different diameters, the present invention selects a sealing ring with a corresponding hole size according to the diameter of the condenser, and when replacing the sealing ring, the stopper can be moved to avoid blocking the rotation of the rotating sleeve, and when the rotating sleeve drives the avoidance opening on the limit ring to align with the card bead, the sealing ring is pulled through the hole in the middle of the sealing ring, and the card bead will slide toward the avoidance opening, thereby facilitating the removal and replacement of the sealing ring, and during installation, after the sealing ring is pressed against the retaining ring, the second rubber ring will improve the sealing performance between the retaining ring and the sealing ring, and then the rotating sleeve is rotated and reset, at this time the limit ring will squeeze the upper part of the card bead to move it along the limit groove, and the card bead will be engaged with the positioning groove, so that the sealing ring can be quickly installed, so that no other tools are needed for replacement, which is very convenient, and after installation, the fixed block and the stopper can be used to limit the rotation angle of the rotating sleeve to avoid the situation where the avoidance opening and the card bead are accidentally aligned due to excessive rotation.

The outer side of the fixed rod 907 is sleeved with an adjusting sleeve 908, and the bottom of the adjusting sleeve 908 is rotatably connected to the pulley seat 909;

[0031] The specific operation is as follows: first, the two ends of the condenser on the workbench 1 are respectively passed through the sealing ring 804 and then inserted into the sealing cover 7, and they are tightly attached to the rubber pad 803, so that the rubber pad 803 can be used to seal the sealing plate 801 and the end of the condenser. At the same time, the first rubber ring 805 will seal the sealing ring 804 and the condenser, and then the internal threaded sleeve 901 is rotated to make it slide on the external threaded sleeve 6, so that the driving ring 904 is driven to move horizontally through the transmission ring 902 and the connecting rod 903, and the end of the driving plate 905 can be squeezed, so that the driving plate 905 rotates at the connection between it and the rotating sleeve 906, so that the pulley seat 909 is driven by the fixing rod 907 and the adjusting sleeve 908 to clamp the end of the condenser, so as to avoid shaking between the end of the condenser and the sealing cover 7 during the detection process, which leads to looseness.

At this time, the sealing condition of the interface can be observed through the transparent detection cylinder 808, and when there is a leak, the reset spring 809 will squeeze the indicating piston 810, so that the indicating piston 810 stays in place. Therefore, the interface can be checked in time. Afterwards, after connecting the two ends of the condenser, the air pump 2 can be started to increase the pressure inside the condenser. At this time, the other end of the condenser is connected to the detection box 3 through the hose 5.The sealing performance of the condenser can be observed through the pressure gauge 4.
