Description

Technical Field

[0001] The utility model relates to the technical field of sealing test devices, and specifically to a water filling port sealing test device. Background Art

[0002] Coolers are a type of heat exchange equipment used to cool fluids and are widely used in metallurgy, chemical industry, energy, transportation, light industry, food and other industrial fields. Before leaving the factory, all coolers must be tested for tightness. Some coolers or supporting expansion water tanks have water inlets, which also need to be tested for tightness.

[0003] At present, the commonly used method for testing the sealing of the water filling port is to use the corresponding pressure cap for sealing test. Under low pressure conditions, the sealing performance of the pipe on the water filling port may not be detected, and after being used several times, the sealing performance of the pressure cap deteriorates, that is, it cannot be used and can only be scrapped, with high losses. Under high pressure conditions, using a pressure cap that can withstand high pressure will most likely cause deformation and scratches of the water filling port, causing customer complaints. Utility Model Content

[0006] Furthermore, in the above-mentioned water inlet sealing test device, there is an inwardly protruding fastening structure below the lock, and the fastening structure matches the boss of the water inlet, so as to facilitate the installation of the lock and the water inlet and improve the stability of the connection.

[0007] Furthermore, in the above-mentioned water filling port sealing test device, the pressure plate and the rubber layer are circular structures, and the diameter is consistent with the inner diameter of the lock.

[0008] Furthermore, in the above-mentioned water inlet sealing test device, the lower part of the frame is a circular structure with openings at both ends, and the diameter of the upper opening is smaller than the lower opening. A support frame is provided above the frame, and a connecting through hole is provided in the middle of the upper part of the support frame.

[0009] Furthermore, in the above-mentioned water filling port sealing test device, the pressure plate is a double-layered circular plate, the upper layer is a connecting plate, and the lower layer is a lower pressure plate.

[0010] Furthermore, in the above-mentioned water inlet sealing test device, a connecting port is provided on the connecting plate, and the size of the connecting plate is consistent with the size of the opening above the frame.

[0012] Furthermore, in the above-mentioned water inlet sealing test device, the inner side of the connecting through hole is provided with a thread that cooperates with the screw rod. The screw rod is slowly pressed down by rotating the handle to control the downward pressure.

[0013] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the water filling port sealing test device described in the utility model has a simple structure, and the lock buckle is buckled under the water filling port boss. The pressure plate is pressed down by twisting the screw rod with a handle, and the rubber layer under the pressure plate seals the end face of the water filling port, which can reduce the loss of the pressure cover used in common tests and avoid damage to the water filling port, thereby reducing the test cost, and is easy to operate and has good practicality.
