Water-testing seal plug and water testing method thereof

Abstract

The invention discloses a water-testing seal plug and a water testing method, and the water-testing seal plug comprises a housing, a cam, a handle, an expansion mechanism, a front retaining ring and a seal ring, wherein the cam comprises two cam contact surfaces which are connected by a plurality of arcs and located at the different distances from the rotating axle center of the cam, and a rotating shaft of the cam is connected with the handle and the expansion mechanism; and the expansion mechanism comprises an expansion body and an expansion block, a groove is formed on the outer surface ofa ladder of the expansion block and a tension spring is placed in the groove and used for clamping and binding the expansion block on the expansion body. When in use, the water-testing seal plug is aligned with an electric heating port, the handle is adjusted to the horizontal position, the expansion body moves upwards, the expansion block becomes large uniformly on the inner side of the tension spring, then the electric heating mounting port is further tightened, and the seal ring simultaneously enters into a concave groove of an electric heating flange plate for compression and sealing so as to achieve the water testing purpose. The water-testing seal plug is simple in structure and convenient to operate, as long as the cam is pressed into the appropriate position by an employee, the expansion block can expand so as to achieve the effect of fixing with the electric heating port, the water-testing seal plug is applicable to line production and the production efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a water test sealing plug and a water test method thereof, in particular to a water test sealing plug of a solar electric heating port and a water test method thereof. Background technique [0002] The auxiliary energy of solar water heater is electric heating, because its electronic components cannot directly contact water, so the electric heating electronic components must be installed after testing the water during the processing. Before installing the electric heating electronic components on the solar tank, conduct a water test and leak detection. The main method currently adopted is to install the sealing ring, the fixing piece and then tighten it with bolts. After the water test is completed, the bolts, fixing pieces, The sealing ring is removed, and then the electric heating electronic components are installed. This method greatly affects the production efficiency and is not suitable for flow operation. [0003] Summary of t...

Problems solved by technology

Water test and leak detection are carried out before installing electric heating electronic components in the solar energy liner. At present, the main method is to install the sealing ring and the fixing piece and then fasten them with bolts. After the water test and leak detection, the bolts, fixing pieces, The sealing ring is disassembled, and then the electric heating electronic components are installed. This method greatly affects the production efficiency and is not suitable for assembly line operation.
