Embodiment Construction

[0018] Below in conjunction with accompanying drawing and by embodiment the present invention will be further described:

[0019] As shown in the figure: the flange stop piece is fixed at the outlet of the inner wall pipe, and a nut with an inner diameter capable of being embedded with the flange plane is fixed at the inner wall of the water tank. There is an inner insulating snare 7, which is set on the pipe, which plays the role of both insulation and sealing. There is an outer insulating snare 8 on the outside of the flange, and an internal thread nut for fixing is provided outside the insulating snare to fix the nut embedded in the flange. , so that the outlet of the pipe is well fixed to the inner wall of the water tank.

[0020] The flange stopper and the nut embedded in the flange plane are generally fixed on the inner wall of the water tank by brazing. The inner insulating ring can be made of one material. Generally, the temperature resistance is required to reach 100-...

Abstract

The invention relates to a sealing device, for packing the outlet channel of heat-insulating layer form the internal wall of metal water tank. The outlet channel protrudes out the wall of water bank, while mounted a flange gasket; a nut or fixing loop contacting the surface of flange is mounted on the internal wall of water bank; insulated loops are installed on the two sides of flange gasket; and a nut contacting the flange surface, an inner screw nut fixing the fixing loop or a flange is mounted out the insulated loop which is on the out side of flange. Said invention has no connecter in the channel of water bank, so the heat exchanger in the water bank has enough strength to support the working pressure of heat pump. It has excellent sealing and delayed heating ability without the leak of water bank.

Description

1. Technical field [0001] The invention relates to a sealing device for an inlet and outlet of a water tank, in particular to a sealing structure for a water tank of a heat pump water heater, a solar water tank and other water heaters. 2. Background technology [0002] Pressure-bearing heat pump water heaters and solar water heaters work at high temperatures. In addition to the surface protection of the steel inner wall, anodic protection is generally required for the inner wall. As far as the water tank of the heat pump water heater is concerned, the energy efficiency ratio of working under normal room temperature conditions is Above 3.0, even in the environment of minus 8 degrees Celsius, the energy efficiency ratio is still about 1.5, and the cooling capacity of the evaporator can also be used as the cooling capacity of the air conditioner in summer. Compared with ordinary electric water heaters, the energy saving effect is extremely significant. It can be made into a lar...
