Embodiment Construction

[0008] The cold and hot water heat preservation isolation plunger of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] As shown in the figure, the cold and hot water insulation plunger of the present invention includes a plunger metal baffle 1, a foam heat preservation plunger 2, and a seal 4. It is characterized in that the plunger metal baffle 1 is divided into two parts. The sheet type is respectively bonded to the two ends of the foam insulation plunger 2 and is not connected to each other. A seal groove is provided on the cylindrical surface of the plunger metal baffle plate 1 at both ends, and a seal 4 is arranged in each groove. A ferromagnetic material 3 surrounding and bonded to the cylinder surface of the plunger is provided on the cylinder surface of the foam insulation plunger 2 between the metal baffles 1 for interacting with the magnetic position switch outside the stain...

Abstract

The invention relates to a hot-and-cold water heat-preserving isolated plunger piston, which comprises plunger-piston metal baffle plates, a foamed heat-preserving plunger piston and sealing parts, and is characterized in that the plunger-piston metal baffle plates are divided into two pieces which are respectively bonded with but disconnected with both end surfaces of the foamed heat-preserving plunger piston, two sealing-part slots are respectively arranged on the cylindrical surfaces of the plunger-piston metal baffle plates at both ends, the sealing part is arranged in each slot, and a ferromagnetic material which surrounds and is bonded onto the cylindrical surface of the plunger piston is arranged on the cylindrical surface of the foamed heat-preserving plunger piston between the two plunger-piston metal baffle plates and is used for interacting with a switch at a magnetic position outside a stainless-steel water tank.

Description

technical field [0001] The invention relates to an isolation plunger for a water heater that isolates cold and hot water, in particular to an isolation plunger for cold and hot water insulation. Background technique [0002] At present, the traditional cold and hot water isolation plunger is wrapped with a metal material shell on the insulation material, so that the temperature of the hot end is transmitted to the cold end through the metal material shell, resulting in heat loss. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cold and hot water insulation isolation plunger with low energy consumption. [0004] In order to solve the above-mentioned technical problems, the cold and hot water insulation isolation plunger of the present invention includes a plunger metal baffle, a foam insulation plunger, and a seal. It is characterized in that the plunger metal baffle is divided into two pieces and The two ends ...
