The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Such as Fig. 1, it is provided with and changes the utility model proposes a kind of heat exchanger exempted to tear open plate and changed, including closing housing 2, inside it
Hot device 1, the feed pipe 3 and primary water pipe 4 being connected with heat exchanger 1 pass through closing housing 2；Water supply branch pipe 6, it is placed in envelope
Outside closed shell body 2, the both ends of water supply branch pipe 6 are connected with a feed pipe 3 respectively, and bypass pump 8 is provided with water supply branch pipe 6.
Install the outside of heat exchanger 1 in existing heating system additional closing housing 2, the once water supply of original heat exchanger 1
Pipe 3 and primary water pipe 4 are stretched out through closing housing 2.Feed pipe 3 and primary water pipe 4 are through the position of closing housing 2
Carry out encapsulation process.
In addition, closing housing 2 can be made by casting, access hole can be also equipped with housing 2 by closing, and access hole is with being engaged
Capping carry out sealing blocking.It can be used between capping and access hole and install elastic washer realization sealing additional.Close the inner wall of housing 2
Thermal insulation material can also be installed additional.
Water supply butterfly valve 301 and backwater butterfly valve 401, above-mentioned confession are respectively equipped with above-mentioned 3 and first return pipe 4 of a feed pipe
Water branch pipe 6 is placed between water supply butterfly valve 301 and heat exchanger 1.After water supply butterfly valve 301 and backwater butterfly valve 401 are closed, water supply branch pipe
6 form a closed circuit with heat exchanger 1.
An above-mentioned feed pipe 3 is equipped with dosing branch pipe 9, and dosing branch pipe 9 is located between the both ends of above-mentioned water supply branch pipe 6；
Dosing ball valve 901 is installed on dosing branch pipe 9.Such as Fig. 1,9 position of dosing branch pipe contributes to added cleaning agent to exist
The inside of heater 1 is sufficiently entered under the action of bypass pump 8, plate swap-in row is effectively cleaned.
Above-mentioned primary water pipe 4 is equipped with blow down branch 5, and blow down branch 5 is located at above-mentioned backwater butterfly valve 401 and heat exchanger 1
Between；Blow down branch 5 is equipped with Blowoff ball valve 501.
Above-mentioned water supply branch pipe 6 is equipped with two release valve balls 7, and two release valve balls 7 are respectively positioned at the water inlet of bypass pump 8
Side and water outlet side.
Above-mentioned closing housing 2 is equipped with visual windows, and the position of visual windows is corresponding with the nameplate of above-mentioned heat exchanger 1；
The glass lens 201 that visual windows are flush-mounted on closing housing 2 cover.Above-mentioned glass lens 201 are magnifying glass.With with putting
The sealing covering visual windows of glass lens 201 of big function, on the one hand do not destroy the obturation effect of integrally closed housing 2；It is another
Aspect, can also make staff clearly read the information on 1 nameplate of heat exchanger, the specification of such as heat exchanger.
The utility model adds water supply branch pipe 6 on a feed pipe 3 of existing heat exchanger 1, and on water supply branch pipe 6

It should be noted that the utility model is only to install the technical side of water supply branch pipe 6 and bypass pump 8 additional a water side
Illustrated exemplified by case.Since in existing heating system, the water quality of a water side is dirtier compared to secondary water side, also more difficult
Processing.And the water quality of secondary water side is preferable in itself, and generally all water softening device can be added in the side in existing heating system,
Therefore it is weaker to the demand of special cleaning.But the utility model, which does not represent, to install water supply branch pipe 6 and side additional a water side
Logical pump 8, equally, is used in combination operating mode, can also install water supply branch pipe 6 and bypass pump 8 additional at the same time in secondary water side.
Described in the utility model to exempt to tear the heat exchanger that plate changes open, simple in structure, transformation is easy to maintain.By once supplying water
Install water supply branch pipe 6 and bypass pump 8 on pipe 3 additional, can be by bypassing the water of increase of pump 8 when a water side insufficient water
Water supply flow.When needing to clean plate swap-in row, cleaning agent can be added by original sewage draining exit on a feed pipe 3,
And played a role in promoting by bypassing 8 pairs of cleaning agents of pump, help it to change interior carry out wash cycles in 1 plate of heat exchanger.By
The outside of heat exchanger 1 installs closing housing 2 additional, on the one hand can heat exchanging device 1 protected, avoid its corrosion or destroyed；
On the other hand also there is heat insulation function, increase the heat exchange efficiency of heat exchanger 1.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
