Abstract

Provided is expansion tank design. An expansion tank is composed of a circulation pipe, a discharge pipe, an expansion pipe, an overflow pipe, a signal pipe and a water adding pipe. The type of the overflow pipe is DN40. The type of the expansion pipe is DN25. The type of the circulation pipe is DN20. The type of the discharge pipe is DN32. The type of the signal pipe is DN20. A tank body is in heat insulation and is provided with a cover plate for preventing the tank from icing during winter heating in cold regions. The expansion tank is provided with the circulation pipe connected to the same horizontal pipe of the expansion pipe, so that water in the expansion tank is in a slow flowing state under the action of the pressure difference of the two connection points. The distance between the expansion pipe and the circulation pipe can be 1.5 m-3.0 m.

Description

A kind of design of expansion tank

Technical field:

The present invention relates to a kind of design of water tank, particularly a kind of design of expansion tank.

Background technology:

When being closed system for air-conditioner water system, what cause because of variations in temperature for making the water in system mentions that expansion gives leeway, and the eliminating be conducive in the air of system, expansion tank should be connected in pipe-line system, open axial flow fan level pressure equipment is simple, it is convenient to control, and hydraulic stability is good, initial cost is low, for ensureing the normal work of expansion tank and water system, in forced circulation system, expansion tank should be connected to the suction side of water pump, namely, on water return pipeline, water tank absolute altitude at least should exceed system peak 1 meter.

Summary of the invention:

Object of the present invention is exactly defect in order to overcome prior art and provides a kind of design of expansion tank.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of design of expansion tank, by circulation pipe, drainpipe, expansion tube, overflow pipe, signal pipe and filling pipe composition, the model of overflow pipe is DN40, the model of expansion tube is DN25, the model of circulation pipe is DN20, the model of drainpipe is DN32, the model of signal pipe is DN20, described casing should be incubated and add cover plate, at cold district, when preventing heat supply in winter, water tank freezes, described expansion tank picks out a circulation pipe, circulation pipe is connected on the same level pipeline connecting expansion tube, make the water in expansion tank under the effect of two tie point pressure reduction, be in slowly travelling state, expansion tube and desirable 1.5-3.0 meters of circulation pipe tie point spacing.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the invention process:

In figure, 1, circulation pipe, 2, drainpipe, 3, expansion tube, 4, overflow pipe, 5, signal pipe, 6, filling pipe.

Detailed description of the invention:

Below in conjunction with accompanying drawing, the present invention is further illustrated.

A kind of design of expansion tank, by circulation pipe (1), drainpipe (2), expansion tube (3), overflow pipe (4), signal pipe (5) and filling pipe (6) composition, the model of overflow pipe (4) is DN40, the model of expansion tube (3) is DN25, the model of circulation pipe (1) is DN20, the model of drainpipe (2) is DN32, the model of signal pipe (5) is DN20, described casing should be incubated and add cover plate, at cold district, when preventing heat supply in winter, water tank freezes, described expansion tank picks out a circulation pipe (1), circulation pipe (1) is connected on the same level pipeline connecting expansion tube (3), make the water in expansion tank under the effect of two tie point pressure reduction, be in slowly travelling state, expansion tube (3) and desirable 1.5-3.0 meters of circulation pipe (1) tie point spacing.
