Description

A kind of pipeline exhausting device that is used for solar water heater

Technical field

The utility model relates to a kind of auxiliary equipment of solar water heater, specifically is meant a kind of pipeline exhausting device that is used for solar water heater.

Technical background

At present, solar water heater has been widely used in the middle of the daily life, to the improvement and the energy savings aspect of resident living condition having played good effect.In northern China also is like this.But, use solar water heater but to be subjected to the restriction of weather temperature in the north of China's cold, as be installed in outdoor for solar water heater water tank up and down the upper and lower conduit of water be easier to freeze because of it contains water, the application of solar water heater is restricted.In order to solve the problem that upper and lower conduit easily freezes, the outer wall at upper and lower conduit that has increases heat-insulation layer and heater is set, though this kind method has solved the problem of freezing, but increased material cost, power consumption is big, and heater also exists potential safety hazard, fire hazardous.Be head it off, the inventor had once applied for " inflatable emptier ", the patent No. is 200420011958.2, this patent utilization siphon principle has solved the problem of enduring cold in the upper and lower conduit road well, but also there is a problem in this patent, because supplying water often appears stopping in shortage of water resources or discontinuity supplies water, and such situation occurs and just can't make solar water heater regular supply hot water.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of prior art, and provides a kind of simple in structure, the upper and lower conduit road that can effectively the remove solar water heater pipeline exhausting device of phenomenon of enduring cold.

For achieving the above object, the technical scheme that is provided is: a kind of pipeline exhausting device that is used for solar water heater, include check valve, tee pipe fitting and motor-driven valve, two ports in 3 ports of wherein said tee pipe fitting, be connected with check valve on one port, one port is connected with motor-driven valve, in tee pipe fitting, be provided with the starting bar of a hinge joint on the tee pipe fitting wall, starting bar one end contacts with the silica gel check plug that check valve contains, and the silica gel stop valve in the starting bar other end and the motor-driven valve contacts.

A top flat with holes is installed in the described check valve, and top flat one side contacts with silica gel check plug, and opposite side contacts with starting bar one end, top flat is set can prevents effectively that starting bar from damaging silica gel check plug.

Described motor-driven valve is made up of valve body, actuator and valve shaft, be with the silica gel stop valve on the valve shaft by actuator control, pass through by the inwall clutch for clutch control water yield that valve shaft drives in silica gel stop valve and the valve chamber, described silica gel stop valve is provided with a projection, the corresponding contact configuration with starting bar one end of this projection.

Owing to adopt such scheme, silica gel check plug, the silica gel stop valve in the motor-driven valve in starting bar that is provided with in the tee pipe fitting and the check valve interact, thereby check valve, tee pipe fitting and motor-driven valve three are effectively combined, form a tube emptying emptier that is used for solar water heater.During application, pipeline exhausting device is installed in the inner end cap of outside water box and the bottom side between the outer end cap, one port of tee pipe fitting and a port of check valve are connected on the upper and lower conduit road, the water inlet in water tank is connected in the upper and lower conduit road that links to each other with check valve, and a port of motor-driven valve and the delivery port of water tank join.When the hot water of water tank through motor-driven valve, tee pipe fitting, the upper and lower conduit road is to the destination, as shower nozzle, after stopping using, start motor-driven valve, valve shaft moves under the effect of actuator, inwall in silica gel stop valve on the valve shaft and the valve chamber closes and closes, pass through by hot water, simultaneously, the silica gel stop valve presses an end of starting bar, passes through lever principle, starting bar other end top (perhaps starts masthead to top flat to the silica gel check plug of check valve, the top flat top is to silica gel check plug), thus the reverse direction of check valve is also communicated, and then whole upper and lower conduit road is communicated with the water tank upper atmosphere, under the situation of normal atmosphere (An), surplus water in the upper and lower conduit road outside the drain, reaches the tube emptying effect under the natural situation of gravity, and then has solved the pipeline phenomenon of enduring cold.The utility model is simple in structure, easy for installation, utilize existing check valve, tee pipe fitting and existing motor-driven valve is made reforming processing slightly, in tee pipe fitting, add starting bar again, promptly can be assembled into a pipeline exhausting device, and effect is very good, has solved the northern problem of utilizing the solar water heater yard piping to occur enduring cold of puzzlement always.
