Description
Technical field
The utility model relates to solar water heater field, relates to a kind of solar water heater upper and lower conduit emptier specifically.
Background technology
At present, solar water heater, owing to having significant energy-conserving and environment-protective feature, obtains increasing use, but in use, in upper and lower pipeline, have water, and these water become cold water owing to not circulating, must first bleed off this part cold water before each water, cause waste.And in the winter time, the ponding up and down in pipe easily freezes, and affects the use of solar water heater.The emptier of pipe up and down of present employing needs a large amount of electronic valves and mechanical valve, and also will lay many water pipes in addition, cost is high, uses inconvenience.
Utility model content
The technical problems to be solved in the utility model overcomes above-mentioned defect, provides a kind of solar water heater upper and lower conduit emptier utilizing high-pressure gas emptying upper and lower conduit.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of solar water heater upper and lower conduit emptier, comprise upper and lower conduit, it is characterized in that: described upper and lower conduit comprises interior pipe, outer tube, described interior pipe is squeezable flexible pipe, described outer tube is low elasticity pipe, be provided with the expandable expansion gear of some inflations between described interior pipe, outer tube, described expansion gear is provided with intake valve, air outlet valve, and described intake valve is connected with gases at high pressure feeder.
Improve as one: described interior pipe is rubber hose or fabric flexible pipe.
Improve as one: described outer tube is steel pipe or plastic tube.
Improve as one; Described expansion gear is tightly connected by interior pipe, outer tube to form seal chamber or the soft bag of rubber seal.
Improve as one: described gases at high pressure feeder is air pump or compressed air storage tank.
Owing to have employed technique scheme, the utility model utilizes and passes into gases at high pressure to expansion gear, and pipe in extruding, structure is simple, does not change solar water heater structure, without the need to additional components.And draining is thorough, effective using water wisely.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1 and Figure 2, a kind of solar water heater upper and lower conduit emptier, comprise upper and lower conduit 6, described upper and lower conduit 6 comprises interior pipe 1, outer tube 2, and described interior pipe 1 is rubber hose, and described outer tube 2 is steel pipe, outer tube 2 is as the supervisor of upper and lower conduit 6, outer tube about 2 two ends are connected with solar water container 7 and bathroom delivery port 8 respectively, and be tightly connected as the rubber tube terminal of interior pipe 1 and outer tube 2, between described interior pipe 1, outer tube 2, space is seal chamber.
Described outer tube 2 is provided with intake valve 4, air outlet valve 5, and described intake valve 4 is connected with air pump.
Embodiment 2:
As shown in Figure 1 and Figure 2, a kind of solar water heater upper and lower conduit emptier, comprise upper and lower conduit 6, described upper and lower conduit 6 comprises interior pipe 1, outer tube 2, and described interior pipe 1 is fabric flexible pipe, and described outer tube 2 is plastic tube, interior pipe 1 is as the supervisor of upper and lower conduit 6, interior pipe about 1 two ends are connected with solar water container 7 and bathroom delivery port 8 respectively, and be tightly connected as the plastic tube two ends of outer tube 2 and interior pipe 1, between described interior pipe 1, outer tube 2, space is seal chamber.
Described outer tube 2 is provided with intake valve 4, air outlet valve 5, and described intake valve 4 is connected with compressed air storage tank.
Embodiment 3:
As shown in Figure 1, Figure 3, a kind of solar water heater upper and lower conduit emptier, comprise upper and lower conduit 6, described upper and lower conduit 6 comprises interior pipe 1, outer tube 2, described interior pipe 1 is fabric flexible pipe, and described outer tube 2 is plastic tube, is provided with the soft bag of some rubber seals between described interior pipe 1, outer tube 2, the soft bag of described rubber seal is provided with intake valve 4, air outlet valve 5, and described intake valve 4 is connected with compressed air storage tank.The soft bag of multiple rubber seal can link together, and common use one group of intake valve 4, air outlet valve 5, also can be used alone one group of intake valve 4, air outlet valve 5 by the soft bag of each rubber seal.
Open intake valve 4, compressed air enters expansion gear 3, and in extruding, pipe 1 is out of shape, and the water in interior pipe 1 is squeezed back solar water heater water tank, realizes the object of upper and lower conduit 6 draining.When using hot water, open air outlet valve 5, discharged by expansion gear 3 inner high voltage gas, the hot water in water tank flows down, and directly can use hot water.
