Abstract
The utility model discloses an emptying device for a water pipe of a solar water heater mainly for the drainage of solar upper and lower water pipelines for preventing the water pipe from freezing in severe cold winter. The emptying device for a water pipe of a solar water heater is composed of an n-shaped water pipe (2) arranged in a water storage tank (1) and an air pressing barrel (3) communicated at the lower ends of the upper and lower water pipelines (10). Water is charged into the air pressing barrel (3) through a water inlet (6). Water in the upper and lower water pipelines (10) is pressed by air pressure in the barrel and is discharged into the water storage tank (1). Thereby, an effect that the water in the upper and lower water pipelines is drained can be achieved.
Description
A kind of solar water heater water pipe emptier is mainly used in the draining in the outdoor upper and lower conduit of solar water heater road.
As everyone knows, solar water heater is by installing at outdoor heat collector, water storage box, the upper and lower conduit road is formed, when solar water heater is in user mode, always be full of water in the upper and lower conduit road, so cause the loss of part heat, two the winter of severe cold its outdoor section water pipe often caused solar water heater to use by bursting by freezing, still do not have effective solution so far.
The objective of the invention is to overcome the shortcoming of prior art, providing a kind of can have in the solar water heater water storage box under the state of water, and the device of ponding in the emptying upper and lower conduit road effectively prevents in severe cold outdoor upper and lower conduit in winter road by the problem of bursting by freezing.
The present invention realizes with following technical scheme: this emptier by the ∩ shape water pipe in the water storage box and be communicated with the upper and lower conduit road calm the anger the bucket form, one end of ∩ shape water pipe is connected the water inlet of water storage box and is communicated with in the upper and lower conduit road, exhaust outlet at the bucket of calming the anger is equipped with venting check valve, calm the anger the bucket the lower end water inlet and discharge outlet are arranged, the top of ∩ shape water pipe must be higher than the backwater waterline of water tank.When needing the water in the emptying upper and lower conduit road, open the water intaking valve of barrel bottom of calming the anger, water enters in the bucket, pressure by running water, upward motion of air in the compressing bucket is opened venting check valve, and the water in the air push upper and lower conduit road enters in the water storage box, treats to close inlet valve after water has all been arranged, be vacuum state this moment in the upper and lower conduit road: because of the top of ∩ shape pipe exceeds the water surface, water can't fall after rise.Reach the effect of water pipe anti-freezing in winter.
Below in conjunction with accompanying drawing the present invention is described in further detail:
Accompanying drawing 1 is a structural representation of the present invention
With reference to accompanying drawing 1, ∩ shape water pipe (2) is installed in the interior one of water storage box (1) and is terminated at the water inlet of water storage box and connects in upper and lower conduit road (10), the bucket (3) of calming the anger is communicated with upper and lower conduit (10) by water pipe, in its exhaust ports venting check valve (4) is housed, intake valve (5) is arranged at staving top, the staving below is provided with water inlet (6), draining valve (8).During by dress, calm the anger bucket (3) device indoor, when the water in the need emptying upper and lower conduit road (10), close other valve, open valve (7), water fills in the entrance pressure gas bucket (3), the hydraulic pressure that air in the bucket is charged into is forced to motion, valve (4) is opened, and the water of air compressing pipeline upwards flows in the water storage box (1), and valve-off (7) gets final product after the water in the pipeline (10) is all discharged.Draining valve (8) is used to bleed off the water in the bucket, and intake valve (5) air inlet usefulness during water in longer (3) is in closed condition at ordinary times.During hot water, open valve (9) in need use water storage boxes (1), the water in the water pipe flows out, and forms negative pressure in the water pipe (10), and the water in the water storage box just falls from eminence from the interior sucking-off of pipe.
Claims (3)
1, a kind of solar water heater water pipe emptier, feature of the present invention is made up of the bucket (3) of calming the anger that installs the ∩ shape water pipe (2) in water storage box (1) and be communicated with upper and lower conduit road (10), one end of ∩ shape water pipe (2) is connected on the water inlet of water tank and in upper and lower conduit (10) and is communicated with, exhaust outlet at the bucket (3) of calming the anger is equipped with venting check valve (4), and there are water inlet (6), discharge outlet (8) in the lower end.
2, solar water pipe emptier according to claim 1 is characterized in that the top of the ∩ shape water pipe (2) of device in water storage box (1) must be higher than the backwater waterline of water tank.
3, solar water heater water pipe emptier according to claim 1 is characterized in that on the bucket (3) of calming the anger intake valve (5) being arranged.
