Description
Technical field
The utility model relates to the device of a kind of solar water heater water emptying.
Background technology
At present, exhaust-valve on the solar water heater is mounted on the outer upper and lower conduit road of water butt, be subjected to Temperature Influence, under the general situation that temperature is lower in the winter time, exhaust-valve is frozen in easily, lost water in the emptying upper and lower conduit effect, to such an extent as to cause whole pipe to be frozen in, cause solar water heater can not normally use in the winter time.
Summary of the invention
The purpose of this utility model is in order to solve the defective of above-mentioned solar water heater emptier, to provide a kind of and can guarantee solar water heater in the winter time, and be not frozen in, can playing the solar water heater emptier of emptying again.
The technical scheme that the invention for solving the technical problem adopted is: solar water heater water exhaust-valve is made up of backguy, protective cap, flexible sealing rubber cover, upper hose end cover, last tube connector, following tube connector, water inlet pipe and water outlet pipe, interior connection, Inlet and outlet water pipe collar, water emptying duckbilled, sealing rubber ring, spring, upper hose end cover, inlet pipe connection, screw rod and nut etc.Backguy, screw rod and inlet pipe connection are linked in sequence together; the inlet pipe connection lower end is equipped with spring; interior connection and water emptying duckbilled are fixed spring; sealing rubber ring is fixed in the groove of water emptying duckbilled; the upper end of flexible sealing rubber cover is fixed on the upper end of inlet pipe connection by nut; the protected cap in lower end of flexible sealing rubber cover is pressed on the upper hose end and puts; interior connection will be gone up tube connector and following tube connector links together, and the Inlet and outlet water pipe collar will descend tube connector and water inlet pipe and water outlet pipe to link together.Two emptying air admission holes are arranged on the described inlet pipe connection, and described going up on the tube connector has two emptying air admission holes, and two paddle holes are arranged on the described Inlet and outlet water pipe collar, and described solar water heater emptying valve is mounted in the inside of solar water heater water-storage bucket.
The beneficial effects of the utility model are: simple in structure, easy to use, can not be frozen in when using in the winter time, and reached the purpose of water in the emptying inlet and outlet pipe lines.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1,1. backguy, 2. protective cap, 3. nut; 4. flexible rubber seal rubber sleeve, 5. upper hose end cover, 6. emptying air admission hole, 7. emptying air admission hole; 8. go up tube connector, 9. interior the connection, 10. descend tube connector, 11. Inlet and outlet water pipe collars; 12. paddle hole, 13. sealing rubber rings, 14. water inlet pipe and water outlet pipes, 15. water emptying duckbilleds; 16. paddle hole, 17. springs, 18. inlet pipe connections; 19. the emptying air admission hole, 20. emptying air admission holes, 21. screw rods.
The specific embodiment
On solar water heater needs during water, open the water intaking valve on the water inlet pipe and water outlet pipe 14, mention backguy 1, drive inlet pipe connection 18, water emptying duckbilled 15 by screw rod 21, water emptying duckbilled 15 is thrown off with Inlet and outlet water pipe collar 11 to be contacted, no longer hermetic seal effect of sealing rubber ring 13, water just flow in the solar water heater water-storage bucket along paddle hole on the Inlet and outlet water pipe collar 11 12 and paddle hole 16 by the gap after throwing off.After the water in the solar water heater water-storage bucket is filled it up with, close the water intaking valve on the water inlet pipe and water outlet pipe 14, unclamp backguy 1, inlet pipe connection 18, water emptying duckbilled 15 restores to the original state under the elastic force effect of spring 17, sealing rubber ring 13 closely contacts with Inlet and outlet water pipe collar 11 and blocks into water, air in the solar water heater water-storage bucket is by emptying air admission hole 7, emptying air admission hole 19, emptying air admission hole 6, emptying air admission hole 20 enters in the inlet pipe connection 18, by the through hole on the water emptying duckbilled 15 hydraulic pressure in the water inlet pipe and water outlet pipe 14 is gone out again, and by discharging valve discharge on the water inlet pipe and water outlet pipe 14, water in the water inlet pipe and water outlet pipe 14 is drained, can not be frozen in the winter lower in temperature again, guarantees that solar water heater also can normally use in winter.
