Abstract
The utility model relates to a self emptying device of the water inlet pipe and the water outlet pipe of a solar water heater, which is characterized in that the cylinder of the water heater is provided with a spout hole and a connecting pipe; one end of the connecting pipe is provided with a water discharge valve in the cylinder, the valve body pipe of the water discharge valve is provided with a water inlet, and a valve core is connected with an electromagnet out of the cylinder; the other end of the connecting pipe is connected with water inlet and outlet valves out of the cylinder; one end of an exhaust pipe is positioned above a water containing space in the cylinder, and the other end of the exhaust pipe is communicated with the connecting pipe.
Description
Technical field
The utility model is the defroster that is used for the solar water heater water inlet pipe and water outlet pipe.
Background technology
Prior solar water heater drops to when subzero water inlet pipe and water outlet pipe at warm refrigerant latitudes temperature and freezes easily and result in blockage, and its solution is at the water pipe import and export heat insulation and heating equipment to be installed, and uses this device to have the shortcoming that power consumption is big, increase use cost.
Summary of the invention
The purpose of this utility model is: provide a kind of solar water heater water inlet pipe and water outlet pipe from emptier, it can make solar water heater not freeze to stop up in the cold district use, and simple in structure, and cost is low.
The technical solution of the utility model is: a kind of solar water heater water inlet pipe and water outlet pipe is from emptier, comprise spout hole, the inside and outside connecting leg of connection cylindrical shell on water heater cylindrical shell, the cylindrical shell, it is characterized in that: in cylindrical shell, connecting leg one end is equipped with discharging valve, the water inlet of discharging valve is communicated with the water space capacity of cylindrical shell, the spool of the discharging valve electromagnet outer with being located at cylindrical shell is connected, blast pipe one port places the spout hole top in the cylindrical shell, the other end is communicated with connecting leg, outside cylindrical shell, be equipped with into and out of water valve on the connecting leg.
The course of work of this device is: when putting hot water, electromagnet gets the electric electromagnetic actuation that makes and drives the spool action, and discharging valve is opened, and at this moment the water space capacity in the cylindrical shell is communicated with outward with cylindrical shell, and the hot water in the cylindrical shell flows out by connecting leg.Electromagnet separates when electromagnet cuts off the power supply, and makes the spool return, and discharging valve cuts out, and hot water is disconnected.At this moment the connecting leg below the discharging valve is because an end is communicated with external atmosphere pressure by blast pipe, and the other end is communicated with the outlet valve of often opening, so remain in the hot water emptying automatically in the connecting leg.The effect of blast pipe is: discharging valve cuts out in the connecting leg of back and does not form vacuum state.Supply is opened the water intaking valve on the connecting leg during cold water in water heater, closes outlet valve simultaneously, and running water enters in the cylindrical shell by connecting leg and the blast pipe that is communicated with connecting leg, and cylindrical shell can limit water level and ventilating air by spout hole.Close water intaking valve when stopping to supply water, open outlet valve simultaneously, remain in the cold water emptying automatically in the connecting leg.
The utility model has the advantages that: because water not in the solar water heater water inlet pipe and water outlet pipe so do not freeze blocking problem, uses present technique to substitute original heat insulation and heating equipment, but power saving, reduce use cost, simple in structure again easy to operate.
Description of drawings
Accompanying drawing is the structural representation of the utility model solar water heater water inlet pipe and water outlet pipe from emptier.
Fig. 1 outlet valve, 2 water intaking valves, 3 connecting legs, 4 spools, 5 discharging valves, 6 water inlets, 7 spout holes, 8 cylindrical shells, 9 valve body tube, 10 connecting rods, 11 pull bars, 12 electromagnet, 13 blast pipes, 14 water space capacities.
