Description

A kind of solar water heater emptier

Technical field

The utility model relates to a kind of water pipe emptier of solar water heater, belongs to technical field of solar water heaters.

Background technology

In the prior art, a kind of solar water heater is arranged, its water inlet pipe and outlet pipe are a pipe, open water supply valve during last water, can go up water, close water supply valve behind the full water; Open during water and use water valve, because there is a segment distance at the water place from the storage tank of solar water heater, and the water in the upper hose does not participate in the water circulation in the solar water heater, so the water that the water initial stage releases is cold water, the existence of this defective is made troubles to the user.

The utility model content

The purpose of this utility model provides a kind of solar water heater emptier, makes after the water water in can the emptying outlet pipe.

The purpose of this utility model is achieved in that a kind of solar water heater emptier, comprise storage tank, magnetic valve, check valve, inductor, use water valve, outlet pipe, the upper end of outlet pipe is divided into two-way, one the tunnel connects storage tank through magnetic valve, another Lu Jingyi check valve is connected atmosphere, described inductor comprises that housing, float and control magnetic valve work the inductive switch that closes, housing is connected the lower end of outlet pipe, float and housing match to merge and are arranged in the housing, inductive switch is arranged on the housing, and lower housing portion is connected by water pipe and used water valve.

When the utility model uses, inductive switch can change on off state with the change in location of float, when float floats in inductor, inductive switch disconnects, closed electromagnetic valve, and can open slightly and use water valve this moment, check valve is opened the connection ambient atmosphere automatically, water in the outlet pipe can be emitted, and, closes and uses water valve during near inductor up to water level; When using, the water level in the standard-sized sheet water valve, inductor descends next time, float falls, the inductive switch action, magnetic valve is opened, and the water in the magnetic valve flows out in a large number, force closed check valve on the one hand, the upper surface of descending on the other hand water impact float can not float float, and inductive switch keeps closed condition, descending current move downward from the gap location between float and the housing, again from discharging with water valve.The utility model can come hot water once opening with water valve, and is easy to use, simple in structure, reliable, can be applicable on the solar water heater.

As further improvement of the utility model, described inductor also comprises an extension spring, and the extension spring upper end is fixed on the inductor housing, and the extension spring lower end is fixed on the float.This technical scheme can play good stable and guide effect to float, simultaneously, can also reduce the elasticity requirement of float.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein, 1 permeability cell, 2 valve seats, 3 spools, 4 magnetic valves, 5 outlet pipes, 6 floats, 7 housings, 8 permanent magnets, 9 use water valve, 10 inductive switches, 11 extension springs, 12 storage tanks.

The specific embodiment

As figure, the solar water heater emptier is mainly by storage tank 12, magnetic valve 4, check valve, inductor, with water valve 9, outlet pipe 5 compositions such as grade, the upper end of outlet pipe 5 is divided into two-way, one the tunnel through magnetic valve 4 connection storage tanks 12, ambient atmosphere is connected through check valve and permeability cell 1 in another road, described inductor is by housing 7, float 6, extension spring 11 and control magnetic valve work inductive switch 10 compositions such as grade that close, housing 7 is connected the lower end of outlet pipe 5, float 6 matches to merge with housing 7 and is arranged in the housing 7, inductive switch 10 is arranged on the housing 7, housing 7 bottoms are connected with water valve 9 by water pipe, extension spring 11 upper ends are fixed on the inductor housing 7, and extension spring 11 lower ends are fixed on the float 6.Check valve is made of spool 3 and valve seat 2, and spool 3 is provided with air-vent, and spool 3 moves upward, and valve seat 2 is pushed down spool 3 and closed air-vent simultaneously, and check valve is in cut-off state, and when spool 3 moved downward, air-vent was opened, and check valve is in opening.Inductive switch 10 is a magnetic switch, float 6 is provided with permanent magnet 8, during water, open with water valve 9, float 6 moves downward, when float 6 moves downward a certain position, inductive switch 10 closures under the effect of permanent magnet 8, the coil on the magnetic valve 4, inductive switch 10, form the closed-loop path between the power supply, get the valve core movement that electric coil drives magnetic valve 4, open magnetic valve 4, the water in the storage tank 12 flows out, and forces check valve spool 3 to rise, close air-vent, check valve ends, the water in the storage tank 12 downwards in outlet pipe 5 enters inductor housing 7, the upper surface of descending water impact float 6, float 6 can not be floated, inductive switch 10 keeps closed condition, and descending current move downward from the gap location between float 6 and the housing 7, again from discharging with water valve 9; After water finishes, close with water valve 9, the residual water in the outlet pipe 5 floats float 6, inductive switch 10 outages, at this moment, can open slightly with water valve 9, check valve is opened under suction function automatically, by bleed off the water in the outlet pipe 5 with water valve 9, and keep float 6 to be in the come-up position, and inductive switch 10 keeps outage, and next time is when using, open with water valve 9, can directly emit hot water.

The utility model is not limited to the foregoing description, and permeability cell 1 can not have yet, and directly connects atmosphere by check valve; Described inductive switch 10 also can be a light-operated switch, and when float 6 moved to a certain position, it was logical to cover light, the inductive switch closure, on the contrary then inductive switch is opened.
