Abstract
The invention discloses a liquid indicator for a solar water heater. The liquid indicator comprises an upper spherical shell and a lower spherical shell which are hollow. The upper spherical shell is communicated with the lower spherical shell through an indicating pipe, a heat shield is arranged on the outer side of the upper spherical shell, a regulating valve penetrating the heat shield is mounted at the top of the upper spherical shell, and a liquid inlet pipe is arranged at the lower end of the lower spherical shell. Volume of changing of air is quantized, and the changing of air is converted into changing of liquid level; moreover, for heat insulation, the amount of volume change of the air is different due to the fact that density of liquid and height of the liquid level are different; besides, having functions of energy conservation and environment protection and being free of sensors, the liquid indicator is simple and practical, convenient to mount and especially applicable to water level monitoring of the domestic solar water heater.
Description
technical field:
The present invention relates to level monitoring device, relate in particular to a kind of solar water heater liquid level gauge.
background technology:
At present, the common use of people is the liquid level gauge of the boiler water gauge made according to law of connected vessels and the belt sensor made according to the physical principle such as optical, electrical.
For above-mentioned two kinds of liquid level gauges, be of limited application at present and water level is high that time inconvenience is observed.Though the liquid level gauge of belt sensor accurately trouble is installed, cost is high, sensor may bring pollution.Now, people when using solar water heater also in the urgent need to a kind of simple and practical popular liquid level gauge.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of solar water heater liquid level gauge, according to relation between the isothermal process pressure of closed gas under the pressure feature of liquid and certain mass, volume, design, can observe accurately the SEA LEVEL VARIATION of solar water heater.
Technical scheme of the present invention is as follows:
Solar water heater liquid level gauge, it is characterized in that: comprise the upper spherical shell of hollow, lower spherical shell, between upper spherical shell and lower spherical shell, by Shi Guan UNICOM, the outside of upper spherical shell is provided with heat shield, upper spherical shell top is provided with the variable valve through heat shield, and the lower end of described lower spherical shell is provided with feed tube.
Described solar water heater liquid level gauge, is characterized in that: described upper spherical shell, lower spherical shell, show pipe and heat shield all adopt transparent material to make.
Advantage of the present invention is:
1, the present invention quantizes by the volume that gas is changed, and is converted into the variation of liquid level; Moreover, be exactly heat insulation, due to fluid density, liquid level difference, gas volume variable quantity is also different;
2, energy-conserving and environment-protective of the present invention, have saved sensor, simple and practical, easy for installation.Be specially adapted to domestic solar water heater's water level monitoring.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the first regulating step view of the present invention.
Fig. 3 is the second regulating step view of the present invention.
embodiment:
Referring to accompanying drawing:
Solar water heater liquid level gauge, the upper spherical shell 1, the lower spherical shell 2 that comprise hollow, between upper spherical shell 1 and lower spherical shell 2, by Shi Guan 3 UNICOMs, the outside of upper spherical shell 1 is provided with heat shield 4, upper spherical shell 1 top is provided with the variable valve 5 through heat shield 4, and the lower end of lower spherical shell 2 is provided with feed tube 6.
Upper spherical shell 1, lower spherical shell 2, show that pipe 3 and heat shield 4 all adopt transparent material to make, generally select transparent, inelastic plastics or glass to make, show that pipe 2 can be straight, support spherical shell 2.
Step is installed and used in the concrete adjusting of the present invention:
1, according to treating the maximum height of liquid level gauge, corresponding liquid level gauge is installed, the woven hose of joint 7, triangle vavle 8 and testing liquid for liquid level gauge is connected, setting height(from bottom) with apart from ground 1.5 meters be advisable, close triangle vavle 8 and variable valve 5;
2, the container of simply measuring is filled with to liquid, the maximal value that can reach at ordinary times;
3, the first regulating step: open variable valve 1, rotate gently triangle vavle 8, make liquid just arrive spherical shell 1 bottom under liquid level gauge, close triangle vavle 8 and variable valve 5, referring to Fig. 2;
4, the second regulating step: again open triangle vavle, allow liquid flow into liquid level gauge, meter internal pressure increases.When liquid is static, regulate variable valve 5, make to show that in pipe 3, liquid level reaches most significant digit, can't arrive ball, close variable valve 5, installation, referring to Fig. 3.
5, the 3rd regulating step: later variable valve 5 forever cuts out, and triangle vavle 8 is often opened after this shows maximum (little) value corresponding the maximum of tested liquid level (little) value just of managing liquid level when liquid is static.
The present invention designs according to relation between the isothermal process pressure of closed gas under the pressure feature of liquid and certain mass, volume.The acting in conjunction of hydraulic pressure and air pressure, has determined the volume of gas; The variation of liquid level causes the variation of hydraulic pressure, thereby causes the variation of sealing gas volume.As long as the present invention is switched on the woven hose of testing liquid, just can monitor the variation of liquid level.
For solar water heater, can be designed to easy series of products, because the bucket footpath of sun power bucket is almost identical, just highly different, indoor temperature change generated in case neither be very large.
