Abstract
The utility model discloses a temperature-sensitive water replenishing device of a solar water heater, which belongs to fittings of the solar water heater; the structure of the device includes an upper shell body and a lower shell body, wherein, the upper shell body provided with a water inlet is fixed and arranged on the lower shell body, and the lower part in the lower shell body is provided with a bracket which is provided with a water outlet hole; a valve spool is arranged above the bracket, an inner cavity of the cylinder valve spool is provided with a solid wax, and a thimble is arranged between the valve spool and the bracket; the top of the thimble passes through the bottom of the valve spool and is contacted with the solid wax inside the valve spool, and the bottom end of the thimble is contacted with the bracket; a spring is arranged between the valve spool and the upper shell body. Compared with the prior art, the temperature-sensitive water replenishing device of the solar water heater of the utility model has the characteristics of reasonable design, simple structure, small volume, low cost, reliable performance, easy installation and wide application scope, etc.
Description
Technical field
The utility model relates to a kind of solar water heater accessory, specifically solar water heater temperature sense water replenishing device.
Background technique
At present, in the temperature of solar water heater control water charging system, the temperature sensing device of use mainly contains dual mode, and one is a solenoid valve, this valve work flexibly but poor reliability, working life is short; It is two for having the self-supporting temperature-sensing valve of sense line, and this valve body amass big cost height, and it is limited press holding position, uses and limits to greatly.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, provide a kind of rational in infrastructure, volume is little, cost is low, the solar water heater temperature sense water replenishing device of reliable performance.
The technological scheme that its technical problem that solves the utility model adopts is: this device comprises upper shell and lower shell body, the upper shell that is provided with water intake is fixedly mounted on the lower shell body, bottom in the lower shell body is provided with the support that has osculum, the top of support is provided with spool, be provided with solid wax in the inner chamber of cylindrical spool, be provided with thimble between spool and the support, the bottom that spool is passed on the top of thimble contacts with solid wax in the spool, the bottom of thimble contacts with support, is provided with spring between spool and the upper shell.
The diameter of described spool bottom greater than in the spool, the body diameter on top, the spring bottom is fixed on the spool bottom.
The diameter of described spool bottom is greater than the diameter at lower housing cavity position, support place.
The spool bottom contacts with the sealing of lower housing cavity wall under the effect of spring, when entering water temp reaches the spool setting temperature, swollen the rising that be heated ejects thimble to solid wax in the valve core cavity, thimble reacts on spool, separate with the lower housing cavity wall spool bottom, and lower shell body is flowed out in the space of constant temperature water between spool bottom and lower housing cavity wall, when entering water temp is lower than setting temperature, spool bottom and lower housing cavity wall closure, formation is opened circuit.
Solar water heater temperature sense water replenishing device of the present utility model is compared with prior art, have reasonable in design, simple in structure, volume is little, cost is low, reliable performance, be easy to by characteristics such as dress, wide accommodations.Except that being applied to field of solar energy, also be widely used on the various temperature control liquid switches.
