Description

The overflow air-breather of the water yield on a kind of adjustable solar water heater's storage tank

Technical field

The utility model relates to the non-bearing water tank of a kind of solar water heater of being used for and can measure the overflow air-breather of regulation and control to water on it (adding water).

Background technology

At present, the used overflow passage of the non-bearing water tank of commercially available solar water heater is fixed.Have plenty of directly and open a hole, or on the hole, connect a pipe that communicates with atmosphere again on storage tank matrix top; Have plenty of in storage tank matrix bottom and open a hole, in the hole, insert a pipe that communicates with atmosphere again.Therefore, after this storage tank is carried out, just can not send different water level signal by the overflow passage again, thereby can carry out necessary regulation and control to the water yield on it so as to the utilization mechanical system.Like this, because solar water heater's summer or fine day are so incensed that heat is big, the temperature of water just may be very high; And winter or cloudy weather, because it is little to get heat, the temperature of water just may be very low; When be lower than industry standard promptly 45 ℃ more for a long time, just not too be suitable for doing having used of bathing.

The utility model content

The purpose of this utility model is exactly in order to overcome the above-mentioned deficiency of prior art, a kind of overflow air-breather that can regulate and control the water yield on the non-bearing water tank of solar water heater is provided, thereby can be according to actual needs, the utilization mechanical system is carried out appropriate regulation to the last water yield and the water temperature of storage tank.

The technical solution of the utility model is by the overflow passage of storage tank is realized by the fixed formula that moves up and down that changes into.

The composition of this overflow air-breather comprises the rigid conduit of a two ends band opening, this rigid conduit is placed up and down, one end opening places in the storage tank (or be complementary with storage tank, communicating pipe of similar liquid level gauge) (forming built-in end), and other end opening places storage tank (or communicating pipe) outer (forming external end); The hole that it is characterized in that rigid conduit directly or indirectly subsidiary with storage tank (or communicating pipe) matrix (promptly subsidiary by intermediate piece) adopts socket joint movable sealing mode to connect.

Because rigid conduit is to adopt socket joint movable sealing mode to connect with storage tank (or communicating pipe), has certain frictional force between the two, so it can move up and down and be parked in a definite position.After the position of rigid conduit was determined, the position of its built-in end opening (overflow passage) was also just decided; So, when the water level in the storage tank rises to and surpass above-mentioned opening to a certain extent, water will overflow and is gone out (because of rigid conduit is placed up and down, be that upper end open placed in storage tank or communicating pipe) or pressurized and going out (because of rigid conduit is placed up and down, be that lower ending opening placed in storage tank or communicating pipe), flow to outside the storage tank (or communicating pipe).This sends a signal beyond doubt, and promptly the water level in the storage tank has reached certain height.As long as do a little corresponding work again, for example: close water supply valve; Or connect a pipe at the external end opening of rigid conduit place again, and be connected (certainly, the upper hose of the full Self closing valve of water also should be connected with running water pipe) with the signal pipe of the full Self closing valve of water, can realize that so manual Shang Shui, water are completely from the semiautomatic control of closing.

Obviously, thus the utility model is by the control of water storage tank water level being realized to the control of the water yield on the storage tank.

Unquestionable, after storage tank was loaded onto above-mentioned overflow air-breather, its beneficial effect (comprising direct and indirect) was many-sided:

1, makes the last water yield of storage tank and water temperature adjustable within the specific limits, thereby strengthened solar water heater's applicability.For example: winter or cloudy weather can obtain the higher hot water of temperature (method is to reduce to go up the water yield); Summer or fine weather can be controlled at water temperature reduced levels (method is to increase to go up the water yield), water heater is moved at lower temperature, thereby can reduce heat waste, and slow down storage tank and heat collector encrustation; Moreover, also can avoid during bathing scalding.

2,, under non-electric prerequisite, realize semiautomatic control that storage tank is quantitatively gone up water, when safety, joint, save worry relatively more suitable China's actual conditions with the full Self closing valve coupling of water.
