The mechanical controller for the water intaking quantity of non-bearing water tank in solar water heater includes tubular assembly and rigid ord assembly. The vertically set tubular assembly with upper opening inside the water tank and lower opening outside the water tank features its middle flexible and/or telescopic section and has its upper end connected with the rigid ord assembly extending beyond the water tank and capable of being moved up and down. The controller can control the water intaking quantity and water temperature and this strengthens the adaptability of the solar water heater. The solar water heater can obtain hot water with relatively high temperature in winter or cloudy day and operate at relatively lower temperature in winter or sunny day to reduce heat loss and scale and avoid scalds.

Description

The control device of the water yield on a kind of adjustable solar water heater's storage tank

Technical field

The present invention relates to the non-bearing water tank of a kind of solar water heater of being used for and can measure the mechanical control device of regulation and control water on it (adding water).

Background technology

At present, the used non-bearing water tank of commercially available solar water heater mostly is constant volume type (capacity is fixed, and can not adjust) greatly, and its overflow passage also is fixed.Under non-electric prerequisite, be difficult to use mechanical system that the water yield on it is regulated and control in other words hardly.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.

Summary of the invention

Purpose of the present invention is exactly in order to overcome the above-mentioned deficiency of prior art, and a kind of mechanical control device that can regulate and control the water yield on the non-bearing water tank of solar water heater is provided.Thereby can under non-electric prerequisite, the last water yield and the water temperature of storage tank suitably be controlled according to actual needs.

Technical scheme of the present invention is by the overflow passage of storage tank is realized by the fixed formula that moves up and down that changes into.

But the composition of this control device comprises the tubular module and a rigid bar of two ends band opening, inner chamber admittance fluid.This tubular module is placed up and down, upper end open places in the storage tank (or be complementary with storage tank, communicating pipe of similar liquid level gauge) (forming external end), its lower end matrix along periphery and above-mentioned storage tank (or communicating pipe) bottom matrix directly or indirectly (promptly passing through intermediate piece) sealed engagement together; It is characterized in that: have one section to have flexibility between the tubular module upper and lower end opening or/and the interlude of retractility; The tubular module upper end links with rigid bar, this rigid bar passes from the hole of storage tank (or communicating pipe) upper base directly or indirectly subsidiary (promptly subsidiary by intermediate piece), expose storage tank (or communicating pipe) outer (formation exposed junction), and keep certain frictional force with the entity in the hole of containing it.

Since rigid bar with have flexibility or/and the tubular module of retractility links, so the opening (overflow passage) that it can drive tubular module upper end moves up and down; Because rigid bar has certain frictional force with the entity in the hole of containing it, so it can be parked in a definite position.After the position of rigid bar was determined, the position of tubular module upper end open was also just decided; So, when the water level in the storage tank rose to above-mentioned opening, water went out with regard to the beginning overflow, flows to storage tank (or communicating pipe) outside.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 present invention 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 control device, 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 slow down storage tank and heat collector encrustation; Moreover, also can avoid scalding.

2, the open to atmosphere opening of this control device is positioned at storage tank (or communicating pipe) bottom, can reduce heat waste (water heater also can reduce heat waste in the lower temperature operation).

3,, 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.
