Background
Salt suction devices, or salt valves, used in currently known demineralized water treatment apparatuses basically have two structures, one of which is an air check valve structure; and the other is a combination of an air check valve and a liquid level control valve. Both of these structures have the following drawbacks: it does not have the function of regulating and controlling the quantity of the sucked saline water, so that the consumption of the saline water cannot be accurately controlled.
Disclosure of Invention
In order to overcome the defect that the prior salt absorber does not have the function of regulating and measuring the quantity of sucked salt water, the invention provides a double-liquid-level control salt absorber, which effectively solves the defects of the prior salt absorber.
The technical scheme adopted for solving the technical problems is as follows: two valves, namely an upper liquid level control valve and a lower liquid level control valve, are arranged on a salt water passage of the salt suction device; the valve clack action of the valve is driven by a floater; the valve clack and the floater are connected by adopting a glass fiber reinforced plastic rod; all sealing is realized by adopting a rubber ring or a rubber pad; the valve body is formed by injection molding of engineering plastics; the two valve bodies and the water inlet and outlet guide pipes are bonded by sealant; the float is positioned in a sliding locking mode by a rubber ring. Thus, the manufacture of the double-liquid-level control salt absorber is completed.
Compared with the existing salt absorber, the double-liquid-level control salt absorber has the function of regulating and controlling the brine volume, so that the salt consumption of a softened water system can be accurately controlled, and the problem of salt consumption of the softened water system, which is plagued for a long time, is solved.

Detailed Description
In fig. 2, the upper liquid level control valve (1), the lower liquid level control valve (2), the squirrel-cage upper liquid level valve cover (3), the squirrel-cage lower liquid level valve cover (4), the water inlet and outlet interface (6), the upper liquid level float (8), the lower liquid level float (9), the upper valve clack (14) and the lower valve clack (16) are all formed by injection molding engineering plastics; a float lower positioning rubber ring (11), a float upper positioning rubber ring (12), an upper valve sealing rubber ring (13), a lower valve top sealing rubber ring (15) and a lower valve bottom sealing rubber ring (17) are all made of rubber in a customized mode; the water inlet and outlet conduit (5) is made of a universal UPVC plastic pipe; the float rod (10) is made of a customized glass fiber reinforced plastic rod; the connection between the upper liquid level control valve (1) and the lower liquid level control valve (2) and the water inlet and outlet pipe (5) and the water inlet and outlet interface (6) adopts an adhesive mode.
The specific functions of the invention are realized as follows: in the process of injecting clear water, when water flow enters a cavity of the lower liquid level control valve (2) from the water inlet and outlet connector (6) through the water inlet and outlet conduit (5), the lower valve clack (16) is jacked up from the lower valve bottom sealing rubber ring (17), and the lower valve clack (16) is tightly attached to the lower valve top sealing rubber ring (15) for sealing; the water flow enters the cavity of the upper liquid level control valve (1), the upper valve clack (14) is positioned at the valve bottom, and the water flow flows out of the squirrel-cage upper liquid level valve cover (3) after passing through the upper valve sealing rubber ring (13); the water level rises all the time, the lower liquid level floater (9) is submerged, and the lower valve clack (16) does not act at the moment because the lower valve clack is in a floating position; the water level continues to rise until the upper liquid level floater (8) floats, the upper valve clack (14) is pulled to act, and the upper liquid level floater is tightly attached to the upper valve sealing rubber ring (13) to seal, so that the process of injecting clear water is completed. In the process of sucking out the brine, the suction force firstly enables the upper valve clack (14) to act downwards, and because the lower liquid level floater (9) is in a submerged state and bears larger buoyancy, the upper liquid level floater (8) is in a floating state and bears smaller buoyancy, the upper valve clack (14) can be opened firstly; the brine flows through the upper liquid level control valve (1) and the lower liquid level control valve (2) and flows out through the water inlet and outlet conduit (5) and the water inlet and outlet interface (6); the liquid level of the brine continuously drops until the liquid level is lower than the lower liquid level float (9) to cause the lower valve clack (16) to act downwards, and the lower valve clack is tightly attached to the lower valve bottom sealing rubber ring (17) to be closed, so that the suction process of the brine is completed. The level difference between the upper level float (8) and the lower level float (9) determines the amount of sucked out brine. Normally, the upper level float (8) is set in the highest position so that the most brine can be obtained; the lower liquid level float (9) can be set by sliding and adjusting the lower positioning rubber ring (11) of the float and the upper positioning rubber ring (12) of the float so as to meet the requirement of obtaining the expected brine.
