Description
Technical field
The utility model relates to a kind of water supply installation, particularly a kind of water supply installation of automatic control cistern water level.
Background technology
Cistern water level such as solar water heater, drinking water boiler generally adopts water control valve control, needs to install the overflow pipe of high water tank more than 30 centimetres, and water level improves and can produce certain pressure to water tank, causes the water tank seepage easily, shortens the water tank life-span; In the winter of cold, overflow pipe is too high, and the interior water of pipe can not stop up owing to freezing not change, and causes that water tank is ventilative not smooth, causes water heater to be shone the one's water breaks case that rises that generates heat by the sun.Water control valve generally is installed in the water inlet below the water tank, during installation, can regulate after waiting full-water level, and water level is regulated to be needed to wait for a long time, installs and regulates inconvenience; Water control valve changes with the variation of hydraulic pressure, and unstable properties can cause the sealing ring compressive strain to leak because of hydraulic pressure is too high; When single tube was installed, hot water circulated from water control valve, also had the too little shortcoming of flow.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing water control valve exists, problem to be solved in the utility model provide a kind of simple and compact for structure, the water tank automatic water supply device of little, stable performance easy to adjust, affected by environment, long service life is installed.The technical scheme that its technical problem that solves the utility model adopts comprises casing, case lid, case lid is fixed on the end face of casing, the bottom surface of casing is provided with water inlet, the sidewall of casing is provided with delivery port, the box inside corresponding with water inlet is provided with valve seat, be fixed with valve body on the valve seat, be provided with piston in the valve body, piston is provided with the diaphragm seal corresponding with the valve seat inlet opening, be connected with bar on the valve body, the road bar is provided with floating drum, is hinged with lever on the valve body, one end of lever cooperates with piston, and the other end is connected with floating drum by connecting rod.
In order to guarantee the water source quality, described casing water inlet is provided with screen pack.
In order to improve air permeable effect, described case lid is provided with air-vent.
After adopting said structure, when water level was higher than the delivery port water level, floating drum upwards floated, and floating drum rotates by the connecting rod pull lever, and the lever pushing piston moves downward, and makes diaphragm seal push down the valve seat inlet opening, closes into water; When water level was lower than the delivery port water level, floating drum was removed the water inlet of valve seat inlet opening by connecting rod, lever drives piston and diaphragm seal; Have that compact conformation is reasonable, easy to install, advantage such as stable performance, not affected by environment, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, specific embodiments for a kind of water tank automatic water supply device of the utility model, it comprises casing 5, case lid 1, case lid 1 is fixed on the end face of casing 5, case lid 1 is provided with air-vent 2, the bottom surface of casing 5 is provided with water inlet 11, described water inlet 11 is provided with screen pack 10, the sidewall of casing 5 is provided with delivery port 13, casing 5 inboards corresponding with water inlet 11 are provided with valve seat 9, are fixed with valve body 6 on the valve seat 9, are provided with piston 7 in the valve body 6, piston 7 is provided with the diaphragm seal 8 corresponding with valve seat 9 inlet openings, be connected with bar 3 on the valve body 6, road bar 3 is provided with floating drum 4, and lever 14 is hinged on the valve body 6 by fulcrum 15, one end of lever 14 cooperates with piston 7, and the other end is connected with floating drum 4 by connecting rod 12.
The course of work of the present utility model is as follows: when cistern water level is higher than delivery port 13 water levels, floating drum 4 upwards floats, and floating drum 4 rotates by connecting rod 12 pull lever 14, and lever 14 drives piston 7 and moves down, make diaphragm seal 8 push down valve seat 9 inlet openings, close into water; When cistern water level was lower than delivery port 13 water levels, floating drum 4 buoyancy reduced, and floating drum 4 moves down lever 14 by connecting rod 12, and lever 14 drives piston 7 and moves up, and diaphragm seal 8 is removed valve seat 9, and valve seat advances the water inlet of 9 water holes; Thereby reach the purpose of automatic water-supply.
