Abstract
The utility model relates to a diaphragm valve which automatically controls water level. The utility model adopts the electromagnetic mechanical control which is integrated in the same valve and is opened and closed by pipeline pressure. A lever end on the valve is connected with a water level floating ball by a rope. The weight of the floating ball is passed to the lever flange through gravity so as to press a gag bit of an electromagnet and drive a pressure relief device. The diaphragm valve enables the upper and lower cavities of the diaphragm to produce pressure difference to drive the diaphragm to open and close the valve through the pressure relief device. The mechanical part automatically opens the valve in low water level. Water supply peak at daytime is avoided and at night a time relay controls the electromagnet to open the valve. The circuit is cut off by a limit switch to close the valve in the maximum water level. The valve simplifies the controlling and installation, guarantees normal water supply and can be used as liquid level control for other media.
Description
The utility model is the invention about automatic control water level valve.Existing control water level has electromagnetism, Electric Traction and mechanically controlled valve door to realize, how current collection control and machine control be in the valve that same valve, depended on pressure open and close, and simplifies control and installs, and guarantees normal water supply, is to supply water to need the problem that solves.
The purpose of this utility model is: provide a kind of simple in structure, current collection magnetic, machinery to be controlled in the diaphragm valve that same valve, tube road pressure open and close.
Its solution is: adopt the armature that machinery and electromagnet can DM, common forming control system and pressure relief device, diaphragm valve, the automatic controlling diaphragm plate valve of formation water level.
Accompanying drawing has been described the utility model embodiment's structural representation and has been represented that by Fig. 1 and Fig. 2 their working principle is identical, and for sake of convenience, only just Fig. 1 elaborates, and Fig. 2 only points out the structure difference with Fig. 1.
Shown in Figure 1, flange (12) on lever (11), the lever, counterweight (10), be contained in lever hinge bearing (9) on the valve body, rope (21) connect lever (11) end and ball float (22), be fixed on electromagnet (13) and electromagnet armature (14) on the pressure relief device, forming control system jointly.
Spring (7), sealing gasket (8), pressure release nozzle (17), pressure relief opening (15), be contained in output tube (20) inner outlet, constitute pressure relief device along the leak-off pipe (16) that flows out direction.
Primary flow path inlet opening (1), be contained in dish type diaphragm (4) that the interior import in primary flow path inlet opening (1) separates to the flow tube (2) of living inflow direction, nozzle (6), control chamber (5), delivery outlet (3), lower chambers (23) and control chamber (5), cross head piece (19), output tube (20) formation diaphragm main valve.
Decide water level, pass valve when reaching to give: ball float (22) floats on the water surface, counterweight (10) is downward, flange (12) on the lever (11) leaves armature (14), armature (14) is made progress by the thrust of spring (7), the pressure that sealing gasket (8) bars up pressure release nozzle (17), primary flow path inlet opening (1) enters pressure release chamber (18) through flow tube (2), pass through head piece (19) again and enter control chamber (5), produce pressure reduction, disc-shaped diaphragm (4) is closed delivery outlet (3), and valve is turned off.
Decide water level when being lower than to give, drive valve: ball float (22) leaves the water surface, and its gravity makes lever (11) downward by rope (21), flange on the lever (12) presses armature (14) downward, sealing gasket (8) is backed down, push down nozzle (6), at this moment nozzle (17) is opened, pressure in the control chamber (5) enters pressure relief opening (15) through head piece (19), discharge to output tube (20) through relief tube (16) again, produce pressure reduction, disc-shaped diaphragm (4) upwards, open delivery outlet (3), valve is opened.
Electromagnet is controlled by the time relay, avoids the daytime water use peak and supplies water at night, reaches highest water level and cuts off the circuit throttle down by limit switch.
The difference of Fig. 2 and Fig. 1 is: flow tube (2), nozzle (6) are cancelled, primary flow path inlet opening (1) communicates by aperture (24) on dish type diaphragm (4) inclined-plane and control chamber (5), the aperture of aperture (24) is less than the aperture of crossing head piece (19), make the pressure release flow velocity greater than the speed that flows into control chamber (5) by aperture (24), be convenient to form pressure reduction.
This valve can also be used for the liquid level control of other media.
