Abstract
The utility model relates to a hydraulic automatic water level controller, comprising a positioning cylinder, a plunger, a spring, a control valve, etc. The plunger and the control valve are connected into a whole. When the water level of a water tank is lower than required water level, a water inlet is opened, and the water tank is filled with water. When the water tank is full of water, the water entering the positioning cylinder presses the plunger and the control valve to the lowest position, and the water inlet is closed or the power supply of a water supplying pump is cut off, so the purpose of automatically closing water supply is achieved. The hydraulic automatic water level positioning device has simple structure, low cost and convenient operation. The utility model is suitable for replacing the floating-ball type automatic device of a water closet or automatically controlling the water level of the water tank.
Description
The utility model is to belong to a kind of equipment that automatic control cistern water level is used.
The device of control cistern water level has several different forms at present, and water level automatic control devices such as float-ball type, electric pole type, condenser type are wherein arranged.All there are some problems in each form, concentrates as the floating ball rod and the control valve tie point stress of float-ball type, damages easily; Electric pole type requires the circuit complexity; Condenser type poor anti jamming capability etc.
The purpose of this utility model be for overcome that the problems referred to above provide a kind of simple in structure, volume is little, cost is low, non-damageable water pressing water level automatic control device.
A kind of water pressing water level automatic control device of controlling cistern water level that the utility model is made up of parts such as positional cylinder 1, piston 3, spring 2 and control valves 4.Its basic functional principle is that control valve 4 is in opening state when cistern water level is lower than on the positional cylinder 1 the locating face height, and the water source send water to water tank.This moment, positional cylinder 1 was interior anhydrous, and piston 3 is in upper under the effect of spring 2, blocks the outlet that positional cylinder 1 leads to water tank.After cistern water level reached locating face, water flowed into positional cylinder 1 until till filling from positional cylinder 1 top.This moment piston 3 and control valve 4 water in positional cylinder 1 the pressure effect under overcome spring force and move downward to the next, the water outlet of positional cylinder 1 is opened, the water in the positional cylinder 1 and the water of water tank are communicated with, when the water source is when supplying water by the direct feed tank of water pipe, 4 water routes that directly cut off in the water pipe of control valve make water tank stop to go up water; When the water source is when supplying water by the water pump feed tank, the power supply in 4 cut-out water pumps of control valve quits work water pump, supplies water thereby stop feed tank.When the water in the water tank is drawn out of, water is also taken away in the positional cylinder 1, make that water pressure reduces on the piston 3, and less than spring force, and piston 3 and control valve 4 are moved upward under the spring force effect, piston 3 and control valve 4 are in upper again, piston 3 is blocked outlet, control valve 4 is opened the water source to cistern water supply by water route or circuit, until fill water tank, reaches the locating face height, water flows into positional cylinder 1 from locating face, after positional cylinder 1 is filled, again piston 3 and control valve 4 are pressed to the nextly by hydraulic pressure, close the water source automatically.
The utility model has following advantage: (1) is simple in structure, and cost is low; (2) reliable operation, structure are not fragile; (3) volume is little, and the water tank profile is not had specific (special) requirements, is convenient to the change of water tank profile.
Description of drawings: accompanying drawing is a kind of structural drawing of the present utility model.
The utility model embodiment: the utility model embodiment is the water pressing water level automatic control device of water tank in a kind of flush toilet.It is made up of parts such as positional cylinder 1, piston 3, spring 2, control valve 4 and connecting tubes 5, each parts all forms with plastic injection-moulded, positional cylinder 1 is connected with connecting tube 5 usefulness screws, piston 3 and control valve 4 fuse, piston 3 is in positional cylinder 1, control valve 4 can move up and down in connecting tube, and spring 2 is between piston 3 and positional cylinder 1.When water tank was anhydrous, piston 3 and control valve 4 upwards moved to upper under the spring force effect, and piston 3 is blocked the water outlet of positional cylinder 1, and the water route is obstructed between positional cylinder 1 and the water tank, and control valve 4 is opened the water intake of connecting tube 5, and the water source is to cistern water supply; When cistern water level reaches locating face, water enters positional cylinder 1 from positional cylinder 1 top, until till filling, at this moment, piston 3 is subjected to effect of water pressure, and overcoming spring force, that piston 3 and control valve 4 are moved downward to is the next, and control valve 4 is blocked the water intake of water tank, stop feed tank and supply water, reach the water level purpose of control automatically.
Claims (1)
1, a kind of water pressing water level automatic control device, be contained between water tank and the water source, link to each other by control valve, it is characterized in that it being to fuse by positional cylinder [1], spring [2], piston [3] and control valve [4], piston [3] moves up and down in positional cylinder [1], spring [2] is between positional cylinder [1] bottom and piston [3], and control valve [4] manipulation water source is to the unlatching of cistern water supply or close.
