Description
Technical Field
The invention relates to the field of hardware, in particular to a three-way valve.
Background
In daily life, a water heater is often used for supplying hot water; however, in the using process, due to the fact that a part of cold water exists in the pipeline from the water heater to the hot water faucet and the reason that the water heater needs time for heating, when the hot water faucet is opened, the hot water faucet always begins to output the cold water for a period of time; if the container is left alone, the cold water is wasted, and if the container is used to take away the cold water for other purposes, it is very troublesome for the user.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a magnetic three-way valve that can determine the temperature of inlet water and rapidly switch the outlet pipes so that cold water and hot water are respectively output from different outlet pipes.
The technical scheme adopted by the invention for solving the technical problems is as follows: the magnetic three-way valve comprises a liquid storage cavity; the liquid storage cavity is filled with expansion with heat and contraction with cold; a thin tube with a closed end is arranged on one side of the liquid storage cavity, and a fixed magnetic block magnetized along the axial direction of the thin tube is arranged at the closed end of the thin tube; a ferromagnetic sliding block is attracted below the fixed magnetic block; a permanent magnet piston is arranged at the liquid level of the expansion and contraction liquid in the thin tube, the permanent magnet piston is magnetized along the axial direction of the thin tube, and the magnetism of the permanent magnet piston is stronger than that of the fixed magnetic block; the permanent magnet piston axially moves in the tubule along with the expansion and contraction of the expansion and contraction liquid; a cold water outlet close to the permanent magnet piston and a hot water outlet close to the fixed magnetic block are arranged on the pipe wall of the thin pipe between the permanent magnet piston and the fixed magnetic block; a water inlet is arranged between the cold water outlet and the hot water outlet; the ferromagnetic slide block is constrained to slide between the cold water outlet and the hot water outlet, blocking the cold water outlet in a first extreme position and blocking the hot water outlet in a second extreme position; when the temperature of the expansion and contraction liquid is lower than the design temperature, the permanent magnet piston is far away from the first limit position of the ferromagnetic sliding block, and the magnetic attraction force of the fixed magnetic block to the ferromagnetic sliding block is larger than the magnetic attraction force of the permanent magnet piston to the ferromagnetic sliding block, so that the ferromagnetic sliding block is pulled to the second limit position; when the temperature of the expansion and contraction liquid is higher than the design temperature, the permanent magnet piston reaches a first limit position of the ferromagnetic slide block, and at the moment, the permanent magnet piston pulls the ferromagnetic slide block to the first limit position; when the ferromagnetic slide block is positioned at the first limit position and the second limit position, the ferromagnetic slide block does not shield the water inlet, and the water inlet is communicated with a hot water pipe of a hot water supply system through a heat exchange pipe penetrating through the liquid storage cavity.
Preferably, the expansion and contraction liquid in the liquid storage cavity is kerosene or mercury, the thermal expansion coefficient is higher, and the phenomena of expansion and contraction are obvious.
Preferably, the ferromagnetic sliding block is constrained to slide between the cold water outlet and the hot water outlet by the fixed magnetic block and a limit convex ring manufactured on the inner wall of the thin tube. Further, the thin tube is made of copper, and the limit convex ring is made of iron; therefore, when the interval exists between the permanent magnet piston and the limiting convex ring, the isolation effect of the limiting convex ring is achieved, the magnetic attraction of the permanent magnet piston to the ferromagnetic sliding block is always kept at a weaker level, and when the permanent magnet piston abuts against the limiting convex ring, the limiting convex ring and the permanent magnet piston are integrated, so that the magnetic field above the limiting convex ring is greatly enhanced, and the magnetic attraction of the permanent magnet piston to the ferromagnetic sliding block is changed suddenly; therefore, the ferromagnetic sliding block can be transferred between the first limit position and the second limit position only by enabling the permanent magnet piston to have a smaller axial movement range, and therefore the switching of the cold and hot water ports has higher sensitivity for the designed temperature.
Preferably, the cross-sectional area of the thin tube is 1/20-1/10 of the cross-sectional area of the liquid storage cavity parallel to the cross section of the thin tube, so that the permanent magnet piston in the thin tube can be pushed to form large-distance axial displacement by the volume change of the liquid storage cavity with small proportion of expansion with heat and contraction with cold.
The invention has the beneficial effects that: when the magnetic three-way valve is used, if the temperature of inlet water is lower than the design temperature, the temperature of expansion with heat and contraction with cold in a liquid storage cavity is reduced through heat conduction to form a smaller volume, so that the permanent magnet piston is far away from the first limit position, the ferromagnetic slide block is attracted to the second limit position by the fixed magnetic block positioned at the end part of the thin tube to block a hot water outlet, and the inlet water can only flow out of a cold water outlet and enter an external cold water recovery system; if the water inlet temperature is higher than the design temperature, the liquid product expanded due to heat expansion and cold contraction in the liquid storage cavity pushes the permanent magnet piston to the first limit position of the ferromagnetic slide block, the ferromagnetic slide block is attracted to the first limit position to block the cold water outlet, and at the moment, the inlet water only can flow out from the hot water outlet; this magnetism is inhaled formula three-way valve can be according to the cold and hot automatic switch-over outlet conduit of intaking, and when it adorns in hot water pipeline, can draw cold water recovery system with the cold water of hot water tap output when just opening, avoids extravagant, makes hot water tap go out water simultaneously and is hot water, saves the process of probing the temperature, provides convenience for the user.
