Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Referring to fig. 1 to 3, the dual-spool magnetic three-way valve includes a valve seat 2, the valve seat 2 has three valve ports 1, the valve seat 2 further has two valve cavities 12, the two valve cavities 12 are disposed between different valve ports 1, and a valve cover 4 is disposed at a mouth of each valve cavity 12; a cylindrical supporting part 13 extending towards the opening part direction of the valve cavity 12 is arranged in the center of the valve cavity 12, a partition plate 11 is arranged among the opening part of the cylindrical supporting part 13, the opening part of the valve cavity 12 and the valve cover 4, and through-flow holes 3 are respectively formed in the partition plate 11 corresponding to the inner side and the outer side of the cylindrical supporting part 13; the center of the valve cover 4 is provided with an outward bulge part 5, a push rod 6 is arranged in the bulge part 5 in a sliding way, the tail end of the push rod 6 is provided with a spring 7, and the front end of the push rod 6 is fixedly provided with a colloid 10 and is opposite to the overflowing hole 3 in the center of the partition plate 11; the valve seat 2 is provided with an electromagnetic generator 8 corresponding to the valve cover 4.

When the electromagnetic generator 8 is in a power-off state, the push rod 6 is pushed by the spring 7 at the tail end to push the colloid 10 at the front end against the partition plate 11, so that the overflowing hole 3 in the center of the partition plate 11 is sealed. When the electromagnetic generator 8 is electrified, an electromagnetic field is generated, and acts on the push rod 6, so that the push rod 6 slides against the pressure of the spring 7 at the tail end of the push rod, the colloid 10 is driven to be separated from the partition plate 11, and the closing of the overflowing hole 3 in the center of the partition plate 11 is released.

Further, the electromagnetic generator 8 is fixed to the valve seat 2 by screws, and the valve cover 4 is pressed and fixed to the valve seat 2 by a housing 9 of the electromagnetic generator 8.

Further, the cylindrical support portion 13 is integrally formed with the valve seat 2, simplifying assembly of the valve.

Further the colloid 10 is the plug of frustum shape, and it inserts the cooperation with the discharge orifice 3 at baffle 11 center, and the structure of frustum shape makes its slight wearing and tearing take place the back, still can seal with discharge orifice 3, and life is longer.

Further under the power-off state of the electromagnetic generator 8, the colloid 10 is in sealing fit with the partition plate 11, and the overflowing hole 3 in the center of the partition plate 11 is sealed. The valve is mostly in a closed state in a normal state, so the scheme can reduce the electrifying time of the coil of the electromagnetic generator 8, thereby saving electric energy and prolonging the service life of the electromagnetic generator.

The double-valve-core magnetic control three-way valve controls the gating state of the valve through two electromagnetic generators 8. The respective states thereof are explained below with reference to fig. 4 to 7:

referring to fig. 4, when both of the two electromagnetic generators 8 are de-energized, the central overflow holes 3 of the partition plates 11 in the two valve cavities 12 are both sealed by the colloid 10. At this time, the water flow path is as shown by the dotted line with an arrow in fig. 4, the water flow is blocked by the two colloids 10, and the three-way valve is in a closed state.

Referring to fig. 5, when the electromagnetic generator 8 on the upper left side is de-energized and the electromagnetic generator 8 on the lower right side is energized, the central overflow hole 3 of the partition plate 11 in the valve cavity 12 on the upper left side is closed by the colloid 10, and the colloid 10 in the valve cavity 12 on the lower right side is separated from the overflow hole 3 in the center of the partition plate 11, at this time, the valve port 1 on the left side and the valve port 1 on the right side enter a communicating state, and are still in a closed state with the valve port 1 on the rear side, and the water flow path is shown by the dotted line with an arrow in fig. 5.

Referring to fig. 6, when the electromagnetic generator 8 on the upper left side is powered on and the electromagnetic generator 8 on the lower right side is powered off, the colloid 10 in the valve chamber 12 on the upper left side is separated from the overflow hole 3 in the center of the partition plate 11, and the colloid 10 in the valve chamber 12 on the lower right side closes the overflow hole 3 in the center of the partition plate 11, at this time, the valve port 1 on the left side and the valve port 1 on the rear side enter a communicating state, and are in a closed state with the valve port 1 on the right side, and the water flow path is shown by the dotted line with an arrow in fig. 6.

Referring to fig. 7, when both the electromagnetic generators 8 are powered, the colloid 10 in both the valve cavities 12 is separated from the overflow hole 3 corresponding to the center of the partition 11, and at this time, the left valve port 1 is in a communication state with the right valve port 1, the left valve port 1 and the rear valve port 1, and the water flow path is shown by the dotted line with an arrow in fig. 7.

Therefore, the double-valve-core magnetic control three-way valve controls the conduction state of the three-way valve through the two electromagnetic generators 8.
