The utility model provides a technical scheme that above-mentioned technical problem adopted is: the utility model provides a multifunctional electromagnetic valve, including disk seat two, disk seat two is equipped with drainage import and drainage export, be equipped with in the disk seat two and arrange water chamber one, drainage chamber two, and control drainage chamber one, the solenoid valve head of water route switch-on or blocking between the drainage chamber two, drainage import and the switch-on of drainage chamber two, drainage export and the switch-on of drainage chamber one, still include disk seat one, be equipped with former water chamber in the disk seat one, disk seat one is equipped with the raw water import with former water chamber switch-on, former water outlet, disk seat one is connected with disk seat two, it seals to be equipped with the dense water that comprises two bodies of disk seat on the water route of drainage chamber two and drainage export switch-on, and control dense water seals and arranges the water sealing assembly of water route.

The existing household water purification machine system is usually provided with a preposed water cut-off electromagnetic valve independently to control the household water purification machine system not to continuously drain water when the household water purification machine system stops working. The integrated water subassembly that seals that is used for controlling the water route break-make that has set up in the multi-functional solenoid valve of this scheme, seal and arrange the water route between the chamber two and block through control dense water when domestic water purification machine system stop work, prevent that the system from continuing the drainage, play the function of disconnected water solenoid valve, adopt the utility model discloses a multi-functional solenoid valve can practice thrift a most cost of disconnected water solenoid valve, can also reduce its volume that occupies, is convenient for further optimize the overall structure of domestic water purification machine system.

Furthermore, a drainage flow channel communicated with the drainage cavity I is arranged in the valve seat II, the water sealing assembly comprises a sealing assisting spring, a pressing plate and a water sealing diaphragm, the periphery of the water sealing diaphragm is hermetically fixed between the valve seat I and the valve seat II, the sealing assisting spring and the pressing plate are arranged in the raw water cavity, one end of the sealing assisting spring acts on the water sealing diaphragm through the pressing plate, and the other end of the sealing assisting spring acts on the inner wall of the raw water cavity; the water sealing diaphragm controls the connection or the blockage of a water path between the concentrated water seal and the second drainage cavity under the combined action of the water pressure of the drainage channel, the water pressure in the raw water cavity, the elastic force of the sealing-assisting spring and the concentrated water seal.

Among the prior art, also have the technique of setting up the subassembly integration of cutting off the water in the booster pump, the booster pump of cutting off the water promptly, this kind sets up the condition in the booster pump with the structure of cutting off the water, because the pressure boost theory of operation of booster pump can lead to the continuous frequent reciprocating motion between sealed, keeping away from the water sealing mouth of sealing diaphragm of the subassembly of cutting off the water at the during operation, leads to the fact the slapping to the water sealing mouth, and then causes the booster pump of cutting off the water and can last vibrations at the during. The integrated setting of the subassembly that seals of this scheme is in multi-functional solenoid valve, when water purification machine system work is in system water state, the solenoid valve head is out of work and is in the closed condition, control drainage chamber one, the water route blocks between the drainage chamber two, the dense water that produces when reverse osmosis filter group system water passes through the pipeline and flows into in the drainage chamber two with the drainage import switch-on of multi-functional solenoid valve, the effort of water pressure to sealing the diaphragm in the drainage runner with the switch-on of drainage chamber two is greater than the effort of water pressure to sealing the diaphragm in the former water cavity, help when sealing the spring to the effort sum of sealing the diaphragm, seal the diaphragm can keep away from dense water under the combined action of above-mentioned effort and seal, dense water seals through dense water in the drainage runner, the choked flow plug piece, the drainage.
