Description
Technical field
The utility model relates to valve, relates in particular to a kind of solenoid valve that is used for domestic water purifying machine.
Background technique
Along with expanding economy, the trend that water resources situation worsens has appearred in many places, and shortage of water resources and pollution are more and more serious, and city dweller's drinking water safety problem highlights.At the secondary pollution problem of city tap-water and because source water pollutes the harmful matter that renews in tap water, more and more be that the domestic water purifying machine of core filter element enters huge numbers of families with the reverse osmosis membrane.Existing domestic water purifying machine is to be the core filter element with the reverse osmosis membrane, through after the multistage pretreatment and supercharging to tap water, enters reverse osmosis membrane unit again, the pure water that produces can meet the drinking water standard of developed country fully.
In the family expenses water purification machine, the structure of existing solenoid valve generally comprises valve body, be provided with in the valve body and water-inlet cavity, water chamber, water-inlet cavity, water chamber are connected with water intake, water outlet respectively, electromagnetic control assembly comprises the water shutoff assembly that is arranged on water chamber lower end mouth position, and driving water shutoff assembly moves back and forth the execution member that water chamber, water-inlet cavity are changed under connection, blocking-up two states.The switching state of existing solenoid valve is by after the energising, passes the magnetic bar and moves under the coil block the action of a magnetic field, and the water shutoff assembly comes the switching state of control electromagnetic valve in the black box thereby drive.But this solenoid valve is after outage disconnects, and particularly under the situation that the water chamber side hydraulic pressure is higher after the disconnection, the water-inlet cavity side hydraulic pressure is lower, solenoid valve can produce the situation that water adverse current or solenoid valve can't disconnect fully.
The model utility content
Technical problem to be solved in the utility model provides the solenoid valve that water can not produce adverse current, can disconnect fully in a kind of rear electromagnetic valve that cuts off the power supply.
The technical scheme in the invention for solving the above technical problem is: solenoid valve, comprise valve body, be provided with in the valve body and water-inlet cavity, water chamber, water-inlet cavity, water chamber are connected with water intake, water outlet respectively, electromagnetic control assembly comprises the water shutoff assembly that is arranged on water chamber lower end mouth position, reach driving water shutoff assembly and move back and forth the execution member that water chamber, water-inlet cavity are changed under connection, blocking-up two states, be provided with the check diaphragm unit of water route between described water chamber and water outlet by water chamber single flow direction water outlet.
Working principle of the present utility model is: solenoid valve is when energising, and electromagnetic control assembly control water chamber, water-inlet cavity are in the state of connection, normally circulates in the assurance water route.When solenoid valve cuts off the power supply, electromagnetic control assembly control water chamber, water-inlet cavity are in the state of blocking-up, even this moment, the hydraulic pressure at water outlet place was higher, greater than the hydraulic pressure in the water chamber, owing between water chamber and water outlet, be provided with the check diaphragm unit of water route by water chamber single flow direction water outlet, water can not produce the adverse current phenomenon yet in the solenoid valve, has further guaranteed the Security and the reliability of solenoid valve work.
Described check diaphragm unit comprises connecting rod, gusset, unidirectional water shutoff diaphragm are sleeved on the connecting rod or with connecting rod and are structure as a whole, constitute flow channel between gusset and valve body, the outer periphery protrusion that gusset is positioned at the water chamber side forms the screens projection, with the clamping of flow channel water chamber side outer rim; Unidirectional water shutoff diaphragm constitutes water chamber under flow action, water outlet is being communicated with, is blocking the seal membrane of changing under the two states.
Described unidirectional water shutoff diaphragm is disc-shaped diaphragm or water shutoff ring plate.
Described unidirectional water shutoff diaphragm protrudes to the water chamber side.
To sum up, the beneficial effects of the utility model are: solenoid valve of the present utility model is provided with the check diaphragm unit of water route by water chamber single flow direction water outlet between water chamber and water outlet, therefore the interior water of rear electromagnetic valve that cuts off the power supply can not produce adverse current, and solenoid valve can disconnect fully.
