Abstract
The utility model relates to a multi-functional solenoid valve. The multi-functional solenoid valve comprises a valve body, in which a source water chamber and a flushing water chamber are arranged. The source water chamber and the flushing water chamber are communicated with an inlet and an outlet respectively. The flushing water chamber is communicated with the source water chamber by a pressure release structure. In the multi-functional solenoid valve, as the pressure release structure is positioned between the flushing water chamber and the source water chamber, when the water pressure in the flushing water chamber is higher than the setting water pressure, the pressure release structure is turned on and the high pressure water in the source water chamber flows into the flushing water chamber, thereby avoiding the potential safety hazard caused by over-high water pressure.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of multi-function electromagnetic 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 after 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 does not possess the pressure release function, if feed-water end hydraulic pressure is too high, the assembly of solenoid valve front will bear too high hydraulic pressure and cause potential safety hazard.
The model utility content
Technical problem to be solved in the utility model provides a kind of multi-function electromagnetic valve, and hydraulic pressure is subject to the hydraulic pressure value that sets in this multi-function electromagnetic valve outage back valve.
The technical scheme in the invention for solving the above technical problem is: multi-function electromagnetic valve, comprise valve body, active water cavity, flushing water cavity are set in the valve body, and source water cavity, flushing water cavity are connected with water intake, water outlet respectively, and described flushing water cavity is connected by pressure relief and source water cavity.
Described pressure relief comprises that the pressure release that is made of the valve body body seals, seals the pressure release water shutoff diaphragm that this pressure release is sealed, pressure release water shutoff diaphragm periphery is fixed between valve body and gland, also be provided with the pressure release spring in the cavity that gland and pressure release water shutoff diaphragm form, pressure release spring one end acts on pressure release water shutoff diaphragm by the spring lower bolster, and an end acts on the gland inwall; Move back and forth the pressure relief that constitutes that water route between control source water cavity, flushing water cavity is being connected, changes under the blocking state under the acting in conjunction of described pressure release water shutoff diaphragm hydraulic pressure and pressure release spring in source water cavity, flushing water cavity.In this scheme, when hydraulic pressure in the pressure-releasing chamber surpasses setting value, hydraulic pressure overcomes the active force of pressure release spring to pressure release water shutoff diaphragm to the active force of pressure release water shutoff diaphragm in the pressure-releasing chamber, and pressure release water shutoff diaphragm seals away from pressure release, makes that the water route is connected between source water cavity, flushing water cavity; When hydraulic pressure was no more than setting value in the pressure-releasing chamber, the pressure release spring overcame to the active force of pressure release water shutoff diaphragm that hydraulic pressure is to the active force of pressure release water shutoff diaphragm in the pressure-releasing chamber, and pressure release water shutoff diaphragm seal pressure release is sealed, and made water route blocking-up between source water cavity, flushing water cavity.
Described gland and pressure release spring contacting point are provided with the adjusting element of can regulate pressure release length of spring compressed degree, and pressure release spring upper end acts on the adjusting element lower surface by the spring Upper gasket.Particularly, to be that screw thread is adjustable with gland be connected described adjusting element.The size of the pressure release value that this structure can according to circumstances be adjusted multi-function electromagnetic valve and limited.
The cavity of the corresponding flushing of described pressure-releasing chamber water cavity is provided with secretes discharge orifice, and described multi-function electromagnetic valve also is provided with to insert to be secreted discharge orifice and secrete the flow resistance fluidization tower with this secretes that orifice structure adapts to, described secrete the flow resistance fluidization tower and secrete between the discharge orifice inwall have the gap.
Describedly secrete the flow resistance fluidization tower and pressure release water shutoff diaphragm is structure as a whole.
To sum up, the beneficial effects of the utility model are:
1, multi-function electromagnetic valve of the present utility model is provided with pressure relief between flushing water cavity and source water cavity, pressure relief is opened when hydraulic pressure in the pressure-releasing chamber is higher than setting hydraulic pressure, high-pressure water flow in the water cavity of source is to washing water cavity, can not make pure water machine system bear too high hydraulic pressure, avoid causing potential safety hazard.
2, the utility model is provided with and secretes discharge orifice and the corresponding flow resistance fluidization tower structure of secreting; because multi-function electromagnetic valve is when quitting work; hydraulic pressure in the water cavity of source all can surpass normal pressure (hydraulic pressure that adapts with barometric pressure in the water route when pure water machine system is shut down); this structure is after solenoid valve is quitting work; current can flow out by the gap slowly-releasing of secreting the flow resistance fluidization tower and secrete between discharge orifice in the water cavity of source; hydraulic pressure in the water cavity of reduction source; make the hydraulic pressure in the water cavity of source remain on the normal pressure value; guarantee can not be in the superpressure state after solenoid valve quits work, further reduced potential safety hazard.
