Abstract
The utility model belongs to valves, in particular to a water inlet solenoid valve comprising a case, a solenoid and an internal sleeve, wherein, the case is provided with a seal ring bracket and seal rings separating the case into an inlet chamber, a back pressure chamber and an outlet chamber, the seal ring bracket is provided with middle and side orifices. The utility model is characterized in that: the water inlet inside the case is provided with a cylinder, and the cylinder is provided with a stainless steel needle which is just positioned under the side orifice of the seal ring bracket and which goes through the seal ring and the side orifice of seal ring bracket till the back pressure chamber; the diameter of the stainless steel needle is smaller than that of the side orifice of seal ring bracket. Since the addition of the stainless steel needle which can go through the side orifice of seal ring bracket, the utility model can effectively prevent dirt from accumulating around the side orifice and avoid failures caused by the blockage of the side orifice of the water inlet solenoid valve.
Description
Technical field
The utility model belongs to valve type, specifically is a kind of entering water electromagnetic valve.
Background technique
The electromagnetic valve structure compactness, control is convenient, uses extensively, is usually used in the water inlet control of numerous household appliances such as washing machine, air conditioner, dishwasher, ice making machine.General entering water electromagnetic valve comprises housing and the electromagnetic coil that is used to control, interior cover is arranged in the electromagnetic coil, be equipped with spring in the interior cover, iron core, rubber core, seal ring frame and seal ring are installed in the housing, housing is divided into intake chamber, back pressure chamber, water-supplying chamber, be equipped with mesopore and lateral opening on the seal ring frame, when solenoid valve is opened, move on iron core and the rubber core, the water of intake chamber is from the lateral opening inflow back pressure chamber of seal ring frame, the water of back pressure chamber flows out by mesopore, for making seal ring and seal ring frame be in the position of raising all the time, then the lateral opening of seal ring frame must be less than mesopore, and mesopore is limited by the mechanical structure design limit of solenoid valve, the aperture can not be done too greatly, so lateral opening pore size also is restricted.Because the seal ring frame is lateral opening less, and contains a spot of impurity in the water of tap water, the impurity obstruction that takes place easily in the water is lateral opening, thereby causes inlet valve can not effectively to be closed under opening state, and solenoid valve was lost efficacy.
Summary of the invention
The purpose of this utility model is the deficiency at existing technology, and the entering water electromagnetic valve of the lateral opening difficult obstruction of a kind of inlet valve, more reasonable structure, performance safety and reliability is provided.
The technical solution of the utility model is as follows:
A kind of entering water electromagnetic valve, comprise housing and the electromagnetic coil that is used to control, interior cover is arranged in the electromagnetic coil, be equipped with spring in the interior cover, iron core, rubber core, seal ring frame and seal ring are installed in the housing housing is divided into intake chamber, back pressure chamber, water-supplying chamber, be equipped with mesopore and lateral opening on the seal ring frame, there is water intake the housing side, the housing central lower is provided with water outlet, it is characterized in that: housing inner chamber water inlet is provided with a cylinder, and a stainless pin is arranged on the cylinder, and the stainless pin position just in time is positioned at the lateral opening below of seal ring frame, and passing the lateral opening of seal ring and seal ring frame up to back pressure chamber, the stainless pin diameter is less than the lateral opening aperture of seal ring frame.
The utility model is owing to increase by on housing can penetrate the lateral opening stainless pin of seal ring frame, when inlet valve opens and closes, can cause moving up and down of seal ring frame, and stainless pin just in time penetrates the lateral opening of seal ring frame, in the process that moves up and down, can effectively prevent the accumulation of impurity on lateral opening, in addition, also can prevent the absorption of bulk impurity on lateral opening, thereby can effectively prevent the obstruction of seal ring frame, also effectively prevent the inefficacy that entering water electromagnetic valve causes because of lateral opening obstruction.The utility model is simple in structure, reliable performance.

Fig. 2 is a housing inner-cavity structure schematic representation.
Embodiment
As Fig. 1, shown in 2, a kind of entering water electromagnetic valve, the electromagnetic coil 2 that comprises housing 1 and be used to control, cover 3 in having in the electromagnetic coil 2, be equipped with spring 4 in the interior cover 3, iron core 5, rubber core 6, seal ring frame 7 and seal ring 8 are installed in the housing 1, housing 1 is divided into intake chamber 15, back pressure chamber 14, water-supplying chamber 16, be equipped with mesopore 11 and lateral opening 12 on the seal ring frame 7, there is water intake housing 1 side, housing 1 central lower is provided with water outlet, it is characterized in that: housing 1 inner chamber water inlet is provided with a cylinder 9, and a stainless pin 10 is arranged on the cylinder 9, and stainless pin 10 positions just in time are positioned at the below of seal ring frame 7 lateral opening 12, and pass seal ring 8 and seal ring frame 7 lateral opening 12 up to back pressure chamber 14, the stainless pin diameter is less than the aperture of seal ring frame lateral opening 12.
During 2 outages of the utility model electromagnetic coil, iron core 5 and rubber core 6 are subjected to spring 4 pressure effects and press down, with seal ring 8, seal ring frame 7 toward pressing down and by mesopore 11 sealings of rubber core 6 with seal ring frame 7, this moment, seal ring 8 cut off the traffic channel of intake chamber 15 with drip chamber, valve is in closed condition, the water of intake chamber 15 enters into back pressure chamber 14 by lateral opening 12 of seal ring frame 7, and the propagation of pressure of intake chamber 15 is in back pressure chamber 14, and back pressure chamber equates with the pressure of intake chamber 15.And because the pressure of water-supplying chamber 16 does not have, then the last applanation of seal ring 8 is greater than the pressure of lower plane, thereby makes seal ring 8 being pressed on the water shutoff mouth 13 tightly, and valve is in closed condition all the time.
During 2 energisings of the utility model electromagnetic coil, by the effect in magnetic field, iron core 5 is attracted and pressure spring 4, thereby iron core 5 is moved up, original sealed seal ring frame 7 mesopores 11 are opened, and the high pressure water in the back pressure chamber flows in the water-supplying chamber 16 by seal ring frame 7 mesopores 11 and discharges inlet valve; After part water is discharged from the back pressure chamber, the pressure of back pressure chamber reduces, the pressure ratio back pressure chamber of intake chamber 15 is big, thereby seal ring 8, seal ring frame 7 are up moved, seal ring 8 separates with housing 1 water shutoff mouth 13, intake chamber 15 is communicated with water-supplying chamber, and the water inlet of valve directly flows to water-supplying chamber from intake chamber 15 and discharges housing 1, thereby inlet valve is opened.
The utility model has increased by a stainless pin 10 of lateral opening 12 that can penetrate seal ring frame 7 on housing 1, when inlet valve opens and closes, can cause moving up and down of seal ring frame 7, and stainless pin 10 just in time penetrates the lateral opening of seal ring frame, in the process that moves up and down, can effectively prevent the accumulation of impurity on lateral opening.
Housing of the present utility model is a plastic casing 1, together with the stainless pin injection moulding, finishes the fixing of stainless pin when plastic casing 1 injection moulding.
The utility model can be widely used in the water inlet control of numerous household appliances such as washing machine, air conditioner, dishwasher, ice making machine.
