The implication that technical staff is generally understood that is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein "and/or" includes one or more
The arbitrary and all combination of related Listed Items.
As shown in figure 1, one embodiment of the present invention provides a kind of solenoid check valve, the solenoid check valve includes：Main body
1；The main body 1 is provided with the runner 2 extended in the same direction with it；One end of the main body 1 is provided with the water inlet for being passed through the runner 2
3；The side wall of the main body 1 is provided with the delivery port 4 communicated with the runner 2；Electromagnet 6, Yi Jifa are provided with the runner 2
Core 5；The outer edge surface of the valve element 5 is fitted with the inner wall sealing of the runner 2；The electromagnet 6 is fixed on the inwall of runner 2
Go up and be connected with power supply 8；The material of the valve element 5 is iron or ferroalloy；The electromagnet 6 can attract the valve element 5.
The valve element 5 has the first position and the second place along the bearing of trend of main body 1 spaced a predetermined distance；It is described
Valve element 5 will be blocked when being located at the first position between the water inlet 3 and the delivery port 4, and the valve element 5 is located at described the
The water inlet 3 is connected with the delivery port 4 during two positions；In the valve element 5 towards the water inlet 3 one in the runner 2
Side sets restraining position ring block 7；The spacing ring 7 can prevent the valve element 5 from being moved when being located at the first position to the water inlet 3
It is dynamic.
The valve element 5 can be from the first position to described when being more than the suction of the electromagnet 6 by the pressure of water
Move the second place；The valve element 5 by water pressure be less than the electromagnet 6 suction when can from the second place to
The first position movement.
In the present embodiment, main body 1 can be pipe structure.The material of main body 1 can be metal, such as steel, iron,
The material such as aluminium and metal alloy.Specifically, the cross section of the main body 1 can be toroidal.Valve element 5 constructs for plectane.
Wherein, length of the delivery port 4 along the direction of main body 1 is more than length of the outer edge surface of the valve element 5 along the direction of main body 1
Degree（The thickness of valve element 5 can be such as considered as）.
Specifically, delivery port 4 is arranged on the side wall of main body 1, its shape and number are simultaneously not intended to be limited in any.Preferably,
Delivery port 4 can be rectangle, and length direction is parallel with the length direction of runner 2.
In the present embodiment, electromagnet 6 and the "on" position of power supply 8, valve element 5 to second when valve element 5 is in first position
When position is moved, the distance of electromagnet 6 and valve element 5 increases, in the case where the electric current that power supply puts on electromagnet 6 is constant, electricity
The suction that magnet 5 is put on valve element 5 is less and less, so as to avoid the problem of water can not open the solenoid check valve or open
Degree is smaller and influences to carry out water-carrying capacity.Wherein, to cause the incipient suction force that electromagnet 6 applies to valve element 5 adjustable, the spacing ring 7
It is detachably connected with the inwall of runner 2.Specifically, the inwall of runner 2 is provided with internal thread, the spacing ring 7 is provided with
External screw thread, the spacing ring 7 is connected with the inner thread of runner 2.
Wherein, electromagnet 6 is fixedly installed on the inwall of runner 2, specifically, electromagnet 6 can be viscous by glue sealing
On the wall for being connected on runner 2.Electromagnet 6 passes through main body 1 by cable（There is seal approach between cable and main body 1）To connect electricity
Source 8.Power supply 8 can power to electromagnet 6.Can be provided with switch between power supply 8 and electromagnet 6（It is not shown）, so that control be
It is no to be powered to electromagnet 6, realize that the solenoid check valve carries out check function to water when needed whereby.Power supply 8 is provided to electricity
The electric current of magnet 6 is constant, so that the magnetic field of electromagnet 6 itself formation is constant.
As shown in figure 1, valve element 5 uses iron or ferroalloy for material, attracted with the electromagnet under being energized.Valve element is plectane
Shape.To prevent valve element 5 to be ejected outside runner 2, the one end of the runner 2 away from the water inlet 3 is provided with plugging plate 9；Institute
Plugging plate 9 is stated positioned at the delivery port 4 away from the side of valve element 5.
In the present embodiment, valve element 5 is in first position, is moved by the hydraulic pressure of the side of water inlet 3 to the second place
When, when the movement pre-determined distance of valve element 5 reaches the second place, water inlet 3 could be connected with delivery port 4.After hydraulic pressure venting, valve element
5 return to first position under the suction of electromagnet 6.When valve element 5 is in first position, electromagnet 6 may be at free state（Nothing
Stretching）, pretensioned state can also be in, so as to put on the pre- suction of valve element 5 one.
When there are water pressure fluctuations in runner 2, water pressure fluctuations are put on valve element 5, and valve element 5 is to the second place（Delivery port
4）Mobile, in the moving process of valve element 5, the solenoid check valve is in non-connected state all the time, because the pressure of water pressure fluctuations is tieed up
Hold that the time is short and pressure transient, therefore in water pressure fluctuations, valve element 5 by pre-determined distance movement the water pressure fluctuations are delayed
Wash out, be not in the situation for opening by mistake and opening.
By above description as can be seen that the solenoid check valve of present embodiment passes through the first position to valve element 5 and the
Two positions set a pre-determined distance, so that valve element 5 can be moved in pre-determined distance when occurring water pressure fluctuations in pipeline, enter
And by water pressure fluctuations venting before the second place is reached, therefore, the solenoid check valve that present embodiment is provided can be effectively
Avoid because pipeline hydraulic pressure fluctuate occur open by mistake the problem of opening.
Herein cited any digital value all include between lower limit to higher limit with the lower value of an incremented and
The all values of upper value, the interval that there are at least two units between any lower value and any much higher value.For example, such as
Fruit elaborates the quantity or process variable of part（Such as temperature, pressure, the time）Value be from 1 to 90, preferably from 20
