As Figure 1-Figure 4, the utility model embodiment provides a kind of magnetic valve, including electromagnetic assembly 1 and valve element 2, electricity
Magnetic assembly 1 includes guide groove 11, and valve element 2 includes determining core 21, return unit 22, seal 23, dynamic core 24 and valve body 25, determines core 21 and fix
In on guide groove 11, between return unit 22 is located at dynamic core 24 and determine core 21, move core 24 and the activity of guide groove 11 cooperation and move core 24 with it is close
Sealing 23 is connected, and valve body 25 is connected with electromagnetic assembly 1, and valve body 25 includes water inlet end 251, water side 252 and sealing 253, enters
Water end (W.E.) 251 includes the first intake tunnel 2511 located at the middle part of sealing 253, the axis of the first intake tunnel 2511 and dynamic core 24
Diameter parallel set.
The magnetic valve that the utility model embodiment provides includes first located at the middle part of sealing 253 due to water inlet end 251
Intake tunnel 2511, the diameter parallel of the axis of the first intake tunnel 2511 and dynamic core 24 is set, when dynamic core 24 is by high hydraulic pressure
During impact, parallel to the axis of dynamic core 24, the Impact direction for moving core 24 is balanced for the action direction of high pressure so that dynamic core 24 can be
Off normal of the axis direction movement of dynamic core 24 without causing dynamic core 24, so that dynamic core 24 can move certainly on guide groove 11
Such as；Simultaneously because dynamic core 24 can dynamic core 24 axis direction motion freely, thus also ensure that dynamic core 24, seal 23 with
The sealing cooperation of valve body 25 is unaffected, so that magnetic valve has good sealing effectiveness, extends the use of magnetic valve
Life-span.
Further, the axis of the axis of the first intake tunnel 2511 and dynamic core 24 overlaps, when dynamic core 24 is by height
During hydraulic shock, this set can further make the Impact direction of core 24 balanced, avoid dynamic core 24 that off normal occurs, so that
Core 24 must be moved can move the sealing effectiveness for more freely, ensureing magnetic valve on guide groove 11.
Further, sealing 253 is provided with the step 2531 for being used for coordinating with seal 23 or dynamic core 24.Step 2531
It is engaged including the first step 2532 of first step 2532 with dynamic core 24, for making core 24 be fitted close with valve body 25.Can be with
Understand, dynamic core 24 is provided with lozenges 241, and lozenges 241 coordinates with first step 2532.Water side 252 and sealing 253
First step 2532 connect.The sealing 253 of the magnetic valve of above-described embodiment can be good fit with dynamic core 24, further protects
The sealing effectiveness of magnetic valve has been demonstrate,proved, has extended the service life of magnetic valve.
Further, step 2531 includes second step 2533, and second step 2533 coordinates with seal 23, close for making
Sealing 23 is hermetically pressed into valve body 25 and cuts off the flow of fluid between water inlet end 251 and water side 252.Further,
One step 2532 is located between the first intake tunnel 2511 and second step 2533.The sealing of the magnetic valve of above-described embodiment
253 can be good fit with seal 23, further ensures the sealing effectiveness of magnetic valve, and extend magnetic valve uses the longevity
Life.
Further, sealing 253 is provided with gas pressure relief slot 2534, connects for avoiding sealing 253 from coordinating with seal 23
Vacuum is formed when connecing.In closed electromagnetic valve, the sealing 253 of this structure is connected with seal 23 and will not formed very
Sky, thus when magnetic valve needs to open, with sealing 253 compared with seal 23 coordinates company to form vacuum state, for inciting somebody to action
The power that seal 23 is separated and acted on seal 23 with sealing 253 is obviously reduced, that is, is used for dynamic core 24 and sealing
253 power for separating and acting on dynamic core 24 are obviously reduced, thus reduce the energy loss of magnetic valve, improve magnetic valve
Operating efficiency.

Disconnected flow of fluid between water inlet end and water side.Thus, compared with a diameter of 4mm intake tunnel, the sealing of this structure
When part 23 seals intake tunnel, the sealing area sealed reduces four times, and because the elastic force of return unit 22 is certain, thus this is close
Sealing 23 and fix the pressure that the dynamic core 24 of the seal 23 is born and significantly increase, thus the first water inlet of the magnetic valve is logical
The small volume in road 2511 but dynamic core 24 can at elevated pressures normal work and realize being turned on and off for magnetic valve.
In the utility model embodiment, it is preferred that return unit 22 is spring, and return unit is arranged and moved the periphery of core 24.
Seal 23 is fixed on dynamic core 24.
The operation principle of the utility model embodiment：
When needing opens solenoid valve, electromagnetic assembly 1 is powered, core 24 is moved in guide groove 11 by caused electromagnetic force
On moved along close to the direction for determining core 21, for seal 23 to be lifted from valve body 25 and allows water inlet end 251 and water side 252
Between flow of fluid, in this process, return unit 22 is compressed.When needing to close magnetic valve, dynamic core 24 passes through reset
The elastic force of part 22 moves in guide groove interior edge away from the direction for determining core 21, for seal 23 to be hermetically pressed into valve body 25 and cut
Disconnected flow of fluid between water inlet end 251 and water side 252.
Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model scope claimed.
