Specific embodiment
Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.
As shown in Figures 1 to 6, the utility model provides a kind of liquid level sensor big flow solenoid valve, including valve body
1, fixed valve plug 2, movable valve plug 3, coil 4, elastic component 5, nipple 6 and coil brace 7.
There are two support portion 71 spaced apart, 2 both ends of fixed valve plug are each passed through two support portions 71 and determine valve the tool of coil brace 7
One end of core 2 is equipped with external screw thread, and a nut 81 for being located at 71 outside of support portion is tightened against this one end of fixed valve plug 2 to determine valve
Core 2 is fixed on coil brace 7, and gasket 82 is equipped between nut 81 and support portion 71.Coil 4 is wound around on fixed valve plug 2 and position
Between two support portions 71.
Nipple 6 is the other end that the not set screw thread of fixed valve plug 2 is fixed in hollow structure and one end, nipple 6 with
The fixed form of fixed valve plug 2 can be to be welded and fixed.The other end setting external screw thread of nipple 6 is simultaneously threadedly coupled, spiral shell with valve body 1
Sealing ring 9 is equipped between line connector 6 and valve body 1 to guarantee the leakproofness at the two link position.Movable valve plug 3 is located at nipple
In 6 and can opposite thread connector 6 slide axially and close to or far from fixed valve plug 2.5 sets of elastic component on movable valve plug 3 and elastic
It is resisted against between movable valve plug 3 and nipple 6, the elastic force that elastic component 5 provides pushes movable valve plug 3 far from fixed valve plug 2.
The inside of valve body 1 has cavity 10, and 1 one end of valve body is connect with nipple 6, and the other end offers water inlet 11,
The water outlet 12 between 1 both ends of valve body is offered on the side wall of valve body 1, water outlet 12 and water inlet 11 are not in same
It is different from the arrangement of intake-outlet in existing solenoid valve on one straight line.Valve body 1 has the slow splenium being convex in cavity 10
13, slow splenium 13 is L shape and one end is fixed on the side wall other end extension of valve body 1 and is convex to movable valve plug 3.Slow splenium 13 has direction
The slow pressure surface 14 of water inlet 11 can't will be into a certain distance from slow 14 size of pressure surface is less than water inlet 11 and has from water inlet 11
It is shut inside the mouth of a river 11, but the pressure of the fluid entered from water inlet 11 can be alleviated.Be equipped in slow splenium 13 entrance deviate from into
The intake tunnel 15 at the mouth of a river 11 and one end are connected to the exhalant canal 16 that the other end is connected to water outlet 12 with intake tunnel 15, into
Aquaporin 15 and exhalant canal 16 are mutually perpendicular to and are connected as L shape.Intake tunnel 15 and the diameter of exhalant canal 16 can be
8.1mm, but not limited to this.
The end face of movable valve plug 3 is resisted against on slow splenium 13 and entering intake tunnel 15 under the elastic force pushing tow of elastic component 5
Mouth is shut.To guarantee that sealing effect is good, movable valve plug 3 and slow splenium 13 contradict the face area at end greater than slow 13 corresponding end of splenium
The area in face is also still able to maintain to intake tunnel even if slight shift occurs radially in the relatively slow splenium 13 of movable valve plug 3
The closing of 15 entrances.Movable valve plug 3 is attracted by magnetic force close to fixed valve plug 2 after coil 4 is powered, and movable valve plug 3 overcomes during being somebody's turn to do
The elastic force of elastic component 5 compresses elastic component 5, and leaving on splenium 13 of then postponing makes the entrance of intake tunnel 15 be opened.
It is as shown in phantom in Figure 6 the flow direction of liquid in this solenoid valve, the fluid entered from water inlet 11 meets with slow first
The blocking of pressure surface 14 and deflecting is flowed backward, after fluid reaches slow splenium 13 again deflecting from the entrance of intake tunnel 15 into
Enter and pass through the water outlet 12 that exhalant canal 16 flows to valve body.
Compared with prior art, valve is convex to due to being provided in the liquid level sensor big flow solenoid valve of the utility model
Slow splenium 13 inside body 1, which has the slow pressure surface 14 towards 1 water inlet 11 of valve body, and is connected to the water outlet of valve body 1
The entrance of the intake tunnel 15 of mouth 12 then deviates from water inlet 11, therefore can meet with slow pressure surface first from the fluid that water inlet 11 enters
Then 14 blocking is just flowed out from water outlet 12 after deflecting several times.It can be significant by the way that slow splenium 13 is arranged in this solenoid valve
Fluid pressure and resistance are reduced, the steady opening for controlling movable valve plug 3 or sealing are conducive to.It is to pass through end additionally, due to movable valve plug 3
Face is supported to close 15 entrance of intake tunnel, also close there is no need to overcome there is no need to be arranged sealing ring in the periphery of movable valve plug 3
Seal and 1 frictional force actuation of valve body, are more advantageous to the smooth sliding of spool.
Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art
Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application
Equivalent variations made by sharp range still falls within the range that the utility model is covered.
