Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Example is applied to be described in further detail.
Fig. 2 is a kind of schematic diagram for the specific embodiment of solenoid valve that the present invention provides, and Fig. 3 is that solenoid valve connects in Fig. 2
The partial enlargement diagram of pipe and the fixed position of valve pocket, Fig. 4 are that valve pocket and the partial enlargement of the solder distribution after adapter tube welding show
It is intended to.
Shown in as shown in Figure 2, Figure 3 and Figure 4.In the specific embodiment provided, solenoid valve includes valve component 1 and coil group
Part 2.Valve component 1 includes valve pocket 21, and static iron core 22 is weldingly fixed on one end in valve pocket 21, and valve seat 24 is weldingly fixed on valve pocket 21
The interior other end, forms closed valve chamber 5 between valve seat 24 and static iron core 22, and dynamic iron core 23 is slidably disposed on valve chamber 5
In, the front end of dynamic iron core 23 is fixedly connected with spool 25.First adapter tube 3 is weldingly fixed on the side of valve pocket 21 and connects with valve chamber 5
Logical, the second adapter tube 4 is fixed on the end of the axial valve seat 24 of valve pocket 21, and the second adapter tube 4 is connected to the valve port 244 of valve seat 24.
Coil block 2 is fixed in the outside of valve pocket 21.
When coil block 2 is powered, under the action of electromagnetic field, static iron core 22 attracts dynamic iron core 23 upward with movable valve plug 25
Movement opens valve port 244, and such first adapter tube 3 and the second adapter tube 4 are connected；Equally when coil block 2 powers off, bullet is being replied
Under the action of spring 9, dynamic iron core 23 is moved downward with movable valve plug 25 abuts valve port 244, and such first adapter tube 3 and the second adapter tube 4 are disconnected
It opens.
In this specific embodiment, the side of valve pocket 21 offers the guide through hole 6 of inside necking, before the first adapter tube 3
End offers protrusion 7 by pier nose technique, and the front end of the first adapter tube 3 is inserted into the valve chamber 5 across guide through hole 6 and and valve
Set 21 is welded and fixed.
Valve seat 24 is in substantially step circles column structure, and centre opens up port as 244 hole of valve port.Valve seat 24 is from valve pocket 21
Lower part extend into valve chamber 5 and is welded and fixed with valve pocket 21, and the second adapter tube 4 is welded on the bottom of valve seat 24.
Valve seat 24 carries out axially position by the necking wall that the step surface 243 of stage portion 241 abuts guide through hole 6.First
The side 242 that the front end of adapter tube 3 abuts stage portion 241 carries out axially position.
In the welding position (see Fig. 4) of the first adapter tube 3 and valve pocket 21, welding region forms longer cooperation welding surface, increases
Add fusion length, while protrusion and throat structure, made to be formed between two soldering parts by complex-shaped gap not of uniform size,
Conducive to the infiltration of solder, weld strength is improved.On the other hand, guide through hole 6 is inside necking design, the step surface that outside is constituted
Again convenient for placing weld-ring when welding, welding procedure can be with simple operations.
The design scheme of the above structure the advantage is that increase fusion length, improve weld strength.Even if valve pocket and adapter tube
Using thin metallic tubd material, also not needing to increase other auxiliary pads, the weld strength being likely to occur is inadequate to be asked to make up
Topic, reduces components usage quantity, reduces assembling procedure number, simplify packaging technology.So being especially suitable for metal pipe material
Material welding, such as uses the welding of stainless steel pipe and copper pipe, is also able to satisfy the job requirement of solenoid valve.
It is determined by test, the distance between the protrusion 7 of the first adapter tube 3 and the outer end of guide through hole 6 H are in 0.5mm--2mm
Between, the reliability of the welding between casing and adapter tube can be significantly improved.Such as apart from too small, the off-capacity of welding material 8
Increase weld strength cannot；Such as apart from excessive, although increasing welding material, solder infiltration is influenced.
Fig. 5 is the partial enlargement diagram that the solenoid valve another kind adapter tube that the present invention provides is connected and fixed mode with valve pocket.
As shown in Figure 5.It is with aforementioned concrete scheme difference, the guide through hole 6 of valve pocket 21 includes and the sheet from valve pocket 21
The guide part 61 and the planar portions 62 extended from guide part 61 that body extends, the 6 abutment plane portion 62 of protrusion of 3 front end of the first adapter tube
Realize positioning.The technical solution can also play the purpose that simplified structure designs and improves soldering reliability, and details are not described herein.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
