Joint pipe structure, the inserted terminal (left end in Fig. 4-7) of take over 3 all has the bending part of inside bending, bending in above example
Portion forms grafting end face 31.Certainly, without bending, but the take over 3 of straight pipe type can also be formed as described above in end face
Confined planes, but when setting bending part, under the premise of forming required confined planes, the thickness of take over 3 is without increasing.In inserted terminal
Integrally formed bending part, to be integrally formed above-mentioned required various confined planes, structure is more reliable.Certainly, by bending part
The take over 3 of structure welding to straight pipe type is also feasible.
In addition, in first to fourth embodiment, 3 inserted terminal top of take over is not contradicted with step surface 11, and being formed has axis
To the opening of size c, be conducive to the air that accommodating cavity internal residual is discharged after solder 2 melts, it is easier to take over 3 and valve seat 1
Between gap in flow.
In above example, be by the deformation design of take over grafting end face, to cooperatively form accommodating cavity with valve seat jack,
To achieve the effect that certain fixation solder, grafting end face are clearly not limited to above-mentioned design, for example, grafting end face can also be arc
Face.
In the utility model, setting accommodating cavity can limit solder, from valve seat and taking over it after preventing solder from softening
Between fall, also avoid solder and fall to fall behind in take in channel formation filiform, caused by solder hanging wire phenomenon, to ensure
The circulation in channel is taken over, while also just solving after filiform breaks to form impurity and solder fusing and flowing into nozzle interior
Problem.
The utility model also provides a kind of control valve, including valve casing 4, assembled with valve casing 4 after form the valve seat 1 of valve chamber, set
The take over 3 for setting the spool 5 in valve chamber and being welded on valve seat 1 and being connected to valve chamber, valve seat 1 are welded to connect knot with take over 3
Structure is above-mentioned connection structure.
Since above-mentioned valve seat has above-mentioned technique effect with the welding connection structure taken over, so including the control of the structure
Valve also has corresponding technique effect, and details are not described herein again.
Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as the scope of protection of the utility model.
