Description
Technical field
The present invention relates to a kind of magnetic valve.
Background technology
Magnetic valve includes conduit, static iron core and dynamic iron core, and installation opening, static iron core and dynamic iron are provided with conduit
Core is respectively assembled in conduit, wherein, static iron core is connected as a single entity with conduit by way of riveting.Work as electromagnetism
During the valve course of work, dynamic iron core constantly clashes into static iron core, and promotes static iron core to be moved to the end wall direction of conduit.
In 200,000 experiments of operating life of magnetic valve, dynamic iron core drives static iron core to clash into the end wall of conduit, this meeting
Cause sleeve pipe end wall to rupture, especially easily occur at the round-corner transition between duct wall and conduit end wall
Rupture.Thus, existing magnetic valve service life is low.
The content of the invention

The service life of valve, is thus not difficult to draw, improves the low cost spent needed for magnetic valve manufacturing process.When
When gap is less than 0.5mm, because magnetic valve has accuracy of manufacture error and assembly precision error, thus, buffering
Structure is difficult to play cushioning effect；When gap is more than 10mm, need to make suitable with the part of tubes fit
The size regulation of answering property, this can cause the rise of magnetic valve manufacturing cost.
Further, the buffer structure also includes bolster, and the bolster is fixedly attached to the quiet iron
On core and/or the conduit end wall.Bolster is used to strengthen the buffering effect of buffer structure.
Further, the static iron core is provided with locating slot, in locating slot described in the bolster partial insertion.
It is so designed that, bolster convenient disassembly.
Further, the bolster is at least one of bellows, spring and elastomeric pad.
Further, one of static iron core side wall and the duct wall are provided with positioning bar, another
Individual to be provided with locating slot, the positioning bar inserts the locating slot, so that the static iron core is fixed on the conduit
On.It is so designed that, static iron core convenient disassembly.
Further, the positioning bar is welded to connect with the locating slot.Be so designed that, increase static iron core with
Bonding strength between conduit, further to increase the service life of magnetic valve.
Further, the static iron core upper end is provided with chamfering.It is so designed that, between conduit end wall and its side wall
Round-corner transition at spacing distance and static iron core between become big, further to increase the service life of magnetic valve.
Further, the valve seat includes body and lid, and duct wall lower end outward bending is formed and turned over
Side, the flange is clamped between the body and the lid.It is so designed that, conduit convenient disassembly.
Further, the magnetic valve also includes buffering ring, and the lid compresses the buffering ring and led in described
The bending place of tube side wall.It is so designed that, the extruding force that duct wall bending part is subject to diminishes, further to increase
Plus the service life of conduit.
