Abstract
The invention belongs to boiler furnace blast cap technical field, fixed connection structure between specially a kind of blast cap and adapter, it is simple and convenient that it installs replacing, it includes blast cap and adapter, annular boss is installed in the adapter, it is characterised in that the blast cap lower end is provided with inverted L-shaped notch, the inverted L-shaped buckle coordinated with the inverted L-shaped notch is installed, the inverted L-shaped buckle inlay card realizes the connection of the blast cap and the adapter in the inverted L-shaped notch on the annular boss.
Description
Technical field
The invention belongs to boiler furnace blast cap technical field, knot is fixedly connected between specially a kind of blast cap and adapter
Structure.
Background technology
At present type of attachment is typically a weld through between boiler furnace blast cap and adapter.Fig. 1 is cap structure schematic diagram, Fig. 2
For joint pipe structure schematic diagram, Fig. 3 is blast cap and adapter connection diagram, and it is connected form using spot welding.Due to wind
Cap and adapter are all casting, therefore spot welding connection has two, first, the welding characteristic of casting is poor, welding requirements is high；Two
After being a weld through, when needing dismounting blast cap to be checked, it is necessary to which solder joint grinder buffing, which breaks, can just remove blast cap, and general
It is all alloy electrode to weld use, all to beat jarring blast cap using sledgehammer in practice it is difficult to polish, and shakes disconnected weldering with this
Point, but beaing for external force easily causes adapter that fracture damage occurs at knuckle.
The content of the invention
In order to solve the above problems, the invention provides the fixed connection structure between a kind of blast cap and adapter, and it is installed
Change simple and convenient.
Its technical scheme is such：A kind of fixed connection structure between blast cap and adapter, it includes blast cap and adapter,
Annular boss is installed in the adapter, it is characterised in that the blast cap lower end is provided with inverted L-shaped notch, on the annular boss
The inverted L-shaped buckle coordinated with the inverted L-shaped notch is installed, the inverted L-shaped buckle inlay card is in described in inverted L-shaped notch realization
Blast cap and the connection of the adapter.
It is further characterized by, and the lower ending opening size of the inverted L-shaped notch is more than the inverted L-shaped buckle upper surface chi
Very little, the inverted L-shaped buckle is interference fitted with the inverted L-shaped notch inwall；
The blast cap lower end is uniformly provided with multiple inverted L-shaped notches, and the multiple of cooperation are provided with the annular boss
The inverted L-shaped buckle, the inverted L-shaped buckle are arranged counterclockwise clockwise or in the same direction in the same direction.
After structure using the present invention, when installing blast cap, inverted L-shaped notch, which is aligned, to detain after inverted L-shaped buckle makes inverted L-shaped card
Tip in into inverted L-shaped notch, then rotate blast cap and complete connection, blast cap can is clamped securely to when boiler plant is run
In adapter, it will not fall off, it is necessary to when removing blast cap, also only need opposite direction rotation blast cap just can easily remove, installation is more
Change simple and convenient.

Embodiment
See Fig. 4, Fig. 5, shown in Fig. 6, the fixed connection structure between a kind of blast cap and adapter, it includes blast cap 1 and adapter
2, annular boss 3 is installed in adapter 2, the lower end of blast cap 1 is uniformly provided with two inverted L-shaped notches 4, two are provided with annular boss 3
The individual inverted L-shaped buckle 5 with the cooperation of inverted L-shaped notch 4, inverted L-shaped buckle 5 is clockwise in the same direction or arranges counterclockwise in the same direction, inverted L-shaped buckle
5 inlay cards realize the connection of blast cap 1 and adapter 2 in inverted L-shaped notch 4；The lower ending opening size of inverted L-shaped notch 4 is more than inverted L-shaped buckle
5 upper surface sizes, inverted L-shaped buckle 5 are interference fitted with the inwall of inverted L-shaped notch 4, it is ensured that and inlay card more facilitates Simultaneous Stabilization good,
It will not fall off.
