To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of bellows device of air-blast quenching experiment, including end plate, cabinet, blast connection, movable plate, nozzle angle are adjusted
Device, tank ends are fixedly connected with end plate, and blast connection is connected on cabinet side plate, and another side plate of cabinet is equipped with opening, opens
Mouth periphery is equipped with seal groove, sealing strip is equipped in seal groove, movable plate is connect by bolt with the box side equipped with opening, living
Multiple Nozzle angle adjustment devices for being used to connect nozzle are arranged on movable plate, Nozzle angle adjustment device includes transit joint, ball
Seat, globe joint and transition block, the bulb of globe joint are placed in ball seat inner cavity, and globe joint top with ball seat screw thread by connecting
The transit joint locking connect, transit joint lower part connect excessive block, and transit joint, globe joint, excessive block centre are equipped with ventilation
Chamber.
The sealing strip is O-type seal.
The Nozzle angle adjustment device is threadedly coupled with movable plate.
The venting cavity of the transit joint, globe joint is circular hole, and the venthole of transit joint lower part compares globe joint
The big 5-15mm of ventilation bore dia.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, strong operability, and cabinet connects to form whole bellows with movable plate, in wind box and
The airtightness that sealing strip is used to ensure bellows is installed at the joint face of movable plate.
The flexibility of test is improved by increasing replaceable movable plate, for needing in the experiment of metal material air-blast quenching
Different air outlet types, different air outlet spacing, different air outlet quantity difference operating conditions are tested respectively, it is only necessary to which replacement is corresponding
Movable plate.Nozzle angle adjustment device is installed on movable plate, changes flow angle by changing nozzle angle.It can be big
Amplitude improves Efficiency and reduces research cost.
