Specific embodiment
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in combination with Examples.It should be noted that not conflicting
In the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.
In conjunction with referring to shown in Fig. 1 to Fig. 3, according to an embodiment of the invention, laminar flow device includes mounting circular ring 1 and fixed setting
Rectifier 2 at the channel of mounting circular ring 1, rectifier 2 include that the rectification of multiple axial directions extensions along mounting circular ring 1 is logical
Road 3.
When using the laminar flow device, which can be mounted on gas source outlet conduit by mounting circular ring 1, work as gas
Body can pass through rectifier 2, then flow along the rectification direction of rectifier, lead by the rectification of rectifier 2 after gas source outflow
To later, the disorder air-flow of gas source output also will become the regular flow along the flowing of rectification direction, therefore can be improved air-flow
The stability of flowing reduces the loss in air-flow flow process, reduces air-flow crushing.
For the ease of mounting circular ring 1 and gas source outlet conduit to be attached, can be set in the connecting pin of mounting circular ring 1
Threaded connection slot is set, connection screw thread is set on gas source outlet conduit, or outer spiral shell is arranged in the connecting pin of mounting circular ring 1
Internal screw thread is arranged on gas source outlet conduit in line, so that being connected between mounting circular ring 1 and gas source export pipeline by screw thread
It connects.Screw connection structure is not only simple in structure, easy to connect reliable, and can have preferable sealing performance.
Mounting circular ring 1 is made of rigid material, such as metal, engineering plastics, wood etc., can prevent from working in laminar flow device
During, due to being caused mounting circular ring 1 to deform by airflow acting force, influence asking for the rectification effect of laminar flow device
Topic.
Preferably, rectifier 2 is removably disposed on mounting circular ring 1.During using laminar flow device, if encountered
The case where needing replacing rectifier structure, without replacing entire laminar flow device, it is only necessary to by rectifier 2 from mounting circular ring 1
It disassembles, the rectifier 2 of type needed for then replacing, mounting circular ring 1 still may remain in installed position, therefore
A large amount of processes can be saved, the cost of replacement rectifier structure is reduced, improve replacement efficiency.
In order to guarantee there is stable connection structure between mounting circular ring 1 and rectifier 2, laminar flow device further includes locking piece 4,
Rectifier 2 is fixedly connected on the internal perisporium of mounting circular ring 1 by locking piece 4.Locking piece 4 can be fixed at mounting circular ring 1
On, then rectifier 2 is fixed on locking piece 4, to realize the fixed installation to rectifier 2.
Locking piece 4 is, for example, screw thread, and screw thread is fixed on mounting circular ring 1, and 2 padlock of rectifier is in screw thread.Pacifying
It is provided with card slot 5 on dress annulus 1, screw thread is fixed in card slot 5, and then 2 padlock of rectifier is in screw thread, so that fixation is set
It sets on mounting circular ring 1.Screw thread structure is simple, easy to operate, and connection positioning is reliable, can steadily fix rectifier 2 and set
It sets on mounting circular ring 1.
In the present embodiment, multiple screw threads are arranged along the circumferential uniform intervals of mounting circular ring 1, can be the peace of rectifier 2
Dress provides more uniform reliable padlock active force, guarantees that rectifier 2 is mounted on mounting circular ring 1 stress balance later, so that
Laminar flow device has better working performance.
