Abstract
The utility model belongs to technical field of mechanical processing, and in particular to the sealing ring O-ring of original butterfly valve outer ring is removed, add pneumatic operated valve, sets the opening and closing of pneumatic operated valve according to demand by a kind of butterfly valve for promoting LED luminance.The effect of butterfly valve is control angle of release size, stablizes cavity internal pressure, the effect of steady air flow.The utility model has the beneficial effects that after O-ring is removed in transformation, butterfly valve does not rub with edge, concussion is reduced, butterfly valve is more steady when angle of release changes, so that the speed of exhaust is more smooth, stablize the pressure in entire growth course, butterfly valve angle of release shock range is smaller especially at MQW, so that pressure is more stable, MQW air-flow is more uniform, thermal field can also be well controlled, and the more optimization of V/III proportion realizes a kind of LED growing method of more Seedling height efficiency so that the brightness of entire epitaxial wafer is effectively promoted.
Description
Technical field
The utility model belongs to technical field of mechanical processing, and in particular to a kind of butterfly valve for promoting LED luminance.
Background technique
Aixtron CRIUS series board is often led in LED growth course because O-ring turns up because of butterfly valve problem
It causes the pressure difference of the pressure and the rear end PT in cavity big and leads to chaser.There are O-ring for traditional butterfly valve, in angle of release variation
Butterfly valve and O-ring rub, and the angle of release of butterfly valve is caused to shake, and in turn result in that air-flow is unstable, influence the electrical property of entire LED and bright
Degree.
Utility model content
In view of the above problems, the utility model provides a kind of butterfly valve for promoting LED luminance.
The technical solution of the utility model includes:
A kind of butterfly valve promoting LED luminance, the sealing ring O-ring of original butterfly valve outer ring is removed, pneumatic operated valve, root are added
According to the opening and closing of demand setting pneumatic operated valve.
The effect of butterfly valve is control angle of release size, stablizes cavity internal pressure, the effect of steady air flow.
The utility model has the beneficial effects that butterfly valve does not rub with edge after O-ring is removed in transformation, concussion is reduced, butterfly
Valve is more steady when angle of release changes, so that the speed of exhaust is more smooth, stablizes the pressure in entire growth course, especially exists
Butterfly valve angle of release shock range is smaller at MQW, so that pressure is more stable, MQW air-flow is more uniform, and thermal field can also obtain well
Control, the more optimization of V/III proportion realize a kind of more Seedling height effect so that the brightness of entire epitaxial wafer is effectively promoted
The LED growing method of rate.
Detailed description of the invention
Fig. 1 is the butterfly valve schematic diagram for having O-ring.
Fig. 2 is the schematic diagram of butterfly valve after removing O-ring.
Fig. 3 is the angle of release figure for having the butterfly valve of O-ring at Quantum Well.
Fig. 4 is the angle of release figure for removing the butterfly valve of O-ring at Quantum Well.
In figure: 1 rotary shaft；2 butterfly valves；3 sealing ring O-ring.
Specific embodiment
Below in conjunction with attached drawing and technical solution, a specific embodiment of the invention is further illustrated.
Embodiment
As shown in Figure 2: the sealing ring O-ring of original butterfly valve outer ring is removed, is added by a kind of butterfly valve for promoting LED luminance
Pneumatic operated valve sets the opening and closing of pneumatic operated valve according to demand.
The effect of butterfly valve is control angle of release size, stablizes cavity internal pressure, the effect of steady air flow.
Claims (1)
