Hinge 6 is installed, the hinge 6 is hinged with cylinder 3 on valve plate of the present utility model 2, the other end of cylinder 3 and valve
Fixed hinge 7 on 8 is hinged.
Rotating shaft is inside hinge lower fixture in hinge of the present utility model 6.
Cooling water tube seat is provided with valve plate of the present utility model 2, the cooling water pipe 1 is arranged in cooling water tube seat,
Cooling water pipe 1 is around a circle valve plate 2.
Valve plate of the present utility model 2 is shaking hands to be provided with more than one observation window 4 on 5 sides.
Rubber seal is provided with valve plate of the present utility model 2.
The utility model outwards pulls open handle 5 manually when gate valve is opened in job requirement, and valve plate 2 is under the constraint of hinge 6
Stop after rotating up 90 ° along axle center, by 2 gas spring supportings above turnover valve port, substrate turnover vacuum chamber；Close gate valve
When, pulling handle 5 downwards manually, valve plate 2 is fitted on vacuum chamber wallboard after 90 ° are rotated down along axle center under the constraint of hinge 6,
Vacuum system starts to vacuumize.During working condition, cooling water pipe 1 has 16 DEG C~28 DEG C recirculated waters to flow all the time, takes away in time true
Heat of the empty room inside heat transfer to valve plate.Two observation windows 4 can be in Real Time Observation vacuum chamber working condition.
Its advantage is：
1. good seal performance, valve rubbers sealing ring and valve board installing structure are firm, sealing property when valve is switched repeatedly
Keep good, do not have leakage phenomenon.Sealing ring is standard rubbers O-ring, and sealing surface is higher by about after loading in valve plate dovetail groove
1.5mm, soft rubber ring is formed with port wall after valve closing compression and sealed.Sealing width of rebate is less than O-ring diameter,
Gate valve will not fall when opening repeatedly causes seal failure.When valve plate is closed, two gas springs have the pressure of about 0.2kPa to valve plate
Power, is brought into close contact valve plate and port wall, quick response vacuum system pumping work.
2. compact conformation, easy to maintenance, convenient processing and manufacture, low cost.Valve plate is narrow, small volume, action width during unlatching
Degree does not influence other processing steps of equipment, and open position facilitates workpiece into and out of vacuum chamber.The constraint of valve plate rotation closing page,
Rotating shaft is hardly damaged and falls inside hinge lower fixture in hinge 6, durable in use.
3. with spring cylinder, stop position is fixed after valve plate is opened, reliable, does not influence substrate discrepancy to act, without external
Source of the gas and other power.Valve plate is supported or suppressed by two spring cylinders.When valve plate is opened, this two spring cylinders are valve plate
Valve port top is supported on, this two spring cylinders give valve plate lasting press power when gate valve is closed.
4. high temperature resistant, internal vacuum chamber has elevated heating processes, and valve long-term use temperature is even more than 400 DEG C, if not having
There is cooling measure, seal meeting premature aging follows the string, so as to lose sealing property；The cooling water pipe of valve plate upper periphery insertion
1 can make valve plate keeping temperature no more than 50 DEG C, and the even common nitrile rubber material of sealing ring can meet this temperature will
Ask.Valve plate embedded groove coordinates the appearance and size of cooling tube 1, adds the technique of soldering valve plate is fitted with cooling tube 1 closely with riveting system, hot
Conductive performance is good.
5. fluoroscopic observation window function, two observation windows 4 on valve plate can the Real Time Observation when equipment is run to greatest extent
Vacuum indoor situations.
The utility model is gathered multi -function in integral whole, and import and export valve is preferably switched for vacuum equipment provides one.
It is mainly be applied to vacuum glass production.
