Abstract
The utility model discloses a highly reliable glass coating film buffer, including into piece room and surge chamber, advancing on piece room and the surge chamber all that the intercommunication has a plurality of vacuum pumps, I department of import of entering the piece room is equipped with flap valve I, be equipped with the spill cavity in surge chamber and the tip that advances piece room intercommunication, spill cavity downside is equipped with the import II that is used for the former piece of glass to pass through, install flap valve II in the spill cavity, flap valve II is gone up to have through the bolt fastening and is imported II sealed cushion II in the gas pressure action lower seal, and flap valve I is gone up has the sealed cushion I in gas pressure action lower seal import I through the bolt fastening. The utility model discloses be in the high vacuum state advancing the broken vacuous in -process surge chamber in piece room, II imports of the II pairs of spill cavities of sealed cushion under big gas pressure action on the flap valve II are laminated more and more tightlyer, have played fine sealed effect, can not destroy the high vacuum state in the surge chamber because of the trouble of flap valve II always.
Description
Technical field
The utility model is specifically related to a kind of highly reliable glass coating snubber assembly.
Background technology
Glass is in coating process, and original sheet glass can pass through successively into sheet room and surge chamber, and Jin Pianshi ingress is provided with the flap valve I of unlatching for controlling this porthole, position and closing seam, enters between sheet room and surge chamber and is provided with flap valve II.In the prior art, former of each sheet glass enters into before sheet room, enters sheet room and all will break a vacuum and allow air enter into sheet room, could open flap valve I allow original sheet glass enter into sheet room when indoor and outdoor pressure is equal.Now, whole enter the pressure of sheet chamber interior be a normal atmosphere, although the inlet face entering sheet room exit face and surge chamber is closed by flap valve II and seals, air can not enter surge chamber, if but there are some glitch in flap valve II, under the effect of air, this flap valve trim probably rushes down leakage, thus destroys the high vacuum state of surge chamber, and reliability is poor.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of highly reliable glass coating snubber assembly, to solve the poor problem of existing snubber assembly reliability.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of highly reliable glass coating snubber assembly, comprise into sheet room and surge chamber, enter on sheet room and surge chamber and be all communicated with multiple vacuum pump, import I place entering sheet room is provided with flap valve I; Surge chamber with enter in end that sheet room is communicated with to be provided with spill chamber, be provided with the import II passed through for original sheet glass on the downside of spill chamber; Flap valve II is installed in spill chamber, flap valve II is bolted the sealed bolster II in gas pressure lower seal import II, flap valve I is bolted the sealed bolster I in gas pressure lower seal import I.
the beneficial effects of the utility model are:
1, surge chamber of the present utility model with enter in end that sheet room is communicated with to be provided with spill chamber, be provided with the import II passed through for original sheet glass on the downside of spill chamber; Flap valve II is installed in spill chamber, flap valve II is bolted the sealed bolster II in gas pressure lower seal import II, flap valve I is bolted the sealed bolster I in gas pressure lower seal import I.In the process entering sheet room vacuum breaker, surge chamber is in high vacuum state always, import II place of the sealed bolster II pair of spill chamber under normal atmosphere effect on flap valve II fits more and more tighter, serve good sealing effectiveness, the high vacuum state that can not destroy in surge chamber because of the fault of flap valve II.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, flap valve I; 2, sheet room is entered; 3, flap valve II; 4, surge chamber; 5, original sheet glass; 6, spill chamber; 7, vacuum pump; 8, import I; 9, sealed bolster I; 10, import II; 11, sealed bolster II.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of highly reliable glass coating snubber assembly, comprises into sheet room 2 and surge chamber 4, enters on sheet room 2 and surge chamber 4 and is all communicated with multiple vacuum pump 7, and import I 8 place entering sheet room 2 is provided with flap valve I 1; Surge chamber 4 with enter in end that sheet room 2 is communicated with to be provided with spill chamber 6, be provided with the import II 10 passed through for original sheet glass 5 on the downside of spill chamber 6; Flap valve II 3 is installed in spill chamber 6, flap valve II 3 is bolted the sealed bolster II 11 in gas pressure lower seal import II 10, flap valve I 1 is bolted the sealed bolster I 9 in gas pressure lower seal import I 8.
In implementation process, entering into before sheet room 2 at original sheet glass 5, is be in high vacuum state in the chamber entering sheet room 2.When original sheet glass 5 needs to enter into sheet room 2, enter in sheet room 2 and just need enter air vacuum breaker, entering when in sheet room 2, pressure reaches a normal atmosphere to open flap valve I 1, original sheet glass 5 is entered into sheet room 2 by import I 1.
Be in high vacuum state in the chamber of surge chamber 4 always, when entering sheet room 2 vacuum breaker and opening in the whole process of flap valve I 1, import II place of the sealed bolster II pair of spill chamber 6 under normal atmosphere effect on flap valve II 3 fits more and more tighter, serves good sealing effectiveness.Enter completely at original sheet glass 5 and close into sheet room 2 end blocking valve I 1, start to vacuumize to entering sheet room 2 by vacuum pump 7, opening when entering sheet room 2 end blocking valve II 3 equal to the absolute pressure of surge chamber 4 inside, entering after surge chamber 4 until original sheet glass 5 and entering subsequent work program.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
