Abstract
The invention discloses a kind of plated film vacuum suction control systems, including ontology, ontology cover board, aspiration pump and stem tracheae and tail portion tracheae, the aspiration pump is connect with stem tracheae, when the ontology cover plate lid on the body when, two exhaust tubes form air-tightness connection in the joint；The present invention can save the plenty of time for carrying out the dismounting work of two exhaust tubes, to substantially increase production efficiency.
Description
Technical field
The present invention relates to extract systems, especially belong to vacuum-pumping system.
Background technique
At present in vacuum lines, a production line generally requires tens even up to a hundred mutually independent vacuum chambers
Room, the indoor gas of vacuum chamber enters the branch pipe of two sides through aspiration pump extraction, then is converged by two side branch into supervisor, by prime
Aspiration pump discharge is related to branch pipe and be responsible for the problem of connecting that aspiration pump connects in this way, is often responsible for position in the prior art
In the upper cover for being higher than vacuum chamber, aspiration pump connecting branch is attached with supervisor by metal hose, on the one hand each in this way
Vacuum chamber requires the branch pipe for connecting aspiration pump when needing to open or covering upper cover and the metal hose of supervisor carries out hand
Work disassembly needs to spend in this way since a production line generally requires tens even up to a hundred mutually independent vacuum chambers
The a large amount of time carries out the dismounting work of the branch pipe of aspiration pump connection and the metal hose of supervisor, to leverage production
Efficiency, and a large amount of energy is wasted, not only production cost is caused to greatly improve, nor is conducive to environmental protection；Another party
Face, the branch pipe and the interior vacuum degree of supervisor's pipe of aspiration pump connection are higher, the setting of the prior art higher to the seal request of junction
Often lead to junction gas leakage.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, installation side with deficiency in order to overcome the drawbacks of the prior art
Just, air-tightness is good, is not easy the plated film vacuum suction control system of gas leakage.
The purpose of the present invention can be by taking following technical scheme to reach:
A kind of plated film vacuum suction control system, including ontology, ontology cover board, aspiration pump, stem tracheae and tail portion tracheae composition,
The aspiration pump is fixed on ontology cover board, and the aspiration pump is connect with stem tracheae one end, stem tracheae and tail portion tracheae
One end all has a stem gas-tpe fitting and tail portion gas-tpe fitting being parallel to the horizontal plane, on stem gas-tpe fitting horizontal plane and ontology
Flush or be lower than body upper surface, when the ontology cover plate lid on the body when, the stem tracheae and tail portion gas
Pipe forms air-tightness at the stem gas-tpe fitting with tail portion gas-tpe fitting and connects.
As the preferred embodiment of the invention patent, the tail portion tracheae is connected by metal hose and stem gas-tpe fitting
It connects, the stem gas-tpe fitting along the circumferential direction has annulus type groove, and airtight packing, the tail portion are placed in annulus type groove
Tracheae is connect by metal hose with tail portion gas-tpe fitting, when the ontology cover plate lid on the body when, stem gas-tpe fitting
Air-tightness is formed with tail portion gas-tpe fitting to connect.And stem gas-tpe fitting and tail portion gas-tpe fitting faying face and ontology and ontology
Cover board faying face is concordant.
Compared with prior art, the invention has the following advantages that
One, it using the invention patent plated film vacuum suction control system, does not need manually to dismount tail portion when dismounting ontology cover board
The attachment device of tracheae and stem tracheae, since a production line generally requires tens even up to a hundred mutually independent vacuum
Chamber can save the plenty of time of the dismounting work for carrying out stem tracheae and tail portion tracheae, to greatly improve in this way
Production efficiency.
Two, since the invention patent pump plated film vacuum suction control system connects the stem tracheae connecting with tail portion tracheae
Head is horizontal, when the ontology cover plate lid on the body when, stem gas-tpe fitting forms air-tightness connection by the effect of gravity,
And during vacuumizing, since tail portion tracheae and stem tracheae all have certain vacuum degree, such stem tracheae is connect
The sealing that head and tail portion gas-tpe fitting leans on atmospheric pressure self-assembling formation more to fasten.
Detailed description of the invention
Fig. 1 is the overall structure figure of plated film vacuum suction control system of the present invention.
Specific embodiment
A specific embodiment of the invention is described in detail below in conjunction with attached drawing.
As shown in Figure 1, plated film vacuum suction control system of the present invention includes ontology 2, ontology cover board 1, aspiration pump 3, stem
Tracheae 4 and tail portion tracheae 5 form, and tail portion tracheae 5 is lower than ontology cover board 1, and tail portion tracheae 5 passes through metal hose 6 and stem tracheae
Connector 7 connects, and stem gas-tpe fitting 7 along the circumferential direction has annulus type groove, airtight packing, the head are placed in annulus type groove
Portion's tracheae 4 is connect by metal hose 8 with tail portion gas-tpe fitting 9, when the ontology cover plate lid 1 is covered on ontology 2, due to
Tail portion gas-tpe fitting 9 and 7 faying face of stem gas-tpe fitting it is parallel with ontology and body cap plate faying face i.e. be parallel to the horizontal plane,
Tail portion gas-tpe fitting 7 relies on the gravity pressure of stem tracheae 4 and ontology cover board 1 on stem gas-tpe fitting 7, meanwhile, stem tracheae
Connector 7 along the circumferential direction has annulus type groove, and airtight packing is placed in annulus type groove, therefore, stem gas-tpe fitting 7 and tail portion
Gas-tpe fitting 9, which does not need any mechanical connection, can form air-tightness connection, so that lifting ontology cover board is very convenient, this
Sample generally requires tens even up to a hundred mutually independent vacuum chambers for a production line, can save for carrying out
Tail portion tracheae 5 and stem tracheae 4 dismount the plenty of time of work, to substantially increase production efficiency, and also save big
The energy of amount, not only substantially reduces production cost, but also is also beneficial to environmental protection.
Meanwhile during evacuation, stem tracheae 4 and tail portion tracheae 5 have certain vacuum degree, stem gas-tpe fitting
7 and the contact surface of tail portion gas-tpe fitting 9 the more can inhale the more tight by the pressure of atmosphere, gas leakage will not be led to the problem of, in this way, well
Solves the problems, such as the easy gas leakage of currently available technology.
Above disclosed is only presently preferred embodiments of the present invention, cannot limit the right of the present invention with this certainly
Therefore range according to equivalent variations made by scope of the present invention patent, is still within the scope of the present invention.
