Abstract
The utility model discloses a kind of vacuum system, and this vacuum system comprises vacuum pump and is connected with this vacuum pump and realizes the storing gas that is communicated with, and this storing gas has suction port, and this suction port is connected with the air outlet of vacuum pump by tracheae, thus forms vacuum structure; Described storing gas is have the gas holder, gas receiver or the gas-storing bag that hold air cavity; In described storing gas, Decompression valves is installed, forms pressure release passage.Decompression valves in vacuum pump of the present utility model controls, gas in storing gas is by after the predetermined value that exceedes Decompression valves, gas can from going out in gas to release, enter vacuum pump again, and then the pressure ratio entering chamber is larger, form larger pressure reduction, form the air-flow of enough flows and flow velocity, guarantee coating quality.
Description
Technical field
The utility model relates to a kind of vacuum system, divides belong to vacuum pumping device technical field by International Patent Classification (IPC) (IPC).
Background technique
At present, existing vacuum system is extracted out by vacuum pump by the gas in sealed chamber, and entering in another chamber, pressure is smaller, pressure reduction is enough large, thus cause the flow between two chambers and flow velocity slow, the effect of machining requirement can not be reached.
Thus, the present inventor considers to improve existing vacuum pump body, and this case produces thus.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of vacuum system that the sealing of a kind of rational in infrastructure, convenient to use, product is neat, two ends limb error is less, manufacturing efficiency is higher and cost is low.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of vacuum system, this vacuum system comprises vacuum pump and is connected with this vacuum pump and realizes the storing gas that is communicated with, and this storing gas has suction port, and this suction port is connected with the air outlet of vacuum pump by tracheae, thus formation vacuum structure.
Further, described storing gas is have the gas holder, gas receiver or the gas-storing bag that hold air cavity.
Further, in described storing gas, Decompression valves is installed, forms pressure release passage.
Further, the bleeding point of described vacuum pump is communicated with pressure reduction casing.
Further, described pressure reduction case comprises two separate cavitys, and each cavity all with an aforementioned vacuum pump, the formation Vacuuming structure and this vacuum pump is connected with storing gas, and then realize the pressure differential structure of two cavitys, thus realize the directional flow of fluid or gas.
Compared with prior art, advantage of the present utility model:
Vacuum pump is connected with storing gas by the utility model, and controlled by the Decompression valves in vacuum pump, but the gas that pressure is extracted out by vacuum pump is stored in storing gas, and gas in storing gas is by after the predetermined value that exceedes Decompression valves, gas from going out in gas to release, then can enter vacuum pump, and then the pressure ratio entering chamber is larger, form larger pressure reduction, form the air-flow of enough flows and flow velocity, guarantee coating quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; .
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to shown in Fig. 1, a kind of vacuum system, itself and pressure reduction case with the use of, described pressure reduction case 1 comprises two separate cavitys 11, and each cavity 11 is all connected with the bleeding point of a vacuum pump 2, and the air outlet of this vacuum pump 2 is communicated with by the suction port of tracheae with storing gas 3, thus realize being communicated with of vacuum pump 2 and storing gas 3; All offer or be provided with the monomer of release gas or fog in each cavity 11 in pressure reduction case 1, this monomer can be the inlet hole be opened on pressure reduction chamber interior wall, also can be the device that can discharge gas or fog, as gas rod.Aforementioned vacuum pump 2 is connected with storing gas 3 formation Vacuuming structure, and then realizes the pressure differential structure of two cavitys 11, thus realizes the directional flow of fluid or gas.
Refer to shown in Fig. 1, aforementioned storing gas 3 holds the gas holder of air cavity, gas receiver or gas-storing bag for having, and the preferred version of storing gas 3 is gas holder, is provided with Decompression valves in described storing gas, forms pressure release passage.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
