Abstract
The utility model discloses a low pressure helical -lobe compressor exhaust apparatus, including gas vent structure body, the higher authority of gas vent structure body sets up the gas vent, edge one side of the gas vent of gas vent structure body sets up the inclined plane to constitute the air guide step. As the utility model discloses further scheme: the exhaust port at low pressure helical -lobe compressor is fixed with gas vent structure body during the use to the inside passageway of gas vent intercommunication compressor cavity for the gas outlet and the compressor cavity exhaust port sealing connection of gas vent structure body. Exhaust port and air guide step have corresponding relation. The utility model discloses when low pressure helical -lobe compressor's rotor pressed scaling to reach the low pressure value, the air guide platform played the usage of air guide, can not produce the pressure of ordinary machine again, reduces organism internal pressure. This practicality is applicable to low press below the 0.5Mpa, optimizes its air guide performance, guarantees that certain compressor keeps lower input specific power, energy -saving power more in than.
Description
Technical field
This utility model is related to a kind of exhaust outlet structure, specifically a kind of low pressure screw compressor air exhausting unit.
Background technology
At home many users use compressed air in below 0.5Mpa, but using traditional air compressor machine minimum pressure
For 0.7Mpa, often user needs to install air relief valve that the compressed air of 0.8Mpa or 0.7Mpa is depressurized to into 0.5Mpa is used below
Compressor pressure often improves 0.1Mpa, and output at least increases by more than 6% energy consumption；Bring decompression is carried out plus air relief valve
Consume and cause because pressure ratio is higher screw rotor internal leakage increase, overall energy consumption is at least over more than 15%.Indivedual machines
Type energy consumption is even up to 15%-30%.
Utility model content
The purpose of this utility model is to provide a kind of low pressure screw compressor air-discharging mouth structure, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, this utility model provides following technical scheme：
A kind of low pressure screw compressor air exhausting unit, including exhaust outlet structure body, set above exhaust outlet structure body
Air vent is put, the edge side of the air vent of the exhaust outlet structure body arranges inclined plane, to constitute inducing QI step.
As further program of the utility model：Passage inside air vent connection compressor cavity, will row when using
Port configurations body is fixed on the exhaust port of low pressure screw compressor so that the gas outlet of exhaust outlet structure body and compressor
Cavity exhaust port is tightly connected.
As further program of the utility model：The surface of the inclined plane is provided with dentation mechanism.
As this utility model further scheme：Exhaust port and inducing QI step have corresponding relation.
Compared with prior art, the beneficial effects of the utility model are：Reach in the rotor compression ratio of low pressure screw compressor
During to low voltage value, inducing QI platform plays the purposes of inducing QI, will not again produce the pressure of common machine, reduces internal body pressure.This reality
With suitable for below 0.5Mpa low-pressure machines, optimize its inducing QI performance, it is ensured that certain compressor keeps relatively low input ratio than interior
Power, more energy saving.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1～4 are referred to, in this utility model embodiment, a kind of low pressure screw compressor air exhausting unit, including air vent
Structural body 1, arranges air vent 2 above exhaust outlet structure body 1, the passage inside the connection compressor cavity of air vent 2 makes
Exhaust outlet structure body 1 is fixed on the exhaust port 3 of low pressure screw compressor used time so that exhaust outlet structure body 1 goes out
QI KOU is tightly connected with compressor cavity exhaust port, discharges in advance in order to gas, and then realizes that gas constant-pressure mute is discharged.
The edge side of the air vent 2 of the exhaust outlet structure body 1 arranges inclined plane, to constitute inducing QI step 4, inclines
The surface in face is provided with dentation mechanism.
When the rotor compression ratio of low pressure screw compressor reaches low voltage value, inducing QI platform 4 plays the purposes of inducing QI, Bu Huizai
The pressure of common machine is produced, internal body pressure is reduced.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type is by claims rather than described above is limited, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as restriction
Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of description is only that for clarity those skilled in the art should
Using description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, form those skilled in the art
Understandable other embodiment.
