Background technique
Gas pipeline (gaspipeline) includes control valve, filter, decompressor, pressure gauge, flowmeter, online
Analyzer etc. is preferably concentrated and is located at gas access room.Gas is after the pressurization such as air blower, compressor, pump and boiler, from the height of pipeline
It is flowed at low pressure at pressure, the pressure or gravity conveying of gas itself can also be used.When known to the flow of gas, the size of caliber
Depending on the flow velocity of permission or the frictional resistance (pressure drop) of permission.Caliber is small when flow velocity is big, but pressure drop values increase.But pump and
The operation energy consumption expense of the power-equipments such as compressor increases.In addition, if flow velocity is excessive, it is also possible to which it is some other unfavorable to bring
Factor.Therefore caliber should consider to determine according to construction investment, operating cost and other technologies combined factors.Any mechanical equipment
In all flowed with air-flow from a side to the other side in pipe design, according to fluid mechanics principle airflow direction according to pipeline side
To flowing, Technology design requires air-flow uniformly to flow to side, and existing pipeline turns to and the bore reasons such as from large to small, makes
It smooth cannot be flowed to side at air-flow, cause the loss of air-flow.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of controllable pipeline airflow direction and positioning device,
It can solve existing pipeline to turn to and the bore reasons such as from large to small, cause air-flow smooth cannot flow to side, cause gas
The problem of loss of stream.
In order to solve the above technical problems, the utility model provides the following technical solutions:
A kind of controllable pipeline airflow direction and positioning device, including air duct are pacified at the position of the steering outlet in the air duct
Equipped with butterfly valve, the butterfly valve includes the first flap and the second flap, first flap and the second flap with butterfly valve axis connection,
One end transmission connection transmission device of the butterfly valve axis, the air duct inside are equipped with annulus, are equipped on second flap
Cylinder, the cylinder and annulus are slidably connected.
As a kind of optimal technical scheme of the utility model, first flap is fixed flap, second flap
For movable flap.
As a kind of optimal technical scheme of the utility model, driving motor is installed, and drive in the transmission device
Motor passes through belt transmission connection butterfly valve axis.
As a kind of optimal technical scheme of the utility model, the material of the butterfly valve is stainless steel.
As a kind of optimal technical scheme of the utility model, the transmission device connects external power supply.
Compared with prior art, the attainable beneficial effect of the utility model is: the utility model turns in air duct
Exit be arranged a butterfly valve, when butterfly valve in vertical state when, outlet closing, when rotation (clockwise or counterclockwise)
When certain angle, air-flow will can be blocked along the smooth flow direction that is open, rest channels by butterfly valve, and rotational angle size is by butterfly valve
Axis determines that the loss of air-flow is walked about and greatly reduced to the air-flow that can be used for different pipelines with butterfly valve link position.

Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
It please refers to shown in Fig. 1-4, a kind of controllable pipeline airflow direction and positioning device, including air duct 1, the air duct 1
It turns to and butterfly valve 9 is installed at the position of outlet 7, the butterfly valve 9 includes the first flap 3 and the second flap 5, first flap 3
It connect with butterfly valve axis 2 with the second flap 5, one end transmission connection transmission device 4 of the butterfly valve axis 2, pacifies on the inside of the air duct 1
Equipped with annulus 6, cylinder 8 is installed on second flap 5, the cylinder 8 and annulus 6 are slidably connected.
First flap 3 is fixed flap, and second flap 5 is movable flap, convenient for being adjusted according to demand,
For the angle between regulating butterfly valve 9, driving motor is installed, and driving motor is driven by belt in the transmission device 4
Butterfly valve axis 2 is connected, convenient for more preferably driving to flap, adjusts angle.The material of the butterfly valve 9 is stainless steel, reduces corrosion,
The transmission device 4 connects external power supply.
Specifically, when in use, turned in air duct 1 and a butterfly valve 9 be set at outlet 7, when butterfly valve 9 in vertical state
