Abstract
The utility model provides a be applied to automatically regulated gas flow's transmission control mechanism comprises needle valve, step motor, drive screw, shaft coupling. Characterized by step motor is through even boss and drive screw realization flow regulation rod's rotation to realize adjusting flow dimension's mesh. The utility model has the advantages that, structural design is simple, and it is convenient to maintain, control accuracy is higher etc..
Description
Technical field
This utility model belongs to automation field, specifically related to a kind of transmission control being applied to automatically adjust gas flow
Mechanism processed.
Background technology
The method being used for adjusting gas flow with scientific and technical development, traditional manual metering pin valve, has not met complete
The development of automatic detection instrument, and the mode precision adjusting manually is poor.Country is more and more heavier to air quality monitoring at present
Depending on, and the gas extraction amount of gas detecting front end requires the testing agency of energy stable supplying subordinate, this will affect the detection of this rear class
The stability of data, directly determines the integral level of whole detection instrument.
Content of the invention
The purpose of this utility model is to design a kind of transmission controlling mechanism being applied to automatically adjust gas flow, be used for
Automatically adjust the air inflow of needle-valve it is ensured that the steadily lasting testing agency of supply subordinate of air inflow, improve whole detection instrument
Stable type.
The technical solution of the utility model is that a kind of transmission controlling mechanism being applied to automatically adjust gas flow, by pin
Valve（1）, flow control rod（3）, fixed seat（2）, transmission screw（5）, shaft coupling（4）, motor（6）Composition, wherein needle-valve
（1）Flow-rate adjustment be by rotation flow adjusting rod（3）, realize screw telescopic thus reaching the regulation of flow, fixing in Fig. 1
Seat（2）One end pass through screw nut and needle-valve（1）Axle（8）It is fixed together, the other end is fixed by screw motor
Together.And shaft coupling（4）It is fixed by screws in the rotating shaft of motor（7）On, realize needle-valve flow control rod and stepping
Motor transmission shaft connects and concentric function, and four hole positions on shaft coupling (4) can fix four transmission screws（5）, four holes
Position is concentric with motor power transmission shaft, and each connection member can reduce system vibrations and the generation of harm moment of torsion with one heart, is driven screw
（5）Length have enough surplus capacities behind four holes on flow control rod, between transmission screw and flow control rod not
Fixing, and the part that transmission screw is contacted with flow control rod is smooth, non-threaded, motor drives four transmission screws
Rotating, driving flow control rod to rotate thus realizing the regulation of flow again.The length of transmission screw ensures to realize needle-valve complete
All the time it is in connection status with flow control rod when opening or closing.Transmission screw length be to ensure that needle-valve can fully open and
The key factor closed.
The utility model has the advantages that, manual modulation valve achieves, by simple frame for movement, the work(automatically adjusting
Can, contribute to the realization further of product automation, and precision is very high, the control of precision is determined by the rotational angle of motor
Fixed.It is applied to the control that all gas detect forward end gas amount.
Brief description
Fig. 1 is overall schematic of the present utility model.
Fig. 2 is drive mechanism schematic diagram of the present utility model.
In Fig. 1,1 needle-valve, 2 fixed seats, 3 flow control rods, 4 shaft couplings, 5 transmission screws, 6 stepping electricity
Machine, 7 motor power transmission shafts, 8 needle-valve fixing axles.
Specific embodiment
As shown in figure 1, needle-valve and motor are connected by fixed seat, spindle section is fixed on the transmission of motor
On axle, shaft coupling is fixed four transmission screws simultaneously, transmission screw passes through four holes of flow control rod of needle-valve, by driving
Flow control rod rotates, and realizes the purpose of flow automatic regulation.
