Description
Technical field
The utility model relates to accurate opertaing device technical field, relates in particular to a kind of shutoff type gas flow control device.
Background technology
In Fig. 1, this device comprises flow detection and control module 9, flowrate control valve 10, air flue 7; Described flow detection is connected with air flue 7 with control module 9, detects present flow rate, and contrasts with setting flow; Described flowrate control valve 10 is connected with air flue 7, in flow detection and control module 9, makes after calculating, by it, is controlled flow is adjusted; Described flowrate control valve 10 inside, by the coil winding post that dams, form electromagnet, under the effect of controlling electric current, produce magnetic field, by producing different adhesive degree with magnet, control air-flow; This device is expensive, and technique is loaded down with trivial details, and iff simple flow controller of needs, cost is too high, is unsuitable for producing.
Utility model content
The utility model object is that a kind of shutoff type gas flow control device is provided in order to overcome the deficiencies in the prior art, can require undemanding occasion in impermeability, reduces cost of products, simplified processing process.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shutoff type gas flow control device, comprises base, flow sensor, the post that dams, motor; Described base intermediate lateral offers air flue; Described base side has slot and cylindrical hole; Described flow sensor is arranged in slot, and part stretches into air flue; Described cylindrical hole is arranged on the downstream of slot along the airflow direction of air flue; The described post that dams is arranged in cylindrical hole, and the screw rod rotating shaft of described motor is connected with the post spiral shell core that dams; Described motor can be controlled and dams post sealing or open air flue.
Preferably, described shutoff type gas flow control device, goes back inclusion test controller; Described detection controller is fitted on base, by control line, is connected with motor, flow sensor.
Preferably, dam described in one end of post is connected with the screw flight of motor by spiral shell core screw thread.
Preferably, described motor integral body is fixed on the side of base by fixed support.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Shutoff type gas flow control device described in the utility model scheme can reduce cost of products, and simplified processing process is not very high occasion in impermeability and security, compares and can reach equally accurate control flow with expensive like product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
