Description
Technical field
This utility model relates to a kind of electronic intake valve of screw air compressor.
Background technology
The open and close of existing screw machine intake valve are all controlled by cylinder, medium is driven to be usually cleaner compressed air or mixed oil and gas, therefore seal request partly is controlled for intake valve higher, after medium is contaminated, compressed air can cause cylinder piston blocking, sealing member accelerated wear test containing larger particles pollutant, so that intake valve can not be operating normally.Existing screw machine intake valve employing mechanical type proportioning valve jointly acts on cylinder and intake valve is carried out opening adjustment, due to more unavoidable reasons such as the frictional force of sealing member or mechanical type proportioning valve manufacture processing, causing controlling precision comparison during intake valve opening adjustment poor, there is delay phenomenon in feedback.
Utility model content
The purpose of this utility model, is to overcome above-mentioned limitation, thus it is relatively low to provide a kind of intake valve to control part seal request ratio, and intake valve control accuracy is high, and response speed is fast, and intake valve controls the electronic intake valve of convenient screw air compressor.
The purpose of this utility model is achieved through the following technical solutions: a kind of electronic intake valve of screw air compressor, including valve body, valve body is provided with air inlet, valve body is provided with motor, driven by motor motor gear rotates, valve body is provided with driving gearshaft, driving gearshaft is provided with travelling gear, travelling gear engages with motor gear, it is provided with valve plate in valve body air inlet, valve plate is bolted with valve rod, connect on valve rod and have sensor assembly and driven pulley, driven pulley engages with travelling gear, integrated circuit cover plate it is provided with outside valve body, integrated circuit cover plate is provided with control circuit terminals, valve plate regulative mode can use opened loop control or closed loop control, it is controlled by screw machine PLC.
Preferably, valve body is provided with bleeder valve interface and bleeder valve valve rod, and bleeder valve valve rod is provided with bleeder valve and drives gear, and bleeder valve drives gear to engage with driven pulley.
Preferably, valve body lower portion is connected by sealing gasket check-valves, is provided with check valve plate and balancing weight in check-valves, and check-valves lower end connects head air inlet.
In sum, this utility model has the advantage that intake valve control part seal request ratio is relatively low；Intake valve control accuracy is high, and response speed is fast；Intake valve controls convenient, and screw machine PLC uses open loop or closed loop control to intake valve, and the duty of intake valve intuitively can show at control panel；The bleeder valve that this money valve carries also can realize high accuracy by the signal of telecommunication and control.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
nullSuch as Fig. 1、The electronic intake valve of a kind of screw air compressor shown in 3，Including valve body 1，Valve body 1 is provided with air inlet，Valve body 1 is provided with motor 11，Motor 11 drive motor gear 10 rotates，Valve body 1 is provided with driving gearshaft 9，Driving gearshaft 9 is provided with travelling gear 8，Travelling gear 8 engages with motor gear 10，It is provided with valve plate 16 in valve body 1 air inlet，Valve plate 16 is connected by bolt 17 with valve rod 7，Connect on valve rod 7 and have sensor assembly 6 and driven pulley 5，Driven pulley 5 engages with travelling gear 8，Integrated circuit cover plate 2 it is provided with outside valve body 1，Integrated circuit cover plate 2 is provided with control circuit terminals，Valve body 1 is provided with bleeder valve interface and bleeder valve valve rod 4，Bleeder valve valve rod 4 is provided with bleeder valve and drives gear 3，Bleeder valve drives gear 3 to engage with driven pulley 5；Valve body 1 bottom is connected by sealing gasket 12 as shown in Figure 2,4 check-valves 13, is provided with check valve plate 14 and balancing weight 15 in check-valves 13, and check-valves 13 lower end connects head air inlet.
When screw machine needs air inlet, motor 11 drives motor gear 10 band nutating gear 8 and driven pulley 5, and band ovable valve stem 7 rotates, and opens valve plate 16, and bleeder valve is closed under gear driven, and intake valve loads；When screw machine air inflow needs to be adjusted, motor 11 drive motor gear 10 band nutating gear 8 and driven pulley 5 strengthen or reduce valve plate 16 opening angle, realizing air inlet adjustment, opening angle can be carried out open loop or closed loop control intake valve in real time by screw machine PLC according to pressure at expulsion size；When screw machine unloads, motor 11 drives gear, band ovable valve stem 7 backwards rotation, and valve plate 16 is closed, and opens bleeder valve while valve plate 16 is closed, and intake valve unloads.This valve can use separately as intake valve, it is possible to form the screw machine motorized non-return valve of band check function with check-valves 13.
