Abstract
The utility model relates to a mechanical valve with stroke control function, which is used for a hydroelectric power generation running simulation system, and is characterized by comprising the mechanical valve and a variable resistor, wherein a support is fixedly connected on a valve body of the mechanical valve, the variable resistor is fixedly connected on the support, a sliding rod is arranged in a guide sleeve of the support, a stroke adjusting shift fork which is fixedly connected with the rod end of the sliding rod is connected with an annular groove of a valve rod of the mechanical valve, and the shift fork of the sliding rod is connected with a sliding contact of the adjustable resistor. The mechanical valve can regulate the value of the variable resistor in real time through the manual control of the stroke of the valve rod of the mechanical valve, provide a control signal for a computer through the change of the value of the variable resistor, and further lead the open degree of a valve icon displayed on a display screen of the computer to be consistent with the actual open degree of mechanical valve through the manual control, so as to achieve the simulation training purpose, thus having the advantages of simple structure, capability of leading the training operation to be consistent with the actual operation, excellent training effect and the like.
Description
Technical field:
The utility model is a kind of mechanical valve that has Stroke Control that is used for hydraulic power plant's operating simulation system.
Background technology:
Existing hydropower operating simulation system helps trainee's actual operational capacity and troubleshooting capability, this system adopts virtual disk platform technology, component technology usually, what can show hydraulic power plant on computers returns Pan Tai such as the other dish of screen, imitation screen, machine, backup system, and with the supervision in the mode Simulated Water power station of figure, control environment.Make the operating simulation system that generates electricity from water power, the student who is trained is in operating process, can only simulate the aperture of by-pass valve control by the icon of keyboard and Genius mouse control system valve, because the student that trained can not be is directly realized control to valve opening by operated valve, its weak point is, lack real operating handle, the training operation is disconnected mutually with practical operation, be difficult to reach the effect of training.
Summary of the invention:
Problem to be solved in the utility model is, existing mechanical valve, variohm are carried out organic assembling, and a kind of mechanical valve that has Stroke Control simple in structure is provided, and can make the training operation consistent with practical operation, the enhancement training effect.
The technical scheme that solves its technical matters employing is, a kind of mechanical valve that has Stroke Control, it is characterized in that: it comprises mechanical valve, variohm, on the valve body of mechanical valve, be fixed with support, variohm is connected on the support, in the orienting sleeve of support slide bar is housed, the stroke adjustment shift fork that the slide bar rod end is connected is connected with the annular groove of mechanical valve valve rod, and the shift fork of slide bar is connected with the slider of adjustable resistor.
The mechanical valve that has Stroke Control of the present utility model can be come the variable-resistance numerical value of real-time regulated by the valve rod travel of manual control machine tool valve, provide control signal by variable-resistance numerical value change to computing machine, and then make the aperture of the valve icon that shows on the computer display consistent with the actual aperture of manual control machine tool valve, realize real-time demonstration, the relation curve of aperture that draws by experiment and pressure or flow, calculate due pressure or flow by real-time again being reflected on the actual table meter of computer interface, to reach the purpose of emulation training, have simple in structure, advantages such as it is consistent with practical operation that training is operated, and result of training is good.
Description of drawings:
Fig. 1 is that the mechanical valve structure master who has Stroke Control looks synoptic diagram.
Fig. 2 is the schematic top plan view of Fig. 1.
Fig. 3 is an A-A cross-sectional schematic among Fig. 2.
Among the figure: 1 mechanical valve, 2 operation handwheels, 3 valve rods, 4 clamp nuts, 5 connectors, 6 valve bodies, 7 supports, 8 orienting sleeves, 9 slide bars, 10 shift forks, 11 stroke adjustment shift forks, 12 variohms, 13 sliders.
Embodiment:
With reference to Fig. 1-3, the mechanical valve that has Stroke Control of the present utility model comprises mechanical valve 1, variohm 12, and mechanical valve 1 and variohm 12 are the commercially available prod.Mechanical valve 1 has valve body 6, operation handwheel 2, valve rod 3, clamp nut 4 and connector 5, valve body 6 is connected on the pipeline, valve body 6 is connected with connector 5, valve rod 3 is contained in the connector 5 and by being threaded, the outer end of valve rod 3 is fixed with operation handwheel 2, and the spool of valve rod 3 matches with the die cavity of valve body 6.On the valve body 6 of mechanical valve 1, be fixed with support 7, variohm 12 is connected on the support 7, in the orienting sleeve 8 of support 7, slide bar 9 is housed, the stroke adjustment shift fork 11 that slide bar 9 rod ends are connected is connected with the annular groove of mechanical valve valve rod 3, and the shift fork 10 of slide bar 9 is connected with the slider 13 of adjustable resistor 12.
Brief description has the principle of work of the mechanical valve of Stroke Control: the aperture that manual rotary manipulation handwheel 2 is regulated the valve body 6 of mechanical valve 1, that is: adjust pressure or flow, stroke adjustment shift fork 11 drive slide bars 9 move right simultaneously, the slider 13 that drives adjustable resistor 12 moves right, resistance value by adjustable resistor 12 changes to computing machine provides control signal, and then make the aperture of the valve icon that shows on the computer display consistent with the actual aperture of manual control machine tool valve 1, realize real-time demonstration, the relation curve of aperture that draws by experiment and pressure or flow, calculate due pressure or flow by real-time again being reflected on the actual table meter, of computer interface to reach the purpose of emulation training.
