Summary of the invention
The purpose of this utility model is to propose a kind of valve stroke control device for opening, and is controlling more accurately the unlatching of valve in the Port Steady Flow test, more convenient, obtain test figure fast and accurately.
Port Steady Flow of the present utility model test comprises one by two support bars and is set up in " П " shape support that the guide rod of described two support bar top consists of with the valve opening device, described guide rod is provided with the slide block that can move along guide rod, the bottom of described slide block is fixed with an angle scale, described angle scale is provided with the runing rest that can rotate and can be fixed at angle scale a certain angle, described runing rest is provided with a valve stem and links to each other, and the governor motion that can make this valve stem raise or reduce.
In the engine air passage flow stabilizing test, at first the valve opening device is fixed on steady flow testbed by " П " shape support, then rotate runing rest, adjusting is installed in the angle of the governor motion on this support, when governor motion and valve stem are identical with measured cylinder cap or core box valve inclination angle, runing rest is fixed on the angle scale; Then along the guide rod moving slider, thereby it is coaxial that valve stem is adjusted to engine valve to be measured, at last valve stem and engine valve to be measured fixed, and can regulate and control by governor motion the unlatching lift of valve.
Further, described governor motion is stepper motor, and the motor shaft of described stepper motor is provided with screw thread, and valve stem is provided with the screw thread that cooperates with motor shaft, form lead screw pair between motor shaft and the valve stem, so that the rotation of motor shaft is converted into the axially-movable of valve stem.By the cooperation of lead screw pair, can utilize stepper motor accurately to control the lift of valve, and can guarantee that valve stroke keeps stable in experimentation, thus the accuracy that improves test figure.
Further, described guide rod one end is provided with swing handle, and guide rod is set up in the top of two support bars rotationally, and the surface of guide rod is provided with screw thread; Be provided with the internal thread with the guide rod threaded engagement in the described slide block, the rotation of described guide rod drives slide block through threaded engagement and moves along guide rod.By swing handle, the rotation of guide rod can be converted into the translation of slide block, thereby can adjust easily the position of slide block on guide rod.
Further, be carved with scale on the described angle scale, to observe intuitively and to regulate the inclination angle of governor motion and valve stem, make it identical with measured cylinder cap or core box valve inclination angle.
Further, the both sides of described angle scale respectively are provided with a runing rest, simultaneously two valves are tested with convenient.
Port Steady Flow test of the present utility model is simple, compact with the valve opening apparatus structure, reasonable in design, valve opening lift that can the true reappearance engine, the more intake process of real simulation engine, make test figure that directive significance more be arranged, and improved work efficiency and test accuracy.
