Abstract
The utility model discloses an exhaust plant, in particular to a hydraulic cylinder exhaust plant. The hydraulic cylinder exhaust plant comprises a core vent, a spring and steel balls, wherein the core vent comprises a hollow sleeve and a knob; the knob is connected at the upper end of the hollow sleeve; the knob is provided with an air vent mutually communicated with the cavity of the hollow sleeve; the core vent is detachably connected on the cylinder jacket of a hydraulic cylinder; the spring is arranged in the cavity of the hollow sleeve; the steel balls are arranged at the upper end of the spring and are support by the spring; and part of steel balls and the air vent are matched with each other to plug the air vent. The utility model has the advantages of simple structure and oil leakage prevention.
Description
Technical field
The utility model relates to a kind of venting gas appliance, relates in particular to a kind of Exhausted Apparatus of Hydraulic Cylinders.
Background technique
Place, high-order bit in the oil hydraulic cylinder has usually gathered air, and this causes owing to being mixed with air in the fluid.Gathering of air makes the oil hydraulic cylinder bumpy motion, and pressure also can produce adiabatic compression when increasing and the localized hyperthermia that causes.In order to get rid of the air that accumulates in the oil hydraulic cylinder, can respectively adorn a venting plug in high-order bit, the two ends of oil hydraulic cylinder.Be threaded between the cylinder sleeve of venting plug and oil hydraulic cylinder, the bottom of venting plug is tapered, with the air outlet shutoff of oil hydraulic cylinder.During emptying gas, venting plug is unscrewed, the air in the oil hydraulic cylinder is discharged by slit, venting plug tapering and aperture.After air is discharged, need venting plug is twisted extremely, otherwise cause leakage of oil easily and befouling environment.
The model utility content
Technical problem to be solved in the utility model provides a kind of simple in structure, the Exhausted Apparatus of Hydraulic Cylinders of anti-leakage of oil.
The utility model comprises venting plug, spring and steel ball; Described venting plug comprises a cannulated sleeve and a knob, and described knob is connected the upper end of cannulated sleeve, be provided with on the knob one with the exhaust port that is interconnected of tube chamber of above-mentioned cannulated sleeve; Above-mentioned venting plug removably is connected on the cylinder sleeve of oil hydraulic cylinder; Described spring is arranged in the tube chamber of cannulated sleeve, and steel ball places the upper end of spring to be supported by spring; Part steel ball and above-mentioned exhaust port cooperatively interact the exhaust port shutoff.
During exhaust, apply certain downforce to steel ball, steel ball is depressed, and the air in the oil hydraulic cylinder is discharged by the exhaust port that is arranged on the knob immediately.After exhaust is finished, cancel above-mentioned downforce, spring recovers deformation steel ball is lifted, and steel ball is again with the exhaust port shutoff.Of the present utility model simple in structure, avoided existing venting gas appliance owing in time not tightening the defective that venting plug causes leakage of oil, befouling environment.
Preferably, on the outer side surface of the cannulated sleeve of described venting plug outside thread is set, venting plug is threaded on the cylinder sleeve.
Description of drawings
Fig. 1 is the structural representation of Exhausted Apparatus of Hydraulic Cylinders.
Embodiment
As shown in Figure 1, the Exhausted Apparatus of Hydraulic Cylinders in the present embodiment comprises venting plug 1, spring 2 and steel ball 3.
Described venting plug 1 comprises a cannulated sleeve 1-1 and a knob 1-2.Described knob 1-2 is connected the upper end of cannulated sleeve 1-1, and on knob 1-2, be provided with one with the exhaust port that is interconnected of tube chamber of above-mentioned cannulated sleeve 1-1.On the outer side surface of cannulated sleeve 1-1 outside thread is set, above-mentioned venting plug 1 is threaded on the cylinder sleeve 4.
Above-mentioned spring 2 is arranged in the tube chamber of cannulated sleeve 1-1, and steel ball 3 places the upper end of spring 2 to be supported by spring 2.Part steel ball 3 cooperatively interacts the exhaust port shutoff with above-mentioned exhaust port.During exhaust, apply certain downforce for steel ball 3, steel ball 3 is depressed, and the air in the oil hydraulic cylinder is discharged by the exhaust port that is arranged on the knob 1-2 immediately.When cancelling above-mentioned downforce, spring 2 recovers deformation steel ball 3 is lifted, and steel ball 3 is again with the exhaust port shutoff.
