Abstract
An anti-explosion vacuum transparent counting cup for pneumatic oil pump, the utility model is fabricated in the process that the upper end and lower end of the cup wall with graduation are sealed with the upper cover and lower cover of the counting-cup by sealing ring to form into a transparent vacuum counting-cup. The inside of the transparent vacuum counting-cup is equipped with one piece center tube sticking out two ends, the wall of the tube, which is close to the lower cover of the cup where the center tube is located, is provided with two oil outlet holes. The center tube is located at the lower end of the lower cover of the cup and connected with a ball valve by a sealing ring and flat gasket, which is used for connecting a oil storage tank of the pneumatic oil pump. The upper cover of the transparent vacuum counting-cup is provided with an oil inlet hole which can connect with oil suction pipe. A vacuum generator, which can prevent a explosion resulting from overpressure in the cup, is arranged on the upper end of the center tube where the center tube is higher than the upper cover of the transparent vacuum counting-cup of pneumatic oil pump.
Description
Technical field
The utility model is an automotive service equipement--vacuum cup parts of pneumatic pumping unit especially can prevent the vacuum cup that pneumatic pumping unit is blasted.
Background technology
At present, the transparent measuring cup of known pneumatic pumping unit vacuum if the staff will discharge the oil in the oil pumper, need be closed valve between vacuum cup and the oil storage bottle, strengthens the air pressure of oil pumper oil storage bottle then, can discharge oil.But because the human operational error forgets valve-off during pressurization, the vacuum cup of pneumatic pumping unit is blasted with regard to as easy as rolling off a log so.
Summary of the invention
In order to overcome the defective of the transparent measuring cup of existing pneumatic pumping unit vacuum, prevent that vacuum cup from blasting under the situation of maloperation-forget valve-off the staff, jeopardize staff's life security, the utility model provides a kind of new transparent measuring cup of pneumatic pumping unit vacuum.
The technical scheme that its technical matters that solves the utility model adopts is: seal, fix transparent measuring cup of vacuum of formation by O-ring seal and measuring cup upper press cover, measuring cup lower cover respectively at a transparent graduated wall of cup upper/lower terminal.Establish one and pass the two ends pipe core in the transparent measuring cup of vacuum, pipe core is positioned on the tube wall of close measuring cup lower cover of cup establishes two oil outlets.The lower end that pipe core is positioned at the measuring cup lower cover is connected on the ball valve by O-ring seal and plain cushion, is used to connect the storage tank of pneumatic pumping unit.An oil-in that can connect fuel sucking pipe is arranged on the upper press cover of the transparent measuring cup of vacuum.A vacuum generator is adorned in the upper end that is higher than vacuum amount transparent bowl cover at the pipe core of the transparent measuring cup of vacuum of pneumatic pumping unit.Vacuum generator is six hollows, the screwed cylinder of upper end journey; Around the vacuum generator three holes are arranged, load onto vacuum meter for one, be used for measuring the air pressure of vacuum cup; Load onto screw in Du of river in Shangdong Province for one, be used for outwards bleeding, make vacuum cup be in vacuum state; Load onto pin in Du of river in Shangdong Province for one, the other end of pin is loaded onto sound suppressor in Du of river in Shangdong Province; Be provided with the anti-explosion exhaust hole around the wall upper end, chamber of vacuum generator; O-ring seal is housed and dials pearl 1 in the chamber of the arachnoid part of vacuum generator, block with plug above, to block the pearl of dialling on top; The vacuum generator inner chamber is equipped with one dials the pearl valve; Dialling the pearl valve is six hollows, and the upper end is screwed cylinder, is provided with O-ring seal in the lumen, dials pearl 2 and jump ring; When group pearl valve is loaded on the inner chamber of vacuum generator, and between the inwall of vacuum generator the space is arranged; When the vacuum generator is installed on pipe core, dials the pearl valve and be arranged in pipe core.Like this, when vacuumizing, close naturally and be close to O-ring seal and play sealing function thereby dial pearl 1; Air will be from the side of dialling pearl 2 by and be discharged from vacuum cup; When vacuum amount transparent cup is in vacuum state, dials pearl 1 and all be close to O-ring seal, thereby play sealing function with group pearl 2; Dial pearl 2 and backed down by air pressure when measuring cup enters pressurized air, gas enters vacuum generator from dialling pearl 2 sides, and backs down and dial pearl 1 in the vacuum generator, and gas is from dialling pearl 1 side by entering the outside emission gases of vent port, thereby reaches explosion-proof effect.
The beneficial effects of the utility model are, when the operating personnel of pneumatic pumping unit carry out oil extraction work, forget under the situation of closing ball valve and pressurizeing, and can avoid vacuum cup to produce blast owing to pressure is excessive.
