Abstract
The utility model belongs to a hydraulic cylinder with a hydraulic control butterfly valve, which mainly comprises an adjusting valve, an intercept valve, a one-way valve, a cylinder bottom, a flange, an overall piston, a cylinder barrel, a shaft pin, a cylinder head, an ear ring and other main parts. Clearances are formed between a throttle lever connected with the adjusting valve and throttle valve holes. The hydraulic cylinder with the hydraulic control butterfly valve has high safety and long service life, and is convenient and simple to operate.
Description
Technical field
The utility model relates to a kind of hydraulic butterfly valve oil hydraulic cylinder.
Background technique
Common hydraulic butterfly valve oil hydraulic cylinder connects the Spielpassung of the throttle valve lever of adjusting valve opening with throttle bore employing H8/f7, and according to the working principle of butterfly valve oil hydraulic cylinder, the hydraulic butterfly valve oil hydraulic cylinder need have the speed speed-regulating function when closing valve; To fasten the throttle valve of pass slowly of straight-through cylinder bottom hydraulic fluid port earlier, make the hydraulic oil that is accumulated in rodless cavity to flow back to system circuit by modulating valve, if it is dead that the quick closing valve throttle valve is closed in operator's misoperation, the hydraulic oil of rodless cavity can't flow back to system circuit, get lodged in hydraulic oil in the modulating valve and can produce high pressure and cause the cylinder bottom blast, cause serious security incident.There is very high potential safety hazard in this common hydraulic butterfly valve oil hydraulic cylinder.
Summary of the invention
Main purpose of the present utility model provides a kind of safe, and is easy to operate simple, the hydraulic butterfly valve oil hydraulic cylinder of long service life.
Main technical schemes of the present utility model is as follows: a kind of hydraulic butterfly valve oil hydraulic cylinder, it comprises modulating valve, shutoff valve, one-way valve, cylinder bottom, flange, solid piston, cylinder barrel, pivot pin, cylinder head, earrings, modulating valve is threaded with cylinder bottom, cylinder bottom is connected with screw with flange, cylinder barrel is threaded with flange, pivot pin and flange with screw be connected, cylinder head and pivot pin with screw be connected, solid piston is threaded with earrings, solid piston is contained in the cylinder barrel; The throttling rod that connects modulating valve is with the space is arranged between throttle bore.
The throttling rod of described connection modulating valve is changed into by original H8/f9 with the space between throttle bore and strengthens 0.2mm.
The utility model has the advantages that: the throttling rod that will connect modulating valve strengthens with the gap between throttle bore, change increasing 0.2mm into by original H8/f9 Spielpassung, even throttling rod is tightened, fluid still can flow back to system circuit by the gap, can avoid because operator's misoperation is closed the quick closing valve throttle valve dead, the hydraulic oil of rodless cavity can't flow back to system circuit, gets lodged in the interior high pressure that produces of modulating valve and causes the cylinder bottom blast, causes serious security incident.This improvement has improved the working life and the Safety performance of hydraulic butterfly valve oil hydraulic cylinder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is a partial enlarged drawing of the present utility model.
Specific embodiment
As shown in the figure, a kind of hydraulic butterfly valve oil hydraulic cylinder, it comprises modulating valve 1, shutoff valve 2, one-way valve 3, cylinder bottom 4, flange 5, solid piston 6, cylinder barrel 7, pivot pin 8, cylinder head 9, earrings 10, modulating valve 1 is threaded with cylinder bottom 4, cylinder bottom is connected with flange 5 usefulness screws, cylinder barrel 7 is threaded with flange, pivot pin 8 and flange with screw be connected, cylinder head 9 and pivot pin with screw be connected, solid piston 6 is threaded with earrings 10, solid piston 6 is contained in the cylinder barrel.The throttling rod that connects modulating valve 1 is with there being the space between throttle bore, its space is changed into by original H8/f9 and strengthens 0.2mm.The cylinder bottom filler opening is by one-way valve 3, and quick closing valve throttle valve 11 closes throttle valve 12 slowly and advances hydraulic oil to rodless cavity, promotes solid piston and moves and pushes valve open; During throttle down, except that the oil-feed of pivot pin filler opening, drag force also can promote solid piston and move, and is too urgent for preventing water impact, and valve closing later stage requirement speed slows down; Be the quick closing valve stroke before in adjusting screw rod does not enter solid piston, close throttle valve slowly this moment and close that rodless cavity hydraulic oil flows back to system circuit by the quick closing valve throttle valve, can use the quick closing valve throttle valve adjustment to manage speed soon; The back is for closing stroke slowly in adjusting screw rod enters solid piston, can use this moment to close the throttling valve regulation slowly and close speed slowly, and by adjusting the speed pass stroke that adjusting screw rod can obtain a kind of scope, make things convenient for actual demand; The throttling rod that connects modulating valve is strengthened with the gap between throttle bore, change increasing 0.2mm into by original H8/f9 Spielpassung, even throttling rod is tightened, fluid still can flow back to system circuit by the gap, can avoid because operator's misoperation is closed the quick closing valve throttle valve dead, the hydraulic oil of rodless cavity can't flow back to system circuit, gets lodged in the interior high pressure that produces of modulating valve and causes the cylinder bottom blast, causes serious security incident.
