Abstract
Provided is an air control hydraulic one-way valve. The air control hydraulic one-way valve mainly comprises a threaded inserting mounting one-way valve, a valve body and a bonnet. An oil inlet and an oil outlet are formed in the valve body, the bonnet and the valve body are connected in a fastened mode through a screw, a removing air cylinder piston, a push pin reset spring and a removing push pin are arranged in a cavity inside the valve body and a cavity inside the bonnet in sequence from inside to outside, one end of the push pin reset spring is connected with the removing air cylinder piston, the other end of the push pin reset spring is connected with the removing push pin, the threaded inserting mounting one-way valve is installed in the cavity of the valve body in an inserting mode, the outer end of the threaded inserting mounting one-way valve is sealed through a sealing ring of the threaded inserting mounting one-way valve, the inner end of the threaded inserting mounting one-way valve is arranged in the cavity of the valve body, and is close to the removing push pin, and a one-way removing air inlet is formed in the bonnet, and is communicated with the removing air cylinder piston. According to the air control hydraulic one-way valve, due to the facts that the existing threaded inserting mounting one-way valve is adopted, and a pneumatic structure is used for removing one-way action to achieve both-way communication of the air control hydraulic one-way valve, the phenomenon of oil mixing is prevented. Due to the fact that air pressure is used for pushing hydraulic oil to carry out work, a hydraulic station is omitted, and manufacturing cost and use cost are greatly reduced.
Description
Technical field
The present invention relates to a kind of hydraulic control component, be specifically related to a kind of Pneumatic and hydraulic one-way valve.
Background technique
Pilot operated check valve is to rely on the control hydrodynamic pressure, can make the valve of one-way valve reverse circulated.Traditional Pilot operated check valve, need remove individual event valve with high-pressure and hydraulic oil and realize two-way admittance, and removing the hydraulic oil of end does not have seal ring because remove piston, can when removing one-way function, penetrate into the one-way valve end, cause string oil, be fine when using hydraulic station to carry out fuel feeding, but the oil cylinder that operates below low pressure 1Mp uses hydraulic station will improve manufacturing cost and use cost greatly.
Summary of the invention
The invention provides a kind of Pneumatic and hydraulic one-way valve, to solve string oil and the high problem of hydraulic station fuel feeding cost that Pilot operated check valve exists.
The present invention mainly is made up of thread cartridge one-way valve, valve body and valve gap, valve body arranges filler opening and oil outlet, solving the technological scheme that its technical problem adopts is that valve gap is connected fastening with valve body by screw, be provided with successively from inside to outside in the cavity of valve body and valve gap inside and remove cylinder piston, push pin Returnning spring and releasing pushed pin, Returnning spring one end of pushing pin is connected with the releasing cylinder piston, and the Returnning spring the other end of pushing pin is pushed pin with releasing and linked to each other; The thread cartridge one-way valve is inserted in the cavity of valve body, thread cartridge one-way valve outer end utilizes the seal ring that carries to seal, push pin near removing in the cavity of valve body in the inner of thread cartridge one-way valve, valve gap is provided with unidirectional releasing suction port and communicates with the releasing cylinder piston.
Above-mentioned releasing is pushed pin and is pushed pin the depressurization circle is set between the Returnning spring, and the depressurization circle can prevent that hydraulic oil from entering in the releasing cylinder.
Arrange between above-mentioned releasing cylinder piston and the valve gap and remove the cylinder piston packing.
Apparatus of the present invention working principle: when the needs cylinder action (stretch out or return), the filler opening oil pressure increases, the conducting of thread cartridge one-way valve, hydraulic oil enters oil cylinder from oil outlet, the oil cylinder piston setting in motion, when the reaction force that is subjected to when oil cylinder increases to a certain degree, thread cartridge one-way valve locking, prevent that hydraulic oil from refluxing, and oil cylinder can not produced retreat; When the needs oil cylinder carries out counteragent (return or stretch out), under the effect of solenoid valve, unidirectional releasing suction port air pressure increases, the promotion releasing is pushed pin and is removed the cylinder piston and move to thread cartridge one-way valve direction, remove single effect, the thread cartridge one-way valve forms two-way admittance, when the oil cylinder opposite side has pressure, originally the hydraulic oil that entered oil cylinder flows out through oil outlet, thread cartridge one-way valve and filler opening, and oil cylinder resets.
When removing, the Returnning spring of pushing pin is compressed, when releasing finishes after oil cylinder resets, under the effect of solenoid valve, unidirectional releasing suction port no longer includes air pressure, and the Returnning spring resilience of pushing pin that is compressed resets, and drive releasing is simultaneously pushed pin and removed the cylinder piston reset.
Compare with existing technology, apparatus of the present invention have been used existing thread cartridge one-way valve, and use pneumatic structure to remove the two-way admittance that single effect realizes one-way valve, prevented the oily phenomenon of string, using air pressure to promote hydraulic oil does work, save hydraulic station, greatly reduced manufacturing cost and use cost.
