The utility model relates to a cartridge inserted valve with the stroke limitation of the position detection of the valve core thereof, which is especially suitable for detecting the opening and closing state of the loop of a hydraulic machinery system. The cartridge inserted valve comprises a valve pocket. One end of the valve pocket is respectively provided with an oil inlet and an oil outlet, while the other end of the valve pocket is provided with a cap nut gasket. The cartridge inserted valve is provided with a control cover plate. The upper side surface of the control cover plate is provided with a control oil way. One end of the control oil way is communicated with a position feedback lever, while the other end of the control oil way is communicated with a valve core. The control cover plate is axially provided with a screw sleeve and an adjusting rod is arranged in the screw sleeve. The side surface of the control cover plate is provided with a connecting sleeve. One end of the connecting sleeve is provided with a return spring, while the other end of the connecting sleeve is provided with a semi-circular rod. One end of the semi-circular rod is in contact with the position feedback lever, while the other end of the connecting sleeve is provided with a signal converter. The intermediate party of the signal converter is provided with a detecting rod. One end of the detecting rod is connected with the semi-circular rod. The cartridge inserted valve with the stroke limitation of the position detection of the valve core thereof is simple in structure, convenient in operation, small in volume, good in signal conversion effect, fully functional and safe and reliable in operation. Therefore, the cartridge inserted valve with the stroke limitation of the position detection of the valve core thereof can be widely adopted as a cartridge inserted valve in the loops of hydraulic machinery systems.
Description
Technical field
The utility model relates to a kind of valve element position that has and detects the travel limits cartridge valve, is specially adapted in the hydraulic-mechanic system loop unlatching and closed condition detected spool stroke restriction cartridge valve equipment.
Background technique
At present, cartridge valve of the prior art has the cartridge valve that has the valve element position measuring ability; The cartridge valve that has the spool stroke restriction is also arranged; Its defective is that two functions do not integrate, if adopt two kinds of valves in use simultaneously, overall volume is big; Complex structure is not easy the failure judgement problem and where appears at when breaking down problem.
Summary of the invention
The purpose of the utility model provides a kind of valve element position that has and detects the travel limits cartridge valve, and it is on cartridge valve, to install control cover plate; Control cover plate axial device screw rod cover is provided with adjustable lever in the middle of the screw rod cover, and the control cover plate side is provided with connecting sleeve, half-round bar, test rod, position feedback bar and signal adapter; When spool moves; Drive the position feedback bar and move, drive half-round bar simultaneously and move, half-round bar drives test rod and moves; After moving to the detection range of signal adapter; Signal adapter just produces signal, can realize that hydraulic system detects the purpose of spool stroke limitation function to the opening and closing state of cartridge valve spool through regulating the open amount that adjustable lever limits spool simultaneously.
The utility model has valve element position detection travel limits cartridge valve and takes following technological scheme to realize, it is to be made up of cartridge valve, control cover plate, adjustable lever, signal adapter and connecting sleeve, and cartridge valve is made up of spool, valve pocket, lid pad and spring; Spool is set in the valve pocket, spring is set in the spool, the position feedback bar is set in the spool; Valve pocket one end is provided with valve filler opening and valve oil outlet respectively, and valve pocket one end is provided with the lid pad, installs control cover plate on the cartridge valve; The control cover plate upper side is provided with the control oil circuit, controls oil circuit one end and is communicated with the position feedback bar, controls oil circuit one end and is communicated with spool; Control cover plate axial device screw rod cover is provided with adjustable lever in the screw rod cover, and the control cover plate side is provided with connecting sleeve; Connecting sleeve one end is nested with Returnning spring, and Returnning spring one end is provided with half-round bar, and half-round bar one end contacts with the position feedback bar; In the middle of the connecting sleeve the other end signalization transducer, signal adapter test rod is set, test rod one end is connected with half-round bar.High-voltage oil liquid is opened spool during use, and spool produces displacement, and position feedback bar and spool are shifted together; Driving half-round bar when the position feedback bar moves moves; Half-round bar moves the drive test rod and moves, and after the detection range that moves to signal adapter, signal adapter just produces signal; Simultaneously can limit the open amount of spool, thereby realize that hydraulic system detects the purpose with the spool stroke limitation function to the opening and closing state of cartridge valve spool through regulating adjustable lever.
The effect that the utility model has valve element position detection travel limits cartridge valve is simple in structure, and easy to operate, volume is little; Signal conversion; Realize safe sender semiotic function, aesthetic in appearance, multiple functional; Safe and reliable to operation, be widely used in the hydraulic-mechanic system loop unlatching and closed condition are detected travel limits cartridge valve equipment.
