Description
Technical field
The present invention relates to hydraulic cartridge valve and change technical field, concrete is that a kind of universal hydraulic cartridge valve is changed instrument.
Background technology
The inserted valve generally using in hydraulic system at present mainly comprises spool and valve pocket, the outside design of valve pocket sealing mechanism is used for sealing fluid, prevent the outside leakage of oil of valve pocket, valve pocket coordinates very tight with valve platform endoporus, cause inserted valve to be arranged on after valve platform endoporus not quick detachable, can not inserted valve be taken out from valve platform endoporus by free-hand or simple instrument, and utilize common instrument likely to damage the surface of valve sleeving inner wall or valve platform endoporus, equipment is caused to unnecessary damage.
Known hydraulic cartridge valve replacing instrument has expansion set pipe and puts two kinds of oblique swing arms, but these two kinds of instrument distance adjustment scopes are less, can only be by changing the expansion set assembly of corresponding size or putting oblique swing arm and could change by adaptive different specification size inserted valve.Along with development and the application of high-pressure high-flow hydraulic technique, increasing hydraulic system need to be used the inserted valve of plurality of specifications size simultaneously, and expansion set pipe and the oblique swing arm instrument scope of application of pendulum are little, and operating efficiency is low.The existing weak point of prior art that Here it is.
Summary of the invention
Technical problem to be solved by this invention, is exactly for the existing deficiency of prior art, and provides a kind of universal hydraulic cartridge valve to change instrument, and it is applied widely, operating efficiency is high.
This programme is achieved by the following technical measures: a kind of universal hydraulic cartridge valve is changed instrument, comprise that two bottoms are provided with the pull bar of drag hook, tie bar space governor motion and boosting mechanism, the pressing plate that described tie bar space governor motion comprises force bearing plate and coordinates with force bearing plate, described pull bar is between force bearing plate and pressing plate, and described force bearing plate and pressing plate are bolted.
Above-mentioned force bearing plate is " recessed " character form structure, and described pressing plate is positioned at the groove of force bearing plate.
The cross section of above-mentioned pressing plate is rectangular configuration.
The cross section at above-mentioned pull bar middle part is cydariform.Pull bar to clamp position milling flat, by bolt, pull bar is fastened between force bearing plate and pressing plate, fastening convenience, fastening effective, the cross section at pull bar middle part is cydariform, fixing can facilitate pull bar upper-lower position to adjust time.
The top of above-mentioned drag hook is arc transition structure.In use, conveniently find through flow hole or the valve pocket inward flange of inserted valve accurately, can slow down the collision of drag hook top to inserted valve inwall, avoid scratching inserted valve.
Above-mentioned drag hook is made up of aluminium alloy.Drag hook aluminium alloy material, the hardness of aluminium alloy is lower than the hardness of hydraulic cartridge valve itself, the damage to inserted valve through flow hole or valve pocket inward flange while effectively avoiding changing inserted valve.
The cross section of above-mentioned pull bar is L shaped structure.
Above-mentioned boosting mechanism comprises two screw rods, is symmetrically arranged with two screwed holes that mate with screw rod on described force bearing plate.Screw rod precession screwed hole, screw rod bottom acts on the valve platform position outside the size of inserted valve outer ring, evenly afterburning to two screw rods, and inserted valve is taken out in valve platform.
Beneficial effect of the present invention can be learnt from above-mentioned technical scheme: a kind of universal hydraulic cartridge valve is changed instrument, comprise that two bottoms are provided with the pull bar of drag hook, tie bar space governor motion and boosting mechanism, the pressing plate that described tie bar space governor motion comprises force bearing plate and coordinates with force bearing plate, described pull bar is between force bearing plate and pressing plate, and described force bearing plate and pressing plate are bolted.Boosting mechanism acts on the valve platform position outside inserted valve, and when use, bolt is by pull rod pressing, and the drag hook on pull bar takes out inserted valve in valve platform; According to the distance between two pull bars of inserted valve specification adjusting to be replaced and the position of pull bar in the vertical direction, can realize the quick-replaceable of the inserted valve of different specification size, improve operating efficiency; This inserted valve replacing tool construction is simple, accurate positioning, easy to use.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1 and Figure 2: a kind of universal hydraulic cartridge valve is changed instrument, comprise that two bottoms are provided with the pull bar 1 of drag hook 1.1, tie bar space governor motion and boosting mechanism, the pressing plate 3 that described tie bar space governor motion comprises force bearing plate 2 and coordinates with force bearing plate 2, described pull bar 1 is between force bearing plate 2 and pressing plate 3, and described force bearing plate 2 is connected by bolt 5 with pressing plate 3.Boosting mechanism acts on the valve platform position outside inserted valve, and when use, bolt 5 holds out against pull bar 1, and the drag hook 1.1 on pull bar 1 takes out inserted valve in valve platform; According to the distance between two pull bars 1 of inserted valve specification adjusting to be replaced and the position of pull bar 1 in the vertical direction, can realize the quick-replaceable of the inserted valve of different specification size, improve operating efficiency; This inserted valve replacing tool construction is simple, accurate positioning, easy to use.
The described force bearing plate 2 of stating is for " recessed " character form structure, and pressing plate 3 is positioned at the groove of force bearing plate 2.
