Summary of the invention
Goal of the invention of the present invention is to provide the improvement structure of water-jet cutting machine water under high pressure production sealing property, the durable mechanism between the each connector of a kind of easy guarantee.
The present invention realizes like this, comprise the hydraulic cylinder main body with the hydraulic cylinder cavity connecting, be arranged on the piston in hydraulic cylinder cavity, by be screwed in the end cap that is bolted to hydraulic cylinder cavity two ends of hydraulic cylinder main body side through end cap screw thread, be fixed on the hydraulic cylinder on end cap, reversal valve, between end cap and hydraulic cylinder main body side, be provided with sealing ring, the installed surface that hydraulic cylinder main body upper side is reversal valve, reversal valve is fixed on this installed surface, in hydraulic cylinder main body, be provided with two oil circuits, a wherein outlet of two oil circuits lays respectively at the two ends sidewall of hydraulic cylinder cavity, another outlet of two oil circuits lays respectively at installed surface and two oily access port corresponding positions reversal valve of hydraulic cylinder main body, between another outlet of oil circuit and the oily access port of reversal valve, be provided with sealing ring, on end cap, be provided with the perforation with hydraulic cylinder cavity coaxial line, perforation segmentum laterale is screw-threaded counterbore, the wherein threaded one end of hydraulic cylinder is screwed in screw-threaded counterbore, between the end face of screw-threaded counterbore and hydraulic cylinder end face, be provided with sealing ring, in perforation, be provided with sealing ring, on the both sides axis of piston, be fixed with piston rod, piston rod enters in hydraulic cylinder through the sealing ring in perforation, the water inlet of hydraulic cylinder, outlet is respectively by check valve and water source, water under high pressure user is connected, be provided with piston inductor at the two ends of hydraulic cylinder cavity.When work, reversal valve control hydraulic oil passes in and out the two ends of hydraulic cylinder cavity in turn, the information that piston inductor puts piston in place is delivered to control device, distribution by control device control reversal valve to hydraulic oil, the piston rod of piston driving both sides moves forward and backward in hydraulic cylinder, by the water supercharging entering in hydraulic cylinder, then by check valve, water under high pressure is delivered on user.Owing to adopting the oil circuit and the hydraulic cylinder cavity entirety that are connected with reversal valve to connect in aggregates, ensure like this installed surface smooth of reversal valve, ensure the sealing that reversal valve is connected with installed surface, because end cap obtains end face by the hydraulic cylinder cavity that is bolted to that is screwed in hydraulic cylinder main body side through end cap screw thread, easily realize hydraulic cylinder cavity, hydraulic cylinder is positioned on same axis, avoided piston rod to the inhomogeneous of sealing ring actuating pressure and damage sealing ring.
The present invention compared with the prior art, have advantages of sealing property between the each connector of easy guarantee, durable.
