The content of the invention
Technical problem solved by the invention is to provide a kind of integral multitandem valve, by adopting built-in pressure in banked direction control valves
The mode of force compensating flow control valve and hydraulic lock solves shortcoming present in background technology.
Technical problem solved by the invention employs the following technical solutions to realize：
A kind of integral multitandem valve, including inlet valve connection 1, multiple operating valves connection 2 and an oil return valve connection 4；It is the plurality of
Operating valve connection 2 is arranged between the inlet valve connection 2 and oil return valve connection 4；Inlet valve connection 1, the operating valve connection 2 and oil return valve connection
4 is monolithic construction；The inlet valve connection 2 is provided with oil inlet P 7, and the oil return valve connection 4 is provided with oil return inlet T 5；It is described many
Often connection arranges two actuator ports A6, B3 to individual operating valve connection 2；It is characterized in that：Be provided with operating valve connection 2 hydraulic lock 8,
Pressure compensated flow control valve 11, commutation valve rod assembly 13, and from top to bottom set gradually.
Further, 2 setting valve pockets in the operating valve connection, the hydraulic lock 8, hydraulic pressure lock control push rod 10, pressure are mended
Flow control valve 11, commutation valve rod assembly 13 are repaid within valve pocket, end cap 14 and reversing gear 12 are connected by screw
Connect and be placed in outside valve pocket.
Further, the pressure compensated flow control valve 11 is throttled by being threaded on valve pocket on valve pocket 19
Plug 15 is threadedly attached in valve element 16, and valve element 16 is sleeved in valve pocket 19, and withstands the one end of spring 17, spring 17 it is another
End arranges plug 18.
Further, the cylindrical cannelure g, valve pocket 19 of setting of the valve element 16 is provided with aperture h.
Further, the end cap 14 and reversing gear 12 are connected by screw and are placed in outside valve pocket.
The integral multitandem valve range of application includes：Side-mounted garbage compression vehicle, rollover bucket mechanism, shoveling mechanism, after
Door switch mechanism.
A kind of method of work of integral multitandem valve is：
Including following three kinds of working conditions：
The first, when the valve rod assembly 13 that commutates is in neutral position, the pressure oil Jing a oil ducts from the input of oil inlet P 7 are straight
Connect to flow to c oil ducts and oil return inlet T 5 and connect and flow back to system fuel tank, the cavity pressure of hydraulic jack two acts on the right and left of hydraulic lock 8
On check valve 9, each oil cylinder is in the lock state；
Second, when operating valve joins 2 reversing gears 12, and commutation valve rod assembly 13 is placed in left position, from oil inlet P 7
The pressure oil Jing a oil ducts of input flow to b2 oil ducts, and now, the hydraulic oil of b2 oil ducts directly opens the left side check valve of hydraulic lock 8
9, approach oil duct d2 flows to working hole B3 and enters operating cylinder, while hydraulic oil promotes hydraulic lock control-rod 10 to push hydraulic lock 8 open
The right check valve 9, another chamber hydraulic oil Jing actuator port A6 of oil cylinder, oil duct d1, b1 enter oil duct c and oil return inlet T 5 connects stream
System fuel tank is returned, meanwhile, the hydraulic oil of b2 oil ducts controls valve 11 also into left pressure compensating flowrate, acts on valve element 16 and throttles
Fill on 15 ends, and overcome the spring force of the generation of spring 17, the interstitial hole oil duct e of Jing valve elements 16, the aperture h of valve pocket 19 remain constant
Pressure reduction is not flowed to oil duct c cocurrent oil sump tanks by load interference, reduces the hydraulic oil into operating cylinder；
The third, when operating valve joins 2 reversing gears 12, and commutation valve rod assembly 13 is placed in right position, from oil inlet P 7
The pressure oil Jing a oil ducts of input flow to b1 oil ducts, and now, the hydraulic oil of b1 oil ducts directly opens the right one-way valve of hydraulic lock 8
9, approach oil duct d1 flows to working hole B3 and enters operating cylinder, while hydraulic oil promotes hydraulic lock control-rod 10 to push hydraulic lock 8 open
Left side check valve 9, another chamber hydraulic oil Jing actuator port A6 of oil cylinder, oil duct d2, b2 enter oil duct c and oil return inlet T 5 connects stream
System fuel tank is returned, meanwhile, the hydraulic oil of b1 oil ducts controls valve 11 also into right atrial pressure compensating flowrate, acts on valve element 16 and throttles
Fill on 15 ends, and overcome the spring force of the generation of spring 17, the interstitial hole oil duct e of Jing valve elements 16, the aperture h of valve pocket 19 remain constant
Pressure reduction is not flowed to oil duct c cocurrent oil sump tanks by load interference, reduces the hydraulic oil into operating cylinder.
In such scheme, because valve pocket is built-in with pressure compensated flow regulating valve 11, b2 oil duct hydraulic oils act on valve element
On the end of 16 orifice plug 15, due to the interstitial hole of valve element 16 and spring cavity f, the cylindrical cannelure g of valve element 16, the aperture h of valve pocket 19, oil duct c
Communicate, therefore b2 oil duct high-pressure oil flows overcome the power that spring 17 is produced to the end motion of plug 18 when crossing orifice plug 15, when outside valve element 16
When annular groove g will close 19 aperture h of valve pocket, the pressure at two ends of valve element 16 is equal, and under spring force, valve element 16 is opened again
Open, so valve element 16 remains that constant pressure difference is not disturbed by load, under the pressure reduction, hydraulic oil is constant by orifice plug
15 apertures, flow through oil duct c and return system fuel tank, so as to reduce hydraulic oil of the b2 oil ducts into actuator port B3 to hydraulic jack；Instead
It, principle is the same when commutation valve rod assembly 13 is placed in right position, enters fuel-displaced in opposite direction.
In above-mentioned two situations, if the operating valve connection of commutation is corresponding for bucket mechanism of turning on one's side, bucket oil cylinder speed of turning on one's side
Controllable does stretching motion, drives Gua Tong mechanisms to catch on refuse receptacle and lifts and be poured onto compartment, transfers after the completion of toppling over to ground,
Midway can locking at any time；If it is shoveling mechanism that the operating valve connection of commutation is corresponding, shoveling multi-stage oil cylinder is made stretching motion, is stretched out
When back door close in the case of promote shoveling rubbish extrude toward at carriage back door, original position is retracted to after the completion of compression, unloading
Stretch out during rubbish, by rubbish from compartment release, after the completion of retract.If it is back door on-off control machine that the operating valve connection of commutation is corresponding
Structure, then oil cylinder drive back door to be turned on and off, garbage-compressing or unloading are realized, while can locking at any time.
The advantage of this programme is：
1. because hydraulic oil is not big by load into partial discharge is fallen by stable point during pressure compensated flow control valve valve element
Little impact, the hydraulic oil into hydraulic jack is accordingly reduced, so as to operating mechanism's speed of service is steady, controllable, it is to avoid get rid of bucket；Together
When, effectively reduce the greater back-pressure produced than the Flow amplification that causes due to Multi-stage cylinder speed, efficiently solve " suppressing car " with
And the problems such as " hitting cylinder ".
2., due to arranging hydraulic lock, the course of work can stop at any time, and operating mechanism can long-time locking；When back door is closed
Locking more preferably, prevents the fluid seepage in rubbish, avoids stall to close after unlatching, and security incident occurs.
Beneficial effect
1st, flow, pressure distribution are reasonable, and energy-saving and emission-reduction, effectively solving is got rid of bucket, suppresses car, hits the phenomenons such as cylinder；
2nd, hydraulic lock is integrated on banked direction control valves, reduces the layout of pipeline, pipeline arrangement is more convenient, more attractive；
3rd, compact conformation, reliable operation, the simple laborsaving, oil circuit of manipulation switch accurate, easy for installation, easy to process, cost
It is cheap, easy to realize batch production.
