Description
Technical field
The present invention relates to mine paste body filling technical field, more particularly to a kind of non-return valve assembly, and one kind are provided with this
The pumping filling pipeline system of non-return valve assembly.
Background technology
Paste body filling is exactly that the solid waste such as the mine tailing in mine, rubble, flyash, industrial slags are fabricated to be not required to take off
The paste slurry of water, by pump pressure or Action of Gravity Field, by pipeline to underground filling region.In Paste-filling System,
5 subsystems, the respectively dense system of tailing slurry, aggregate crushing and screening system can be typically divided into according to filling process flow
System, filling slurry stirring preparation system, pumping filling pipeline system, electric control system etc..
In Paste-filling System, some Filling Stations are built in below stowboard position, and the arrangement of filling pipeline must be
Edge ramps up arrangement.So the filling slurry in high position in the presence of self gravitation, can produce downwards in filling pipeline
Raw great pressure.This discrepancy in elevation has tens meters, or even hundreds of meters, and caused pressure is up to 10MPa or so.
In the prior art, the conveying power of filling slurry fills industrial pumping source source not by S valve-type piston type in filling pipeline
It is disconnected to provide.
Refer to Fig. 1 and Fig. 2, it is known that, the basic functional principle of S valve-type piston type filling industrial pump pumping filling slurry

Slurry in cylinder enters in filling pipeline under the promotion of piston 4 through S pipes 3 and discharging opening 2；After the completion of one stroke, S pipes 3 are put
To another concrete cylinder 5 (that concrete cylinder 5 of suction out of hopper 1 before i.e.), the piston 4 in the cylinder carries out next
Filling motion.In this way, swung by S pipes 2, the motion of the reciprocating of 5 inner carrier of concrete cylinder 4, to realize filling slurry source
Source constantly pumps.The swing power resources of S pipes 3 are driven in the hydraulic power system being connected with S valve-type piston type filling industrial pump
The active force of dynamic oscillating oil cylinder 6.
The shortcomings that above-mentioned S valve-type piston type filling industrial pump, is, when S pipes 3 go to another coagulation from a concrete cylinder 5
During olla 5 (general time-consuming 2 seconds or so), due to the work of the inner carrier 4 of concrete cylinder 5 when the position of S pipes 3 and concrete cylinder 5 is staggered
Blow-by between chock plug and S pipes 3, so as to cause to pump a small amount of pressure release in filling pipeline system, the slurry filled in filling pipeline
It will flow backwards, S valve-type piston type filling industrial pump is impacted, influences working efficiency.If pumped to high position, it influences

Chamber, the valve element 132 of non-return valve assembly is driven to move up and down, so as to control being turned on and off for non-return valve assembly.
In a particular embodiment, it is contemplated that non-return valve assembly need to be acted with S pipes synchronous coordination and pressure rating is identical, swings
By the fuel feeding of S valve oils pump 9, S valve oils pump 9 is that discharge capacity is 45ml/r constant pressure pumps for oil cylinder 6 and valve body oil cylinder 131.Also, pass through parallel connection
Two accumulators 8 set provide hydraulic oil for oscillating oil cylinder 6 and valve body oil cylinder 131.
Fig. 6 specifically is referred to, is that non-return valve assembly fills the hydraulic schematic diagram after industrial pump group is closed with S valve-type piston type.
It follows that the swing power resources of S pipes 3, in S valve oils pump 9, the hydraulic oil that S valve oils pump 9 provides is through relevant control
Valve group enters the second electromagnetic switch valve group 7, obtains electric or dead electricity through the second electromagnetic switch valve group 7, enters pressure oil and swing oil
Cylinder 6 (left swing valve oil cylinder or right pendulum valve oil cylinder), to promote S pipes to swing, in oil circuit the effect of two accumulators 8 in parallel be for
Ensure that S pipes 3 swing the high thrust of required moment, so as to ensure that it is quick strong that S pipes 3 commutate.
Also, design (electric i.e. with second from 2 positions of A, B in the hydraulic system of S valve-type piston type filling industrial pump
Magnetic commutation valve group 7 position in parallel) connected pipes, hydraulic oil enters solenoid valve group after the first electromagnetic switch valve group 12
134, the rod chamber and rodless cavity of the valve body oil cylinder 131 entered back into check-valves totality, so as to provide high pressure for valve body oil cylinder 131
Oil, to drive the valve element 132 in non-return valve assembly and the coordinated movement of various economic factors of S pipes 3.
Valve element when in the specific implementation, to ensure the swing of S pipes 3 and the switch coordination of valve element 132, the i.e. swing of S pipes 3
132 make valve body close, and when S pipes 3 swing stopping, valve element 132 makes valve body open-minded, must just control two electromagnetic switch valve groups
(the second electromagnetic switch valve group 7 and the first electromagnetic switch valve group 12) upper 4 electromagnet obtain the electric and logical relation of dead electricity.Its
In, the second electromagnetic switch valve group 7 and the first electromagnetic switch valve group 12 are made up of two three position four-way directional control valves respectively.
From schematic diagram as can be seen that the first electromagnet DT1 or the second electromagnet DT2 are powered, S pipes are begun to the left or to the right
Mobile, now the 3rd electromagnet DT3, which is just obtained, must obtain electric signal, obtain the 3rd electromagnet DT3 electric, the 4th electromagnet DT4 dead electricity,
Now valve element makes valve body close, and prevents that slurry flows backwards in filling pipeline.After S pipes are swung in place, telecommunications is fed back using proximity switch
Number obtain the 4th electromagnet DT4 electric, the 3rd electromagnet DT3 dead electricity, valve element makes valve body open-minded, and slurry enters filling pipe by S pipes
In road.4 electromagnet by turns dead electricity and it is electric, S pipe cyclically swing, valve element constantly makes valve body open or close, from
And play a part of non-return so that slurry endlessly conveys in filling pipeline to a high position.
In addition, in pumping filling pipeline system provided in an embodiment of the present invention, for the oscillating oil cylinder 6 for controlling S pipes to swing
The Selection and Design again that relevant portion is done in the hydraulic system of action, including：
Because S valve oils pump 9 will be simultaneously to oscillating oil cylinder 6 and the fuel feeding of valve body oil cylinder 134, the constant pressure pump selected in the prior art
Discharge capacity is too small, and it is 28ml/r that the discharge capacity used originally is substituted with the constant pressure pump that discharge capacity is 45ml/r (A10V045DKO1)
(A10V028DKO1) constant pressure pump；
It is oscillating oil cylinder 6 and valve body in the accumulator 8 of a same specification in parallel again on installation accumulator 8 position originally
The commutation of oil cylinder 134 provides the hydraulic oil of big flow, quick strong so as to ensure to commutate and lift；
Because S valve oils pump 9 increases, correlation conveying oil pipe specification re-starts design, is allowed to and system matches.
By above-mentioned design and repacking, non-return valve assembly provided in an embodiment of the present invention and pumping filling pipeline system,
Used in the Paste-filling System to high-order pumping slurry, verified under conditions of actual condition, running situation is good, serves
Non-return acts on, and has reached purpose of design.
