Working principle: a kind of three-way diverter valve with accumulation of energy valve seat, slurry shield machine pipe connector trolley are equipped with straight-through change
To valve and reversal valve is blocked, lead directly to reversal valve and blocks the structure that reversal valve is three-way diverter valve of the present invention.
Straight-through reversal valve and closure reversal valve include valve body 1 and are located at the intracorporal spool 2 of valve, lead directly to the interface of reversal valve
It is responsible for respectively with slurry shield machine mudaIt is responsible for mudbConnection, block the interface of reversal valve respectively with the mud of slurry shield machine
Slurry supervisoraIt is connected to mud blocking pipe.Interface is arranged on valve body 1, and arced flow path 7 is equipped in spool 2, and spool 2 rotates
Realize 7 selectivity connection two of them interface of runner.Three-way diverter valve of the present invention uses hydraulic-driven, and hydraulic cylinder drives gear teeth
Item drives spool 2 to rotate, and spool 2 is equipped with runner 7, and there are three interfaces on valve body 1 can switch runner as spool 2 rotates
7 communication path.
Mud is responsible for when three-way diverter valve worksaIt is responsible for mudbConnection, mud are responsible for by spool runner 7 and mud
There are leakage problems when interface connection connects so 1 inner wall of valve body inlet and outlet channel side is equipped with accumulation of energy valve seat 3 along pipeline
1 inner wall surrounding pipe joint one of valve body at mouth 20mm encloses, and has two seals annulus in 3 structure of accumulation of energy valve seat, seal band
Inside and outside have several curved tablets 4, curved tablet 4 can be such that rubber layer is fitted tightly on 1 inner wall of valve body, curved tablet 4
Accumulation of energy valve seat 3 is fixed in valve body 1 by sunk screw 5, sunk screw 5 is completely embedded into curved tablet 4 and can prevent and spool 2
Contact, seal band is internally hollow structure, wherein placing accumulation of energy canted coil spring 6, is used as rubber layer by accumulation of energy canted coil spring 6
Support construction.
Spool 2 and accumulation of energy valve seat 3 form sealing cooperation, and spool and seal band mutual extrusion form sealing structure, prevent
Fluid leakage, it is ensured that the fluid in spool runner 7 will not be flowed out by the gap between valve body 1 and spool 2, it is ensured that spool stream
Leakproofness, accuracy when the switching connecting pipeline of road 7.When spool 2 is motionless, spool 2 brings valve seat 3 constant pressure, makes three
Logical reversal valve is in sealing state, and when gear band movable valve plug 2 rotates, the rotation of spool 2 changes 3 stress condition of valve seat,
Not only compression power acts on for it, also by with pressure perpendicular and with the consistent frictional force of 2 rotation direction of spool, at this time accumulation of energy canted coil spring
6 mechanical property reduces 2 rotary resistance of spool, and three-way diverter valve is still in sealing state.
Since triplet commutation valve body 1 and 2 spacing of spool are fixed, sealing performance is mainly by 3 elastic property of accumulation of energy valve seat
It determines, to select satisfactory spring according to pressure requirements and checking its sealing effect, the present invention is also in accumulation of energy valve seat
6 parameter relationship formula of accumulation of energy canted coil spring is derived:
The first step, the stress of accumulation of energy canted coil spring 6 and deformation process are complex, when spring stress, with
The variation of displacement, the structure of spring are also changing, and change so as to cause the whole stress condition of spring, so this is specially
Benefit is calculated spring deflection by simplified model and derives spring rate formula.
Power suffered by accumulation of energy canted coil spring 6 is radial force, and structure has symmetry, and the shape of each individual pen is identical, together
When accumulation of energy 6 contacts of canted coil spring it is uniform, so the stress of each individual pen is consistent with deformation, bullet can be tiltedly enclosed into accumulation of energy
The radial force situation of spring 6 is simplified to the stress condition of individual pen accumulation of energy canted coil spring.
Second step, since deformation stored in elastomer can be related with external force and the final numerical value of displacement, and with add
Load mode is unrelated, so carry out the derivation of equation using Mohr's theorem, if it is desired to the displacement of the lines of certain point, only need at that point along
The direction of displacement of the lines acts on a unit concentrated force, calculates spring deflection with this.
To simplify the calculation, it is also necessary to carry out certain it is assumed that set its oval cross section long axis a length ofa, short axle is a length ofb, line footpath
Ford, load of the rod end bearing by vertical directionF,I x It is pairxThe moment of inertia of axis,I y It is pairyThe moment of inertia of axis.
Third step, 6 stiffness relation formula of accumulation of energy canted coil spring:
In formula:kIt is the rigidity of annular accumulation of energy canted coil spring,N/mm；FThe power that spring is born,N；∆lIt is the deformation of spring
Amount,mm；EIt is elasticity modulus,MPa； nIt is number of coils；μIt is material Poisson's ratio.
6 tilt angle calculation formula of accumulation of energy canted coil spring:
In formula:cIt is single-coil spring both ends spacing,mm。
6 pitch calculation formula of accumulation of energy canted coil spring:
In formula:DIt is the diameter of ring spring,mm。
After spring bears radial load, long axisaIncrease, short axlebShorten, divides according to gained spring rate relational expression is derived
Analysis, rigiditykAs the variation of major and minor axis is in non-linear increase tendency, so accumulation of energy valve seat 3 of the present invention chooses accumulation of energy and tiltedly encloses bullet
Accumulation of energy canted coil spring 6 is still in elastic limit when valve is in sealing state and maximum load when need to determine minimum load when spring 6.
In conclusion the three-way diverter valve with accumulation of energy valve seat, squeezes valve seat by three-way change-over valve core and forms sealing,
But long-term work spool will appear with valve seat to be seriously worn, and this patent devises a kind of three-way diverter valve with accumulation of energy valve seat,
Accumulation of energy valve seat 3 is elastic construction and selects elastic material, reduces frictional force and shearing force suffered when valve core rotation, and accumulation of energy
Accumulation of energy canted coil spring 6 inside valve seat 3 has good resilience performance, and spool 2 and accumulation of energy valve seat 3 squeeze for a long time when avoiding sealing
Caused great horizontal stress reduces the size of the torque of valve rod rotation process generation and the abrasion to spool 2, extends valve
Door service life.
The three-way diverter valve with accumulation of energy valve seat is able to bear certain compressive deformation by accumulation of energy canted coil spring 6, reduces
The deflection of spring, and can utmostly compensate uneven surface and tolerance bring is combined to influence, so that accumulation of energy valve seat 3 is being shaken
It is worked normally under the severe engineering specifications such as dynamic, impact.
