There is the spring groove 20 of L-shaped；
The inside of valve body 4 is provided with two projections 21, and two projections, 21, two dividing plates 15 form 4 oil pockets with rotating shaft 14, its
In 2 be high-voltage oil cavity a, 2 be low pressure oil pocket b, and the side face of valve body 12 is provided with 2 oil inlet c, and oil inlet c is through raised 21
Connect high-voltage oil cavity a；
Top end cover 7 is provided with torsion-bar spring 5, and torsion-bar spring 5 inserts the spring eye 19 of valve element 4, torsion bar through top end cover 7
The head of spring 5 is fixed by locking nut 6；
Fuel-displaced end cap 1 is provided with 2 oil-outs；
The tangential direction of valve body 12 is provided with bolt hole, and ball stud 10 is set in bolt hole, bullet is placed in the spring groove 20 of L-shaped
Spring 8, the outside of spring 8 set spring base 9, and the lateral surface of spring base 9 is arcwall face, and bulb and the arcwall face of ball stud 10 connect
Touch；The tangential direction of valve body 12 is provided with caging bolt 11, and caging bolt 11 stretches into the stroke limit groove 18 of valve element 4.
Torsion-bar spring 5 is with left hand thread.The oil outlet end 3 of valve element 4 is connected by sunk screw 2 with rotating shaft 14.
Operation principle of the present utility model and dynamic duty process, attachment structure, connected mode with reference to the technical program
And accompanying drawing is described：
First, as shown in Fig. 2,3,4,5, hydraulic oil enters 2 hydraulic oils from 2 oil inlet c of valve body 12 through projection 21
Chamber a, then by the damping hole 16 on the dividing plate 15 of valve element 4,2 low pressure oil pocket b are respectively flowed into, then pass through the fuel-displaced of valve element 4
2 oil-outs outflow of the oil outlet 17, fuel-displaced end cap 1 on 3 both sides is held, now oil outlet 17 overlaps with oil-out.
When the 2nd, if desired for the flow controlled is limited as Q：
1st, as shown in Fig. 6,7,8, the hydraulic oil that flow reaches Q enters valve inner high voltage oil pocket a, and hydraulic oil passes through valve element 4
Damping hole 16, according to expenditure and pressure principle, oil pressure will reduce, and the both sides of valve element 4 produce pressure difference dp, and low pressure oil pocket b oil pressure is less than
High-voltage oil cavity a oil pressure.It is noted that when if pressure difference dp reaches certain numerical value, caused moment of torsion will overcome spring 8, torsion bar bullet
The synthesis spring torque M of spring 5, valve element 4 rotate, and oil outlet 17 misplaces with oil-out, and final oil-out will close, stream
Amount Q is gradually decrease to 0, realizes disconnection hydraulic oil, is so achieved that and carries out the quantitative effect for limiting control to setting flow Q
Fruit.The stroke of valve element 4, determined by caging bolt 11 in the stroke of stroke limit groove 18.
2nd, when flow Q is decreased to 0, the pressure difference dp of the chamber of valve two will also be kept to 0, valve element 4 spring 8, torsion-bar spring 5 it is comprehensive
Close under spring-force driven dual, valve element 4 is rotated back into initial position, under the stop of caging bolt 11, valve element 4 returns to initial position i.e.
Stop motion, not reversible rotation.It can so ensure that the oil outlet 17 of valve element 4 is aligned again with oil-out, oil-out is beaten again
Open, flow Q gradually increases, and hydraulic oil starts again at circulation.
3rd, in fact, when flow Q increases to setting value, valve element 4 will start again rotation oil-out is turned down, back valve core
4 turn round again, i.e., pressure difference dp and spring 8, torsion-bar spring 5 synthesis spring torque M in the presence of constantly carry out back rotation, be in
One oscillatory process, the flow Q in valve is limited within certain relative stability range.
3rd, comprehensive spring torque M regulative mode (different flow Q corresponding equivalent to regulation) has three kinds：
1st, as shown in figure 9, adjustment ball stud 10 tightens degree, the deformation force of spring 8 is tightened with ball stud 10
And increase, valve element 4 needs to overcome the active force of spring 8 to increase when rotating, otherwise reduces.
Due to ball stud 10 and the special construction of spring base 9, spring base 9 is rotated, valve element 4 will not be made stuck.Adjust
Whole ball stud 10 can realize hydraulic fluid flow rate Q stepless changings within the specific limits.
2nd, unscrew locking nut 6, built-in length of the torsion-bar spring 5 in the spring eye 19 of valve element 4 is adjusted, when torsion-bar spring 5
When being entirely insertable in spring eye 19, now because the torsion bar length L to work is longer, according to the mechanics of materials, now torsion bar rigidity
Relatively low, deformation force is small.When torsion-bar spring 5 outwards bounces back, now because the torsion bar length L to work is shorter, according to the mechanics of materials,
The rigidity increase of torsion-bar spring 5, deformation force are big.
In the utility model, 2 sections of the design of torsion-bar spring 5 is divided to be merely illustrative, the utility model also can be as needed
It is designed to the torsion-bar spring of multisection type.
4th, especially, if not installing all back-moving springs (including spring 8 and torsion-bar spring 5), friction and liquid are being ignored
During bulk viscosity resistance, when flow Q very littles, correspond to pressure difference dp moments of torsion caused by inside and will be easy to rotational valve core 4, by oil-out
Close, due to no back-moving spring, by the flow that directly interruption is passed through, that is, realize the function of anti-leak in system.
Above-mentioned is the preferable embodiment of the utility model, but embodiment of the present utility model is not by the above
Limitation, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modification, replacement, combine, letter
Change, should be equivalent substitute mode, be included within the scope of protection of the utility model.
