Specific embodiment
Fig. 1 is the most preferred embodiment of the utility model, and 1 ~ 5 pair of the utility model is described further with reference to the accompanying drawing.
Embodiment 1:
As shown in Figure 1, a kind of multistage flowing speed type throttle valve (hereinafter referred to as orifice valve), including valve body 6, valve body 6 be
Cylindrical shape is internally provided with the inner cavity axially penetrated through in valve body 6, and in valve body 6, wherein one end is open end, the port of the other end
Place's setting is equipped with end cap 7 and forms closed end, and several normal open holes 8 are offered on end cap 7, and it is outer for defining 6 open end side of valve body
Side, 7 side of end cap are inside.
The spool 3 axially penetrated through is provided in the inner cavity of valve body 6,3 one end of spool is fixed at the center of end cap 7, separately
One end extends at the port of 6 other side of valve body.Two panels valve block 2 is disposed with from inside to outside in the lumen, in two panels valve block 2
Between and inner end valve block 2 and end cap 7 between be respectively arranged with a spring 5, wherein the bullet of outside (close to open end) spring 5
Property coefficient is less than the coefficient of elasticity of interior lateral spring 5.Two panels valve block 2 and two springs 5 are sleeved on the outer ring of spool 3 simultaneously, lead to
Setting spool 3 is crossed, in order to sliding axially along valve body 6 in 2 inner cavity of valve block.
The outside of valve body 6 is provided with screw 1, screw 1 screws in spool 3, and six side of fastening of end keeps off in valve block 2
Outside prevents valve block 2 from popping up at the port of valve body 6 under the elastic force of spring 5, and valve block 2 is under the position-limiting action of screw 1 outside it
End face is located at the port of valve body 6.
Offer flowing hole 4 respectively on two panels valve block 2, flowing hole 4 is arbitrary shape.Overcurrent on adjacent two panels valve block 2
The projection section of the position in 3 axial direction of spool that open up in hole 4 is overlapped, therefore two panels valve block 2 is after fitting, the adjacent valve block of two panels
Flowing hole 4 on 2 can shade one another.Simultaneously inner terminal valve block 2 flowing hole 4 open up position with normal open hole 8 opening on end cap 7
If projection section of the position in 3 axial direction of spool is overlapped.The flowing hole 4 being arranged on each valve block 2 can be different by setting
Shape and realize coincidence, can also by be arranged different size realize coincidence.
Opened up at least one contact surface (two valve blocks 2 or valve block 2 and end cap 7) of 5 two sides of spring it is fluted, with guarantee
Spring 5 can be integrally placed in groove after being compressed, so that ensure that can be tight between two valve blocks 2 or valve block 2 and end cap 7
Closely connected conjunction.
Specific work process and working principle are as follows:
This orifice valve is mounted in hydraulic oil pipeline, and the inner sealing of the outer wall of valve body 6 and hydraulic oil pipeline is arranged, by
In being provided with normal open hole 8 on end cap 7, thus normal open hole 8 cooperatively formed with the flowing hole 4 on valve block 2 it is hydraulic in this orifice valve
The circulation passage of oil.When hydraulic oil flows decrease in hydraulic oil pipeline, hydraulic oil flows through orifice valve by circulation passage.
When the flow velocity of the hydraulic oil of hydraulic oil pipeline mutates, hydraulic oil is applied to the oil pressure on valve block 2 can be unexpected
Become larger, when the pressure of hydraulic oil is enough to overcome the elastic force of outermost end spring 5, the valve block 2 of outermost end can be pressed towards the interior of valve body 6
Portion, and be gradually bonded with second valve block 2 on the inside of it, since the flowing hole 4 on two panels valve block 2 only partially overlaps,
After being bonded to each other, the flowing hole 4 on two panels valve block 2 can be blocked mutually two panels valve block 2, therefore reduce the stream of circulation passage
Logical area, therefore the velocity of liquid assets of hydraulic oil is slowed down, realize first segment speed regulation.
When the pressure that the flow velocity of hydraulic oil continues to change and formed is enough to overcome the elastic force of second spring 5, two plate valves
Piece 2 can be mobile to the inner end of valve body 6 by hydraulic action simultaneously, until be bonded with end cap 7, the meeting of flowing hole 4 at this time further by
It blocks, since flowing hole 4 and the normal open hole 8 of inner terminal valve block 2 partially overlap, this orifice valve is in minimum circulating face at this time
The area of long-pending circulation status, the circulation passage of hydraulic oil is in minimum, realizes second segment speed regulation, realizes restriction effect, when
When the pressure of hydraulic oil is gradually reduced, valve block 2 can gradually reset under the action of spring 5, to realize the control of flow.
Embodiment 2:
As shown in Fig. 2, the present embodiment the difference from embodiment 1 is that: eliminate the spool 3 being applied in inside valve body 6, by
In offering the groove that can accommodate spring 5 on valve block 2 or/and end cap 7, therefore spring 5 is not in radial displacement.
The open end uniform intervals of valve body 6 are provided with muti-piece baffle 9, baffle 9 prevents valve block 2 to be ejected playing
Flowing hole 4 will not be blocked while effect, while valve block 2 will not be impacted to obstruction hydraulic oil.
The course of work and working principle of the present embodiment are same as Example 1, and details are not described herein.
Embodiment 3:
As shown in figure 3, the present embodiment the difference from embodiment 1 is that: a piece of valve block 2, valve block are only provided in valve body 6
A spring 5 is provided between 2 and end cap 7, the flowing hole 4 of valve block 2 opens up position and normal open hole 8 opens up position on end cap 7
The projection section set in 3 axial direction of spool is overlapped, therefore realizes hydraulic oil two-stage stream by one section of speed regulation in the present embodiment
The switching of speed.
The course of work and working principle of the present embodiment are same as Example 1, and details are not described herein.
Embodiment 4:
As shown in figure 4, the present embodiment the difference from embodiment 1 is that: outermost valve block 2 and spool 3 are coaxial fixed, valve
Core 3 is passed through rear from the center of remaining valve block 2 while being pierced by from the center of end cap 7, band after outermost valve block 2 is pressurized movement
Movable valve plug 3 is mobile simultaneously.
Embodiment 5:
As shown in figure 5, the present embodiment the difference from embodiment 1 is that: in the present embodiment, on the medial surface of end cap 7
It is vertically installed with a plurality of throttling pillar 10 different in size, the position for opening up position and being overlapped with the flowing hole 4 on valve block 2 of throttling pillar 10
It sets corresponding.When valve block 2 is by hydraulic move inward, throttling pillar 10 sequentially enters valve block 2 according to sequence from long to short
In flowing hole 4, the fluid area of hydraulic oil circulation passage is further reduced.
Embodiment 6:
The present embodiment the difference from embodiment 1 is that: be internally provided with greater number of valve block 2 in valve body 6, and adjacent
Projection section of the position in 3 axial direction of spool that open up of flowing hole 4 is overlapped on two panels valve block 2, while the overcurrent of inner terminal valve block 2
Hole 4 opens up position and is overlapped with open up position projection section on spool 3 axial direction of the normal open hole 8 on end cap 7, it is achieved that
The adjusting of hydraulic oil more multistage flow velocity.
This multistage flowing speed type throttle valve can make any combination of above embodiments.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
