Purpose of the utility model is realized as follows: a kind of rotary linear flow control valve, including valve body and plunger,
It is provided with plunger hole in the middle part of the side of the valve body, the top of the plunger hole is respectively arranged with feed liquor along the two sides of valve body
Hole and fluid hole, are provided with deflector hole at the top of the valve body, the deflector hole respectively with inlet opening, plunger hole and fluid hole phase
Connection, the deflector hole and plunger hole junction are provided with the annular groove of certain angle, and the both ends of the plunger hole are respectively set
There is annular seal groove, plunger is provided in the plunger hole, a concave surface, the concave surface to column are provided in the middle part of the plunger
The center line distance of plug is 2mm, and the maximum distance between the width of the concave surface and two deflector holes is equal, the top of the valve body
Block is fixedly installed in the deflector hole in portion by welding, is provided with O-ring seal in the annular seal groove.
Further, the inlet opening is blind hole.
Further, the size and depth of the fluid hole are equal with inlet opening.
Further, the angle of the annular groove is 170 degree.
Further, the right end of the plunger is connected with servo motor.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
(1) matched by the concave surface of plunger being arranged with plunger hole, make hydraulic oil along inlet opening, deflector hole, annular groove,
Concave surface, annular groove, deflector hole, fluid hole flowing control the size of flow, reach flow since the concave surface of plunger can be rotated
To linear regulation, the speed of home lift is made to be effectively controlled；
(2) by the block and O-ring seal of setting, it ensure that hydraulic oil in the process of running, will not leak
The phenomenon that, guarantee the safety of operation；Meanwhile by the rotation of Serve Motor Control plunger, realizes the purpose accurately controlled, make to grasp
Make simpler.
Detailed description of the invention
Fig. 1 is the main view sectional view of the utility model.
Fig. 2 is the fragmentary cross-sectional view of the part 1 of the utility model.
Fig. 3 is the perspective view of the part 2 of the utility model.
In figure: 1, valve body 2, plunger 3, block 4, O-ring seal 101, plunger hole 102, inlet opening 103, out liquid
Hole 104, deflector hole 105, annular groove 106, annular seal groove 201, concave surface.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of rotary linear flow control valve, including valve body 1 and plunger 2, the valve body 1
Side in the middle part of be provided with plunger hole 101, the plunger hole 101 is through-hole, the top of the plunger hole 101, along the two of valve body 1
Side is respectively arranged with inlet opening 102 and fluid hole 103, and the inlet opening 102 is blind hole, and the fluid hole 103 is also blind hole,
The size and depth of the fluid hole 103 are equal with inlet opening 102, and the top of the valve body 1 is provided with deflector hole 104, described
Deflector hole 104 is connected with inlet opening 102, plunger hole 101 and fluid hole 103 respectively, the deflector hole 104 and plunger hole 101
Junction is provided with the annular groove 105 of certain angle, and the angle of the annular groove 105 is 170 degree, and the two of the plunger hole 101
End is respectively arranged with annular seal groove 106, plunger 2 is provided in the plunger hole 101, the middle part of the plunger 2 is provided with one
The center line distance of a concave surface 201, the concave surface 201 to plunger 2 is 2mm, so that concave surface 201 can have been realized with annular groove 105
Hermetically sealed, the maximum distance between the width of the concave surface 201 and two deflector holes 104 is equal, and the top of the valve body 1 is led
Block 3 is fixedly installed in discharge orifice 104 by welding, eliminates the gap due to processing technology bring valve body 1, is guaranteed
The sealing of valve body 1 is provided with O-ring seal 4 in the annular seal groove 106.
The right end of the plunger 2 is connected with servo motor, so that the rotation of plunger 2 is precisely controlled, realizes hydraulic
The Linear Control of flow.
When the utility model is used, firstly, driving plunger 2 to be rotated when elevator starting by servo motor, making
Obtaining concave surface 201, there are certain gaps with annular groove 105, to realize the flowing of hydraulic oil, reach the starting of elevator；Then,
With the rotation of servo motor, when gap is increasing to a certain amount of, elevator is by accelerating starting to even running at this time；Finally,
When with elevator close to destination, with the rotation of servo motor, gap starts to become smaller again, and elevator is become by even running at this time
To run slowly, until gap is closed completely, at this time without hydraulic oil process, elevator stops；During whole service, due to block
3 and O-ring seal 4 presence, ensure that hydraulic oil will not leak, simultaneously as the component of the utility model is less, system
Stability it is stronger, operation is also simpler.
