Bar 6 and drive link 7, valve deck are arranged on valve body 5, and valve pocket 1 is built in valve body 5, and what spool 2 moved up and down is built in valve pocket 1
Inner cavity in, valve rod 6 rotate setting on valve body 5, the top of drive link 7 is threadedly coupled with valve rod 6, and axis is provided on valve deck
To rotary spacing hole, the end of drive link 7 is fed through axial rotation limit hole and is fixedly connected with spool 2, and spool 2 has cylinder
The bottom of outer wall, valve pocket 1 extends to the entrance 8 of valve body 5, and positive round metering orifice 3 is offered on valve pocket 1.
By being provided with positive round metering orifice 3 on valve pocket 1, valve opens when the hole of such special construction can be such that spool 2 moves
Open area is linear.Achieve the purpose that linear regulation controls rate-of flow, so that spool 2 is moved in opposite valve seat to realize
When, the opening area of valve linearly increases with the displacement distance of spool 2.As shown in Figure 3, wherein X-axis is spool 2
Displacement distance, Y-axis include the opening area of valve and the flow of medium, and the corresponding curve of alphabetical Q indicates the flow of medium, letter
The corresponding curves of A represent the opening area of valve.
Wherein, it is provided with first annular boss on spool, the second annular convex platform is provided on valve pocket, first annular boss
Lower section is provided with sealing ring, when spool is closed valve body, sealing ring and the second annular convex platform gluing, sealing.
In actual use, it is not in fact between spool 2 and valve pocket 1 due to working as (any Lift) after valve opening
It needs to seal, therefore, by the way that first annular boss is arranged on spool 2, the second annular convex platform, the first ring is set on valve pocket 1
Sealing ring is arranged in the lower section of shape boss, when spool 2 is closed valve body, sealing ring and the second annular convex platform gluing, sealing, and work as
After valve opening, its sealing function is also lost at the sealing therewith, to agree with when the valve opening after, spool 2 and valve pocket 1 it
Between be the case where need not sealing.It the characteristics of ingenious valve actual use operating mode combined, i.e., to be sealed when valve is closed, valve
Door open when should not sealing function, greatly make simplifying the structure for valve, valve pocket most surfaces that need not all finish, from
And sealing structure is simplified, it reduces the production cost.
In order to advanced optimize said program, 3 outside of positive round metering orifice is coated with filter screen 4, and filter screen 4 is annular filter
Net is set on valve pocket 1.By being arranged metal filter screen in the outside of valve pocket 1, further filtration system medium, filter screen 4 can be with
According to system filtering accuracy free switching, terminal device is protected.Also, when medium again by this few aperture on strainer 4 when
Time would not send out noise, i.e., ear-piercing medium streaming voice solves the problems, such as that industry inner valve will produce noise.
Specifically, positive round metering orifice 3 is four, and uniformly it is circumferentially positioned on the outer wall of valve pocket 1, four positive round metering orifices
3 have interval between the internal chamber wall of valve body 5 so that medium can flow.3 face valve body 5 of one of positive round metering orifice
Outlet and the two concentric be arranged.
Wherein, the boss extended towards the cavity inside valve body 5 is provided on valve deck, the end set of boss has hexagonal
Hole, hexagon ring are axial rotation limit hole, and the outer wall of drive link 7 is the hexagon coordinated with hexagon ring.The end of drive link 7 with
Spool 2 is fixedly connected.
In order to advanced optimize said program, the bottom of spool 2 is plane, reduces the resistance to medium.The bottom of valve pocket 1
It is provided with sealing device between the entrance of valve body 5.Specifically, sealing device is hard sealing.Sealing device can be annular
Gasket.
In order to advanced optimize said program, drive link 7 is internally provided with cavity, and the end of drive link 7 offers
