Portion is pressed into the top of valve body, and the upper half and lower half of the sleeve be fixed by bolt, the upper half of the sleeve with
The lower half of executing agency connects, and the upper half of the executing agency is connect with valve deck, and the sleeve is upper with valve rod junction
End and lower end are sealed by tetrafluoroethene fill block, and the lower spring end is mutually butted on sleeve, and upper end is mutually butted on spring base, described
It adjusts screw thread connection valve deck and lower end is connected to spring base, the lower half of the sleeve is equipped with the several of connection valve outlet
Pore, the inside of the executing agency be equipped with elastic piece, the fixed disk being installed on elastic piece, the elastic piece and fixed disk with
The displacement mechanism of the sleeve upper half is mutually fixed, and institute's displacement mechanism can be slided in the axial direction of sleeve, the valve rod
Upper end connects displacement mechanism, and lower end connects spool.
It is further preferred that the upper half of the executing agency is bolted with lower half.
It is further preferred that being equipped with gap between the corresponding valve interior wall of the pore and the lower half of sleeve.
It is further preferred that the quantity of the pore is two groups, and every group of pore is circumferentially uniformly distributed along sleeve.
It is further preferred that the lower end of the sleeve is connected and sealed by the valve seat of sealing bayonet and valve body.
The utility model has the beneficial effects that the micropressure adjusting valve structure is simple, and it is easy to install and use, it is set by multi-layer sealed
The sealing performance for improving regulating valve is set, and by unique sleeve and actuator design, so that the tune of micropressure adjusting valve
Section sensitivity is obviously improved, and improves the service life and using effect of regulating valve.

Specific embodiment
We do further a kind of Fluorine-lined operated micropressure adjusting valve described in the utility model in conjunction with attached drawing below
Explanation.
As shown in fig. 1, a kind of Fluorine-lined operated micropressure adjusting valve of the present embodiment, including valve body 1, valve rod 2, spool 3,
Sleeve 4, valve deck 5, executing agency 6, spring 7, spring base 8 and adjusting screw 9, the lower half of the sleeve 4 are pressed into the upper of valve body 1
The upper half in portion, the sleeve 4 is fixed with lower half by bolt 10, the upper half and the executing agency 6 of the sleeve 4
Lower half connection, the upper half of the executing agency 6 connect with valve deck 5, the upper end of the sleeve 4 and 2 junction of valve rod and under
End is sealed by tetrafluoroethene fill block 11, and 7 lower end of spring is mutually butted on sleeve 4, and upper end is mutually butted on spring base 8, described
It adjusts the threaded connection valve deck 5 of screw 9 and lower end is connected to spring base 8, the lower half of the sleeve 4 is equipped with connection valve body 1 and exports
Several pores 12, the inside of the executing agency 6 is equipped with elastic piece 61, the fixed disk 62 being installed on elastic piece, the bullet
Property piece 61 and fixed disk 62 and 41 phase of displacement mechanism of 4 upper half of sleeve are fixed, and institute's displacement mechanism 41 is in the axial direction side of sleeve 4
To that can be slided, the upper end of the valve rod 2 connects displacement mechanism 41, and lower end connects spool 3.The upper half of the executing agency 6
Portion and lower half are fixed by bolt 10.Gap is equipped between corresponding 1 inner wall of valve body of the pore 12 and the lower half of sleeve 4
42.The quantity of the pore 12 is two groups, and every group of pore 12 is circumferentially uniformly distributed along sleeve 4.The lower end of the sleeve 4 passes through
Sealing bayonet 43 and the valve seat of valve body 1 are connected and sealed.The working condition of the micropressure adjusting valve substantially under: when liquid is by valve body
Import to output flow when, a kind of upward thrust can be provided spool, so that spool and valve rod shift up, and spring pair
There is downward predetermined thrust in displacement mechanism, when spool and valve rod shift up, displacement mechanism can also move up compression bullet
Spring, so that spring is gradually increased the down thrust of displacement mechanism, until the upward thrust of liquid is equal to, spring is downward to be pushed away
Power adds architecture quality；Since the different liquids upwards thrust different in flow rate for spool is different, and by adjusting screw pair
Change the downward predetermined thrust of spring in the adjusting of spring initial compression degree, hence for different liquids, flow velocity according to specific
Flow demand is adjusted.By the cooperation of pore and elastic piece, fixed disk, the fine adjustment ability of regulating valve is improved, valve is avoided
Core is substantially displaced, and the fluctuation of regulating power is caused to change.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
