Description
Technical field
The utility model is related to a kind of valve more particularly to a kind of valves with two-way sealing ring.
Background technology
The sleeve of sleeve-type regulating valve is clearance fit with flap, and multiple throttling windows, the shape of window are provided on sleeve
Determine that the discharge characteristic of regulating valve, the size of window influence the flow coefficient Cv of regulating valve.Valve seat use from centering without
The snap-in structure of screw thread, the conical seal surface on valve seat match to form cut-out sealing pair with the conical seal surface on flap, protect
Valve tightly turns off when card flap is pressed on valve seat.The size of valve-seat diameter influences the flow coefficient Cv of regulating valve.On flap
Be parallel to it is axial have symmetrical balance hole, make the chamber of flap upper and lower end face, medium acts on flap in such valve
Power in axial direction is largely cancelled out each other, and the out-of-balance force that medium generates on valve rod is just very small.
Sleeve-type regulating valve in the prior art cannot achieve two-way sealing, to affect whole sealing effect.
Utility model content
The utility model discloses a kind of valves with two-way sealing ring, to solve the spool of valve in the prior art
The problem of cannot achieve two way seal between sleeve.
The above-mentioned purpose of the utility model is achieved through the following technical solutions：
A kind of valve with two-way sealing ring, including：Sleeve is installed in one valve seat, a valve is installed in the sleeve
Core, wherein be equipped with annular recess between the sleeve and the spool, sealing ring, two way seal are equipped in the annular recess
Ring, the two-way sealing ring upper surface, lower surface all have c-opening, the annular recess lower wall, sealing ring downside
The equal Matching installation of wall has annular projection；The annular projection is embedded in the c-opening.
Valve as described above with two-way sealing ring, wherein an annular recess is equipped in the annular recess, it is described
There is sealing ring one and the matched seal convexity of the annular recess, the seal convexity to be embedded in the annular recess.
Valve as described above with two-way sealing ring, wherein the annular recess is opened in the spool upper surface
Between side wall；The sealing ring upper surface is directly facing the valve seat.
Valve as described above with two-way sealing ring, wherein the valve seat has two side-entrances.
Valve as described above with two-way sealing ring, wherein the annular projection is mounted on described by fixed ring
In sealing ring lower wall, the annular recess lower wall.
Valve as described above with two-way sealing ring, wherein there is spring structure in the c-opening.
In conclusion by adopting the above-described technical solution, the utility model solves the spool of valve in the prior art
The problem of cannot achieve two way seal between sleeve by the way that the two-way two-way sealing ring with c-opening is arranged, and coordinates close
Seal ring together, realizes excellent sealing two-way between spool and sleeve.
Description of the drawings
Fig. 1 is the schematic structural cross-sectional view for the valve that the utility model has two-way sealing ring；
Fig. 2 is the enlarged diagram of the sealing structure for the valve that the utility model has two-way sealing ring.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples：
Fig. 1 is the schematic structural cross-sectional view for the valve that the utility model has two-way sealing ring,
Fig. 2 is the close-up schematic view for the valve that the utility model has two-way sealing ring, refers to Fig. 1, Fig. 2, one
Valve of the kind with two-way sealing ring sealing ring 5, including：Sleeve 7 is installed in one valve seat 9, a spool 4 is installed in sleeve 7,
Wherein, it is equipped with annular recess between sleeve 7 and spool 4, sealing ring 6, two-way sealing ring sealing ring 5 are equipped in annular recess, it is close
Seal ring 6, two-way sealing ring sealing ring 5 collectively constitute a sealing structure 2, and 6 upper surface of two-way sealing ring, lower surface all have c-type
Opening, annular recess lower wall, the equal Matching installation of 6 lower wall of sealing ring have annular projection；Annular projection is embedded in c-opening.
Further, an annular recess is equipped in annular recess, sealing ring 6 is convex with the matched sealing of annular recess with one
It rises, seal convexity is embedded in annular recess.
Further, annular recess is opened between 4 upper surface of spool and side wall；6 upper surface of sealing ring is directly facing valve
Seat 9.
Further, valve seat 9 has two side-entrances.
Further, annular projection is mounted on 6 lower wall of sealing ring, in annular recess lower wall by fixed ring.
Further, there can be spring structure in the c-opening of the utility model.Can be elastic piece, so as to
Preferably coordinate with annular projection.
Specifically, during implementing the utility model, since the two-way C-spring accumulation of energy with back-to-back form is close
The namely two-way sealing ring sealing ring 5 of seal ring 6 solves the problems, such as bidirectional fluid high pressure self-tightening, and increases using in two opening directions
The method of sealing ring 6 has been added to play the role of supporting sealing two-way seal ring seal ring 5.After spool 4 is closed, when fluid is from valve
After left side runner enters, the lower c-shaped opening of two-way C-spring accumulation of energy sealing ring 6 is flowed upwardly into, lower c-shaped opening sealing lip is applied
Plus-pressure, with the raising of system pressure, sealing starts to expand so that total sealed pressure increases, and reaches on the left of tight seal
The effect of fluid；After side enters fluid on the right side of the valve, 7 epicoele of sleeve is flowed upwardly into through the balance hole on spool 4, then to
The lower upper c-shaped opening for flowing into two-way C-spring accumulation of energy sealing ring 6 applies pressure to lower c-shaped opening sealing lip (sealing ring 6), with
The raising of system pressure, sealing starts to expand so that total sealed pressure increases, and reaches the effect of fluid on the right side of tight seal
Fruit.
