Description
Technical field
The utility model relates to a kind of ceramic valve, particularly a kind of ceramic ball valve.
Background technique
The patent No. is that the Chinese patent of CN201110222440.8 discloses " a kind of ceramic ball valve ", by housing, valve rod, ceramic ball, left ceramic valve seat, right ceramic valve seat, body in pottery, ceramic flange liner, flange inner liner metal ring and positioning metal ring composition, the outer side surface of left ceramic valve seat and case inside face close contact, the inner side surface close contact of body in the outer side surface of right ceramic valve seat and pottery, the other end of body and the inside close contact of left ceramic valve seat in pottery, disc spring pressure ring is provided with between the right side facade of right ceramic valve seat and ceramic flange liner, between the right side facade of disc spring pressure ring and right ceramic valve seat, disc spring is installed.The shortcoming existed: 1 monolateral disc spring compensates the wearing and tearing of valve seat and spool, easily causes spool toward skew, causes spool and valve rod disalignment, is difficult to rotate, spool is turned broken.On the left of in the of 2, namely valve seat seals with middle body, again with seal spool, forms location, easily causes valve seat and middle body place to reveal, makes dielectric corrosion housing.
The patent No. is that the Chinese patent of CN200910111551.4 discloses " a kind of ceramic ball valve ", and it forms primarily of valve body, valve gap, valve ball, valve seat, set screw nut, swing arm and handle; Described valve seat has two, penetrates respectively and penetrate end to penetrate end formation spherical inner chamber mutually against, two valve seats from the cross through hole two ends of valve body; Described valve ball is spherical, and the spherical inner chamber Spielpassung that the spherical surface of valve ball and two valve seats are formed and valve ball can rotate in the horizontal direction at spherical inner chamber, makes the cross through hole of the cross through hole of valve ball and valve seat can be in through and close two states.The shortcoming existed: 1 when valve seat and valve ball have wearing and tearing, and valve seat and valve ball will be revealed, can not the wearing and tearing of auto-compensation valve seat and valve ball.2 when whole valve is toward Pipe installing, the valve seat of piping flange meeting squeeze valve, makes two valve seats toward middle mobile, holds valve ball tightly, easily make valve ball locking.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, provides a kind of ceramic ball valve that automatically can make up stem packing abradable seal and spheroid and prooving of valve seat auto-compensation.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of ceramic ball valve of the present utility model, it comprises the valve seat be arranged in middle body, there is the runner that fluid passes through in described valve seat, in described valve seat, spool is installed, the cross through hole of described spool and the runner of valve seat can be in through and close two states, in described valve seat is outer, the both sides of body are separately installed with flange, a valve rod is connected with spool by the hole on middle body, described valve rod is arranged in housing, be inlaid with flange liner respectively being positioned at the flange outside described valve seat, the valve seat of intersection inside the valve seat described in middle body two outside and flange is provided with groove step, between described groove step place's valve seat and flange, pad spring is installed, the inner end contacting point of flange and flange liner is provided with step, the inner end of flange liner and flange compress at the step place of flange and contact, between described valve rod and housing, therefrom be disposed with packing seal outside external side direction, pressure ring, disc spring, platen and limited ring, described platen is bolted on the platform in housing, body sealing ring and liner seal ring between middle body and valve seat and in being respectively arranged with between flange liner and valve seat.
Compared with prior art, the ball valve that the utility model provides has following beneficial effect:
1. valve seat is by the resiliently deformable close contact ball core of disc spring, and the contact of automatic regulating valve seat and ball core, the effect by disc spring after the prooving of valve seat is repaired automatically.And by the elastic strain of valve seat and disc spring, the moment of torsion that regulating spool rotates.
2. stem packing upper end has pressure ring to contact, there is biplate disc spring pressure ring upper end, disc spring there is platen, platen is bolted on shell deck. and valve rod passes through packing seal, along with valve rod rotates frequently, when filler mild wear, by the elastic strain of disc spring in this structure, the wearing and tearing of filler automatically can be repaired in time.
3. when the wearing and tearing of filler are larger, platen, lower than podium level, need not unload the driving mechanism on lower bolster, as long as screw the bolt of platen both sides, just can give the power that filler is downward, the wearing and tearing of filler are compensated.
4. flange liner directly and flange contact, contact with valve seat, and avoid valve body when being arranged on pipeline, pipe extrusion flange liner, is delivered to valve seat power, makes valve seat toward middle movement, locking spool.
5. stem packing automatic impaction, and filler pressure strip is hidden in below valve body platform, when stem wear is leaked, avoids the trouble of pretension stem packing again that final controlling element dismantled.
6., when spheroid and the prooving of valve seat, make valve seat toward middle mobile by the dish pad spring force restitution at valve seat step place, compensate the wearing and tearing of spheroid and valve seat, improve sealing.
