The utility model relates to a kind of locking elastic metallic sealing orbit ball valve, and this orbit ball valve comprises valve body, spheroid, valve seat, guide finger, valve rod, valve gap, directional post, rolling bearing, Stem Mut, handwheel, protecting jacket, indicating arm, Bearing housing and chain lock.Described valve body is upper dress formula structure, described valve seat is elastic seat, can micro-deformation, sealing force under various operating modes is compensated, guarantee that sealing is reliable, described handwheel is spoke handwheel, and described Bearing housing is provided with band chain orifice plate, chain lock, by handwheel spoke with the chain hole on chain orifice plate, can lock handwheel.The utility model adopts dress formula structure, can on-line maintenance, reduce parking machine meeting, and operate moment of torsion little, valve easily opens and closes; Adopt elastic seat, applicable various operating modes and sealability are reliable; On bearing gland, increasing a chain orifice plate, can install locking device additional, is misoperation thereby avoid people, and safety coefficient is high.
Description
Technical field
The utility model relates to valve technology field, specifically relates to a kind of locking elastic metallic sealing orbit ball valve.
Background technique
The structure of the common rail ball valve of prior art is mainly comprised of valve body, valve gap, spheroid, common single valve seat, valve rod, guide finger, directional post, rolling bearing, Stem Mut, handwheel, protecting jacket (cap) and switch indicator etc., the shortcoming of this structure is mainly manifested in two aspects: 1, under harsh operating mode, due to high temperature or High Pressure, spheroid is pressed on valve seat, produce very large active force, common valve seat can not produce distortion, easily cause even distortion of sealing pair damage, affect life of valve; 2, orbit ball valve is used on pipeline mostly, and pipeline is usually distributed in the place of field unattended, due to handwheel light switch valve just, easily by people's misoperation.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, and a kind of locking elastic metallic sealing orbit ball valve is provided.This orbit ball valve comprises valve body, spheroid, valve seat, guide finger, valve rod, valve gap, directional post, rolling bearing, Stem Mut, handwheel, protecting jacket, indicating arm, Bearing housing and chain lock.Described valve body is upper dress formula structure, described valve seat is elastic seat, can micro-deformation, sealing force under various operating modes is compensated, guarantee that sealing is reliable, described handwheel is spoke handwheel, described Bearing housing is arranged on valve gap, described Bearing housing is provided with band chain orifice plate, and chain lock, by handwheel spoke with the chain hole on chain orifice plate, can lock handwheel.
During unlatching, thereby by handwheel, driving Stem Mut to rotate band ovable valve stem rises, spheroid and elastic seat are departed from, and when directional post enters valve rod spiral chute, valve rod rotates and rises, the rotation of drive spheroid, until valve opening, chain lock is through handwheel spoke with the chain hole on chain orifice plate, with locking, handwheel can not rotate, and valve can not be closed; While closing, thereby by handwheel, drive Stem Mut to rotate with ovable valve stem under the effect of directional post, rotate and decline, drive spheroid rotation, until directional post is while entering the straight trough of valve rod, valve rod declines, and the wedge pressure by valve rod compresses spheroid and elastic seat seal, valve closing, chain lock is through handwheel spoke with the chain hole on chain orifice plate, with lock, lock, handwheel can not rotate, and valve can not be opened.
The utility model beneficial effect is compared with prior art: dress formula structure in employing, can on-line maintenance, and reduce parking machine meeting, operate moment of torsion little, valve easily opens and closes; Adopt elastic seat, applicable various operating modes and sealability are reliable; Adopting bearing gland, and be provided with a chain orifice plate thereon, can install locking device additional, is misoperation thereby avoid people, and safety coefficient is high.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Description of reference numerals: 1 is valve body, 2 is spheroid, and 3 is elastic seat, and 4 is guide finger, and 5 is valve rod; 6 is valve gap, and 7 is directional post, and 8 is rolling bearing, and 9 is Stem Mut; 10 is handwheel, and 11 is protecting jacket (cap), and 12 is indicating arm, and 13 is that Bearing housing, 14 is chain lock.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1; above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of locking elastic metallic sealing orbit ball valve, this orbit ball valve comprises valve body 1, spheroid 2, valve seat 3, guide finger 4, valve rod 5, valve gap 6, directional post 7, rolling bearing 8, Stem Mut 9, handwheel 10, protecting jacket 11, indicating arm 12, Bearing housing 13 and chain lock 14.Valve body 1 is upper dress formula structure, valve seat 3 is elastic seat, can micro-deformation, sealing force under various operating modes is compensated, guarantee that sealing is reliable, handwheel 10 is spoke handwheel, Bearing housing 13 is arranged on valve gap 6, Bearing housing 13 is provided with band chain orifice plate, and chain lock 14, can be by handwheel 10 lockings by handwheel spoke with the chain hole on chain orifice plate.
During unlatching, thereby by handwheel 10, driving Stem Mut 9 to rotate band ovable valve stem 5 rises, spheroid 2 and elastic seat 3 are departed from, and when directional post 7 enters valve rod spiral chute, valve rod 5 rotates and rises, drive spheroid 2 rotations, until valve opening, chain lock 14 is through handwheel spoke with the chain hole on chain orifice plate, with locking, handwheel 10 can not rotate, and valve can not be closed; While closing, thereby by handwheel 10, drive Stem Mut 9 to rotate with ovable valve stem 5 under the effect of directional post 7, rotate and decline, drive spheroid 2 rotations, until directional post 7 is while entering the straight trough of valve rod 5, valve rod 5 declines, and the wedge pressure by valve rod 5 compresses spheroid 2 and elastic seat 3 seal, valve closing, chain lock 14 is through handwheel spoke with the chain hole on chain orifice plate, with lock, lock, handwheel 10 can not rotate, and valve can not be opened.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
