Abstract
A ball body structure of an antifreezing ball valve comprises a valve body, a sealing ball body and a valve rod, wherein the sealing ball body and the valve rod are arranged in a valve body inner cavity of the valve body. A through hole for media to flow through is formed in the sealing ball body. An upstream pipeline and a downstream pipeline are further arranged in the valve body inner cavity. The sealing ball body is located between the upstream pipeline and the downstream pipeline. The inner end of the valve rod and the sealing ball body are arranged together. The outer end of the valve rod is exposed out of the valve body. An antifreezing hole communicated with the through hole is formed in the sealing ball body. When the ball valve is in the closed state, the upstream pipeline, the antifreezing hole and the through hole are sequentially communicated. The ball body structure has the advantages of being reasonable in structural design, capable of ensuring safe running of the pipelines, and the like.
Description
Technical field:
The utility model relates to a kind of ball valve, particularly relates to a kind of antifreeze ball valve sphere structure.
Background technique:
Ball valve is as common a kind of valve, and using scope is wide especially.Existing straight-through type ball valve design spheroid only has a through hole, only supplies media flow, there is no antifreeze and decompression function.Such design exists following not enough: in conduit running, work as ball valve in closed condition, and body cavity Yin Wendu raises or other reasons causes pressure anomaly to raise, and can not can make conduit running dangerous by safety relief; In the time that temperature is reduced to the medium that is enough to make to be trapped in ball valve inner chamber and freezes, if now by force Open valve can make seal ring damage, thereby cause whole ball valve to lose efficacy.Therefore, be necessary to be improved.
Model utility content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of reasonable in design is provided, and can guarantee the antifreeze ball valve sphere structure of conduit running safety.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of antifreeze ball valve sphere structure, comprise valve body, be arranged on the sealed spheroid in the body cavity of described valve body, valve rod, in described sealed spheroid, be provided with the through hole for media flow, in described body cavity, be also provided with upstream line and downstream line, described sealed spheroid is between described upstream line and downstream line, described valve rod is inner to be set together with described sealed spheroid, described valve rod outer end exposes to described valve body, described sealed spheroid is provided with an antifreeze hole being communicated with described through hole, when ball valve is during in closed condition, described upstream line, antifreeze hole and through hole are communicated with successively.
Pipeline between described upstream line, through hole and downstream line in described valve body is rectilinear duct.
Described antifreeze hole is vertical with described through hole to be arranged.
Between described sealed spheroid and described body cavity, be also provided with seal ring.
The utility model has the following advantages with respect to prior art tool:
Because the utility model has been offered an antifreeze hole on sealed spheroid, when ball valve is during in closed condition, this antifreeze hole can be reduced the possibility that valve freezes temporarily effectively, and this freeze to cause temporarily valve damage, antifreeze hole is positioned at sealed spheroid upstream, and in the time that medium is trapped in body cavity generation freezing expansion, the effect communicating with upstream medium is played in this antifreeze hole, and extenuate internal pressure, guarantee conduit running safety; When ball valve is during in closed condition, this antifreeze hole can also effectively reduce body cavity Yin Wendu raise or or other reasons cause pressure anomaly raise possibility, and pressure anomaly rising can cause valve blast like this, this antifreeze hole is positioned at sealed spheroid upstream, in the time being trapped in the pressure medium of body cavity and extremely raising, the effect communicating with upstream medium is played in this antifreeze hole, and discharges internal-internal pressure, guarantees conduit running safety.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, a kind of antifreeze ball valve sphere structure providing according to the utility model, comprise valve body 1, be arranged on the sealed spheroid 3 in the body cavity 2 of valve body 1, valve rod 4, in sealed spheroid 3, be provided with the through hole for media flow, in body cavity 2, be also provided with upstream line and downstream line, sealed spheroid 3 is between upstream line and downstream line, valve rod 4 is inner to be set together with sealed spheroid 3, valve rod 4 outer ends expose to valve body 1, sealed spheroid 3 is provided with an antifreeze hole 5 being communicated with through hole, when ball valve is during in closed condition, upstream line, antifreeze hole 5 and through hole are communicated with successively.
Pipeline between described upstream line, through hole and downstream line in valve body 1 is rectilinear duct.Antifreeze hole 5 is vertical with described through hole to be arranged.Between sealed spheroid 3 and body cavity 2, be also provided with seal ring 6.Owing to having offered an antifreeze hole 5 on sealed spheroid 3, when ball valve is during in closed condition, this antifreeze hole 5 can be reduced the possibility that valve freezes temporarily effectively, and this freeze to cause temporarily valve damage, antifreeze hole 5 is positioned at sealed spheroid 3 upstreams, and in the time that medium is trapped in body cavity generation freezing expansion, the effect communicating with upstream medium is played in this antifreeze hole 5, and extenuate internal pressure, guarantee conduit running safety; When ball valve is during in closed condition, this antifreeze hole 5 can also effectively reduce body cavity Yin Wendu raise or or other reasons cause pressure anomaly raise possibility, and pressure anomaly rising can cause valve blast like this, this antifreeze hole 5 is positioned at sealed spheroid 3 upstreams, in the time being trapped in the pressure medium of body cavity and extremely raising, the effect communicating with upstream medium is played in this antifreeze hole 5, and discharges internal-internal pressure, guarantees conduit running safety.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
