Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of antifreeze ball valve.
Background technique
Ball valve is under the pressure of medium, spheroid can produce certain displacement and be pressed on the sealing surface of outlet section, guarantees outlet end sealing, ball valve as long as feature is compact structure own, sealing is reliable, simple in structure, easy to maintenance, sealing surface and the sphere closed state of being everlasting, be difficult for by medium erosion, easy operating and maintenance, be applicable to the general work media such as water, solvent, acid and rock gas, but also be applicable to the severe medium of operating conditions.
The ball valve that had in the market, is mainly comprised of valve body, spheroid and handle, and when passing into water, opening ball valve, the passage of water from spheroid passes through; When closing ball valve, water in spheroid passage is owing to there is no power, just stayed in the passage of spheroid, then along spheroid, flow to the inside, space between spheroid bottom and valve body, and space between general ball for ball valve bottom and valve body all do not have drainage means, so within water just stayed space, winter, the water of staying in space will freeze, and spheroid and valve body are frozen, and ball valve cannot be used; And also can corrode spheroid and valve body after water is of a specified duration in space, reduced the working life of ball valve, also have in the market and below space, to have weep hole, then on weep hole, be provided with sealing plug, but this structure needs people's going regularly to open sealing plug carrys out draining, if not still can be frozen in, so just seem very inconvenient.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of a kind of antifreeze ball valve that can be antifreeze.
For achieving the above object, the utility model provides following technological scheme: a kind of antifreeze ball valve, comprise valve handle, valve rod, valve body and spheroid, described valve handle is fixedly connected with spheroid by valve rod, described spheroid bottom is fixedly connected with flap, described valve body is provided with groove with respect to flap below, described flap bottom surface and bottom portion of groove fit, described bottom portion of groove is provided with through hole, and described flap has closes the second place that the primary importance of through hole and ball valve are opened through hole when completely closed when ball valve is opened completely.
By adopting technique scheme, when valve handle starts to rotate, valve handle is fixedly connected with spheroid by valve rod, spheroid bottom is fixedly connected with flap, so flap just follows spheroid to rotate together, when opening ball valve completely, flap can cover the through hole on groove completely, so just effectively prevent leaking of ball valve, when closing ball valve, flap follows spheroid to rotate, when closing ball valve completely, flap can forward the other end of groove through hole to, so at this moment flap does not just block through hole, then spheroid bottom will spill out along through hole with the interstitial water of valve body, so just water effectively can have been discharged, form an automatic drain system, ball valve can be frozen in because of interstitial water, the possibility that provides ball valve to use under cold snap, so also can make the time that ball valve is corroded greatly reduce, increased greatly the life-span of ball valve.
The utility model is further set to: described spheroid and flap are integrated setting.
By adopting technique scheme, spheroid and flap are integrated setting, and flap is just more firm with being connected of spheroid like this, flap be there will not be because there is fracture with spheroid joint, cause flap to split away off from spheroid.
The utility model is further set to: the cross section of described groove is fan-shaped.
By adopting technique scheme, the cross section of groove is fan-shaped, fan-shaped feature is that to have a line be circular arc, more round and smooth when so just can make flap rotate in groove, there will not be Caton phenomenon, and can make can better coordinate between groove and flap, the sealing between having increased by two, has also saved the space of ball valve body inside.
The utility model is further set to: described through hole is provided with Air Filter.
By adopting technique scheme, through hole is provided with Air Filter, can effectively prevent that so extraneous dust from entering through hole, then through hole is blocked, and makes through hole ineffective, does not just reach the needed function of ball valve.
The utility model is further set to: the making material of described valve body and spheroid is forged steel.
By adopting technique scheme, the making material of valve body and spheroid is forged steel, and the hardness of forged steel is high, can bear very large pressure and indeformable, and anticorrosive property is strong, can not use for a long time and can get rusty, and has greatly increased the working life of ball valve.
The utlity model has following advantage: simple in structure, durable, when valve handle starts to rotate, valve handle is fixedly connected with spheroid by valve rod, spheroid bottom is fixedly connected with flap, so flap just follows spheroid to rotate together, when opening ball valve completely, flap can cover the through hole on groove completely, so just effectively prevent leaking of ball valve, when closing ball valve, flap follows spheroid to rotate, when closing ball valve completely, flap can forward the other end of groove through hole to, so at this moment flap does not just block through hole, then spheroid bottom will spill out along through hole with the interstitial water of valve body, so just water effectively can have been discharged, form an automatic drain system, ball valve can be frozen in because of interstitial water, the possibility that provides ball valve to use under cold snap, so also can make the time that ball valve is corroded greatly reduce, increased greatly the life-span of ball valve.
