Description
Technical field
The utility model relates to valve field, relates to a kind of antifreeze ball valve in particular.
Background technique
Application number be 201320541682.8 Chinese model utility disclose 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, flap is fixedly connected with bottom described spheroid, described valve body is provided with groove relative to below flap, described flap bottom surface and bottom portion of groove fit, described bottom portion of groove is provided with through hole, described flap have to close when ball valve is opened completely the primary importance of through hole and ball valve completely closed time open the second place of through hole.A kind of antifreeze ball valve of the present utility model, structure is simple, durable, effectively spheroid and the interstitial water of valve body can be emitted timely, ball valve can not be frozen in because of interstitial water, water is discharged and also makes the time that ball valve is corroded greatly reduce, considerably increase the life-span of ball valve.
Known to above-mentioned patent specification [0023], when valve handle starts to rotate, valve handle is fixedly connected with spheroid by valve rod, flap is fixedly connected with bottom spheroid, described flap just follows spheroid to rotate together, when opening ball valve completely, through hole on groove can cover by flap completely, so just serve and effectively prevent leaking of ball valve, when closing ball valve, flap can follow spheroid to rotate, when closing ball valve completely, flap can forward the through hole the other end of groove to, through hole does not just block by described at this moment flap, then the bottom of spheroid and the interstitial water of valve body will spill out along through hole, thus reach the object effectively discharged by water.
But the applicant finds that the patented product is in the using process of reality, because ball valve is in use open ball valve completely, and supply water within the longer time, but in the winter time or arctic weather, the bottom of spheroid and the interstitial water of valve body still can be frozen, thus well can not play an antifreeze effect, the reason of above-mentioned phenomenon is caused to be: the Figure of description with reference to this patent above-mentioned illustrates, in the Figure of description 1 and accompanying drawing 2 of this patent, when opening ball valve completely, although flap effectively prevents leaking of ball valve, but owing to can't flow between this space in the bottom of spheroid and the interstitial water of valve body, the water of quiescent flow state still easily can be frozen in the winter time or between this space of arctic weather, ball valve cannot normally be used, even after this interstitial water freezing, also can corrode spheroid and valve body, reduce the working life of ball valve.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of effectively in the winter time or under arctic weather, avoids the water in ball valve to be frozen in, improves the antifreeze ball valve in working life.
For achieving the above object, the utility model provides following technological scheme: a kind of antifreeze ball valve, include valve handle, valve rod, valve body and spheroid, described valve handle is fixedly connected with spheroid by valve rod, the bottom of described spheroid is fixedly connected with flap, the middle part of described spheroid is provided with passage, bottom and the valve body of spheroid are formed with space, described valve body is provided with groove relative to below flap, the bottom surface of described flap and the bottom of groove fit, the bottom of described groove is provided with through hole, described flap have to close when ball valve is opened completely the primary importance of through hole and ball valve completely closed time open the second place of through hole, described passage includes water intake and water outlet, described spheroid is offering the first micropore and the second micropore respectively on the position of water intake and water outlet, described passage and space are by the one or two micropore, second micropore is conducted.
By adopting technique scheme, on the position of water intake and water outlet, the first micropore and the second micropore is offered respectively at spheroid, thus make between passage and space by the one or two micropore, second micropore is conducted, opening in ball valve process completely like this, because flap just follows spheroid to rotate together, thus the through hole on groove will cover by flap completely, serve and prevent the water in ball valve from outwards spilling, and in the process of ball valve work, most water can flow into from water intake and flow out water outlet along passage, and have the water of a small part to be can flow in space along the first micropore, and flow to water outlet from the second micropore, in this above-mentioned whole process, by the setting of the first micropore and the second micropore, the water in space is made to rest in space for a long time, thus reduce the water phenomenon icing in space, and when closing ball valve, flap can follow spheroid to rotate, when closing ball valve completely, flap can forward the through hole the other end of groove to, through hole does not just block by described at this moment flap, then the bottom of spheroid and the interstitial water of valve body will spill out along through hole, thus reach the object effectively discharged by water, pass through this set, water in space can not be rested in space for a long time, thus reduce the water phenomenon icing in space, use under enabling this ball valve be adapted to arctic weather, also make to avoid the corrosion of freezing to ball valve, add the working life of ball valve.
The utility model is set to further: described through hole is positioned at the lowermost end of valve body.
By adopting technique scheme, when closing ball valve completely, make flap can forward the through hole the other end of groove to, through hole does not just block by described at this moment flap, then the through hole that the bottom of spheroid and the interstitial water of valve body will be arranged along lowermost end spills out, thus reaches the object completely, effectively discharged by interstitial water.
The utility model is set to further: the aperture of described first micropore all increases along direction, space gradually from passage.
By adopting technique scheme, the water having a small part in passage can flow in space along the first micropore, and flow to water outlet from the second micropore, and in this process, by the setting of the first micropore and the second micropore, water in space can not be rested in space for a long time, thus reduce the water phenomenon icing in space; And by the aperture of the first micropore is increased gradually along direction, space, after making the water flowed in the first micropore flow out the first micropore, reduce the impact of current to valve body, thus add the working life of ball valve.
The utility model is set to further: described spheroid and flap are integrated setting.
By adopting technique scheme, spheroid and flap are integrated setting, and the connection of such flap and spheroid can be more firm, flap be there will not be because occur rupturing with spheroid joint, and cause flap to split away off from spheroid.
The utility model is set to further: the cross section of described groove is fan-shaped.
By adopting technique scheme, the cross section of groove is fan-shaped, fan-shaped feature has a line to be circular arc, it is more round and smooth when flap so just can be made to rotate in a groove, there will not be the phenomenon that card pauses, and can make better to coordinate between groove and flap, add the sealing between two, also save the space in ball valve body wind portion.
The utility model is set to further: described through hole is provided with Air Filter.
By adopting technique scheme, through hole being provided with Air Filter, effectively can preventing extraneous dust from entering in through hole like this, then through hole being blocked, make through hole ineffective, just reach the function required for ball valve.
The utility model is by adopting technique scheme, have the following advantages: by the setting of the first micropore and the second micropore, water in ball valve also can not be frozen under arctic weather, use under enabling this ball valve be adapted to arctic weather, it also avoid the corrosion of freezing to ball valve, add the working life of ball valve.
