Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of frost-cracking-preventing ball valve.
Background technology
nullValve is the most universal in people's daily life，Also seem unknown to the public，Existing ball valve does not the most design this technology antifreeze，Therefore interim much not carry out valve that insulation protection prepares and cause the water freezing in valve to be split up valve because of low temperature at cold wave，Cause the leakage waste water resource of water，Bring property loss simultaneously，Northern area often selects to avoid valve to freeze to overcoat insulation on valve sleeve，And southern area is not because being tested by sub-zero weather for a long time，Valve is made often not have suitable Insulation，Finally when cold wave arriving temperature is less than time subzero，Water has anti-expansion characteristics between 0 DEG C-4 DEG C，When 4 DEG C，Density is maximum (1.00g/cm3)，It is as cold as 0 DEG C of ice formed，Density reduces (0.92g/cm3) that is pyrocondensation (referring to 4 DEG C) cold rise (referring to 0 DEG C) on the contrary，Water freezing produces anti-swelling，This results in, and valve is large quantities of to be occurred by the situation of bursting by freezing，Tradition frost-cracking-preventing valve employing is offered the counter of generation when relief hole carrys out drain in-core water freezing and is expanded volume，But the design of relief hole can make valve produce certain leakage，Structure is the most complicated simultaneously，Reliability is the lowest，More easily go wrong.
Utility model content
Based on the problems referred to above, the utility model purpose is to provide a kind of frost-cracking-preventing ball valve, has good airproof performance No leakage, and the volumetric expansion produced that freezes can be born in built-in elastic space, prevents the feature of bursting by freezing.
nullFor problem above，Provide following technical scheme: a kind of frost-cracking-preventing ball valve，Including valve seat、It is arranged at the left valve gap in described valve seat left side、It is arranged at the right valve gap in described valve seat right side，It is provided with valve pocket in described valve seat，Spool and the valve rod being hinged with spool it is provided with in described valve pocket，Described valve rod is provided with handle，Described left valve gap and right valve gap are equipped with the water channel communicated with valve pocket，It is provided with contraction chamber in described valve pocket，Described contraction chamber is positioned at bottom valve pocket，It is provided with contraction block in described contraction chamber，Described contraction block is hollow rubber capsule，Described contraction block volume is more than contraction chamber，And it is resilient interference fit installation with contraction chamber，The water channel inwall of described left valve gap and right valve gap is equipped with internal channel，Described water channel inwall internal channel is at least one，It is provided with contractile ring in described internal channel，Described contractile ring is hollow rubber ring，Described contractile ring caliber is more than internal channel width，And it is resilient interference fit installation with internal channel.
Further, being filled with compressed air to overcome contraction block not produce contraction under the pressure of water inside described contraction block, keep enough space for accommodating the anti-volume that expands that water freezing produces, described contraction block variable shrinkage volume is more than the 1/10 of valve pocket internal volume.
Further, being filled with compressed air inside described contractile ring keeps elasticity not produce contraction under the pressure of water to overcome, the space keeping enough expands volume for accommodating the counter of water freezing generation, described contractile ring variable shrinkage volume is more than the 1/10 of water channel volume, is changed into the volume ratio of solid-state from liquid meeting water.
Further, the pressure of described contraction block charged air pressure internal with contractile ring is consistent with the pressure in pipeline, or also keeps pressure reduction, to reach the purpose of balance contraction volume according to the different application occasion different balance pressure of filling.
The beneficial effects of the utility model, the utility model uses the anti-swelling that built-in elastic space produces when absorbing water freezing, valve is avoided to cause valve bursting by freezing in season in severe winter because freezing, the utility model can recover original elastic space after frozen water melts voluntarily, the test frozen can be stood for a long time, reduce the property loss that people cause because of valve bursting by freezing pipeline leakage in cold wave.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating the utility model, but are not limited to scope of the present utility model.
nullReferring to figs. 1 to shown in Fig. 4，A kind of frost-cracking-preventing ball valve，Including valve seat 1、It is arranged at the left valve gap in described valve seat 1 left side 2、It is arranged at the right valve gap in described valve seat 1 right side 3，It is provided with valve pocket 10 in described valve seat 1，Spool 11 and the valve rod 12 being hinged with spool 11 it is provided with in described valve pocket 10，Described valve rod 12 is provided with handle 121，Described left valve gap 2 and right valve gap 3 are equipped with the water channel 4 communicated with valve pocket 10，It is provided with contraction chamber 13 in described valve pocket 10，Described contraction chamber 13 is positioned at bottom valve pocket 10，It is provided with contraction block 131 in described contraction chamber 13，Described contraction block 131 is hollow rubber capsule，Described contraction block 131 volume is more than contraction chamber 13，And it is resilient interference fit installation with contraction chamber 13，Water channel 4 inwall of described left valve gap 2 and right valve gap 3 is equipped with internal channel 40，Described water channel 4 inwall internal channel 40 at least one，It is provided with contractile ring 41 in described internal channel 40，Described contractile ring 41 is hollow rubber ring，Described contractile ring 41 caliber is more than internal channel 40 width，And it is resilient interference fit installation with internal channel 40.
Described contraction block 131 is internal is filled with compressed air to overcome contraction block 131 not produce contraction under the pressure of water, the space keeping enough expands volume for accommodating the counter of water freezing generation, described contraction block 131 variable shrinkage volume is more than the 1/10 of valve pocket 10 internal volume, for accommodating the volumetric expansion that between valve pocket 10 and spool 11, liquid icing causes.
The internal compressed air that is filled with of described contractile ring 41 keeps elasticity not produce contraction under the pressure of water to overcome, the space keeping enough expands volume for accommodating the counter of water freezing generation, described contractile ring 41 variable shrinkage volume is more than the 1/10 of water channel 4 volume, for accommodating the volumetric expansion that the liquid icing in left valve gap 2 and right valve gap 3 causes, water has anti-expansion characteristics between 0 DEG C-4 DEG C, when 4 DEG C, density is maximum (1.Q0g/cm3), it is as cold as 0 DEG C of ice formed, density reduces (0.92g/cm3) that is pyrocondensation (referring to 4 DEG C) cold rise (referring to 0 DEG C) on the contrary, when the water has frozen, volume increases 1/10, therefore meet water and be changed into the expansion space of solid-state from liquid.
