Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The freeze proof air bleeding valve of one as shown in Figure 1, including the discharge chamber 11 in air bleeding valve body 1 and described air bleeding valve body 1,
The housing side of described discharge chamber 11 is provided with anti-freeze protection device, and described anti-freeze protection device includes protection device shell 2, described
It is provided with pressure-releasing chamber 10 in protection device shell 2, in described pressure-releasing chamber 10, is provided with piston 7 and spring 8, one end of described spring 8
Being connected with the bottom of protection device shell 2, the other end of described spring 8 connects piston 7；Described anti-freeze protection device and institute
The connecting portion stating discharge chamber 11 is sealed by sealing member isolation respectively, and described protection device shell 2 is additionally provided with rhone 9, institute
State and outside protection device shell 2, be additionally provided with insulation material protective cover 4, described protection device shell 2 and described insulation material protective cover 4
Between be additionally provided with insulation material 3.
Further, described rhone 9 uses v-shaped structure, groove width 1-2mm and inside and outside wall penetrating.
Further, the material of described protection device shell 2 is food stage 304 and above rustless steel or copper, spheroidal graphite cast-iron, ABS,
Internal diameter is 5-10cm.
Further, described anti-freeze protection device uses Flange joint with the connecting portion of described discharge chamber 11 or threadeds.
Further, described air bleeding valve body 1 material is spheroidal graphite cast-iron.
Further, described sealing member includes one sealing gasket 5 and twice O RunddichtringO 6.
Frost-cracking-preventing air bleeding valve of the present utility model, the volumetric expansion when air bleeding valve crosses the water freezing flowed in cavity, pressure raises and pushes away
Dynamic piston moves, and air bleeding valve is crossed the water of stream intracavity and is injected in anti-freeze protection device, until air bleeding valve endogenous cause of ill volumetric expansion is unnecessary
Water fully enters anti-freeze protection device, and in pressure-releasing chamber, water also freezes and reaches finally to balance, and protects air bleeding valve.When ice melts
During change, volume reduces, and now piston returns to normal address position under the promotion of spring.
This air bleeding valve frost-cracking-preventing protector is also devised with safety drain groove, and the water in having air bleeding valve outer water pipe first freezes, and is squeezed into
In air bleeding valve, volume exceedes water storage cavity limit value, and when the sealing ring of piston second is pushed over rhone, water is through rhone, protection
Air bleeding valve.
A kind of frost-cracking-preventing air bleeding valve of the present utility model, its reasonable in design, by arranging pressure-releasing chamber and rhone, serve
The effect of duplicate protection, thus more effectively prevent air bleeding valve bursting by freezing, there is more preferable safety and practicality.
