During the locating part 21 of structure processed, this as the tower spring of elastic component 23 to the active force of piston piece 22 with fluid pressure to piston piece 22
Active force balances each other；Owing in pipeline or instrument, fluid pressure is relatively big, for being further ensured that resilience effect, also may be used in plunger shaft 20
To be filled with compressed air, this compressed air acts on piston piece 22 to apply one towards plunger shaft 20 opening to this piston piece 22
The assistance force of end, this kind of device is applicable to the pipeline of higher pressure.
In conjunction with Fig. 1, Fig. 2 and Fig. 3,
Being further opened with the second containing cavity 11 relative to the position of the first containing cavity 12 on housing 1, in this embodiment, this is second years old
Water meter movement assembly (not shown) is installed in containing cavity 11, and then makes the fluid pipeline transmission of this embodiment and storage set
Standby frost crack proof device forms a preventing frostbite water meter.
Second containing cavity 11 is the cavity run through, including first end 111, Yi Jiyi connected with described flowing lumen 10
The second end 112 connected with the outside of described housing 1；Water meter movement assembly is loaded this second containing cavity 11 by the second end 112,
And measure in impeller immersion flowing lumen 10, then it is fixedly installed in this second end 112；And this first end 111 is just to described pressure release
The piston piece 22 of device 2 is arranged, and after setting expansion, piston piece 22 deviates from this first end motion at first, at utmost to reduce water
Pressure at table cartridge assemblies, it is to avoid weak part, such as water meter movement assembly, the second end mounting structure etc., stress is damaged by pressure, plays
The technique effect of optimal frost-cracking-preventing.
For realizing simplification structure and installation exercise, first, second end 111,112 of described second containing cavity 11 is the most just
First containing cavity 12 is arranged, and the overall dimensions of described pressure relief device 2 matches with the inner chamber size of this second containing cavity 11,
So that this pressure relief device 2 can load in the first containing cavity 12 by this second containing cavity 11, to play the effect simplifying structure.
It is understood that in other specific embodiments, the transmission of this fluid pipeline and the frost crack proof device of storage device
Housing can also is that a siphunculus, such as square bend pipe or greater angle, the siphunculus of more complicated structure, or storage container, logical
Forming containing cavity in pipe, this pressure relief device loads in this containing cavity, and makes the piston piece of pressure relief device just siphunculus be solidified stress
Centrostigma or weak spot, all can realize anti-frost-cracking technology effect.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model can be made a variety of changes, be protection domain of the present utility model.
