Lose it is more serious under conditions of, then to the material of water meter case, structure, more stringent requirements are proposed, it is well known that in shell of water flowmeter
Portion is equipped with all kinds of operation components, such as electronic component, gear, and can pass water through, if shell meets with corrosion or super
Shell fragmentation occurs under low temperature, then can largely effect on the normal use of tap water.
Utility model content
The utility model proposes a kind of anti-corrosion used at ultra-low temperature water meter case aiming at the above problem, the anti-corrosion ultralow temperature
Can be in more corrosion and normal use under condition of ultralow temperature with water meter case, and structure is simple, it is stable.
To reach above-mentioned technical purpose, the utility model uses a kind of anti-corrosion used at ultra-low temperature water meter case, including by not
Become rusty shell, water inlet pipe, outlet pipe made of steel, and the shell and water inlet pipe, outlet pipe be in one-piece connection, the shell, into
The inner wall of water pipe and outlet pipe is uniformly coated with the first anti-corrosion layer, and first anti-corrosion layer is uniformly resistance to coated with one layer outside
Cryosphere；Meanwhile the outer wall of the shell, water inlet pipe and outlet pipe is uniformly coated with the second anti-corrosion layer.
Preferably as the utility model, first anti-corrosion layer is epoxy polyester mixed coating；The low temperature resistant layer
For glass layer；Second anti-corrosion layer is the C/C composite layer mixed by carbon fiber and resin.
As the improvement of the utility model, further include made of polytetrafluoroethylene (PTFE), can and water inlet pipe on the outside of form connection
The first connector sleeve, and can with the second connector sleeve of connection is formed on the outside of outlet pipe, be equipped in first in first connector sleeve
Screw thread, the water inlet pipe outside is equipped with can be with the first female thread at the first external screw thread of threaded connection；Second connector sleeve
It is inside equipped with the second internal screw thread, being equipped on the outside of the outlet pipe can be with the second female thread at the second external screw thread of threaded connection.
The utility model uses the surfaces externally and internally coated with multiple layer erosion shield and low temperature resistant coating in water meter case, can
Make water meter case corrode and condition of ultralow temperature under still normal use；Corrosion-resistant cannula structure is added simultaneously, is further enhanced
The corrosion resistance and leak resistance of water meter case.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and detailed description.
In conjunction with Fig. 1 it is found that a kind of anti-corrosion used at ultra-low temperature water meter case, including be made of stainless steel shell 1, water inlet pipe 2,
Outlet pipe 3.
In above structure, shell 1 and water inlet pipe 2, outlet pipe 3 are in one-piece connection, shell 1, water inlet pipe 2 and outlet pipe
3 inner wall is uniformly coated with the first anti-corrosion layer 4, and one layer of low temperature resistant layer 5 is uniformly coated with outside the first anti-corrosion layer 4；Meanwhile
The second anti-corrosion layer 6 is uniformly coated in the outer wall of shell 1, water inlet pipe 2 and outlet pipe 3.
In the present invention, preferred first anti-corrosion layer 4 is epoxy polyester mixed coating；Preferred low temperature resistant layer 5
For glass layer；And preferred second anti-corrosion layer 6 is the C/C composite layer mixed by carbon fiber and resin.
In above-mentioned coating, epoxy polyester mixed coating mainly uses epoxy resin and polyester resin for main raw material(s) preparation
It forms, is provided simultaneously with the respective special performance of the two, so that the film produced has extremely good levelability, dicoration, machine
Tool performance and stronger corrosion resistance are widely applied to the coating of various indoor metal products.Glass fibre is that a kind of performance is excellent
Different inorganic non-metallic material, it is many kinds of, have good insulating, heat resistance is strong, corrosion resistance is good, high mechanical strength it is excellent
Point；C/C composite layer refers to using carbon fiber or its fabric as reinforced phase, is soaked with the pyrolytic carbon of chemical vapor infiltration or liquid phase
Stain-charing resin carbon, a kind of pure charcoal heterogeneous structure that asphalt carbon is matrix composition.
As the improvements of the utility model, the utility model further includes made of polytetrafluoroethylene (PTFE), can and intake
The first connector sleeve 7 of connection is formed on the outside of pipe 2, and can connect the second connector sleeve 8 with being formed on the outside of outlet pipe 3, is connected first
The first internal screw thread 9 is equipped in female connector 7, the first outer spiral shell being threadedly coupled can be formed with the first internal screw thread 9 by being equipped on the outside of water inlet pipe 2
