Abstract
The present invention relates to a kind of antifrost butterfly valve, including wafer type handle, valve body, valve rod, valve plate, the coaxial package valve rod in valve body, in the bottom coaxial package valve plate of valve rod, valve seat is installed between valve interior wall and valve plate, described valve plate is Copper substrate, and hydrophobic coating is coated on the surface of Copper substrate.The thickness of the hydrophobic coating is 10~20um.The surface coating hydrophobic coating of valve plate Copper substrate of the present invention, delays the water condensation time, so as to avoid in valve plate surface frost, influenceing the sealing and precision of valve plate.
Description
Technical field
The invention belongs to valve manufacture field, is related to butterfly valve, especially a kind of antifrost butterfly valve.
Background technology
Brass is widely used because it has the characteristics that good mechanical property, Cutting free, excellent heat conductivity, intensity are high, corrosion-resistant
In valve manufacture field.But the water vapour in hot-air condenses into the globule when running into cold surface first.Copper surface and water connect
Feeler is smaller, and water increases after the extravagance of copper surface with the contact area on cold surface, causes heat transfer area to increase, therefore frosting velocity
Comparatively fast.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of antifrost butterfly valve, effectively solve valve
The frosting problem of plate.
The technical proposal for solving the technical problem of the invention is：
A kind of antifrost butterfly valve, including wafer type handle, valve body, valve rod, valve plate, the coaxial package valve rod in valve body,
The bottom coaxial package valve plate of valve rod, valve seat is installed between valve interior wall and valve plate, described valve plate is Copper substrate, in Copper substrate
Surface coating hydrophobic coating.
Moreover, the thickness of the hydrophobic coating is 10~20um.
Moreover, the hydrophobic coating is the composite comprising Kynoar and modified nano calcium carbonate.
The advantages and positive effects of the present invention are：
1st, the surface coating hydrophobic coating of valve plate Copper substrate of the present invention, delays the water condensation time, so as to avoid in valve plate table
Face frost, influence the sealing and precision of valve plate.
2nd, the present invention is carried out Kynoar and modified nano-calcium carbonate compound, utilizes fluorine material dredging in itself
Water-based and nano-calcium carbonate can improve the performance of coating roughness, obtain with high hydrophobic, high abrasion coating.
Brief description of the drawings
Fig. 1 is the structure chart of this butterfly valve；
Fig. 2 is the layer structure schematic diagram of valve plate.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of antifrost butterfly valve, including wafer type handle 1, valve body 3, valve rod 2, valve plate 5, the coaxial package valve in valve body
Bar, in the bottom coaxial package valve plate of valve rod, valve seat 4 is installed between valve interior wall and valve plate.
The innovative point of the present invention is：
Described valve plate is Copper substrate 5-1, and hydrophobic coating 5-2, the thickness of the hydrophobic coating are coated on the surface of Copper substrate
Spend for 10~20um.
The hydrophobic coating can be prepared by a variety of methods,
A kind of preparation method is now enumerated, step is as follows：Kynoar is dissolved in DMF, 10% solution is made, so
Nano-calcium carbonate, FAS-17 are added in the solution afterwards, adds a few drop aqueous acetic acids, 24h is stirred at 50 DEG C, is sprayed on copper
On matrix, 240 degrees Celsius of baking 10min, hydrophobic coating is formed.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, on the premise of inventive concept is not departed from, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.
