Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of steel lining fluorine plastic ceramic valve.
Background technique
Existing ceramic valve is generally be metal by valve design, the runner design of body cavity is stupalith, but be directly lining with between the ceramic body of existing ceramic valve and metal valve body, in use have medium unavoidably to contact with metal valve body, cause the corrosion of metal valve body, shorten the working life of valve.
Model utility content
The purpose of this utility model is a kind of steel lining fluorine plastic ceramic valve provided for existing ceramic valve corrosion-resistant.
The utility model is achieved by the following technical solution:
Steel lining fluorine plastic ceramic valve, comprises valve body, valve gap, valve rod, the bluff body of sealing runner and actuator; Described valve body and valve gap are metalwork, are lined with the runner of stupalith at valve body and valve gap inwall, and bluff body is that stupalith is made, and is lined with fluorine layer between ceramic runner and metalwork.Described lining fluorine layer is that fluoroplastic material is made.Described metalwork valve body and/or metalwork valve gap pass through hot melt extruded technique compact siro spinning technology with lining fluorine layer.
The junction surface that described metalwork valve body and/or metalwork valve gap are connected with lining fluorine layer is provided with draw-in groove, on lining fluorine layer, is provided with on metalwork valve body and/or metalwork valve gap the fixture block matched with draw-in groove accordingly.Described draw-in groove is dovetail groove.
The one side that described lining fluorine layer is connected with metalwork valve body and/or metalwork valve gap is provided with draw-in groove, and the junction surface be connected with lining fluorine layer at described metalwork valve body and/or metalwork valve gap is accordingly provided with the fixture block matched with draw-in groove.Described draw-in groove is dovetail groove.
The beneficial effects of the utility model: whole runner section contacts with material and is stupalith, have splendid flushing resistance; The advantage of ceramic valve, lined with fluoroplastic material valve combines by steel lining fluorine plastic ceramic valve, has splendid corrosion-resistant, resistance to erosion, abrasion resistance properties; Bluff body adopts advanced grinding equipment and manufacture technics, and precision is high, and surface quality is good, with valve seat to after grinding, utilizes the self lubricity of structural ceramics, has good sealability; Revolutionize that metal hard-sealing valve easily leaks, moment of torsion is large, the not corrosion resistant shortcoming of sealing surface; Ceramic valve seat, bluff body have good wear resistance, and make this valve durable in use, reliability is high, long service life, are titanium alloy valve and Monel valve 2 ~ 4 times; This valve is applicable to the granule medium of mordant high hardness, or has corrosion to have again the medium pipeline of soft particle is used as and open and close.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment one
As shown in Figure 1, steel lining fluorine plastic ceramic valve, comprises valve body 1, valve gap 2, valve rod 3, the bluff body 4 sealing runner and actuator 5; Described valve body 1 and valve gap 2 are metalwork, and be lined with the runner 6 of stupalith at valve body 1 and valve gap 2 inwall, bluff body 4 stupalith is made, and are lined with fluorine layer 7 between the runner 6 and metalwork of pottery.Described lining fluorine layer 7 is made for fluoroplastic material.Described metalwork valve body and/or metalwork valve gap pass through hot melt extruded technique compact siro spinning technology with lining fluorine layer.The junction surface that described metalwork valve body and/or metalwork valve gap are connected with lining fluorine layer is provided with draw-in groove 8, on lining fluorine layer, is provided with on metalwork valve body and/or metalwork valve gap the fixture block 9 matched with draw-in groove accordingly.Described draw-in groove is dovetail groove.
