Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of lined ceramics angie type discharging valve that is used to carry alum earth mud.
Background technique
The angie type modulating valve is widely used class valves such as metallurgical alumina factory, medium by it is alum clay, ore, slip, wherein contain bauxitic ore, alkali, water, because the hardness of ore often reaches HRC＞60, the flow velocity that adds slip is up to 30-50m/s, when so pulp flow is crossed valve to valve wash away, wear and tear quite serious, especially to the valve seat of valve, valve head, valve body wash away, wear and tear, corrode even more serious.The sealing surface of valve is the key position of valve, and the valve seat of valve, the crucial exactly sealed member of flap.But at present the valve head of angie type modulating valve and valve seat are because its hardness is low, and structural design is unreasonable, make angie type modulating valve sealing pair under the washing away of mud, wear and tear, seriously corroded, greatly reduce the working life of valve.
The model utility content
The purpose of this utility model provides a kind of lined ceramics angie type discharging valve, and it has in use improved the working life of valve greatly.
For solving the problems of the technologies described above, the utility model comprises: valve body, and valve body top connects support, the support below is provided with Gland, and valve rod is positioned at the runner of valve body, and the bottom of valve rod connects ceramic flap, the bottom of valve body connects ceramic valve seat, and ceramic flap is positioned at the below of ceramic valve seat.
The pottery flap comprises: valve petal body, and the top of valve petal body is provided with domatic along circumference, and the axis of valve petal body is provided with attachment hole, establishes connecting sleeve in the attachment hole, and connecting sleeve connects gland.
Ceramic valve seat is a ceramic cylinder, and the top of ceramic cylinder is provided with fin along the circumference of ceramic cylinder outer wall.
The body cavity wall is provided with ceramic coating.
Be provided with floral disc in the body cavity.
Support top connects Stem Mut, the Stem Mut valve rod that is threaded.
The both sides of support are provided with chute, connect limiting board on the valve rod, and limiting board inserts in the chute.
Ceramic flap and the ceramic valve seat of the utility model by cooperatively interacting, in pipeline in the process of slurry conveyed, washing away, wear and tear, corroding reduction, the working life of having improved valve greatly ceramic flap and ceramic valve seat.

Embodiment
First kind of mode of execution of the present utility model: comprise as Fig. 1, Fig. 2 and the utility model shown in Figure 3: valve body 3, valve body top connects support 6, and the support below is provided with Gland 5.The both sides of support are provided with chute, connect limiting board 10 on the valve rod, and limiting board inserts in the chute, and limiting board is used to prevent the rotation of valve rod, make valve rod can only upper and lower to motion.Valve rod 8 is positioned at the runner of valve body, and the bottom of valve rod connects ceramic flap 1, the bottom connecting pipeline of valve body, the flange of pipeline is connected with valve body, the flange of pipeline is pressed in the bottom of valve body with ceramic valve seat 2, thereby valve body and pipeline are connected as a single entity, and ceramic flap 1 is positioned at the below of ceramic valve seat.Be provided with floral disc 4 in the body cavity, floral disc is connected with valve body, and the floral disc center has through hole, and through hole is used for by valve rod, prevents valve rod generation deformation to support valve rod.The pottery flap comprises: valve petal body, and the top of valve petal body is provided with domatic along circumference, and the axis of valve petal body is provided with attachment hole, establishes connecting sleeve in the attachment hole, will valve rod be installed in the connecting sleeve, and the connecting sleeve gland that is threaded connects as one valve rod and flap.Support top is provided with the drive unit chamber, places Stem Mut 7 in the drive unit chamber, top, the drive unit chamber Stem Mut gland that is threaded, the Stem Mut valve rod that is threaded.Ceramic valve seat 2 is a ceramic cylinder, and the top of ceramic cylinder is provided with fin along the circumference of ceramic cylinder outer wall.
Pottery flap and ceramic valve seat employing weight ratio are 97% Al
2O
3, 3% TiO
2Mixture sintering forms, and adopts the martensitic phase transformation toughening technology in sintering process, has improved the toughness and the elasticity of ceramic valve head and ceramic valve seat, makes ceramic valve head and ceramic valve seat be convenient to processing.
As improvement of the present utility model, on body cavity, be provided with ceramic coating, ceramic coating adopts the Al of weight ratio 97%
2O
3, 3% TiO
2Mixture at detonation flame spraying more than 1800 ° on body cavity, to increase the wear resistance of valve pocket.
When using the utility model, by handwheel 9 or the rotation of driven by motor Stem Mut that is connected with valve rod, Stem Mut rotation makes valve rod mention or put down, connected ceramic flap is upper and lower to be moved and valve rod drives, when ceramic flap falls with valve rod, the domatic and ceramic valve seat on ceramic flap top bottom disengages and makes valve open; When valve rod is mentioned, the domatic and ceramic valve seat on ceramic flap top bottom compresses and makes valve closes.
