Description
Technical field
The present invention relates to a kind of ceramic gate valve, be applicable to the control of fluid, as the control of the class quasi-fluids such as mud, silt.
Background technique
The flashboard of prior art, valve seat are generally steel part, its surface hardness is lower than ceramic hardness, not wear-resisting, resistance to erosion not, as easy as rolling off a logly be subject to washing away of fluid and corrode sealing surfaces, destroy sealing surface, easily cause valve leak, and when it adopts stainless steel, cost can improve again, and stainless steel material also easily occurs wearing and tearing after having grown service time, and then causes valve leak.Referring to notification number, be CN202708259Y, open day is the patent document on January 30th, 2013, and its flashboard adopts stainless steel, and cost is higher, easily causes valve leak.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing above-mentioned deficiency in prior art, and a kind of reasonable in design is provided, and cost is low, is difficult for corrosion leakage, and flashboard closing position can be adjusted, the non-damageable ceramic gate valve of flashboard.
The present invention solves the problems of the technologies described above adopted technological scheme: this ceramic gate valve, it is characterized in that by loading and unloading cleaning plate, valve body, ceramic valve seat, pottery flashboard, lower valve rod, valve gap, upper valve rod, pressing plate, sleeve, adjusting nut, Anti-rotary block, column, final controlling element forms, in valve body bottom, be provided with and can load and unload cleaning plate, pressing plate is housed on valve body, ceramic valve seat is housed can load and unload between cleaning plate and pressing plate, sleeve is housed above pressing plate, sleeve is provided with valve gap, valve gap is connected with valve body pipeline, column one end is contained on valve gap, the column the other end is fixedly connected with final controlling element, adjusting nut is housed on column, lower valve rod lower end is connected with ceramic flashboard, lower valve rod upper end is contained on Anti-rotary block, Anti-rotary block is stuck in column limited impression and coordinates with adjusting nut, Anti-rotary block is connected with upper valve rod, upper valve rod is connected with final controlling element.
The column the other end of the present invention is fixedly connected with final controlling element by adpting flange.
The present invention pottery flashboard has gap with can load and unload between cleaning plate, can load and unload cleaning plate and be fixed on bottom valve body by bolt or screw.
At valve body pipeline when ceramic flashboard of the present invention cuts out, circumferentially all there is surplus.
Reasonable in design of the present invention, cost is low, is difficult for corrosion leakage, and flashboard closing position can be adjusted, and can load and unload cleaning plate valve for convenience detach and cleaning, and flashboard is not fragile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Referring to Fig. 1, embodiment of the present invention ceramic gate valve mainly forms by loading and unloading cleaning plate 1, valve body 2, ceramic valve seat 3, ceramic flashboard 4, lower valve rod 6, valve gap 7, upper valve rod 8, pressing plate 9, sleeve 10, adjusting nut 11, Anti-rotary block 12, column 13, final controlling element 15.In the mesopore bottom of valve body 2, be provided with and can load and unload cleaning plate 1, pressing plate 9 is equipped with on top, ceramic valve seat 3 is housed can load and unload between cleaning plate 1 and pressing plate 9.Sleeve 10 is housed on pressing plate 9, and sleeve 10 is pushed down by valve gap 7, and valve gap 7 interconnects with valve body 2 use bolts, can load and unload like this cleaning plate 1, valve body 2, ceramic valve seat 3, pressing plate 9, sleeve 10, valve gap 7 and form each other static annexation.
1. column 13 one end are contained on valve gap 7, and the other end is connected on adpting flange 14, and final controlling element 15 is housed on adpting flange 14.Adjusting nut 11 is equipped with in column 13 positions, middle and lower part.
2. lower valve rod 6 lower ends are sold 5 by hole and are connected with ceramic flashboard 4, and other end is contained on Anti-rotary block 12, and Anti-rotary block 12 is stuck in column 13 limited impressions and coordinates with adjusting nut 11, can prevent from rotating.Anti-rotary block 12 is the parts that connect lower valve rod 6 and upper valve rod 8.Upper valve rod 8 is connected with final controlling element 15.
The working principle of the present embodiment is as follows:
1. final controlling element 15 is power equipments of lifting pottery flashboard 4, open and close exactly the power equipment of ceramic flashboard 4, when final controlling element 15 activates to open ceramic flashboard 4, upper valve rod 8 starts to rising, by Anti-rotary block 12, drive lower valve rod 6 also to rising, ceramic flashboard 4 is sold 5 with lower valve rod 6 by hole and is connected, along with lower valve rod 6 rises, pottery flashboard 4 also rises, and so ceramic flashboard 4 has just been opened gradually.The process that pottery flashboard 4 cuts out in contrast.
2. when ceramic flashboard 4 is closed to terminal, Anti-rotary block 12 just withstands on adjusting nut 11, no longer toward declining, because adjusting nut 11 positions can be adjusted, closing position can be adjusted, and ceramic flashboard 4 and can load and unload 1 of cleaning plate and have certain gap, can load and unload cleaning plate 1 and be fixed on valve body 2 bottoms by bolt or screw, guarantee that ceramic flashboard 4 can not encounter the bottom that can load and unload cleaning plate 1, prevent that ceramic flashboard 4 from receiving that external impacts is damaged.
3. with pottery, do the open-shut device (opening and closing part) of valve and seal valve seat is that an original creation designs, can effectively improve the intensity of wear-resisting, the resistance to erosion of valve sealing face.
The improvements of the present embodiment are:
1. flashboard and valve seat adopt stupalith, can improve the intensity of wear-resisting, the resistance to erosion of valve sealing face, solve the problem that sealing surface is easily etched.
2. the present embodiment increases the positioning device of adjusting nut 11 on column 13, can avoid ceramic flashboard 4 impacted and damage with valve body 2 bottoms collisions closing after putting in place.
3. when ceramic flashboard 4(closes) it circumferentially all has valve body pipeline 16 a part that surplus 17(exceeds valve body pipeline 16 diameters), make the present embodiment sealing effect good, be more difficult for leaking.
The loaded and unloaded cleaning plate 1 being equipped with in valve body 2 bottoms, when valve was used after a period of time, opening appears in ceramic flashboard 4 closes difficulty, or occurs that valve has leakage situation, can directly unload and can load and unload cleaning plate 1, and ceramic valve seat 3 or ceramic flashboard 4 are changed.
The simple deformation of the technology of the present invention feature or technological scheme and combination, should think and fall into protection scope of the present invention.
