Description
Technical field
The present invention relates to a kind of ceramic gate valve, it is applicable to the control of fluid, such as the control of the class quasi-fluid such as mud, silt.
Background technology
The flashboard of prior art, valve seat are generally steel work, its surface hardness is lower than the hardness of pottery, not wear-resisting, not resistance to erosion, extremely easily it is subject to washing away of fluid and corrodes sealing face, breakseal face, it is easy to cause valve leak, and when it adopts stainless steel, cost can improve again, and also easily occurs abrasion after stainless material length duration of service, and then causes valve leak. Being CN202708259Y see notification number, publication date is the patent document on January 30th, 2013, and its flashboard adopts stainless steel, and cost is higher, it is easy to cause valve leak.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned deficiency existing in prior art, and provides a kind of reasonable in design, and cost is low, not easily corrosion leakage, and flashboard is closed position and can be adjusted, the non-damageable ceramic gate valve of flashboard.
The present invention solves the problems of the technologies described above the technical scheme adopted: this ceramic gate valve, it is characterized in that by loading and unloading cleaner plate, valve body, ceramic valve seat, pottery flashboard, lower valve rod, valve gap, upper valve rod, pressing plate, sleeve, setting nut, anti-switch block, column, performer forms, it is provided with bottom valve body and can load and unload cleaner plate, valve body is equipped with pressing plate, ceramic valve seat is housed can load and unload between cleaner plate and pressing plate, sleeve is housed above pressing plate, sleeve is provided with valve gap, valve gap is connected with conduit, column one end is contained on valve gap, the column the other end is fixedly connected with performer, column is equipped with setting nut, the lower end of lower valve rod is connected with pottery flashboard, lower valve rod upper end is contained on anti-switch block, anti-switch block is stuck in column limited impression and coordinates with setting nut, anti-switch block is connected with upper valve rod, upper valve rod is connected with performer.
The column the other end of the present invention is fixedly connected with performer by joint flange.
The present invention's pottery flashboard and can load and unload and have gap between cleaner plate, can be loaded and unloaded cleaner plate and be fixed on bottom valve body by bolt or screw.
Pottery flashboard of the present invention all has surplus in the circumference of conduit when cutting out.
Present configuration is reasonable in design, and cost is low, not easily corrosion leakage, and flashboard is closed position and can be adjusted, and can load and unload cleaner plate valve for convenience detach and cleaning, and flashboard not easily damages.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
See Fig. 1, embodiment of the present invention ceramic gate valve primarily of cleaner plate 1 can be loaded and unloaded, valve body 2, ceramic valve seat 3, pottery flashboard 4, lower valve rod 6, valve gap 7, upper valve rod 8, pressing plate 9, sleeve 10, setting nut 11, anti-switch block 12, column 13, performer 15 form. Being provided with bottom the middle hole of valve body 2 and can load and unload cleaner plate 1, pressing plate 9 is equipped with on top, ceramic valve seat 3 is housed can load and unload between cleaner 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 and valve body 2 are interconnected with bolt, can load and unload cleaner plate 1, valve body 2, ceramic valve seat 3, pressing plate 9, sleeve 10, valve gap 7 like this and form static connection relation each other.
1. column 13 one end is contained on valve gap 7, and the other end is connected on joint flange 14, and joint flange 14 is equipped with performer 15. In column 13, lower portion is equipped with setting nut 11.
2. lower valve rod 6 times end passing hole pins 5 are connected with pottery flashboard 4, and other end is contained on anti-switch block 12, and anti-switch block 12 is stuck in column 13 limited impression and coordinates with setting nut 11, can prevent from rotating. Anti-switch block 12 is the part connecting lower valve rod 6 and upper valve rod 8. Upper valve rod 8 is connected with performer 15.
The principle of work of the present embodiment is as follows:
1. performer 15 is the power-equipment of lifting pottery flashboard 4, it it is exactly the power-equipment opening and closing pottery flashboard 4, when performer 15 activates to open pottery flashboard 4, upper valve rod 8 starts to rising, driving lower valve rod 6 also to rising by anti-switch block 12, pottery flashboard 4 is that passing hole pin 5 is connected with lower valve rod 6, along with lower valve rod 6 rises, pottery flashboard 4 also rises, and pottery flashboard 4 just opens gradually like this. The process that pottery flashboard 4 cuts out is then in contrast.
2. when pottery flashboard 4 is closed to terminal, anti-switch block 12 just withstands on setting nut 11, no longer toward decline, owing to setting nut 11 position can adjust, closed position can be adjusted, pottery flashboard 4 and can load and unload and have certain gap between cleaner plate 1, cleaner plate 1 can be loaded and unloaded and be fixed on bottom valve body 2 by bolt or screw, ensure that pottery flashboard 4 can not encounter the bottom that can load and unload cleaner plate 1, prevent pottery flashboard 4 from receiving external impacts and be damaged.
3. do the opening and closing element (opening and closing part) of valve with pottery and seal valve seat is an original creation design, it is possible to the effectively intensity of wear-resisting, the resistance to erosion of raising valve sealing face.
The improvements of the present embodiment are:
1. flashboard and valve seat adopt stupalith, it is possible to improve the intensity of wear-resisting, the resistance to erosion of valve sealing face, solve the problem that trim is easily etched.
2. the present embodiment increases the locating device of setting nut 11 on column 13, it is possible to avoid pottery flashboard 4 to collide and impacted and damage after closedown puts in place with bottom valve body 2.
3. when pottery flashboard 4(closes) it all has, in the circumference of conduit 16, the part that surplus 17(exceeds conduit 16 diameter) so that the present embodiment sealing effect is good, more not easily leaks.
The loaded and unloaded cleaner plate 1 being equipped with bottom valve body 2, after valve uses for some time, opening occurs in pottery flashboard 4 closes difficulty, or occurs that valve has leakage situation, can directly unload and can load and unload cleaner plate 1, ceramic valve seat 3 or pottery flashboard 4 is changed.
The simple deformation of the technology of the present invention feature or technical scheme and combination, it is intended that fall into protection scope of the present invention.
