Abstract
The utility model belongs to the gate valve field does not have the function cut off to current gate valve to cause a stupalox type gate valve who leaks and provide. Including valve body, flashboard, valve rod, filler mechanism, stand, connecting plate and executor, be equipped with ceramic disk seat at valve body inner chamber entrance point, the flashboard include metal flashboard and ceramic flashboard, ceramic flashboard is fixed on the metal flashboard, and ceramic flashboard installs in one side of the ceramic disk seat of orientation, makes gate valve ceramic flashboard under the closure state connect the valve rod with ceramic valve seat seal cooperation, metal flashboard upper end, metal flashboard lower extreme cross section be the tilting structure, and the notched most advanced part of this tilting is located on one side of the ceramic flashboard. There is sword type angular cut stupalox type gate valve's flashboard utensil bottom, has the shearing efficiency, can strike off the adhesion on the face of glossing over a fault, the automatic clear debris. This valve has high stand wear and tear, corrosion -resistant, anti high -temperature behavior, and thermal -insulated nature is good, and thermal expansion coefficient is little to make the valve longe -lived.
Description
Technical field
The utility model belongs to gate valve field, particularly relates to a kind of ceramic blade type gate valve.
Background technique
Existing gate valve does not generally have the function of cut-out, often there will be material and is stuck between flashboard and valve body, cause leakage; material is stuck between flashboard and valve body for a long time simultaneously; make valve rod be in deformation state for a long time, get off to make valve rod to be out of shape for a long time, finally cause gate valve to leak.
Model utility content
The purpose of this utility model does not have cutting function for existing gate valve to cause and leak and the one pottery blade type gate valve that provides.
The utility model is achieved by the following technical solution:
Pottery blade type gate valve, comprise valve body, flashboard, valve rod, filling body, column, connecting plate and final controlling element, final controlling element output terminal connects valve rod, and actuate valve stem moves up and down, filling body comprises filler and Gland, filler is located between flashboard and valve body, Gland is arranged on valve body, ceramic valve seat is provided with at body cavity entrance point, described flashboard comprises metal flashboard and ceramic flashboard, pottery flashboard is fixed on metal flashboard, and ceramic flashboard is arranged on towards the side of ceramic valve seat, ceramic flashboard and ceramic valve seat are sealed and matched in closed state to make gate valve, metal flashboard upper end connects valve rod, metal flashboard lower end cross section is tilting structure, and the tip part of this tilting otch is located at ceramic flashboard side.
Metal flashboard has the annular receiving groove of an accommodation pottery flashboard, and ceramic flashboard is embedded in this receiving groove.
There is at described ceramic flashboard outer surface inner ring the sunk part of an annular, metal flashboard is fixed with one by screw and ceramic flashboard is fixed on pressing plate on metal flashboard, and the outer surface of ceramic flashboard flushes or protrude from pressing plate outer surface with the outer surface of pressing plate.
Described final controlling element is pneumatic actuator.
The simple tool of the utility model structure has the following advantages:
1. have blade type angular cut bottom the flashboard tool of ceramic blade type gate valve, have shearing effect, scraped glosss over a fault the adhesion on face, automatically removes foreign material;
2. ultrashort structure length, save material, the more traditional gate valve weight saving of weight is about 20%-30%, and pipe-line system overall weight can be made greatly to alleviate, and installation and maintenance are convenient;
3. use this valve can improve the closedown sealability of delivery pipeline system, stop to greatest extent to leak, to enhancing productivity, protection of the environment will play positive progradation;
4. when adopting pneumatic actuator, adopt column to be connected with valve, structure is simple, with low cost, reliable performance, and output torque is large; Its control can do local and remote control, can also realize remote location display and remote control according to the requirement of user;
5. sealing surface of seat material adopts structural ceramics manufacture, adopt embedding technique, its chemical stability and extreme hardness, therefore this valve has high wear-resistant, corrosion-resistant, high temperature resistant property, and thermal insulation is good, thermal expansion coefficient is little, thus makes life of valve long, and cost performance comparatively common valve improves 10 times.
