Slag valve.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of separable type lock slag valve, including fixing two valve bodies connected: left and right valve body, lay respectively at left and right valve body it
In two valve seats: left and right valve seat, and one club and pneumatic means, described one club include the valve rod that connects and
Valve ball, wherein, valve rod upper end connects has pneumatic means, valve ball to be positioned among left and right valve seat, and closely cooperates with left and right valve seat,
The open-work that left and right valve channel can be made to connect, described left valve seat and right valve seat it is additionally provided with tight with valve ball on described valve ball
On leakproof fit sealing surfaces, the scraping structure of valve ball is close in the most outwardly formation.
Described left valve barrel is connected composition annular convex with right valve barrel, is sealed and installed with filler sleeve in annular convex,
Described valve rod passes axially through filler sleeve, and and filler sleeve between form the annular recess placing soft graphite, at ring
The top of shape groove is additionally provided with the filler pressing sleeve compressing soft graphite.
Annular gasket also it is wound with between bottom and the valve body of described filler sleeve.
It is provided with stair-stepping toroidal cavity between described valve body and valve seat, in toroidal cavity, is provided with elastic packing knot
Structure, this elastic sealing structure includes the top seal structure being made up of valve body lining, and by spring structure, sealing ring support ring and
The lower seal structure of graphite-seal ring composition, described spring structure, sealing ring support ring and graphite-seal ring depend on from outside to inside
Secondary being arranged between valve body and valve seat, the inside of described valve body lining is additionally provided with graphite plate on the lower surface contacted with valve seat
Root.

The bottom of described one club is also equipped with the graphite pads with valve body contact.Strengthen between one club and valve body
Connection.
Compared with prior art, this utility model has the advantage that
(1) good seal performance: valve body and valve seat, valve body all uses the most suitable sealing with the one attachment structure such as club
Structure seals, to ensure that lock slag valve still can guarantee that enough sealings in the working environment of High Temperature High Pressure.
(2) anti-static effect highlights: be all directly or indirectly to be in close contact between the parts such as valve body, valve seat, integrally club,
Self-assembling formation electrostatic passage, the most not only anti-static effect is good, simultaneously structure also relative simplicity, saves special antistatic
Structure is arranged.
(3) self-cleaning: valve seat, in the setting of the scraping unit on the surface contacted with valve ball, does not only interfere with valve seat and valve
Closely cooperating between ball, simultaneously when one club is when rotating, and the lime-ash of ball surface attachment is removed in scraping unit energy scraping
Deng, self-cleaning function can be realized.
(4) setting of the elastic sealing structure of valve body and valve seat, when locking the work of slag valve, when the switching process at valve
In, usually there will be an axial fine setting between valve seat and valve body, at this moment the elasticity of spring structure self can make effectively benefit
Repaying, simultaneously because metal spring is wrapped up by elastomeric material, it is to avoid when working long hours, the particulate matter fouling in medium blocks
Metal spring and make the problem of its elasticity loss occur.
