Abstract
The invention discloses a ball valve special for polycrystalline silicon. The ball valve comprises a main valve body (1) and an auxiliary valve body (2). A stuffing box (17) is disposed at the upper end of the main valve body (1). A bottom shaft cover (33) is disposed at the lower end of the main valve body (1). A valve seat (3) is disposed in the auxiliary valve body (2). A ball spool (10) is disposed in the middle of the main valve body (1). A valve rod (11) is disposed on the upper portion of the ball spool (10). A cylindrical spring (6) is disposed between the valve seat (3) and the auxiliary valve body (2). Sealing gaskets are disposed on two sides of a pressing ring (7) for mounting the cylindrical spring (6). A valve seat component (8) is disposed on the outer side of each sealing gasket. A first slide bearing (12) is disposed between the valve rod (11) and the lower end of the stuffing box (17). A second slide bearing (34) is disposed between the bottom shaft cover (33) and the ball spool (10). The ball valve special for polycrystalline silicon is reasonable in structural design, fine in airtightness, long in spring service life, safe and reliable, and reasonably uses self-lubricating bearing.
Description
Technical field
The present invention relates to valve, be specifically related to the special-purpose ball valve of a kind of polysilicon.
Background technique
Existing application is in the ball-valve structure simplicity of design of polycrystalline silicon medium, and the valve base sealing reliability is little, is inappropriate for the HTHP occasion, is prone to kill the risk that phenomenon and spring follow the string.Specifically have following problem: one, existing common 3 stops ball valve also exists cylindrical spring to expose the drawback at working medium when realizing the floating valve seat function, has shortened the working life of valve seat and cylindrical spring, the phenomenon that also might occur revealing.Two, existing common 3 stops ball valve uses metal bearing in the joint of lower shaft lid and ball core more; Adopt metal bearing can exist frictional force bigger, moment of torsion is bigger, once operating mode is when abominable; When particle in the medium and powder enter into relative gap, just might there be stuck phenomenon.Three, existing common 3 stops ball valve also uses metal bearings in the joint of valve rod and ball core more, and such contact equally also keeps away the appearance of unavoidable problem two.Four, existing common 3 stops ball valve adopts belleville spring to come the pretension filler to reach sealing here at this piece of packing seal more; Though originally such sealing means possibly reach sealing effect; Once service time permanent words; Belleville spring probably will exist it to lose its original intrinsic elasticity, will inevitably cause leaking once apply working medium pressure.Five, existing common 3 stops ball valve adopts O type circle to reach sealing effect more, has the narrow limitation of applicable working condition.
Summary of the invention
To present ball valve shortcoming, the present invention provides a kind of novel polysilicon special-purpose ball valve.
To achieve these goals, the measure that the present invention taked:
The special-purpose ball valve of a kind of polysilicon comprises the auxiliary valve body of main valve body and both sides thereof, and the main valve body upper end is provided with Stuffing box; The main valve body lower end is provided with the lower shaft lid, is provided with valve seat in the auxiliary valve body, and the main valve body middle part is provided with the ball core that matches with the both sides auxiliary valve body; Ball core top is provided with valve rod, between valve seat and auxiliary valve body, is provided with cylindrical spring, and the trim ring both sides that cylindrical spring is installed are provided with gasket seal; The gasket seal outside is provided with valve component; Be provided with sliding bearing one between valve rod and the Stuffing box underpart, be provided with sliding bearing two between lower shaft lid and the ball core, be provided with filling system between valve rod and the Stuffing box upper end.
The surface of contact of valve seat and ball core all scribbles the WC-Co-Cr powder.
Sliding bearing one is carbon graphite bearing with sliding bearing two.
Gasket seal is made up of 316L and Expanded graphite.
Filling system is made up of annular Expanded graphite and tapered collar wire.
Beneficial effect of the present invention: reasonable in design, good seal performance, the spring long service life is rationally utilized self oiling bearing, and is safe and reliable.
