The valve rod penetrates through the valve body, and is connected on the connecting seat. Since the stainless steel connecting seat adopts a directly-sintering mode to fixedly connect with the ceramic valve core, the valve core has long service life and high impact-resistance property.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of ceramic ball valve that partly serves as a contrast.
Background technique
Because ball valve can be in order to fluid flow in the control valve, so application area is very extensive, for example be applied in food industry, pharmaceuticals industry and give birth to skilled worker's industry etc.Along with the technical development of ball valve, a kind of ceramic ball valve that partly serves as a contrast has just appearred on the market, and it comprises a valve body, a valve gap, second ring ceramic valve seat, a ceramic valve core and a valve rod.The affixed valve body of this valve bonnet seal, and, all being provided with a horizontal through hole within this valve body and the valve gap, those horizontal through hole are coaxial docking and form penetration hole; This two ceramic valve seat pad is located within the penetration hole; This ceramic valve core hermetically, can be located between two ceramic valve seats rotationally and control the ball valve fluid flow; This valve rod passes valve body and is connected spool.Because valve rod is metal material, spool is a ceramic material, so this valve rod and spool is directly affixed will have following deficiency: the impact resistance of spool is low, and working life is short.
The model utility content
The utility model provides a kind of ceramic ball valve that partly serves as a contrast, the deficiency that its impact resistance that partly serves as a contrast the existing spool of ceramic ball valve that has overcome background technique is low, working life is short.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of ceramic ball valve that partly serves as a contrast, it comprises:
One valve body and a valve gap, the affixed valve body of this valve bonnet seal, and, all being provided with a horizontal through hole within this valve body and the valve gap, those horizontal through hole are coaxial docking and form penetration hole;
Two linings are located at the ring-shaped pottery valve seat within the penetration hole;
The ceramic valve core of one control flow rate, it hermetically, can be located at rotationally between two ceramic valve seats, and this ceramic valve core is provided with one and adopts direct sintering mode and the affixed stainless steel connecting base of ceramic valve core; And
One valve rod, it passes valve body and is connected connecting base.
This valve body offers the attachment hole that runs through inside and outside, and this valve rod passes attachment hole, and this valve rod is provided with:
One is convexly equipped with out the convex shoulder of valve rod external cylindrical surface;
One socket valve rod, by being located at the thrust washer on the convex shoulder, it is positioned within the attachment hole;
One socket valve rod, by being located at the blast ring on the thrust washer, it is screwed onto within the attachment hole;
One filler, it is filled out between the attachment hole and valve rod that is located on the blast ring;
The Gland of one socket valve rod, its lid is located on the filler; And
The location piece of one fixedly sleeved valve rod, it is positioned on the Gland.
Offer a penetration hole on this location piece, offer one on this Gland and open a lockhole and a pass obturator hernia; Other sets unlatching lockhole or pass obturator hernia that a lock pin passes the penetration hole of location piece and selects to insert Gland.
Be provided with one first positioning step within the through hole of this valve gap, the vertical plane of this first positioning step is abutted against mutually with a ceramic valve seat exterior edge face, and, also be provided with a seal ring between them;
Be provided with one second positioning step within the through hole of this valve body, the vertical plane of this second positioning step is abutted against mutually with another ceramic valve seat exterior edge face, and, also be provided with a seal ring between them.
No gap cooperates between the connection end face of this valve gap and the connection end face of valve body, and other sets affixed valve gap of screw and valve body.
The technical program is compared with background technique: because stainless steel connecting base employing direct sintering mode and ceramic valve core are affixed, by connecting base valve rod and spool are linked together, so long service life of this spool, the impact resistance height, affixed solid and reliable between this spool and the connecting base, easy to process fast.Because the material of this ceramic valve seat and ceramic valve core all is a pottery, therefore be half lining ceramic ball valve.Because thrust washer is by on the convex shoulder that is located at valve rod, blast ring is by being located on the thrust washer, and the attachment hole of blast ring and valve body is spirally connected fixing, so can prevent that valve rod from producing the Safety performance height because of body cavity pressure is excessive.Because the metal of valve gap connects the metal of end face and valve body and connects no gap cooperation between the end face, therefore can avoid liquid leakage, avoids locking phenomenon occurring between valve seat and the spool.Owing to be provided with the locking framework of selecting locking ball valve conducting or locking ball valve to close between location piece and the Gland, therefore can avoid misoperation.
