Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention makees further detailed
Description.Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
As shown in figure 1, a kind of ceramic tapered plug valve, including valve body 1, the middle part of the valve body 1
Fluid passage 2 provided with left and right insertion, the inwall of fluid passage 2 is provided with latus rectum earthenware 3,
The top of valve body 1 provided with downwards extension and with the bellmouth 4 of the insertion of latus rectum earthenware 3, cone
It is provided with shape hole 4 on conic ceramic plug 5, the side wall of conic ceramic plug 5 and is transversely provided with flowing hole
6, the top of bellmouth 4 is fixed in bonnet 8, the top end face of bonnet 8 by bonnet bolt 7
Portion is interspersed with the valve rod 9 being fixedly connected with conic ceramic plug 5, the top connection handle of valve rod 9
10, the hollow bolt 11 being connected by screw thread with bonnet 8 is arranged with the outer wall of valve rod 9,
Spring 12, the bottom of spring 12 are arranged with the outer wall of valve rod 9 of the bottom part down of hollow bolt 11
End is resisted against on the top end face of conic ceramic plug 5, and the top of spring 12 is resisted against hollow bolt
On 11 bottom face.
Gold is arranged with the ceramic tapered plug valve of the present invention, the top outer wall of the conic ceramic plug 5
Belong to cranse 13, metal cranse 13 is used for ensureing conic ceramic plug 5 when being rotated by valve rod 9 not
Can be by squeeze crack, also for the service life of extension conic ceramic plug 5.
Provided with square in the middle part of the ceramic tapered plug valve of the present invention, the top end face of the conic ceramic plug 5
Groove, the bottom of valve rod 9 is provided with the square spigot 14 being fixed in square groove.
Asbestos pad 15 is lined with the ceramic tapered plug valve of the present invention, the bottom face of the bonnet 8.
The contact position of the ceramic tapered plug valve of the present invention, the hollow bolt 11 and valve rod 9 passes through close
Seal 16 is sealed.
The ceramic tapered plug valve of the present invention is when specifically used, due to conic ceramic plug and latus rectum ceramics
Pipe is ceramic component, so abrasion is had after a long time use, this two parts meeting after abrasion
There is poorly sealed phenomenon, therefore this valve installs a spring on the top of conic ceramic plug,
There is an adjustable hollow bolt on the top of spring, pass through screw thread between hollow bolt and bonnet
Connection, when conic ceramic plug and the latus rectum earthenware poorly sealed phenomenon of generation, regulation is empty downwards
Heart bolt, spring is downward always for extruding taper ceramic plug, conic ceramic plug is made pottery with latus rectum
Porcelain tube keeps sealing state, the flowing hole of the two-part latus rectum of latus rectum earthenware and conic ceramic plug
Latus rectum is equally big.When three latus rectums are consistent valve for open, when conic ceramic plug latus rectum not
Valve is closing when consistent with the latus rectum of latus rectum earthenware.Therefore, this valve on pipeline without installation
Direction.The material of valve body and bonnet can be cast iron, spheroidal graphite cast-iron, casting steel or stainless steel, connect
Form is connect to connect for screwed flange.It is 0.25MPa-40MPa to be applicable nominal pressure.This valve is outstanding
