Abstract
The invention discloses a kind of wear-resistant embedded ceramic ball valve in ball valve field, including valve body, sphere, airtight and watertight padding, gland, valve rod, transmission devices；The valve body includes left valve barrel, right valve barrel, and the left valve barrel is bolted with right valve barrel；It is provided with runner in the middle part of the sphere, the runner both sides are respectively equipped with import anti-wearing liner and outlet wear bushing, and the runner inner wall is embedded with wear-resistant corrosion-resistant ceramic；The valve stem equipment includes upper valve rod, lower valve rod, and the upper valve rod is connect with transmission device, and the upper valve rod is surrounded by airtight and watertight padding, gland.The configuration of the present invention is simple, runner abrasion is small, and ceramics are not easily broken, and service life is long.
Description
Technical field
The present invention relates to block valve field, more particularly to a kind of wear-resistant embedded ceramic ball valve.
Background technology
Ceramic ball valve type currently on the market is more, but the wall thickness of ceramic member is thin, while ceramic material belongs to brittleness material
Material is likely to the ceramic trim caused by the factors such as fluid impurity, difference variation, abnormal operation are especially and collapses in actual use
It splits, cause media contact metal and corrodes quickly totally, to which failure causes to leak outside, influence production and even cause the accident.
Invention content
The object of the present invention is to provide a kind of not easy to wear, wear-resistant embedded ceramic ball valves with long service life.
The object of the present invention is achieved like this, a kind of wear-resistant embedded ceramic ball valve, including valve body, sphere, sealing
Filler, gland, valve rod, transmission device；The valve body includes left valve barrel, right valve barrel, and the left valve barrel passes through with right valve barrel
It is bolted；It is provided with runner in the middle part of the sphere, the runner both sides are respectively equipped with import anti-wearing liner and outlet wear bushing,
The runner inner wall is embedded with wear-resistant corrosion-resistant ceramic；The valve stem equipment includes upper valve rod, lower valve rod, the upper valve rod with pass
Dynamic device connection, the upper valve rod are surrounded by airtight and watertight padding, gland.
Compared with prior art, the invention has the beneficial effects that：Due in sphere inner wall embedded ceramic so that ceramics exist
It is not easily broken under the protection of ectosome；Since ceramics are in inner wall so that corrosive liquid cannot be in direct contact the metal material of ectosome
Matter avoids the aging of metal, increases the service life of valve body；Due to being provided with anti-wearing liner on the inside of runner so that in runner
Lateral wearing is smaller, can be protected using seal performance for a long time.
As the preferred embodiment of the present invention, the upper valve rod and lower valve rod are on the same axis.
As present invention further optimization scheme, the O-ring of guaranteed leakproofness is set below the lower valve rod.
As present invention further optimization scheme, the transmission device can be changed to it is pneumatic, surge, be electronic etc..
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Wherein, 1 valve body, 2 spheres, 3 airtight and watertight paddings, 4 glands, 5 transmission devices, 6 left valve barrels, 7 right valve barrels, 8 streams
Road, 9 import anti-wearing liners, 10 outlet wear bushings, 11 ceramics, 12 upper valve rods, 13 lower valve rods, 14 O-rings.
Specific implementation mode
As shown in Figure 1, a kind of wear-resistant embedded ceramic ball valve, including valve body 1, sphere 2, airtight and watertight padding 3, gland
4, valve rod, transmission device 5；The valve body 1 includes left valve barrel 6, right valve barrel 7, and the left valve barrel 6 is connected with right valve barrel 7 by bolt
It connects；1 middle part of the sphere is provided with runner 8, and 8 both sides of the runner are respectively equipped with import anti-wearing liner 9 and outlet wear bushing 10,
8 inner wall of the runner is embedded with wear-resistant corrosion-resistant ceramic 11；The valve rod includes upper valve rod 12, lower valve rod 13, the upper valve rod
12 connect with transmission device 5, and the upper valve rod 12 is surrounded by airtight and watertight padding 3, gland 4.
Above-mentioned upper valve rod 12 and lower valve rod 13 are on the same axis.
The O-ring 14 of guaranteed leakproofness is arranged in 13 lower section of above-mentioned lower valve rod.
Above-mentioned transmission device 5 can be changed to it is pneumatic, surge, be electronic etc..
The operation principle of the present invention is described below：Sphere 2 is driven to rotate by transmission device 5,2 upper runner 8 of sphere and outside
When runner 8 is consistent, valve is opened, and drives sphere 2 again by transmission device 5 so that valve is closed.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing performing creative labour
A little to replace and deform, these are replaced and deformation is within the scope of the invention.
