Abstract
The utility model discloses a ceramic regulating ball valve, comprising a metal valve body, a ceramic regulating plate, a valve core, a valve rod and a valve rod drive device, wherein the ceramic regulating ball valve is characterized in that the valve core comprises a metal turning block and a ceramic sealing piece; the metal turning block and the valve rod are extended into one end inside the metal valve body and fixedly connected; the ceramic sealing piece is fixed on the metal turning block; and the ceramic sealing piece and the ceramic regulating plate form a spherical sealing cooperation. Since the valve rod and the metal turning block are fixedly connected, the metal turning block is fixed with a ceramic sealing piece again, and the ceramic regulating ball valve effectively conquers the problem that the known ceramic sphere valve core is easy to break when turned.
Description
Technical field
The utility model relates to a kind of ceramic regulation globe valve, and particularly a kind of spool is the ceramic regulation globe valve of non-rounding type spheroid.
Background technique
Ceramic ball valve has resistance to chemical attack, many-sided characteristic such as wear-resistant, high temperature resistant, is widely used in fields such as chemical industry, pharmacy, incineration of waste, flue gas desulfurization.Existing ceramic ball valve structure generally comprises metal valve body, ceramic regulator plate, spheres of ceramic spool, valve rod and drive unit, metal valve body connects two sections fluid lines, the pottery regulator plate is located in the metal valve body, the spheres of ceramic spool is located between the two ceramic regulator plates rotationally, valve rod one end is connected with on the spheres of ceramic spool, and the other end extends to outside the metal valve body and with drive unit and links to each other.Existing spool is the spheres of ceramic spool, and the spheroid spool is fixedlyed connected with metal valve stem again, and when valve rod drove the spool rotation, spheres of ceramic spool and valve rod joint were subjected to bigger twisting force, and is therefore broken easily.
The model utility content
The purpose of this utility model is to overcome above technological deficiency, and a kind of new ceramics modulating valve is provided, breakable problem when it can effectively overcome known ceramics ball valve spheres of ceramic valve core rotation.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of ceramic regulation globe valve, comprise metal valve body, ceramic regulator plate, spool, valve rod and valve rod driving device, it is characterized in that: described spool comprises metal moving block and ceramic seal gasket, the metal moving block is fixedlyed connected with the end in valve rod stretches into metal valve body, ceramic seal gasket is fixed on the metal moving block, and ceramic seal gasket forms ball face sealing with ceramic regulator plate and cooperates.
The utility model further is set to: the runner mouth on the ceramic regulator plate is fan-shaped runner mouth.
The beneficial effects of the utility model are: because valve rod fixedlys connected with the metal moving block, the metal moving block is fixed a ceramic seal gasket again, so valve rod is when driving the rotation of metal moving block, breakable problem when having overcome existing spheres of ceramic valve core rotation.Runner mouth on the ceramic in addition regulator plate is the flow through flow of medium of fan-shaped easy adjusting.
Further describe below in conjunction with accompanying drawing and embodiment

Embodiment
As shown in Figure 1, a kind of ceramic regulation globe valve comprises metal valve body 8, ceramic regulator plate 4, spool, valve rod 1 and valve rod 1 drive unit.
Metal valve body 8 general shape are the cylinder of a horizontal drain, and two end periphery stretches out to form respectively bulge loop 3,9 is installed, and metal valve body 8 can be fixedlyed connected with two segment pipes by bulge loop 3,9 is installed.Valve rod 1 one ends stretch out metal valve body 8 and are connected with drive unit, and the other end stretches into and connects a metal moving block 6 in the metal valve body 8, and this metal moving block 6 is inlayed a ceramic seal gasket 2, and these ceramic seal gasket 2 one sides are arc surface.Pottery regulator plate 4 is located in the metal valve body 8, and it is the circular arc concave surface with ceramic seal gasket 2 relative one sides, and ceramic seal gasket 2 combines the spool that formation one is roughly the hemisphere shape with metal valve body 8, and ceramic seal gasket 2 forms rotary seals with ceramic regulator plate 4 and cooperates.Metal valve body 8 internal channels cover one deck ceramic protective layer 10, and the part that metal moving block 6 contacts with medium also sprays one deck ceramic coating, and purpose is to prevent that metal valve body 8 and metal moving block 6 are by dielectric corrosion.
Runner mouth 5 on the utility model pottery regulator plate 4 is fan-shaped, shown in Fig. 2 to 4, discloses three kinds of fan-shaped runner mouths.The utility model pottery regulator plate 4 adopts the purpose of fan-shaped runner mouth to be the convenient flow of regulating the medium of flowing through.
Aforesaid drive unit is a manual operating device, and this manual operating device is provided with a spanner 7, and spanner 7 is fixedlyed connected with the end that valve rod 1 stretches out metal valve body 8, and spanner 7 drives valve rod 1 and rotates.Can certainly adopt devices such as pneumatic, electronic as required.
By foregoing description as can be known, valve rod 1 of the present utility model is connected with metal moving block 6, and ceramic seal gasket 2 is fixing with metal moving block 6 again, so is difficult for during valve core rotation broken.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited in this, and all unsubstantialities that utilizes this design that the utility model is carried out are changed, and all should belong to the behavior of invading the utility model protection domain.
