Abstract
The utility model relates to a ceramic seal dome valve, include: a valve core and a valve cover; the valve core is sleeved with a ceramic ring, and the outer wall of the ceramic ring is provided with a first wedge-shaped surface; a gland is fixed at the top of the valve core, and a ceramic ring is fixed between the gland and the valve core; a second ceramic ring is fixedly arranged at the bottom in the valve cover; a second wedge-shaped surface matched with the first wedge-shaped surface is arranged on the side edge of the upper bottom of the second ceramic ring; the mode of ceramic material sealing is adopted in the device, when the valve core and the valve cover are close to each other, the first wedge-shaped surface of the ceramic ring is attached to the second wedge-shaped surface of the second ceramic ring, so that mutual sealing is realized, the abrasion loss of the ceramic material is small, and the sealing performance of the valve core and the valve cover in a closed state is improved.
Description
Technical Field
The utility model relates to a ball valve specifically is a ceramic seal dome valve.
Background
In the working process of the ball valve, the valve core and the valve cover need to be switched between an opening state and a closing state; when the valve core and the valve cover are in a closed state, high sealing performance between the valve core and the valve cover needs to be ensured; the existing mode is realized through a sealing ring, when the sealing ring is used for a long time, the sealing ring is aged or abraded, so that the sealing performance is reduced;
in conclusion, how to improve the sealing performance of the valve core and the valve cover in a closed state becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to improve the sealing performance of the valve core and the valve cover in a closed state;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a ceramic seal dome valve, include: a valve core and a valve cover; the valve core is sleeved with a ceramic ring, and the outer wall of the ceramic ring is provided with a first wedge-shaped surface; a gland is fixed at the top of the valve core, and a ceramic ring is fixed between the gland and the valve core; a second ceramic ring is fixedly arranged at the bottom in the valve cover; a second wedge-shaped surface matched with the first wedge-shaped surface is arranged on the side edge of the upper bottom of the second ceramic ring;
in the scheme, the ceramic material is abraded, so that the abrasion loss in the sealing process is small, and the service life of the device is prolonged; specifically, when the valve core and the valve cover are close to each other, a first wedge-shaped surface of the ceramic ring and a second wedge-shaped surface of the second ceramic ring are attached to each other, so that mutual sealing is realized; the gland is used for fixing the ceramic ring between the valve core and the valve cover, so that the ceramic ring is prevented from falling off in the sealing process.
In order to explain how the ceramic ring is arranged between the gland and the valve core, the utility model adopts the valve core to be provided with a first annular gap for placing the ceramic ring; a second annular gap which is contacted with the upper end surface of the ceramic ring is arranged on the gland;
that is to say, the difference in height between second annular breach and the first annular breach equals the height of ceramic ring, sets up first, annular breach and also can reduce the height of case and gland.
The utility model has the advantages that: the utility model relates to a ceramic seal calotte valve adopts the sealed mode of ceramic material in this device, when case, valve gap are close to each other, the first wedge face of pottery ring and the second wedge face of second pottery ring laminate each other to realized mutual sealing, ceramic material wearing and tearing volume is little, just improves the sealing performance of case, valve gap when the closure state.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is an exploded view of the valve core, the gland and the ceramic ring of the present invention;
in the figure: 1-valve core, 2-valve cover, 3-ceramic ring, 4-first wedge surface, 5-gland, 6-second ceramic ring, 7-second wedge surface, 8-first annular gap, 9-second annular gap.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the present invention is a ceramic seal dome valve comprising: a valve core 1 and a valve cover 2; a ceramic ring 3 is sleeved on the valve core 1, and the outer wall of the ceramic ring 3 is provided with a first wedge-shaped surface 4; a gland 5 is fixed on the top of the valve core 1, and a ceramic ring 3 is fixed between the gland 5 and the valve core 1; a second ceramic ring 6 is fixedly arranged at the bottom in the valve cover 2; the side edge of the upper bottom of the second ceramic ring 6 is provided with a second wedge-shaped surface 7 matched with the first wedge-shaped surface 4;
in the scheme, the ceramic material is abraded, so that the abrasion loss in the sealing process is small, and the service life of the device is prolonged; specifically, when the valve core and the valve cover are close to each other, a first wedge-shaped surface of the ceramic ring and a second wedge-shaped surface of the second ceramic ring are attached to each other, so that mutual sealing is realized; the gland is used for fixing the ceramic ring between the valve core and the valve cover, so that the ceramic ring is prevented from falling off in the sealing process.
As shown in fig. 1-2, in order to illustrate how the ceramic ring is installed between the gland and the valve core, the present invention adopts the valve core 1 to be provided with a first annular notch 8 for placing the ceramic ring 3; a second annular gap 9 which is contacted with the upper end surface of the ceramic ring 3 is arranged on the gland 5;
that is to say, the difference in height between second annular breach and the first annular breach equals the height of ceramic ring, sets up first, annular breach and also can reduce the height of case and gland.
The utility model relates to a ceramic seal calotte valve adopts the sealed mode of ceramic material in this device, when case, valve gap are close to each other, the first wedge face of pottery ring and the second wedge face of second pottery ring laminate each other to realized mutual sealing, ceramic material wearing and tearing volume is little, has just improved the sealing performance of case, valve gap when the closure state.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
