This creation is about the field of pipe components and equipment, especially a ceramic ball valve.

Pipeline is an important equipment for conveying media and hydraulic and pneumatic control. Valves are commonly used in various pipelines to connect, close, and regulate the flow and pressure of pipelines to meet production needs. Among them, the ball valve is quick to open and close, easy to operate, and widely used. The ball valve generally comprises a valve body, a valve ball, a sealing assembly, a coupling assembly and the like, and a close fit between the components effectively controls the circulation of the pipeline fluid. During use, due to impurities in the fluid, especially fluids that are inherently mixed with impurities, the impact on the flow path, the ball, the valve seat, and the corrosion will destroy the original tight fit state, causing the valve ball to shift or Swinging causes the stem to be deformed, which has a large impact on the operation. The application of ceramic materials in ball valves can effectively improve the influence of corrosion, but the erosion of solid matter in the fluid will still cause the wear deformation of the valve seat and the valve ball. After a period of time, the valve ball will be deflected and cause The valve stem is deformed, which affects the normal opening and closing operation of the valve. Therefore, there is a need for a structure that can be operated without the valve ball being displaced after the valve ball or the valve seat is subjected to wear and deformation.

Therefore, in order to effectively solve the above problems, the purpose of the present invention is to provide a ceramic ball valve system to prevent the valve ball from being uncontrollable. In order to achieve the above object, the present invention provides a ceramic ball valve comprising: a valve body, a valve ball, a valve seat, a valve stem, and a support column, the valve ball being disposed in a cavity inside the valve body And a valve body is disposed inside the valve body, the valve seat is disposed below the cavity, a rubber gasket is disposed between the valve seat and the valve body; the support column is disposed at the valve seat Directly below, the support column includes a first pillar and a second pillar from top to bottom. The first pillar and the second pillar are connected to each other to form an inverted T-shaped structure, and the upper end of the first pillar extends through the valve. Inside the ball; the upper end of the valve ball is provided with a steering groove for operation control, the lower end of the valve stem is installed in the steering groove, and the upper end of the valve stem is connected with a handle, the valve seat includes a left valve seat and a right valve a seat, the left valve seat and the right valve seat are connected via a screw. In one embodiment, the first pillar and the second pillar are cylindrical structures, and the diameter of the first pillar is smaller than the diameter of the second pillar, and the length of the first pillar is higher than the length of the second pillar. In one embodiment, the bottom of the valve ball is provided with a support slot corresponding to the diameter of the first leg, and the valve ball is sleeved on the first pillar by the support slot. In one embodiment, the valve ball is disposed in a hollow spherical structure that is bilaterally symmetrical and defines a circular through hole having a diameter smaller than a diameter of the ball valve.

The first embodiment is shown in the first figure. A ceramic ball valve includes a valve body 5, a valve ball 2, a valve seat 3, a valve stem 6, and a support column 1. The valve ball 2 is disposed on the valve body. a valve body 5 is disposed in a cavity inside the valve body 5, and a valve passage 3 is disposed under the cavity. A rubber gasket is disposed on the valve seat 3 and the valve body 5. The support column 1 is disposed directly below the valve seat 3, and the support column 1 includes a first pillar a and a second pillar b in order from top to bottom. The first pillar a and the second pillar b are connected to each other. Forming an inverted T-shaped structure, the upper end of the first pillar a extends through the valve ball 2; the upper end of the valve ball 2 is provided with a steering groove for operation control, and the lower end of the valve stem 6 is installed in the steering groove The upper end of the valve stem 6 is connected to a handle 8. The valve seat 3 is embodied as a left valve seat and a right valve seat. The left valve seat and the right valve seat are connected via a screw 7. The handle 8 controls the rotation angle of the steering groove through the valve stem 6, thereby achieving the purpose of controlling the flow of the fluid in the valve body 5. A support groove is provided in the valve body 5 directly below the valve ball 2 for mounting the support column 1. When the valve ball 2 rotates, it is limited to a small space in which the valve seat 3 and the valve stem 6 and the support column 1 are restricted by the clearance. When the valve seat 3 is worn, the valve ball 2 is common to the valve stem 6 and the support column 1. Under the action, the problem of the offset does not occur, and the valve ball 2 is not broken due to the asymmetry of the force, and the uncontrollable problem caused by the deviation of the valve ball 2 is also avoided. The first pillar a and the second pillar b are cylindrical structures, and the diameter of the first pillar a is smaller than the diameter of the second pillar b, and the length of the first pillar a is higher than that of the second pillar b. length. The first pillar a acts as a fulcrum, so that the position of the valve ball 2 is not displaced during the clockwise or counterclockwise rotation, and is in a stable state in the vertical direction. The bottom of the valve ball 2 is provided with a support slot corresponding to the diameter of the first post a, and the valve ball 2 is sleeved on the first post a by the support slot. The valve ball 2 is disposed in a hollow spherical structure which is bilaterally symmetrical and defines a circular through hole having a diameter smaller than a diameter of the ball valve. The specific implementation controls the rotation of the valve stem 6 via the handle 8 to drive the valve ball 2 to rotate. When the ceramic ball valve needs to be opened, the valve ball 2 is rotated to form a passage for the circular through hole on the valve ball 2. The fluid passage 4 in the valve body 5 is at the same horizontal line; when the ceramic ball valve needs to be closed, the valve ball 2 is rotated to make the passage formed by the circular through hole on the valve ball 2 and the fluid in the valve body 5 Channel 4 is in a vertical state. Second Embodiment The present embodiment is substantially the same as the first embodiment except that the valve body 5 is of a unitary structure, and the rubber gasket between the valve seat 3 and the valve body 5 is as shown in FIG. The rubber gasket includes a top spacer 9 disposed above and below, and an airbag 10 and a lower gasket 11 connected together. An intermediate portion of the airbag 10 is disposed in a longitudinal direction along a longitudinal direction. Elastic rubber ring arranged in a circle. The rubber gasket exerts a sealing effect, and the double gasket structure of the upper gasket 9 and the lower gasket 11 has a certain elastic deformation effect in the middle, and the elastic rubber ring in the interior plays during the compression process. The role of the support increases the contact area with the airbag 10 at the same time, effectively controlling the elastic deformation of the airbag 10, and prolonging the service life. In summary, the ceramic ball valve of the present invention controls the rotation of the valve ball 3 through the valve stem 6, thereby controlling the opening and closing of the ceramic ball valve. Compared with the conventional valve, the present invention is provided at the lower end of the valve ball 2. The support column 1 can effectively prevent the displacement of the valve 2 ball. Even if the valve ball 2 and/or the valve seat 3 are worn and deformed, the valve ball 2 will not be biased under the joint action of the valve stem 6 and the support column 1, and can still be manipulated.
