The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Examples
As shown in fig. 1, a pressure stabilizing control ball valve comprises a valve body 1, wherein two ends of the valve body 1 comprise an inflow channel 11 and an outflow channel 12, and a valve cavity 13 is arranged between the inflow channel 11 and the outflow channel 12; a valve ball body 130 for controlling opening and closing is arranged in the valve cavity 13, and a pressure stabilizing cavity 14 is also arranged in the valve body 1; as shown in fig. 2, the pressure stabilizing cavity 14 is located below the valve ball 130, the pressure stabilizing cavity 14 is composed of an upper cavity and a lower cavity which are communicated with each other, the upper cavity and the lower cavity are both cylindrical, a pressure stabilizing piston 141 is arranged in the upper cavity, the upper end of the pressure stabilizing piston 141 is fixedly connected with a valve seat 142, the valve seat 142 penetrates through the upper part of the upper cavity, and a sealing ring is arranged at the joint of the valve seat 142 and the top of the upper cavity; a pressure-stabilizing valve plate 143 for regulating the flow rate of the fluid in the inflow channel 11 is connected above the valve seat 142, and the pressure-stabilizing valve plate 143 is located in the inflow channel 11.
The lower cavity is communicated with the inflow channel 11 through a conduit 140, a pressure-stabilizing adjusting handle 144 is arranged below the lower cavity, and the pressure-stabilizing adjusting handle 144 is abutted against the lower part of the pressure-stabilizing piston 141 through a pressure-stabilizing adjusting rod 1440 penetrating through the lower cavity; a sealing ring is arranged at the joint of the pressure-stabilizing adjusting rod 1440 and the bottom of the lower cavity.
Wherein, the surface of the pressure-stabilizing adjusting rod 1440 is provided with external threads, and the joint of the pressure-stabilizing adjusting rod 1440 and the valve body 1 is provided with an adjusting ring 1441 containing internal threads.
In the upper cavity, a pressure stabilizing medium is arranged above the pressure stabilizing piston 141. The pressure stabilizing medium is liquid fluid or gaseous fluid.
In this embodiment, a valve passage for fluid to pass through is provided in the valve ball 130, and the valve ball 130 and the upper and lower ends of the valve cavity 13 are connected by an upper bearing 1310 and a lower bearing 1300, respectively.

The top of the valve ball 130 is fixedly connected with a valve rod 131, and an opening and closing valve handle 132 is connected above the valve rod 131.
When the control ball valve is used, an operator rotates the open-close valve handle 132 to enable the valve passage in the valve ball body 130 to be communicated with the inflow passage 11 and the outflow passage 12, so as to open the valve body 1. When the fluid flux in the inflow channel 11 is abnormally increased, the air pressure in the inflow channel 11 is increased, which further causes the air pressure in the lower cavity in the pressure stabilizing cavity 14 to be increased, and after the air pressure in the lower cavity is increased, the pressure stabilizing piston 141 is lifted, and the pressure stabilizing valve plate 143 in the inflow channel 11 is lifted through the valve seat 142; after the pressure stabilizing valve plate 143 is lifted, the opening of the inflow channel 11 is reduced, the flux of the fluid flowing into the inflow channel 11 is obviously reduced, and pressure stabilizing adjustment is realized.
