[0002] The background technique of the adjustable flange ball valve involves the development process of valve technology, especially its application in the field of industrial pipeline control. In industrial pipeline systems, gate valves and globe valves are mainly used for fluid control, but these valves have relatively large fluid resistance and are not flexible enough in operation. With the development of technology, ball valves have been gradually widely adopted due to their simple structure, small fluid resistance, and rapid opening and closing. Initially, ball valves were mainly fully open or fully closed and could not adjust the flow rate. To meet the demand for flow rate adjustment in industrial processes, adjustable ball valves were developed, that is, by rotating the ball to partially open or close the valve to control the flow rate.

Then, when it is necessary to open the ball valve at different pipelines, it is rather inconvenient, so the operation is relatively complex. Therefore, it does not meet the existing requirements. For this reason, we propose an adjustable flange ball valve. Content of the Utility Model

The purpose of this embodiment is to facilitate the solution of the problem in the prior art that in the use of ball valves, most are adjusted by the master control during the use process. Then, when it is necessary to open the ball valve at different pipelines, it is rather inconvenient, so the operation is relatively complicated. Please refer to Figures 1-6 , an adjustable flange ball valve, including a ball valve body 130, a handle 110 is installed above the ball valve body 130, a connecting pipe 120 is snap-connected to the side of the ball valve body 130 through a snap-fit component 360, a flow channel 140 is opened in the middle of the connecting pipe 120, a limiting component 350 is arranged in the middle of the flow channel 140, an installation groove 150 is opened on one side of the connecting pipe 120, a sealing block 170 is fixedly installed on the other side of the connecting pipe 120, and a card slot 160 is opened on the side of the sealing block 170.

[0025] A moving groove 280 is arranged on the side of the card slot 160, and the moving groove 280 is in contact connection with the limiting component 350. The limiting component 350 includes a rotating shaft 180 installed in the middle of the installation groove 150, a baffle 190 is fixedly connected to the side of the rotating shaft 180, a sealing strip 200 is fixedly connected to the side of the baffle 190, the sealing strip 200 is in contact connection with the sealing block 170, a connecting shaft 270 is fixedly installed on the side of the baffle 190, a connecting rod 230 is rotatably installed on the side of the connecting shaft 270, a telescopic groove 240 is opened in the middle of the connecting rod 230, and a compression spring 250 is installed in the middle of the telescopic groove 240.

[0026] The ball valve body 130 is the core part of the ball valve, which contains a rotatable sphere inside. The rotation of the sphere can control the opening and closing of the flow channel 140. The handle 110 is installed above the ball valve body 130. By rotating the handle 110, the rotation of the sphere can be controlled, thereby realizing the opening and closing of the flow channel 140. The connecting pipe 120 is connected to the ball valve body 130 through the snap-fit component 360. The flow channel 140 is located in the middle of the connecting pipe 120 and is the channel for the medium to flow. The limiting component 350 is arranged in the middle of the flow channel 140 to ensure the correct alignment and fixation of the connecting pipe 120 and the ball valve body 130. The sealing block 170 is fixedly installed on one side of the connecting pipe 120 to seal the connection part and prevent the medium from leaking. The sealing strip 200 is in contact connection with the sealing block 170, further enhancing the sealing effect.

[0027] The limiting component 350 includes a rotating shaft 180, a baffle 190, and a sealing strip 200. By contacting and connecting with the side of the clamping groove 160 of the sealing block 170 through the moving groove 280, the adjustment of the position of the sealing block 170 is realized. The design of the compression spring 250 and the extrusion block 260 is used to maintain the pressure between the sealing block 170 and the connecting pipe 120 to ensure the sealing effect. When the compression spring 250 is compressed, the extrusion block 260 will push the sealing block 170 tightly against the connecting pipe 120. The clamping component 360 includes a connecting block 290, a clamping groove 300, and a limiting spring 310, which is used to fix the connecting pipe 120 and the ball valve body 130.

The ball valve body 130 and the connecting pipe 120 are fixed through the expansion bolt 340 to ensure a stable connection. The position of the sealing block 170 is adjusted through the moving groove 280 and the limiting component 350 to adapt to pipe connections of different sizes. By rotating the handle 110, the sphere inside the ball valve rotates accordingly, thereby opening or closing the flow channel 140 to control the flow of the medium. During the operation of the ball valve, the compression spring 250 maintains the continuous pressure of the extrusion block 260 on the sealing block 170 to ensure the sealing performance of the connection part. If components such as the sealing block 170 need to be maintained or replaced, the ball valve body 130 can be opened by disassembling the clamping component 360 and the expansion bolt 340.

[0029] In this embodiment: Through the setting of the handle 110, the operator can conveniently operate the opening and closing of the ball valve through the handle 110, improving the convenience of operation. Through the setting of the limiting component 350 and the moving groove 280, the position of the connecting pipe 120 can be adjusted to adapt to pipe connections of different sizes, improving the adaptability of the ball valve. Through the setting of the sealing block 170 and the sealing strip 200, the sealing performance of the ball valve during connection is ensured, preventing medium leakage. The structure of the compression spring 250 and the extrusion block 260 can ensure that the sealing block 170 is always in close contact with the connecting pipe 120 during the use of the ball valve, further enhancing the sealing effect.
