Description

TECHNICAL FIELD

[0001] The utility model relates to valve technical field, concretely relates to a pressure pipeline valve. BACKGROUND

[0002] Valves are control elements, and their main functions are to isolate equipment and piping systems, regulate flow, prevent backflow, regulate and drain pressure.

[0003] The Chinese patent document with the authorized announcement number CN219317672U discloses a ball valve for pressure pipeline, when people want to switch the ball valve from the closed state to the open state, people can first rotate the swivel ring to rotate the swivel plate by a certain angle through the swivel ring, so that the connecting pipe can be synchronously rotated, the fixed bolt on the connecting flange two and the connecting flange one can position the sliding groove on the swivel plate, when one side of the sliding groove contacts the fixed bolt and is rotated to the other side, the through hole on the connecting pipe can close or flow through the communication conduit, rotating the swivel ring makes the through hole correspond to the communication conduit, so that the water flow in the water inlet pipe can enter the water outlet pipe through the communication conduit, realizing the flow distribution of the water flow, so as to effectively reduce the opening difficulty of the ball valve, after the ball valve is opened, people can rotate the swivel ring in the opposite direction to rotate the connecting pipe by a certain angle, so that the communication conduit becomes a closed state, through the flow distribution of the water flow before opening the ball valve, the pressure of the water flow on the sealing valve core can be greatly reduced, the opening work of the sealing valve core is more relaxed, the friction loss between the valve core seat and the sealing valve core can be effectively reduced, and the service life of the ball valve can be effectively prolonged.

A through hole 6 is provided on the outer circular surface of the connecting pipe 2 and at the bottom end of the connecting pipe 2; wherein, the end of the connecting pipe 2 has a connecting flange.

[0028] The mounting housing 3 is installed directly below the valve body 1 and the two connecting pipes 2. An adjusting block 7 is provided on the inner side of the mounting housing 3 for moving up and down along the inner wall of the mounting housing 3 during use.

[0029] The transmission component is installed at the bottom of the mounting housing 3 and extends to the inside of the mounting housing 3 to connect with the adjusting block 7. It is also connected to an external drive device to move the adjusting block 7 inside the mounting housing 3. The external drive device can be a motor or a wheel with an anti-rotation structure.
