Description

Technical Field

[0001] The utility model relates to the technical field of cylinders, and more specifically to a cylinder-driven pneumatic valve component. Background Art

[0002] A cylinder-driven pneumatic valve is a valve driven by compressed air. It is usually composed of a pneumatic control system and a valve body. The pneumatic control system is used to control the movement of the valve core, thereby controlling the opening and closing of the valve.

[0003] For example, a pneumatic valve disclosed in CN219035737U has the following technical solutions: it comprises a tube body, a pneumatic cylinder body is mounted on the upper side of the tube body, a transmission rod in the pneumatic cylinder body extends through the outside of the pneumatic cylinder body, an angle limiter is arranged on the upper side of the pneumatic cylinder body, and the angle limiter is used to limit the rotation angle of the transmission rod; the rotation of the transmission rod is mainly blocked by a limit block, so that, for example, the rotation angle of the transmission rod can be controlled, and the rotation angle of the ball is correspondingly limited, so that rapid and accurate control of various flow rates can be achieved, and compared with the control through the air supply amount, the inertia effect is effectively reduced, so that the opening amplitude can be accurately controlled, and the accuracy of flow control is improved.

[0004] The above-mentioned cylinder-driven pneumatic valve assembly still has certain shortcomings: after long-term use, scale will appear on the inner wall of the valve body of the cylinder-driven pneumatic valve assembly. Once too much scale accumulates, it will affect the flow of the cylinder-driven pneumatic valve assembly. Therefore, it is necessary to provide a cylinder-driven pneumatic valve assembly.

[0007] The descaling assembly includes a first mounting ring and a first hydraulic telescopic rod, the side wall of the first mounting ring is detachably mounted with three first hydraulic telescopic rods in a circular array, and the outer surface of the first mounting ring is connected to one side of the inner wall of the connecting pipe.

[0008] Wherein, a descaling scraper is detachably mounted on one end of the first hydraulic telescopic rod, and the extension length of the first hydraulic telescopic rod is greater than the length of the connecting pipe.

[0009] The outer surface of the descaling scraper is adapted to the interior of the connecting pipe, and the cross-sectional area of ​​the descaling scraper is the same as the cross-sectional area of ​​the first mounting ring.

[0010] Wherein, the anti-falling component includes a second mounting ring and connecting bolts, the front side of the second mounting ring is symmetrically and detachably mounted with connecting bolts along the center, and one end of the connecting bolts is connected to the inside of the connecting nut through the second mounting ring.

[0011] Wherein, two second hydraulic telescopic rods are detachably mounted on the front side of the second mounting ring symmetrically along the center, and a third mounting ring is detachably mounted on one end of the second hydraulic telescopic rod.

[0012] Among them, four third hydraulic telescopic rods are detachably installed in a circular array inside the third mounting ring, and an arc-shaped fastening pad is detachably installed at the bottom end of the third hydraulic telescopic rod.

When scale appears inside the connecting pipe, the first hydraulic telescopic rod inside the descaling assembly is started to drive the descaling scraper to move. Because the outer surface of the descaling scraper fits the inner wall of the connecting pipe, the scale appearing on the inner wall of the connecting pipe can be cleaned while the descaling scraper moves. In addition, the first hydraulic telescopic rod has the function of automatic extension and retraction, so it can also reduce the workload of the staff, thereby enhancing the practicability of the device.
