Description

Technical Field

[0001] This utility model relates to the field of triple offset valve technology, specifically an improved triple offset valve. Background Technology

[0002] A triple-eccentric valve is a type of valve in which the valve stem axis is offset from both the center of the disc and the center of the body, and the rotation axis of the valve seat is at a certain angle to the axis of the valve body passage.

[0003] The prior art patent document CN205639645U discloses a triple eccentric butterfly valve. The conical sealing pair, the corresponding cone angle β, and the angle α between the center line of the cone and the center line of the valve body ensure that the two sealing surfaces of the sealing pair disengage within a very small turning range during opening or closing, and there is almost no friction between the two sealing surfaces. After the valve is closed, the torque applied to the valve shaft generates a suitable sealing specific pressure on the sealing pair, ensuring the tight closure of the valve. The angle range of the conical sealing pair and the corresponding cone angle β, as well as the angle range of the angle α between the center line of the cone and the center line of the valve body, simultaneously meet the optimization requirements of the sealing pair size of commonly used butterfly valve specifications. The clamping support is annular, and the outer ring of the annular clamping support is provided with an installation step, which is inserted into the support installation groove in the valve body hole. In this embodiment, the clamping support is installed in the support mounting groove inside the valve body hole. Its structure is compact and does not increase the overall size of the butterfly valve. The clamping support consists of four ring-shaped pieces, two of which are bow-shaped. This embodiment provides a split structure for the clamping support, ensuring that it can be easily and quickly installed in the support mounting groove inside the valve body hole. An eccentricity A is provided between the centerline of the valve shaft and the centerline of the valve body hole. The centerline of the conical surface and the centerline of the valve body hole are in the same plane, which is perpendicular to the centerline of the valve shaft. The apex of the conical surface and the centerline of the valve shaft are on the same side of the centerline of the valve body hole. This embodiment further ensures that the friction between the sealing pairs is within the minimum angular range during the rotation and opening / closing of the valve plate, thus optimizing the valve's sealing effect and further guaranteeing its service life.

[0004] However, due to the poor sealing and fixing capabilities of the triple offset butterfly valve in the existing technology CN205639645U patent, it is impossible to quickly and effectively fix and lock the triple offset butterfly valve as needed during actual use. This makes it difficult to seal and prevent leakage, thus affecting the user experience of the triple offset butterfly valve. Utility Model Content
