The valve structure form code should generally indicate the valve type, drive mode, connection form, structural characteristics, nominal pressure, sealing surface material, valve body material and other elements; the standardization of the structural form code provides convenience for the design, selection and distribution of the valve. Different valves have different structural form codes.

Butterfly valve structure:

The butterfly valve structure forms are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, of which 0~4 is sealed and 5~9 are unsealed. 0 means sealed type - single eccentricity, 1 means sealed type - center vertical plate, 2 means sealed type - double eccentricity, 3 means sealed type - triple eccentricity, 4 means linkage mechanism, 5 means unsealed type - single eccentricity, 6 means Unsealed type - center vertical plate, 7 means unsealed type - double eccentricity, 8 means unsealed type - triple eccentricity, and 9 means unsealed type - link mechanism.

Gate valve structure:

The gate valve structure code number is 0, 1, 2, 3, 4, 5, 6, 7, 8, 0, indicating the stem lift-elastic gate, 1 means the rod-wedge gate-rigid gate-single gate Board, 2 means open-wedge gate-rigid gate-double gate, 3 means open-parallel gate-rigid gate-single gate, 4 means open-parallel gate-rigid gate Plate - double gate, 5 means dark rod - wedge type gate - rigid shutter - single gate, 6 means dark rod - wedge type gate - rigid shutter - double gate, 7 means dark rod - parallel gate Plate - rigid ram - single ram, 8 for dark rod - parallel ram - rigid ram - single ram, 9 for dark rod - parallel ram - rigid ram - double ram.

Ball valve structure:

The ball valve structure form code is 1, 2, 4, 5, 6, 7, 8, 9, 0, of which 1, 2, 4, 5 belong to the floating ball valve, 6, 7, 8, 9, 0 belong to the fixed ball valve, 1 means Floating ball - straight flow path, 2 means floating ball - Y-shaped three-way flow path, 4 means L-shaped three-way flow path, 5 means T-shaped three-way flow path, 6 means fixed ball - four-way flow path, 7 means fixed Ball-through flow path, 8 means fixed ball-T-shaped three-way flow path, 9 means fixed ball-L-shaped three-way flow path, 0 means fixed ball-hemispherical straight-through.
