Description

Technical Field

[0001] The utility model relates to the field of baffle valve blades, in particular to a baffle valve blade for a gas turbine. Background Art

[0002] The existing flapper valve blade structures for gas turbines are similar and can meet basic requirements, but the conventional flapper valve blades are not properly matched, which leads to poor overall sealing and potential safety hazards. The utility model adopts a new blade matching structure, which can make the flapper valve blade fit in place during normal operation to ensure sealing. Summary of the invention

[0003] The utility model aims to provide a baffle valve blade for a gas turbine.

[0004] The above-mentioned purpose is achieved through the following technical scheme: The utility model is a new type of gas turbine auxiliary system soft connection structure composed of: blades, blade stops, driven shafts, cross pan head bolts, and connecting bolt groups, which have the advantages of good sealing and opacity.

[0005] A baffle valve blade for a gas turbine: the cross pan head bolt (4) fixes the blade (1) and the driven shaft (3); a connecting bolt group (5) fixes the blade (1) and the blade stopper (2); and two blade stoppers (2) are in contact with adjacent blades (1) respectively.

[0006] The fixed blade (1) and the blade stopper (2) need to be fixed with a connecting bolt assembly (5) to prevent loose sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is an axonometric drawing of the utility model.

[0008] Figure 2 It is a connection diagram of each component of the utility model. DETAILED DESCRIPTION

[0009] Embodiment 1: The utility model is a novel gas turbine auxiliary system soft connection structure, which comprises: blades 1, blade stops 2, driven shafts 3, cross pan head bolts 4, and connection bolt groups 5, and has the advantages of good sealing and opacity.

[0010] Embodiment 2: The fixed blade (1) and the blade stopper (2) need to be fixed with a connecting bolt assembly (5), and the two layers of blades are completely fitted together to ensure a sealing effect; the two blade stoppers (2) are in contact with adjacent blades (1) respectively.

Claims

1. A flapper valve blade for a gas turbine, characterized in that: It comprises a blade (1), two blade stoppers (2) and two connection bolt groups (5), wherein the two blade stoppers (2) are respectively connected to the upper and lower sides of the blade (1) through corresponding connection bolt groups (5), and the two blade stoppers (2) are respectively in contact with adjacent blades (1).

2. The gas turbine damper valve blade according to claim 1, characterized in that: A driven shaft (3) passes through the blade (1), and a plurality of cross pan head bolts (4) are installed between the blade (1) and the driven shaft (3).
