Embodiment

[0026] Example: such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 A multi-position stroke gate valve is shown.

[0027] A multi-position stroke gate valve includes a gate opening device 1 , a transmission device 2 , a stroke device 3 and a gate valve device 4 . The gate opening device 1 includes a side plate 104 , a fixed upper plate 105 , a motor 108 , and a lifting slider 116 . The transmission device 2 includes a transmission chamber plate 201 , a driven worm 203 , and a driven half rack 216 . The stroke device 3 includes a fixed connection 301 , a driven half gear 305 , a cam follower plate 306 , and a pressing spring 308 . The gate valve device 4 includes a connecting plate 401 and a side fixing plate 404 .

[0028] The side plate 104 is fixedly installed on the lower surface of the fixed bottom plate 102, the fixed upper plate 105 is fixedly installed on the lower surface of the sealing plate 103, the motor 108 is fixedly ins...

Abstract

The invention discloses a multi-gear stroke gate valve. The multi-gear stroke gate valve comprises a gate opening device, a transmission device, a stroke device and a gate valve device which are installed on a rack. The multi-gear stroke gate valve is fixedly installed on a bank of a river levee, and when the river levee needs to be opened, a mechanical set in the transmission device operates to drive a mechanical set in the stroke device to operate according to the height of a valve gate needing to be opened, when the stroke device operates, a gate on the gate valve device is driven to move upwards so as to increase water flow, when the valve gate needs to be opened completely, the mechanical set in the transmission device operates to drive the stroke device and the gate valve device to move upwards, and when the gate valve device moves upwards to a certain degree, the valve gate rotates by 90 degrees and moves backwards to a certain degree for self-locking, so that the maximum flowing of the water flow is achieved.

Description

technical field [0001] The invention relates to the field of opening and closing of gate valves, in particular to a gate valve with multiple gear strokes. Background technique [0002] Gate valves are installed on many river embankment pipelines. This kind of device requires manual opening and closing of gate valves to achieve the purpose of controlling water flow. There are great safety hazards when operating in an environment with large water flow. In order to solve this Problem, application number CN201920380115.6 discloses a gate valve welded in a medium, but the device has a simple structure and cannot automatically control water flow. Contents of the invention [0003] Aiming at the above technical problems, a multi-position stroke gate valve comprises a gate opening device, a transmission device, a stroke device and a gate valve device. [0004] The gate opening device includes a side plate, a fixed upper plate, a motor, and a lifting slider. The transmission devi...
