Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of heavy weight, large opening and closing strokes and uneven force of the existing cut-off valves of tubular water turbines, and to provide a through-flow valve that is convenient for hydraulic transition and control. Shut-off valves for water turbines can greatly reduce the space required for valve opening and closing, and effectively balance the water pressure on the valves, while significantly reducing the weight of the valves

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, a shut-off valve for a tubular turbine that is convenient for hydraulic transition and control is suitable for shutting off and conducting the water flow of a tubular turbine generator set, specifically including a water guide pipe 1, and the guide water pipe includes a coaxial The connected upstream water pipe 11 and downstream water pipe 12 have a bulb-shaped casing 7 inside the water guiding pipe, so that a tubular water flow cavity 13 is formed between the casing and the water guiding pipe. In addition, a runner 71 is provided at the downstream end of the casing, and a stator and a rotor coaxially connected to the runner are arranged inside the casing. When the guide water pipe guides the water stored in the reservoir to pass through the water flow cavity and impact the runner to rotate, the rotor can be d...

Abstract

The invention discloses a shut-off valve for a tubular water turbine which is convenient for hydraulic transition and control. The elastic body is a connection section used to connect with the tooth plate and transmit torque. One end of the elastic body is connected to the central shaft transmission, and the other end of the elastic body is connected to the connection section. A sensor circuit board is arranged on the outer wall of the elastic body. The sensing circuit board includes a deformation sensor arranged on the outer wall of the elastic body for inductive torque, a wireless signal transmitting module for outputting the torque signal of the deformation sensor, a power receiving coil, and the signal circuit board includes a wireless sensor for receiving the torque signal. The signal receiving module, the power supply coil that induces with the power supply receiving coil to form a supply current on the power receiving coil, and the input and output terminals connected to the controller. The invention can not only ensure the stable transmission of the detection signal, but also help to improve the detection precision.

Description

technical field [0001] The invention relates to the technical field of hydraulic generators, in particular to a shut-off valve for a tubular hydraulic turbine which is convenient for hydraulic transition and control. Background technique [0002] With the enhancement of people's awareness of energy conservation and environmental protection, hydropower as a green energy is developing vigorously. Among them, the tubular turbine occupies an important position in the development of low-head and large-flow hydropower resources in my country, and is widely used in relatively abundant and economical water resources. Water resource development projects in the relatively developed central and eastern regions. When the tubular hydroelectric generator is running, it is often due to changes in working conditions, changes in the operating parameters of the power system, or external disturbances, resulting in changes in water conservancy performance such as water pressure and flow, and the...
