Description

TECHNICAL FIELD

[0001] The utility model relates to the valve field, especially wind pipe regulating valve. BACKGROUND

[0002] The regulating valve, also known as control valve, is mainly used in the field of industrial automation process control. By receiving control signals in the automation system, it automatically adjusts the opening of the valve, thereby achieving precise adjustment of process parameters such as medium flow, pressure, temperature, and liquid level. The regulating valve is generally composed of an actuator and a valve. The actuator can be electric, pneumatic, or hydraulic, and is used to receive control signals and drive the valve to act. The valve is the component that actually adjusts the flow of the medium, and its structure and design may vary depending on different usage requirements.

[0003] In the actual adjustment of the wind pipe regulating valve, the adjustment fastener is used to adjust according to the scale. There may be errors in the cooperation between the adjustment fastener and the scale system, which may lead to inaccurate control of the opening of the valve during the adjustment process, even if the scale is adjusted. This inaccuracy may be due to tolerance problems in the manufacturing process or wear and deformation after long-term use.

[0004] The design of the handle is crucial to the stability of the adjustment process. If the material, shape, or size of the handle is not reasonably designed, it may lead to poor hand feeling during the adjustment process and make it difficult to control stably. For example, a handle that is too thin or too slippery may cause hand sliding during adjustment, making it impossible to accurately adjust the opening of the valve.

[0005] In practical applications, the wind pipe regulating valve may be disturbed by external factors such as vibration and temperature changes. These factors may cause the adjustment fastener to loosen or deform, affecting the stability of the adjustment process. In addition, if the valve is installed in an inappropriate position, such as being subjected to excessive pressure or tension, it may also lead to unstable adjustment. INVENTION CONTENTS
