Automatic precision pressure regulating valve

Abstract

The invention discloses an automatic precision pressure regulating valve. The automatic precision pressure regulating valve is aimed at solving the problems that an existing pressure regulating valverelies on manual adjustment, and has low regulating speed, the numerical value of the existing pressure regulating valve is not easy to control, and is easily affected by external factors such as accidentally touching by workers, and the valve cannot be in joint debugging with a system. The following technical scheme is now put forward. The automatic precision pressure regulating valve comprises abase, wherein a stepping motor is fixed to the inner wall of one side of the base through a bolt; a synchronous wheel a is fixed to the top end of an output shaft of the stepping motor through a screw; the outer wall of the synchronous wheel a is in sleeve connection with a synchronous belt; the inner wall of one side of the synchronous belt is in sleeve connection with a synchronous wheel b; theinner wall of the synchronous wheel b is connected to an adjusting screw rod through a thread; a pressure regulating valve is fixed to the inner wall of the bottom of the base through a bolt; and thetop end of the pressure regulating valve is in sleeve connection with a bearing. Instructions are sent to the stepping motor in real time through a control board according to the feedback numerical value of a pressure acquisition board; the stepping motor drives the adjusting screw rod; a microswitch is touched through the adjusting screw rod so as to control the stepping motor without manual labor; and the joint debugging of the automatic precision pressure regulating valve and the system is realized.

Description

technical field [0001] The invention relates to the technical field of limit devices, in particular to an automatic precision pressure regulating valve. Background technique [0002] Pressure regulating valve, also known as self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, and flow balancing valve, is an intuitive and simple flow regulating control device. Pressure regulating valve, by driving the valve to change the cross-sectional area between the valve core and the valve seat, controls the flow, temperature, pressure and other process parameters of the pipeline medium to realize the regulating function. [0003] The adjustment of manual pressure regulating valves on the market requires manual adjustment. The adjustment speed is slow and the value is not easy to control. At the same time, the value is easily affected by external factors such as accidental touches by workers, and cannot be coordinated with the system. However, exis...
