Abstract

The invention discloses an electro-hydraulic integrated control device applied to valve control. The electro-hydraulic integrated control device applied to valve control comprises an actuator connected with the valve (1) and adjusting the valve location. The actuator is connected to a control assembly controlling the operation of the actuator. The control assembly is a hydraulic control mechanism packaged in a cabinet structure. The control assembly is provided with a pipeline connecting with the actuator. The electro-hydraulic integrated control device applied to valve control is reasonable in design. The control assembly is designed into a control cabinet mode, and the control assembly of a filter, a manual pump and the like is arranged reasonably in the control cabinet structurally. The electro-hydraulic integrated control device applied to valve control is simple in operation, can avoid damages to the control assembly from the valve vibration effectively, can increase cleanliness capacity on site and is suitable for the regulation control and the on-off control of devices with any lineal travel movement and angular travel movement.

Description

technical field

[0001] The invention relates to the field of valve control, in particular to an electro-hydraulic integrated control device applied to valve control. Background technique

[0002] For valve control, the actuator can be used to control the valve at any position of fully open or fully closed. During its application, hydraulic oil, gas, electricity or other energy can be used to move it through a motor, cylinder or other device. Converted into actuation action, precisely make the valve go to any position. In the existing field of valve control, existing products integrate control accessories (such as proportional valves, servo valves, etc.) figure 1 Shown:

[0003] (1) When there is vibration in the control pipeline, it will cause the internal wiring of the hydraulic control servo valve installed on the valve actuator to loosen. Of course, the electronic components may even be damaged under high-frequency vibration. Use hydraulic control to prevent panting Ta...

Embodiment

[0030] The present invention proposes an electro-hydraulic integrated control device applied to valve control. Its structure includes an actuator that is connected to the valve 1 and adjusts its valve position. A control component that controls the work of the actuator is connected to the actuator. Generally, In other words, the control components include hydraulically controlled servo valves or proportional valves and various electronic components. In the prior art, the control components are all integrated on the valve actuator, namely figure 1 The structure shown, in figure 1 , the part shown in the dashed box is the control element, and the external oil supply source is usually connected to the control element. In the actual application process, due to the vibration of the control pipeline, high ambient temperature, and large pollution, it often leads to loosening of the control valve (ie: proportional valve or servo valve) and the wiring of various electronic components,...
