Abstract
The invention relates to a valve arrangement and a method for actuating a valve arrangement having a 2/2-way proportional valve and a switching valve. The valve arrangement receives a single control signal and generates individual actuation signals from this control signal for the individual valves of the valve arrangement.
Claims10
Valve arrangement (1), having:
- a 2/2-way proportional valve (11), which is connected at one port to an application port (23);
- a switching valve (12), which is connected at one port to the application port (23);
- a control device (10), having
- a setpoint interface (10a), which is designed to receive a control signal for a setpoint,
- a first actuation interface (10b), which is designed to output a first actuation signal for actuating the 2/2-way proportional valve (11), and
- a second actuation interface (10c), which is designed to output a second actuation signal for actuating the switching valve (12),
- wherein the control device (10) is designed to generate the first actuation signal for actuating the 2/2-way proportional valve (11) and the second actuation signal for actuating the switching valve (12) respectively using the same received control signal for the setpoint.
Valve arrangement (1) according to one of the preceding claims, wherein the control device (10) is designed to actuate the switching valve (12) if the control signal for the setpoint exceeds a first threshold, and to actuate the 2/2-way proportional valve (11) if the control signal for the setpoint exceeds a second threshold, wherein the second threshold is greater than the first threshold.
Valve arrangement (1) according to one of the preceding claims, wherein the 2/2-way proportional valve (11) is arranged between a fluid inlet (21) and the application port (23), and wherein the switching valve (11) is arranged between the application port (23) and a fluid outlet (22).
Valve arrangement (1) according to one of the preceding claims, wherein the switching valve (11) is designed as a Normally Open NO valve.
Valve arrangement (1) according to one of the preceding claims, having a configuration device, which is designed to set the first threshold and/or the second threshold.
Valve arrangement according to one of the preceding claims, having at least one sensor, in particular at least one pressure sensor and/or at least one temperature sensor, which is designed to detect an operating parameter in the valve arrangement (1) by means of sensors,
- wherein the control device (10) is designed to adjust the actuation of the 2/2-way proportional valve (11) and/or switching valve (12) using the operating parameters detected by means of sensors and/or to detect a malfunction in the valve arrangement.
Valve arrangement (1) according to one of the preceding claims, wherein the application port (23) is designed to be coupled to an actuator (3), and to actuate the actuator (3) using a fluid provided at the application port (23).
Fluid-controlled actuator device, having:
- at least one actuator (3), which is designed to perform an actuation using a fluid flow and/or a fluid pressure of a valve arrangement (1) according to one of the preceding claims;
- wherein the application port (23) of the valve arrangement (1) is coupled to a fluid port of the at least one actuator (3).
