Abstract
The utility model relates to a valve, and particularly relates to a process control diaphragm valve capable of controlling flow, pressure and temperature inside a pipeline and carrying out process record storage. The technical scheme adopted by the utility model is as follows: the process control diaphragm valve is characterized by comprising a control mechanism, a pneumatic actuator and a valve body; the control mechanism comprises a process controller, a locator, a position detector, a sensor, an electromagnetic valve and an air pipe; the position detector is connected to the locator; the sensor is connected to the process controller; the process controller is connected to the locator, and the electromagnetic valve is controlled by the locator. By adopting the scheme, the defects of the prior art are overcome, and a novel process control diaphragm valve with good performance capable of automatically adjusting the opening of the control valve is provided.
Description
Technical field
This is practical newly to relate to a kind of valve, be meant especially its can controlling plumbing fixtures in the process control membrane valve of flow, pressure and temperature and implementation process record retention.
Background technique
Existing valve all is manually operated basically, so on the automated production equipment line, be difficult to coupling, the existence of some intelligent control valves is arranged also in addition; But these intelligent control valve complex structures; Move not quietly, function singleness is so also have significant limitation.
Summary of the invention
This practical new purpose is to overcome the deficiency that existing technology exists, and provides a kind of performance good, can realize the novel process control membrane valve of automatic adjusting control valve door open degree.
In order to realize above purpose; The following technological scheme of this practical new employing: a kind of process control membrane valve is characterized in that: include control mechanism, pneumatic actuator and valve body, wherein control mechanism includes process controller, positioning work piece, position detecting device, sensor, solenoid valve and tracheae; Wherein position detecting device is connected on the positioning work piece; Sensor is connected on the process controller, and process controller is connected on the positioning work piece, and solenoid valve is controlled by positioning work piece.
Adopt such scheme, we make process control membrane valve complete function, particularly can have the function of the open degree of autocontrol valve, and overall structure is simple in addition.
The further setting of the utility model is: described solenoid valve is provided with two groups; They all with the air pressure cavity of pneumatic actuator on the turnover tracheae be connected; The wherein air inlet of one group of electromagnetic valve turnover tracheae, another group electromagnetic valve passes in and out giving vent to anger of tracheae; Said pneumatic actuator includes air pressure cavity, piston, spring and piston rod; Its medi-spring and piston are arranged in the air pressure cavity; Piston rod is fixed on the piston; Said spring is arranged on the upside of piston, the underside gas pressure chamber of piston, and piston is realized moving up and down under the pressure effect of spring and gas pressure chamber.
Through the scheme of further setting, product all can have performance, particularly pneumatic actuator preferably to adopt such scheme on function and effect, and effect is very desirable, and control flow rate is accurate.
Below in conjunction with accompanying drawing to this practical new work further explain.
