Abstract
The utility model discloses a detection system for detecting the response time of a pneumatic valve, which comprises a programmable logic controller (PLC), a data monitoring unit and a PB button. The output end of the PLC is connected with a pneumatic valve under test to carry out the on-off operation on the programmable controller. The PB button is connected with the input end of the PLC through the data monitoring unit and is used for sending out control signals. According to the utility model, the response time of a pneumatic valve can be measured through monitoring the switching time interval of the PB button. The detection system is simple in structure. Compared with the complex process and the cost of a professional detection system, the above system is simplified in operation process and lower in cost.
Description
Technical field
The utility model belongs to operated pneumatic valve parameter detecting technical field, the particularly detection system of a kind of response time of pneumatic valve.
Background technology
Pneumatic valve is very wide as production parts range of application commonly used, and most applications are not high for the requirement of its response time; But in some meticulous production environments strict to operating process, the response time of pneumatic valve just seems particularly important.Generally speaking, the response time of pneumatic valve all is to measure by professional measurement means, the flow process complexity, and cost is higher simultaneously.In industries such as smelting production, the replacing of pneumatic valve, frequency of maintenance is higher; Time and expense cost that specialty is measured are higher relatively.Therefore, just need detection means a kind of simple to operate, with low cost.
The utility model content
Technical problem to be solved in the utility model provides the system and device of detection pneumatic valve response time a kind of with low cost, swift to operate.
For solving the problems of the technologies described above, the utility model provides the detection system of a kind of response time of pneumatic valve, comprising: PLC Programmable Logic Controller, data monitoring equipment and PB button; Wherein, described PB button sends to described PLC Programmable Logic Controller by described data monitoring equipment and triggers control signal; The mistiming of twice trigger pip of the described PB button of described data monitoring equipment records; Described PLC Controlled by Programmable Controller is examined the keying of pneumatic valve.
Further, described data monitoring equipment is on-the-spot industrial computer.
Further, also comprise: the PLC switch board; Described PLC Programmable Logic Controller and described data monitoring equipment place in the cabinet.
The detection system of the response time of the pneumatic valve that the utility model provides, testing process is simple, and is quick, the detection requirement the when replacing that can well adapt to the production scene is safeguarded, its detection simultaneously is with low cost, and efficient is higher.
Description of drawings
The structured flowchart of the detection system of the pneumatic valve response time that Fig. 1 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1, the detection system of the response time of a kind of pneumatic valve that the utility model embodiment provides comprises: PLC Programmable Logic Controller, data monitoring equipment and PB button; Wherein, described PB button links to each other with the input end of described PLC Programmable Logic Controller by described data monitoring equipment, the output terminal of described PLC Programmable Logic Controller with examined pneumatic valve and linked to each other.
Be measured as example with the smelting production scene below workflow of the present utility model be described,
Before measuring, connect pneumatic valve and water supply line.The PB button links to each other with pneumatic valve by data monitoring equipment and PLC Programmable Logic Controller successively afterwards.
During measurement, open the PB button and start pneumatic valve, the start-up time of the PB of data monitoring equipment records meanwhile button by the PLC Programmable Logic Controller.When flowing out, pneumatic valve closes the PB button as current, simultaneously the data monitoring following time of equipment records; Calculate the detected value of the time interval as the response time of pneumatic valve with this.
Preferably, data monitoring equipment adopts on-the-spot industrial computer, and its system scan time is 0.05s, and error is very little.
In order to reduce production environment to the influences such as corrosion of measuring equipment, the utility model also comprises a rack, the PLC Programmable Logic Controller of detection system, and data monitoring equipment etc. all is placed in one.
The pneumatic valve response time detection system that the utility model provides, the keying by PB button control pneumatic valve realizes the measurement of the response time of pneumatic valve; In this process, with time interval of the trigger pip of the PB button of real time record detected value as the response time of pneumatic valve.Mechanism is simple, and is swift to operate; Can reach certain accuracy of detection the time with low cost.Also adapt to simultaneously the request for utilization of production scene.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
