Abstract
The utility model relates to a performance parameter detector for three-purpose valves to achieve the automatic acquisition and treatment of data, which can carry out the performance detection on single-body hydraulic prop three-purpose valves for coal mines. The utility model is composed of a connective tee joint between an output port A in a hydraulic circuit of a hydraulic test bench of the three-purpose valve and an accumulator B, and a resistance allergic type pressure sensor. The performance parameter detector for three-purpose valves is characterized in that the sensor is connected with a detection system through the connective tee joint, and the detection system comprises a signal conditioner, an SCM detection system, a PC system, etc. The utility model has the advantages of simple installation and convenient operation, overcomes the problems of redundant human factors in detection and low detection quality, and is suitable to be a novel performance parameter detector for three-purpose valve.
Description
The utility model belongs to tests with hydraulic prop triple-use valve performance to the colliery, realizes the instrument of automatic data collection and processing, is a kind of novel triple-use valve performance parameter detector.
At present mechanical compression table metering system is mainly adopted in the check of triple-use valve, its precision is low, the dwell time is difficult to guarantee, the test figure manual record, and the process of the test human factor is more, is difficult to guarantee to detect quality.
The purpose of this utility model is to design a kind of intelligent data Collection ﹠ Processing System, it and the supporting use of triple-use valve hydraulic test bench, can be to the high pressure sealing quality of triple-use valve, low pressure seal quality, opening pressure and closing presure are judged automatically, automatically detect, automatically record to improve the detection quality of triple-use valve, is a kind of novel triple-use valve performance parameter detector.
The utility model mainly is connected threeway 1 by what the poultry in triple-use valve hydraulic test bench hydraulic circuit can device adds between B and the delivery outlet A, pressure transducer 2 is formed, it is characterized in that pressure transducer 2 being linked to each other with detection system by connecting threeway 1, detection system is by signal conditioner 3, single chip microcomputer test system 4, PC system 5 forms, and pressure transducer can adopt resistance strain type pressure sensor.
The utility model has the advantages that install simple, easy to use, overcome detect in the past in human factor many, detect low-quality problem, realized the robotization that the triple-use valve performance parameter is detected.
Description of drawings: Fig. 1 is a catenation principle block diagram of the present utility model, wherein 1 is to connect threeway, the 2nd, pressure transducer, the 3rd, signal conditioner, the 4th, single chip microcomputer test system, the 5th, the PC system, the 6th, detected triple-use valve, A, B are respectively the delivery outlet and the poultry energy device of triple-use valve testing table hydraulic circuit.Fig. 2 is the signal conditioner theory diagram.Fig. 3 is the single chip microcomputer test system theory diagram.
Before the detection, at first instrument is carried out the setting of various parameters, mainly comprise: high-low pressure sealing detection pressure, opening pressure, closing presure and scope thereof, detection time etc. by input keyboard.And instrument is arranged on automatic measuring ability state.Then detected triple-use valve 6 is installed in the outlet A place of hydraulic system, open the pumping plant of hydraulic system and according to the difference that detects the triple-use valve performance parameter, adjust corresponding delivery outlet pressure, because output pressure is communicated with pressure transducer by threeway, so the pressure that sensor bore suffered pressure that is triple-use valve, instrument will directly detect by pressure transducer, and according to the various parameters that instrument internal is provided with, detects automatically and data processing.The utility model is connected resistance strain type pressure sensor by connecting threeway 1 with triple-use valve testing table hydraulic circuit, be connected with detection system by pressure transducer, and the pressure signal in the hydraulic circuit is converted to electric signal by pressure transducer 2.Since signal of sensor a little less than, wherein also contain various undesired signals, therefore need 3 pairs of these signals of signal conditioner in the system after testing to nurse one's health.Adjusted signal can be detected by single chip microcomputer test system 4 online in real time, and the parameters of triple-use valve performance is discerned automatically, detected and handles.Signal conditioner 3 comprises: operational amplifier U

12, can with the communication of PC computing machine, have in the PC by VB programming application program can with microcontroller communication, acquisition testing data, and database managed.U in the single chip microcomputer test system 4
8It is memory under program.This instrument will be at U when detecting automatically
8Carry out under the control of internal processes.Under the automatic detected state of instrument, at first be to enter real-time detection, and according to set parameter, procedure judges and control instrument enter the detection of certain performance parameter of triple-use valve, and detect the parameters of triple-use valve performance.Testing result can be to detect the back that finishes at each triple-use valve to be shown to prompting by charactron, also can earlier the result be deposited in the E in the instrument
2Among the PROM, export, or pass through the RS-232 interface of instrument itself, be connected data delivery in PC, handle by corresponding program with PC by printer prints.
