Abstract
Disclosed is a digital display type pressure controller. The controller comprises a housing, a top cover disposed at the upper part of the housing, a pressure sensitive connector, a push rod and a microswitch. A diaphragm, a push block, a sensor, a spring and an adjusting screw are successively disposed between the pressure sensitive connector and the push rod. The sensor is used for reckoning a pressure value. The inner part of the push cover is provided with a data collection device, a button and an output device. The upper part of the top cover is provided with a liquid crystal display screen. The button is connected to the data collection device and used for controlling the operation of the data collection device. The data collection device is connected to the sensor and the microswitch, and used for collecting the pressure value measured by the sensor and allowing the pressure value to be displayed on the liquid crystal display screen through an output device, when the button is pressed down. The controller is simple in structure, and with the above structural design, enables an on-site pressure display function to expand usage performance and improve reliability in actual usage and facilitate fault elimination.
Description
Technical field
The utility model relates to pressure checking device field, relates in particular to a kind of numerical display type pressure controller.
Background technology
In general pressure controller, need before use to preset out a force value, be commonly called as set point.This value is exactly, when inductor receives pressure and produces the displacement making progress, by push rod transmission, just in time to equal to trigger the state of displacement L.Now microswitch action, the state that an exportable circuit is communicated with or disconnects, thus can realize working state control to the connected topworks in outside or warning device.So, only there are two states in general pressure controller: the state of reporting to the police and not reporting to the police.
Under this two states, the force value that during warning, pressure controller is experienced is exported by circuit signal, pulpit or topworks are known, on-the-spot unknowable, and while not reporting to the police, force value scene and pulpit that pressure controller is subject to are all unknowable, but because pressure controller is in use likely due to the fault of machinery or microswitch, there will be the situation of but reporting to the police when force value does not reach set point, be the false alarm that we often say, or the situation of but not reporting to the police when force value meets or exceeds set point.These two kinds of faults, all cannot solve by pressure controller self.Actual with in be by installing a tensimeter additional at same pressure point or transmitter is realized mutual checking.But two nonsynchronous problems of apparatus measures also easily appear in this method, and waste financial resources, install inconvenient.
Summary of the invention
The fault that the utility model exists false alarm or do not report to the police at warning duration for solving the above-mentioned existing pressure controller of mentioning, a kind of numerical display type pressure controller is provided, can directly show force value by display screen, the fault of having got rid of pressure controller false alarm or not reported to the police.
Concrete, the utility model provides a kind of numerical display type pressure controller, it comprises, housing, the top cover that is arranged on housing top, pressure-sensitive junctor, push rod and microswitch, between described pressure-sensitive junctor and described push rod, be disposed with diaphragm, pushing block, sensor, spring and adjust screw, described sensor is connected with two circuit lines, for sense resistance difference, described top cover inside is provided with data collector, button and output unit, and the top of described top cover is provided with LCDs; Described button connects described data collector, for controlling the work of described data collector, described data collector connects described sensor and described microswitch, when described button is pressed, for gather force value that described sensor measurement arrives and by described force value by described output unit in described liquid crystal display screen display.
Preferably, in described top cover, be provided with power supply.
Preferably, described pressure-sensitive junctor by described diaphragm and pushing block by pressure conduction to described sensor, and further reach described push rod and microswitch.
Preferably, when described button is not pressed, when described force value reaches setting value, LCDs not only can show force value, can also play certain onsite alarming effect.
The utility model is simple in structure, by above structural design, can make pressure controller realize the function that on-the-spot pressure shows, has expanded usability, the generation that has increased in actual use reliability and be convenient to fix a breakdown.

Fig. 2 is the structural representation of pressure display module of the present utility model;
Fig. 3 is the structural representation of the utility model duty.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further explained,
As shown in Figures 1 and 2, the utility model provides a kind of pressure controller, it comprises housing 1, is arranged on the top cover 2 on housing 1 top, pressure-sensitive junctor 3, push rod 4 and microswitch 5, between pressure-sensitive junctor 3 and push rod 4, be disposed with diaphragm 6, pushing block 7, sensor 8, spring 9 and adjust screw 10, sensor 8 is for extrapolating force value; Top cover 2 inside are provided with pressure display module, are provided with data collector 20, button 21 and output unit 22 in top cover 2, and the top of top cover 2 is provided with LCDs 23; Button 21 connection data harvesters 20, for controlling the work of data collector 20, data collector 20 connecting sensors 8 and microswitch 5, when button 21 is pressed, the force value measuring for pick-up transducers 8 also shows by output unit 22 force value 8 in LCDs 23.
Preferably, in top cover 2, be provided with power supply 24.
Preferably, pressure-sensitive junctor 3 by diaphragm 6 and pushing block 7 by pressure conduction to sensor 8, and further reach push rod 4 and microswitch 5.
Preferably, when button 21 is not pressed, when force value reaches setting value, LCDs 23 not only can show force value, can also play certain onsite alarming effect.
Below in conjunction with Fig. 1 to Fig. 3, principle of work of the present utility model further describes as follows,
When being subject to extraneous pressure, pressure-sensitive junctor 3 acts on diaphragm 6, diaphragm 6 acts on pushing block 7 by pressure P S (pressure P takes advantage of the area S of diaphragm 6), pushing block 7 again by pressure conduction to sensor 8, sensor 8 by line 1., 2. just have the output △ R of a resistance change, by predicting △ R, just can extrapolate pressure P value like this.
As Fig. 2, in top cover 2, install power supply 24, data collector 20, output unit 22 and button 21 additional, the outside LCDs 23 of installing.When pressing the button 21, data collector 20, by gathering the value of △ R, is presented at force value in LCDs 23 by output unit 22.In actual use, when pressing the button 21, show the force value of current pressure controller, even then while clicking the state of button 21 buttons 21 in not pressing, can cut off demonstration.Cutting off under the state showing, by the circuit diagram shown in accompanying drawing 3, when force value reaches the value of set point PS, the normally open of microswitch 5 is closed, circuit is connected, and the demonstration numerical value of LCDs 23 is not only readable, can also play certain onsite alarming effect.
The utility model is simple in structure, by above structural design, can make pressure controller realize the function that on-the-spot pressure shows, has expanded usability, the generation that has increased in actual use reliability and be convenient to fix a breakdown.
Person of ordinary skill in the field is to be understood that: in the situation that not departing from ultimate principle of the present invention; can carry out various modifications, retouching, combination to the present invention, supplement or the replacement of technical characterictic, these are equal to substitute mode or within obviously mode of texturing all falls into protection scope of the present invention.
