The barometer with the emergency stop device comprises an air inlet and a shell, and is characterized in that the air inlet is formed at the upper end of the shell; an induction membrane is arranged in the shell; a pressing sheet is arranged at the lower end of the induction membrane; the lower end of the pressing sheet is connected with a guide rod; and the bottom in the shell is provided with a spring which is connected with the lower end of the guide rod. Compared with the prior art, the barometer with the emergency stop device has the advantages that 1, the production cost is low, and readings are accurate; 2, the barometer is convenient to maintain, and can be maintained by ordinary technicians because complicated connecting circuits are avoided; 3, the emergency stop device is arranged, so that the barometer can emergently stop before the danger occurs, and is also safe under the condition of unmanned operation; 4, the barometer has a small size, is convenient to install, and does not occupy space; and 5, the barometer has a wide application range, can be used for large pneumatic cutting devices, and can also be used for equipment such as pneumatic tools for decoration.
Description
Technical field
The utility model relates to a kind of technical field of inductor, especially a kind of air pressure inductor that emergency stop device is arranged.
Background technology
The air pressure inductor is a kind of inductor of induction air pressure intensity; Our utilizable power source is more and more now, and air pressure is exactly a kind of power resources wherein, its purposes is very extensive, can be used for the work purposes of the aspects such as cleaning, maintenance, manufacturing, but because technology is immature, many times have the existence of labile factor, cause its pressure excessive, cause burst accident, in this case, be to be sought after a kind of instrument that can in time detect accurately air pressure intensity size, this instrument is exactly the air pressure inductor.
At present, in the prior art of China, the research and development of responding to for air pressure are relatively backward, and most of with the electronic technology realization, and the defectives such as its cost is high, maintenance difficult all put to no little inconvenience to the research and development of its relevant art.
Open file (CN201867277U) the utility model provides a kind of baroceptor, comprise a pressure sensing chip, described pressure sensing chip signal output part connects an operation amplifier chip signal input end one operation amplifier chip, and described air pressure signal output terminal connects described amplification chip signal output part.Wherein, described pressure sensing chip voltage signal input pin connects a wave filter.The utility model is simple in structure, and air pressure detects respond well, can be useful in multiple specific environment and carry out the air pressure detection.
Disclose a kind of baroceptor in the open file (CN201867277U), the shortcoming of this baroceptor also is very obvious: 1, high cost; 2, maintenance difficult is not that the maintenance personal of specialty can not keep in repair at all; 3, can not automatically stop air pressure and raise, this is breakneck, if when the prosthetic operation, does not automatically stop air pressure and raises, and the risk that has blast exists.
Summary of the invention
The utility model provides a kind of air pressure inductor that emergency stop device is arranged for solving the problem of above-mentioned existence;
The technical solution of the utility model is achieved in that
A kind of air pressure inductor that emergency stop device is arranged includes shell and air intake opening, it is characterized in that: described shell upper end is provided with air intake opening, be provided with sense film in the shell, the sense film lower end is provided with compressing tablet, and the compressing tablet lower end is connected with guide rod, the shell inner bottom part is provided with spring, connects the lower end of guide rod;
One side of described spring is connected with potentiometer;
Described outer casing bottom is provided with adjusting screw;
Be provided with shell fragment between described sense film and the compressing tablet;
Described potentiometer is connected with electronic controller.
Beneficial effect
The utility model with respect to prior art its relatively outstanding advantage have: 1. cheap, production cost is low and controllability is high; 2. easy to maintenance, there is not complicated connecting circuit, general technician can both keep in repair; 3. emergency stop device is arranged, can before danger occurs, suddenly stop, in the situation that the prosthetic operation is also very safe; 4. volume is little, and convenient the installation do not take up space; 5. applied widely, can be used for large-scale air pressure cutter sweep, also can be used for the equipment such as finishing pneumatic tool.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The 1-shell; The 2-air intake opening; The 3-sense film; The 4-compressing tablet; The 5-guide rod; The 6-spring; The 7-potentiometer; The 8-adjusting screw; The 9-shell fragment; The 10-electronic controller.
Embodiment
A kind of air pressure inductor that emergency stop device is arranged includes air intake opening 2 and shell 1, it is characterized in that: described shell 1 upper end is provided with air intake opening 2, shell 1 bottom is provided with adjusting screw 8, be provided with sense film 3 in the shell 1, sense film 3 lower ends are provided with compressing tablet 4, are provided with shell fragment 9 between sense film 3 and the compressing tablet 4, compressing tablet 4 lower ends are connected with guide rod 5, the shell inner bottom part is provided with spring 6, connects the lower end of guide rod 5, and spring 6 one sides are connected with potentiometer 7, potentiometer 7 is connected with electronic controller 10.
Potentiometer effect of the present utility model is to induce air pressure intensity by resistance variations; The regulating spring spring length of passing through of the effect of adjusting screw is come the regulating spring elastic force, changes anti-pressure ability, thereby changes air pressure warning line height.
Principle of work of the present utility model is such, regulates the height of the anxious air pressure warning line that stops by adjusting screw, and air intake opening connects the air pressure output channel, gas enters from air intake opening, pushes down sense film, and sense film down transmits pressure, spring-compressed, potentiometer resistance changes; If air pressure intensity surpasses warning line, spring just can not connect potentiometer, potentiometer outage, the source of just suddenly stopping the supple of gas or steam.
