Abstract
The utility model relates to a pressure alarm switch which can be powered in pneumatic, mechanic and electric way. The utility model is formed by installing a discretion pressure alarming switch on a base; the inside of the pressure alarming switch consists of a right upper pressing board and a right lower pressing board; a film piece is arranged under the lower pressing board while a spring is arranged on the upper pressing board. The circuit is closed by the inner conducting strips under the mutual functions of the gas pressure and the spring force, thereby making a buzzer which is connected on the circuit give an alarm, solving the problem that an oxygenerator can not give an alarm on the condition of the during the exceedingly high pressure or the exceedingly low pressure during the operating process. The utility model has simple structure, convenient operation, foreign exchange saving, sensitive alarming and wide applying range.
Description
Technical field
The warning device that the utility model belongs to is pneumatic, mechanical, fax is moving
Background technology
In the operation process of oxygenerator, the gas pressure change in the adsorption tanks should be in the scope, can not be too high or too low, and both of these case is in case long-time existence all needs warning.Generally use pressure sensor now, pressure sensor needs external import, cost height.The pressure alarm switch of using on machine tool at present is to report to the police by the pressure pull switch, not exclusively is fit to the warning of oxygenerator operation process.
Summary of the invention
The utility model is to adopt pressure alarm, by the inner conductive sheet under the interaction of gas pressure and spring force, closed circuit, thus make the buzzer warning that is connected on the circuit, both solved hypertonia, solve again under the hypotony situation and can both report to the police.
The technical solution of the utility model is that two alarm switch assemblies are housed with being threaded on base 2, the left side is the alarm for high voltage switch, the right side is a low pressure warning switch, the left side of base has the oxygenerator gas passage to take over 1, and the alarm for high voltage switch has following 4, loam cake 3, interconnect by screw thread, also there is external screw thread the lower end of following seat, is connected with base, on the following seat diaphragm 6 is arranged, there are trim ring 5 and lower platen 7 in the diaphragm top, conducting strip 8 is equipped with in the lower platen top, is installed with median septum 10 above, and conduction card 9 is housed on the median septum 10, pass on the conduction card and be stamped two lead-in wires 16, lead-in wire 16 connects buzzer, and adjusting rod 12 is equipped with in the upper end of loam cake, passes above and is stamped locking nut 13, be with adjusting nut 14 below the adjusting screw(rod), spring 15 is arranged under the nut, top board 11 is arranged below the spring, the bottom of top board contacts with lower platen 7.The difference of low pressure warning switch and alarm for high voltage switch, just conducting strip 8 is contained on the top board 11, and median septum 10 turns over turnback by dress.
The utility model is simple in structure, and is easy and simple to handle, and cost is low, but import substitution spare is saved foreign exchange, but for high-low pressure alarm range regulated at will, it is sensitive, applied widely to report to the police.

The concrete real mode of implementing
Below in conjunction with description of drawings operation principle of the present utility model and operating procedure
Operation principle: regulate the spring in the pressure alarm switch, make the interior gas of the adsorption tanks of being taked press when being higher or lower than the specified pressure value, the conducting strip of pressure alarm switch inside spring deformation elastic force and gas pressure the two make useful closing of circuit down, buzzer sends alarm sound.
Operating procedure:
1, regulates the alarm for high voltage switch: conducting strip is fixed on the lower platen, by assembling
The order assembling feeds 0.18Mpa gas.Regulating adjusting rod is in switch
The position of just not reporting to the police.
2, regulate low pressure warning switch: conducting strip is fixed on the top board, by assembling
Along assembling, feed 0.14Mpa gas.Regulating adjusting rod is in just switch
Good position of not reporting to the police.
3, simultaneously the high and low pressure alarm switch is connected with circuit, the gas circuit of machine.When
When the pressure of gas was higher than 0.18Mpa in the gas circuit, the pressure of gas was greater than bullet
The elastic force of spring upwards promotes spring by diaphragm, and conducting strip and circuit are connect
Touch, at this moment buzzer warning (as Figure 17); In like manner, gas in gas circuit
Pressure when being lower than 0.14Mpa, the pressure of gas is less than the elastic force of spring,
Spring presses pressing plate downwards, makes conducting strip and circuit contacts, at this moment buzzer
Report to the police (as Figure 18).
Claims (1)
1, a kind of pressure alarm switch closes, it is characterized in that on base 2 being equipped with two alarm switch assemblies with being threaded, the left side is the alarm for high voltage switch, the right side is a low pressure warning switch, the left side of base has the oxygenerator gas passage to take over 1, and the alarm for high voltage switch has following 4, loam cake 3, by screw thread mutually repeatedly, the lower end of following seat also has external screw thread to be connected with base, on the following seat diaphragm 6 is arranged, and there are trim ring 5 and lower platen 7 in the diaphragm top, conducting strip 8 is equipped with in the lower platen top, be installed with median septum 10 above, conduction card 9 is housed on the median septum, pass on the conduction card and be stamped two lead-in wires 16, lead-in wire 16 connects buzzer, adjusting rod 12 is equipped with in the upper end of loam cake, passes above and is stamped locking nut 13, is with adjusting nut 14 below the adjusting screw(rod), spring 15 is arranged under the nut, top board 11 is arranged below the spring, and the bottom of top board contacts with lower platen 7, the difference of low pressure warning switch and alarm for high voltage switch, just conducting strip 8 is contained on the top board 11, and central dividing plate 10 turns over turnback and installs.
