Abstract
The utility model belongs to a low-pressure rated-flow automatic monitoring device which comprises a sensor 1, an output port 2, a test cavity 3 and an input port 4. The low-pressure liquid enters into the test cavity 3 from the input port, and is output from the output end 2 after being tested. When the pressure is lower than the preset value, a sensor outputs an open-circuit signal for an alarm circuit to alarm, thereby automatic monitoring the low- pressure rated flow. The utility model has the advantages of simple structure, low cost, high reliability, and convenient rated hydraulic adjustment.
Description
Technical field
The utility model relates to a kind of flow automatic monitoring device, especially with low-pressure lubricating oil or do not have the rated flow of corrosive liquid automatically monitoring is relevant.
Background technology
Existing mechanical equipment adopts low-pressure no corrosive liquid (as liquid coolant) lubricated or other purposes that a rated flow is all arranged, and all can produce harmful effect when cutout or flow are less than normal.Generally to be equipped with the transparent mode flow indicator for artificial cruising, its weak point is to monitor automatically flow in the entire process to this class low-pressure equipment.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, low-pressure rated flow automatic monitoring device that reliability is high.
The purpose of this utility model reaches like this: comprise sensor, delivery outlet, test cavity, input port; Tongue tube is set in the sensor, in the test cavity movement, magnet is set, movement is provided with relief hole, regulator hole; Magnet is in the movement top.
From the above, when input port input liquid, liquid is exported from delivery outlet by relief hole, regulator hole on the movement in the test cavity, and relief hole and regulator hole are subjected to the effect of hydraulic pressure and raise at this moment, the magnet induction tongue tube at movement top, it is normal that tongue tube is connected the expression rated flow.When hydraulic pressure descended, movement also descended, and the tongue tube loss of excitation disconnects, and the control circuit output alarm signal reaches the automatic monitoring low-pressure rated flow purpose of monitoring automatically.
The utlity model has simple in structure, cost is low, reliability is high, regulates advantages such as specified hydraulic pressure is convenient and simple.
Description of drawings
Fig. 1 is the utility model external structure synoptic diagram.
Fig. 2 is the utility model test cavity inner structure synoptic diagram.
Embodiment
Referring to Fig. 1, the utility model comprises sensor 1, delivery outlet 2, test cavity 3, input port 4; Low-pressure liquid enters test cavity 3 from the input port, export from delivery outlet 2 through the test back; When pressure was lower than setting numerical value, sensor output open circuit signal was reported to the police for warning circuit.
Referring to Fig. 2, tongue tube 5 is set in the sensor 1, in the test cavity 3 magnet 7, movement 8 are set, movement is provided with relief hole 9, regulator hole 10; Magnet 7 is in movement 8 tops; Regulator hole 10 belongs to the rotating cylinder of a perforate, can regulate the size that liquid flows through the hole of relief hole 9 and regulator hole 10 by rotation, thereby and decides the numerical value of hydraulic pressure.Movement 8 tops and 3 of cavitys of test are provided with spring 6, can avoid testing the adhesive between cavity 3 and the movement 8, cause control malfunctioning.
From the above, the utlity model has simple in structure, cost is low, reliability is high, regulates specified liquid Press the advantages such as convenient and simple.
