Description
Technical field
The utility model belongs to liquid-level switch technical field, specifically a kind of easy-operation type security alarm liquid-level switch.
Background technique
In the prior art, float type level switch is more common, and industrial common structure is the hollow cylinder in sealing
Built-in magnetic reed switch, then in hollow cylinder housing floating ball, floating ball is equipped with magnet, with floating ball up and down, magnet influences magnetic red and opens
The movement of pass.After long-term use, impurity in liquid etc. can be adhered to outside hollow cylinder and floating ball, caused hollow cylinder and floated
Relative motion clamping stagnation between ball, is unable to learn in time liquid level, can not also know the case where device failure in some hollow cylinders
Liquid level causes liquid level excessively high.Currently, solving the problems, such as this, usually the output signal of liquid-level switch is monitored, to exception
State carries out automatic or manual identification, when necessary, site inspection, maintenance replacement.Which is more time-consuming, has identification careless omission can
It can property.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of easy-operation type security alarm liquid
Bit switch including hollow pipeline and covers the first floating ball outside hollow pipeline；Multiple magnetic are housed along the vertical direction in hollow pipeline
Spring switch, first floating ball is equipped with magnet corresponding with each magnetic reed switch, it is characterized in that further including alarm device；Alarm dress
Set the trigger mechanism including microswitch, the second floating ball and microswitch；The contact extraction wire of the microswitch is (for sending out
Warning information out)；The microswitch is connected to the top of hollow pipeline outer wall；
The trigger mechanism of microswitch includes conduit, first piston, second piston and the second floating ball；The conduit is
" L " type；Conduit is connected to outside hollow pipeline by bracket；Height where the height of conduit horizontal segment and the button of microswitch is right
It answers, and the open end of conduit horizontal segment is towards the button of microswitch, and first piston is connected in open end, first piston connects
Contact bar；Pressure spring is connected between first piston and hollow pipeline outer wall；Conduit vertical section it is opening down, in conduit vertical section
Open end in connect second piston, second floating ball by connecting rod be connected to second piston lower section；The head end of the connecting rod
Outer wall is equipped with external screw thread, and the second floating ball is equipped with band internal thread through-hole, and the second floating ball rotates the head end for being connected to extension rod；
The axis of through-hole passes through the centre of sphere of the second floating ball；
Filled with air in conduit；Tracheae is connected on conduit, the end of tracheae is connected with air charging system.
The principles of the present invention are, when liquid level rising reaches warning liquid level, and the sliding of the first floating ball is unsmooth, by the
Two floating balls float the button of pressing microswitch, and then alerted by the external circuit for microswitch contact of ining succession outside (such as
The switching value that microswitch is inputted as PLC).Since air is influenced by temperature etc., the effective travel of feeler lever will affect.And
The total volume that air is finely tuned by the air charging system on branch pipe can solve this problem.
In addition, the warning of Lai Shiyong different height liquid level requires by height adjustment of second floating ball on connecting rod.
In Project Realization, two open ends of conduit can install the blind plate with through-hole, for preventing piston from surprisingly sliding
Conduit (under normality, can ensure that two pistons do not skid off conduit by the pressure difference at piston both ends) out.Through-hole on blind plate is for connecting
The rod-like structure connect on piston passes through.
Further, the pressing plate of outer convex is connected on the feeler lever.The structure ensures reliably to press microswitch
Button.
Further, the air charging system is inflating balloon.
Inflating balloon can be connected by tracheae in the outside of fluid to be measured container, such as from the top of open container
Propelling container opens dedicated through-hole propelling container on hermetically sealed container.
Inflating balloon can be medical gas-filled sacculus, such as the medical gas-filled sacculus on sphygmomanometer, this sacculus band
There is a pair of of check valve, but also has relief valve and pointer pressure gauge.
Due to belonging to fine tuning to the air pressure in hollow conduit, hand-pinch type sacculus can be met the requirements.
The utility model is suitable for the warning of a variety of liquid levels, and conveniently adjusted to cope with different variations.
