Description
Technical field
The present invention relates to a kind of indicator cock, specifically be meant a kind of position indicating switch that is applied on the solenoid valve.
Background technique
Switch commonly used at present has a variety of, as push-button switch, boom guy type switch and self-resetting switch etc., common push-button switch all has the function of automatic indicator cock state, use red symbol as indication as the end that button when switch button is in opening state is upturned, this mode realizes comparatively convenient, also have common mechanical type, the switch of photoelectric, mechanical switch has a movable contact and a rest(ing) contact, when pressing or push switch aside, movable contact just is switched on or switched off with rest(ing) contact, thereby plays the effect that is switched on or switched off circuit; Optoelectronic switch promptly is that then tutorial light is bright when valve position rises, give extraneous indication, indication does not provide feedback signal to computer but this valve position rises, therefore computer can not be learnt the valve position state, also just can not carry out next step relevant information indication easily, therefore in the field of computer extensive use, press for the position indicating switch that can have feedback function.
Summary of the invention
The utility model is the principle according to Hall element conducting under certain magnetic intensity environment, that adopts that high magnetic material neodymium iron boron makes as sense cell a kind ofly is connected a position indicating switch on the pneumatic diaphragm valve, this position indicating switch can provide feedback signal for computer, and computer can be monitored the valve position state.
Hall switch is a kind of magnetoelastic transducer spare, can convert the magnetic input signal to switched electrical signal easily.And high magnetic material neodymium iron boron can make as sense cell and has bigger detection distance and higher valve position indication monitoring accuracy between Hall switch and the magnetic material.
Described position indicating switch is made up of Hall switch, tutorial light, valve position indication cap, fitting seat, high magnetic material five parts.Be threaded in the valve position indication cap, can be threaded on the valve rod of membrane valve, high magnetic material is embedded in the inside of valve position indication cap, Hall switch is fixed on the fitting seat, and maintain a certain distance by the high magnetic material on spring seat and the valve position indication cap, tutorial light places the top of Hall switch, and it is just bright to have magnetic field induction signal rear indicator light between high magnetic material and Hall switch, and the prompting valve position rises.Described position indicating switch is output as open type, when Magnetic Induction element neodymium iron boron position indicating switch closure during near Hall switch, Hall switch sends a short-circuit signal, by relay short-circuit signal being passed to computer receives, realize signal feed back, thereby can monitor the working state of pneumatic diaphragm valve easily by computer.
Position indicating switch of the present utility model is simple in structure, and cost is low, and position indicating switch of the present utility model has characteristics such as contactless, low power consumption, long lifetime.Can be used for pneumatic valve, electromagnetism water valve, occasions such as speed feedback control.By Hall switch computer is carried out feedback information, realized the monitoring of computer the valve position working state.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model relates to a kind of position indicating switch, and described position indicating switch is made up of Hall switch 1, tutorial light 2, valve position indication cap 3, fitting seat 4, high magnetic material 5, and its structural drawing as shown in Figure 1.Position indicating switch is threaded with the valve rod 8 of pneumatic diaphragm valve 10 by valve position indication cap 3, be threaded by the spring seat of fitting seat 4 with pneumatic diaphragm valve 10, the structural representation of pneumatic diaphragm valve 10 as shown in Figure 2, valve rod 8 excircles are threaded 9, the internal surface of valve position indication cap 3 also has the screw thread that matches, valve position indication cap 3 is connected by screw thread 9 with valve rod 8, the cap head of valve position indication cap 3 upwards, and have a hole 11, high magnetic material 5 neodymium iron borons are embedded in the inside of valve position indication cap 3, and high magnetic material 5 carries out induction work by the hole 11 on the valve position indication cap 3 with outside sense cell Hall switch 1.Certain distance is provided with Hall switch 1 on valve position indication cap 3, between Hall switch 1 and valve position indication cap 3 is spring seat 6, spring seat 6 outstanding parts are in the outside of valve gap 7, be connected with fitting seat 4 on the projection, also be threaded between fitting seat 4 and the Hall switch 1, regulate by the height of Hall switch 1 on fitting seat 4, can control the distance between Hall switch 1 and the valve position indication cap 3, valve position indication cap 3 and distance between the Hall switch 1 are controlled at the valve position back valve position that rises and indicate cap 3 not contact with Hall switch 1, and high magnetic material 5 again and have good magnetic action between the Hall switch 1.Fitting seat 4 is used for fixing Hall switch 1, is provided with a tutorial light 2 on the top of Hall switch, and shown in Figure 3 is that position indicating switch of the present utility model is installed in the scheme of installation on the pneumatic diaphragm valve 10.
After pneumatic diaphragm valve 10 is opened, valve rod 8 can rise, valve rod 8 risings drive valve position indication cap 3 and the inner high magnetic material of inlaying 5 rises together, after high magnetic material 5 rises near Hall switch 1 lower end certain position, can give 1 one magnetic signals of Hall switch, Hall switch 1 converts magnetic signal to short-circuit signal, and tutorial light 2 is bright simultaneously, short-circuit signal is passed to computer through relay, finishes the valve position feedback information.
Described high magnetic material is a ndfeb magnet, also can be that aluminium nickel cobalt etc. has ferromagnetic magnet.
