Description
Technical field
The utility model relates to solenoid valve, especially relates to a kind of remote signal feedback solenoid valve.
Background technique
At present, most of solenoid valves all do not have the remote signal feedback function, to such an extent as to user's industrial control pipeline or equipment breaks down or during anomaly in use, must go to the erecting bed of solenoid valve, great inconvenience has been brought away from control room or the situation that is installed in special occasions such as high-altitude in this infield of giving solenoid valve; In addition, if maintenance sites has a lot of solenoid valves, the maintenance man still haves no way of handling, in addition the user all to be difficult to determine the end be that solenoid valve is out of joint or other pipeline equipment is out of joint.So, address this problem the remote signal feedback function that must make solenoid valve possess valve position open and close state.
Need based on this, the domestic coil top that also has indivedual producers position limit switch to be installed in solenoid valve, take in the perforate of plunger tube top and load onto the O RunddichtringO, and outside the plunger tube top, extend the mode that part is utilized the mechanical contact shell fragment that its impact stroke opens when the upper and lower motion of the suction magnetic force of electromagnetic coil, thereby reach the signal feed back effect by moving magnetic core lengthening.The complex structure of this signal feedback device, and if the solenoid valve of first guide structure, can give the long-range error signal of sending if its main valve plug breaks down equally when not opening, the sort signal feedback means also exists moving magnetic core vibrated by electromagnetic coil power supply fluctuation meeting and causes that signal feed back unstable properties, while O RunddichtringO can be that a kind of passive signal is not easy to and shortcomings such as industrial control is connected because of wear and aging causes leakage, position limit switch easily.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of stable and reliable for performance, compatible good, install and overhaul remote signal feedback solenoid valve easily.
The purpose of this utility model can be achieved through the following technical solutions: remote signal feedback solenoid valve, comprise electromagnetic coil, valve body, spool, it is characterized in that, described electromagnetic coil comprises enameled wire loop, coil case, described valve body comprises plunger tube, valve gap, described spool comprises moving magnetic core, spring, piston, guide rod, inductive magnetic steel, and described electromagnetic coil is connected with the plunger tube at valve body top, and described spool is located in the valve body; Also comprise signal feedback device, this signal feedback device comprises mounting base, signal emitter, and described signal feedback device is connected with the valve body bottom.
Described signal feedback device is a cylinder type.
Described signal emitter moves by the upper and lower position of collecting spool and changes the real open and close state of solenoid valve that transmits.
Described signal emitter apolegamy various feedback signal type comprises switching value mono signal, switching value dual signal, analog signals.
Described signal emitter can directly be connected with industrial control module.
Described signal emitter is installed in the outside of solenoid valve.
Described signal emitter is complete enclosed package.
Compared with prior art, solenoid valve of the present utility model has the following advantages:
1. technology is more advanced: the signal emitter that is adopted is that what to utilize that Spaciousness should survey and obtain is accurate actual signal, and can match multiple signal output and can directly be connected with industrial control module;
2. stable and reliable for performance: what signal feedback device adopted is light current control, with the forceful electric power source mutual noninterference of electromagnetic valve coil, and safety, stable, reliable;
3. good seal performance: signal feedback device not with valve body in fluid any contact taken place, its device can not influence the original sealing of solenoid valve, can not cause external leakage;
4. it is convenient that maintenance is installed: the signal emitter small volume structure is simple, and sensitivity adjusting is conveniently overhauled and changed and can operate at any time, but also can not influence the proper functioning of solenoid valve;
5. application area is more extensive: signal emitter independently is present in outside the valve body, can not influence solenoid valve application area and advantage originally, problems such as material because of O type circle, leakage have been solved in the prior art, enlarged application area, can be transplanted on the solenoid valve of various variety classeses, different principle structure.
