Abstract
The utility model discloses an electromagnetic valve which comprises a valve seat, a valve core and a valve cover. The valve core is movably arranged in an inner cavity formed by the valve seat and the valve cover, and at least one of the valve seat and the valve cover is made of a magnetic material and provided with an electromagnetic coil. The valve core is made of the magnetic material. A counter is fixedly connected onto an outer wall of the valve seat and connected with the electromagnetic coil and the valve core. By arranging the counter capable of being read at any time on a casing of the electromagnetic valve, moving times of the electromagnetic valve are displayed visually, working staff can judge when to replace the electromagnetic valve according to the indication, and a circuit is guaranteed to be normal.
Description
Technical field
The utility model relates to the solenoid valve field, is specifically related to a kind of solenoid valve that can the display action number of times.
Background technique
Solenoid valve (Electromagnetic valve) is the industry equipment with Electromagnetic Control, is the automation foundation element of controlling fluid, belongs to final controlling element, is not limited to hydraulic pressure, pneumatic.Be used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system.Solenoid valve can cooperate different circuit to realize the control of expecting, and precision and the flexibility of control can both guarantee.Solenoid valve has a variety of, different solenoid valves plays a role at the diverse location of control system, and the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc., according to different occasions, the solenoid valve that uses is also different, but the principle of solenoid valve is substantially all identical.Solenoid valve generally comprises: valve seat, spool and valve gap, spool are arranged in the internal cavities that forms between valve seat and the valve gap movably, and at least one comprises magnetic material in valve seat or the valve gap, and at least one is provided with electromagnetic coil; Spool is Magnetized Material; After the electromagnetic coil energising, spool is ordered about by magnetic field, will move towards a direction, and pressuring spring deformation, after removing this external force, the spring return, spool is by pop into position.After the permanent action of spring wherein, can lose elastic force, make the solenoid valve can not return.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of solenoid valve that can the display action number of times.
For achieving the above object, the utility model provides following technological scheme: a kind of solenoid valve, valve seat, spool and valve gap, spool is arranged in the internal cavities that forms between valve seat and the valve gap movably, at least one comprises magnetic material in valve seat or the valve gap, and at least one is provided with electromagnetic coil; Spool is Magnetized Material; Fixedly connected counter on the outer wall of described valve gap, this counter connects electromagnetic coil and spool.
Solenoid valve is in running, the every energising of electromagnetic coil once, and the every action of spool once, the counter chance is calculated a number of times, and be presented on the display screen of counter, the total time of movement numerical value of spring in spool has exceeded the product rated wear, namely has spring in the valve portion possibility of power that follows the string, thereby reminds the staff to change solenoid valve.
Described counter inside also has the electronic clock circuit, and the display screen of this circuit linkage counter by the time that this display screen can also be learnt the solenoid valve operation, can further be understood the operation conditions of this battery valve.
On the shell of described counter tutorial light is set, this tutorial light is a red led and a green indicating lamp.Generally, green indicating lamp is long bright, represent normally in servicely, and when situation about setting occurring, red led is long bright, and the prompting staff need change solenoid valve.
The utlity model has following advantage: one, owing at the shell of solenoid valve visible counter at any time is installed, show the time of movement of solenoid valve intuitively, the staff can indicate according to this, judges and when changes solenoid valve, guarantees that circuit is normal; Two, timer also has the electronic clock circuit, shows the working time of solenoid valve, can help the staff further to understand the operation conditions of this battery valve; Three, by the state of this tutorial light, also can help the staff to judge whether solenoid valve moves normally.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model solenoid valve example structure figure.
Among the figure: 1, valve seat; 2, valve gap; 3, spool; 4, counter; 5, electromagnetic coil.
Embodiment
Referring to shown in Figure 1, a kind of solenoid valve, valve seat 1, spool 3 and valve gap 2, spool 3 are arranged in the internal cavities that forms between valve seat 1 and the valve gap 2 movably, and at least one comprises magnetic material in the valve gap 2, also is provided with electromagnetic coil 5 in the valve gap 2 simultaneously; Spool 3 is Magnetized Material; Fixedly connected counter 4 on the outer wall of described valve gap 2, this counter 4 connects electromagnetic coil 5 and spool 3.
Solenoid valve is in running, electromagnetic coil 5 every energisings once, and spool 3 every actions once, the counter chance is calculated a number of times, and be presented on the display screen of counter, the time of movement numerical value total when spool 3 medi-springs has exceeded the product rated wear, namely has spring in the spool 3 possibility of power that follows the string, thereby reminds the staff to change solenoid valve.
Described counter 4 inside also have the electronic clock circuit, and the display screen of this circuit linkage counter 4 by the time that this display screen can also be learnt the solenoid valve operation, can further be understood the operation conditions of this battery valve.
On the shell of described counter 4 tutorial light is set, this tutorial light is a red led, a green indicating lamp.Generally, green indicating lamp is long bright, represent normally in servicely, and when situation about setting occurring, red led is long bright, and the prompting staff need change solenoid valve.
The utility model is not limited to above-mentioned embodiment; the announcement of book and guidance according to the above description; the utility model those skilled in the art also can carry out suitable change and modification to above-mentioned mode of execution, and its change also should fall into the protection domain of claim of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
