Abstract
The utility model discloses a silencing 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 between the valve seat and the valve cover, at least one of the valve seat and the valve cover is made of a magnetic material, and an electromagnetic coil is arranged in at least one of the valve seat and the valve cover. The valve core is made of the magnetization material. A buffer plug is arranged at a valve port position of the top of the valve core. Due to the buffer plug arranged on the valve core of the electromagnetic valve, action of the valve core is impacted on the buffer plug each time, impacting strength of the valve core can be reduced, and action noise of the electromagnetic valve can be eliminated.
Description
Technical field
The utility model relates to the solenoid valve field, is specifically related to a kind of noise reduction solenoid valve.
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, 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, when solenoid valve moves at every turn, spool has very strong motion, form bump, so in the solenoid valve action, people can hear the sound of very loud ticktock, long-term action like this, easily spool is caused damage, influence the working life of solenoid valve.
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 effectively protect spool.
For achieving the above object, the utility model provides following technological scheme: a kind of noise reduction solenoid valve, comprise: 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 is provided with electromagnetic coil at least one; Spool is Magnetized Material; Valve port place at described spool top arranges cushion plugs.
Preferably, described cushion plugs is rubber or rubber or sponge.
Preferably, described cushion plugs is annular, and is adhesive in valve port.
Preferably, the thickness of described cushion plugs is 0.2mm.
By adopting technique scheme, owing at the spool of solenoid valve cushion plugs is set, the each action of spool impinges upon on the cushion plugs, not only can reduce the impact strength of spool, in the time of can also making the solenoid valve action, and the noise when eliminating action.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's structural drawing.
Among the figure: 1, valve gap; 2, spool; 3, valve seat; 4, cushion plugs; 5, valve port.
Embodiment
Referring to shown in Figure 1, be the embodiment of noise reduction solenoid valve shown in the figure, comprising: valve seat 3, spool 2 and valve gap 1, spool 3 are arranged in the internal cavities that forms between valve seat 3 and the valve gap 1 movably, comprise magnetic material in the valve gap 1, be provided with electromagnetic coil in the valve gap 1; Spool 2 is Magnetized Material; Valve port 5 places at described spool 2 tops arrange cushion plugs 4.
Described buffer part 4 is rubber or rubber or sponge.
Described buffer part 4 is annular, and is adhesive in valve port 5.
The thickness of described buffer part 4 is 0.2mm.
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.
