Abstract
The invention discloses a muffling, insulating and abrasion resistant device of a solenoid valve. The device comprises an iron core, a yoke iron, a cushion pad, an insulating ring and a housing. The device is characterized in that the housing and the yoke iron form a cavity; the internal end surface is connected with the cushion pad; the cylindrical iron core is arranged in the cavity; the cylindrical surface of the iron core is provided with a circular groove, and the insulating ring is embedded in the circular groove. The device has the advantages that: 1. the iron core is not in direct collision and friction with an outer metal wall any longer in a whole working process, which eliminates noise and abrasion, solves the problem of vortex ablation between the iron core and the housing, and reduces resistance to motion; and 2. the insulating ring can prevent the vortex ablation between the iron core and the inner metal sleeve as well as collision and friction between metals.
Description
Technical field
The present invention relates to a kind of silencing insulation abrasion-proof apparatus, relate in particular to a kind of silencing insulation abrasion-proof apparatus of solenoid valve.
Background technique
When solenoid valve was worked, the moment impact force with the yoke adhesive unshakable in one's determination was very big, and this problem is more outstanding when being used in high-frequency operation for the solenoid valve that big coil electric power is arranged especially.Bump can produce very big noise, also can make simultaneously the end face generation plastic deformation that iron core is impacted and be clashed into burr, motion unshakable in one's determination is obstructed, iron core just is stuck when the most serious, the operating life that shows solenoid valve this moment stops (certainly, if the miscellaneous part of solenoid valve is still intact,, can also work on behind the burr of removal iron core) by repairing.
In addition, electromagnetic valve coil in the current break process of energising and outage can unshakable in one's determination inner, metal-coating is inner and overcoat and iron core between induce eddy current voltage.When this induced voltage is created between overcoat and the iron core, unshakable in one's determination simultaneously may be in contact with one another again with overcoat the time, the phenomenon that electric current is ablated will take place in the surface of iron core and overcoat.Electricity is ablated except that making generation rhegmalypt in surface unshakable in one's determination, the also extra resistance to motion that increases; Rhegmalypt makes the softer iron core wearing and tearing aggravation of quality again.At present, the solenoid valve of ordinary skill all exists these shortcomings.Chinese patent CN200410070561.5, CN200410032832.8, CN200410081689.1 etc. do not relate to the problems referred to above yet.Once occurred on the Domestic market holding on the upper side and had a narrow groove, the solenoid valve of embedded plastic hoop at cylinder unshakable in one's determination.This solenoid valve solved cylinder unshakable in one's determination on the upper side portion do not ablated and iron-free heart wear problems by electricity, but the lower end of cylinder unshakable in one's determination still exists electric current ablation and wear problems unshakable in one's determination.The vibration damping noise reduction problem of also unresolved iron core of this solenoid valve and yoke bump.
Summary of the invention
The object of the present invention is to provide a kind of silencing insulation abrasion-proof apparatus of solenoid valve, this device solves operating noise and end face of iron core are clashed into burr, cylinder unshakable in one's determination is ablated and problem such as mechanical wear, and reduce resistance to motion unshakable in one's determination, improve the operating life of solenoid valve dead electricity action response speed and prolongation general solenoid valve.
The present invention is achieved like this, and it comprises iron core, yoke, damping pad, dead ring, overcoat, it is characterized in that overcoat and yoke form a cavity, the cylinder iron core is arranged in the cavity, cylinder unshakable in one's determination has annular groove, and dead ring is embedded in the annular groove, and the yoke interior edge face connects damping pad.
Annular groove of the present invention is characterized in that annular groove has one or several.
Damping pad of the present invention and dead ring is characterized in that the material of damping pad and dead ring adopts rubber, synthetic rubber or plastics.
Advantage of the present invention is: 1, simple in structure, easy to use, unshakable in one's determination in whole working stroke no longer directly and the metal outer wall friction that collides, both eliminated noise, eliminated wearing and tearing, also eliminated producing the problem that eddy current is ablated between iron core and the overcoat, reduced resistance to motion simultaneously again; 2, dead ring can make no longer eddy generation ablation and intermetallic mutual collision and friction between iron core and the inner metal sleeve.

Fig. 1 is the structural representation of invention.
Unshakable in one's determination 2, yoke 3, damping pad 4, dead ring 5, overcoat in the drawings, 1,
Embodiment
As shown in Figure 1, the present invention is achieved like this, it comprises iron core 1, yoke 2, damping pad 3, dead ring 4, overcoat 5, it is characterized in that yoke 2 end faces connect damping pad 3, yoke 2 connects an end of overcoat 5, and overcoat 5 and yoke 2 form a cavity, have unshakable in one's determination 1 in the cavity, unshakable in one's determination 1 cylinder has annular groove, and dead ring 4 is embedded in the annular groove.
Damping pad adopts polyamine fat synthetic rubber, it is aging also can to adopt the shock-resistant antifatigue of other good springiness to be difficult for, the synthetic rubber of stable performance, rubber or plastics under the solenoid valve Maximum operating temperature, and thickness is for being about 2mm, external diameter is with unshakable in one's determination identical, and internal diameter is identical with guide rod.The corresponding shortening of upper end length 2mm unshakable in one's determination is not changed with the effective travel that guarantees solenoid valve.Dead ring adopts tenacity nylon material, respectively opening a width at 2 positions up and down of iron core is the annular groove of 1mm for the 4mm degree of depth, the thickness of ring is 1.5mm, and the annular groove processus aboralis of packing into goes out surface unshakable in one's determination but also leaves gap about about 0.3mm to guarantee that iron core can unrestricted motion in overcoat with outer inner room.The requirement of dead ring material is the same with damping pad, and it is aging also to require the shock-resistant antifatigue of good springiness to be difficult for, and also should require wear resistance to reach factors such as easily manufactured well, also can adopt and the damping pad identical materials.Only open a wide groove on the cylinder unshakable in one's determination, a wide dead ring only is installed, guarantee that unshakable in one's determination can directly not contacting with metal-coating gets final product in whole working stroke.Be provided with the solenoid valve of a narrow dead ring for some at an end of iron core, can have established a similar groove and dead ring again at the other end.Behind the additional damping pad, erasure effect is obvious especially between iron core and the yoke, impacts the iron core that is caused mutually and is clashed into burr and stuck also existence hardly of problem, has increased the Acceptable life of solenoid valve greatly.
