Utility model content

The purpose of this utility model is to provide a kind of small silent three-way magnetic valves, to solve to exist in the prior art Foregoing problems.

To achieve the goals above, the technical solution adopted in the utility model is as follows:

A kind of small silent three-way magnetic valve mainly includes valve body, fixed spool, movable valve plug, end cap, coil holder and line Circle；Wherein the fixed spool is arranged on the valve body, and the coil holder is embedded in valve inner, and the coil holder periphery is around wired Circle, be cased with inside the coil holder can on-off air-flow the movable valve plug, the end cap is fixed on the lower end of the valve body.

Preferably, the coil holder center has through-hole, for the position of installation activity spool and spring, the fixed spool Lower end and at the outer of the movable valve plug upper end be arranged it is fluted, for disposing spring.

Preferably, movable valve plug upper and lower sides are respectively equipped with a gasket, and are bonded in movable valve plug with glue.

Preferably, the fixed form of the end cap is fixed with bolt, and O type circle is used between the end cap and the coil holder Sealing.

Preferably, the movable valve plug and the gasket of fixed spool cooperation are higher by 0.1- than movable valve plug surface 1.0mm。

Preferably, the coil holder is socketed on the fixed spool by O-ring and the coil holder, seals the fixed valve Core.

Preferably, the movable valve plug is cylindricality, but there are the channels that gap is passed through as air-flow between the coil holder.

Preferably, movable valve plug is the cylindrical body or polygon cylinder that two sides are scabbled.

Preferably, the solenoid valve includes setting that there are two interface, hollow fixed spools on the end cap there are three interface It is equipped with an interface.

Preferably, the solenoid valve includes two metering orifices, is located at the upper and lower side of the movable valve plug.

The beneficial effects of the utility model are:

The small silent three-way magnetic valve structure that the utility model obtains is simple, and there are three interface, a total energy connection is another One in outer two, one is always on, and one is always off, and can be mounted to closed type but also be mounted to the electricity of open type Magnet valve can save space in use, and due to being to be fixed by bolts between end cap and valve body, occur in use It is airtight, when neglected loading etc. is bad, the screw on end cap can be easily unclamped, is repaired, without dismantling valve body；Test is facilitated to install And maintenance.And gold will not be issued using gasket or O-ring connection sealing when in use between the component that may be hit Belong to the sound hit, achievees the effect that mute.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality It is further elaborated with novel.It should be appreciated that the specific embodiments described herein are only used to explain that this is practical It is novel, it is not used to limit the utility model.

Embodiment

Small silent triple valve as shown in Figure 1 is by valve body, fixed spool, O-ring, coil holder, coil, gasket A, activity Spool, gasket B, spring, end cap composition are equipped with interface 1, interface 2, interface 3, flow mouth A and flow mouth B.

Wherein fixed spool be 2. arranged in the valve body 1. on, coil holder be embedded in valve inner, O-ring 3. with the coil holder 4. Be socketed on the fixed spool 2. on, for sealing the fixed spool, 4. 5. periphery is wound with coil to the coil holder, the coil holder 4. it is internal be cased with can on-off air-flow the movable valve plug, 7. 6. upper end is stained with gasket A to the movable valve plug, and lower end is stained with close 8. packing B, forms flow mouth A and flow mouth B at gasket A, B respectively, 10. 1. the end cap is bolted to valve body On, 10. 4. the end cap uses O type circle to seal (not shown) with the coil holder.

The movable valve plug and the gasket of fixed spool cooperation are higher by 1mm than movable valve plug surface, logical in coil In the case where electricity, so that movable valve plug and fixed spool is not issued metal strike sound when being attracted, achieve the effect that mute；Coil holder Interior to have through-hole, movable valve plug is embedded, and in order to allow the flow to pass through, movable valve plug is what two sides were scabbled in the present embodiment Cylinder is also possible to polygon；The end cap is bolted on valve body, and detachable maintaining can be made more convenient.

When being mounted to normal-open electromagnetic valve, in coil no power, interface 1 leads to medium, since gasket A is in bullet Spring precompressed elastic force acts on lower and metering orifice A from a distance, and interface 1 and interface 2 communicate；In the case of coil is powered, moving valve Core overcomes the elastic force of spring to be fixed spool actuation under the action of electromagnetic force, and metering orifice A is closed by gasket A, and metering orifice B is opened It opens, interface 2 and interface 3 are flowed out without medium.

When being mounted to normal-closed electromagnetic valve, in coil no power, interface 3 leads to medium, since gasket B is in bullet Spring precompressed elastic force acts on the metering-orifice B closing that flows down, and interface 1 and interface 2 are flowed out without medium；In the case of coil is powered, movable valve plug exists The elastic force of spring is overcome to be fixed spool actuation under the action of electromagnetic force, metering orifice A is closed by gasket A, and metering orifice B is opened, Interface 2 and interface 3 communicate.

By using above-mentioned technical proposal disclosed by the utility model, following beneficial effect has been obtained:

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching should also regard the protection scope of the utility model.
