Description
Technical field
The utility model relates to stop valve field more particularly to a kind of dynamic iron cores.
Background technique
Gas control valve is a kind of solenoid-operated proportional system of movable permanent magnet type, and PC main controller passes through user setting temperature
Four degree, inflow temperature, flow of inlet water and leaving water temperature input variables export electric current, magnetic field are generated in coil by operation
Power pushes ball valve to move up and down, adjusts the breathing area of valve port, constantly carry out subtle step-less adjustment to gas flow, make
User setting temperature keeps stablizing, and the valve arrangement is simple, reliable performance, adjusts sensitive.Stop valve is can not in gas control valve
One of component lacked, stop valve is interior to be equipped with dynamic iron core, utilizes the principle of electromagnet, and when stop valve is powered, dynamic iron core is generated
Magnetic force is attracted, to make to cut off valve events.Dynamic iron core in the prior art is pressed into solid construction using soft magnetic materials cold forging,
A piece dynamic iron core needs to expend more soft magnetic materials, at high cost, and solid construction is but also iron core quality weight, in use, cutting
Valve needs to consume more electric energy could pull-core；Cold forging pressing process is cumbersome, reduces production efficiency, is unfavorable for enterprise's drop
Low production cost.
Utility model content
The purpose of this utility model is to provide a kind of light-weight, convenient for production, inexpensive dynamic iron cores.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of dynamic iron core, including hollow soft magnetism cylinder and injection molding body, the injection molding body is hollow column structure, column
The upper top surface of shape structure is equipped with the upper overturning outwardly protruded, and the bottom surface of column structure is equipped with the lower flange outwardly protruded, soft magnetism
Cylinder is set in the outside of injection molding body, and soft magnetism cylinder is clamped between upper overturning and lower flange.
Further, the upper width of the injection molding body inner wall is greater than the lower width of inner wall.
Further, the bottom of the injection molding body is equipped with the extension that width is less than column structure, extension and column knot
Structure is integrally formed, and the bottom surface of extension extends outward to form chuck.
Further, the soft magnetism cylinder is rolled by soft magnet plate.
Under the premise of meeting magnetic force size, by magnetic made of former solid construction soft magnetic materials
Core is designed to hollow structure, reduces the usage amount of soft magnetic materials, while reducing cost, also reduces the weight of dynamic iron core,
So that the operating current of electromagnet is reduced and reaches energy-efficient purpose；Injection molding body is located at soft magnetism column body, to hollow knot
The soft magnetism cylinder of structure plays good supporting role, while injection molding body upper and lower end parts outwardly protrude to form flange, and dynamic iron core is inhaled
When conjunction, flange forms protection to the end face of soft magnetism cylinder.
Detailed description of the invention
Fig. 1 is one dynamic iron core cross-section diagram of embodiment；
Fig. 2 is two dynamic iron core cross-section diagram of embodiment；
Label declaration
Soft magnetism cylinder 1, injection molding body 2, upper overturning 3, lower flange 4, extension 5, chuck 6, deck 7.
Specific embodiment
Present invention is further described in detail with reference to embodiments.
Embodiment 1:
The present embodiment proposes a kind of dynamic iron core, as shown in Figure 1, the dynamic iron core includes hollow soft magnetism cylinder 1 and injection molding
Body 2, soft magnetism cylinder 1 are rolled by soft magnet plate, and soft magnet plate is silicon steel sheet in the prior art, have magnetic conductivity good, punching is good
Feature.Injection molding body 2 is hollow column structure, and the upper top surface of injection molding body 2 is equipped with the upper overturning 3 outwardly protruded, under injection molding body 2
Bottom surface is equipped with the lower flange 4 outwardly protruded, and soft magnetism cylinder 1 is set in the outside of injection molding body 2, and soft magnetism cylinder 1, which is clamped in, to be turned over
Between side 3 and lower flange 4.The setting of injection molding body 2 provides necessary support for hollow soft magnetism cylinder.It is attracted in dynamic iron core
During, dynamic iron core can constantly hit static iron core, and dynamic iron core can be effectively protected in the design of upper overturning 3 and lower flange 4,
Dynamic iron core is prevented to be damaged in knockout process.Hollow 2 light weight of injection molding body, greatly alleviates the weight of dynamic iron core,
Dynamic iron core is easily attracted under low current, so that the stop valve using the dynamic iron core is more energy saving, and Shooting Technique
It is simple and convenient, the production efficiency of enterprise can be effectively improved, production cost is reduced.For the ease of the reset of dynamic iron core, generally
Need to be arranged reset spring (not shown), the upper width of 2 inner wall of injection molding body is greater than the lower width of inner wall, forms one
For installing the deck 7 of reset spring.
Embodiment 2:
The construction of embodiment 2 is similar to Example 1, as shown in Fig. 2, being different from 1 place of embodiment are as follows: the note of the dynamic iron core
2 bottom of plastomer is equipped with the extension 5 that width is less than column structure, and extension 5 and column structure are integrally formed, the bottom of extension 5
It extends outwardly to form chuck 6, reset spring is arranged at extension 5, and reset spring is by chuck 6 and the clamping compression of lower flange 4.
