Coil can produce magnetic field after the energising, is wound in the periphery of aforementioned sleeve,
It is characterized in that described return unit is one to be sheathed on the Returnning spring of described moving iron core rearward end, the stepped part of this Returnning spring rear end and described moving iron core offsets, and front end and described socket port offset.
The top of described moving iron core forms a groove, is embedded with a cushion pad in the groove.At first can play buffer function, can reduce moving iron core material in addition, reduce requirement electric power.
Further, described gas joint group spare comprises
Following assembly has a gas-entered passageway and one first outlet passageway;
Last assembly is positioned at aforementioned assembly down top, and is sealed and matched with aforementioned assembly down, has second outlet passageway by described moving iron core keying;
The aforesaid gas-entered passageway and first outlet passageway are a straight line, and vertical with aforesaid second outlet passageway.
Influence the proper functioning of solenoid valve for preventing that gas from flowing backwards, to be provided with a safety check that is used to stop described second outlet passageway refluence between described assembly down and the last assembly.
As preferably, the first step face that the described upper-end surface of assembly down has a spill, the second step face that described lower end surface of going up assembly also has a spill, aforesaid first step face and second step face are combined into a holding cavity, and described safety check then is located in this holding cavity.
Described valve seat is provided with the support of U-shaped substantially at right angles outward, and this support port is provided with both sides and all offers positioning hole, the positioning part, both sides of a cover plate be inserted in the aforesaid positioning hole and with described valve seat fixed limit on aforementioned brackets.
For reducing manufacture cost, described coil adopts aluminum coil.
Compared with prior art, advantage of the present utility model is: because Returnning spring is located at the bottom, do not influence front end circumferentially with the magnetic face area of static iron core, reasonable in design, therefore lower to the electric power requirement that drives moving iron core motion; The cushion pad setting further reduces the electric power requirement; Safety check can prevent that the gas refluence from influencing the phenomenon generation of the proper functioning of solenoid valve.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 5, the low-voltage solenoid valve in the present embodiment is mainly used in the low voltage control of sports equipment as Fig. 1, specifically comprises valve seat 1, safety check 8, support 3, gas joint group spare 2, static iron core 6, moving iron core 5, Returnning spring 51 and coil 4,
Valve seat 1 has a sleeve 11, has a movable cavity 12 for moving iron core 5 activities in this sleeve 11; Support 3 is located at outside the valve seat 1, right angle U-shaped substantially, these support 3 ports be provided with that positioning part, both sides that both sides all offer positioning hole 32, one cover plates 31 is inserted in the positioning hole 32 and with valve seat 1 fixed limit on support 3.
