Accompanying drawing explanation
Fig. 1 describes the schematic diagram being connected with gas pipeline with gas cylinder according to the solenoid valve of specific embodiment of the utility model.
Fig. 2 describes according to the structural representation of the solenoid valve of specific embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, describe according to embodiment of the present utility model.Fig. 1 is the schematic diagram that a kind of guide electromagnetic valve of providing according to the utility model is connected with gas pipeline with gas cylinder, and as described in Figure 1, this solenoid valve 1 is connected between gas cylinder 20 and gas pipeline 2.
Fig. 2 is according to the structural drawing of the solenoid valve of specific embodiment of the utility model.As shown in Figure 2, solenoid valve 1 comprises the first valve body 12 and second valve body 13 of valve operation unit 11, column.Wherein, valve operation unit 11 comprises spool 110 and coil block 111.One end of the first valve body 12 is connected with the outlet side (not shown) of the cylinder valve 21 (shown in Fig. 2) of gas cylinder 20, one end of the second valve body 13 is communicated with gas pipeline 2, the other end of the first valve body 12 and the second valve body 13 is connected to each other and forms an inner chamber 121, valve operation unit 11 is positioned at the connecting part of the first valve body 12 and the second valve body 13, and the spool 110 of valve operation unit 11 is placed in inner chamber 121.There is such structure, the measure of a kind of safe opening/closing gas cylinder to gas pipeline air feed is provided, even if in case of emergency also can close rapidly, safely air feed.
In solenoid valve 1, the medial axis of the first valve body 12 is perpendicular to one another with the medial axis of the second valve body 13, and the medial axis of valve operation unit 12 overlaps with the medial axis of the second valve body 13.
The first valve body 12 is with internal thread union 122, and the screw-thread fit by internal thread union 122 is connected the first valve body 12 with the outlet side (not shown) of the cylinder valve 21 (shown in Fig. 2) of gas cylinder 20.The inlet side of the first valve body 12 is as the inlet side of whole solenoid valve 1, and the outlet side by internal thread union and gas cylinder 20 is tightly connected.Conventionally, gas cylinder 21 is all with cylinder valve 21 (shown in Fig. 2), and therefore the now outlet of cylinder valve 21 is as the outlet side of gas cylinder 21.By the linkage structure with internal thread union, the main body 1 (valve operation unit 11 is upper) of solenoid valve 1, perpendicular to horizontal plane, is tightened.Solenoid valve 1 joint plane (air inlet end face) can also comprise seal ring 121, with effectively, be connected with the outlet side plane sealing of cylinder valve reliably.By the linkage structure with internal thread union, can make the main body of solenoid valve 1 locate in arbitrary position, and the axle center of guaranteeing coil block is all the time perpendicular to horizontal plane, solenoid valve 1 can normally be worked.By such design, it is easy that the installation of solenoid valve 1 will become, and flexibility grow, and the difference that is applicable to all size vehicle under the prerequisite that guarantees normal work is installed occasion.
The second valve body 13 of solenoid valve go out end, as the end that goes out of solenoid valve, by connecting bolt 30, cutting ferrule 31, be connected with pipeline 2.
The spool 110 of the valve operation unit 11 of solenoid valve 1 moves along the medial axis direction of coil block 111 and the second valve body 13.
Solenoid valve is pilot-type solenoid valve, is normally off.As shown in Figure 2, valve operation unit 11 comprises spool 110, coil block 111, fixed core 112, spring 113.Spool 110 comprises guide's spool 1101 and main valve plug assembly 1102
Coil block 111 energisings in valve operation unit 11 produce behind magnetic field, by fixed core 112, produce magnetic force, magnetic force pulls guide's spool 1101 micro-main valve plug assembly 1102 that opens subsequently, make after pilot hole (not shown) conducting, reach that main valve plug assembly 1102 opens entirely, solenoid valve 1 opens, i.e. the complete conducting of inner chamber of the inner chamber of the first valve body 12 and the second valve body 13.
Under the closed condition of solenoid valve, main valve plug 1102 can be blocked the opening of the second valve body 13 in inner chamber hermetically, thereby the compressed natural gas that the first valve body 12 flows into will be plugged to the mobile of the second valve body 13, then cannot flow ipe 2 in.When cutting off the electricity supply, because of the return action of spring 113, guide's spool and main valve plug are pushed to reset, and solenoid valve 1 cuts out.
The joint of main valve plug 1102 and the second valve body 13 can also add seal ring, to guarantee good tightness.
Concrete structure according to solenoid valve of the present utility model has more than been described.But the concrete structure of relevant each several part is also not limited to above-described embodiment, can do various changes in the scope that does not depart from the utility model aim.
