Description
Technical field
The utility model relates to solenoid valve, is specifically related to a kind of high-pressure solenoid valve of docking with pressure reducing regulator.
Background technique
Solenoid valve (Electromagnetic valve) is the industry equipment by Electromagnetic Control, is used to the automation foundation element controlling fluid, belongs to final controlling element, is not limited to hydraulic pressure, pneumatic.Be used in industrial control system adjust medium direction, flow, speed and other parameter.Solenoid valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system, and the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc.
High-pressure solenoid valve is applicable to the control of compressed natural gas used as vehicle fuel (CNG), and its rated working pressure is 20MPa.High-pressure solenoid valve is assembled together with pressure reducing regulator, matching used.Sealing means when current high-pressure solenoid valve is connected with pressure reducing regulator generally adopts red copper gasket seal, as shown in Figure 1, a kind of high-pressure solenoid valve, comprise valve body 6, this valve body comprises the portion of giving vent to anger 5 of annular, the sidewall in the portion of giving vent to anger of this annular has the head piece 7 be excessively communicated with high pressure valve primary valve, and high-pressure solenoid valve also comprises:
Two red copper pads 4, lay respectively at relative both sides, the portion of giving vent to anger;
Joint 8, for being connected with reduction valve, the end of joint and one of them red copper pad against, and towards the side in the portion of giving vent to anger, there is tapped hole;
Sealing screw rod 1, wherein one end is each passed through two red copper pads and tapped hole screw-thread fit, and sealing screw rod has vent 3 in the axial direction, and has with mistake head piece corresponding position the attachment hole 2 be communicated with vent.
When this high-pressure solenoid valve uses, pressurized gas enter from the entrance (not drawing Fig. 1) of solenoid valve, and when the coil electricity of high pressure valve, primary valve is opened, pressurized gas entered joint after passing through head piece, attachment hole and vent successively, finally entered reduction valve.
Environmental Conditions temperature due to high pressure valve is-40 DEG C ~ 120 DEG C, the impact of high/low temperature and vehicle strenuous vibration in motion, and sealing place of red copper pad can be made to occur leaking.As everyone knows, rock gas is a kind of dangerous gas, produces the deadly defect that leakage is pressure reducing regulator, very easily causes the generation of security incident.
