Description
Technical field
This utility model relates to industrial equipment field, is specifically related to a kind of anti-gas-leak electromagnetic valve.
Background technology
Conventional electromagnetic valve has been provided with closed chamber, and annular seal space diverse location has through hole, and each through hole leads to different oil pipes or trachea, spool is set in the middle of chamber through hole is carried out break-make, cavity side is provided with electric magnet, by electric magnet, spool is controlled, thus controlling the break-make of through hole.And existing electromagnetic valve is all respectively provided with through hole contact position at spool and coordinates inclined-plane, is contacted by face and reaches sealing effectiveness.
On natural gas equipment, electromagnetic valve is conventional natural gas valve, and owing to natural gas equipment has relatively atmospheric pressure, natural gas impulsive force is big, and the spool of electromagnetic valve often deflection occurs owing to natural gas impacts.Due to the sealing means of electromagnetic valve practicality face contact, cannot playing sealing effectiveness after spool deflection, gas leakage is serious, not only shortens the life-span of electromagnetic valve, there is also very big potential safety hazard.
Utility model content
In view of this, the open a kind of anti-gas-leak electromagnetic valve of this utility model.
The purpose of this utility model is achieved through the following technical solutions:
nullA kind of anti-gas-leak electromagnetic valve，Including valve body，Described valve body is provided with venting cavity and lower venting cavity and the airway of the upper venting cavity of connection and lower venting cavity，Airway is surrounded with sealing inclined-plane towards the side of upper venting cavity，Described upper ventilation connects gas outlet，Described lower venting cavity connects air inlet，It is provided with iron core valve between described upper venting cavity and lower venting cavity，Described upper venting cavity upper end is provided with electric magnet，It is provided with bottom described electric magnet and holds the sliding tray that iron core valve slides up and down，Described iron core valve is provided with the passage extending vertically through iron core valve，Described iron core valve is arranged above buffer stopper，Described buffer stopper is provided with dashpot，It is provided with, in described dashpot, the Elastic valve core that can slide up and down，The elastic circular arc termination mated with passage it is provided with bottom described Elastic valve core，It is provided with bottom described iron core valve and seals the electromagnetism circular arc termination mated on inclined-plane.
Utility model works principle is as follows:
Gas enters lower venting cavity by air inlet, realizes break-make by magnet control iron core valve between upper venting cavity and lower venting cavity.Gas has portion gas by passage when impacting bottom iron core valve, now the Elastic valve core in dashpot is produced micro-strain by gas punching press, and release portion gas is in sliding tray, and due to air pressure, the gas in sliding tray can flow into venting cavity.The setting of passage, buffer stopper and Elastic valve core, effectively turns on gas in the middle part of iron core valve, and buffer gas impulsive force, thus preventing iron core valve deflection, it is ensured that sealing effectiveness.Elastic valve core arranges elastic circular arc termination, iron core valve arranges electromagnetism circular arc termination, by the contact of incline plane of arc surface Yu relevant position, original face contact type is sealed and is changed into line contact type sealing, even if Elastic valve core and iron core valve produce deflection also can play good sealing effectiveness.
Further, buffering pore also it is vertically installed with bottom described Elastic valve core.
Buffering pore is set bottom Elastic valve core, effectively alleviates the direct impulsive force of gas, it is prevented that Elastic valve core offsets.
Further, described dashpot is provided with spring connection Elastic valve core.
The beneficial effects of the utility model are in that:
This utility model simple in construction, stability is high, good sealing effect, effectively prevent electromagnetic valve and leaks air situation, extends the life-span of electromagnetic valve.
