Description
Technical field
The utility model relates to a kind of electricity consumption to be operated and cuts off the mobile repeatedly used emergency switching-off solenoid valve of fluid (gas or liquid).
Background technique
Fluid delivery system is widely used in fields such as Aero-Space, sea-freight, petrochemical industry, rock gas, coal gas, and in recent years, the medical gas supply system is also progressively equipped by hospital.
Because application difference, these fluids may be poisonous, inflammable and explosive or pressure is very high, in case have an accident, may cause the heavy losses or the pollution in wide area of personnel and property, even nontoxic gas also may cause adverse consequences, with the HC oxygen system that day by day increases is example, present most ward and operating room are equipped with pipeline, supply with oxygen by the central oxygen station, originally be patient and alleviate the blue-collar good facility of medical care personnel for convenience, but it is very wide that pipeline distributes, pipeline is very long, in case because of the other reasons breaking out of fire, burn out oxygen channel or oxygen supply terminal, have and press the ejection of oxygen then really to pour oil on the fire, may cause major disaster.
Avoid the fluid transport process to break down, at present only way is to prevent escape of liquid by every means, and establishes safety installations such as safety valve, reflux valve on pressure line, makes system pressure be no more than the pressure that pipeline and equipment can bear; Simultaneously can establish alarm system, leak in case produce, send alarm signal by safety system behind the sensor sensings such as relevant smog, concentration, temperature, prompting the related personnel take measures, or discharge pressure or throttle down, or start fire-fighting system.In these measures, discharge pressure is to poisonous automatically, and inflammable, combustion-supporting fluid is very limited; For " throttle down ", be manual operation at present, mode is to close corresponding stop valve to stop to flow of fluid.Because story height, distance, reason such as the disaster area condition is abominable, manual operation often affects opportunity adversely, or unfeasible, causes disaster further to enlarge.
Summary of the invention
The purpose of this utility model provides a kind of in case of emergency can electricity consumption the operation and cuts off the mobile repeatedly used emergency switching-off solenoid valve of fluid (liquid or gas).

The utility model has the advantages that:
1, the repeatedly used emergency switching-off solenoid valve of the utility model, it is stuck in the annular groove of valve alive side by a position-limited lever, makes valve alive be in the position of long-term unlatching with simple mechanical means, needs only position-limited lever and does not pull out, the valve of living just can not cut out, not only simply but also reliable.
2, the repeatedly used emergency switching-off solenoid valve of the utility model; it withstands the motion of control position-limited lever with an auxiliary spring; because position-limited lever is stuck in the annular groove of valve alive side; and the matching gap of live valve and valve body is very little; therefore, as long as position-limited lever blocks very small size, the valve of can guaranteeing to live can not move; just the spring force of auxiliary spring need not very greatly, and then can reduce the suction and the size of electromagnet.
3, the repeatedly used emergency switching-off solenoid valve of the utility model, the valve of wherein living are under the effect of main spring and close, and be irrelevant with hydrodynamic pressure, this simple, reliable by the live method of valve of spring mechanical driving.
4, the repeatedly used emergency switching-off solenoid valve of the utility model, wherein positioning rod can related valve alive to left movement, when valve is in opening state, the positioning rod and the valve of living have the gap between axially, both do not contact mutually, can guarantee valve under normally open, positioning rod can not disturb valve alive; When living valve in off position down, positioning rod can not run into valve alive yet, the sealing effect of the valve that can guarantee to live, that is: in the electromagnet energising, when position-limited lever is extracted, positioning rod can not catch on valve alive and the valve that causes living bumps not upper valve base, valve can not be closed tight.In addition, when positioning rod was positioned at outermost end, position-limited lever just in time snapped in the annular groove, therefore can not cause that the position-limited lever distortion causes valve alive stuck because of being pulled outwardly positioning rod.
5, the repeatedly used emergency switching-off solenoid valve of the utility model, it can be worked repeatedly, the shortcoming that must change when having overcome the disposable use of present many safety installationss, system recovery, and because the test of can regularly switching on, the test back restores to the original state, and has improved the operability and the reliability of whole safety system.
6, the repeatedly used emergency switching-off solenoid valve of the utility model remains on opening state with mechanical means at ordinary times always, need not electricity consumption.Be used for safety system with one, need electricity consumption to realize that the valve of control is compared automatically, do not need to power year in year out, the energy of its consumption seldom; In addition, when this solenoid valve will work (cutting out) because of urgency, only need instantaneous energising to get final product in 1~2 second, energy consumption is very little.
