Abstract
The invention discloses a medical sealed fire-control safety suction and pull switch. Due to the arrangement of a glass-shell dry reed diode in a shell, the medical sealed fire-control safety suction and pull switch has the characteristic that the glass-shell dry reed diode can realize the connection of control lines during equipment start and stop control and avoid the electrical arc and the danger during equipment start and stop; due to the arrangement of a low-power relay on the lower end of the glass-shell dry reed diode, the medical sealed fire-control safety suction and pull switch has the characteristic that the low-power relay can be used to directly start a high-power contactor through the normally opened contact and normally opened contact per se when control equipment has large capacity; and in addition, due to the arrangement of a guide rod cylinder on one side end of the shell, the arrangement of a circular magnet in the guide rod cylinder, and the arrangement of a push rod on the lower end of the circular magnet, the medical sealed fire-control safety suction and pull switch has the characteristic that the push rod can be directly inserted into the guide rod cylinder during control equipment start, and after the circular magnet is pre-pressed to be near to the glass-shell dry reed diode, a moving contact in the glass-shell dry reed diode can be sucked so as to be connected with a static contact.
Description
Technical fieldThe present invention relates to fire-fighting, directly relate to medical sealed type security against fire suck-pull switch, adapt to inflammable and explosive and other inflammable and explosive unsafe occasion use especially in hospital.
Background technologyIn Equipment Control, will use disconnecting link, button control contactor to wait the starting and stopping that realize equipment, control switchs such as disconnecting link, button, contactor are convenient and practical to be adopted by people are extensive always; People find that also existing disconnecting link, airtight start-stop connect button in long-term the use, because of being subject to expose to the weather for a long time, to airtight performance is reduced, have particularly operated the stopping time to be prone to electric arc and spark phenomenon, very easily can bring the danger of blast to the place.
Summary of the inventionThe present invention will provide a kind of medical sealed type security against fire suck-pull switch exactly; It can overcome effectively: be subject to for a long time expose to the weather because of disconnecting link, airtight start-stop connect button etc.; To airtight performance is reduced; Particularly having operated the stopping time is prone to electric arc and spark phenomenon, very easily can bring the drawback of explosion hazard for the place.
The objective of the invention is to realize like this: medical sealed type security against fire suck-pull switch, have housing and pushing ram, the dried spring diode of glass bulb is set in the said housing; The dried spring diode of glass bulb lower end is provided with low power relay; Housing one side is provided with the guide rod tube, and round magnetite is set in the guide rod tube, and round magnetite lower end is provided with pushing ram; The pushing ram bottom is provided with ring, and housing bottom is provided with lock ring.
The present invention is provided with the dried spring diode of glass bulb owing to having adopted in housing, its characteristics are: when the equipment start-stop was controlled, the dried spring diode of glass bulb was realized and can be connected control circuit, electric arc and danger can not occur in the time of also can realizing start-stop work.
The present invention is provided with low power relay owing to having adopted in the dried spring diode of glass bulb lower end again, and its characteristics are: when the control appliance capacity was big, low power relay is realized can be through self normally opened contact and the more high-power contactor of normally-closed contact across-the-line starting.
The present invention also is provided with the guide rod tube owing to having adopted at housing one side; Round magnetite is set in the guide rod tube; Round magnetite lower end is provided with pushing ram, and its characteristics are: when required control appliance started, pushing ram was realized and self directly can be inserted the guide rod tube; Round magnetite realize self being subjected to roof pressure and the dried spring diode of glass bulb near after, can will make itself and the conducting of stationary contact institute under the movable movable contact suction in the dried spring diode of glass bulb.
The present invention also is provided with ring owing to having adopted in the pushing ram bottom again; Housing bottom is provided with lock ring; Its characteristics are: after pushing ram promotes round magnetite and inhales movable movable contact and the stationary contact conducting in the moving dried spring diode of glass bulb, pushing ram can be pinned whom to ring and lock ring realization and can not go to operate.
Description of drawingsAccompanying drawing is the structure principle chart of the medical sealed type security against fire of the present invention suck-pull switch, below in conjunction with accompanying drawing the present invention is further described.
EmbodimentAccompanying drawing shows knot of the present invention; The dried spring diode 2 of glass bulb is set in the housing 1, and the dried spring diode of glass bulb 2 lower ends are provided with low power relay 3, and housing 1 one sides are provided with guide rod tube 4; Round magnetite 5 is set in the guide rod tube 4; Round magnetite 5 lower ends are provided with pushing ram 6, and pushing ram 6 bottoms are provided with ring 7, and housing 1 bottom is provided with lock ring 8.
Use of the present invention is: at first housing 1 is fixed on the operation site appropriate location; When equipment need start, operating personnel can hold pushing ram 6 and directly insert guide rod tube 4, and this moment, pushing ram 6 tops sucked and round magnetite 5; Pushing ram 6 promotes round magnetite 5 to be continued to push ahead; When treating that round magnetite 5 is pressed close to the dried spring of glass bulb diode 2, round magnetite 5 can be inhaled the moving contact 9 in the dried spring diode 2 of glass bulb down moving contact 9 and fixed contact 10 conductings; Control lead-in wire 11 starts low power relay 3, low power relay 3 control lead-in wires 12 start-up control equipment contactors.When control appliance is out of service; Operating personnel can hold pushing ram 6 and directly in guide rod tube 4, pull out; When round magnetite 5 retreats to the 4 bottom reducings of guide rod tube; Round magnetite 5 promptly can adsorb automatically with the metal plate of guide rod tube 4 bottom reducings (indicating) on, at last pushing ram 6 is withdrawed from guide rod tube 4 and recognizes and deposit.
Handle 9 advances inwards, and pushing ram front end magnetite 8 is near tongue tube 6, and magnetite 8 can pull to fixed contact 11 with moving contact 10 in the tongue tube 6, and this moment, 12 conductings of Equipment Control lead started required control appliance.When institute's control appliance stopped, operating personnel can hold and advance handle 9 outwards to pull out, and magnetite 8 breaks away from tongue tube 6, automatic rebound reset behind moving contact 10 losss of excitation, and instant Equipment Control lead 12 breaks off, and required control appliance stops.For preventing that not operation personnel operation suck-pull switch is directed at equipment and misoperation occurs, also can use lockset 13 will advance handle 9 to lock the jail with member lock ring 14 after the shutdown.
