Abstract
The utility model relates to a button and a switch of a flame-proof type tongue tube, which is characterized in that the tongue tube is taken as a control element of the button and the switch; the magnetic force of a magnet is taken as the external control force of a contact of the tongue tube; the tongue tube can adopt high vacuum type or inert gas filling type; spark generated by the contact when a control circuit is switched on the on-off state is sealed in the tube body of the tongue tube, and is enabled to be isolated from explosive gas and coal dust completely; and the purpose of preventing explosion and improving safety factor is achieved. The button and the switch of the flame-proof type tongue tube are suitable for mines with explosive gas and coal dust and hazardous sites with explosive gas, such as factories, ships and the like, and used for controlling intrinsically safe control circuits and non intrinsically safe control circuits.
Description
Affiliated technical field
The utility model relates to a kind of flame-proof type tongue tube button and switch, be applicable to the mine that contains damp and coal dust, and the hazardous area such as factory, boats and ships of containing damp, be used as the usefulness of the control of essential safe type control circuit and non-intrinsically safe safety-type control circuit.
Background technology
At present, employed control button and switch mostly are air type in having damp and coal dust environment, its contact spark directly contacts with air, though these buttons and switch have all been equipped explosion-resistant enclosure, but because therefore easy ageing failure of explosion-resistant enclosure parts and maintenance careless omission still exist potential safety hazard.
Summary of the invention
In order further to improve the fail safe that the hazardous area produces, the utility model is according to the needs of circuit control operation mode, flame-proof type tongue tube button and flame-proof type dry-reed tube switch have been designed respectively, both are control element with dry type tongue spring tube (hereinafter to be referred as " tongue tube ") all, with the magnetic force of the magnet control external force as reed switch contact.Tongue tube can be high vacuum formula or inert gas filled type, and the spark that the contact produces during with the control circuit break-make is enclosed in the pipe shaft of tongue tube, and it is completely cut off with damp and coal dust fully.
The technical solution of flame-proof type tongue tube button is in the utility model: tongue tube is inserted in the water droplet shape pore of push-button socket, the electrode of tongue tube is guided to respectively on the binding post on top, push-button socket two ends and is screwed, and the inlet of pore fixes body with the epoxy resin embedding.The button support is the extension connector of push-button socket, is positioned at the push-button socket top, and the side becomes 7 fonts.Button spindle passes the button spindle support after being inserted in spring, its lower end is connected with rectangle magnet suspended block, magnet is positioned at the both sides of magnet suspended block, the top of reed switch contact, and keep certain distance with tongue tube, it is moving that this distance can not be inhaled reed switch contact by magnetic force, and magnet is pressed close to reed switch contact when pressing the button bar, magneticaction attracts the reed switch contact action, electrode is connected or disjunction, and when decontroling button spindle, spring resets button spindle jack-up, magnet is attenuated to level before to the magneticaction of contact, the contact is broken away from magnetic force and is resetted, and makes electrode disjunction or connection, so reaches the purpose of control circuit.Button packed into can realize duplicate protection behind the solid explosion-resistant enclosure.
The technical solution of flame-proof type dry-reed tube switch is in the utility model: switch main body is a round barrel shape, the water droplet shape pore that bucket wall right-hand member has branch such as some circumference to arrange, and left end has shrouding, and there is annular corrugated positioning convex the shrouding inboard, at the center of corrugated positioning convex mesopore is arranged.Tongue tube is inserted in the pore on the switch main body, and the electrode of tongue tube is guided to respectively on the binding post at switch main body two ends and is screwed.The switch rotating shaft penetrates Magnmet rotor and is connected as a single entity, and Magnmet rotor is cylindrical, and the magnet slotted eye that right-hand member has branch such as some circumference to arrange is put into corresponding magnet slotted eye according to the design needs with magnet, with epoxy resin embedding fixed magnet.And positioning key and retainer spring are put into two positioning key slotted eyes of Magnmet rotor left end, again the Magnmet rotor that assembles are put into switch main body, and switch rotating shaft tail end is passed in the mesopore of switch main body left end.Switch panel is contained in the right-hand member of switch main body, and the mesopore of switch panel is passed in the switch rotating shaft, and Magnmet rotor is enclosed in the switch main body.At last switch knob is contained in switch rotating shaft right-hand member top, with screw.The rotating switch handle, positioning key is pushed the recess of corrugated positioning convex by spring, make magnet slotted eye on the Magnmet rotor always be positioned at the correspondence position of tongue tube on the switch main body, when being placed with magnet in the magnet slotted eye, just can attract corresponding reed switch contact action, the reed switch contact of correspondence is failure to actuate when the magnet slotted eye is vacant, by to the vacant of magnet slotted eye and placement layout, just can design the control mode that needs.Whole switch packed into can realize duplicate protection behind the solid explosion-resistant enclosure.
Two or more flame-proof type dry-reed tube switch is contacted from beginning to end, just can increase controlled function.The flame-proof type dry-reed tube switch can also use with flame-proof type tongue tube button combination, to finish more complicated Control work.
The beneficial effects of the utility model are, the spark that is produced during the reed switch contact break-make is enclosed in the tongue tube, completely cut off with damp and coal dust fully, pack into behind the solid explosion-resistant enclosure, coefficient of safety is higher, produce saferly, essential safe type control circuit and non-intrinsically safe safety-type control circuit all can use.And longer because of the mechanical endurance and the electric life of tongue tube, can reduce the input and the maintenance cost of equipment.
