Abstract
The utility model discloses an electromagnetic closing valve of the fuel gas leakage, comprising a valve, a valve handle, a valve patch and an electromagnetic pin. An automatic cutoff is added to the electromagnetic pin. When the valve is closed, the power supply of an electromagnetic loop is cut off automatically. The insecure factors caused by the long time switching on of the electromagnetic loop are avoided. The utility model can coordinate with a controller of fuel gas leakage, used for the alarm of the fuel gas leakage and the automatic break of the gas source of the civil pipeline.
Description
The utility model relates to the gas pipeline valve, and the particularly electromagnetism cut-off valve of fuel tube is mainly used in the autocontrol switch of domestic gas pipeline.
Along with improving constantly of people's lives, domestic gas is more and more universal, and the poisoning that causes owing to its leakage in the use of combustion gas, fire and explosive accident also happen occasionally.In order to prevent this type of accident, I disclose a kind of gas leakage safety governor in the patent of patent No. ZL93213689.3, utilize gas security to control the electromagnetic valve of gas pipeline automatically, promptly when gas leakage, the solenoid valve adhesive makes the valve pad in the valve body close blast tube, if recover ventilation again, then must operate by the people.Though this valve can be closed source of the gas effectively, also there is deficiency, promptly after closing source of the gas, the electromagnetic coil loop of its solenoid valve can not disconnect, if the combustion gas emptying in time of leaking in the environment, then electromagnetic coil can be in powering state always, makes its heating produce unsafe factor.
The purpose of this utility model just provides a kind of gas leakage electromagnetism cut-off valve that can cut off the electromagnetic coil loop when closing automatically.
The technical solution of the utility model is: the utility model comprises valve body, the valve body support, valve rod electromagnetism pin, the valve body support is vertically connected on a side of valve body, stem position is slidingly matched in the center hole of valve body support and with it, at the middle part of valve rod one draw-in groove is arranged, there is a through hole position at the corresponding described draw-in groove of valve body support, pass above-mentioned through hole with the narrow neck end of the adhesive pin of valve body support electromagnetism pin connected vertically and be positioned at draw-in groove, also has a power breaker in the bottom of described electromagnetism pin, comprise pedestal, the adhesive pin rod, the movable contact spot film, prop up spring, movable contact, stationary contact, adhesive pin rod and the coaxial center hole that links to each other and pass pedestal in the bottom of adhesive pin, pedestal links to each other with the bottom of electromagnetism pin, the tail end that connects the movable contact spot film at its back side on one side, another side has stationary contact, it is facing to the movable contact of movable contact spot film head end, middle part, the back side at the movable contact spot film is a spring, and the end of adhesive pin rod is facing to the middle part of movable contact spot film.
Described electromagnetism pin comprises electromagnetic coil, spring, adhesive pin, spring pedestal, adhesive pin, spring, spring pedestal place the center hole of electromagnetic coil successively, and the adhesive pin rod that is connected with the bottom of adhesive pin passes the spiral hole of spring and the center hole of spring pedestal.
One insulating boot is arranged outside described power breaker; At the back side of described movable contact one limiting stopper is arranged.
The utility model has the advantages that: can when closing gas pipeline, cut off the loop of electromagnetic coil, stop unsafe factor, simple in structure, reliable performance owing to the coil heating generation.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Referring to Fig. 1, the utility model comprises valve body 1, valve body support 4, valve rod 5, the electromagnetism pin, valve body support 4 is vertically connected on a side of valve body 1, valve rod 5 is positioned at the center hole of valve body support 4 and is slidingly matched with it, one draw-in groove 8 is arranged at the middle part of valve rod 5, there is a through hole 22 position at valve body support 4 corresponding described draw-in grooves 8, pass above-mentioned through hole 22 with the narrow neck end 21 of the adhesive pin 10 of valve body support 4 electromagnetism pins connected vertically and be positioned at draw-in groove 8, also has a power breaker in the bottom of described electromagnetism pin, comprise pedestal 18, adhesive pin rod 16, movable contact spot film 20, prop up spring 15, movable contact 13, stationary contact 14, adhesive pin rod 16 and the coaxial center hole that links to each other and pass pedestal 18 in the bottom of adhesive pin 10, pedestal 18 links to each other with the bottom of electromagnetism pin.Connect the tail end of movable contact spot film 20 on one side at its back side, another side has stationary contact 14, and it is springs 15 facing to the movable contact 13 of movable contact spot film 20 head ends at the middle part, the back side of movable contact spot film 20, and the end of adhesive pin rod 16 is facing to the middle part of movable contact spot film 20.
Described electromagnetism pin comprises electromagnetic coil 9, spring 11, adhesive pin 10, spring pedestal 12, adhesive pin 10, spring 11, spring pedestal 12 place the center hole of electromagnetic coil 9 successively, and the adhesive pin rod 16 that is connected with the bottom of adhesive pin 10 passes the spiral hole of spring 11 and the center hole of spring pedestal 12.
One insulating boot 17 is arranged outside described power breaker; One limiting stopper 23 is arranged at the back side of described movable contact.
Working procedure of the present utility model is; When the combustion gas in the environment reaches finite concentration, controller powers up for electromagnetic coil of the present utility model, adhesive pin 10 moves right under the effect of electromagnetic field, thin neck 21 is extracted out in the draw-in groove 8 of valve rod 5, valve rod 5 is pressed on the passway of valve body 1 at downward valve pad 2 with valve rod 5 ends under the effect of spring 6, makes closedown of pipeline.Meanwhile, adhesive pin rod 16 backs down movable contact spot film 20 to the right, and movable contact 13 and stationary contact 14 are disconnected, because this contact is serially connected with in the loop of electromagnetic coil 9, has both made controller be in state of alarm, and electromagnetic coil can not be powered yet.
Because valve rod 5 heads on the narrow neck end 21 of adhesive pin,, only pull out valve rod 5 and make thin neck 21 snap in draw-in groove 8 interior Open valves again by the people so under the situation of electromagnetic coil 9 outages, adhesive pin 10 is resetted.
