Abstract
The utility model provides a dual magnetic controlling valve, comprising an air cavity which comprises an air inlet and an air outlet, an armature which is arranged in the air cavity and open and close the air inlet and the air outlet, a coil arranged on the air cavity and a permanent magnet. The utility model can be sucked to move and stop and be locked by the armature, the coil and the permanent magnet, and the utility model needs only to add instant electricity but needs not to keep electricity adding for long time. So the utility model can close the air supply in time and can not be affected by power failure and power cutting off after starting, and the utility model is suitable for being used in a flammable gas leakage protection system.
Description
The utility model relates to a kind of control valve, particularly be two magnetic control system valves that a kind of gas, liquid cut-off.
The pressure-limit valve that existing coal gas, liquefied gas stove use only has functions such as pressure limiting, non-return fire.When liquid gas takes place to leak, can not in time close source of the gas automatically, easily cause fire.Therefore people have further invented security personnel's pressure-limit valve that can automatically shut down source of the gas again.But existing security personnel's pressure-limit valve cuts out the power of source of the gas, lean on electromagnet to switch on continuously and keep, and therefore, in case run into when having a power failure, this function just can not guarantee.
In view of above reason, the purpose of this utility model is can in time close source of the gas automatically in order to provide a kind of, is not stopped the influence of cutting off the power supply after the startup, is specially adapted to the two magnetic control system valves in the inflammable gas leakage protection system.
The air cavity that contains suction port, air outlet is arranged in the utility model control valve, place air cavity and armature that can open, break air inlet/outlet, be loaded on the coil on the air cavity, permanent magnet (referring to Fig. 1).
Permanent magnet is housed on the above-mentioned permanent magnet revolves axle (referring to Fig. 1).
The first half that is positioned at armature in the above-mentioned air cavity has the hermetically sealed air cavity cover (referring to Fig. 1) that is connected with air cavity, makes the utility model top totally-enclosed.
Spring (referring to Fig. 1) is arranged on the above-mentioned armature, armature is resetted rapidly.
O RunddichtringO (referring to Fig. 1) is equipped with at the air inlet/outlet place of above-mentioned air cavity respectively.
Referring to Fig. 1, when coil power up produce magnetic field after, rapidly armature is drawn onto the top and is firmly held by permanent magnet, at this moment coil can stop to power up, and armature is sucked locking by permanent magnet and can not reset.When the turn permanent magnet, make armature throw off permanent-magnetic field, valve can reset.Can be made into open in usual or Normally closed type gas, Liquid valve with this control principle the utility model.
The utility model is inhaled moving by armature, coil, permanent magnet holds locking, can improve the life-span of electromagnetic coil and the power consumption of minimizing electromagnetic coil greatly at the power supply of second internal cutting off electromagnetic coil.Only need moment to power up, and do not need to power up for a long time maintenance, so can in time close source of the gas, the influence of the outage that do not had a power failure after the startup is specially adapted to the inflammable gas leakage protection system.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, establish suction port 2, air outlet 3 on the air cavity 1, valve gap 4 is loaded on air cavity 1 bottom by screw, and coil housing box 5 is loaded on air cavity top, and the coil 7 that is wrapped on the coil rack 6 is wherein arranged.Permanent magnet 8 places coil housing box 5 tops, has permanent magnet to revolve axle 9 on it.Armature 10 is loaded in the air cavity 11, and spring 12 is housed on it, and air cavity cover 13 is positioned at the first half of armature and is contained on the air cavity by screw.At air cavity and valve gap joint, air cavity air inlet/outlet place O RunddichtringO 14,15,16 is housed respectively.
Claims (5)
1, two magnetic control system valves is characterized in that the air cavity that contains suction port, air outlet is arranged in the described control valve, place air cavity and armature that can open, break air inlet/outlet, are loaded on the coil on the air cavity, permanent magnet.
