Description
Известны индикаторные устройства к магнитному дефектоскопу, выполненные в виде магнитного моста, двум смежными плечами которого служат два смежных учасгка провер емого ферромагнитного издели .Indicator devices to a magnetic flaw detector are known, made in the form of a magnetic bridge, the two adjacent arms of which are two adjacent parts of the tested ferromagnetic product.
Недостатком этих устройств вл етс их низка чувствительность при контроле качества сварных швов.The disadvantage of these devices is their low sensitivity when monitoring the quality of welds.
Предложенное устройство не имеет указанного недостатка.The proposed device does not have the indicated disadvantage.
Сущность изобретени заключаетс в том, что магнитный мост устройства выполнен в виде двух магнитных сердечников. Один из сердечников имеет П-образную форму и своими двум концами магнитно замыкает между собой середины стержней первого сердечника . При этом его третий конец совместно с концами первого сердечника образует три полюса моста, которые служат дл установки на поверхности издели .The essence of the invention is that the magnetic bridge of the device is made in the form of two magnetic cores. One of the cores is U-shaped and with its two ends it magnetically interconnects the middle of the cores of the first core. At the same time, its third end, together with the ends of the first core, forms three poles of the bridge, which are used for mounting on the surface of the product.
На чертеже схематически изображено предложенное устройство.The drawing schematically shows the proposed device.
Основным элементом устройства вл етс магнитный мост, который составлен из двух магнитных сердечников. Первый сердечник / имеет П-образную форму и снабжен в средней части на.магничивающей обмоткой 2. Второй сердечник 5 имеет Т-образную форму. Его два конца магнитно замыкают между собой середины стержней первого сердечника, а его третий конец, располагаемый между двум концами первого сердечника, устанавливаетс совместно с ними на поверхности провер емого издели 4. Этот третий конец снабжен измерительной обмоткой 5.The main element of the device is a magnetic bridge, which is composed of two magnetic cores. The first core / is U-shaped and is provided in the middle part with a magnetising winding 2. The second core 5 is T-shaped. Its two ends are magnetically interlocked between the middle of the cores of the first core, and its third end, located between the two ends of the first core, is installed together with them on the surface of the tested product 4. This third end is provided with a measuring winding 5.
Магнитный поток дл питани моста создает сердечник 1, обмотка 2 которого питаетс переменным током промышленной частоты. В плечо АД входит в качестве составл ющей магнитное сопротивлениеThe magnetic flux for powering the bridge creates a core 1, the winding 2 of which is powered by industrial frequency alternating current. Blood pressure is included in the arm as a component of magnetic resistance.
