Description

Известны трубчатые пружины к манометрическим приборам, состо щие КЗ двух полосообразных деталей, соединенных по кра м.Tubular springs for manometric instruments are known, consisting of short-circuit parts of two strip-like parts connected along edges.

Недортатком подобного типа трубчатых пружин  вл етс  их температурна  деформаци , завис ща  от температуры окружающего воздуха, котора  искажает характеристику пружины и этим увеличивает погрешность измерени , выполн емого манометрическим прибором.A disadvantage of this type of tubular springs is their temperature deformation, depending on the temperature of the surrounding air, which distorts the characteristics of the spring and thereby increases the measurement error performed by the pressure gauge.

Отличительна  особенность предлагаемой трубчатой состоит в том, что, с целью компенсации температурных погренлностей, детали ее выполнены из материалов, имеющих различный коэффициент линейного расширени .A distinctive feature of the proposed tubular is that, in order to compensate for temperature fringes, its parts are made of materials with different linear expansion coefficients.

На фиг. 1 изображена трубчата  пружина, изогнута  по дуге окружности , общий вид; на фиг. 2 - поперечный разрез трубчатой пружины по АА.FIG. 1 shows a tubular spring bent in an arc of a circle, general view; in fig. 2 is a cross section of a tubular spring according to AA.

Трубчата  пружина состоит из двух полосообразных деталей 1 и 2, соединенных по кра м посредством сварки или каким-либо другим способом . Детали пружины выполнены из материалов, имеющих различный температурный коэффициент линейного расширени .A tubular spring consists of two strip-like parts 1 and 2, connected along the edges by welding or by some other method. The spring parts are made of materials having different temperature coefficient of linear expansion.

При правильном выборе материалов дл  деталей 1 и 2 перемещени  конца пружины, св занной с указателем манометрического прибора, которые обычно возникают от изменени  температуры окружающего воздуха или самого прибора, могут быть значительно уменьшенЕ или полкостью скомпенсированы.With the right choice of materials for parts 1 and 2, movements of the end of the spring associated with the gauge indicator, which usually arise from changes in ambient temperature or the device itself, can be significantly reduced or fully compensated.
