Abstract

1. Шариковый преобразователь расхода, содержащий корпус с входным угловым и выходным патрубками и крышкой, размещенной на торце корпуса, расположенное между патрубков сужающее устройство, установленную в полости корпуса около крышки кольцевую камеру с дорожкой качения, шаром, каналами завихрителя потока и коаксиальным стержнем-вытеснителем, образующим с кольцевой камерой полость, соединенную с полостью корпуса за сужающим устройством посредством присоединенной к ним трубы, а также узел съема сигнала, отличающийся тем, что в центре дорожки качения выполнен радиальный паз, к которому подключены выходы каналов завихрителя потока, образованных венцом радиальных лопаток, между полостью кольцевой камеры и полостью трубы размещено дополнительное сужающее устройство в виде перегородки с отверстиями, оси которых расположены в плоскостях, проходящих через ось стержня-вытеснителя, но не совпадают с ней, между входным патрубком и кольцевой камерой установлена перфорированная перегородка, а узел съема сигнала размещен на крышке. ! 2. Шариковый преобразователь расхода по п.1, отличающийся тем, что стенки кольцевой камеры образованы крышкой и венцом радиальных лопаток. ! 3. Шариковый преобразователь расхода по п.1, отличающийся тем, что кольцевой камерой, завихрителем потока, стержнем-вытеснителем, шаром и дополнительным сужающим устройством образован единый сменный узел. ! 4. Шариковый преобразователь расхода по п.3, отличающийся тем, что входы отверстий дополнительного сужающего устройства размещены около обоих торцов стержня-вытеснителя, который снабжен внутренней полостью, открытой в полость трубы, а дальние от т�1. A ball flow transducer containing a housing with inlet angular and outlet nozzles and a cover located at the end of the housing, a restricting device located between the nozzles, an annular chamber installed in the body cavity near the cover with a raceway, a ball, flow swirler channels and a coaxial displacement rod forming a cavity with the annular chamber, connected to the cavity of the body behind the restriction device by means of a pipe connected to them, as well as a signal pickup unit, characterized in that a radial groove is made in the center of the raceway, to which the outlets of the flow swirler channels formed by the crown of radial blades are connected , between the cavity of the annular chamber and the cavity of the pipe, there is an additional constriction device in the form of a partition with holes, the axes of which are located in planes passing through the axis of the displacement rod, but do not coincide with it, a perforated partition is installed between the inlet pipe and the annular chamber, and The signal meter is located on the cover. ! 2. A ball flow transducer according to claim 1, characterized in that the walls of the annular chamber are formed by a cover and a crown of radial blades. ! 3. A ball flow transducer according to claim 1, characterized in that a single replaceable unit is formed by the annular chamber, the flow swirler, the displacement rod, the ball and the additional restriction device. ! 4. A ball flow transducer according to claim 3, characterized in that the openings of the additional orifice device are located near both ends of the displacement rod, which is provided with an internal cavity, open into the pipe cavity, and distant from
