Abstract

The invention relates to an integral high-pressure small-flow regulator which comprises a shell, a pressure difference regulation component, a power regulation component, a slide valve seat and a supporting sleeve, wherein the supporting sleeve is arranged at the inlet of the shell; the supporting sleeve comprises an inlet diversion sleeve and a spacing seat which are sequentially and fixedly connected; the inlet diversion sleeve is provided with an inlet throttling hole; the slide valve seat comprises a fixed barrel and an outlet diversion sleeve which are sequentially and fixedly connected; the other end of the fixed barrel is fixedly connected with the support sleeve; the other end of the outlet diversion sleeve is fixed on the shell; and the outlet diversion sleeve is provided with an outlet throttling hole. The integral high-pressure small-flow adjuster is used for solving the technical problems of low precision and poor stability of an existing medium flow regulating system, can be used for controlling the flow of a liquid medium in a liquid control system, and is stable in flow and high in precision under the operating conditions of high pressure and great pressure changes.

Description

technical field [0001] The invention relates to a flow regulator structure for controlling flow stability, especially for liquid control systems in modern aviation, aerospace, petrochemical and other fields, and is used for accurately adjusting and stabilizing the flow of medium in the liquid control system. Background technique [0002] In modern aviation, aerospace, petrochemical and other liquid control systems, the inlet and outlet pressures usually change, which requires the adjustment of the medium flow to stabilize the outlet and inlet pressures. However, the adjustment accuracy of the current medium flow adjustment device is relatively low, and it is not stable enough when the pressure changes greatly, so it cannot meet the requirements of the working accuracy of the liquid control system. [0003] At the same time, it is necessary to precisely adjust the flow rate of the medium to meet the accuracy of the liquid control system and the effectiveness of the adjustment...
