The invention can be installed in a rectangular pipeline for regulation of flow, the flow coefficient is high, and has the characteristics of low pressure differential at largest flow.
Description
Technical field
The invention belongs to flow regulator, be specifically related to a kind of flow regulator that can be applicable to rectangular duct.
Background technique
Flow regulator generally adopts modulating valve, and modulating valve is equivalent to an adjustable local resistance element, changes orifice size by moving of spool.An important parameter of modulating valve is the circulation coefficient, it is defined as: when the modulating valve standard-sized sheet, the pressure reduction at valve two ends is 100Kpa, when fluid severe is 1gf/cm3, per hour the flow through flow number of modulating valve, the size of hence one can see that circulation coefficient has been reacted the negotiability of this modulating valve.The circulation coefficient maximum of with regard to existing various modulating valve, having only ball valve and butterfly valve.
Carrying out CNP1000 reactor coaming plate bleeder when test stream, several flow regulators need be installed in a rectangular duct, requirement particular flow rate lower device two ends pressure reduction when standard-sized sheet is very little, needs this flow regulator flow characteristics coefficient that greatly promptly circulates big.The ball valve of coefficient maximum or butterfly valve are installed the big flow characteristics that also can't meet the demands even will circulate, the passage that adds this type of valve is for circular, if use this type of valve, its circulating face carries out the transition to circle from rectangle and transits back rectangle more again, negotiability is reduced greatly, and installation dimension does not allow yet.
Summary of the invention
The object of the present invention is to provide a kind of can being installed in the rectangular duct, and the big flow regulator of circulation coefficient.
Realize the technological scheme of the object of the invention: a kind of flow regulator, it comprises Flow-rate adjustment orifice plate and controlling mechanism, wherein, said Flow-rate adjustment orifice plate is a rectangular double-layer Flow-rate adjustment orifice plate, and it is by having the hole, and perforate size, perforate quantity and the identical fixation plate of position of opening and sliding steel plate are formed, the inclined-plane projection has been done at the fixation plate two ends, the corresponding both ends of the surface of sliding steel plate are the inclined-plane, just in time are installed on the fixation plate, and two steel plates can be slided along specific direction; Said controlling mechanism is a threaded adjusting mechanism, it comprises regulating handle, adjusting nut, screw rod, adjustment seat and fixed block, adjustment seat is installed on the rectangular duct, be provided with screw rod in the adjustment seat, its lower end is connected with sliding steel plate, the other end is threaded with adjusting nut, adjusting nut is provided with regulating handle, regulating handle, adjusting nut and screw combinations can make the sliding steel plate of double-deck orifice plate move in the axial direction, fixed block is fixed on adjusting nut on the adjustment seat in the axial direction, and adjusting nut only can be rotated vertically.
Effect of the present invention: rectangular double-layer Flow-rate adjustment orifice plate can be installed in the rectangular duct, slide by the dislocation between two orifice plates of rectangular double-layer Flow-rate adjustment orifice plate and to change the circulation area of passage, to change flow, thereby can realize the Flow-rate adjustment in the rectangular duct, and pressure reduction little characteristics in two ends when having peak rate of flow; The big I of rectangular double-layer Flow-rate adjustment orifice plate perforate is determined by the adjusting flow that requires; The circulation coefficient of comparing this device with identical inside nominal diameter flow regulator is big.
