Abstract
The utility relates to a high pressure regulating valve, which comprises a valve body provided with a valve chamber; a valve rod is disposed in the valve chamber; the valve body is provided with a medium flow-in passage for a medium to flow into the valve chamber and a medium flow-out passage for the medium to flow out from the valve chamber, and the high pressure regulating valve further comprises a large valve core provided with an inner chamber and a small valve core arranged in the inner chamber and linked with the valve rod. The large valve core is provided with a connecting passage for connecting the inner chamber with the medium flow-out passage; the valve rod drives the small valve core to move up and down to realize connection or disconnection between the inner chamber and the medium flow-out passage; a sleeve valve cage is arranged outside the large valve core; a connecting passage connected with the medium flow-in passage is arranged on the sleeve valve cage; the large valve core is provided with a medium flow passage connected with the inner chamber, and the small valve core drives the large valve core to move up and down to realize connection or disconnection between the medium flow-in passage and the inner chamber. By use of the technical scheme, the utility model provides a high pressure regulating valve which is convenient for controlling opening or closing of the valve under condition of high pressure difference.
Description
Technical field
The utility model relates to the valve class, particularly a kind of septum valve.
Background technique
At present, existing a kind of modulating valve, include the valve body that is provided with valve pocket, the spool that is provided with valve rod in the valve pocket and fixedlys connected with valve rod, valve body is provided with for the medium flow channel of medium inflow valve pocket, for the medium flow pass of medium outflow valve pocket, and valve rod driving valve core movement is realized the unlatching of modulating valve or closed.
But the modulating valve of this structure flows out under the bigger condition of channel pressure difference at medium flow channel, medium, and spool pressure at both sides imbalance makes that the drive ratio of valve rod is difficult, and modulating valve is difficult to open or cut out.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of septum valve, under the High Pressure Difference condition, can make things convenient for the unlatching of regulating and controlling valve or closes.
The technical solution of the utility model: a kind of septum valve, comprise the valve body that is provided with valve pocket, be provided with valve rod in the valve pocket, valve body is provided with the medium flow channel that flows into valve pocket for medium, flow out the medium flow pass of valve pocket for medium, also include the big valve core that is provided with inner chamber, be arranged in the inner chamber and the small valve core valve rod interlock, described big valve core is provided with the pathway of conducting inner chamber and medium flow pass, valve rod drives small valve core and moves up and down and realize the conducting of inner chamber and medium flow pass or end, described big valve core is arranged with the telescoping valve cage outward, described sleeve valve cage is provided with the connecting passage with the conducting of medium flow channel, described big valve core is provided with the medium runner with the inner chamber conducting, and described small valve core drives big valve core and moves up and down and realize the conducting of medium flow channel and inner chamber or end.
Adopt technique scheme, medium is entered by the medium flow channel, the moment of opening, the force rate of valve rod driving small valve core is less, after opening small valve core, described big valve core inner chamber and the conducting of medium flow pass, after small valve core rises arrival inner chamber top, the drive big valve core moves upward, make described big valve core inner chamber and the conducting of medium flow channel, can control by the medium runner on the control big valve core and the flow cross section of the connecting passage on the sleeve valve cage and the adjusting that flow is realized in the flow cross section between small valve core and the pathway, during throttle down, when small valve core drops to intracavity bottom, drive big valve core and move downward, realize closing of valve.This structure Design makes under the High Pressure Difference condition, still can make things convenient for the unlatching of regulating and controlling valve or closes.
Further setting of the present utility model: be provided with pressure spring between described small valve core and the big valve core inner chamber.
Adopt above-mentioned further setting, set up pressure spring, can conveniently drive small valve core and move upward, make that the power that drives the small valve core motion is littler, convenient.
Further setting more of the present utility model: be provided with guide ring between described big valve core and the sleeve valve cage.
Adopt above-mentioned further setting again, guide ring is set makes things convenient for the motion of big valve core more smooth and easy.
