Abstract
The invention relates to a valve, in particular to a valve for regulating flow of high pressure compressed air. The valve comprises a balanced valve clack combined piece, a valve cage and a valve cap component, wherein the valve cap component is placed at the upper end of the valve body; the valve cage is placed in the valve body; the balanced valve clack combined piece is placed in the valve cage and extends out of the valve cap component; and a window of the valve cage is a V-shaped window. In the high pressure compressed air regulating valve provided by the invention, through the adoption of a group of regular circular holes in a fixed flow limiting pore plate, the pressure of the compressed air can be effectively attenuated and a rectifying effect can be obtained; and on the basis of the effect of the fixed flow limiting pore plate, a replaceable flow limiting pore plate can be replaced according to the actual need of a pressure regulating range and according to a value indicated on a pressure gauge in a pressure port. The invariability of flow characteristic of a common regulating valve is overcome.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of valve of Flow-rate adjustment of high pressure air.
Background technique
Aircraft wind-tunnel test site and with the place of pressurized air as power source, need to do accurate the adjustment to the flow of high pressure air, changes in flow rate is frequent, the scope of pressure, changes in flow rate is large, and the zero leakage under requiring in off position.For overcoming the formed collapsing force of this special operation condition, noise, electric shock, leakage, satisfy the ability of the linearly adjust flow under this operating mode, develop this kind product.
Summary of the invention
The present invention is directed to and diminish the power of destruction, noise, electric shock and leakage problem provide a kind of high pressure air modulating valve.
The present invention adopts following technological scheme:
A kind of high pressure air modulating valve of the present invention, comprise valve body, balanced type flap assembly parts, valve cage, bonnet assemblies, described valve body upper end arrangement of valves cap assemblies is arranged valve cage in the valve body, balanced type flap assembly parts is arranged in valve cage and extends bonnet assemblies, and the window of described valve cage is the V-shape window mouth.
Beneficial effect
High pressure air regulating valve provided by the invention has overcome the ability that linearly adjust flow under the operating mode is satisfied in the formed collapsing force of special operation condition, noise, electric shock, leakage.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is V-shape window mouth valve cage structure schematic representation of the present invention;
Fig. 3 is V-shape window mouth structure schematic representation of the present invention;
1 is valve body among the figure, the 2nd, and balanced type flap assembly parts, the 3rd, valve cage, the 4th, bonnet assemblies, the 5th, pressure tappings.
Embodiment
The present invention is described in more detail below in conjunction with accompanying drawing:
As shown in the figure: a kind of high pressure air modulating valve comprises valve body 1, balanced type flap assembly parts 2, valve cage 3, bonnet assemblies 4.
Valve body 1 upper end arrangement of valves cap assemblies 4, valve body 1 interior layout valve cage 3, balanced type flap assembly parts 2 is arranged in valve cage 3 and extends bonnet assemblies 4, and the window of described valve cage 3 is the V-shape window mouth.
Balanced type flap assembly parts 2 relies on the interference fit of upper-lower seal rings (macromolecular material) and V-type window type valve cage 3 can guarantee that All Media all regulates laggard inlet/outlet by the window of V-type, and the up and down conical surface seal face (Hardmetal materials) of flap guarantees zero leakage with conical surface seal face (Hardmetal materials) in the valve cage under the valve full closing state.This structure that forms a complete set of can guarantee the long service life of zero leakage under the accurate adjustment, closed condition of the flow of valve, sealing surface.
Space in the middle of valve body 1 and the V-type window type valve cage 3 is enough impacted and destruction and the acoustic shock of generation valve cage and valve body with the pressurized air that overcomes after regulating greatly.
