Description
Technical field
The utility model relates generally to fluid conditioner, more specifically, relates to the axial flow fluid conditioner with equilibrium valve internals assembly.
Background technique
Regulator usually is used in fluid or the gas distributing system, in order to the pressure in the down-stream system that is controlled at regulator.As everyone knows, the pressure of supply gas can change according to requirement, weather, supply source and/or other factors to system in common gas distributing system.Yet great majority have for example been equipped, and need gas be carried according to predetermined pressure intensity parameter such as terminal use's facility of gas device such as boiler, baking oven.Therefore, those distribution systems use regulator, and the gas of carrying in order to guarantee satisfies the demand of terminal use's facility.
In fluid or gas conditioner (general name " fluid conditioner "), the Consideration of many designs and performance can be important.For example, the artificer of fluid conditioner possibly make great efforts to design and have higher pressure stability and the regulator for the receptance of inlet pressure change that reduces.In addition, the artificer possibly make great efforts to construct smaller and more exquisite design proposal, and designs and be easy to the regulator of assembling and serving.
Known polytype fluid conditioner, for example, sliding stem regulator, rotary actuator etc.In some regulators, such as, sliding stem regulator and rotation valve acutator are when fluid passes through valve seat, through mobile 90 degree or more that reversed of the fluid of valve.90 degree to reverse be essential be oriented substantially perpendicular to fluid flow direction because be used for the valve acutator of valve, and valve plug is oriented move (that is, perpendicular to fluid flow direction) that is parallel to valve acutator, in order to simplify valve acutator-valve plug interface.Yet in some applications, owing to reverse the fluid flow path through regulator, some sliding bars and rotary actuator possibly vibrated and lost valve efficient.
In-line valve or tubular type flow control valve can substitute sliding stem and rotary control valve.The axial flow valve has flow path or the passage that runs through valve, and it is perpendicular or parallel in fact in fluid flow direction, is used to minimize the turbulent flow through valve body.The axial flow control valve generally includes valve acutator, and it is mounted to the outer surface of valve body.Valve acutator operationally is coupled to the FLOW CONTROL member of valve and between open position and closed position, is moved the FLOW CONTROL member, in order to allow or to stop fluid to pass through flowing of valve.Some known axial flow control valves activate the control member that flows with respect to seat ring in valve body, in order to control fluid flowing through valve body.
Yet the axial flow regulator usually is unbalanced.Inlet receptance, valve plug that unbalanced configuration causes increasing vibrate and the low discharge coefficient, especially under higher pressure situation.Therefore, in operation with high pressure, usually do not use high-pressure shaft to flow conditioner.
