Description
Technical field
The utility model relates to valve field, specifically a kind of dual control conic valve.
Background technique
Valve is the important control gear of fluid circuit; its fundamental function merit is the circulation switching on or off pipeline medium, regulates the flow direction of medium, pressure and flow, the normal operation of protection pipeline and equipment; current water flowing valve mostly is ball valve, and accessory rapid wear is short for working life.
In actual applying working condition, when flowing medium flows to the throttling of spool from valve inlet, sectional area due to throttling place diminishes so flow velocity sharply increases, static energy is sharply converted into kinetic energy, pressure sharply declines, when pressure is reduced to vapor pressure, namely water can gasify, produce bubble, bubble is with after water flow to spool, flow velocity falling pressure recovers, when pressure recover is to when being greater than the saturation vapour pressure of medium, the steam of gasification reverts to liquid condition again, and the bubble produced when gasifying can break and discharges the noise that huge energy causes valve, the damage of vibration and valve part, be referred to as cavitation erosion, during existing valve regulated, because the profile variation at spool place is large, and profile is irregular, thus causes velocity variations to be easy to very greatly cavitate, and cavitation erosion can reduce the working life of valve greatly, adds maintenance cost.
