More Information
Summary:The utility model relates to a digital display flow pressure difference valve, comprising a valve body, a valve cover, a spool, a spring, a spring cylinder, a sensor pressure film plate, a flow core, a sensor, a displayer or the like, wherein the sensor pressure film plate separates the valve body into an film upper portion and a film lower portion, the film upper portion is connected with the spool, the lower portion is equipped with the spring, the pressure difference between the film upper portion and the film lower portion is fixed by the effective area of the film plate, when the pressure difference between the film upper portion and the film lower portion is above or below the setting pressure difference value, the film plate will drive the spool bigger or close the valve smaller to stabilize and control the pressure difference, thereby constant the pressure difference, a cross pressure adjusting valve on the valve cover is used to adjust, set and control the pressure difference, the water inlet side of the pressure difference is equipped with a flow machine core, the sensor and the monitor on the flow machine core and the valve body are a whole set of flow display device to display the flow quantity which flows the valve when the controlled pressure difference varies for correct setting, adjusting the pressure difference and the flowing quantity, which provides important digital evidence for the adjustment of the system and is a new typed pressure difference controlling valve.
