Background technique
Self-operated flow regulator generally comprises valve body, valve seat, spool, valve rod, valve gap, Regulation spring, controlling diaphragm chamber, the controlling diaphragm chamber is isolated into upper film chamber and following film chamber by diaphragm, upper film chamber introduces downstream pressure by control valve, upstream pressure is introduced by control valve in following film chamber, is provided with Regulation spring in the upper film chamber.The balance of the pressure differential deltap P of the difference of upstream pressure and downstream pressure and Regulation spring elastic force, the position of decision spool and the flow by valve seat.Variation control media flow by pressure differential deltap P does not need external power source, reaches the current stabilization of flow is regulated.Self force type temperature regulating valve comprises modulating valve and final controlling element, modulating valve comprises valve body, valve seat, spool, valve rod, valve gap, and final controlling element comprises regulator and temperature transducer, and temperature transducer is the hydraulic pressure thermometer bulb, be installed in the controlled medium channel, be communicated with the oil hydraulic cylinder of regulator by conduit.When the temperature of controlled medium descended, the liquid contraction in the temperature transducer hydraulic pressure thermometer bulb descended the hydraulic pressure in the oil hydraulic cylinder, the final controlling element push rod drives valve rod, spool moves down, valve opening increases, and by the high-temp liquid increase of valve, controlled medium temperature is gone up.Otherwise when the temperature of controlled medium rose, the regulating and controlling by final controlling element fell the temperature of controlled medium after rise, does not need external power source, realizes the thermostatically control to controlled medium.But self-operated flow regulator and self force type temperature regulating valve can only be realized respectively flow and temperature controlling, can not be simultaneously to flow and two parameter control of temperature.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides a kind of and can be simultaneously flow and temperature be regulated self-powering type flow-temperature combination modulating valve of control.
The technical solution of the utility model comprises modulating valve, flow dontroller and temperature controller, modulating valve comprises valve body, valve seat, spool, valve rod, valve gap, flow dontroller comprises diaphragm, diaphragm case, Regulation spring, adjustable lever, temperature controller comprises regulator and temperature transducer, mainly be that the flow dontroller adjustable lever is connected with valve rod by assembly parts with the temperature controller adjustable lever, this assembly parts comprises a housing, the distant bar of push rod and triangle, the push rod upper end is connected with valve rod, the adjustable lever of push rod lower end and flow dontroller contacts, the push rod middle part is provided with a boss, a drift angle of the distant bar of triangle is installed in the housing by rest pin, two adjacent drift angles contact with boss following table and temperature controller adjustable lever respectively, and the distant bar of triangle can rotate on the rest pin.
In above technological scheme, the flow dontroller adjustable lever is concentric with push rod, meets at right angles with the temperature controller adjustable lever.
The utility model beneficial effect compared with prior art is that flow dontroller is connected with modulating valve by an assembly parts with temperature controller, relies on the flow and the temperature of self medium, realizes simultaneously flow and temperature being carried out regulating and controlling.
