Abstract
The utility model relates to a voltage- regulation device, in particular to a pipe steam voltage regulation device, consisting of a steam opening valve 1, a controller 3 and a pressure sensor 2. The steam opening valve 1 is arranged on a steam pipe 4; the pressure sensor 2 is arranged on the steam pipe 4 which is in the steam outlet direction of the steam opening valve 1; an output end of the controller 3 is connected with an executive parts of the steam opening valve and an input end is connected with the output end of the pressure sensor 2. The utility model can be applied to various facilities which take the steam as a thermal source, and integrates the controller, the pressure sensor and the steam opening valve into a closed circle control system to be applied to the steam pressured voltage devices to realize the automatic voltage regulation of the system steam.
Description
The utility model relates to a kind of stable-pressure device, particularly pipeline steam stable-pressure device.
The purposes of saturated vapor or superheated steam is a lot, wherein, with it is that to supply with various drying plants are a kind of in these all multipurposes to thermal source, no matter what purposes saturated vapor or superheated steam make, its pressure stability of universal demand, as when being used as the thermal source of drying plant, system is converted to vapor (steam) temperature the temperature of other carrier, reach being carried out drying by the oven dry thing, in order to guarantee to be dried every outlet index (comprising temperature, moisture etc.) of thing, requirement temperature to drying plant in drying course is controlled.If the steam pressure instability will cause the change of various parameters, miss one's aim.In actual use, the fluctuation of steam pressure is a kind of general phenomenon, and fluctuation how to eliminate system's steam pressure is one of problem that requires study in the sector.
The purpose of this utility model aims to provide a kind of system's steam pressure of eliminating and fluctuates, can make system's steam pressure to be controlled at the interior steam pressure stable-pressure device of setting pressure scope.
Steam pressure stable-pressure device described in the utility model, constitute by steam aperture valve, controller and pressure sensor, steam aperture valve is arranged on the jet chimney, pressure sensor is arranged on the jet chimney with respect to steam aperture valve steam (vapor) outlet direction, the output of controller is connected with the executive component of steam aperture valve, and input is connected with the output of pressure sensor.
Steam pressure stable-pressure device described in the utility model, can be applied to various is in the equipment of thermal source with steam.It applies to controller, pressure sensor and steam aperture valve composition closed-loop control system in the stable-pressure device of steam pressure, realizes the automatic voltage regulation effect to system's steam, reduces the influence that the steam pressure fluctuation causes equipment, improves the control index of equipment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a principle schematic of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
Among the figure: 1-steam aperture valve, 2-pressure sensor, 3-controller, 4-jet chimney, K-steam pressure setting value.
Accompanying drawing can be as embodiment of the present utility model.
The utility model is by steam aperture valve 1 among the figure, pressure sensor 2, controller 3 is formed, steam aperture valve 1, pressure sensor 2 all is located on the jet chimney 4, and steam aperture valve 1, pressure sensor 2, controller 3 is formed closed-loop control system, system's steam enters drying plant through steam aperture valve, the frequent detection system steam pressure of pressure sensor is set behind steam aperture valve, deliver in the controller and compare with setting pressure, enter the steam pressure of drying plant by the aperture adjustment of controller control aperture valve, reach the effect of steam voltage stabilizing, improve the temperature control index of drying plant.Wherein used steam aperture valve 1 can be air bladder valve, motor-driven valve, ecp membrane valve or electronic angle actuator.
The setting value K of described steam pressure is less than or equal to system's steam pressure value.
