Abstract
An intelligent pressure adjusting device for a surge tank is characterized in that a hole is formed in the middle of the tank wall of a round pressure surge tank; a pressure sensor provided with a display screen is fixedly mounted in the hole in the middle of the tank wall; flanges are arranged at two ends of a pressure regulator; the pressure regulator provided with the flanges is fixedly mounted on a flange at the upper end on one side of the surge tank; a flange of a pressure release valve is fixedly mounted at the upper end of the other side of the tank wall of the surge tank through bolts; the pressure release valve provided with the flange is fixedly mounted on the surge tank through bolts; an air delivery pipe and the pressure regulator are connected through bolts; a PLC controller is connected with the pressure sensor and the pressure release valve through lead wires respectively, and is coupled with an EM235 digital-to-analog conversion module; and the EM235 is embedded into the PLC controller. The pressure adjusting device guarantees the pressure stability of a gas system through monitoring and adjusting the gas pressure in the surge tank.
Description
Technical field
The utility model relates to a kind of pressure buffer device, says a kind of knock out drum pressure intelligent adjusting device specifically.
Background technique
Knock out drum is widely used in central air-conditioner, boiler, water heater, frequency conversion, the constant pressure water supply equipment; it mainly is the fluctuation of resolve buffer system pressure; eliminate water hammer effect; play the voltage stabilizing off-load; guarantee the stable effect of system pressure; knock out drum also has anti-suck (vacuum system) in chemical industry, the effect of vapor-liquid separation, protection equipment and pressure instrument stable operation.But all there are the inaccurate and slow shortcoming of speed of response of pressure control in common diaphragm formula knock out drum and air sac type knock out drum.
Summary of the invention
The purpose of this utility model is to have the inaccurate and slow shortcoming of speed of response of pressure control at the ordinary buffer jar, and a kind of knock out drum pressure intelligent adjusting device is provided.
The utility model technological scheme that is adopted of dealing with problems is: knock out drum pressure intelligent adjusting device is to be made of pressure transducer, EM D/A converter module, PLC controller, pressure regulator, pressure surge tank, pneumatic tube, Decompression valves, it is characterized in that: in the middle of pressure surge tank, be provided with the hole on the tank skin, will be with the pressure transducer of display screen to be fixed in the hole; The two ends of pressure regulator is provided with flanged (FLGD) tube head, and the pressure regulator that will be provided with flange with bolt is fixed on the flange of knock out drum one side; Be provided with tube head in knock out drum opposite side tank skin upper end, tube head is welded with flange, and flange on the Decompression valves and tube head upper flange install and fix together; Pneumatic tube is connected by bolt with pressure regulator; The PLC controller connects with datawire with the EM235 module, with lead the EM235 module is connected with pressure transducer, pressure regulator.
The beneficial effects of the utility model are: by knock out drum pressure intelligent adjusting device is monitored in real time and regulated gas pressure in the tank body, the quick response of realization usefulness gas system pressure and stable guarantees usefulness gas system pressure stability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples

Embodiment
In the embodiment of Fig. 1 and Fig. 2, on the middle tank skin of pressure surge tank 7, be provided with the hole, the pressure transducer 6 of being with display screen is fixed in the middle hole of tank skin; The two ends of pressure regulator 6 is provided with pipe, and an end of pipe is provided with flange, will be provided with the pressure regulator 6 of flange, is fixed on the knock out drum 7 tank skins one side upper flanges with bolt; Be provided with flange in knock out drum 7 opposite side tank skins upper end, the Decompression valves 8 that has flange be fixed on the knock out drum 7 opposite side tank skin upper flanges with bolt; With bolt pneumatic tube 9 is installed on the pressure regulator 6, pneumatic tube 10 is installed on the pneumatic tube 9.PLC controller 3 connects with EM235 module 4 usefulness datawires; Pressure transducer 1 is connected with EM235 module 4 by lead 2, and pressure regulator 6 connects by the EM235 module 4 of lead 5.
Working principle of the present utility model: at first according to producing the gas consumption needs, set knock out drum inner control pressure by the PLC controller, pressure transducer is monitored a jar interior gas pressure in real time, and electric pressure signal flowed to the EM235 module by lead, convert the electrical signal to data-signal by the EM235 module and flow to the PLC controller, when the knock out drum internal pressure is lower than pilot pressure, the PLC controller sends control signal, convert data-signal to electrical signal by the EM235 module, the pilot pressure regulator, pressure regulator is opened valve, gas enters knock out drum, and gas pressure increases in jar, when returning to setup pressure value, PLC controller pilot pressure regulator valve is closed, and realizes pressure transient equiliblium.
