Adopt the technical program, oil-water interface control of the present invention mechanism combines automatic control system with pneumoelectric and compares, and has simple in structurely, easy to operate, is convenient to keep in repair, and construction amount is little, and operating cost is low.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The structural representation that Fig. 1 is oil-water interface control of the present invention mechanism.
Embodiment
As shown in Figure 1, the gas phase of the gas phase interface a of mechanical type oil-water interface control mechanism and three-phase separator is connected, the bottom aqueous phase of water interface c and three-phase separator is connected.The position level of answering of oil phase interface b is connected on the following place of exhaust port of three-phase separator oil.The oil-water interfaces height that ball float 1 spheroid 1/4 place in interface wants level to preset corresponding to three-phase separator, 1/4th of ball float in water, ball float 3/4ths in oil.Valve import d is connected with the discharging valve of three-phase separator.By the inlet tube UNICOM of valve outlet port e and decontaminated water processing station, in the middle of conduit, a switch valve to be installed.Pressure relief opening f is accessed to little drain tank.
After completing above-mentioned installation, should first open the valve of gas phase interface a, the valve of the interfaces c that fetches boiling water again successively, open the valve of oil phase interface b, opens valve import d, opens the switch valve in the middle of conduit.At this moment this mechanism has just started the oil-water interfaces in the auto-adjustment control three-phase separator.
The groundwork principle of this mechanism is that the oil-water interfaces signal that signal picked-up mechanism will absorb changes a hydraulic signal into, pass to actuator by conduit 21, this hydraulic signal amplifies in actuator, export a thrust, the promotion discharging valve is opened, the size of open degree, because the size of oil-water interfaces signal changes, thereby realize the automatic control to oil-water interfaces in three-phase separator.The power that he needs is from the pressure energy of native system self, without any need for the support of external force.
When in fluid level tube 2, the oil-water interfaces of (and in three-phase separator) fluctuate in a certain position, interface ball float 1 will drive needle type valve core 5 and move up and down the aperture of opening or turn down below, current just enter back pressure chamber 19 through conduit 21, when the water yield that flows into back pressure chamber 19 is greater than the discharge capacity of pressure relief opening f, the pressure of back pressure chamber 19 can slowly raise, and finally will promote piston and move upward, and move upward through push rod 11 promotion spools 8, thereby lower channel on discharging valve is opened, started draining.
When oil-water interfaces descend, interface ball float 1 falls after rise downwards, thereby needle type valve core 5 turns down the pressure drop that the below aperture makes back pressure chamber 19, and piston just pushes away under the multiple power effect of spring 14, thereby turns down or close discharging valve.
