Abstract

The utility model relates to a float-level adjusting type steam-water separator, and particularly a steam-water separator used on heating pipes. The utility model is composed of a tank, a liquid level relay, a floating ball, and an electromagnetic valve. The swing link of the liquid level relay gets into the tank, and the other end is provided with the floating ball. The up and down floating of the floating ball controls the actions of the magnetic steel, the magnetic steel drives normally open contacts to work and control the actions of the electromagnetic valve to discharge the condensed water. The utility model has the advantages of large water displacement, reliable motion, high draining efficiency, energy saving, wide range of application, etc., and is free from temperature difference influence.

Description

Float-level adjusting type steam trap

The utility model relate to be used on the heat supplying pipeline steam-water separator, particularly a kind of ball float position formula of specializing on the paper machine dryer discharge pipe line is regulated steam-water separator.

At present, in heating system, generally all adopt STEAM TRAP to come condensed water in the discharge conduit, the kind of its STEAM TRAP had hot power, float-ball type, floating-tube type and column sleeve float type, this class STEAM TRAP is in that to be used for steam flow little, and is comparatively desirable on the little pipeline of temperature fluctuation.But in the time of on being used for the paper machine dryer discharge pipe line; because it is indefinite that the paper machine is shut down the time of maintenance or discharge fault in process of production; as overlong time; dryer temperature sharply descends; steam inside is condensed into water; the condensed water that has in the sub-cylinder in addition; after the start of paper machine; the drying cylinder internal pressure is lower, and it is very difficult in very short time condensed water being discharged, and the movable member of STEAM TRAP is soaked in the hot water in addition; column sleeve or float gap are less; the impurity that is condensed easily in the water stops up, and reduces drain function, even causes draining malfunctioning.

The purpose of this utility model is to provide a kind of water displacement big, and reliable in action is not subjected to temperature difference influence, and the ball float position formula of energy saving is regulated steam-water separator.

The purpose of this utility model is achieved in that it comprises the tank body that has suction tude and secondary steam outlet pipe, liquid level relay, ball float, solenoid valve, top or sidepiece at tank body are equipped with liquid level relay, the fork of liquid level relay feeds in the tank body, the other end is equipped with ball float, in the tank body bottom waste pipe is housed, solenoid valve is housed on the waste pipe, the utility model is at first determined the upper and lower position of ball float, liquid level relay is controlled its magnet steel action by control circuit, when ball float rises in limited time, its magnet steel motion drives a pair of normally opened contact closure, make the time relay, auxiliary reclay and red led get electric auxiliary reclay normally opened contact closure, make solenoid valve work, discharge condensed water.Prescribe a time limit when ball float falls to down, its magnet steel normally opened contact is opened, the time relay, auxiliary reclay, red led dead electricity, the auxiliary reclay normally opened contact is opened, and the solenoid valve dead electricity stops draining, this moment, the liquid level relay normally-closed contact was connected, and green indicating lamp gets.

In the utility model, for the opens solenoid valve draining phenomenon that prevents to transfinite not takes place, in control circuit, be provided with time relay circuit, in order to the control acoustic-optic alarm, and fix a breakdown by manual operating device.

The utility model has the advantages that: 1, the utility model is controlled water displacement by regulating the ball float upper and lower, thereby is not subjected to the restriction of water discharge time because steam enters behind the tank body condensation discharges; 2, the utility model is controlled ball float by liquid level relay, has solved existing STEAM TRAP and has relied on ball float to drive the problem of column sleeve, has improved drainage efficiency; 3, the utility model is controlled draining by relay, and reliable in action is not limited by the temperature difference, in a large number energy saving; 4, the utility model is because the steam-water separator tank body adopts 0.15～0.2 cubic metre volume of welded steel plate, and this volume is far longer than the volume of STEAM TRAP.Therefore it not only plays the retaining effect of alleviating mass flow discrepancy, and after steam water interface flows into steam-water separator, because the consumption internal pressure naturally and the temperature of energy all will reduce, thereby the pressure reduction of drying cylinder and steam-water separator, the easier discharge of condensed water have been strengthened.This device can not only be used for a remittance bowl bucket type drying cylinder, also can be used for the siphon tube type drying cylinder, also can use on other big-and-middle-sized steam-heated equipment.

Accompanying drawing 1 is vertical unit schematic representation of the present utility model (summary is with scheming);

Accompanying drawing 2 is the utility model liquid level relay sidepiece assembling schematic representation;

Accompanying drawing 3 is the utility model circuit theory diagrams.

Implementation example:

As shown in Figure 1, top at tank body 10 installs liquid level relay 1 with flange plate, the fork of its liquid level relay 1 feeds in the tank body 10, and ball float 7 is housed at the other end, be respectively equipped with pressure gauge 2, thermometer 4 and steam inlet duct 4 and secondary discharge tube 3 on the top of tank body 10, tank body 10 middle parts are provided with level indicator 6, condensed water discharge pipe 9 is equipped with in tank body 10 bottoms, which is provided with solenoid valve 8, malfunctioning for preventing solenoid valve 8, waste pipe 9 is provided with bypass tube, and bypass valve is housed, be provided with blowdown valve 11 in the bottom of tank body 10, be used to clean tank body 10.

The utility model can be made vertical (as accompanying drawing 1) according to the requirement of installation conditions, also can be made into horizontal (as accompanying drawing 2), and liquid level relay 1 is loaded on the middle part of tank body 10.
