Abstract

Disclosed is an automatic water discharging device of a closed container. The automatic water discharging device is connected in series in a circuit in the closed container through a float switch and a magnetic valve by an alternating current 220V power source, the float switch and the magnetic valve are placed at the bottom of the container, a normally-opened point of the float switch is enabled to be connected with a coil of the magnetic valve in series, when water enters in the container ceaselessly and a water level rises to the position of the float switch in the container, a float ball on the float switch floats upwards, a magnet in the float ball absorbs a magnetic reed switch to be closed for powering on, the coil of the magnetic valve is powered on, a valve is opened automatically, the water is discharged towards the outside of the container until the water is discharged cleanly, the float switch recovers to be in a normally-opened state, the power source is cut off, the coil of the magnetic valve is powered off and is closed, and the water in a tank body is discharged completely.

Description

The seal container self-draining arrangement

Affiliated technical field

The utility model relates to drainage means in a kind of airtight oil vessel, and the water of separating in the oil in the time of especially preventing unmanned the monitoring can not in time be discharged the generation of phenomenon.

Background technique

Well-known turbine oil plays lubricated and cooling action in steam turbine bearing, the quality quality of turbine oil directly has influence on the safety and economic operation of steam turbine set.In every index of quality quality of turbine oil one " water content " to be arranged be very important and weigh, turbine oil often is in operation because gland packing leakage or move improper steam or the water of making and bleed among the system, influence this index, because entering of water causes the bearing of turbo generator set vibration easily, influence the proper functioning of steam turbine unit, generally use the turbine oil water removal device and can in time separate moisture content in the turbine oil, and the water of separating can discharge timely be the prerequisite that guarantees the steam turbine set safe operation.

At present, the water that water removal device is separated in the known turbine oil and oil are present in the seal container usually jointly, because the density of turbine oil is littler than the density of water, oil can float over water above, water arrives container bottom in the effect deposit of gravity, and along with the water of separating constantly increases, the water liquid level can rise gradually, be artificial by the outside draining of valve generally speaking, the structure of artificial drainage is to be formed by combining by ball valve, Korea S's head, Φ 6 transparent pipes.With the container bottom perforate, weld one section and be with externally threaded pipeline, ball valve is screwed on the outside thread, refill and mix Korea S's head, Φ 6 transparent pipes are observed by form and to be opened ball valve when having water to enter in the seal container, and naked eyes have observed water from Φ 6 transparent pipes and discharged, when having oil to discharge, water is described by emptying, then throttle down.In this case, when seal container has water manually can not see the very first time is found, if water can not in time be discharged, is easy to cause the water that has just leached to get back to once more in the oil system, causes the secondary of W/O content to exceed standard, and influences the normal use of turbine oil.As the untimely ball valve of closing in the clean back of water discharging, also cause the generation of oil leak accident easily.

Summary of the invention

Can not in time discharge this deficiency for solving water, the utility model provides a kind of self-draining arrangement, this self-draining arrangement can not only detect the water liquid level in the seal container automatically, and can make things convenient for the recloser drain opening, namely efficiently solve the problem of timely draining, the hidden danger of having avoided water content to exceed standard prevents from running the generation of oily phenomenon again.

The technological scheme that its technical problem that solves the utility model adopts is: on the basis of manual drainage device, install a normally closed solenoid valve, seal container bottom arranges 180 ° of float switches, and (but this float switch proportion is greater than the proportion of turbine oil less than the proportion of water, it is normally open in oil, only ball float upwards floats in water, the closed energising of attraction magnetic reed switch in the ball float), float switch, solenoid valve are placed on container bottom, and float switch is connected with the solenoid valve energising.In container, there is water constantly to enter, when water level rises to container bottom float switch position, the closed energising of float switch, the solenoid valve energising is opened automatically, to the external container draining, after the water emptying, float switch reverts to normally open and cuts off the electricity supply, the electromagnetic valve coil dead electricity, closed electromagnetic valve, the water emptying in the expression container.This process does not need artificial draining regularly, can detect by the electrical control very first time, realizes timely self-draining purpose.

The beneficial effects of the utility model are, have discharged the moisture content of separating in the turbine oil timely, have saved the time for turbine profit index fast lifting, no longer need artificial discharging regularly, have avoided running the generation of oily phenomenon, make things convenient for the user, and are simple in structure.
