Detailed Description

In order to make the objects, technical solutions, and achievement of the objects and effects of the present utility model comprehensible, preferred embodiments accompanied with figures are described in detail below for understanding by a skilled person.

It should be noted that, in the description of the present utility model, unless explicitly specified or limited, terms such as "mounted," "connected," and the like are to be construed broadly and may be either fixed or removable; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium.

As shown in fig. 1-4, the automatic drainage device of the split cylinder comprises a first stop valve 3, a drain valve 4, a second stop valve 5, an electromagnetic valve 6 and a capacitance type liquid level meter 8, wherein a drain pipe 11 for draining condensed water is arranged at the bottom of the split cylinder 1, the drain pipe 11 is connected with a water pipeline through a flange, the water pipeline is divided into a main drain pipe 2 and a secondary drain pipe 20, the main drain pipe 2 is connected with the first stop valve 3, the first stop valve 3 is connected with the drain valve 4 through a pipeline, and the drain valve 4 is connected with the second stop valve 5 through a pipeline. The electromagnetic valve 6 is connected with the drain valve 4 in parallel through a pipeline, an interface of the parallel pipeline is positioned between the two stop valves, and the auxiliary drain pipe 20 is provided with a third stop valve 7 which is convenient for a worker to overhaul. In a normal working state, the first stop valve 3 and the second stop valve 5 are opened, the drain valve 4 and the third stop valve 7 are closed, condensed water flows into the water inlet 21 from the drain pipe 11 at the bottom of the split cylinder 1, passes through the first stop valve 3, the electromagnetic valve 6 and the second stop valve 5, and is discharged from the water outlet 22.

In this embodiment, as shown in fig. 3, a bracket 9 is fixedly installed above the drain hole inside the split cylinder 1, a fixing hole is formed on the bracket 9 corresponding to the connecting flange 81, and the capacitive liquid level meter 8 is fixed by a bolt and a nut, so that the metal rod 82 of the capacitive liquid level meter 8 and the drain hole at the bottom of the split cylinder 1 are coaxial, and the measurement accuracy of the capacitive liquid level meter 8 is ensured. The capacitive liquid level meter 8 and the electromagnetic valve 6 are connected with the PLC, an upper limit value and a lower limit value are set for the capacitive liquid level meter 8, when the liquid level reaches the upper limit value, the PLC controls the electromagnetic valve 6 to be opened for drainage, and when the liquid level descends until the liquid level reaches the lower limit value, the PLC controls the electromagnetic valve 6 to be closed, automatic drainage is achieved, untimely or excessive drainage of condensed water drainage is avoided, and the drainage quality is improved. When the electromagnetic valve 6 fails, the electromagnetic valve 6 is manually closed, manual drainage is performed through the drain valve 4, and because the capacitance type liquid level meter 8 monitors the water level of condensed water in real time, the manual drainage can be more accurate, the frequency and the duration of the drainage are avoided through experience judgment of an operator, and the normal operation of the production line is ensured.

In this embodiment, when the drain valve 4 or the electromagnetic valve 6 needs to be overhauled, the first stop valve 3 and the second stop valve 5 are closed, temporary drain is performed through the third stop valve 7, and normal operation of the production line is ensured.

On the basis of the embodiment, because the large-sized automatic drain valve is high in price and large in batch replacement cost, the method adopting the parallel electromagnetic valve 6 can achieve the same effect while reducing the cost, and when the electromagnetic valve 6 fails, the capacitance type liquid level meter 8 can be electrified to perform more accurate manual drain, so that the normal operation of the production line is ensured.
