Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1, the medium-pressure condensate water tank comprises a main body 1 made of polyethylene, an end cap 2 and a drain pipe 3, wherein the main body 1 is a four-way pipe, the lower part of the main body 1 is in hot-melt welding with the end cap 2, the upper part of the main body 1 is in hot-melt welding with the drain pipe 3, the drain pipe 3 is vertically inserted into the main body 1 to the end cap 2, and the upper end of the drain pipe 3 extends out of the main body 1.

The upper part of the drain pipe 3 is provided with a drainage device, and one side of the drainage device is provided with a bypass device; the drainage device comprises an electric melting sleeve a9, a connecting pipe a10, an electric melting tee a11, an electric melting reducing pipe a12, an electric melting sleeve b13, a PE ball valve a14, an electric melting tee b15 and a screw thread steel-plastic conversion joint 16 which are sequentially connected from the upper part of a drainage pipe 3; the bypass device comprises a right-angle electric melting elbow a17, a connecting pipe b18, an electric melting reducing pipe b19, a PE ball valve b20 and a right-angle electric melting elbow b21 which are sequentially connected from an electric melting tee joint a11 to an electric melting tee joint b 15.

Referring to fig. 2, 3 overcoat at the inside drain pipe of main part 1 is equipped with floating collar 4, and the internal diameter of floating collar 4 is greater than the external diameter of drain pipe 3, and hot melt welding has an outer sealing ring 5 on the outer lane of floating collar 4, and floating collar 4 can follow the axial and reciprocate, and outer sealing ring 5 supports on the inner wall of main part 1 or end cap 2, and the equal smooth setting of inner wall of main part 1 and end cap 2 has all seted up round annular 51 on the upper and lower terminal surface of outer sealing ring 5. Hot melt welding has round boss 6 on the bottom outer wall of drain pipe 3, 6 up end of boss is equipped with round inner seal circle 7, the external diameter of inner seal circle 7 is greater than the internal diameter of floating collar 4, be equipped with elastic component 8 between floating collar 4 and boss 6, elastic component 8 is compression spring, the outside of drain pipe 3 and inner seal circle 7 is located to elastic component 8 cover, elastic component 8's both ends support between floating collar 4 and boss 6, elastic component 8 makes floating collar 4 have the trend of keeping away from 6 direction movements of boss, under the state of no external force, floating collar 4 and inner seal circle 7 contactless, the minimum height that elastic component 8 is compressed back is less than inner seal circle 7 is high.

In actual use, the condensed water 22 formed in the medium-pressure water condensing cylinder flows into the end cap 2 along the gap between the floating ring 4 and the water discharging pipe 3, and when the water level of the condensed water 22 is higher than the natural height of the elastic member 8, the floating ring 4 floats by virtue of buoyancy, as shown in fig. 3. When a worker needs to maintain the medium-pressure condensate tank and pump away the condensate in the medium-pressure condensate tank, the worker firstly connects the water pipe of the water pump with the screw thread steel-plastic adapter 16 on the drainage device, and after the water pump is started, the worker can open one PE ball valve a14 or PE ball valve b20 at will or open all the PE ball valves a14 or the PE ball valves b20, so that the condensate 22 in the end cap 2 can be drained through the drain pipe 3, the drainage device or the bypass device. Referring to fig. 4, when the water level of the condensed water 22 reaches the highest point of the inner sealing ring 7, due to the negative pressure formed by pumping, the floating ring 4 extrudes the elastic member 8 until the floating ring 4 abuts against the inner sealing ring 7, so that a relatively closed space is formed below the floating ring 4, the gradually increased internal pressure can reduce the amount of pumped water, and at this time, a worker can know that the condensed water is almost pumped, and then close the PE ball valve a14 and the PE ball valve b20 to finish the pumping operation. After the water pump is closed, the pressure below the floating ring 4 is instantly reduced, and the floating ring 4 can be immediately pushed away upwards along with the combined action of the reflowing condensed water 22 and the elastic piece 8, so that the floating ring 4 is separated from the inner sealing ring 7, a closed space is eliminated, and the condensed water is ensured to normally flow into the end cap 2, as shown in fig. 5. In the whole pumping process, the condensed water which submerges the inlet height of the water discharge pipe 3 is always reserved in the end cap 2 to play a role of water seal, so that the gas leakage caused by pumping is prevented.
