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 the external diameter of floating collar 4 is less than the internal diameter of end cap 2 inner wall, and the outer wall of drain pipe 3 and the equal smooth setting of inner wall of end cap 2, floating collar 4 can follow the axial and reciprocate. The outer wall of the bottom of the drain pipe 3 is welded with a circle of inner bosses 5 in a hot melting mode, the inner wall of the bottom of the end cap 2 is welded with a circle of outer bosses 6 in a hot melting mode, the upper end faces of the inner bosses 5 and the outer bosses 6 are parallel and level, the upper end face of the inner boss 5 is bonded with a circle of inner sealing ring 7, the outer diameter of the inner sealing ring 7 is larger than the inner diameter of the floating ring 4, the upper end face of the outer boss 6 is bonded with a circle of outer sealing ring 8, the inner diameter of the outer sealing ring 8 is smaller than the outer diameter of the floating ring 4, the upper end faces of the inner sealing ring 7 and the outer sealing ring 8 are parallel and level, an elastic piece 22 is arranged between the floating ring 4 and the inner boss 5 or the outer boss 6, in the embodiment, the elastic piece 22 is a compression spring, the elastic piece 22 is sleeved on the outer side of the inner sealing ring 7 and arranged on the upper end face of the, in the state without external force, the floating ring 4 is not in contact with the inner sealing ring 7 and the outer sealing ring 8, and the minimum height of the compressed elastic piece 22 is lower than the heights of the inner sealing ring 7 and the outer sealing ring 8.

In actual use, the condensed water 23 formed in the medium-pressure condensing cylinder flows into the end cap 2 along the gap between the floating ring 4 and the outer wall of the drain pipe 3 and the inner wall of the end cap 2, and when the water level of the condensed water 23 is higher than the natural height of the elastic member 22, 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 water 23 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 freely open one PE ball valve a14 or PE ball valve b20 or completely open the water pump, so that the condensate water 23 in the end cap 2 can be discharged through the drainage pipe 3, the drainage device or the bypass device. Referring to fig. 4, when the water level of the condensed water 23 reaches the highest point of the elastic member 22, due to the negative pressure formed by pumping, the floating ring 4 extrudes the elastic member 22 until the floating ring 4 abuts against the inner sealing ring 7 and the outer sealing ring 8, 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 23 is almost pumped, close the water pump first, and then close the PE ball valve a14 and the PE ball valve b20, thereby completing 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 backflow condensed water 23 and the elastic piece 22, so that the floating ring 4 is separated from the inner sealing ring 7 and the outer sealing ring 8, 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.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
