The utility model has the beneficial effects that: according to the heat supply pipeline condensed water collecting and discharging structure, the direct-current pipeline and the U-shaped pipeline which are connected in parallel can be used for high-temperature steam to pass through, wherein the height of the U-shaped pipeline is lower than that of the direct-current pipeline, so that most of condensed water flows into the U-shaped pipeline and is collected by the U-shaped pipeline, once the U-shaped pipeline is blocked due to the fact that the condensed water in the U-shaped pipeline cannot be discharged timely, the high-temperature steam can be discharged from the direct-current pipeline, and the phenomenon that the pressure in the pipeline is overhigh due to pipeline blockage is avoided. During the comdenstion water accessible drain pipe drainage condensate water collector of collecting in the U-shaped pipeline, because the overflow mouth highly is higher than the collector pipe export, consequently the export of collector pipe can be submerged in the comdenstion water in the use, utilizes comdenstion water separation steam, reduces steam leakage, and the cooperation relief pressure valve can further reduce steam leakage simultaneously. When the liquid level of condensed water collected in the tank body exceeds the overflow port, the condensed water can be automatically discharged from the overflow port, part of water vapor leaked into the tank body can be condensed into condensed water in the tank body, if the leaked steam is too much, the pressure in the tank body is increased, and when the pressure reaches the threshold value of the pressure release valve, the pressure release valve is opened to discharge the steam.

Preferably, a return pipe is connected to the overflow opening and is formed with a U-shaped pipe section. The U-shaped pipe section of the return pipeline can form accumulated water when in use, and the accumulated water can prevent steam from directly leaking from the overflow port.

Preferably, the tank of the condensed water collector is further provided with a water filling port, and a normally closed valve is arranged on the water filling port. The water can be directly added into the tank body by the water adding port, so that accumulated water can be formed in the tank body before the water discharging pipe is connected to achieve the effect of blocking steam.

Preferably, the outlet of the pressure relief valve is connected with a discharge pipe, and the discharge pipe is of an inverted U-shaped structure. The discharge pipe of the inverted U-shaped structure can prevent accumulated water from being formed in the discharge pipe to block steam discharge.

Preferably, the bottom of the tank body of the condensed water collector is also connected with an emptying pipe with a valve. The accumulated water in the condensed water collector can be discharged by utilizing the emptying pipe so as to clean the inside of the tank body.
