The invention is an anti-blocking device of a heat supply system. A waste discharging and back washing hole is drilled at the back of a spherical valve core, and communicates directly with a drift diameter hole. A temperature sensor insertion hole is drilled under the spherical valve core, and communicates directly with the drift diameter hole. A hemispherical sieve projecting inwards is arranged at a mouth of the drift diameter hole at the water inlet side of the spherical valve core. The invention is provided with the advantage that the device can discharge sundries quickly without changing a part, the device is safe and causes no pollution to the environment, and the usable life of the device is prolonged.
Description
technical field [0001] The invention relates to an anti-blocking device for a heating system. Background technique [0002] At present, in order to prevent clogging in the heating system, a filter is installed on the side of the heat meter in the direction of water in advance. When the filter is blocked by impurities, the hot water operation has to be stopped, and the filter is manually dismantled and replaced, which is time-consuming. It costs materials again, and the temperature of the water in the heating network is high, so there is a potential safety hazard. Contents of the invention [0003] The object of the present invention is to overcome the above defects and provide an anti-blocking device for a heating system. [0004] The technical solution of the present invention is: an anti-blocking device for a heating system, which is characterized in that: a blowdown recoil hole communicating with the through hole of the valve core is drilled on the back of the ball-typ...
