Description

Technical Field

[0001] The utility model relates to the technical field of floor heating system installation components, in particular to a floor heating manifold valve. Background Art

[0002] Geothermal heating is a heating method that uses hot water not higher than 60°C as a heat medium, which circulates in the heating pipes, heats the floor, and supplies heat to the indoor space through the ground by radiation and convection. With the progress of the times, floor heating has been widely popularized in northern my country. The floor heating system generally includes a heating boiler and a floor heating manifold connected to the heating boiler through a pipe system. The floor heating manifold is an indispensable part of the floor heating system. It consists of a water distribution main and a water collection main. The water distribution main is connected to the water supply pipe of the pipe network system. Its main function is to distribute the hot water from the pipe network system to each room that needs floor heating through the floor heating pipes buried under the floor. The water collection main collects the hot water output by the floor heating pipes in each room and collects it back into the pipe network system for heating. Ball valves are generally installed on the pipes of the pipe network system to connect or close the heating boiler and The connection between the manifolds often requires a pressure gauge or a thermometer to be installed on the pipeline to monitor the pressure or temperature of the heating fluid in the pipeline according to customer needs. Therefore, it is often necessary to connect the ball valve, pressure gauge joint and thermometer joint in sequence on the pipeline. At the same time, since the heating fluid in the manifold network system is hot water, more scale will be produced during the long heating and cooling process. Excessive scale flows with the heating fluid, and eventually the control valve cannot be completely closed, resulting in failure of the control valve and affecting the heating effect. Therefore, filtering devices need to be installed in sequence on the pipeline.

[0003] After searching, the Chinese patent publication number CN205332341U discloses a multifunctional valve for a manifold, including a valve body and a reserved interface arranged on the side wall of the valve body, the valve body is provided with a filtering device and a manual regulating valve, the manual regulating valve controls the connection or disconnection of the main pipe, and by setting the reserved interface, a pressure gauge and a temperature gauge can be installed at the same time, and the pressure and temperature monitoring can be realized at the same time. At the same time, a manual regulating valve and a filtering device are arranged on the valve body, and the pressure and temperature monitoring, the main pipe shutoff and the filtering of the heating fluid are realized on one valve body, which solves the technical problem that the valves connected in sequence on the existing manifold pipeline occupy more space, and provides a multifunctional valve for a manifold integrating monitoring, filtering and disconnection functions.

[0004] The above patent has the following shortcomings: the heating liquid is filtered by setting a filtering device, but it is inconvenient to remove and replace the filter in the filtering device, which will affect the filtering effect after a long time.

[0005] In view of this, we propose the floor heating manifold valve. Utility Model Content
