Description

Technical Field

[0001] The utility model relates to the technical field of floor heating engineering, in particular to a large flow valve for floor heating engineering. Background Art

[0002] Floor heating project, also known as floor radiation heating project, works on the principle of evenly heating the entire floor through the heat medium in the floor radiation layer, and using the ground's own heat distribution and the law of heat radiation upward to conduct heat from bottom to top to achieve the purpose of heating. Floor heating system mainly consists of floor heating heat distribution layer, insulation layer, heating pipe, water distributor and water collector. The large flow valve in floor heating project is one of the commonly used accessories in floor heating system. Its function is to adjust the flow of hot water in the pipe, and then adjust the heating capacity of floor heating system. The large flow valve can adjust the water flow by changing the opening of the outlet.

[0003] Common large-flow valves for floor heating projects are usually composed of valve bodies, valve cores, handles or actuators, seals, and connectors. First, lay the floor heating pipes, install the regulating valves on the pipes, add horizontal pipes between the regulating valves and the floor heating valves, connect the floor heating pipes to the valves, and test and debug them. This is the common structure and use of large-flow valves for floor heating projects. After long-term use, the impurities in the water of the floor heating project will cause blockage inside the large-flow valves, and will also cause corrosion to the valves, which will not only damage the valve structure, but also affect its sealing and service life, and also affect the normal operation of the valves. Some large-flow valves for floor heating projects add a filtering structure at one end of the valve, such as a filter screen, to intercept and separate the impurities in the water, so as to prevent the impurities from entering the interior of the large-flow valve with the water flow and causing blockage and corrosion. However, in this way, as the large-flow valve is used for a long time, impurities in the water are concentrated at one end of the filter structure and piled up, which is difficult to clean, thereby affecting the speed at which water passes through the large-flow valve in the floor heating project, and even preventing the water from passing through the valve. This not only affects the water flow of the floor heating system, but also causes the heating effect of the floor heating system to decrease. Therefore, a large-flow valve for floor heating projects is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a large flow valve for floor heating projects to solve the technical problem that impurities in the water accumulate on the filter structure and are inconvenient to clean.

A filter plate is provided at the center of the inner cavity of the filter box, and triangular scrapers are provided at the upper and lower parts of one side of the filter plate.

[0010] The guide rod is arranged at the upper and lower parts of the center of one side of the filter box, and the inner ends of the guide rods extend inward through the outer wall of the filter box and are connected to the corresponding triangular scrapers. The valve housing, the liquid inlet pipe and the liquid outlet pipe are used to realize the large flow of liquid in the floor heating project, and the filter plate in the filter box separates the impurities in the liquid. When not in use, the guide rod can be squeezed to drive the triangular scraper to move along the surface of the filter plate and clean the impurities blocked on the surface of the filter plate. On the one hand, the impurities on the filter plate can be cleaned to avoid impurities distributed on the filter plate to form blockage; on the other hand, the guide rod drives the triangular scraper to move along the filter box, thereby ensuring that the triangular scraper moves horizontally to avoid the phenomenon of incomplete cleaning of the filter plate.

[0011] Preferably, a rotating handle is vertically provided at the top center of the valve housing, and the valve housing and the rotating handle are rotatably connected. The rotating handle can drive the structure inside the valve housing to rotate, thereby controlling the flow and closing operation of the liquid.

[0014] Preferably, side blocking plates are provided at the upper and lower parts of the center position of the other side of the filter box, and the side blocking plates correspond to the triangular scraper plates, and a connecting rod is connected between the side blocking plates and the triangular scraper plates. When the triangular scraper plates move, the side blocking plates are driven to move in the same direction by the connecting rods, and when the triangular scraper plates move impurities on one side of the filter plate to the other side, the impurities can be pushed out of the filter box, thereby removing the impurities on the filter plate to the outside of the filter box, and preventing the impurities from being retained inside the filter box and causing blockages.

[0015] Preferably, a material receiving plate is installed at the lower part of the other side of the filter box, and a rotating rod is installed transversely at the upper and lower parts of one side of the filter box, and the outer end of the rotating rod is rotatably connected to a limit head, and the limit head corresponds to the limit plate. The material receiving plate can collect the pushed impurities for centralized processing, and the limit plate can be pressed against the limit head of the rotating rod to prevent the limit plate from driving the connection structure to move when it is squeezed by the outside world, so as to cause the flowing liquid in the floor heating project to leak.

[0027] The guide rod 8 is arranged at the upper and lower parts of the center of one side of the filter box 5, and the inner ends of the guide rod 8 extend inward through the outer wall of the filter box 5 and are connected to the corresponding triangular scraper 7. The large flow of liquid in the floor heating project is realized through the valve housing 1, the liquid inlet pipe 3 and the liquid outlet pipe 4, and the filter plate 6 in the filter box 5 separates the impurities in the liquid. When not in use, the guide rod 8 can be squeezed to drive the triangular scraper 7 to translate along the surface of the filter plate 6, and the impurities blocked on the surface of the filter plate 6 can be cleaned. On the one hand, the impurities on the filter plate 6 can be cleaned to avoid impurities distributed on the filter plate 6 to form blockage; on the other hand, the guide rod 8 drives the triangular scraper 7 to move along the filter box 5, thereby ensuring.
