Description

Technical Field

[0001] The utility model relates to the field of temperature control valves, in particular to a current limiting temperature control valve. Background Art

[0002] Temperature control valve is a very important component in heating system, which mainly plays the role of regulating flow in the system. The existing temperature control valve can only control the opening or closing of fluid flow, but cannot control the flow rate of fluid, so it needs to be improved. Utility Model Content

[0003] The utility model aims to provide a flow-limiting temperature control valve to solve the problems raised in the above-mentioned background technology, and the utility model has the advantage of controlling the flow rate of a fluid.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flow-limiting temperature control valve, including a valve body, the valve body including a first connecting tube and a second connecting tube distributed on the left and right, a third connecting tube is arranged between the first connecting tube and the second connecting tube, the first connecting tube, the second connecting tube and the third connecting tube are connected to each other, an installation tube is threadedly connected to the first connecting tube, and a limiting member for movably closing the third connecting tube is arranged in the installation tube.

[0005] By adopting the above technical solution, the circulation flows in from the third connecting tube. When the limiting member closes the third connecting tube, the fluid cannot flow from the third connecting tube into the second connecting tube. When the limiting member no longer closes the third connecting tube, the fluid will flow from the third connecting tube into the second connecting tube, thereby playing the role of opening and closing the flow of the fluid.

[0006] As a further solution of the utility model: the limiting member includes a connecting column in the installation tube, the connecting column can rotate around its own axis, the lower end of the connecting column is provided with an empty groove, and the side of the connecting column is provided with a flow groove connected to the empty groove.

[0007] By adopting the above technical solution, the opening area of ​​the circulation groove is constant. When the opening of the circulation groove is aligned with the pipe mouth of the third connecting tube, the flow rate of the fluid flowing from the third connecting tube to the second connecting tube is the largest. As the connecting column rotates, the opening of the circulation groove will be in a moving process. At this time, the area of ​​the circulation groove when connected with the pipe mouth of the third connecting tube will become smaller, thereby playing a role in controlling the size of the fluid flow rate.

[0008] As a further solution of the utility model: the side surface of the connecting column is provided with an inwardly recessed triangular groove, and one side of the triangular groove is connected to the flow groove.

[0009] By adopting the above technical solution, the connecting column is rotated until the triangular groove is at the pipe mouth of the third connecting tube. At this time, the fluid flowing out of the third connecting tube will flow along the triangular groove and pass through the circulation groove into the empty groove, and then flow from the empty groove to the second connecting tube. When different triangular grooves are located at the pipe mouth of the third connecting tube, the fluid in the third connecting tube will have a corresponding flow rate flowing into the triangular groove, thereby controlling the flow rate of the fluid flowing out of the third connecting tube.

[0010] As a further solution of the utility model: a rotating shaft is integrally connected to the top of the connecting column.

[0011] By adopting the above technical solution, the setting of the rotating shaft facilitates the rotation of the connecting column.

[0012] As a further solution of the utility model: the upper end of the connecting column is provided with a polygonal block sleeved on the rotating shaft.

[0013] By adopting the above technical solution, the rotating shaft is driven to rotate by rotating the polygonal block, which makes it easy to rotate the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The circulation flows in from the third connecting tube. When the limiting member closes the third connecting tube, the fluid cannot flow from the third connecting tube into the second connecting tube. When the limiting member no longer closes the third connecting tube, the fluid will flow from the third connecting tube into the second connecting tube, thereby opening and closing the flow of the fluid.
