Description

Technical Field

[0001] The utility model relates to the field of temperature control valves, in particular to a vertical 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 vertical temperature control valve to solve the problems raised in the above-mentioned background technology, and the vertical temperature control valve has the advantage of controlling the flow rate of the fluid.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical temperature control valve, including a valve body, the valve body including a first connecting tube and a second connecting tube connected to the left and right, a third connecting tube is arranged between the first connecting tube and the second connecting tube, a limiting tube is installed in the third connecting tube, a connecting groove is arranged on one side of the limiting tube in the third connecting tube, the connecting groove is connected to the inside of the limiting tube, and a limiting member for movably closing the connecting groove is installed in the limiting tube.

[0005] By adopting the above technical solution, the connecting groove and the first connecting pipe are connected by using a limiter, and the fluid flowing into the first connecting pipe can enter the connecting groove, and then flow out from the lower end of the limiter pipe into the second connecting pipe, thereby realizing the opening or closing of the flow of the fluid. In this process, the rotation of the limiter is controlled to control the area size of the connecting groove and the first connecting pipe, thereby achieving the purpose of controlling the flow size of the fluid.

[0006] As a further solution of the utility model: the limiting member includes a connecting column, a cavity is arranged inside the connecting column, the lower end of the cavity is connected to the outside, and a flow groove is arranged on the side of the connecting column, which passes through the connecting column and is connected to the cavity, and the groove opening of the flow groove includes a first square groove, an arc-shaped groove, a second square groove and a triangular groove.

[0007] By adopting the above technical solution, when the connecting column rotates to the point where the first square groove, arc-shaped groove, second square groove and triangular groove are connected to the connecting groove, the fluid will flow through the connecting groove into the cavity and then flow out from the bottom of the cavity and flow into the second connecting tube. When the connecting column rotates to the point where the first square groove, arc-shaped groove, second square groove and triangular groove are not connected to the connecting groove, the first connecting tube and the second connecting tube will be in a disconnected state.

[0008] As a further solution of the present invention: the first square groove, the arc-shaped groove, the second square groove and the triangular groove are arranged in sequence and are interconnected.

[0009] By adopting the above technical solution, the opening areas of the first square groove, arc-shaped groove, second square groove and triangular groove are not the same. As the first square groove, arc-shaped groove, second square groove and triangular groove are respectively aligned with the connecting groove, the flow rate of the fluid flowing into the connecting column will change accordingly.

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

[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 rotating shaft is sleeved with a fixing sleeve at the top of the connecting column, a notch is arranged on one side of the fixing sleeve, and a rotating groove is also arranged on the side of the fixing sleeve to facilitate the rotation of the fixing sleeve.

[0013] By adopting the above technical solution, the setting of the notch makes it easy for the user to judge the condition of the connecting column according to the position of the notch, and the setting of the rotating groove makes it easy to rotate the fixing sleeve so that the notch is in the required position when the first connecting tube and the second connecting tube are in a disconnected state.

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

[0015] The connecting groove and the first connecting pipe are connected by means of a limiting member, and the fluid can flow into the connecting groove from the first connecting pipe, and then flow out from the lower end of the limiting pipe into the second connecting pipe, thereby opening or closing the flow of the fluid. In this process, the rotation of the limiting member is controlled to control the size of the area when the connecting groove and the first connecting pipe are connected, thereby achieving the purpose of controlling the flow rate of the fluid.
