Description

Technical Field

[0001] The utility model relates to a temperature control valve installation joint for a radiator, in particular to a temperature control valve installation joint suitable for a parallel flow type hydraulic oil radiator. Background Art

[0002] At present, conventional hydraulic oil radiators on the market are divided into plate-fin hydraulic oil radiators and parallel flow hydraulic oil radiators. Hydraulic oil radiators usually install built-in thermostatic control valves (also known as temperature control valves) at the inlet of the radiator. The thermostatic valves will automatically control and adjust the oil volume of the radiator according to the set temperature requirements, so as to achieve the purpose of controlling the temperature inside the radiator. The oil chamber of the plate-fin hydraulic oil radiator is cast. In this structure, the cavity of the temperature control valve can be easily combined with the oil chamber of the plate-fin hydraulic oil radiator through casting. After the entire radiator is completed, just tighten the temperature control valve to the cavity through threaded connection. However, since the end of the parallel flow hydraulic oil radiator is designed with a manifold, the cavity of the temperature control valve cannot be processed due to structural limitations, and the built-in temperature control valve does not advocate vertical installation (because the thermal effect of the valve body and the surface pipe will cause the thermostatic controller to erroneously operate), so how to install the temperature control valve on the parallel flow hydraulic oil radiator has always been a technical difficulty.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides a temperature control valve installation joint suitable for a parallel flow hydraulic oil radiator, the temperature control valve installation joint mainly comprises two parts: a connecting bracket and a cavity. Among them:

[0024] The structure of the connecting bracket 6-1 is as follows Figure 1-2 As shown, it mainly includes a header connection port 6-1-1, a first bolt hole 6-1-2, a header adapter surface 6-1-3, a radial sealing groove 6-1-4, and a cavity matching surface 6-1-5. A through hole is provided on the connection bracket 6-1, the inner end of the through hole is the header connection port 6-1-1, and the outer end of the through hole is provided with a radial sealing groove 6-1-4.

[0025] The structure of the cavity 6-2 is as follows Figure 3-4 As shown, it mainly includes a second bolt hole 6-2-1, a temperature control valve oil inlet 6-2-2, a temperature control valve oil outlet 6-2-3, a connecting bracket docking port 6-2-4, an O-ring 6-2-5, and a temperature control valve mounting hole 6-2-6. The interior of the cavity 6-2 is a hollow structure, which has an upper end face, a lower end face, a left side face, a right side face, an inner side face, and an outer side face. The left side face of the cavity 6-2 is provided with a temperature control valve oil inlet 6-2-2 and a temperature control valve oil outlet 6-2-3 connected to the interior of the cavity 6-2, and the temperature control valve oil inlet 6-2-2 and the temperature control valve oil outlet 6-2-3 are arranged side by side in the longitudinal direction. The hollow structure between the temperature control valve oil inlet 6-2-2 and the temperature control valve oil outlet 6-2-3 forms a passage for the oil to flow through. The inner side of the cavity 6-2 is provided with a connection bracket docking port 6-2-4 connected to the temperature control valve oil inlet 6-2-2. The lower end surface of the cavity 6-2 is provided with a temperature control valve mounting hole 6-2-6, and the temperature control valve (not shown in the figure) penetrates into the cavity 6-2 through the temperature control valve mounting hole 6-2-6 and is installed in the cavity 6-2. The temperature control valve is used to control the on-off of the passage between the temperature control valve oil inlet 6-2-2 and the temperature control valve oil outlet 6-2-3.

[0026] like Figure 5-7As shown, when the temperature control valve is installed on the parallel flow hydraulic oil radiator by using the utility model, the arc-shaped manifold adapter surface 6-1-3 of the connecting bracket 6-1 is fitted with the side of the manifold 2, and the connecting bracket 6-1 is fixed to the side of the manifold 2 through the first bolt holes 6-1-2 and bolts around the connecting bracket 6-1, the manifold connecting port 6-1-1 of the connecting bracket 6-1 is brazed with the oil inlet 3 on the manifold of the parallel flow hydraulic oil radiator, and then the connecting bracket docking interface 6-2-4 of the cavity 6-2 is docked with the radial sealing groove 6-1-4 on the outside of the connecting bracket 6-1, and is sealed and connected through the O-ring on the outside of the bracket docking interface 6-2-4, and then the inner side surface of the cavity 6-2 is connected and fixed to the cavity matching surface 6-1-5 of the connecting bracket 6-1 through the second bolt holes 6-2-1 and bolts around the connecting bracket docking interface 6-2-4.

[0027] When the oil temperature is low, the temperature control valve is used to make the passage between the oil inlet and the oil outlet of the temperature control valve in a conducting state. At this time, since the flow resistance in the radiator core is greater than the flow resistance between the oil inlet and the oil outlet of the temperature control valve, the oil hardly flows through the core to dissipate heat, but mainly flows in from the oil inlet of the temperature control valve and directly flows out from the oil outlet of the temperature control valve; when the oil temperature is high, the temperature control valve is used to make the passage between the oil inlet and the oil outlet of the temperature control valve in a cut-off state. At this time, the oil flowing in from the oil inlet of the temperature control valve will flow from the radiator oil inlet through the radiator core to dissipate heat, and then flow out from the oil outlet of the temperature control valve.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
