It is highly efficient and stable and is widely used in various industrial fields. The triple pump control valve group is a valve combination used to control the outlet fluid of the triple pump. By adjusting the opening of the control valve, the parameters such as fluid flow and pressure can be adjusted to meet the needs of different working conditions, that is, there are difficulties in the pipeline connection of the triple pump outlet valve control valve group. Due to the inflexible design of the pipeline connection and the difficulty in installation and adjustment, it is inconvenient to operate in actual projects, affecting the normal operation and maintenance of the equipment.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The following is combined with Figure 1-6 The specific implementation modes of the present utility model are further described in detail.

[0021] In this embodiment, by Figure 1 As shown in FIG. 6 , the utility model includes a valve block 1, wherein the valve block 1 is fixedly connected with two first oil inlets 2, the two first oil inlets 2 are connected with a first pipeline 3 provided in the valve block 1, the two first pipelines 3 are connected with a first pressure port 4 fixed on the valve block 1, the two first pipelines 3 are connected with a second pipeline 5 provided in the valve block 1, the two second pipelines 5 are connected with a first unloading port 6 provided on the valve block 1, the valve block 1 is provided with a second oil inlet 7, the second oil inlet 7 is connected with a third pipeline 8 provided in the valve block 1, the third pipeline 8 is connected with a fourth pipeline 9 provided inside the valve block 1, the third pipeline 8 is connected with a second pressure port 10 fixed on the valve block 1, the fourth pipeline 9 is connected with a second unloading port 11 fixed on the valve block 1, a main overflow valve 12 is provided at the connection between the first pipeline 3 and the second pipeline 5, a proportional overflow control valve 13 is installed on the main overflow valve 12, and an electromagnetic overflow valve 14 is provided at the connection between the third pipeline 8 and the fourth pipeline 9;

[0022] The model selected for the electromagnetic relief valve 14 is RVCKLJN924, the model selected for the main relief valve 12 is RPGC8WN, and the model selected for the proportional relief valve is RBAPXWN924.

[0023] In this embodiment, by Figure 1-2 and Figure 6 As shown, the first pipeline 3 and the third pipeline 8 are both connected to a pressure measuring port 15 fixed on the valve block 1, and a pressure gauge 16 threadedly connected to the valve block 1 is provided at the pressure measuring port 15, and the model of the pressure gauge 16 is YN-63-IV40.

[0024] In this embodiment, by Figure 1-5 As shown, the valve block 1 is provided with a one-way valve 17 and a pressure sensor 18 which are threadedly installed in the first pipeline 3 and the third pipeline 8. The one-way valve 17 is of the model CXFAXCN, and the pressure sensor 18 is of the model TRAFAG8252.

[0025] In this embodiment, by Figure 1-4 As shown, the electromagnetic overflow valve 14 and the main overflow valve 12 are both threadedly connected to the valve block 1 , and the proportional overflow control valve 13 is threadedly connected to the main overflow valve 12 .

[0026] In this embodiment, by Figure 1-6 As shown, the first unloading port 6 and the second unloading port 11 are both connected to the main unloading port 19 .

[0027] When the utility model is used, the oil enters the first pipeline 3 and the second pipeline 5 in the valve block 1 from the first oil inlet 2 and the second oil inlet 7. The oil in the first pipeline 3 first passes through the pressure gauge 16, and then passes through the main overflow valve 12 and the proportional overflow control valve 13. The main overflow valve 12 and the proportional overflow control valve 13 will control the oil flow rate and flow rate for regulation. When the oil pressure is lower than the set value, the oil flows from the first pipeline 3 through the main overflow valve 12 and the proportional overflow control valve 13 and then flows out from the check valve 17 to the first pressure port 4. When the oil pressure is too large, the main overflow valve 12 and the proportional overflow control valve 13 are used to control the oil to flow out from the first unloading port 6, thereby adjusting the oil hydraulic pressure. Similarly, when the oil pressure of the oil entering the second oil inlet 7 is lower than the set value, the oil flows from the third pipeline 8 through the electromagnetic overflow valve 14 and then flows out from the one-way valve 17 to the second pressure port 10. When the oil pressure is too high, the electromagnetic overflow valve 14 is used to control the oil to flow out from the fourth pipeline 9 to the second unloading port 11, thereby adjusting the oil pressure. The oil flow is controlled by the triple pump outlet control valve group used for the drainage robot. The pipeline is opened in the valve block 1, and multiple one-way valves 17, the main overflow valve 12, the proportional overflow control valve 13, and the electromagnetic overflow valve 14 are integrated on the valve block 1, thereby reducing the connection of external pipelines and reducing the occupied space.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
