Description

Technical Field

[0001] This utility model belongs to the field of lubrication system technology, specifically an integrated pressure relief valve for a centralized single-line lubrication system. Background Technology

[0002] In existing single-line lubrication systems, the pressure relief valve, safety valve, and lubrication pump are all connected via external pipelines. This connection method has significant shortcomings:

[0003] 1. The pipeline layout is messy and difficult to maintain;

[0004] 2. Installation is limited or even impossible in confined spaces.

[0005] Therefore, we propose an integrated single-line system pressure relief valve. Utility Model Content

[0006] The purpose of this invention is to provide an integrated single-line system pressure relief valve to solve the problems of messy pipelines and space occupation.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an integrated single-line system pressure relief valve, comprising:

[0009] Valve block;

[0010] Two-position, two-way solenoid valves are mounted on a valve block and are used to control the on / off state of the oil circuit.

[0011] Pump core through-hole bolts are located on the valve block and are used to directly connect the lubrication pump core.

[0012] Oil outlet P2 is connected to the lubrication pipeline and is used for oil discharge;

[0013] Oil return port T2 is used for pressure relief and oil return.

[0014] Safety valve, integrated into the valve block, is used to return oil when the pipeline is under overpressure;

[0015] The valve block has an internal oil passage to facilitate the flow of oil between the components.

[0016] In one embodiment, the valve block is also provided with spare oil outlets P3 and P4, which are sealed by plugs and can be connected to pressure gauges when needed.

[0017] In one embodiment, the valve block is also provided with spare oil return ports T3 and T4, which are sealed by plugs and can be connected to other accessories when needed.

[0018] In one embodiment, the valve block is an integral metal structure, and the internal oil passage includes:

[0019] Connect the main oil circuit of the pump core through-hole bolt to the two-position two-way solenoid valve;

[0020] Connect the two-position two-way solenoid valve to the working oil circuit of oil outlet P2;

[0021] Connect the safety valve to the pressure relief oil circuit of return port T2.

[0022] In one embodiment, the two-position two-way solenoid valve is normally open. When energized and closed, the oil flows to the oil outlet P2. When de-energized and opened, the oil is depressurized through the oil return port T2.

[0023] This utility model has the following beneficial effects:

[0024] This invention replaces the dispersed pipelines with valve block integration, thus replacing the traditional pipeline connection method and effectively solving the problem of messy connections, making the system structure more compact and neat.

[0025] The integrated structure of this utility model greatly reduces the overall space occupied, solves the problem of installation in small spaces, and improves the applicability of the system; the spare detection port supports pressure monitoring, improving the maintainability of the system.

[0026] The simplified structure of this utility model makes the installation process easier and reduces the difficulty of installation. It also reduces the risk of malfunctions such as leakage due to pipeline connections, thereby improving the reliability and stability of the system.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] Example 1

[0038] Please see Figures 1-3 As shown, this utility model is an integrated single-line system pressure relief valve, comprising:

[0039] Valve block 4;

[0040] Two-position two-way solenoid valve 1 is installed on valve block 4 and is used to control the oil circuit opening and closing;

[0041] Pump core through-hole bolt 2 is located on valve block 4 and is used to directly connect the lubrication pump core;

[0042] Oil outlet P2 is connected to the lubrication pipeline and is used for oil discharge;

[0043] Oil return port T2 is used for pressure relief and oil return.

[0044] Safety valve 3, integrated within valve block 4, is used to return oil when the pipeline is under overpressure;

[0045] The valve block 4 has an internal oil passage to facilitate the flow of oil between the components.

[0046] Furthermore, valve block 4 is also equipped with spare oil outlets P3 and P4, which are sealed by plugs and can be connected to pressure gauges when needed.

[0047] Furthermore, the valve block 4 is also equipped with spare oil return ports T3 and T4, which are sealed by plugs and can be connected to other accessories when needed.

[0048] Furthermore, valve block 4 is an integral metal structure, and its internal oil passages include:

[0049] Connect the main oil circuit of the pump core through-hole bolt 2 to the two-position two-way solenoid valve 1;

[0050] Connect the working oil circuit of the two-position two-way solenoid valve 1 to the oil outlet P2;

[0051] Connect safety valve 3 to the pressure relief oil circuit of return port T2.

[0052] Furthermore, the two-position two-way solenoid valve 1 is normally open. When energized and closed, the oil flows to the outlet port P2. When de-energized and opened, the oil is depressurized through the return port T2.

[0053] Example 2

[0054] Please see Figure 3 As shown in the figure, this embodiment illustrates the working principle and process of an integrated single-line system pressure relief valve: When the lubrication pump starts working, the two-position two-way solenoid valve 1 is simultaneously energized. Since the two-position two-way solenoid valve 1 is normally open, the oil circuit closes after energization. At this time, the medium flowing from the pump core can only flow to the lubrication pipeline through the oil outlet P2 port. When the pipeline pressure reaches the set value, the pump stops working, the two-position two-way solenoid valve 1 is de-energized, and the oil circuit opens after de-energization. The pressure in the oil circuit flows to port T2 through the two-position two-way solenoid valve 1, completing the pipeline pressure relief. During pump operation, if the pressure in the pipeline exceeds the set value of the safety valve 3, the safety valve 3 will automatically relieve pressure and allow the oil to flow out through port T2, thereby ensuring that the pressure in the pipeline does not exceed the set value.

[0055] Further explanation is needed regarding the functions or roles of each component: the two-position two-way solenoid valve 1 can open or close the oil circuit; the pump core through-hole bolt 2 serves to connect the pump; the oil outlet P2 is used to output oil; the oil return port T2 is used for oil return; the safety valve 3 enables oil return when the pipeline is under overpressure, ensuring pipeline safety; the valve block 4 has a specific oil circuit design to achieve oil flow between the components.
