Description

Technical Field

[0001] This utility model relates to the technical field of filter bypass valves, specifically an improved filter bypass valve. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. Oil filters are equipped with bypass valves. When the external temperature drops to a certain value or when the oil filter exceeds its normal service life, the bypass valve will open under special pressure, allowing unfiltered oil to flow directly into the engine.

[0003] Currently, most filter bypass valves are located on the top of the end cap, and a spring applies pressure to the valve plate without limiting the spring. This can easily cause the valve plate to become misaligned, affecting the flow of the bypass valve and resulting in poor performance of the bypass valve. Utility Model Content

[0026] Please see Figure 1-3 This utility model provides an embodiment of an improved filter bypass valve: An improved filter bypass valve includes an end cap 1 and a valve plate 3. The end cap 1 includes a slot 101 and a groove 102. The slot 101 is opened inside the end cap 1, which can install the end cap 1 at the bottom of the filter. The groove 102 is opened at the bottom end inside the slot 101. The valve plate 3 includes a sealing block 301, a positioning rod 303 and a spring 304. The sealing block 301 is located at the bottom end of the valve plate 3. The valve plate 3 and the sealing block 301 are adjusted synchronously. Multiple sets of positioning rods 303 are evenly arranged on the top of the valve plate 3. The spring 304 is located on the outside of the positioning rods 303. The spring 304 applies a spring force to the valve plate 3, which can reset the sealing block 301, making it easy to close the bypass valve. Multiple sets of positioning grooves 103 are evenly arranged at the bottom end inside the slot 101. A sealing ring 302 is provided on the outside of the sealing block 301.

[0027] Please refer to this carefully. Figure 1 and Figure 2 A fixed seat 2 is provided in the middle of the slot 101. Multiple sets of fixed brackets 201 are provided on the outer side of the bottom of the fixed seat 2. Multiple sets of mounting bolts 202 are provided on the top of the fixed brackets 201. The fixed seat 2 can be installed in the slot 101 through the fixed brackets 201 and the mounting bolts 202. Multiple sets of movable holes 203 are evenly arranged inside the fixed seat 2. The movable holes 203 can be used to adjust the movement between the positioning rod 303 and the fixed seat 2, so that the valve plate 3 can move linearly and avoid the valve plate 3 from shifting. A flow hole 204 is provided in the middle of the bottom of the end cover 1 to allow the oil to flow. The top of the inner wall of the flow hole 204 is provided with a chamfered groove 205.

[0028] Please refer to this carefully. Figure 2 and Figure 3 The sealing block 301 and the valve plate 3 are integrally die-cast structures, which can keep the sealing block 301 and the valve plate 3 synchronized and seal the flow hole 204. The bottom end of the positioning rod 303 is welded to the top end of the valve plate 3 to position the valve plate 3 and prevent the valve plate 3 from shifting during use. The top end of the outer side of the sealing block 301 is provided with a fixing groove. The sealing ring 302 is detachably connected to the sealing block 301 through the fixing groove, so as to fix the sealing ring 302 on the outer side of the sealing block 301 and make the bypass valve more airtight when closed. The fixing bracket 201 is detachably connected to the end cover 1 through the mounting bolt 202 to fix the fixing bracket 201 and the end cover 1. The fixing seat 2 is detachably connected to the end cover 1 through the fixing bracket 201 and the mounting bolt 202, which facilitates the quick fixing and installation of the fixing seat 2.

[0029] Please refer to this carefully. Figure 1 and Figure 3 The top of the positioning rod 303 extends into the interior of the movable hole 203. The positioning rod 303 is movably connected to the fixed seat 2 through the movable hole 203. The movable hole 203 allows the positioning rod 303 and the fixed seat 2 to move together, achieving a positioning effect and making the movement of the valve plate 3 more stable. The fixed bracket 201 matches the positioning groove 103, achieving a limiting effect and facilitating quick positioning and installation of the fixed seat 2. The spring 304 is detachably connected to the positioning rod 303. The sealing block 204 is detachably connected to the end cover 1 through the flow hole 204, which can seal the flow hole 204 and allow the bypass valve to be opened and closed. The sealing ring 302 is detachably connected to the end cover 1 through the chamfered groove 205. The flow hole 204 is connected to the slot 101, achieving a sealing effect and making the bypass valve more airtight when closed.

[0030] Working principle: In use, the fixed bracket 201 and the positioning groove 103 engage with each other, which facilitates quick positioning of the fixed seat 2. The fixed seat 2 is fixed by the mounting bolts 202 and the fixed bracket 201. The positioning rod 303 can be moved between the fixed seat 2 through the movable hole 203, which achieves the positioning effect, causing the valve plate 3 and the sealing block 301 to move linearly. When the external temperature drops to a certain value or when the oil filter exceeds its normal service life, the automotive parts apply external force to lift the valve plate 3 and the sealing block 301, causing the sealing block 301 to separate from the flow hole 204, allowing the unfiltered oil to flow directly into the engine. When the automotive parts stop applying external force, the spring 304 applies a spring force to the valve plate 3, which can engage the sealing block 301 with the flow hole 204, and the sealing ring 302 is in close contact with the chamfered groove 205, which can tightly seal the flow hole 204.
