Description

Technical Field

[0001] The utility model relates to a breathing valve with an oil retaining component, belonging to the technical field of breathing valves. Background Art

[0002] A breathing valve is a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but can also communicate with the atmosphere (breathe) when the pressure exceeds or falls below this range. Its function is to prevent the storage tank from being damaged due to overpressure or vacuum, and at the same time reduce the evaporation loss of the stored liquid.

[0003] According to the announcement number CN219841088U, a breathing valve structure for preventing oil from overflowing is disclosed, which includes a breathing valve body, and the breathing valve body includes a cylindrical exhaust column located at the lower part thereof, and a plurality of exhaust holes connected to the inside of the breathing valve body are opened on the upper part of the side of the exhaust column. A cylindrical oil baffle seat is sleeved on the outer side of the exhaust column, and a first oil baffle plate extending inward is sealed and connected on the inner side wall of the oil baffle seat, and a gap is left between the first oil baffle plate and the exhaust column, and a second oil baffle plate extending outward is sealed and connected on the side of the exhaust column, and a gap is left between the second oil baffle plate and the oil baffle seat, and the first oil baffle plate and the second oil baffle plate are both located below the exhaust hole, and the first oil baffle plate and the second oil baffle plate are arranged at intervals from top to bottom. Air can enter the exhaust hole, but the hydraulic oil splashed in the oil tank is blocked by the first oil baffle plate and the second oil baffle plate and cannot enter the exhaust hole, so it can effectively prevent the leakage of hydraulic oil. When the above device is in use, the oil baffle plate alone cannot effectively prevent the oil from overflowing, so that the oil baffle effect of the device is not good. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A breathing valve with an oil baffle assembly comprises a pipeline, the bottom end of which is fixedly provided with a flange, a plurality of baffles are fixedly provided in an array and staggered on the lower inner wall of the pipeline, a fixing seat 1 is fixedly provided on one side of the pipeline, a fixing seat 2 is fixedly provided on the other side of the pipeline, an air outlet pipe is fixedly provided on the top end of the pipeline, the other end of the air outlet pipe extends into the fixing seat 1, an oil drop pipe is fixedly provided at the bottom end of the fixing seat 1, a one-way valve is provided in the oil drop pipe, a plug is slidably provided in the fixing seat 1, a plurality of air outlet holes are penetrated through an annular array at the top end of the fixing seat 1, and a baffle is slidably provided at the bottom end of the fixing seat 2.

[0007] Furthermore, a spring 1 is fixedly provided at the bottom end of the plug, and the bottom end of the spring 1 is fixedly connected to the inner wall of the bottom end of the fixing seat 1.

[0008] Furthermore, a protrusion matching the bottom end of the plug is provided on the lower inner wall of the fixing seat 1.

[0009] Furthermore, sealing gaskets are fixedly provided on the upper outer wall and the bottom end of the plug.

[0010] Furthermore, a sealing ring is fixedly provided around the lower part of the baffle.

[0011] Furthermore, a long tube is fixedly provided on the top of the second fixed seat, a piston is slidably provided in the long tube, a connecting rod is fixedly provided on the bottom end of the piston, the bottom end of the connecting rod extends into the second fixed seat and is fixedly connected to the top of the baffle, a spring 2 is fixedly provided on the top of the piston, and the top of the spring 2 is fixedly connected to the inner wall of the top end of the long tube.

[0012] Furthermore, a sliding rod is symmetrically inserted and slidably embedded on the baffle, and both ends of the sliding rod are fixedly connected to the inner wall of one side adjacent to the second fixing seat.

[0013] The beneficial effects of the utility model are:

[0014] The utility model is provided with a plug, an oil drop pipe and a baffle. When in use, when high pressure appears in the pipeline, the baffle can block the oil to a certain extent, thereby preventing more oil from entering the air outlet pipe with the high-pressure gas. When the high-pressure gas enters the fixed seat one through the air outlet pipe, it will push the plug to move downward. At this time, the plug will squeeze the spring one. By providing a protrusion, the bottom end of the plug will conflict with the top end of the protrusion, thereby preventing the oil from falling onto the inner wall of the bottom end of the fixed seat one. At the same time, the high-pressure gas will be discharged through the air outlet hole, and the oil will fall into the space of the fixed seat one. When there is no high pressure in the device, the spring one will push the plug to reset, thereby causing the oil to fall onto the inner wall of the bottom end of the fixed seat one. When there is a lot of oil, the oil will fall back into the oil tank through the one-way valve. The utility model can effectively prevent oil from overflowing, thereby improving the oil blocking effect of the device and further improving the practicability of the device.

[0023] A breathing valve with an oil baffle assembly comprises a pipeline 1, a flange 2 is fixedly provided at the bottom end of the pipeline 1, a plurality of baffles 3 are staggeredly fixed in an array on the lower inner wall of the pipeline 1, a fixing seat 1 4 is fixedly provided on one side of the pipeline 1, a fixing seat 2 5 is fixedly provided on the other side of the pipeline 1, an air outlet pipe 6 is fixedly provided at the top end of the pipeline 1, the other end of the air outlet pipe 6 extends into the fixing seat 1 4, an oil drop pipe 7 is fixedly provided at the bottom end of the fixing seat 1 4, a one-way valve 8 is provided in the oil drop pipe 7, a plug 9 is slidably provided in the fixing seat 1 4, a plurality of air outlet holes 10 are opened through the top annular array of the fixing seat 1 4, and a baffle 11 is slidably provided at the bottom end of the fixing seat 2 5.

[0024] Specifically, Figure 1-Figure 4As shown, a spring 12 is fixedly provided at the bottom end of the plug 9, and the bottom end of the spring 12 is fixedly connected to the bottom inner wall of the fixing seat 4. A protrusion matching the bottom end of the plug 9 is provided on the lower inner wall of the fixing seat 4. When the high-pressure gas pushes the plug 9 to move downward, the plug 9 will squeeze the spring 12. By setting the protrusion, the bottom end of the plug 9 will collide with the top end of the protrusion, thereby preventing the oil from falling onto the bottom inner wall of the fixing seat 4.

[0025] Specifically, Figure 1-Figure 4 As shown, sealing gaskets are fixedly provided on the upper outer wall and the bottom end of the plug 9, and a sealing ring is fixedly provided around the lower part of the baffle 11. By arranging the sealing gasket and the sealing ring, the sealing performance of the device can be improved.

[0026] Specifically, Figure 1-Figure 4 As shown, a long tube 13 is fixedly provided at the top of the fixed seat 2 5, a piston 14 is slidably provided in the long tube 13, a connecting rod 15 is fixedly provided at the bottom end of the piston 14, the bottom end of the connecting rod 15 extends into the fixed seat 2 5 and is fixedly connected to the top of the baffle 11, a spring 2 16 is fixedly provided at the top of the piston 14, the top of the spring 2 16 is fixedly connected to the inner wall of the top end of the long tube 13, when negative pressure appears in the device, the outside air will push the baffle 11 to move upward, and the baffle 11 will push the piston 14 upward through the connecting rod 15 to squeeze the spring 2 16, so that air can enter the pipeline 1 through the fixed seat 2 5.

[0027] Example 2 Please refer to Figure 1-Figure 4 The difference between this embodiment and embodiment 1 is that a slide rod 17 is symmetrically inserted and slidably embedded on the baffle 11, and both ends of the slide rod 17 are fixedly connected to the inner wall of one side adjacent to the fixing seat 2 5. By setting the slide rod 17, when the baffle 11 moves, the slide rod 17 can support the baffle 11.

[0028] Working principle of the utility model: during use, when high pressure appears in the pipeline 1, the baffle 3 can block the oil to a certain extent, thereby preventing more oil from entering the air outlet pipe 6 along with the high-pressure gas. When the high-pressure gas enters the fixed seat 4 through the air outlet pipe 6, it will push the plug 9 to move downward. At this time, the plug 9 will squeeze the spring 12. By setting a protrusion, the bottom end of the plug 9 will conflict with the top end of the protrusion, thereby preventing the oil from falling onto the inner wall of the bottom end of the fixed seat 4. At the same time, the high-pressure gas will be discharged through the air outlet 10, and the oil will fall into the air of the fixed seat 4. When there is no high pressure in the device, the spring 12 will push the plug 9 to reset, so that the oil will fall to the inner wall of the bottom end of the fixed seat 4. When there is more oil, the oil will fall back into the oil tank through the one-way valve 8. When negative pressure appears in the device, the outside air will push the baffle 11 to move upward. At this time, the baffle 11 will push the piston 14 upward through the connecting rod 15 to squeeze the spring 2 16, so that the air can enter the pipeline 1 through the fixed seat 2 5. By setting the sliding rod 17, when the baffle 11 moves, the sliding rod 17 can support the baffle 11.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
