Description

Technical Field

[0001] The invention relates to the field of valve testing equipment, and more particularly to a vehicle oil pump valve testing device. Background Art

[0002] An automobile one-way valve is a valve that only allows oil to flow in the forward direction but not in the reverse direction, so it is also called a non-return valve or a check valve. It is divided into two structures: straight-through type and right-angle type according to the flow direction of the inlet and outlet oil. The sealing performance of the one-way valve needs to be tested before it leaves the factory.

[0003] For example, a Chinese patent with the authorization announcement number CN211527739U discloses a one-way valve air tightness detection device, which injects air into the output end of the one-way valve and observes whether the pressure on the pressure gauge increases. If the pressure does not change, it means that the one-way valve has good air tightness, and if the pressure increases, it means that the one-way valve has poor air tightness, which is convenient for employees to detect the air tightness of the one-way valve, improves detection efficiency, and improves practicality; However, before injecting gas, the inflation head and the connecting pipe need to be connected to the two ends of the one-way valve respectively. During the connection process, the one-way valve cannot maintain a vertical state with the ground, and there is a certain inclination, which will cause a certain gap between the one-way valve and the inflation head and the connecting pipe, thereby causing the pressure at the connection of the one-way valve to be low. When the pressure during gas injection is greater than the pressure at the connection, gas leakage will occur at the connection; this will cause problems with the sealing of the one-way valve, and the pressure gauge value will remain unchanged, making it impossible to detect whether the sealing of the one-way valve is intact, and it is impossible to observe whether there is a gas leak in a timely and intuitive manner.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 , an automobile oil pump valve testing device, comprising a water tank 1, a support frame 2 is fixedly connected to both sides of the water tank 1, a water tank 3 is fixedly connected to one side of the upper surface of the support frame 2, a sealing component 4 for sealing the connection of the one-way valve is arranged at the bottom of the water tank 1, and a pumping component 5 for purification is arranged at one side of the bottom of the water tank 1; like Figure 2 and Figure 3 As shown, the sealing assembly 4 includes a fixed ring 41 fixed to the bottom of the water tank 1, a switching assembly 44 fixed to one side of the inner surface of the water tank 1 and a shifting assembly 45 fixed to the middle of the bottom of the water tank 1, one side of the outer surface of the fixed ring 41 is rotatably connected to a rotating ring 42, an oblique through groove 47 is provided inside the rotating ring 42, a telescopic rod 49 is slidably connected to the inside of the fixed ring 41, one side of the telescopic rod 49 is fixedly connected to an arc clamping block 46, one side of the telescopic rod 49 is fixedly connected to a protrusion 48, and one side of the rotating ring 42 is rotatably connected to a locking screw 43.

[0023] Four groups of oblique through grooves 47 are provided, one side of the protrusion 48 passes through the interior of the oblique through groove 47, the protrusion 48 and the oblique through groove 47 slide with each other, the arc clamping block 46 is located inside the fixed ring 41, one side of the rotating ring 42 is fixedly connected with an internal thread plate, the locking screw 43 passes through the interior of the internal thread plate and is connected by threads, and a handle is symmetrically fixedly connected to the side of the rotating ring 42 away from the locking screw 43.

[0024] When testing the one-way valve, the one-way valve of the automobile oil pump is fixed by the transposition component 45, and one end of the one-way valve is located inside the fixed ring 41. In order to ensure the rigor of the experiment, it is necessary to seal the connection between the one-way valve and the experimental pipeline. At this time, rotating the rotating ring 42 drives the four oblique grooves 47 to rotate, and the oblique grooves 47 drive the protrusions 48 inside it to move. The protrusions 48 drive the telescopic rod 49 to approach the center of the fixed ring 41, and the four arc-shaped clamping blocks 46 approach the center synchronously. The four arc-shaped clamping blocks 46 squeeze the connection of the one-way valve, which can ensure that the connection between the pipeline and the one-way valve is squeezed, increase the squeezing force at the connection between the one-way valve and the pipeline, and increase the upper limit of the pressure inside the one-way valve. Leakage is effectively prevented when the one-way valve is subjected to a sealing experiment, thereby avoiding affecting the authenticity of the experimental data.

[0025] like Figure 4 and Figure 5 As shown, the switching assembly 44 includes a circular frame 441 fixed to one side of the inner surface of the water storage tank 1 and a fixing plate 4412 fixed to one side of the bottom of the water storage tank 1, the second guide tube 445 and the third guide tube 448 are respectively connected through the top edge of the circular frame 441, a rotating shaft 449 is passed through and rotatably connected to the middle of the top of the circular frame 441, a circular rubber block 4410 is rotatably connected to the bottom of the rotating shaft 449, a through hole 4411 is provided inside the circular rubber block 4410, one side of the second guide tube 445 is connected to the first water pump 446, one side of the third guide tube 448 is connected to the air pump 447, and a connecting component is provided on the lower surface of the circular frame 441.

[0026] The connecting component includes a fixing plate 4412 fixed to one side of the bottom of the water storage tank 1, a first flow guide pipe 442 is connected to the inside of the fixing plate 4412, one side of the first flow guide pipe 442 is connected to a rubber hose 443, one side of the rubber hose 443 is connected to a connecting sleeve 444, the top of the first flow guide pipe 442 extends to the inside of the circular frame 441, a pointer is provided on the upper surface of the rotating shaft 449, and the direction of the pointer points to the through hole 4411, the input end of the first water pump 446 extends to the inside of the water tank 3, the upper surface of the circular rubber block 4410 is tightly fitted with the top of the circular frame 441, the lower surface of the circular frame 441 is a truncated cone, the inner side of the shaped connecting sleeve 444 contains a pressure sensor, and the pressure sensor is connected to the terminal through a signal.

[0027] When conducting a sealing experiment on the one-way valve, it is necessary to test the sealing performance of the one-way valve under different media, but different pipes need to be replaced to connect with the one-way valve, which results in many testing steps, heavy workload, and reduced work efficiency. For this reason, before the test, water containing pigment is poured into the water tank 3, with the output end of the one-way valve facing the connecting sleeve 444, and the connecting sleeve 444 is put on the output end of the one-way valve. When liquid is introduced into the one-way valve, the rotating shaft 449 is rotated to drive the circular rubber block 4410 to rotate, and the through hole 4411 is turned to the bottom of the second guide tube 445, so that the interior of the second guide tube 445 is connected to the interior of the circular frame 441, and then the first guide tube 445 is opened. A water pump 446 delivers the liquid in the water tank 3 to the second flow guide pipe 445, and flows to the connection between the one-way valve and the connecting sleeve 444 through the through hole 4411, the first flow guide pipe 442 and the rubber hose 443. The gas in the rubber hose 443 flows to the inside of the circular frame 441. As the first water pump 446 continuously delivers water to the second flow guide pipe 445, the pressure at the connection between the connecting sleeve 444 and the one-way valve increases continuously. Before the pressure reaches the specified one-way valve bearing pressure, observe whether there is colored water flowing out from the other end of the one-way valve. If there is colored water flowing out, it indicates that the sealing of the one-way valve is poor and unqualified. When it is necessary to introduce gas into the one-way valve, rotate the rotating shaft 449 to drive the through hole 4411 to rotate to the bottom of the third guide tube 448, remove the connecting sleeve 444 from the outside of the one-way valve, drain the water in the rubber hose 443, and then put the connecting sleeve 444 on the one-way valve, turn on the air pump 447, and the air will flow to the one-way valve through the third guide tube 448, the through hole 4411, the first guide tube 442 and the rubber hose 443. Observe whether there is air bubble leakage on one side of the one-way valve. Leakage indicates that the one-way valve has poor sealing. Therefore, the second guide tube 445 and the third guide tube 448 can be switched by rotating the rotating shaft 449 to drive the circular rubber block 4410 to rotate. Switching between different media can reduce the switching of all equipment and pipelines in the entire process, greatly reduce the workload, and improve work efficiency.

[0028] like Figure 6 As shown, the shifting component 45 includes a slide groove 451 opened at the bottom of the water tank 1, the interior of the slide groove 451 is slidably connected with a fixed column 452, the outer surface of the fixed column 452 is rotatably connected with a fixed frame 458, and the two sides of the fixed frame 458 are slidably connected with pull rods 455, and the sides of the two pull rods 455 close to each other are respectively fixedly connected with clamping sleeves 456, and the outer surfaces of the two clamping sleeves 456 are fixedly connected with inclined plates 459, the outer surface of the pull rod 455 is sleeved with a spring 457, the outer surface of the fixed column 452 is symmetrically provided with a socket 453, and one side of the fixed frame 458 is slidably connected with an insertion rod 454.

[0029] A slider is slidably connected inside the slide groove 451 , a fixing column 452 is fixed on the upper surface of the slider, the insertion rod 454 and the insertion hole 453 are adapted to each other, and the spring 457 is located between the clamping sleeve 456 and the fixing frame 458 .

[0030] After the sealing test of the output end of the one-way valve is completed, it is also necessary to test the sealing of the inside of the one-way valve when it is closed. Generally, the one-way valve needs to be removed from the transposition assembly 45 and then flipped and switched, which will increase the operation steps. At this time, the plug rod 454 is pulled out from the inside of the socket 453 to release the fixed state between the fixing frame 458 and the fixing column 452, and the fixing frame 458 and the fixing column 452 are pulled to slide inside the slide groove 451 to move the one-way valve out from the inside of the fixing ring 41, and then the fixing frame is rotated. 458 drives the one-way valve to rotate one hundred and eighty degrees, and then pushes the fixing frame 458 to drive the one-way valve to move toward the inside of the fixing ring 41, and squeezes the connection between the one-way valve and the connecting sleeve 444 through the arc-shaped clamping block 46, closes the one-way valve and injects gas into the one-way valve, and observes whether there is gas leakage at the output end of the one-way valve. Therefore, when the sealing of different ends of the one-way valve is tested, the connection end of the one-way valve with the connecting sleeve 444 can be quickly replaced, reducing the steps of removing the one-way valve from between the two clamping sleeves 456, thereby improving efficiency.

[0031] like Figure 7 As shown, the pumping assembly 5 includes a second water pump 53 fixed at the bottom edge of the water storage tank 1, and a purification assembly 54 is provided at the input end of the second water pump 53. The purification assembly 54 is connected to an arc-shaped hollow plate 51, and a side hollow plate 55 is symmetrically connected to one side of the arc-shaped hollow plate 51. A plurality of second water inlet holes 56 are evenly opened on the side where the two side hollow plates 55 are close to each other, and a first water inlet hole 52 is opened on the inner surface of the arc-shaped hollow plate 51.

[0032] The insides of the side hollow plates 55 and the arc-shaped hollow plates 51 are interconnected, and the transposition assembly 45 is located between the two side hollow plates 55 .

[0033] During the test, if the pigmented water leaks when the one-way valve is tested for sealing, the entire water inside the water storage tank 1 will be polluted. As the pigment concentration in the water increases, it will be impossible to visually observe whether there is water leakage in the one-way valve during subsequent observations, which will cause deviations in the test results. Therefore, during the test, when the pigmented water leaks from the one-way valve, the second water pump 53 is opened in time, and the second water pump 53 pumps water into the arc hollow plate 51 and the side hollow plate 55 through the purification component 54. The water inside the side hollow plate 55 and the arc hollow plate 51 flows, and the water at the first water inlet hole 52 and the second water inlet hole 56 is sucked into the interior of the arc hollow plate 51. When the pigmented water diffuses to the second water inlet hole 56 and the first water inlet hole 52, it is promptly sucked into the interior of the arc hollow plate 51 and discharged, thereby preventing the pigmented water from diffusing and reducing the concentration of the pigment in the water to avoid a direct impact of excessive concentration on subsequent observations.

[0034] like Figure 8 As shown, the purification component 54 includes a first connecting cylinder 541 fixed on one side of the arc-shaped hollow plate 51 and a second connecting cylinder 547 fixed on the input end of the second water pump 53. The outer surface of the first connecting cylinder 541 is sleeved with a movable cylinder 542, and the middle of the outer surface of the second connecting cylinder 547 is fixedly connected with a second limiting ring 546, and one side of the outer surface of the second connecting cylinder 547 is sleeved with a replacement sleeve 545, the outer surface of the replacement sleeve 545 is fixedly connected with the first limiting ring 544, and the inner surface of the replacement sleeve 545 is fixedly connected to the reverse osmosis membrane 543.

[0035] The inner surfaces of the movable cylinder 542 and the replacement sleeve 545 are provided with rubber sleeves, the first connecting cylinder 541 and the interior of the arc hollow plate 51 are interconnected, and the other end of the first limiting ring 544 is sleeved on the outer surface of the replacement sleeve 545 .

[0036] The water containing the pigment is sucked away through the first water inlet hole 52 and the second water inlet hole 56 and discharged in time. However, the direct discharge of the water containing the pigment will result in a waste of water resources. A large amount of water resources will be used during the detection, resulting in an increase in the cost of the detection. Therefore, when the water containing the pigment enters the interior of the arc hollow plate 51, it will enter the interior of the first connecting cylinder 541 and flow toward the reverse osmosis membrane 543 through the interior of the first connecting cylinder 541. When the water containing the pigment passes through the reverse osmosis membrane 543, the small pigment particles in the water are blocked and filtered by the reverse osmosis membrane 543, and the water is filtered and purified. The purified water can be recycled to reduce the use of water resources. After a period of time, the reverse osmosis membrane 543 needs to be replaced or cleaned. The movable cylinder 542 is pushed to the side away from the replacement sleeve 545 and leaves the outer surface of the replacement sleeve 545. The replacement sleeve 545 is then removed from the outer surface of the second connecting cylinder 547, so that the reverse osmosis membrane 543 can be cleaned or replaced, thereby improving the filtering effect and rate of the reverse osmosis membrane 543.

[0037] Instructions for use: First, add a certain amount of water to the water tank 1, add water containing pigment to the water tank 3, pull the two pull rods 455 away from each other, place the one-way valve between the two clamping sleeves 456, clamp the one-way valve with the spring 457, push the fixing frame 458 to drive the one-way valve to move inside the fixing ring 41, insert the insertion rod 454 into the inside of the insertion hole 453, rotate the rotating ring 42, and drive the protrusion 48 to drive the telescopic rod 49 to approach the center of the fixing ring 41 through transmission, and the four arc-shaped clamping blocks 46 move toward the center synchronously, and the four arc-shaped clamping blocks 46 move toward the center. The block 46 squeezes the connection of the one-way valve, which can ensure that the connection between the pipeline and the one-way valve is squeezed, increase the squeezing force of the connection between the one-way valve and the pipeline, and increase the upper limit of the pressure inside the one-way valve, effectively preventing leakage when the one-way valve is subjected to a sealing test, thereby affecting the authenticity of the experimental data. The rotating shaft 449 drives the circular rubber block 4410 to rotate, so as to switch the second guide tube 445 and the third guide tube 448 for use, and switch the use of different media, thereby reducing the switching of all equipment and pipelines in the entire process, greatly reducing the workload and improving work efficiency. Then, if the water containing the pigment leaks and spreads, when the water containing the pigment diffuses to the second water inlet hole 56 and the first water inlet hole 52, it is promptly sucked into the interior of the arc hollow plate 51 and discharged, thereby preventing the water containing the pigment from diffusing and reducing the concentration of the pigment in the water to avoid a direct impact of excessive concentration on subsequent observations. At the same time, the reverse osmosis membrane 543 filters the water, filters the pigment particles in the water, and the water can be recycled.

[0038] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
