Description

Technical Field

[0001] This invention relates to the field of clearance adjustment technology, and specifically to a leak-free clearance adjustment device. Background Technology

[0002] When the compressor is working, after the piston reaches top dead center, there will always be a part of high-pressure gas remaining in the cylinder (located in the clearance volume). When the piston moves down to enter the intake stroke, this part of the residual gas will first expand and depressurize. Only when the pressure in the cylinder is lower than the pressure in the intake pipe will the intake valve open and fresh gas begin to be drawn in. The larger the volume occupied by the residual gas after expansion, the smaller the effective volume of fresh gas that can be drawn in the cylinder, and the lower the final exhaust volume. The smaller the volume occupied by the residual gas after expansion, the larger the effective intake volume of the cylinder, and the higher the exhaust volume. Energy consumption can be optimized by adjusting the clearance. The existing clearance adjustment device has friction between the ball core and the sealing seat when it is opened and closed. The entire device only achieves sealing by contact between the ball core and the sealing seat. After long-term use, the device will leak. Not only will it fail to achieve the effect of adjusting clearance, but it will also cause abnormal energy consumption of the compressor. Therefore, it is necessary to invent a leak-free clearance adjustment device. Summary of the Invention

Boxes 14 are fixedly embedded in the top and bottom of the outer shell 4, and both boxes 14 are fixedly connected to the inner wall of one side of the outer shell 4. Pipes 15 are fixedly connected between each of the two boxes 14 and the two annular air cushions 13, and both pipes 15 penetrate the outer shell 4, the housing 1, and the sealing seat 3 and are fixedly connected to them.

Spring 19 is provided inside the two boxes 14 respectively, and the two ends of spring 19 are fixedly connected to piston 16 and inner wall of box 14 respectively. Guide pins 20 are fixedly connected to one side of the two boxes 14. The two guide pins 20 pass through the moving plate 11 and slide in contact with it. Spring 21 is fixedly connected between the moving plate 11 and the protrusions of the two guide pins 20 respectively. The two springs 21 are respectively sleeved on the outside of the two guide pins 20. In this embodiment, a sealing component is designed so that when in use, the two annular air cushions 13 can wrap around the ball core 2, thus achieving resealing. When the sealing seat 3 and the ball core 2 are in conjunction, a double seal can be achieved. In this way, even if there is a large wear between the sealing seat 3 and the ball core 2 during use, the entire device will not leak, thus achieving a leak-free system.

Support blocks 23 are fixedly connected to the inner walls of both the front and rear sides of the outer casing 4. Two rotating shafts 24 are connected to one side of each support block 23.

The auxiliary component can restrict the turntable 22 and the rotating rod 5 to prevent the ball core 2 from rotating freely. To achieve the purpose of controlling the operation of the components, the device adopts the following technical solution: The moving component includes two grooves, which are respectively opened at the top and bottom of the rotating shaft 9. The top and bottom of the rotating shaft 9 are provided with connecting rods 28. Two support rods 29 are sleeved on the outside of the two connecting rods 28. The four support rods 29 are fixedly connected to the rotating block 8. Gears 30 are fixedly sleeved on the outside of the two connecting rods 28. The inner side of the two gears 30 is provided with toothed plates 31 that mesh with them. The two toothed plates 31 are fixedly connected in the two grooves. A lever 32 is fixedly sleeved on the outside of the two connecting rods 28. A magnet 33 is fixedly connected to the two levers 32. Two pads 34 are fixedly connected to one side of the outer shell 4. The two pads 34 are in contact with the two levers 32 respectively. The design of the moving component can not only control the operation of the sealing component and the auxiliary component, but also control the rotation of the ball core 2. To reduce wear, the device employs the following technical solution: the rotating rod 5 is connected to the housing 1 via a sealed bearing; the rotating block 8 is connected to the outer shell 4 via a bearing; the moving plate 11 is connected to the rotating shaft 9 via a bearing; the rotating shaft 24 is connected to the support block 23 and the outer shell 4 via a bearing; and the connecting rod 28 is connected to the support rod 29 via a bearing. The bearing connection reduces wear.

[0020] The usage process of this invention is as follows: Under the action of the connecting pipe 7, this device can be installed on the cylinder of the compressor. Since the connecting pipe 7 has threads, the device can be directly screwed onto the cylinder during use. When it is necessary to adjust the clearance, insert the gas supply pipe into the air pipe 6. Then, move the two levers 32 to make the two levers 32 come together, so that the two magnets 33 can be attracted together. When the two levers 32 come together, the two connecting rods 28 and the two gears 30 can rotate. The rotation of the two gears 30 drives the two tooth plates 31 to move to the right. The movement of the tooth plates 31 can make the rotating shaft 9 and the moving plate 11 move to the right. When the movable plate 11 moves to the right, it can pull the two ropes 17, which can make the two pistons 16 move towards the middle. Then, under the action of the two pipes 15, the air in the two annular air cushions 13 can be sucked into the two boxes 14. At the same time, the two springs 19 are compressed. After the air is sucked away, the two annular air cushions 13 will collapse and no longer contact the ball core 2. Since the spirals 27 on the two rotating shafts 24 pass through the movable plate 11, when the movable plate 11 moves to the right under the action of the spirals 27, it can make the two rotating shafts 24 rotate. The rotation of the two rotating shafts 24 drives the two levers 26 to open outward and no longer contact the turntable 22. The rotation of the two rotating shafts 24 can also cause the two torsion springs 25 to undergo elastic deformation. When the annular air cushion 13 collapses and the locking rod 26 is no longer in contact with the turntable 22, rotating the two levers 32 will cause the connecting rod 28, gear 30, support rod 29, rotating block 8, rotating shaft 9 and other components to rotate. The rotation of rotating shaft 9 will drive the prism block 10 to rotate, and the rotation of prism block 10 will drive the rotating rod 5 to rotate. The rotation of rotating rod 5 will cause the ball core 2 to rotate. The rotation of ball core 2 will open the channel inside the housing 1. Then, under the action of the air supply pipe, air can be introduced into the air pipe 6 and the housing 1. The air can then enter the cylinder through the housing 1, thus achieving clearance adjustment. After the adjustment is completed, rotating the two levers 32 again will cause the ball core 2 to rotate again. In this way, the ball core 2 and the sealing seat 3 will come together, thereby sealing the housing 1 and preventing the introduced air from leaking. After the ball core 2 and the sealing seat 3 are joined together, the two levers 32 are turned, and then the two gears 30 rotate again, which can move the rotating shaft 9, the moving plate 11 and other components to the left to reset. At the same time as the reset, under the action of the spring 19, the two pistons 16 can move outward, so that the air in the two housings 14 can enter the two annular air cushions 13 through the pipe 15. In this way, the two annular air cushions 13 can be inflated, so that the two annular air cushions 13 can wrap around the two ball cores 2, thereby achieving resealing. With the cooperation of the sealing seat 3 and the ball core 2, a double seal can be achieved. In this way, even if there is a large wear between the sealing seat 3 and the ball core 2 during use, the entire device will not leak, thus achieving zero leakage. After the clearance is adjusted, not only can the clearance be prevented from changing, but also the abnormal energy consumption of the compressor can be prevented. When the movable plate 11 is reset, the two rotating shafts 24 can be reversed, so that the two locking rods 26 will contact the turntable 22 again, thereby squeezing and restricting the turntable 22 and the rotating rod 5. After the clearance is adjusted, the ball core 2 can be prevented from rotating randomly. This can prevent the ball core 2 from rotating and changing the clearance due to accidental contact during daily use, thus improving safety. Since there are small protrusions on the locking rods 26 and the turntable 22, the restriction effect is better and the safety is also better. When in use, the two levers 32 must be brought together to deflate the annular air cushion 13 and release the restriction on the turntable 22 before the ball core 2 can rotate. Otherwise, it cannot rotate. This device can not only prevent the ball core 2 from rotating due to accidental contact, but also prevent the ball core 2 from rotating due to high pressure in the clearance.

[0021] The above are merely preferred embodiments of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
