Description

Technical Field

[0001] This utility model relates to the field of brake valve technology, specifically a multifunctional and highly adaptable brake valve. Background Technology

[0002] Brake valves are divided into air brake valves and hydraulic brake valves. The proper functioning of brake valves is crucial for parking, providing technical support for smooth braking of the vehicle. The development of this technology is of paramount importance to automobile manufacturing and road traffic safety.

[0003] However, in the operation of existing brake valves, air enters the brake valve through the intake pipe, but the air cannot be filtered to remove impurities. This can easily lead to impurities entering the brake valve, causing damage to the brake valve or blockage of the intake pipe, thus affecting the performance of the brake valve. To address these issues, the inventors have proposed a multifunctional, highly adaptable brake valve. Utility Model Content

[0004] To address the problem that during the use of a brake valve, air enters from the intake pipe but cannot be filtered, easily leading to impurities entering the brake valve and causing damage or blockage of the intake pipe, thus affecting the brake valve's performance, this utility model aims to provide a multifunctional and highly adaptable brake valve.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multifunctional and highly adaptable braking valve, comprising a valve body, a circular plate fixedly disposed within the valve body, an adjusting rod movably passing through the circular plate, a fixing ring fixedly disposed within the valve body, a sealing plate slidably disposed within the fixing ring, a conveying pipe fixedly passing through the sealing plate, the adjusting rod being able to fit against the conveying pipe, a fixing plate fixedly disposed within the valve body, the conveying pipe slidably passing through the fixing plate, and a first spring fixedly connected between the fixing plate and the sealing plate, a baffle fixedly connected between the fixing ring and the fixing plate, the two ends of the baffle being fixedly disposed within the valve body, a first through groove being formed in the fixing ring, and a second through groove being formed in the fixing plate;

[0006] The outer surface of the valve body is provided with an inlet pipe and an outlet pipe. An exhaust pipe is fixedly inserted into the bottom end of the valve body. A second protective frame is fixedly installed on one side of the inlet pipe, and an installation pipe is fixedly installed on one side of the second protective frame. A first protective frame is detachably installed at the bottom end of the second protective frame. A filter screen is fixedly installed inside the first protective frame. First, during braking, the adjusting rod moves down, causing it to approach the top of the delivery pipe. The delivery pipe is pushed by the adjusting rod to overlap with the top of the connecting pipe, thereby causing the delivery pipe to move the sealing plate down and squeeze the first spring. At the same time, the sealing plate disengages from the fixing ring. Then, the connecting pipe slides in the mounting plate and overlaps with the delivery pipe below. Simultaneously, the extension block slides down and squeezes the second spring, thereby opening the inlet valve and the outlet valve. The valve allows air to enter the valve body from the inlet pipe, then be conveyed through the gap between the fixed ring and the sealing plate, and from the first through groove to the outlet pipe. Simultaneously, it is conveyed from the second through groove to the space between the fixed plate and the mounting plate, and the conveying pipe contacts the connecting pipe. The connecting pipe then slides down to the top of the lower conveying pipe, thus enabling braking. When the braking is released, the adjusting rod resets, and the upper conveying pipe separates from the mounting plate, and the mounting plate separates from the lower conveying pipe. Compressed air from the two outlet pipes can be discharged from the exhaust pipe, thus enabling the two sets of inlet and outlet pipes to work simultaneously. When one set of inlet and outlet pipes fails, it will not affect the operation of the other set, thus making the valve body highly adaptable.

[0007] During air intake, the filter screen filters impurities in the air, preventing them from entering the valve body and causing damage to the valve body or blockage of the intake pipe. By pulling the insert rod, the insert rod drives the collar to slide in the groove and compress the third spring, causing the insert rod to disengage from the U-shaped frame. Then, the first protective frame is disassembled, which in turn allows the U-shaped frame to disengage from the second protective frame. This allows the filter screen inside the first protective frame to be disassembled and cleaned, preventing impurities from clogging the filter screen and affecting the air intake effect.

[0008] Preferably, a U-shaped frame is fixedly provided on the top surface of the first protective frame, the U-shaped frame is slidably inserted into the second protective frame, a rod is movably inserted into the second protective frame, the rod is movably inserted into the U-shaped frame, a sliding groove is provided in the second protective frame, a collar is fixedly sleeved on the outer surface of the rod, the collar is slidably disposed in the sliding groove, and a third spring is fixedly connected between the sliding groove and the collar.

[0009] Preferably, a mounting plate is fixedly provided inside the valve body, a connecting pipe slides through the mounting plate, a limiting rod is fixedly provided on the outer surface of the connecting pipe, the limiting rod slides through the mounting plate, a groove is provided in the mounting plate, the connecting pipe and the limiting rod slide in the groove, extension blocks are fixedly provided on both sides of the limiting rod, a movable rod is fixedly provided at the bottom end of the extension block, a limiting groove is provided in the mounting plate, the movable rod slides through the limiting groove, and a second spring is fixedly connected between the mounting plate and the extension block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting the first and second protective frames on one side of the air intake pipe, the filter screen can be easily installed and removed. During air intake, the filter screen can filter impurities in the air, preventing impurities from entering the valve body and causing damage to the valve body or blockage of the air intake pipe, thus not affecting the performance of the valve body.

[0012] 2. Compressed air through the two exhaust pipes can be discharged from the exhaust pipe, thus enabling the two sets of intake and exhaust pipes to work simultaneously. When one set of intake and exhaust pipes fails, it will not affect the operation of the other set, thus making the valve body highly adaptable. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-8As shown, this utility model provides a multifunctional and highly adaptable braking valve, including a valve body 1. A circular plate 21 is fixedly installed inside the valve body 1, and an adjusting rod 2 movably passes through the circular plate 21. A fixing ring 22 is fixedly installed inside the valve body 1, and a sealing plate 25 is slidably installed inside the fixing ring 22. A conveying pipe 27 is fixedly installed through the sealing plate 25, and the adjusting rod 2 can fit against the conveying pipe 27. A fixing plate 23 is fixedly installed inside the valve body 1, and the conveying pipe 27 slidably passes through the fixing plate 23. A first spring 24 is fixedly connected between the fixing plate 23 and the sealing plate 25. A baffle 26 is fixedly connected between the fixing ring 22 and the fixing plate 23, and both ends of the baffle 26 are fixedly installed inside the valve body 1. A first through groove 221 is opened in the fixing ring 22, and a second through groove 231 is opened in the fixing plate 23. When braking, the adjusting rod 2 moves down, causing the adjusting rod 2 to approach the top of the conveying pipe 27, thereby causing the conveying pipe 27 to drive the sealing plate 25 down and squeeze... Pressing the first spring 24 causes the sealing plate 25 to disengage from the fixing ring 22, thereby opening the intake valve and the exhaust valve. This allows air to enter the valve body 1 from the intake pipe 11, then be conveyed through the gap between the fixing ring 22 and the sealing plate 25, and through the first through groove 221 to the exhaust pipe 12. Simultaneously, it is conveyed through the second through groove 231 to the space between the fixing plate 23 and the mounting plate 3, causing the conveying pipe 27 to contact the connecting pipe 31. This causes the connecting pipe 31 to slide down to the top of the lower conveying pipe 27, thus enabling braking. When the braking is released, the adjusting rod 2 returns to its original position. Under the action of the first spring 24, the sealing plate 25 seals the fixing plate 23. At the same time, the adjusting rod 2 separates from the upper conveying pipe 27 and from the top of the connecting pipe 31. The bottom of the connecting pipe 31 separates from the lower conveying pipe 27, allowing the compressed air from the two exhaust pipes 12 to be discharged from the exhaust pipe 13.

[0025] The outer surface of the valve body 1 is provided with an air inlet pipe 11 and an air outlet pipe 12. An exhaust pipe 13 is fixedly inserted into the bottom end of the valve body 1. A second protective frame 42 is fixedly provided on one side of the air inlet pipe 11. An installation pipe 4 is fixedly provided on one side of the second protective frame 42. A first protective frame 41 is detachably provided at the bottom end of the second protective frame 42. A filter screen 47 is fixedly provided inside the first protective frame 41. By using the first protective frame 41 and the second protective frame 42 on one side of the air inlet pipe 11, the filter screen 47 can be easily installed and removed. Thus, when air is intake, the filter screen 47 can filter impurities in the air, preventing impurities from entering the interior of the valve body 1 and avoiding damage to the valve body 1 or blockage of the air inlet pipe 11, without affecting the performance of the valve body 1.

[0026] A U-shaped frame 43 is fixedly provided on the top surface of the first protective frame 41. The U-shaped frame 43 is slidably inserted into the second protective frame 42. A rod 44 is movably inserted into the second protective frame 42 and is movably inserted into the U-shaped frame 43. A sliding groove 421 is provided in the second protective frame 42. A collar 45 is fixedly sleeved on the outer surface of the rod 44. The collar 45 is slidably disposed in the sliding groove 421, and a third spring 46 is fixedly connected between the sliding groove 421 and the collar 45.

[0027] By adopting the above technical solution, by pulling the insertion rod 44, the insertion rod 44 drives the collar 45 to slide in the slide groove 421 and squeezes the third spring 46, thereby causing the insertion rod 44 to disengage from the U-shaped frame 43. Then, the first protective frame 41 is disassembled, thereby causing the U-shaped frame 43 to disengage from the second protective frame 42. This allows the filter screen 47 inside the first protective frame 41 to be disassembled for cleaning, preventing impurities from clogging the filter screen 47 and affecting the air intake effect.

[0028] A mounting plate 3 is fixedly installed inside the valve body 1. A connecting pipe 31 slides through the mounting plate 3. A limiting rod 32 is fixedly installed on the outer surface of the connecting pipe 31. The limiting rod 32 slides through the mounting plate 3. A groove 301 is opened in the mounting plate 3. The connecting pipe 31 and the limiting rod 32 slide in the groove 301. Extension blocks 33 are fixedly installed on both sides of the limiting rod 32. A movable rod 34 is fixedly installed at the bottom end of the extension block 33. A limiting groove 302 is opened in the mounting plate 3. The movable rod 34 slides through the limiting groove 302. A second spring 35 is fixedly connected between the mounting plate 3 and the extension block 33.

[0029] By adopting the above technical solution, during braking, the upper delivery pipe 27 is pushed by the adjusting rod 2 to overlap with the top of the connecting pipe 31. Then, the connecting pipe 31 slides in the mounting plate 3 and overlaps with the lower delivery pipe 27. At the same time, the extension block 33 slides down and squeezes the second spring 35. Then, when the brake is released, the adjusting rod 2 returns to its original position and separates the upper delivery pipe 27 from the mounting plate 3. The mounting plate 3 separates from the lower delivery pipe 27, and the compressed air from the two exhaust pipes 12 can be discharged from the exhaust pipe 13. This allows the two sets of intake pipes 11 and exhaust pipes 12 to work simultaneously. When one set of intake pipes 11 and exhaust pipes 12 fails, it will not affect the operation of the other set, thus making the valve body 1 highly adaptable.

[0030] Working principle: First, during braking, the adjusting rod 2 moves downward, causing it to approach the top of the delivery pipe 27. The delivery pipe 27 is pushed by the adjusting rod 2 to overlap with the top of the connecting pipe 31, thereby causing the delivery pipe 27 to move the sealing plate 25 downward and compress the first spring 24. At the same time, the sealing plate 25 disengages from the fixing ring 22. Then, the connecting pipe 31 slides within the mounting plate 3 and overlaps with the delivery pipe 27 below. Simultaneously, the extension block 33 slides down and compresses the second spring 35, thereby opening the intake valve and the exhaust valve. This allows air to enter the valve body 1 from the intake pipe 11, and then be delivered through the gap between the fixing ring 22 and the sealing plate 25, and through the first through groove 221 to... The air is simultaneously conveyed from the second through groove 231 to the space between the fixed plate 23 and the mounting plate 3, and the conveying pipe 27 contacts the connecting pipe 31, thereby causing the connecting pipe 31 to slide down to the top of the lower conveying pipe 27, thus enabling braking. When the braking is released, the adjusting rod 2 resets, and the upper conveying pipe 27 separates from the mounting plate 3, and the mounting plate 3 separates from the lower conveying pipe 27. The compressed air from the two air outlet pipes 12 can be discharged from the exhaust pipe 13, thereby enabling the two sets of air inlet pipes 11 and air outlet pipes 12 to work simultaneously. When one set of air inlet pipes 11 and air outlet pipes 12 fails, it will not affect the operation of the other set, thus making the valve body 1 highly adaptable.

[0031] During air intake, the filter screen 47 filters impurities in the air, preventing them from entering the valve body 1 and causing damage to the valve body 1 or blockage of the air intake pipe 11. By pulling the insert rod 44, the insert rod 44 drives the collar 45 to slide in the slide groove 421 and squeezes the third spring 46, thereby causing the insert rod 44 to disengage from the U-shaped frame 43. Then, the first protective frame 41 is disassembled, which in turn causes the U-shaped frame 43 to disengage from the second protective frame 42. This allows the filter screen 47 inside the first protective frame 41 to be disassembled and cleaned, preventing impurities from clogging the filter screen 47 and affecting the air intake effect.
