Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a novel fast exhaust valve. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN211398903U, published on September 1, 2020, which discloses a novel composite quick exhaust valve. The valve includes a main valve body with a guide rod inside. A float is slidably fitted onto the outer side of the guide rod. A main exhaust port is located at the top of the main valve body, vertically above the float. A micro-exhaust port with a micro-exhaust valve is also located at the top of the main valve body. A dustproof net is installed on the outer side of the main exhaust port. A dustproof cover is also provided on the outer side of the top of the main valve body. A centrally located tube is slidably connected to the inner side of the bottom of the main valve body. The bottom end of the centrally located tube extends to the bottom of the main valve body, and a base tube is slidably fitted onto its outer side. This invention allows for adjustment of the valve's installation height, thereby improving the valve's working efficiency. The height adjustment process is simple and quick, eliminating the time and economic costs of custom pipework. It also has a wide adjustment range and strong applicability, meeting the needs of people in production and daily life. However, this design requires manual operation, with the height adjusted via a threaded crossbar. This operation is relatively complex and time-consuming. Furthermore, the precision of manually adjusting the height of the exhaust valve is limited. Utility Model Content

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] Please see Figure 1-5 As shown, this utility model is a novel fast exhaust valve, including a base 1, a top plate 2, and an exhaust valve body 3. A lifting adjustment mechanism 4 is provided between the base 1 and the top plate 2. The lifting adjustment mechanism 4 includes two guide rods 41 fixedly connected to the top of the base 1, a fixing frame 42, two guide sleeves 43 at the bottom of the top plate 2, and a connecting block 44. A motor 45 is fixedly connected to the inner wall of the fixing frame 42. The motor 45 is a servo motor, which can accurately control the rotation angle and speed through a built-in encoder. The motor 45 is electrically connected to an external power supply and is controlled by an external program. A transition shaft 46 is rotatably connected to the front of the fixing frame 42. A first gear 47 is fixedly connected to the surface of the output shaft of the motor 45. A second gear 48 and a rotating plate 49 are fixedly connected to the surface of the transition shaft 46. A connecting arm 410 is rotatably connected to the rotating plate 49. Through the lifting adjustment mechanism 4, the height position of the exhaust valve can be quickly and accurately adjusted without manual operation, with higher precision and faster speed, saving operation time and improving work efficiency.

[0025] The top of the top plate 2 has an insertion hole 5, and a positioning rod 6 is fixedly connected to the top of the top plate 2. A quick-release installation mechanism 7 is provided between the top plate 2 and the insertion hole 5. By setting the quick-release installation mechanism 7, the exhaust valve can be quickly removed for easy maintenance and cleaning, eliminating the traditional cumbersome installation steps.

[0026] The quick-release installation mechanism 7 includes a fixing block 71 fixedly connected to the top of the top plate 2 and an insert block 72 slidably connected to the inner wall of the insertion hole 5. A spring rod 73 is fixedly connected to the right side of the fixing block 71, a latching rod 74 is fixedly connected to the right end of the spring rod 73, a pull rod 75 is fixedly connected to the left end of the latching rod 74, a pull ring 76 is fixedly connected to the left end of the pull rod 75, a fixing sleeve 77 is fixedly connected to the top of the insert block 72, a latching hole 78 is opened on the left side of the fixing sleeve 77, and a positioning sleeve 79 is fixedly connected to the right side of the fixing sleeve 77.

[0027] The exhaust valve body 3 is fixedly connected to the inner wall of the fixed sleeve 77, and the bottom of the base 1 is equipped with a caster wheel device 8.

[0028] The pull rod 75 and the fixing block 71 are slidably connected, the buckle rod 74 and the buckle hole 78 are slidably connected, the insert block 72 and the insert hole 5 are adapted to each other, and the positioning sleeve 79 and the positioning rod 6 are slidably connected.

[0029] Two guide sleeves 43 are slidably connected to adjacent guide rods 41 respectively. The first gear 47 and the second gear 48 mesh with each other. The transmission ratio between the first gear 47 and the second gear 48 is 5 to 1. The first gear 47 drives the second gear 48 to rotate, which further improves the accuracy of lifting adjustment. The connecting arm 410 and the connecting block 44 are rotatably connected.

[0030] Four caster wheels 8 are provided and arranged in a rectangular array at the bottom edge of the base 1. The caster wheels 8 can move forward in any direction. The design of multiple caster wheels 8 ensures the flexibility of the equipment, while also having a braking system to ensure stability during operation.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The working principle of this utility model is as follows: First, grasp the pull ring 76 and pull it to the left, causing the pull rod 75 to slide inside the fixing block 71, which in turn drives the latching rod 74 to move to the left against the elastic force of the spring rod 73. Then, align the positioning sleeve 79 and insert it onto the positioning rod 6, so that the insert block 72 is simultaneously inserted into the insertion hole 5, thus initially installing the exhaust valve body 3. Then, release the pull ring 76, so that the latching rod 74 is springed back to its original position by the elastic force of the spring rod 73, allowing the latching rod 74 to insert into the latching hole 78 and lock the fixing sleeve 77 to lock the exhaust. The valve body 3 is then started, and the motor 45 is started, which drives the first gear 47 to rotate through the output shaft. When the first gear 47 rotates, it drives the second gear 48 to rotate on the fixed frame 42 through the adapter shaft 46. When the adapter shaft 46 rotates, it synchronously drives the rotating plate 49 to rotate. When the rotating plate 49 rotates, it squeezes and drives the connecting block 44 through the connecting arm 410. The connecting block 44 drives the top plate 2 to slide upward through the two guide sleeves 43 on the two guide rods 41, so as to precisely adjust the height position of the top plate 2 and all its top structures, including the exhaust valve body 3.
