[0025] The filter assembly 5 includes a filter ball 501 installed inside the spherical connecting shell 1. The outer wall of the filter ball 501 is in close contact with the inner wall of the spherical connecting shell 1. Filter holes 503 are evenly provided on the filter ball 501. An end groove 502 is provided on the side of the filter ball 501 close to the intake pipe 2. The back of the filter ball 501 is fixedly connected to the output shaft of the motor 504. The motor 504 is fixedly installed on the back shell of the spherical connecting shell 1. When the end groove 502 on the filter ball 501 faces the intake pipe 2, the gas enters the exhaust pipe 3 from the intake pipe 2. The gas enters the filter ball 501 through the end groove 502 and is then discharged from the filter hole 503. When passing through the filter hole 503, the gas is filtered and impurities are removed, reducing the adhesion of impurities on the valve body and the inner wall of the pipe, improving the corrosion resistance, and the impurities can be stored inside the filter ball 501 for convenient centralized processing.

[0026] The pressure reducing assembly 6 includes a fixed cylinder 602 which is sleeved and installed on the top of the pressure reducing tube 4, and side cylinders 603 are symmetrically installed on both sides of the fixed cylinder 602. A clamping rod 604 is movably installed inside the side cylinder 603, and one end of the clamping rod 604 is clamped into the inside of the clamping groove 601. The clamping groove 601 is symmetrically arranged on the side wall of the pressure reducing tube 4. A first spring 605 is installed on the end of the clamping rod 604 away from the pressure reducing tube 4. One end of the first spring 605 is fixedly connected to the inner wall of the end of the side cylinder 603 away from the fixed cylinder 602. A pull rod 606 is installed on the end of the clamping rod 604 close to the first spring 605. The pull rod 606 passes through the outside of the side cylinder 603, and a top cylinder 607 is installed on the top of the fixed cylinder 602. The top cylinder 607 is connected to the fixed cylinder 602, and exhaust holes 608 are provided at equal angles on the outside of the top cylinder 607. A stopper 610 is dynamically installed, and the outer wall of the stopper 610 is tightly attached to the inner wall of the top tube 607. The stopper 610 is located below the exhaust hole 608. A second spring 611 is installed on the top of the stopper 610. The top of the second spring 611 is fixedly connected to the inner top wall of the top tube 607. A limiting ring 609 is fixedly installed on the inner wall of the top tube 607. The top wall of the limiting ring 609 contacts the bottom wall of the stopper 610. Under the limiting action of the limiting ring 609, the second spring 611 is in a compressed state. The motor 504 drives the filter ball 501 to rotate ninety degrees clockwise so that the end groove 502 corresponds to the pressure reducing tube 4, and then the clamping rod 604 is disengaged from the clamping groove 601, the fixed tube 602 is removed from the top of the pressure reducing tube 4, and then the inside of the filter ball 501 is cleaned from the pressure reducing tube 4 and the end groove 502, which is convenient for cleaning.

[0027] Working principle: During operation, when the gas moves from the intake pipe 2 through the spherical connecting shell 1 toward the inside of the exhaust pipe 3, the gas enters the filter ball 501 from the end groove 502, and then enters the exhaust pipe 3 from the filter hole 503. When passing through the filter hole 503, the gas is filtered, so that impurities remain in the filter ball 501, thereby facilitating the collection of impurities and reducing impurities adhering to the inner wall of the valve body, thereby improving the corrosion resistance of the valve body and pipeline;

[0028] When the air pressure is high, the air pressure inside the pressure reducing tube 4 increases, pushing the stopper 610 to overcome the elastic force of the second spring 611 and move upward, so that the stopper 610 moves above the exhaust hole 608, allowing the gas to be discharged from the exhaust hole 608, thereby achieving a pressure relief effect and protecting the valve body;

[0029] When there are many impurities inside the filter ball 501 and it needs to be cleaned, turn on the motor 504 so that the output shaft of the motor 504 drives the filter ball 501 to rotate ninety degrees clockwise, so that the end groove 502 corresponds to the pressure reducing tube 4, and then pull the clamping rod 604 outward through the pull rod 606, so that the clamping rod 604 is disengaged from the clamping groove 601, thereby removing the fixing tube 602, and then use tweezers, brushes and other cleaning tools from the pressure reducing tube 4 through the end groove 502 to enter the filter ball 501, and deal with the impurities in the filter ball 501 to facilitate cleaning.

Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
