DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 The utility model provides the following technical solutions: an adjustable flow gas valve, comprising a valve body 1, the left side of the valve body 1 is connected to an air inlet pipe 2, and the right side of the valve body 1 is connected to an exhaust pipe 3; a threaded rod 4 is threadedly connected to the upper side of the valve body 1, an air delivery hole 5 is opened on the inner wall of the valve body 1, a spring 6 is connected to the inside of the valve body 1, a valve stem 7 is connected to the end of the spring 6, and a valve core 8 is installed at the lower end of the valve stem 7; a fixing seat 9 is bolted to the lower side of the valve body 1, a blocking block 10 is installed at the bottom of the fixing seat 9, a filter element 11 is sleeved on the outer side of the blocking block 10, and the upper end of the filter element 11 is sleeved on the protruding end inside the valve body 1;

[0028] Furthermore, the position of the threaded rod 4 and the position of the valve stem 7 are set corresponding to each other, the valve stem 7 is a "cross" shaped structure, and the valve stem 7 forms an elastic structure with the valve body 1 through the spring 6. The movement of the threaded rod 4 can be used to drive the valve stem 7, and the elastic force of the spring 6 can be used to achieve flexible movement of the valve stem 7; the position of the gas delivery hole 5 and the position of the exhaust pipe 3 are set corresponding to each other, and one end of the exhaust pipe 3 extends into the gas delivery hole 5, so that the air flow can flow smoothly from the gas delivery hole 5 into the exhaust pipe 3; the upper section of the valve core 8 is a truncated cone structure. In the initial state, the valve core 8 and the valve body 1 are engaged with each other, and the gap between the valve core 8 and the air flow channel of the valve body 1 can be gradually adjusted, thereby adjusting the gas flow;

[0029] The threaded rod 4 is rotated, and the threaded rod 4 rotates and moves on the valve body 1. When the threaded rod 4 moves downward, the valve stem 7 can be pressed to move downward, and the valve stem 7 squeezes and stores force on the spring 6. At the same time, the valve stem 7 controls the valve core 8 to move downward, gradually increasing the gap between the valve core 8 and the internal air flow channel of the valve body 1, thereby increasing the flow of gas. When the threaded rod 4 is controlled to move upward, the pressure on the valve stem 7 can be released, and the force-stored spring 6 can gradually control the valve stem 7 to move upward and reset, thereby controlling the valve core 8 to move upward, gradually reducing the gap between the valve core 8 and the internal air flow channel of the valve body 1, reducing the flow of gas, and adjusting the gas flow inside the gas valve;

[0030] Furthermore, the valve body 1 is internally rotatably connected with a limit ring 12, the outer side of the limit ring 12 is provided with a mounting ring 13, the outer side of the mounting ring 13 is connected with a fan blade 14, the lower end of the mounting ring 13 is connected with a connecting frame 15, and the lower end of the connecting frame 15 is provided with a scraper 16;

The filter element 11 is used to intercept and filter the gas, and the scraper 16 is used to scrape and clean the filter element 11; the mounting ring 13 forms a rotating structure with the valve body 1 through the limit ring 12, and the fan blades 14 are distributed at equal angles on the outside of the mounting ring 13, and the transverse center line of the fan blade 14 and the transverse center line of the intake pipe 2 are located in the same horizontal plane, so that the gas can push the fan blade 14 to rotate through the mounting ring 13, thereby controlling the scraper 16 to rotate smoothly;

[0032] The gas enters the valve body 1 from the air inlet pipe 2, and the gas pushes the fan blades 14, thereby controlling the installation ring 13 to rotate. At this time, the limit ring 12 rotates in the valve body 1 to stabilize the rotation of the installation ring 13, and the gas passes through the filter element 11, and the filter element 11 is used to intercept and filter the dust particles in the gas. At the same time, the installation ring 13 controls the rotation of the connecting frame 15, and the connecting frame 15 drives the scraper 16 installed at the end to rotate, and the scraper 16 is used to scrape and clean the filter element 11 to prevent dust from adhering to the filter element 11 and affecting the flow rate of the gas. The removed dust falls into the fixing seat 9. Later, the fixing seat 9 fixed by bolts can be removed to clean the dust. The filtered gas continues to float in the valve body 1, flows along the gap between the valve core 8 and the internal air flow channel of the valve body 1 to the gas delivery hole 5, and then is discharged from the exhaust pipe 3.
