[0002] During use, in many industrial and engineering applications, the gas flow rate needs to be precisely controlled to ensure the stability and consistency of the production process. By effectively adjusting the gas flow rate, excessive use of gas can be avoided, thereby saving energy and reducing costs. Therefore, a gas control device is particularly needed.

[0003] However, most of the existing gas control devices usually use proportional valves to adjust the gas flow during use. When using proportional valves, a single proportional valve may be subjected to a large gas pressure, which reduces the service life. In addition, if a single proportional valve fails, it may cause the entire system to fail, increasing the cost of maintenance and downtime. Utility Model Content

[0004] The purpose of the utility model is to provide a gas control device to solve the problem that the existing gas control device proposed in the above background technology usually uses a proportional valve to adjust the gas flow during use.

If a single proportional valve fails, it may cause the entire system to fail, increasing the cost of maintenance and downtime.

DETAILED DESCRIPTION

[0018] 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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0019] See also Figure 1-4 The utility model provides an air control device: comprising a flange 1 and an air control mechanism 2, wherein the air control mechanism 2 is arranged at one end of the flange 1, and the mounting mechanism 3 is arranged at the other end of the flange 1.

[0020] Furthermore, the gas control mechanism 2 includes a cache box 201, a pressure sensor 202, a feedback circuit 203, a solenoid valve 204 and a manual valve 205. One end of the flange 1 is fixedly connected to the cache box 201, the inner surface of the cache box 201 is fixedly connected to the pressure sensor 202, the outer surface of the pressure sensor 202 is electrically connected to the feedback circuit 203, the outer surface of the cache box 201 is fixedly connected to the solenoid valve 204, and one end of the cache box 201 is fixedly connected to the manual valve 205. Through the arrangement of the cache box 201, the pressure sensor 202, the feedback circuit 203, the solenoid valve 204 and the manual valve 205, during use, after the device is installed through the installation mechanism 3, the gas will first enter the cache box 201 from the end of the cache box 201 with a single groove. The cache box 201 has a certain cache space. Six slots are provided at the other end of the box 201 to connect six solenoid valves 204 to divert the gas. The input end of the solenoid valve 204 is connected to one end of the six slots of another cache box 201, and the gas is gathered to one output. Each solenoid valve 204 can be independently controlled. The internal pressure of the two cache boxes 201 is detected by the pressure sensor 202 in the cache box 201, and the opening and closing of the solenoid valve 204 is calculated and controlled by the feedback circuit 203. When the pressure in the front is too high, more solenoid valves 204 are opened to disperse the pressure received by a single solenoid valve 204. When the pressure is too low, some solenoid valves 204 are closed to increase the gas flow rate. The output end of the gas is connected to a manual valve 205 to manually control the passage of the gas. Through the setting of the gas control mechanism 2, the gas pressure is dispersed to multiple solenoid valves 204, and can be controlled individually, so as to facilitate the adjustment of the gas flow.

[0021] Furthermore, an input slot is provided at one end of the cache box 201, and six output slots distributed in a ring are provided at the other end of the cache box 201. The number of cache boxes 201 is two and they are symmetrically distributed. The six slots provided in the cache box 201 are connected to six solenoid valves 204 to divert the gas. The input end of the solenoid valve 204 is connected to one end of the six slots of another cache box 201, and the gas is then gathered to one place for output.

[0022] Furthermore, the number of the solenoid valves 204 is six and they are distributed in a ring shape. The output slots of the two cache boxes 201 are fixedly connected to the input end and the output end of the solenoid valve 204 respectively, so that the gas pressure is dispersed to multiple solenoid valves 204, and they can be controlled individually, which is convenient for adjusting the gas flow.

[0023] Furthermore, the mounting mechanism 3 includes a gas pipeline 301, a quick connector 302, a support clamp 303, a fixed shell 304 and an anti-skid pad 305. The other end of the flange 1 is fixedly connected to the gas pipeline 301, one end of the gas pipeline 301 is fixedly connected to the quick connector 302, the outer surface of the quick connector 302 is fixedly connected to the support clamp 303, the outer surface of the support clamp 303 is fixedly connected to the fixed shell 304, and the outer surface of the fixed shell 304 is fitted with the anti-skid pad 305. The support clamp 303, the fixed shell 304 and the anti-skid pad 305 are arranged so that during use, the quick connector 302 is used for the quick connection and disassembly of the gas control device and the gas channel, which is convenient for maintenance and overhaul and improves work efficiency. The gas enters the gas control mechanism 2 through the gas pipeline 301, and the outside of the quick connector 302 can be clamped on the gas channel to be connected through the support clamp 303. The support clamp 303 can be restored after undergoing a certain plastic deformation, and the anti-skid pad 305 on the surface increases the friction at the clamping point, so that the entire device can be stably clamped on the gas channel.

[0024] Furthermore, there are two support clamps 303 which are symmetrically distributed. The support clamps 303 are made of PP plastic. The air control device can be clamped on the pipe to be connected only when the support clamps 303 are clamped on both sides at the same time. PP plastic has great elasticity and plasticity.

[0025] Furthermore, the anti-skid pad 305 is fixedly connected to the outer surface of the support clamp 303 . The anti-skid pad 305 is made of rubber. The anti-skid pad 305 increases the friction at the clamping point. Rubber has good friction and anti-oxidation and corrosion properties.

[0026] Working principle: A gas control device. After the gas control device is installed with the required pipeline through the installation mechanism 3, the gas will first enter the cache box 201 from one end of the cache box 201 with a single slot. The other end of the cache box 201 has six slots connected to six solenoid valves 204 to divert the gas. The input end of the solenoid valve 204 is connected to one end of the six slots of another cache box 201, and the gas is then collected and output at one place. Each solenoid valve 204 can be independently controlled. The internal pressure of the two cache boxes 201 is detected by the pressure sensor 202 in the cache box 201, and the opening and closing of the solenoid valve 204 is calculated and controlled by the feedback circuit 203. When the pressure is too high, more solenoid valves 204 are opened to disperse the pressure received by a single solenoid valve 204. When the pressure is too low, some solenoid valves 204 are closed to increase the gas flow rate. The output end of the gas is connected to a manual valve 205 to manually control the passage of the gas. The quick connector 302 is used for quick connection and disassembly of the gas control device and the gas channel. The gas enters the gas control mechanism 2 through the gas pipeline 301. The outside of the quick connector 302 can be clamped on the gas channel to be connected through the support clamp 303. The support clamp 303 can be restored after undergoing a certain plastic deformation, and the anti-slip pad 305 on the surface increases the friction at the clamping point, thereby completing a gas control device.
