[0002] The gas dispatching system needs to distribute the gas from different sources to different pipelines or uses according to demand. The diverter valve can realize the precise distribution and control of the gas flow to ensure that each pipeline or use can get the appropriate gas supply;

[0003] Traditionally, the diverter valve used for gas dispatch is fixed by connecting the flange of the valve with the flange of the pipeline and fixing them together with bolts, or by connecting the thread of the valve with the thread of the pipeline and fixing the valve on the pipeline by using the self-locking characteristics of the thread;

[0004] Traditional diverter valves for gas scheduling have the following problems: flange connections and threaded connections are easily affected by external environmental factors, such as vibration, impact or corrosion, which may cause the connection to loosen or be damaged, reducing the sealing of the connection. For this reason, we propose a diverter valve for gas scheduling. Utility Model Content

[0013] Furthermore, the fixing mechanism includes a pressure block, a slide groove, an avoidance groove and a rubber pad. The avoidance grooves are opened at the front and rear ends of the outer surface of the valve body. The front and rear ends of the same avoidance groove are both provided with slide grooves.

The fixing mechanism 3 includes a pressure block 31, a slide groove 34, an avoidance groove 36 and a rubber pad 37.

After the internal thread ring 39 is moved, it contacts the chamfered surface of the adjacent pressure block 31 and applies an extrusion force to the pressure block 31, so that the pressure block 31 is squeezed and moved toward the center of the valve body 2. However, the movement of the pressure block 31 drives the slide The column 35 moves along the inner wall of the sliding hole 33. This process also causes the spring 32 to be stretched, and the internal threaded ring 39 continues to move until it completely covers the pressure block 31, thereby driving the rubber pad 37 on the pressure block 31 to contact and squeeze the outer surface of the gas pipe.

Then the shunt pipe 6 is connected to the external pipeline through the flange 7. However, a single flange is used to facilitate the connection between various types of pipelines, containers or equipment. When gas is needed, the battery 9 is regulated by the external single-chip microcomputer to transmit electrical energy to the single-chip microcomputer 15 to ensure normal operation. After receiving the signal, the single-chip microcomputer 15 regulates the pressure sensor 8 and sets the pressure threshold. Based on the feedback information of the pressure sensor 8, the opening or closing degree of the shunt ball 14 can be automatically adjusted to keep the pressure in the pipeline within a safe range and ensure the stability and reliability of the gas supply. Then the motor 5 is regulated to operate, and the output shaft of the motor 5 drives the worm 12 to rotate. The worm 12 The worm gear 10 meshes with the worm gear 10 and rotates, thereby realizing the rotation of the worm gear 10. The worm gear 10 drives the rotating shaft 11 to rotate through the sealed bearing, and the rotating shaft 11 drives the sphere 14 to rotate. However, there are three diversion ports 13 on the sphere 14. Through the rotation of the rotating shaft 11, these diversion ports 13 can be rotated to different positions. When diversion processing is required, the single-chip microcomputer 15 issues a command to regulate the operation of the motor 5, driving the three diversion ports 13 on the sphere 14 to rotate to the appropriate position to realize diversion processing, thereby realizing precise adjustment of the diversion ports 13 through the worm gear transmission.
