Description

Technical Field

[0001] The utility model relates to a static push regulating valve for pneumatically conveying large particle materials, belonging to the technical field of static push regulating valves. Background Art

[0002] A static push control valve, also known as a static balancing valve or self-operated flow control valve, is a valve used to precisely control the flow, pressure, and temperature of fluid media. It plays a vital role in industrial automation control systems and is widely used in various fields, including petroleum, chemical, electric power, metallurgy, and environmental protection. Among these applications, static push control valves are used for pneumatic conveying of large particles.

[0003] However, the existing static push regulating valve is usually fixed with multiple bolts. Therefore, when it needs to be disassembled or installed, the bolts need to be repeatedly tightened. This process is cumbersome and time-consuming. At the same time, since the conveyed material is large particles, the static push regulating valve will vibrate to a certain extent due to the collision of particles during the conveying process. After long-term use, the bolts may become loose due to the influence of vibration, which may cause the static push regulating valve to fall off.

[0004] Therefore, a static push regulating valve for pneumatic conveying of large particle materials is proposed. Utility Model Content

[0010] Further preferably, the surfaces of the two connecting rods are movably connected to support plates via bearings, and the two support plates are fixedly mounted on the left and right sides of the surface of the mounting frame.

The inner side of the mounting frame 3 is movably connected with a driven gear 205. The inner sides of the eight screw rods 206 are fixedly installed on the outer sides of the eight driven gears 205. The surfaces of the eight driven gears 205 are meshed with the surfaces of the two gear rings 204. The output ends on both sides of the bidirectional motor 201 are fixedly connected with connecting rods 202. The outer sides of the two connecting rods 202 are fixedly installed with driving gears 203. The surfaces of the two driving gears 203 are meshed with the surfaces of the two gear rings 204. The eight sockets 5 and the eight L-shaped rods 208 are equidistantly arranged in the circumferential direction, and the inner cavity of the sockets 5 and the size of the L-shaped rods 208 match each other.

[0029] By setting up the mounting mechanism 2, through the output of the bidirectional motor 201, the driving gear 203, the gear ring 204 and the driven gear 205 cooperate with each other, and the screw rod 206 drives the screw block 207 to move inward. At this time, the L-shaped rod 208 is inserted into the inner cavity of the socket 5, thereby completing the connection between the static push type regulating valve body 1 and the pipe body 4. Compared with the use of bolts for fixing, this installation method can save the steps of tightening the bolts and save the time spent on installation or disassembly. At the same time, due to the output of the bidirectional motor 201, it can effectively avoid the vibration of the static push type regulating valve body 1 during operation, which makes the bolts fall off during installation, thereby ensuring the stability of the static push type regulating valve body 1 during installation and facilitating use by operators.

[0030] Example 2

[0032] By providing a support plate 210, the connecting rod 202 can be supported to prevent the connecting rod 202 from bending due to the influence of the weight of the driving gear 203, thereby affecting the transmission of the kinetic energy of the bidirectional motor 201. By providing a limit rod 209, the movement of the screw block 207 can be limited to prevent the screw block 207 from deflecting when moving, thereby affecting the connection between the static push type regulating valve body 1 and the pipe body 4. By providing an arc groove 211 and a slider 212, the rotation of the gear ring 204 can be limited to prevent the gear ring 204 from deflecting when rotating, thereby affecting the connection between the static push type regulating valve body 1 and the pipe body 4. By providing a sealing ring 6, the connection between the pipe body 4 and the static push type regulating valve body 1 can be sealed to prevent gas penetration during operation of the static push type regulating valve body 1, thereby affecting the transportation of particulate matter.

[0033] When the present invention is in operation: after the static push regulating valve body 1 is placed on the inner side of the pipe body 4, through the output of the bidirectional motor 201, the connecting rod 202 drives the driving gear 203 to rotate synchronously, and causes the gear ring 204 to rotate. Through the rotation of the gear ring 204, the driven gear 205 rotates synchronously, and drives the screw rod 206 to rotate. The screw block 207 moves inward along the surface thread of the screw rod 206, so that the L-shaped rod 208 moves inward and is inserted into the inner cavity of the socket 5, completing the installation of the static push regulating valve body 1 as a whole.
