Description

Technical Field

[0001] This utility model relates to the connection of an intake valve body, specifically a sealing structure for connecting an intake valve body, belonging to the field of valve sealing technology. Background Technology

[0002] The intake valve consists of a valve body, a rotary check valve, a butterfly valve, and a control cylinder. The rotary check valve has its own counterweight and fluororubber sealing ring. When the compressor starts, the main unit draws in air, and due to the pressure difference, the check valve opens rapidly. When the compressor stops, the pressure difference is lost, and the check valve closes quickly and tightly under the control of the counterweight, ensuring no oil leakage during shutdown. The butterfly valve's opening and closing are controlled by the control cylinder. The butterfly valve opens or closes according to the piston extension length of the control cylinder, thereby regulating the compressor's intake volume. In chemical, energy, and compressor manufacturing fields, intake valves need to operate stably for extended periods under high pressure, high temperature, or corrosive media, such as acidic gases and oil mist mixtures. Traditional sealing structures are prone to leakage due to material aging, uneven thermal expansion, or mechanical vibration, affecting equipment safety and efficiency. If the compressor intake valve seal fails, it may cause system pressure fluctuations or energy waste.

[0003] In practical use, when the connection of the intake valve is subjected to mechanical vibration and impact pressure generated by sudden stops and starts of gas movement, the connection will vibrate and affect the tightness of the connection, and may even accelerate the wear of the threads at the connection. Therefore, it is necessary to design a sealing structure for valve body connection. Utility Model Content

[0025] This utility model embodiment provides a sealing structure for connecting the intake valve body.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An installation pipe 201 is fixedly connected to the right side of the outer wall of the valve body 1. A first extrusion block 202 is sleeved on the right side of the outer wall of the installation pipe 201. A sealing ring 203 is provided on the right side of the first extrusion block 202. A second extrusion block 204 is provided on the right side of the outer wall of the sealing ring 203. A first slope 205 is provided on the inner wall of the first extrusion block 202 corresponding to the outer wall of the sealing ring 203. A second slope 206 is provided on the inner wall of the second extrusion block 204 corresponding to the outer wall of the sealing ring 203. An installation block 207 is fixedly connected to the outer walls of the first extrusion block 202 and the second extrusion block 204. A connecting rod 208 is provided inside the installation block 207. A rotating block 20 is threadedly connected to the outer wall of the connecting rod 208. 9. The mounting pipe 201 is threadedly connected to the first extrusion block 202. The second extrusion block 204 has a connecting pipe 3 inside. The outer diameter of the connecting pipe 3 is smaller than the inner diameter of the sealing ring 203. The right side of the outer wall of the connecting pipe 3 is fixedly connected to the first fixing block 4. The valve body of the intake valve is connected with a sealing structure. By setting a rotating component, when the operator connects the valve body, the sealing ring 203 can be squeezed by the first extrusion block 202 and the second extrusion block 204, so that the sealing ring 203 applies pressure to the outer wall of the connecting pipe 3, thereby making the connection tight and reducing the probability of the valve body connection loosening due to mechanical vibration and gas movement, thus enhancing the practicality of the product.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The first fixing block 4 has a first locking block 5 on its outer wall, which is fixedly connected to the connecting pipe 3. The connecting pipe 3 has a connecting pipe 6 on its right side, and a second fixing block 7 is fixedly connected to the outer wall of the connecting pipe 6. The second fixing block 7 has a second locking block 8 on its outer wall, which is fixedly connected to the connecting pipe 6. A sealing ring 9 is provided on the left side of the inner wall of the connecting pipe 6, corresponding to the connecting pipe 3. A filter 10 is provided on the right side of the sealing ring 9, and the filter 10 is fixedly connected to the inner wall of the connecting pipe 6. An installation groove 11 is opened on the outer wall of the first locking block 5, corresponding to the second fixing block 7. A limit groove 12 is opened on the second locking block 8, corresponding to the first fixing block 4. The valve body of the intake valve is connected by a sealing structure. By setting the sealing ring 9 and the filter 10, the valve body can filter the gas through the filter 10 when it is working, protecting the inside of the valve body and keeping it in good working condition. When the operator needs to maintain the filter 10, it can be done by rotating the connecting pipe 6, which is convenient for the operator.

[0028] In use, when the operator needs to use the air intake valve, firstly, place the first compression block 202 on the right side of the outer wall of the mounting pipe 201, and then manually rotate the first compression block 202. When the first compression block 202 is in the appropriate position, it is connected to the mounting pipe 201 and the valve body 1. Then, place the connecting pipe 3 inside the sealing ring 203. At this time, the first compression block 202 and the second compression block 204 are respectively on both sides of the sealing ring 203. Then, connect the connecting rod 20... 8. Insert the rod into the mounting block 207. At this time, the operator rotates the rotating block 209, which moves on the outer wall of the connecting rod 208, applying pressure to the outer wall of the mounting block 207. Simultaneously, the first pressing block 202 and the second pressing block 204 are subjected to the force of the mounting block 207 and begin to move closer together. At this time, the sealing ring 203 is located between the first pressing block 202 and the second pressing block 204. When the first pressing block 202 and the second pressing block 204 approach each other, the first ramp 205 and the second ramp 206 respectively press against the sealing ring 203. Pressure is applied to the outer wall of the connecting pipe 3. The sealing ring 203 is made of rubber. After being subjected to external force, it begins to deform and exerts force on the outer wall of the middle installation pipe 201. At this time, the installation pipe 201 is subjected to the force of the sealing ring 203 to complete the installation action. When the valve works, mechanical vibration and gas movement are generated. The force on the connecting pipe 3 is transmitted to the sealing ring 203. The sealing ring 203 is subjected to the force of the first extrusion block 202 and the second extrusion block 204, and always maintains the sealing state of the connecting pipe 3. When the operator needs to remove the connecting pipe 3, the operator manually rotates the rotating block 209. At this time, the rotating block 209 moves on the outer wall of the connecting rod 208, releasing the limiting effect on the installation block 207. At this time, the installation block 207 moves, driving the first extrusion block 202 and the second extrusion block 204 to move. At this time, the sealing ring 203 is no longer subjected to the pressure of the first slope 205 and the second slope 206. The sealing ring 203 returns to its original state, releasing the pressure on the outer wall of the connecting pipe 3. At this time, the operator can manually remove the connecting pipe 3 to complete the disassembly.

[0029] When the operator needs to filter the gas in the intake valve, they manually align the left side of the outer wall of the connecting pipe 6 with the right side of the outer wall of the connecting pipe 3. At this time, the first locking block 5 and the second locking block 8 are in a staggered state. Then, the operator manually rotates the connecting pipe 6, and the second fixing block 7 and the second locking block 8 also rotate accordingly. When the connecting pipe 6 rotates to the appropriate angle, the first fixing block 4 enters the limiting groove 12, and the second locking block 8 limits the outer wall of the first fixing block 4. At the same time, the second fixing block 7 enters the mounting groove 11. At this time, the first locking block 5 limits the outer wall of the second fixing block 7. At this time, the connecting pipe 3 and the connecting pipe 6 are... In the limit connection state, the gas flowing inside the valve is filtered after passing through the filter 10, which removes impurities. When the operator needs to clean and maintain the filter 10, the operator manually rotates the connecting pipe 6, and the second fixing block 7 and the second locking block 8 rotate accordingly. At this time, the second fixing block 7 disengages from the installation groove 11, the first locking block 5 releases its limit on the second fixing block 7, and at the same time, the first fixing block 4 disengages from the limit groove 12, the second locking block 8 releases its limit on the first fixing block 4. At this time, the connecting pipe 3 is disconnected from the connecting pipe 6, and the operator can clean and maintain the filter 10 inside the connecting pipe 6.
