Description

Technical Field

[0001] The invention relates to the technical field of pipeline valves, and in particular to an unsaturated polyester resin control valve. Background Art

[0002] Unsaturated polyester resin is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by the polycondensation of unsaturated dibasic acid diols or saturated dibasic acid unsaturated diols. Usually, the polyesterification polycondensation reaction is carried out at 190-220°C until the expected acid value is reached. After the polyesterification polycondensation reaction is completed, a certain amount of vinyl monomer is added while hot to form a viscous liquid. Such a polymer solution is called unsaturated polyester resin.

[0003] During the transportation of unsaturated polyester resin, a control valve is needed to control the opening and closing of the transportation pipeline. The opening and closing part of the ball valve control valve is a sphere with a through hole. In actual work, the ball valve control valve has a high viscosity when transporting unsaturated polyester resin. When the ball valve control valve is closed, the unsaturated polyester resin inside does not flow. If the ball valve control valve is closed for a long time, the unsaturated polyester resin inside is easy to stick and solidify on the surface of the inner flow channel of the sphere, reducing the area of ​​the inner flow channel cross-section, thereby reducing the flow coefficient, and ultimately reducing the flow rate, affecting the flow performance of the ball valve control valve.

[0004] For example, in a ball valve provided by authorization announcement No. CN112923092B, the operator pulls the locking rod to compress the locking spring of the locking rod and withdraw it from the locking groove, and then rotates the valve stem; the valve stem drives the arc block to rotate, and the valve stem will not drive the rotating rod to rotate under the force of the tension spring. When the valve stem drives the valve ball to rotate to the coaxial position of the flow channel and the cleaning plate, the rotating rod and the shoulder contact, and then when the valve stem rotates, the shoulder will drive the rotating rod to rotate, so that the fixed block rotates with the valve ball as the center until the flow channel axis and the first connecting pipe axis are perpendicular, and the ball valve becomes disconnected; in this process, because the second gear and the arc rack are meshed, the second gear drives the rotating shaft to keep rotating all the time, so the rotating shaft drives the first gear to rotate, and because the first gear and the first rack on the sliding block are meshed, the sliding block drives the cleaning plate to enter the flow channel and extend out of the flow channel to scrape off the silt on the inner wall of the flow channel. By setting up a cleaning mechanism, the cleaning mechanism can be extended into the flow channel of the valve ball through the rotation of the valve stem to scrape off the sludge on the inner wall. No separate adjustment mechanism is required. The design is ingenious and will not affect the operation of the valve ball.

[0005] It has a major disadvantage: in the process of cleaning the flow channel by the cleaning mechanism, since the direction of the flow channel is parallel to the ground, when scraping off the internal sludge, the sludge can only be cleaned by pushing the cleaning mechanism, which greatly reduces the cleaning efficiency of the sludge. Summary of the invention

[0006] The embodiment of the present application provides an unsaturated polyester resin control valve, which solves the problem in the prior art that during the process of cleaning the flow channel by a cleaning mechanism, since the direction of the flow channel is parallel to the ground, when the internal sludge is scraped off, the sludge can only be cleaned by the pushing of the cleaning mechanism, which greatly reduces the cleaning efficiency of the sludge, and realizes changing the direction of the flow channel on the valve ball. The telescopic cylinder drives the cleaning part to extend into the flow channel from above. During the extension process, the unsaturated polyester resin scraped off can fall due to its own weight, thereby improving the cleaning effect on the unsaturated polyester resin that is relatively firmly attached to the flow channel.

[0049] Secondly, by changing the outer side of the cleaning piece into a cleaning capsule, the cleaning capsule can be inflated. When cleaning the flow channel, the expansion of the cleaning capsule can improve the degree of contact with the inner wall of the flow channel, thereby improving the cleaning effect. At the same time, after the cleaning of the inner wall of the flow channel is completed, the cleaning capsule can be retracted so that the cleaning capsule does not contact the inner wall of the flow channel, thereby effectively preventing the unsaturated polyester resin from reattaching to the inner wall of the flow channel, thereby reducing the cleaning efficiency.

[0050] Thirdly, the water in the storage cavity can be intermittently sprayed out by the electromagnet support block to spray and clean the unsaturated polyester resin in the flow channel; at the same time, the water between the extrusion block and the cleaning capsule can also soak and clean the inner wall of the flow channel after being scraped by the cleaning capsule. The outer side of the extrusion block fits the inner wall of the flow channel, which can scrape off the unsaturated polyester resin left on the inner wall of the flow channel, thereby improving the cleaning effect; the sprayed water can also impact and clean the unsaturated polyester resin attached to the surface of the cleaning capsule, thereby preventing the sediment from falling on the flow channel or the valve ball when it is retracted; the electromagnet support block can continuously change the magnetic pole, thereby adsorbing and repelling the extrusion block multiple times, and the flow channel can be scraped multiple times in one descent, thereby further improving the cleaning effect;

[0051] Fourthly, by controlling the degassing of different cavities in the cleaning capsule, the position of the gap between the cleaning capsule and the inner wall of the flow channel is changed, the position of the water spray is automatically changed, and the cleaning effect on the inner wall of the flow channel and the surface of the cleaning capsule is improved; the electromagnet support block is powered on to adsorb the iron ball and then powered off, and the iron ball is elastically reset by the cleaning capsule, so that the iron ball can hit the unsaturated polyester resin in the flow channel, thereby improving the cleaning effect; at the same time, the electromagnet support block in the cleaning capsule is powered on to adsorb the iron ball, and the iron ball is rebounded after power is cut off, and the surface of the cleaning capsule vibrates. The vibration can shake off the unsaturated polyester resin attached to the surface of the cleaning capsule, and it can be completely shaken off through multiple vibrations, thereby improving the cleaning effect.

[0071] Embodiment 1: Figure 1-Figure 5 As shown, the present application discloses an unsaturated polyester resin control valve, comprising a main body component 100, a regulating component 200 and a closing component 300;

[0072] The main assembly 100 includes a valve body 110, a groove 112, a port 113, a sealing gasket 120, a bracket 140 and a telescopic cylinder 150;

[0073] The valve body 110 is a rectangular parallelepiped that is continuous along its length direction. The length direction of the valve body 110 is parallel to the ground. The cavity of the valve body 110 is cylindrical. The cavity of the valve body 110 is provided with a groove 112. The groove 112 is spherical. A sealing gasket 120 is fixed in the groove 112.

[0074] The valve body 110 is symmetrically provided with a through-port 113, which passes through the valve body 110 and is connected to the groove 112. The through-port 113 is cylindrical, and the axis of the through-port 113 is perpendicular to the ground.

[0075] The bracket 140 is fixed to the upper side of the valve body 110, and the telescopic cylinder 150 is fixed to the top side of the bracket 140, and the telescopic direction of the telescopic cylinder 150 is perpendicular to the ground;

[0076] The regulating assembly 200 is fixedly disposed on one side of the valve body 110;

[0077] The closure assembly 300 includes a valve ball 310;

[0078] The valve ball 310 is spherical and matches the groove 112. The valve ball 310 is rotatably disposed in the groove 112.

[0079] The valve ball 310 is provided with a flow channel 311, which is cylindrical. In the initial state, the flow channel 311 of the valve ball 310 is perpendicular to the ground, the axis of the flow channel 311 and the axis of the port 1 113 are in the same straight line, and the flow channel 311 is connected to the port 1 113;

[0080] Also included is a cleaning assembly 400, wherein the cleaning assembly 400 includes a connecting rod 410 and a cleaning member 420;

[0081] The connecting rod 410 is fixed to the lower end of the telescopic cylinder 150, and the cleaning member 420 is fixed to the lower end of the connecting rod 410;

[0082] The telescopic cylinder 150 is activated to extend the cleaning member 420 into the opening 113 and the flow channel 311;

[0083] The telescopic cylinder 150 can make the cleaning member 420 pass through the flow channel 311 and the two openings 113;

[0084] The main body assembly 100 further includes a fixing hole 111, a second through hole 114 and a fixing ring 130;

[0085] One side of the valve body 110 is provided with a fixing hole 111, and the fixing holes 111 are multiple and evenly spaced in a ring shape;

[0086] The valve body 110 has a second opening 114 on one side. The second opening 114 is cylindrical, and the axis of the second opening 114 is parallel to the ground. The second opening 114 is connected to the groove 112.

[0087] The fixing hole 111 and the second through-port 114 are both located on the same side as the adjustment assembly 200;

[0088] There are two fixing rings 130, which are respectively sleeved and fixed at two ends of the valve body 110 in the length direction, and the fixing rings 130 are provided with threaded holes;

[0089] The adjustment assembly 200 includes a fixing rod 210, a handle 220, a third opening 221 and a fixing bolt 230;

[0090] One end of the fixing rod 210 passes through the second opening 114 and is fixed on the valve ball 310. The end of the valve ball 310 away from the fixing rod 210 is rotatably connected in the groove 112. The handle 220 is fixed to the end of the fixing rod 210 away from the valve ball 310. Both ends of the handle 220 in the length direction are provided with a third opening 221. Both the third opening 221 and the fixing hole 111 are threaded. The outer side of the fixing bolt 230 is threaded. There are two fixing bolts 230, which correspond to the two third openings 221 respectively. One end of the fixing bolt 230 is threaded in the third opening 221 and the fixing hole 111.

[0091] During use, when it is necessary to clean the flow channel 311 of the valve ball 310, the telescopic cylinder 150 drives the connecting rod 410 and the cleaning member 420 to descend, and the cleaning member 420 enters the flow channel 311, and the inner wall of the flow channel 311 is cleaned by the cleaning member 420. The cleaning member 420 can extend out of the through-port 1 113 below the valve body 110 to push out the unsaturated polyester resin on the inner wall of the cleaning member 420, and then the cleaning member 420 is driven to reset by the telescopic cylinder 150 and pulled out from the flow channel 311; when the valve body 110 needs to work normally to convey materials, the fixing bolt 230 is pulled out, and the handle 220 is rotated 90 degrees to connect the flow channel 311 with the cavity in the valve body 110, and then the fixing bolt 230 is fixed in the through-port 3 221 and the fixing hole 111 to fix the position of the valve ball 310.

[0092] Compared with the prior art, the direction of the flow channel 311 on the valve ball 310 is changed, and the telescopic cylinder 150 drives the cleaning member 420 to extend into the flow channel 311 from above. During the extension process, the scraped unsaturated polyester resin can fall due to its own weight, thereby improving the cleaning effect of the unsaturated polyester resin that is relatively firmly attached to the flow channel 311.

[0093] Embodiment 2: When the embodiment 1 is in use, the telescopic cylinder 150 drives the cleaning member 420 to extend from the top of the flow channel 311 to scrape the unsaturated polyester resin in the flow channel 311. However, during use, a large amount of unsaturated polyester resin will adhere to the surface of the cleaning member 420, resulting in the unsaturated polyester resin attached to the surface of the cleaning member 420 will re-attach to the flow channel 311 when the telescopic cylinder 150 drives the cleaning member 420 to rise and retract, resulting in a poor cleaning effect. Based on this, the solution of the embodiment 1 is cleaned, as shown in FIG. Figure 6-Figure 8 As shown:

[0094] The cleaning member 420 includes a support block 421, a cleaning capsule 422, an air pump member 440 and an air delivery pipe 470;

[0095] The support block 421 is fixed to one end of the connecting rod 410 away from the telescopic cylinder 150, and the cleaning bag 422 is wrapped around the outside of the support block 421;

[0096] The connecting rod 410 has an air supply pipeline in it, and one end of the air supply pipeline is connected to the cleaning bag 422;

[0097] The air pump component 440 is fixed on the upper side of the bracket 140 , and an air pump is provided inside the air pump component 440 . An air supply pipe 470 is fixed to the output end of the air pump, and an end of the air supply pipe 470 away from the air pump is connected to an end of the air supply line away from the cleaning bag 422 .

[0098] When the cleaning capsule 422 is not in use, the cleaning capsule 422 is in an unexpanded state. When the cleaning capsule 422 is needed, the air pump in the air pump member 440 is used to inflate the cleaning capsule 422 to expand the cleaning capsule 422. The telescopic cylinder 150 drives the cleaning member 420 to extend from the top of the flow channel 311. During the extension process, the cleaning capsule 422 is close to the inner wall of the flow channel 311. The unsaturated polyester resin scraped off by the cleaning capsule 422 can fall due to its own weight. When the telescopic cylinder 150 drives the cleaning member 420 to rise and retract, the gas in the cleaning capsule 422 is discharged through the air pump in the air pump member 440, so that the cleaning capsule 422 does not contact the flow channel 311 during the rising process.

[0099] By converting the outer side of the cleaning piece 420 into a cleaning capsule 422, the cleaning capsule 422 can be inflated. When cleaning the flow channel 311, the expansion of the cleaning capsule 422 can improve the fit with the inner wall of the flow channel 311 and improve the cleaning effect. At the same time, after the cleaning of the inner wall of the flow channel 311 is completed, the cleaning capsule 422 can be retracted so that the cleaning capsule 422 does not contact the inner wall of the flow channel 311, thereby effectively preventing the unsaturated polyester resin from re-adhering to the inner wall of the flow channel 311 and reducing the cleaning efficiency.

[0100] Embodiment 3: When embodiment 2 is in use, the expansion of cleaning capsule 422 improves the fit between cleaning capsule 422 and the inner wall of flow channel 311, and the contraction of cleaning capsule 422 prevents the unsaturated polyester resin on the surface of cleaning capsule 422 from adhering to the inner wall of flow channel 311. However, when in use, the cleaning effect of the inner wall of flow channel 311 by cleaning capsule 422 alone is poor, and the unsaturated polyester resin is always attached to the surface of cleaning capsule 422. After being reset by telescopic cylinder 150, the unsaturated polyester resin on the surface of cleaning capsule 422 will fall off due to its own weight within a certain period of time, and may fall and adhere to valve ball 310 or flow channel 311 when rotating valve ball 310, resulting in poor cleaning effect. Based on this, the scheme of embodiment 2 is improved, such as Fig. 9 As shown:

[0101] The cleaning assembly 400 further includes an extrusion block 430 and a delivery tube 450;

[0102] The extrusion block 430 is a cylindrical body that penetrates from top to bottom. The sealing sleeve of the extrusion block 430 is arranged on the connecting rod 410. The maximum diameter of the extrusion block 430 is consistent with the maximum diameter of the flow channel 311. The lower side of the extrusion block 430 is fixed with a magnet.

[0103] When the extrusion block 430 and the cleaning capsule 422 enter the flow channel 311, a storage cavity is formed between the extrusion block 430, the cleaning capsule 422 and the flow channel 311;

[0104] The delivery pipe 450 is fixed on the extrusion block 430 and communicates with the storage cavity;

[0105] One end of the delivery pipe 450 away from the extrusion block 430 is connected to the water inlet device;

[0106] The support block 421 is a DC electromagnet;

[0107] The materials of the valve body 110 , the valve ball 310 and the telescopic cylinder 150 are not ferromagnetic.

[0108] The cleaning capsule 422 is inflated by the air pump in the air pump member 440 to expand the cleaning capsule 422, and the telescopic cylinder 150 drives the cleaning member 420 to extend from the top of the flow channel 311. During the extension process, the electromagnet support block 421 is energized to absorb the magnet under the extrusion block 430, so that the extrusion block 430 follows the support block 421 into the flow channel 311. After that, the electromagnet support block 421 is powered off, and a certain amount of water is injected into the storage cavity formed between the flow channel 311, the cleaning capsule 422 and the extrusion block 430 through the water inlet device connected to one end of the delivery pipe 450. During the gradual descent of the telescopic cylinder 150, the electromagnet support block 421 is intermittently energized. During the energization process, the electromagnet support block 421 absorbs the extrusion block 430, so that the extrusion block 430 The pressing block 430 presses the water downward, so that the water squeezes the expanded cleaning capsule 422 below, and a gap is generated between the cleaning capsule 422 and the flow channel 311. Water is sprayed out from the gap to spray and clean the unsaturated polyester resin in the flow channel 311; the water between the pressing block 430 and the cleaning capsule 422 can also soak and clean the inner wall of the flow channel 311 after being scraped by the cleaning capsule 422, thereby improving the cleaning effect; the outer side of the pressing block 430 fits the inner wall of the flow channel 311, and can scrape off the residual unsaturated polyester resin on the inner wall of the flow channel 311; at the same time, the sprayed water can impact and clean the surface of the cleaning capsule 422; the electromagnetic support block 421 continuously changes the magnetic pole, so that the pressing block 430 can be adsorbed and repelled multiple times, and the flow channel 311 can be scraped multiple times in one descent.

[0109] By adsorbing the squeezing block 430 through the electromagnet support block 421, the water in the storage cavity can be intermittently sprayed out to spray and clean the unsaturated polyester resin in the flow channel 311; at the same time, the water between the squeezing block 430 and the cleaning capsule 422 can also soak and clean the inner wall of the flow channel after being scraped by the cleaning capsule 422. The outer side of the squeezing block 430 fits the inner wall of the flow channel 311, which can scrape off the residual unsaturated polyester resin on the inner wall of the flow channel 311, thereby improving the cleaning effect; the sprayed water can also impact and clean the unsaturated polyester resin attached to the surface of the cleaning capsule 422, thereby preventing sludge from falling on the flow channel 311 or the valve ball 310 when it is retracted; by continuously changing the magnetic poles through the electromagnet support block 421, the squeezing block 430 can be adsorbed and repelled multiple times, and the flow channel 311 can be scraped multiple times in one descent, thereby further improving the cleaning effect.

[0110] Embodiment 4: When the embodiment 3 is in use, the electromagnet support block 421 adsorbs the extrusion block 430, so that the water in the storage cavity can be sprayed out intermittently to spray and clean the unsaturated polyester resin in the flow channel 311. However, in the process of squeezing and spraying water, the position of the water spray cannot be controlled, resulting in uneven cleaning of the inner wall. At the same time, the cleaning effect of the surface of the cleaning capsule 422 by spraying water is poor. Based on this, the solution of the embodiment 3 is improved, such as Figure 10-12 As shown:

[0111] The cleaning assembly 400 further includes a separation membrane 423 and an iron ball 460;

[0112] The iron ball 460 is fixed to the outer wall of the cleaning capsule 422, and there are a plurality of the iron balls 460, which are evenly spaced.

[0113] The separation membrane 423 is C-shaped and is located in the cleaning capsule 422. There are multiple separation membranes 423. The multiple separation membranes 423 are evenly spaced and fixed in the cleaning capsule 422 in an annular shape. The multiple separation membranes 423 divide the cavity of the cleaning capsule 422 into multiple cavities that are not connected to each other.

[0114] The connecting rod 410 has a plurality of air delivery pipelines in it. The number of the air delivery pipelines is the same as the number of cavities separated by the separation membrane 423 in the cleaning capsule 422, and they correspond one to one. One end of the air delivery pipeline is connected to the cavity separated by the separation membrane 423 in the cleaning capsule 422.

[0115] The number of air pumps in the air pump component 440 is the same as the number of air delivery pipelines, and they correspond one to one.

[0116] The air can be released from different cavities in the cleaning capsule 422 to create a gap between the cleaning capsule 422 and the inner wall of the flow channel, and water can be sprayed out from the gap to change the position of the water spraying by itself; the electromagnet support block 421 is powered on and then powered off to adsorb the iron ball 460, so that the iron ball 460 can hit the unsaturated polyester resin in the flow channel 311, thereby improving the cleaning effect; when the cleaning capsule 422 extends out of the opening 113 at the lower end, the cleaning capsule 422 is in an expanded state, and the electromagnet support block 421 in the cleaning capsule 422 is powered on to adsorb the iron ball 460 to deform the cleaning capsule 422. After complete adsorption, the electromagnet support block 421 is powered off to make the iron ball 460 rebound, and the surface of the cleaning capsule 422 vibrates. The vibration can shake off the unsaturated polyester resin attached to the surface of the cleaning capsule 422, and it can be completely shaken off by multiple vibrations, effectively preventing the silt attached to the outside of the cleaning capsule 422 from falling on the flow channel and the valve ball, thereby improving the cleaning effect.

[0117] By controlling the degassing of different cavities in the cleaning capsule 422, the position of the gap between the cleaning capsule 422 and the inner wall of the flow channel is changed, and the position of the water spray is changed automatically, so as to improve the cleaning effect on the inner wall of the flow channel 311 and the surface of the cleaning capsule 422; the electromagnet support block 421 is powered on to adsorb the iron ball 460 and then powered off, and the iron ball 460 is elastically reset by the cleaning capsule 422, so that the iron ball 460 can hit the unsaturated polyester resin in the flow channel 311, thereby improving the cleaning effect; at the same time, the electromagnet support block 421 in the cleaning capsule 422 is powered on to adsorb the iron ball 460, and the iron ball 460 is rebounded after the power is turned off, and the surface of the cleaning capsule 422 vibrates, and the vibration can shake off the unsaturated polyester resin attached to the surface of the cleaning capsule 422, and it can be completely shaken off through multiple vibrations, thereby improving the cleaning effect.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
