Description

Technical Field

[0001] The present invention relates to the technical field of valve bodies, and particularly to a rapid exchange guiding device capable of realizing automatic liquid interaction control and proportioning. Background Art

[0002] During production, it is necessary to instantaneously mix two liquids together to form a mixture, such as continuously using sulfuric acid of a certain concentration. Generally, a two-way valve is used to manually control the addition time of sulfuric acid and water to control the addition amount of both, so as to achieve the sulfuric acid with the required proportioning concentration.

[0003] In this control method, the exchange guiding time of the two-way valve is manually controlled. For example, a certain amount of water is added first, and then a certain amount of concentrated sulfuric acid is added. Since the manual control of the exchange process time of each liquid material is relatively long and the manual control error is relatively large, the proportioning stability of the mixture cannot be guaranteed.

[0031] An embodiment of the present invention discloses a quick-exchange guiding device, such as Figure 1 shown, the disclosed quick-exchange guiding device includes a valve body 100, an actuating part 200 and a driving part; the valve body 100 is provided with a liquid inlet channel and a liquid outlet channel 113, and liquid flows into the valve body 100 from the liquid inlet channel and after mixing in the valve body 100, flows out from the liquid outlet channel 113. As Figure 3 shown, the actuating part 200 can be provided with a first end 210 and a second end 220, the second end 220 is connected to the driving part, the first end 210 is connected to the valve body 100, and the driving part can drive the second end 220 to reciprocate between a first position ( Figure 1 shown) and a second position ( Figure 2 shown), driving the first end 210 to control the opening / closing of the liquid inlet channel.

[0032] Specifically, the liquid inlet channel can include a first liquid inlet channel 111 and a second liquid inlet channel 112, and the first liquid inlet channel 111 and the second liquid inlet channel 112 can input different liquids into the valve body 100. The quick-exchange guiding device disclosed in the embodiment of the present invention can also include a first limiting part and a second limiting part, the first limiting part and the second limiting part can be disposed on both sides of the valve body 100, and the two are symmetrically arranged. Correspondingly, on both sides of the second end 220, there are symmetrically arranged matching sides that respectively match the first limiting part and the second limiting part. As Figure 1 shown, when the second end 220 moves to the first position, the first limiting part is in limiting cooperation with one side matching side of the second end 220, the first liquid inlet channel 111 remains in an open state, and the second liquid inlet channel 112 remains in a closed state; as Figure 2As shown, when the second end 220 moves to the second position, the second limiting portion is in limiting cooperation with the other side of the second end 220, the second liquid inlet channel 112 remains open, and the first liquid inlet channel 111 remains closed.

[0033] In the disclosed embodiments of the present invention, there may be multiple first liquid inlet channels 111 for simultaneously inputting multiple different liquids into the valve body 100; similarly, there may also be multiple second liquid inlet channels 112. It should be noted that the multiple first liquid inlet channels 111 are opened or closed synchronously, and at the same time, the multiple second liquid inlet channels 112 are closed or opened synchronously.

[0034] In the disclosed embodiments of the present invention, the valve body 100 may include a valve wall 110, a valve core 120, and a rotating shaft 130. The liquid inlet channels and the liquid outlet channel 113 are both provided on the valve wall 110; one end of the rotating shaft 130 is provided inside the valve wall 110, and the other end is provided outside the valve wall 110, and the rotating shaft 130 can rotate relative to the valve wall 110 around the axis of the rotating shaft 130. One end of the rotating shaft 130 provided inside the valve wall 110 is fixedly connected to the valve core 120. The rotating shaft 130 can drive the valve core 120 to rotate around the axis of the rotating shaft 130 inside the valve wall 110. When the side of the valve core 120 facing away from the rotating shaft 130 rotates to the position of the liquid inlet channel, the liquid inlet channel can be closed, and when it rotates away from the position of the liquid inlet channel, the liquid inlet channel can be opened. One end of the rotating shaft 130 provided outside the valve wall 110 is fixedly connected to the first end 210 of the actuating portion 200. Specifically, the first end 210 may be provided with a connection hole 211, and the connection hole 211 may be provided with internal threads. One end of the rotating shaft 130 provided outside the valve wall 110 is provided with a threaded section matching the internal threads. The first end 210 and the rotating shaft 130 are fixedly connected by threads. When the second end 220 of the actuating portion 200 reciprocates between the first position and the second position, the actuating portion 200 can drive the rotating shaft 130 to rotate around its axis, driving the side of the valve core 120 facing away from the rotating shaft 130 to move between the first liquid inlet channel 111 and the second liquid inlet channel 112, so as to realize the rapid interactive opening / closing between the liquid inlet channels.

[0035] In the embodiment disclosed in the present invention, the driving part may include a driving member (not shown in the figure), a first eccentric wheel 310 and a connecting rod 320. The first eccentric wheel 310 may be arranged on the right side of the action part 200. The driving member may drive the first eccentric wheel 310 to rotate around the first eccentric wheel axis 311. One end of the connecting rod 320 is rotatably connected to the side of the first eccentric wheel 310 farther from the first eccentric wheel axis 311, and the other end is connected to the second end 220 of the action part 200. When the first eccentric wheel 310 rotates, the second end 220 may be driven to reciprocate between the first position and the second position. When the connecting part of the connecting rod 320 and the first eccentric wheel 310 rotates to the leftmost side of the first eccentric wheel axis 311, the second end 220 moves to the first position; when the connecting part of the connecting rod 320 and the first eccentric wheel 310 rotates to the rightmost side of the first eccentric wheel axis 311, the second end 220 moves to the second position.

[0036] Further, the driving part may also include a base 330 and a bracket 340, the base 330 is arranged on the left side of the first eccentric wheel 310, the bracket 340 is arranged on the base 330, and the end of the connecting rod 320 away from the first eccentric wheel 310 is rotatably connected to the bracket 340. Specifically, the bracket 340 may include a crossbar and two vertical bars, the crossbar is slidably arranged on the base 330, and the two ends of the crossbar are respectively fixed with a vertical bar, and the second end 220 is arranged between the two vertical bars and is respectively connected to the two vertical bars through the elastic member 350. During the rotation of the first eccentric wheel 310, the bracket 340 reciprocates and slides on the base 330, driving the second end 220 to reciprocate between the first position and the second position, and the elastic member 350 can not only increase the residence time of the second end 220 at the first position or the second position, but also play a buffering role in the steering process of the reciprocating motion of the second end 220, so that the rapid interactive operation between the liquid inlet channels is carried out smoothly. Preferably, the elastic member 350 may be a spring.

[0037] In an alternative embodiment of the present invention, the first limiting portion includes a first limiting member 420 and a second eccentric wheel 410. The first limiting member 420 is relatively fixed to the base 330 through a first limiting rotating shaft 421, and the first limiting rotating shaft 421 is disposed at the middle portion of the first limiting member 420. The first limiting member 420 can rotate around the first limiting rotating shaft 421. A second eccentric wheel 410 is disposed on the lower side of the first limiting member 420. The second eccentric wheel 410 is drivingly connected to the driving member and is driven by the driving member to rotate around the axis 411 of the second eccentric wheel and synchronously with the first eccentric wheel 310. One end of the first limiting member 420 is connected to the base 330 through a first limiting compression member 430, and the other end is pressed against the second eccentric wheel 410 under the pressure of the first limiting compression member 430. A first limiting side for limiting cooperation with the second end 220 is further disposed at the connection end of the first limiting member 420 and the first limiting compression member 430. During the rotation of the second eccentric wheel 410, the first limiting side can move up and down to realize the conversion between the limiting and non-limiting states of the second end 220.

[0038] Similarly, the second limiting portion includes a second limiting member 520 and a third eccentric wheel 510. The second limiting member 520 is relatively fixed to the base 330 through a second limiting rotating shaft 521, and the second limiting rotating shaft 521 is disposed at the middle portion of the second limiting member 520. The second limiting member 520 can rotate around the second limiting rotating shaft 521. A third eccentric wheel 510 is disposed on the lower side of the second limiting member 520. The third eccentric wheel 510 is drivingly connected to the driving member and is driven by the driving member to rotate around the axis 511 of the third eccentric wheel and synchronously with the first eccentric wheel 310. One end of the second limiting member 520 is connected to the base 330 through a second limiting compression member 530, and the other end is pressed against the third eccentric wheel 510 under the pressure of the second limiting compression member 530. A second limiting side for limiting cooperation with the second end 220 is further disposed at the connection end of the second limiting member 520 and the second limiting compression member 530. During the rotation of the third eccentric wheel 510, the second limiting side can move up and down to realize the conversion between the limiting and non-limiting states of the second end 220.

[0039] Preferably, the first limiting compression member 430 and the second limiting compression member 530 can be compression springs.

[0040] It should be noted that the first eccentric wheel 310, the second eccentric wheel 410, and the third eccentric wheel 510 rotate at the same angular velocity.

[0041] Such as Figure 1As shown, when the connecting part of the connecting rod 320 and the first eccentric wheel 310 rotates to the position closest to the bracket 340, the first limiting member 420 presses against the closest end of the second eccentric wheel 410 to the axis 411 of the second eccentric wheel, and the first limiting side performs the limiting operation of the second end 220 at the first position; at this time, the second limiting member 520 presses against the farthest end of the third eccentric wheel 510 from the axis 511 of the third eccentric wheel. The three rotating shafts continue to rotate, and the bracket 340 slides in the direction close to the first eccentric wheel 310 under the action of the connecting rod 320. Due to the limiting effect of the first limiting member 420 on the second end 220 and the balanced pulling force of the two elastic members 350, the second end 220 remains at the first position; during this process, the first limiting side moves in the direction towards the base 330. When it disengages from the second end 220, the second end 220 moves from the first position to the second position under the action of the pulling force of the connecting rod 320 and the restoring force of the elastic member 350. During this process, the second limiting side moves in the direction away from the base 330.

[0042] As Figure 2 As shown, when the connecting part of the connecting rod 320 and the first eccentric wheel 310 rotates to the position farthest from the bracket 340, the second limiting member 520 presses against the closest end of the third eccentric wheel 510 to the axis 511 of the third eccentric wheel, and the second limiting side performs the limiting operation of the second end 220 at the second position; at this time, the first limiting member 420 presses against the farthest end of the second eccentric wheel 410 from the axis 411 of the second eccentric wheel. The three rotating shafts continue to rotate, and the bracket 340 slides in the direction away from the first eccentric wheel 310 under the action of the connecting rod 320. Due to the limiting effect of the second limiting member 520 on the second end 220 and the balanced pulling force of the two elastic members 350, the second end 220 remains at the second position; during this process, the second limiting side moves in the direction towards the base 330. When it disengages from the second end 220, the second end 220 moves from the second position to the first position under the action of the pulling force of the connecting rod 320 and the restoring force of the elastic member 350. During this process, the first limiting side moves in the direction away from the base 330. By circulating in this way, the second end 220 reciprocates between the first position and the second position; the residence time of the second end 220 at the first position and the second position can be respectively controlled by setting the heights of the first limiting side and the second limiting side, and further control the opening / closing time of the first liquid inlet channel 111 and the second liquid inlet channel 112; the opening / closing time of the first liquid inlet channel 111 and the second liquid inlet channel 112 can also be controlled by controlling the rotation speeds of the three eccentric wheels.

[0043] In another alternative embodiment of the present invention, different from the above alternative embodiment, the first limiting compression member 430 may not be provided. A connecting rod is rotatably connected to the end of the second eccentric wheel 410 that is farther from the axis 411 of the second eccentric wheel, and the other end of the connecting rod is rotatably connected to the end of the first limiting member 420 that is away from the first limiting side. Similarly, the second limiting compression member 530 may not be provided. A connecting rod is rotatably connected to the end of the third eccentric wheel 510 that is farther from the axis 511 of the third eccentric wheel, and the other end of the connecting rod is rotatably connected to the end of the second limiting member 520 that is away from the second limiting side. The rest of the settings are the same as those in the above alternative embodiment, and will not be elaborated herein.

[0044] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
