Description

Technical Field

[0001] This utility model relates to the field of filling valves, specifically a dual-channel filling valve rapid switching control device. Background Technology

[0002] A dual-channel filling valve is a type of valve used in hydraulic systems to achieve dual-channel fluid replenishment and control. Its working principle is based on the synergistic effect of valve core movement and pressure difference: when one side of the system (such as channel A) needs filling, the inlet pressure pushes the valve core to move in the corresponding direction, opening the channel A. Fluid flows into this circuit through the unidirectional structure, while simultaneously closing channel B to prevent cross-contamination. If channel B needs filling, the pressure signal drives the valve core to move in the opposite direction, opening the channel B and blocking channel A. In addition, the valve usually has an unloading or pressure-holding structure. When the system pressure reaches the set value, the valve core resets and cuts off the filling, ensuring that the two channels work independently as needed and avoiding mutual interference. It is widely used in hydraulic equipment that requires bidirectional fluid replenishment.

[0003] When using a dual-channel filling valve, the switching control essentially involves changing the drive signal (hydraulic, pneumatic, or electrical signal) to switch the valve core position, thereby opening or closing or switching the two fluid channels. This is typically achieved through the following devices for rapid switching control: Commonly used devices include:

[0004] 1. Electromagnetic directional valve (most commonly used) principle: The magnetic force generated by the electromagnet being energized / de-energized pushes the valve core to switch directions, directly controlling the pressure of the driving chamber (hydraulic or pneumatic) of the filling valve, thus achieving rapid switching.

[0005] 2. The pneumatic reversing valve uses compressed air as power and controls the opening and closing of the air passage to push the valve core to switch directions, thereby indirectly controlling the driving pressure of the filling valve.

[0006] Taking the AIRTAC directional control valve with specification model 4V210-08*AC220V as an example, in actual use, the pneumatic directional control valve controls the interruption or reversal of airflow through valve core switching. During this process, the airflow will generate instantaneous pressure shocks due to sudden opening / closing (i.e., the pneumatic version of the "water hammer effect"), forming pulsating airflow. The hose material is relatively soft and has low rigidity, making it difficult to resist this periodic pressure change. It will expand and oscillate with the airflow pulsation, thus causing shaking. At the connection between the hose and the directional control valve interface (such as quick-connect fittings or threaded fittings), repeated bending and pulling due to frequent shaking will cause the joint to loosen, the seals to wear, and eventually air leakage, reducing the pressure stability and efficiency of the pneumatic system. Utility Model Content

[0007] The purpose of this invention is to provide a dual-channel filling valve rapid switching control device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, a dual-channel filling valve rapid switching control device is provided, comprising a switching control device body, a force-bearing plate provided on the side wall of the switching control device body, an air inlet pipe installed at the bottom of the switching control device body, and an air outlet pipe A and an air outlet pipe B installed at the top of the switching control device body. A stabilizing frame is provided on the air outlet pipe A, the air outlet pipe B, and the air inlet pipe. The stabilizing frame includes an upper limit plate fixed to the side wall of the switching control device body, and a lower limit plate installed at the bottom of the upper limit plate.

[0009] Furthermore, force-bearing plates are installed on both sides of the main body of the switching control device, and both sets of force-bearing plates are rectangular.

[0010] Furthermore, the force-bearing plate has multiple sets of friction holes, the distance between adjacent sets of friction holes is consistent, and the friction holes are circular.

[0011] Furthermore, the stabilizer also includes an upper stabilizer, a rubber sleeve, and a lower stabilizer. One end of the upper limit plate is fixedly provided with a fixing frame A, and the other end of the upper limit plate is fixedly provided with a docking foot A.

[0012] Furthermore, the fixed frame A has an "S" shaped cross section, and the mating leg A has an "L" shaped cross section. The fixed frame A is snapped onto the upper stabilizer and fixed with bolts. Upper limit plates are installed on both sides of the upper stabilizer.

[0013] Furthermore, a connecting foot B is screwed to the bottom of the connecting foot A. The connecting foot B is fixedly set at the end of the lower limit piece. A fixing bracket B is fixedly set at the other end of the lower limit piece. The fixing bracket B is snapped onto the lower stabilizing seat and fixed by bolts.

[0014] Furthermore, the lower stabilizer and the upper stabilizer are arranged in parallel. The upper stabilizer has two sets of receiving ports inside. Rubber sleeves are fixedly installed on the inner walls of the two sets of receiving ports. Air outlet pipe A and air outlet pipe B are respectively inserted inside the two sets of rubber sleeves.

[0015] Furthermore, the lower stabilizing seat has an internal receiving port, and a rubber sleeve is fixedly installed on the inner wall of the receiving port. An air inlet pipe is inserted inside the rubber sleeve, and the ends of the upper limit plate and the lower limit plate are screwed to the side wall of the main body of the switching control device.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This solution uses stabilizers installed on the inlet pipe and outlet pipe A and outlet pipe B to limit and fix the inlet pipe, outlet pipe A and outlet pipe B, avoiding large-scale shaking between the air pipe and the main body of the switching control device. This prevents repeated bending and pulling caused by frequent shaking, which can lead to loose joints, wear of seals, and ultimately air leakage, thus reducing the pressure stability and efficiency of the pneumatic system.

[0018] 2. This solution increases surface roughness through multiple sets of friction holes on the force-bearing plate; when the operator needs to hold or push the main body of the switching control device, the friction holes can increase the friction between the hand and the force-bearing plate, effectively preventing slippage and ensuring more precise and stable control of the device during installation, debugging or manual operation, reducing operational errors caused by hand slippage.

[0025] Please see Figure 1-5 This utility model provides a dual-channel liquid filling valve rapid switching control device, including a switching control device body 1, a force-bearing plate 2 provided on the side wall of the switching control device body 1, an air inlet pipe 3 installed at the bottom of the switching control device body 1, and an air outlet pipe A31 and an air outlet pipe B32 installed at the top of the switching control device body 1. At the same time, a stabilizing frame 4 is provided on the air outlet pipe A31, the air outlet pipe B32 and the air inlet pipe 3. The stabilizing frame 4 includes an upper limit plate 42 fixed on the side wall of the switching control device body 1, and a lower limit plate 43 installed at the bottom of the upper limit plate 42.

[0026] Working Principle: In actual use, the main body 1 of the switching control device is equipped with an inlet pipe 3 and outlet pipes A31 and B32, respectively. A stabilizer 4 is installed on the inlet pipe 3, outlet pipes A31, and outlet pipe B32 to limit and fix them, preventing significant shaking between the air pipes and the main body 1 of the switching control device. This prevents repeated bending and pulling caused by frequent shaking, which could lead to loose joints, worn seals, and ultimately air leakage, reducing the pressure stability and efficiency of the pneumatic system. The specific working method of the stabilizer 4 is as follows: The upper stabilizer 40 above the stabilizer frame 4 has an air outlet pipe A31 and an air outlet pipe B32 inserted inside, while the lower stabilizer 44 below the stabilizer frame 4 has an air inlet pipe 3 inserted inside. Rubber sleeves 41 are installed in the perforations inside the lower stabilizer 44 and the upper stabilizer 40. The rubber sleeves 41 elastically cover the outside of the air pipes and fill the gap between the air pipes and the stabilizer. At the same time, the lower stabilizer 44 and the upper stabilizer 40 are fixed to the main body 1 of the switching control device by the lower limit piece 43 and the upper limit piece 42, respectively, to ensure the stability of the lower stabilizer 44 and the upper stabilizer 40 during operation and to prevent loosening.

[0027] As a preferred embodiment, force plates 2 are installed on both sides of the main body 1 of the switching control device, and both sets of force plates 2 are rectangular.

[0028] Multiple sets of friction holes 21 are provided on the force-bearing plate 2. The distance between two adjacent sets of friction holes 21 is the same, and the friction holes 21 are circular.

[0029] like Figure 1-3 As shown: Multiple sets of friction holes 21 on the force plate 2 can increase the surface roughness; when the operator needs to hold or push the main body 1 of the switching control device, the friction holes 21 can increase the friction between the hand and the force plate 2, effectively preventing slippage, ensuring more accurate and stable control of the device during installation, debugging or manual operation, and reducing operational errors caused by hand slippage.

[0030] In a preferred embodiment, the stabilizer 4 also includes an upper stabilizer 40, a rubber sleeve 41 and a lower stabilizer 44. One end of the upper limit plate 42 is fixedly provided with a fixing bracket A421, and the other end of the upper limit plate 42 is fixedly provided with a mating foot A422.

[0031] The fixed bracket A421 has an "S" shaped cross section, and the mating foot A422 has an "L" shaped cross section. The fixed bracket A421 is snapped onto the upper stabilizer 40 and fixed with bolts. Upper limit plates 42 are installed on both sides of the upper stabilizer 40.

[0032] The bottom of the mating foot A422 is screwed with mating foot B431. The mating foot B431 is fixedly set at the end of the lower limit piece 43. The other end of the lower limit piece 43 is fixedly set with a fixing bracket B432. The fixing bracket B432 is snapped onto the lower stabilizing seat 44 and fixed with bolts.

[0033] The lower stabilizer 44 and the upper stabilizer 40 are arranged in parallel. The upper stabilizer 40 has two sets of receiving ports inside. Rubber sleeves 41 are fixedly installed on the inner walls of the two sets of receiving ports. Air outlet pipes A31 and B32 are respectively inserted into the two sets of rubber sleeves 41.

[0034] The lower stabilizer 44 has an opening inside, and a rubber sleeve 41 is fixedly installed on the inner wall of the opening. An air inlet pipe 3 is inserted inside the rubber sleeve 41. The ends of the upper limit plate 42 and the lower limit plate 43 are screwed to the side wall of the main body 1 of the switching control device.

[0035] like Figure 1-4 As shown: The stabilizer 4, through the upper stabilizer 40 and the lower stabilizer 44, respectively limits and fixes the air outlet pipe A31, air outlet pipe B32, and air inlet pipe 3, directly preventing large-scale shaking between the air pipe and the main body 1 of the switching control device. This eliminates repeated bending and pulling caused by frequent shaking at the source, effectively preventing problems such as loose joints and worn seals, greatly reducing the probability of air leakage, ensuring the pressure stability of the pneumatic system, and improving the system's working efficiency. Secondly, the rubber sleeves 41 installed in the perforations inside the upper stabilizer 40 and the lower stabilizer 44 elastically cover the outside of the air pipe, not only filling the gap between the air pipe and the stabilizer, but also making the air pipe more firmly fixed in the stabilizer and reducing the relative shaking of the air pipe in the stabilizer. In addition to its dynamic properties, the rubber sleeve 41 also acts as a buffer, utilizing the elasticity of the rubber. When the trachea vibrates slightly due to airflow pulsations, the rubber sleeve 41 can absorb some of the vibration energy, preventing the vibration from being directly transmitted to the stabilizer and the main body 1 of the switching control device, thus further protecting the connection parts. Furthermore, the lower stabilizer 44 and the upper stabilizer 40 are fixed to the main body 1 of the switching control device via the lower limit plate 43 and the upper limit plate 42, respectively. This fixing method ensures the stability of the lower stabilizer 44 and the upper stabilizer 40 during operation, making them less prone to loosening. The stability of the stabilizer itself provides a solid foundation for limiting and fixing the trachea, ensuring that the stabilizer 4 functions reliably and for a long time, extending the service life of the trachea and the entire switching control device, and reducing maintenance costs and frequency.
