Description

Technical Field

[0001] This utility model relates to the field of valve opening and closing technology, specifically to a remote valve control integrated machine. Background Technology

[0002] Valves, as flow regulation and opening / closing control components, are widely used in various fields such as industry, agriculture, petrochemicals, medicine and health, and even people's work and life. However, due to factors such as equipment structure and layout requirements, many manual valves need to be installed in special locations, some of which need to be installed underground, in confined spaces, or at a distance, making it inconvenient for operators to enter and operate the valves. These factors make it difficult for the valve opening device to access the valve, causing difficulties in opening and closing the valve.

[0003] Patent CN 221424032 U discloses a gate valve opening device, including a housing for fixing to the yoke flange of the gate valve. The housing has a mounting cavity, and the upper and lower surfaces of the housing have a first through cavity and a second through cavity, which are arranged opposite to each other and communicate with the mounting cavity. In the mounting cavity, a bearing housing ring, a tapered roller bearing, a bearing shaft ring, a driven gear, and a valve stem nut are stacked sequentially from bottom to top. The valve stem nut is used for threaded connection with the valve stem of the gate valve. The gate valve opening device also includes a drive assembly, which includes a drive element and a drive gear. The drive gear is located in the mounting cavity and meshes with the driven gear. The drive element is mounted on the housing, and the output end of the drive element is connected to the drive gear.

[0004] However, the device still has the following problems: due to friction, corrosion and rust, the drive component is unable to provide the power required to open the valve. If the power is forcibly increased, it is easy to damage the valve opening device. Utility Model Content

[0005] To address the problems existing in the prior art, a remote valve control integrated machine is provided to solve the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model proposes a remote valve control integrated machine, including a housing and a motor. The housing is provided with a connecting rod for opening and closing the valve. A fixed block connected to the connecting rod is rotatably provided on the housing. A large slide groove and a small slide groove are symmetrically opened on the circumference of one end of the fixed block. The motor is connected to an impact block, and the impact block and the motor are connected by a compression spring. A large slider and a small slider that cooperate with the fixed block are fixed on the impact block. The width of the large slider is greater than the width of the small slide groove and the small slider.

[0008] Preferably, the length of the large slide groove is greater than the length of the large slider, and the length of the small slide groove is greater than the length of the small slider.

[0009] Preferably, one end of the motor has a power shaft, the end of the power shaft is fixed with a spline shaft, a lifting sleeve is slidably sleeved on the spline shaft, one end of the lifting sleeve is fixed with a lifting foot that can lift the impact block, and a lifting plate that cooperates with the lifting sleeve is fixed on the fixed block.

[0010] Preferably, the lifting plate has a chamfer on one side that mates with the lifting sleeve, and the lifting plate is offset from the large and small sliding grooves.

[0011] Preferably, a flywheel is fixedly sleeved on the power shaft.

[0012] Preferably, a speed reducer is detachably connected to the housing, an impact shell is detachably connected to the lower end of the speed reducer, the fixed block is rotatably mounted on the impact shell, and the upper end of the motor is detachably connected to the lower end of the impact shell.

[0013] Preferably, the reducer has an input sleeve and an output sleeve, the input sleeve is connected to the fixed block, and one end of the output sleeve is connected to the connecting rod.

[0014] Preferably, one end of the connecting rod that extends into the output sleeve is machined to form a first inclined surface, and a fixed shaft is also slidably connected inside the output sleeve. One end of the fixed shaft is machined to form a second inclined surface that matches the connecting rod, and the connecting rod and the fixed shaft are connected by bolts.

[0015] Preferably, an encoder is provided at the other end of the output sleeve.

[0016] Preferably, the housing also has a battery, a transmission module, and a relay fixed to it.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model is equipped with a large slider and a small slider. When the connecting rod encounters significant resistance and cannot continue to rotate, the large slider and the small slider slide out of the groove. During rotation, because the width of the large slider is greater than the width of the small groove, the large slider passes over the small groove and continues to rotate until it reaches the position of the large groove after nearly a full rotation. Only then will it enter the large groove under the action of the compression spring and continue to rotate to impact the fixed block. Compared with the prior art, where two sliders are symmetrically arranged and can only rotate 180 degrees to impact, this solution can rotate nearly a full rotation, thus having sufficient inertia and impact force to open the valve.

[0019] 2. A flywheel is fixedly sleeved on the power shaft of this utility model. When the valve stem is difficult to continue rotating due to rust or other reasons, causing the fixed block to be unable to rotate, the flywheel has a certain mass, which allows the power shaft to continue rotating under the action of inertia. This can reduce the occurrence of motor overload damage caused by sudden deceleration of the motor. The flywheel uses its own mass to keep the power shaft rotating, which can enable the impact block to have sufficient speed to impact.

[0020] 3. In this utility model, the reducer is connected to the housing, the impact shell is connected to the reducer, and the motor is connected to the impact shell. This allows the motor to be suspended in the air and not in contact with the housing or other equipment, which is beneficial for motor heat dissipation and enables the motor to output stably.

Detailed Implementation

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] refer to Figures 1-11 This embodiment proposes a remote valve control integrated machine, including a housing 1 and a motor 7. The housing 1 is provided with a connecting rod 2 for opening and closing the valve. A fixed block 3 connected to the connecting rod 2 is rotatably provided on the housing 1. A large sliding groove 18 and a small sliding groove 19 are opened in the circumferential direction at one end of the fixed block 3. The motor 7 is connected to an impact block 4. The impact block 4 and the motor 7 are connected by a compression spring 5. A large slider 12 and a small slider 13 that cooperate with the fixed block 3 are fixed on the impact block 4. The width of the large slider 12 is greater than the width of the small sliding groove 19 and the small slider 13.

[0037] When not overloaded, the compression spring 5 keeps the large slider 12 and the small slider 13 within the large slide groove 18 and the small slide groove 19, causing the large slider 12 and the small slider 13 to press against the large slide groove 18 and the small slide groove 19, thereby driving the fixed block 3 to rotate. When overloaded, the large slider 12 and the small slider 13 slide out from the large slide groove 18 and the small slide groove 19. After rotating one revolution, the large slider 12 and the small slider 13 re-enter the large slide groove 18 and the small slide groove 19. As the large slider 12 and the small slider 13 rotate, they impact the fixed block 3, causing the valve stem to loosen.

[0038] When rotating, since the width of the large slider 12 is greater than the width of the small slide groove 19, after the large slider 12 reaches the position of the small slide groove 19, it will pass over the small slide groove 19 and continue to rotate until it rotates almost one full circle and returns to the position of the large slide groove 18. Only then will it enter the large slide groove 18 under the action of the compression spring 5. At this time, the small slider 13 also re-enters the small slide groove 19 and continues to rotate in the large slide groove 18 and the small slide groove 19. The side walls of the large slider 12 and the small slider 13 impact the fixed block 3. The large slider 12 and the small slider 13 can rotate almost one full circle, thus having enough inertia and impact force to open the valve.

[0039] The length of the large slide 18 is greater than the length of the large slider 12, and the length of the small slide 19 is greater than the length of the small slider 13.

[0040] The length of the groove is greater than the length of the slider, which allows the slider to enter the groove more accurately and avoids the situation where the slider goes over the groove because the groove length is too short.

[0041] One end of the motor 7 has a power shaft 6, and the end of the power shaft 6 is fixed with a spline shaft 8. A lifting sleeve 9 is slidably sleeved on the spline shaft 8. One end of the lifting sleeve 9 is fixed with a lifting foot that can lift the impact block 4. A lifting plate 10 that cooperates with the lifting sleeve 9 is fixed on the fixing block 3.

[0042] When the valve stem can rotate normally, the power shaft 6 drives the spline shaft 8 and the lifting sleeve 9 to rotate. At this time, the compression spring 5 between the spline shaft 8 and the impact block 4 is in a compressed state. The compression spring 5 keeps the large slider 12 and the small slider 13 in the large slide groove 18 and the small slide groove 19, thereby driving the fixed block 3 to rotate.

[0043] When the valve stem becomes difficult to rotate due to rust, corrosion, wear, or other reasons, the fixing block 3 can no longer drive the valve stem to rotate. At this time, the power shaft 6 of the motor 7 drives the spline shaft 8 to continue rotating. The spline shaft 8 drives the lifting sleeve 9 to rotate. After the lifting sleeve 9 contacts the lifting plate 10, the lifting sleeve 9 is lifted by the lifting plate 10. At the same time, the lifting sleeve 9 drives the impact block 4 to lift, causing the large slider 12 and the small slider 13 to slide out of the large slide groove 18 and the small slide groove 19 until the large slider 12 and the small slider 13 re-enter the large slide groove 18 and the small slide groove 19. This causes a circumferential impact and vibration on the fixing block 3. The short-term, high-intensity vibration causes a small displacement between the valve stem and the valve body, breaking the "locked state" between the valve stem and the valve body, thereby restoring the valve stem to normal rotation.

[0044] The lifting plate 10 has a chamfer on one side that mates with the lifting sleeve 9, and the lifting plate 10 is offset from the large slide 18 and the small slide 19.

[0045] The chamfering allows the lifting sleeve 9 to contact the lifting plate 10, making the lifting process smoother and preventing jamming. The lifting plate 10 is offset from the large slide 18 and the small slide 19, so that when the large slider 12 and the small slider 13 impact, the lifting plate 10 and the lifting sleeve 9 are not in contact, ensuring the smooth impact of the large slider 12 and the small slider 13.

[0046] A flywheel 22 is fixedly mounted on the power shaft 6.

[0047] The flywheel 22 has a certain mass, which enables the power shaft 6 to continue rotating under inertia. This reduces the occurrence of motor 7 overload damage caused by sudden deceleration of motor 7. The flywheel 22 uses its own mass to maintain the rotation speed, which enables the impact block 4 to have sufficient speed to impact.

[0048] If the impact block 4 cannot maintain its rotational speed, the impact force will decrease or even fail to be generated after the slider passes the top of the groove due to its slow speed.

[0049] A reducer 11 is detachably connected to the housing 1, and an impact housing 17 is detachably connected to the lower end of the reducer. A fixing block 3 is rotatably mounted on the impact housing 17, and the upper end of the motor 7 is detachably connected to the lower end of the impact housing 17.

[0050] The reducer 11 is connected to the housing 1, the impact housing 17 is connected to the reducer 11, and the motor 7 is connected to the impact housing 17. This allows the motor 7 to be suspended in the air and not in contact with the housing 1 or other equipment, which is beneficial for the heat dissipation of the motor 7 and enables the motor to output stably.

[0051] The speed reducer 11 can further increase the torque of the motor 7, which is beneficial for opening and closing the valve 23.

[0052] The reducer 11 is detachably connected to the housing 1 by bolts. The impact housing 17 and the reducer 11 are fixed by a flange. The motor 7 and the impact housing 17 are fixed by a flange. The flanges are connected and fixed by bolts and nuts.

[0053] The reducer 11 has an input sleeve and an output sleeve. The input sleeve is connected to the fixed block 3, and one end of the output sleeve is connected to the connecting rod 2.

[0054] One end of the connecting rod 2 that extends into the output sleeve is machined to form a first inclined surface. A fixed shaft 14 is also slidably connected inside the output sleeve. One end of the fixed shaft 14 is machined to form a second inclined surface that matches the connecting rod 2. The connecting rod 2 and the fixed shaft 14 are connected by bolts 15.

[0055] The fixed shaft 14 has a stepped hole. The larger part of the stepped hole is used to place the bolt head of the bolt 15, and the smaller part is used for the stud part of the bolt 15 to pass through. The diameter of the smaller part is larger than the diameter of the stud of the bolt 15. The connecting rod 2 has a threaded hole that matches the stud.

[0056] By tightening bolt 15, the connecting rod 2 is brought close to the fixed shaft 14 and coaxial with the fixed shaft 14. Since the diameter of the small hole of the stepped hole is larger than the diameter of the bolt 15 stud, the first inclined surface of the connecting rod 2 and the second inclined surface of the fixed shaft 14 are misaligned, thereby causing the fixed shaft 14 to press against the inside of the output sleeve of the reducer 11, thus completing the fixation of the connecting rod 2.

[0057] An encoder 16 is provided at the other end of the output sleeve.

[0058] The encoder 16 is fixed to the reducer 11 or the housing 1 via a connecting piece. The encoder 16 rotates coaxially with the connecting rod 2 and can detect the rotation state of the connecting rod 2, and is used to measure parameters such as speed, angular displacement and angular velocity.

[0059] The housing 1 also has a battery, a transmission module and a relay 20 fixed on it.

[0060] The transmission module can transmit and receive data for the entire device, and the relay 20 can control the working state of the motor 7 and control the start and stop of the motor 7.

[0061] An outer cover 21 is detachably connected to the housing 1, and a display screen is provided on the outer cover 21.

[0062] refer to Figure 10-11 By adjusting the internal layout, the position of the reducer 11 output sleeve and connecting rod 2 on the housing 1 can be adjusted, thereby changing the installation position of the device, which can adapt to different valves and facilitate installation and commissioning in various environments. Detailed implementation method:

[0064] S1: When in use, by sending a signal to the transmission module, the transmission module sends the signal to the relay 20, and the relay 20 controls the motor 7 to be energized and rotate.

[0065] S2: When not overloaded, the compression spring 5 keeps the large slider 12 and the small slider 13 in the large slide groove 18 and the small slide groove 19, causing the large slider 12 and the small slider 13 to press against the large slide groove 18 and the small slide groove 19. The large slider 12 and the small slider 13 drive the fixed block 3 to rotate through friction and the side wall of the slider.

[0066] When overloaded, the fixed block 3 can no longer drive the valve stem to rotate. At this time, the power shaft 6 of the motor 7 drives the spline shaft 8 to continue rotating. The spline shaft 8 drives the lifting sleeve 9 to rotate. After the lifting sleeve 9 contacts the lifting plate 10, the lifting sleeve 9 is lifted by the lifting plate 10. At the same time, the lifting sleeve 9 drives the impact block 4 to lift, so that the large slider 12 and the small slider 13 slide out from the large slide groove 18 and the small slide groove 19.

[0067] S3: The large slider 12 and the small slider 13 continue to rotate with the spline shaft 8. After rotating one revolution, they re-enter the large slide groove 18 and the small slide groove 19, impacting and vibrating the fixed block 3. After vibration, the valve stem and valve 23 become loose. At this time, the impact block 4 continues to drive the valve stem to rotate under the drive of the motor, realizing the opening and closing control of valve 23.
