Description

Technical Field

[0001] This utility model relates to the technical field of valve operation auxiliary equipment, specifically to a manual valve quick-opening adapter. Background Technology

[0002] Manual valves are widely used in industrial production and energy pipeline networks to control the flow of fluid media. However, in practice, especially with large-diameter manual valves or valves that have become rusted or jammed after long-term use, opening them often requires a lot of manpower and is inefficient. Traditional manual opening methods not only increase the labor intensity of operators, but in emergencies (such as pipeline repairs and fire emergencies), the slow opening speed may also delay the best response time, leading to the expansion of the accident or greater economic losses.

[0003] Furthermore, some manual valves are installed in confined spaces or at high altitudes, posing certain safety hazards during manual operation and making it difficult to ensure uniform opening force, which may damage the valve itself. To address the difficulties and low efficiency of manual valve opening, avoid safety risks and economic losses caused by operational delays, and ensure quick, safe, and labor-saving valve operation, a rapid-opening adapter for manual valves is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a quick-opening adapter for manual valves.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A manual valve quick-opening adapter includes an adapter main plate. One end face of the adapter main plate has several threaded holes for connecting a plurality of first and second connecting rods. The bottom of each second connecting rod has a latch, and a rotatable locking anti-disengagement rod is connected to the latch. The bottom side of the locking anti-disengagement rod has a hinge hole that mates with the first connecting rod. The other end face of the adapter main plate is fixedly connected to an electric wrench connection part. The connecting surface of the electric wrench connection part has a positioning pin hole, inside which is installed an elastic ball that mates with the electric wrench sleeve.

[0006] This utility model's manual valve adapter connects to various valve-compatible clamping and locking devices on one end of the adapter main plate, while the other end is equipped with an electric wrench connection point. This enables rapid opening and closing of manual valves under pressure, facilitating control of the operation process. It is widely applicable to various manual valves such as industrial gate valves, pipeline ball valves, and globe valves. Through its efficient power transmission structure and adaptable design, it effectively solves the technical problems of low opening efficiency and high labor intensity of traditional manual valves under high torque and emergency conditions.

[0007] Furthermore, when the locking anti-disengagement rod rotates 90° toward the first connecting rod, the first connecting rod and the second connecting rod are at the same height, and the length of the locking anti-disengagement rod is not shorter than the straight-line distance between the first connecting rod and the second connecting rod.

[0008] Under pressure, insert the No. 1 connecting rod and the No. 2 connecting rod into both sides of the inner ring connecting rod of the manual valve. Then rotate the locking anti-disengagement rod 90° towards the No. 1 connecting rod. At this time, the lower sides of the No. 1 connecting rod and the No. 2 connecting rod are on the same horizontal line. This ensures that each inner ring connecting rod of the manual valve is subjected to uniform force during the rotation of the manual valve adapter, thereby achieving uniform opening force and reducing safety hazards.

[0009] Furthermore, the size of the hinge hole is 2-5mm larger than the bottom size of the first connecting rod.

[0010] The locking anti-derailment rod located on the lower side of the second connecting rod primarily serves to lock and prevent detachment. The hinge hole at the bottom of the locking anti-derailment rod is designed to fit the bottom dimensions of the first connecting rod. When the locking anti-derailment rod rotates 90° towards the first connecting rod, the first connecting rod fits perfectly into the hinge hole. During the rotation of the adapter, the presence of the hinge hole is crucial for achieving anti-derailment locking. The external electric opening and closing process is rapid; the lack of a locking anti-derailment device would pose a significant risk to the operator.

[0011] Furthermore, the number of the first connecting rod and the second connecting rod is at least three pairs, and they are evenly distributed on the inner ring of the manual valve, with one pair of the first connecting rod and the second connecting rod arranged in parallel.

[0012] Manual valves typically have three connecting rods on their inner ring, though some may have more than three. Regardless of the number, the first and second connecting rods of this device are arranged parallel to each other and evenly distributed within the inner ring of the manual valve. This ensures a more even clamping force when the first and second connecting rods hold the connecting rods of the inner ring of the manual valve. It is also compatible with various types of manual valves, such as industrial gate valves, pipeline ball valves, and globe valves. Even if the manual valve has six connecting rods on its inner ring, and this adapter only has three pairs of connecting rods, as long as the three connecting rods are evenly clamped at 120° angles, uniform opening and closing force can still be achieved.

[0013] Furthermore, each pair of the first connecting rods is located on one side of the inner ring connecting rod of the manual valve, and the second connecting rod is located on the other side of the inner ring connecting rod of the manual valve.

[0014] Connecting rod number one is located on one side of the inner ring connecting rod of the manual valve. When the adapter opens the manual valve, connecting rod number one mainly bears the force. Connecting rod number two is located on the other side of the inner ring connecting rod of the manual valve. When the adapter closes the manual valve, connecting rod number two mainly bears the force. Connecting rods number one and number two are located on both sides of the inner ring connecting rod of the manual valve. Through the constraint forces on both sides, the connecting rod of the inner ring of the manual valve is tightly clamped during the rotation of the adapter.

[0015] Furthermore, at least three connecting threaded holes are provided at equal gradient intervals along the radial direction of the adapter main disk.

[0016] The adapter plate of this device has three or more threaded holes spaced at gradient intervals. These threaded holes are used to install the No. 1 and No. 2 connecting rods mentioned above. Considering that the adapter needs to adapt to valve handwheels or valve stems of different sizes (50-300mm in diameter), the threaded holes are arranged radially and gradient along the adapter plate. This allows for adaptive adjustment of the clamping range and locking of the connecting rod installation position according to the different inner diameters of the valve handwheel or valve stem inner ring.

[0017] Furthermore, the electric wrench connecting part has a hexagonal structure, and the positioning pin hole is located at the center of the connecting surface of the electric wrench connecting part.

[0018] The electric wrench connector is used to connect to an external electric wrench socket. The hexagonal design of the connector is compatible with all commonly used electric wrench sockets on the market. By adding a locating pin hole at the center of the electric wrench connector, operators can easily and quickly connect the electric wrench to the adapter of this invention. In emergency situations, such as pipeline repairs or fire emergencies, a slow opening speed may delay the best handling opportunity, leading to the escalation of the accident or greater economic losses.

[0019] Furthermore, the elastic ball is connected to a spring, one end of which is fixed in the spring hole of the positioning pin hole, and the elastic ball engages with the circular recess inside the electric wrench sleeve.

[0020] The ball joint is connected to a spring, which allows for inward and outward expansion and contraction. One end of the spring is fixed in the spring hole. There is a small circular recess inside the electric wrench sleeve, and the ball joint can be locked into the small circular recess. It generally will not fall off. It takes force to separate the electric wrench connection part from the external electric wrench sleeve. This design can achieve further restraint and ensure a reliable connection between the electric wrench connection part and the external electric wrench sleeve.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a manual valve quick-opening adapter, which significantly improves operational efficiency. By replacing manual operation with electric drive, the opening time of large-diameter manual valves is reduced from 30-60 minutes in the traditional manual method to 5-10 minutes, which can buy valuable time for disaster relief in emergency situations. The labor-saving effect is significant. With the power output of the electric wrench and the transmission structure of the device, the force required by the operator can be reduced by more than 80%, effectively reducing labor intensity, and is particularly suitable for high-frequency valve operation scenarios. The safety is higher. The anti-detachment locking device protects against the device falling off and injuring people during operation. At the same time, electric operation reduces the direct contact time of personnel in dangerous environments (such as heights and narrow spaces), reducing safety risks. 2. This utility model, through the locking anti-disengagement rod and hinge hole designed on the lower side of the second connecting rod, enables the effective anti-disengagement and locking of the adapter when the connecting rod clamps the connecting rod of the inner ring of the manual valve, thus ensuring the safety of the operator when the adapter is connected to an external electric wrench sleeve; 3. The adapter main plate of this utility model is provided with connecting threaded holes at equal gradient intervals in the radial direction, so that the connecting rod connected to it can be adapted to valve handwheels or valve stems of different shapes and diameters (50-300mm) such as round, square, and polygonal, thereby improving the scalability of the adapter. 4. The parallel arrangement of the No. 1 and No. 2 connecting rods, evenly distributed within the inner ring of the manual valve, effectively ensures the uniformity of the opening force and avoids damage to the valve itself; the electric wrench connection part connects to the external electric wrench sleeve, solving the technical problems of low opening efficiency and high labor intensity of traditional manual valves under high torque and emergency conditions.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "number one", "number two", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0025] The specific embodiments of this utility model are described in conjunction with the appendix. Figure 1 and attached Figure 2 Let me explain further.

[0026] A manual valve quick-opening adapter includes an adapter main plate 1. One end face of the adapter main plate 1 has several threaded holes 2. Several first connecting rods 3 and second connecting rods 4 are threadedly connected to the threaded holes 2. The bottom of the second connecting rod 4 is provided with a buckle 5. A rotatable locking anti-disengagement rod 6 is connected to the buckle 5. The bottom side of the locking anti-disengagement rod 6 is provided with a hinge hole that mates with the first connecting rod 3. The other end face of the adapter main plate 1 is fixedly connected to an electric wrench connecting part 7. The connecting surface of the electric wrench connecting part 7 is provided with a positioning pin hole 701. An elastic ball that mates with the electric wrench sleeve 8 is installed inside the positioning pin hole 701.

[0027] By setting a locking anti-disengagement rod 6 and a hinge hole on the lower side of the second connecting rod 4, the adapter effectively prevents disengagement and locks the connecting rod when the first connecting rod 3 and the second connecting rod 4 clamp the connecting rod of the inner ring of the manual valve. This ensures operator safety when the adapter is connected to an external electric wrench sleeve. The electric wrench connection part 7 connects to the external electric wrench sleeve 8, solving the technical problems of low opening efficiency and high labor intensity of traditional manual valves under high torque and emergency conditions. This utility model's manual valve adapter connects a clamping device and a locking anti-disengagement device compatible with various valves to one end of the adapter main plate 1, and sets an electric wrench connection part 7 on the other end, enabling rapid opening and closing of manual valves under pressure. This facilitates control of the operation process and is widely applicable to various manual valves such as industrial gate valves, pipeline ball valves, and globe valves. Through an efficient power transmission structure and adaptable design, it effectively solves the technical problems of low opening efficiency and high labor intensity of traditional manual valves under high torque and emergency conditions.

[0028] The locking anti-slip rod 6 can be fitted with an anti-slip rubber pad on the inside of the buckle 5, and a manual locking knob is designed on the outside. After the connecting rod is locked into the valve handwheel, tightening the knob achieves rigid fixation, further preventing slippage and detachment during operation. In use, the No. 1 and No. 2 connecting rods for multi-specification valves are fixed to the handwheel or valve stem of the manual valve via the locking anti-slip rod 6. Then, the electric wrench sleeve 8 is connected and fixed to the electric wrench connection part 7. The electric wrench rotation is adjusted according to the valve opening direction, and starting the electric wrench can quickly open the valve.

[0029] Furthermore, when the locking anti-disengagement rod 6 rotates 90° toward the first connecting rod 3, the first connecting rod 3 and the second connecting rod 4 are at the same height, and the length of the locking anti-disengagement rod 6 is not shorter than the straight-line distance between the first connecting rod 3 and the second connecting rod 4.

[0030] Under pressure, insert connecting rod 3 and connecting rod 4 into both sides of the inner ring connecting rod of the manual valve. Then, rotate the locking anti-disengagement rod 6 90° toward connecting rod 3. At this time, the lower sides of connecting rod 3 and connecting rod 4 are on the same horizontal line, ensuring that each inner ring connecting rod of the manual valve is subjected to uniform force during the rotation of the manual valve adapter, thereby achieving uniform opening force and reducing safety hazards.

[0031] Furthermore, the size of the hinge hole is 2-5mm larger than the bottom size of the first connecting rod 3.

[0032] The locking anti-detachment rod 6 located on the lower side of the second connecting rod 4 primarily serves to lock and prevent detachment. The hinge hole at the bottom of the locking anti-detachment rod 6 is designed to fit the bottom dimensions of the first connecting rod 3. When the locking anti-detachment rod 6 rotates 90° towards the first connecting rod 3, the first connecting rod 3 fits perfectly into the hinge hole. During the rotation of the adapter, the presence of the hinge hole is crucial for achieving anti-detachment locking. The external electric opening and closing process is rapid; the lack of a locking anti-detachment device would pose a significant risk to the operator.

[0033] Furthermore, the number of the first connecting rod 3 and the second connecting rod 4 is at least three pairs and they are evenly distributed on the inner ring of the manual valve, with one pair of the first connecting rod 3 and the second connecting rod 4 arranged in parallel.

[0034] Manual valves typically have three connecting rods on their inner ring, though some may have more than three. Regardless of the number, in this device, connecting rod 3 (number one) and connecting rod 4 (number two) are arranged parallel to each other and evenly distributed within the inner ring of the manual valve. This ensures a more even clamping force when connecting rods 3 and 4 hold the connecting rods of the inner ring of the manual valve. It is also compatible with various types of manual valves, such as industrial gate valves, pipeline ball valves, and globe valves. Even if the manual valve has six connecting rods on its inner ring, and this adapter only has three pairs of connecting rods, as long as the three connecting rods are evenly clamped at 120° angles, uniform opening and closing force can still be achieved.

[0035] Furthermore, each pair of the first connecting rod 3 is located on one side of the inner ring connecting rod of the manual valve, and the second connecting rod 4 is located on the other side of the inner ring connecting rod of the manual valve.

[0036] Connecting rod 3 (number 1) is located on one side of the inner ring connecting rod of the manual valve. When the adapter opens the manual valve, connecting rod 3 is primarily under stress. Connecting rod 4 (number 2) is located on the other side of the inner ring connecting rod of the manual valve. When the adapter closes the manual valve, connecting rod 4 is primarily under stress. Connecting rods 3 and 4, located on opposite sides of the inner ring connecting rod of the manual valve, tightly clamp the inner ring connecting rod of the manual valve during the rotation of the adapter through the constraint forces on both sides.

[0037] Furthermore, at least three of the connecting threaded holes 2 are provided at equal gradient intervals along the radial direction of the adapter main disk 1.

[0038] The adapter plate 1 of this device has three or more threaded holes 2 spaced at gradient intervals. These threaded holes 2 are used to install the first connecting rod 3 and the second connecting rod 4 mentioned above. Considering that the adapter needs to adapt to valve handwheels or valve stems of different sizes (50-300mm in diameter), the threaded holes 2 are arranged radially and gradiently along the adapter plate. This allows for adaptive adjustment of the clamping range and locking of the connecting rod installation position according to the different inner diameters of the valve handwheels or valve stems.

[0039] Furthermore, the electric wrench connecting part 7 has a hexagonal structure, and the positioning pin hole 701 is located at the center of the connecting surface of the electric wrench connecting part 7.

[0040] The electric wrench connector 7 is used to connect to an external electric wrench socket 8. The hexagonal design of the electric wrench connector 7 is compatible with all commonly used electric wrench sockets 8 on the market. By adding a positioning pin hole 701 at the center of the electric wrench connector, operators can easily and quickly connect the electric wrench to the adapter of this invention. In emergency situations, such as pipeline repairs or fire emergencies, a slow opening speed may delay the best handling opportunity, leading to the escalation of the accident or greater economic losses.

[0041] Furthermore, the elastic ball is connected to a spring, one end of which is fixed in the spring hole of the positioning pin hole 701, and the elastic ball engages with the circular recess inside the electric wrench sleeve 8.

[0042] The ball contains a spring that allows for inward and outward expansion and contraction. One end of the spring is fixed in the spring hole. The inside of the electric wrench sleeve 8 has a small circular recess, which the ball can just fit into. It generally will not fall off, and it takes force to separate the electric wrench connection part from the external electric wrench sleeve. This design can achieve further restraint and ensure a reliable connection between the electric wrench connection part 7 and the external electric wrench sleeve 8.

[0043] In the above embodiments, when encountering severe valve jamming, mechanical assistance can be used. The specific operating steps are as follows: 1. Check device connections: Ensure that the adapter is securely connected to the manual valve and the electric wrench sleeve 8; 2. Start the electric wrench at low speed: Allow the electric wrench to apply torque at a low speed; 3. Use mechanical tapping: If an abnormally increased torque is found, a rubber mallet can be used to gently tap the valve handwheel or valve stem to help loosen the stuck parts; 4. Adjust the torque to continue opening: After the torque returns to normal, adjust the torque of the electric wrench as needed until the manual valve is fully open.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
