Abstract
Description
Technical Field
[0001] This utility model relates to the field of low torque ball valve technology, and in particular to a quick-release low torque ball valve. Background Technology
[0002] A ball valve's opening and closing element is a perforated sphere. The ball rotates 0-90° around the valve stem axis, opening or closing the valve. Ball valves have many uses, generally for switching on / off or regulating media in pipelines; they are most commonly used in heating and air conditioning water systems and water supply pipelines.
[0003] A low-torque ball valve, with announcement number CN222277538U, specifically relates to the field of ball valve technology. It includes a valve body with a movably mounted spherical valve core on its inner side and threaded ends at both ends. A valve stem protection device is located on the upper inner side of the valve body to prevent valve stem wear and enhance sealing, preventing overflow. The valve stem protection device includes a valve stem movably mounted on the inner upper side of the valve body, with its lower end fixedly connected to the upper end of the ball valve. An H-shaped groove is formed on the outer surface of the lower end of the valve stem, and a rotating disk is fixedly mounted on the upper end of the valve stem. A ball valve anti-wear device is also located on the inner side of the valve body to prevent wear caused by friction between the outer surface of the spherical valve core and the threaded end ports. This invention, by including a valve stem protection device, helps prevent valve stem wear and enhances sealing, preventing overflow. The ball valve anti-wear device also helps prevent wear caused by friction between the outer surface of the spherical valve core and the threaded end ports.
[0004] While the aforementioned low-torque ball valve can prevent wear caused by friction between the outer surface of the ball valve core and the threaded end port through the ball valve anti-wear device, it does not take into account that although the device can reduce wear, wear will still inevitably occur after long-term use. When the wear reaches a certain level, some parts of the device need to be replaced. However, the aforementioned device does not have a mechanism for easy disassembly by operators, which makes it more troublesome for operators to maintain and replace the device, thus reducing the maintenance efficiency of the device.
[0005] Therefore, a low-torque ball valve is proposed, which can be achieved through a ball valve anti-wear device. Utility Model Content
[0006] The purpose of this invention is to provide a quick-release low-torque ball valve, which can solve the problem of low maintenance efficiency in some devices.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-release low-torque ball valve, comprising a ball valve pump body, wherein a ball valve is rotatably mounted inside the ball valve pump body, and connecting pipes are fixedly mounted on both the left and right sides of the ball valve pump body and communicate with the interior of the ball valve pump body. The connecting pipes have connecting threaded grooves inside, and the ball valve has a through port inside. A disassembly box is fixedly mounted on the top of the ball valve pump body, and a connecting rod is provided above the ball valve pump body. A handle is fixedly mounted on one end of the connecting rod. A quick-release mechanism is provided on the disassembly box, and the quick-release mechanism includes a threaded rod rotatably mounted inside the disassembly box.
[0008] Preferably, the quick-release mechanism further includes a knob, a through groove, a threaded connecting block, a connecting plate, an auxiliary support plate, a limiting plate, and a movable groove. One end of the threaded rod extends to the outside of the disassembly box and is fixedly installed with a knob. A threaded connecting block is threaded onto the threaded rod. A through groove is provided on one side of the disassembly box. A connecting plate is fixedly installed on one side of the threaded connecting block. One side of the connecting plate extends to the outside of the disassembly box through the through groove. An auxiliary support plate is fixedly installed on the connecting plate. A limiting plate is fixedly installed on one side of the connecting plate, and a movable groove is provided on the limiting plate.
[0009] Preferably, a connecting block is fixedly installed on the top of the ball valve pump body, one end of the connecting block extends to the outside of the ball valve pump body, an O-ring is fixedly installed on the top of the ball valve pump body, and a rubber ring is fixedly installed inside the O-ring.
[0010] Preferably, a connecting plate is rotatably mounted inside the O-ring connecting block, a polygonal connecting rod is fixedly mounted on the bottom of the connecting plate, a polygonal groove with a shape matching the polygonal connecting rod is opened on the connecting block, one end of the polygonal connecting rod extends into the interior of the polygonal groove, and the top of the connecting plate is fixedly connected to the other end of the connecting rod.
[0011] Preferably, a protective cover is hinged to the top of the disassembly box.
[0012] Preferably, an anti-collision rubber ring is fixedly installed inside the connecting pipe.
[0013] Preferably, the inner wall of the ball valve pump body is fixedly equipped with two sets of rubber layers distributed vertically.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) The quick-release low-torque ball valve, through the combination of threaded rod, knob, through groove, threaded connecting block, connecting plate, auxiliary support plate, limit plate and movable groove, enables the device to rotate by controlling the knob to drive the limit plate to move longitudinally, thereby enabling the operator to disassemble and replace it by holding the friction layer and driving the connecting plate and polygonal connecting rod to move longitudinally and laterally, thus optimizing the disassembly steps of the device and improving the maintenance efficiency of the device.
[0016] (2) The quick-release low-torque ball valve, through the combined use of rubber layer, rubber ring and anti-collision rubber ring, can reduce the friction between the ball valve and the O-ring and the inner wall of the ball valve pump body when the ball valve and the connecting plate rotate, thereby reducing the wear of the device and improving the service life of the device to a certain extent. The anti-collision rubber ring can prevent the pipe from being directly disconnected from the ball valve when the device is connected to the pipeline, which would cause the ball valve to wear further during rotation and improve the service life of the device.

Detailed Implementation
[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a quick-release low-torque ball valve, including a ball valve pump body 1. A ball valve 12 is rotatably mounted inside the ball valve pump body 1. Connecting pipes 2 are fixedly mounted on both the left and right sides of the ball valve pump body 1, and the connecting pipes 2 communicate with the interior of the ball valve pump body 1. A connecting threaded groove 13 is opened inside the connecting pipe 2. A through port is opened inside the ball valve 12. A disassembly box 3 is fixedly mounted on the top of the ball valve pump body 1. A connecting rod 7 is provided above the ball valve pump body 1. A handle 9 is fixedly mounted on one end of the connecting rod 7. A quick-release mechanism 8 is provided on the disassembly box 3. The quick-release mechanism 8 includes a threaded rod 801 rotatably mounted inside the disassembly box 3, a knob 802, a through groove 803, a threaded connecting block 804, a connecting plate 805, an auxiliary support plate 806, a limiting plate 807, and a movable groove 808. A connecting... Connecting block 14 has one end extending to the outside of ball valve pump body 1. An O-ring 5 is fixedly installed on the top of ball valve pump body 1. A rubber ring 16 is fixedly installed inside the O-ring 5. A connecting plate 6 is rotatably installed inside the O-ring 5. A polygonal connecting rod 15 is fixedly installed at the bottom of the connecting plate 6. A polygonal groove matching the shape of the polygonal connecting rod 15 is opened on the connecting block 14. One end of the polygonal connecting rod 15 extends into the polygonal groove. The top of the connecting plate 6 is fixedly connected to the other end of the connecting rod 7. This allows the device to rotate via the control knob 802, driving the limiting plate 807 to move longitudinally. This enables the operator to disassemble and replace the friction layer 10 by gripping it and moving the connecting plate 6 and the polygonal connecting rod 15 longitudinally and laterally, optimizing the disassembly process and improving maintenance efficiency.
[0025] like Figure 1 As shown, a protective cover 4 is hinged to the top of the disassembly box 3. The protective cover 4 can prevent the operator from accidentally touching the knob 802, which would cause the device to become loose, thus improving the stability of the device to a certain extent.
[0026] like Figure 3 and Figure 4As shown, a rubber ring 16 is fixedly installed inside the O-ring 5, and an anti-collision rubber ring 17 is fixedly installed inside the connecting pipe 2. Two sets of rubber layers 11 are fixedly installed on the inner wall of the ball valve pump body 1 and are distributed vertically. This reduces the friction between the ball valve 12 and the inner wall of the O-ring 5 and the ball valve pump body 1 when the ball valve 12 rotates with the connecting disc 6, thereby reducing the wear of the device and improving its service life to a certain extent. The anti-collision rubber ring 17 prevents the pipe from being directly disconnected from the ball valve 12 when the device is connected to the pipe, which would cause further wear on the ball valve 12 during rotation and improve the service life of the device.
[0027] Working Principle: During use, the pipe is threaded into the connecting pipe via a threaded groove inside the connecting pipe. The anti-collision rubber ring creates a barrier between the pipe and the ball valve when connected to the device, preventing direct contact and potential damage due to friction during ball valve rotation. To close the valve, the operator grips the friction layer, rotating the handle to turn the ball valve, thus blocking the internal passage and isolating transmission. Conversely, rotating the handle in the opposite direction opens the passage between the ball valve and the pipe, allowing transmission. The rubber layer reduces friction between the ball valve and the pump body's inner wall as it rotates, improving control and reducing wear, thus extending the device's lifespan. The handle rotation, via the connecting rod... The device is designed to rotate the connecting disc inside the O-ring. A rubber ring inside the O-ring reduces friction during rotation, allowing for easier control and reducing torque. After prolonged rotation, wear on the connecting disc can be removed by lifting the protective cover and rotating a knob. This knob rotates the threaded rod, causing the threaded connecting block to move longitudinally. The connecting block then moves the limiting plate longitudinally, freeing it from fixing the connecting disc. Once the limiting plate reaches the desired height, the connecting disc can be lifted by gripping the friction layer, detaching it from the O-ring and the polygonal connecting rod. A movable groove allows the operator to grip the friction layer and move the connecting disc and polygonal connecting rod laterally for easy disassembly and maintenance.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
