Description

Technical Field

[0001] This invention relates to the field of ferrule ball valve technology, specifically a handle locking mechanism and a ferrule ball valve containing the mechanism. Background Technology

[0002] A ferrule ball valve is a type of valve that combines a ferrule connection with a ball valve structure. Its two ends are quickly connected via a ferrule, nut, and fitting body. The internal ball with a circular through-hole rotates to control the flow, shut-off, or regulation of the medium. It has advantages such as convenient installation, reliable sealing, flexible operation, and easy maintenance. The handle installed on the ferrule ball valve is a manual control component used to operate the rotation of the ball inside the valve, and it is usually connected to the valve stem.

[0003] When using existing compression ball valves, the valve opening and closing is controlled by operating the handle. In order to prevent the handle from becoming loose due to vibration, impact or misoperation, a locking mechanism is needed to lock the handle.

[0004] Currently, locking mechanisms typically use a nut for tightening, relying on the friction between the nut and the handle to lock and fix the handle. However, to avoid insufficient friction between the handle and the nut, tools are still needed to tighten the nut, making the locking and unlocking of the handle inconvenient. Furthermore, in some ferrule ball valves, the connection between the handle and the valve stem is exposed to air. When the handle is not in operation for a long time, moisture, dust, and other impurities can easily enter the rotating parts. Especially in humid and corrosive industrial environments, these impurities can react chemically with the valve stem surface, causing corrosion of the rotating parts. This not only increases the resistance to handle rotation but can even prevent the handle from turning altogether. Therefore, this paper proposes a handle locking mechanism and a ferrule ball valve incorporating this mechanism, which eliminates the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Then, the handle body 6 is pushed to rotate around the valve stem 7. At this time, the connecting sleeve 4 is driven by the handle body 6 and the valve stem 7 is driven to rotate synchronously through the fixing bolt, thereby opening the ball valve body 1 and allowing the ball valve body 1 to transport fluid.

A fixing rod 205 is disposed below the movable push block 202. The fixing rod 205 is fixedly connected to the handle body 6. The movable baffle 203 is slidably sleeved on the outer wall of the fixing rod 205. A first spring 201 is sleeved on the outer wall of the fixing rod 205. One end of the first spring 201 contacts the outer wall of the movable baffle 203, and the other end of the first spring 201 contacts the inner wall of the handle body 6. Through the cooperation of the positioning component and the limiting component, the handle body 6 can be easily locked or unlocked.

[0053] In one embodiment, such as Figures 2-4As shown, the sealing assembly includes: a fixing collar 305 fixedly connected to the inner wall of the oil storage assembly 3011; a sealing baffle 3012 is provided on the lower surface of the fixing collar 305; the sealing baffle 3012 is made of fluororubber, which is oil-resistant and temperature-resistant from -40℃ to 150℃; two connecting slide rods 304 are symmetrically fixedly connected to the top of the sealing baffle 3012; both connecting slide rods 304 penetrate into the interior of the oil storage assembly 3011; and a second limiting baffle 301 is fixedly connected to the top of each of the two connecting slide rods 304. 01. The connecting slide rods 304 are slidably connected to the oil storage assembly 3011. The lifting pressure plate 303 and the fixing collar 305 are slidably sleeved on the outer wall of the connecting slide rods 304. The outer walls of the two connecting slide rods 304 are each sleeved with a third spring 302. One end of the third spring 302 is in contact with the outer wall of the second limiting baffle 301, and the other end of the third spring 302 is in contact with the inner wall of the oil storage assembly 3011. Through the cooperation of the fixing collar 305 and the sealing baffle 3012, the leakage of lubricating oil during storage can be avoided.

[0054] In one embodiment, such as Figures 1-7 As shown, the rotating assembly includes: a rotating cylinder 309 disposed at the top of the oil storage assembly 3011, the rotating cylinder 309 being located on one side of the oil delivery conduit 3010, the rotating cylinder 309 penetrating into the interior of the oil storage assembly 3011, a limiting rotating ring integrally formed on the outer wall of the rotating cylinder 309, the rotating cylinder 309 and the limiting rotating ring being rotatably connected to the oil storage assembly 3011, and a lifting push block 308 fixedly connected to the top of the lifting pressure plate 303, the lifting push block 308 penetrating into the interior of the oil storage assembly 3011 and the rotating cylinder 309, the lifting push block 308 being slidably connected to the oil storage assembly 3011 and the rotating cylinder 309;

[0055] A guide assembly is provided on the rotating cylinder 309;

[0056] A locking assembly is provided on the rotating cylinder 309;

[0057] The guiding assembly includes two guide sliders 3015 symmetrically fixedly connected to the inner wall of the rotating cylinder 309. The outer walls of the two guide sliders 3015 are hemispherical. A spiral guide groove 3013 and a straight slide groove 306 are provided at the contact position between the lifting push block 308 and the guide slider 3015 for the guide slider 3015 to slide. An arc-shaped slide groove 3014 is provided at the top of the spiral guide groove 3013 and the straight slide groove 306 for the guide slider 3015 to slide. The inner cavities at both ends of the arc-shaped slide groove 3014 are respectively connected to the inner cavities at the top of the spiral guide groove 3013 and the straight slide groove 306. Through the cooperation of the rotating assembly and the guiding assembly, the lubricating oil can be squeezed and discharged by rotating the rotating cylinder 309.

[0058] In one embodiment, such as Figures 1-4As shown, the locking component is a knurled bolt 307 located at the top of the rotating cylinder 309. The knurled bolt 307 passes through the rotating cylinder 309 to the interior of the oil storage component 3011. The knurled bolt 307 is threadedly connected to the rotating cylinder 309, and the rotating cylinder 309 can be easily fixed by the knurled bolt 307.

[0059] The above embodiment discloses a ferrule ball valve, wherein when fluid needs to be transported, the movable push block 202 is pushed to drive the movable baffle 203 to slide along the outer wall of the fixed rod 205. At this time, the movable baffle 203 is retracted by moving and compressing the first spring 201. At the same time, the movable baffle 203 is separated from the lifting push rod 204 by moving, thereby releasing the limiting obstruction of the lifting push rod 204, thus conveniently releasing the locking and fixing of the handle body 6. Then, the handle body 6 is pushed to rotate around the valve stem 7 as the axis. At this time, the connecting sleeve 4 is driven by the handle body 6, and the valve stem 7 is driven to rotate synchronously by the fixing bolt. At the same time, the limiting slide 207 is driven by the handle body 6 to slide along the inner wall of the fixed sleeve 206, thereby allowing the limiting slide 207 and the fixed sleeve 206 to move together. During the separation process, the positioning block 208, blocked by the inner wall of the fixed sleeve 206, pushes the first limiting baffle 209 to slide along the inner wall of the limiting slide cylinder 207. At this time, the lifting push rod 204 slides along the inner wall of the handle body 6 under the push of the first limiting baffle 209. Meanwhile, the first limiting baffle 209 contracts by moving and squeezing the second spring 2010, and then releases the moving push block 202. At this time, the first spring 201 can push the moving baffle 203 to automatically reset by rebounding, thereby opening the ball valve body 1 and allowing the ball valve body 1 to transport fluid. When it is necessary to stop the transport of fluid, the moving push block 202 is pushed to separate the moving baffle 203 from the lifting push rod 204. Then, the handle body 6 is pushed to rotate and reset, thereby conveniently locking and fixing the handle body 6.

[0060] When periodic lubrication is required at the rotating position of the valve stem 7 and the fixed sleeve 5, the knurled bolt 307 is rotated upwards, thereby separating the knurled bolt 307 from the oil reservoir assembly 3011 and releasing the locking and fixing of the rotating cylinder 309. The rotating cylinder 309 then rotates along the inner wall of the oil reservoir assembly 3011 via the limiting ring. Simultaneously, the guide slider 3015, driven by the rotating cylinder 309, presses against the inner wall of the spiral guide groove 3013. At this time, the lifting push block 308, pushed by the spiral guide groove 3013 and the pressing force of the guide slider 3015's outer wall, pushes the lifting pressure plate 303 downwards along the outer wall of the connecting slide rod 304. Simultaneously, the oil reservoir assembly 3011's inner cavity... The lubricating oil is pressed by the lifting pressure plate 303, which applies pressure to the upper surface of the sealing baffle 3012. At this time, the sealing baffle 3012 separates from the lower surface of the fixing sleeve 305 under the pressure of the lubricating oil. Meanwhile, the second limiting baffle 301 slides along the inner wall of the oil storage component 3011 through the connecting slide rod 304 driven by the sealing baffle 3012, and compresses the third spring 302 to contract. At this time, the lubricating oil moves to the lower part of the sealing baffle 3012 through the gap between the fixing sleeve 305 and the sealing baffle 3012, and then passes through the oil drain hole 3016 and the guide groove in sequence to deliver the lubricating oil to the outer wall of the valve stem 7, so as to lubricate the position where the valve stem 7 and the fixing sleeve 5 meet.

[0061] When lubrication of valve stem 7 is completed, the third spring 302 pushes the second limit baffle 301 to reset by rebounding, thereby allowing the sealing baffle 3012 to seal the port of the fixed collar 305. Then, the rotating cylinder 309 is rotated to reset, and the guide slider 3015 slides along the inner wall of the arc-shaped slide groove 3014 under the drive of the rotating cylinder 309 until the guide slider 3015 contacts the inner wall of the straight slide groove 306. Then, the knurled bolt 307 is rotated and inserted into the oil reservoir assembly 301. Inside 1, the rotating cylinder 309 can be locked and fixed. Then, lubricating oil is delivered to the inner cavity of the oil storage component 3011 through the oil delivery pipe 3010. At this time, the lifting pressure plate 303 pushes the lifting push block 308 to rise along the inner wall of the oil storage component 3011 and the rotating cylinder 309 under the pressure of the lubricating oil. At this time, the lifting push block 308 slides along the outer wall of the guide slider 3015 through the linear slide groove 306, so that the lubricating oil can be conveniently stored and the valve stem 7 can be lubricated periodically.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
