Description

Technical Field

[0001] The invention relates to the technical field of ferrule ball valves, in particular to a handle locking mechanism and a ferrule ball valve containing the mechanism. Background Art

[0002] A ferrule ball valve is a valve that combines a ferrule connection method with a ball valve structure. Its two ends are quickly connected through a ferrule, a nut and a joint body. The ball with a circular through hole rotates inside to control the flow, cutoff or adjustment of the medium. It has the advantages of easy 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 is usually connected to the valve stem.

[0003] When the existing ferrule ball valve is in use, the opening and closing of the valve is controlled by an operating handle. In order to prevent the handle from loosening due to vibration, impact or misoperation, the handle needs to be locked by a locking mechanism.

[0004] At present, the locking mechanism usually adopts the method of nut compression, and the handle is locked and fixed by the friction between the nut and the handle. However, in order to avoid insufficient friction between the handle and the nut, it is still necessary to use tools to tighten the nut, which makes the locking and unlocking operations of the handle more inconvenient. At the same time, the connection between the handle and the valve stem of some ferrule ball valves is exposed to the air. When the handle is in a non-operating state for a long time, impurities such as water vapor and dust can easily enter the rotating part, especially in a humid and highly corrosive industrial environment. These impurities will react chemically with the surface of the valve stem, causing rust on the rotating part of the valve stem, which will not only increase the resistance to the rotation of the handle, but in severe cases it will even cause the handle to be unable to rotate. Based on this, a handle locking mechanism and a ferrule ball valve containing the mechanism are now provided, which can eliminate the disadvantages of the existing device. Summary of the Invention

[0026] The above embodiment discloses a ferrule ball valve, in which, when it is necessary to transport the fluid, 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 contracted by moving and squeezing the first spring 201. At the same time, the movable baffle 203 is separated from the lifting push rod 204 by movement, thereby releasing the limit blockage of the lifting push rod 204, thereby conveniently releasing the locking fixation of the handle body 6. Thereafter, the handle body 6 is pushed to rotate with the valve stem 7 as the axis. At this time, the connecting sleeve 4 is driven by the handle body 6 and drives the valve stem 7 to rotate synchronously through 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 be mutually locked. Separation, during this process, the positioning block 208 is blocked by the inner wall of the fixed sleeve 206, pushing the first limit baffle 209 to slide along the inner wall of the limit slide 207.

At the same time, the first limit baffle 209 contracts by moving and squeezing the second spring 2010, and then the moving push block 202 is released. At this time, the first spring 201 can push the moving baffle 203 to automatically reset by rebounding, so that the ball valve body 1 can be opened, so that the ball valve body 1 can convey the fluid. When it is necessary to stop conveying the fluid, the moving push block 202 is pushed to separate the moving baffle 203 and the lifting push rod 204 from each other, and then the handle body 6 is pushed to rotate and reset, so that the handle body 6 can be conveniently locked and fixed; When it is necessary to lubricate the rotation position of the valve stem 7 and the fixed sleeve 5 regularly, the knurled bolt 307 is rotated to rise, so that the knurled bolt 307 and the oil storage component 3011 can be separated from each other, thereby releasing the locking fixation of the rotating cylinder 309, and then the rotating cylinder 309 is rotated. At this time, the rotating cylinder 309 rotates along the inner wall of the oil storage component 3011 through the limiting swivel, and at the same time, the guide slider 3015 is driven by the rotating cylinder 309 to squeeze the inner wall of the spiral guide groove 3013.

At this time, the sealing baffle 3012 is separated from the lower surface of the fixed collar 305 under the squeeze of the lubricating oil. At the same time, the second limiting baffle 301 slides along the inner wall of the oil storage assembly 3011 through the connecting slide rod 304 and is driven by the sealing baffle 3012, and squeezes the third spring 302 to shrink. At this time, the lubricating oil passes through the gap between the fixed collar 305 and the sealing baffle 3012 and moves to the bottom of the sealing baffle 3012. Thereafter, the lubricating oil is sequentially delivered to the outer wall of the valve stem 7 through the oil discharge hole 3016 and the guide groove, thereby lubricating the joint position of the valve stem 7 and the fixed sleeve 5. When the lubrication of the valve stem 7 is completed, the third spring 302 pushes the second limit baffle 301 to reset by rebounding, so that the sealing baffle 3012 can seal the port of the fixed collar 305. Then the rotating cylinder 309 is rotated to reset. At the same time, the guide slider 3015 is driven by the rotating cylinder 309 to slide along the inner wall of the arc-shaped slide groove 3014 until the guide slider 3015 contacts the inner wall of the linear slide groove 306. Then the knurled bolt 307 is rotated to insert it into the oil storage assembly 301. 1, thereby locking and fixing the rotating cylinder 309, and then delivering lubricating oil to the inner cavity of the oil storage component 3011 through the oil delivery conduit 3010. At this time, the lifting and lowering pressure plate 303 pushes the lifting and lowering push block 308 to rise along the inner wall of the oil storage component 3011 and the rotating cylinder 309 under the squeezing and pushing of the lubricating oil. At this time, the lifting and lowering 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 regularly.
