Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-self-aggregation ball valve. Background Art

[0002] A ball valve is a type of valve. It is a valve in which the ball is directly driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into: pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] However, the above and other typical existing technologies still have certain problems when used:

[0004] During actual use of the current three-way ball valve, the ball itself is affected by the fluid inside the valve body and is prone to deflect in one direction, causing the ball to rotate inside the valve body. In addition, during actual use of the current three-way ball valve, at the moment the ball closes the valve pipe, the flow effect of the fluid will be blocked, and a large stress will occur in an instant, causing the valve body to move.

Example

[0026] On the basis of the first embodiment, Figure 3-5As shown, the locking mechanism 5 includes a locking shaft 501, an insert rod 502, two groups of springs 503, two groups of first slide rails 504, a first support rod 505, a second support rod 506, a pressing block 507 and two groups of second slide rails 508. The inner surface of the insert rod 502 and the outer wall of the locking shaft 501 are mutually clamped, and the left and right sides of the two groups of insert rods 502 are slidably connected to the first slide rail 504 through the slide rod, and the spring 503 is located on the inner side of the first slide rail 504, the insert rod 502 is elastically connected to the first slide rail 504 through the spring 503, the first support rod 505 is movably connected to the side of the insert rod 502 away from the locking shaft 501, one end of the first support rod 505 is movably connected to the second support rod 506, the pressing block 507 is fixedly connected to the top end of the second support rod 506, and the top end of the second support rod 506 is slidably connected to the second slide rail 508 through the slide rod. The lock shaft 501 is fixedly connected to the center position of the bottom of the three-way ball valve 2, and the axis lines of the lock shaft 501 and the connecting rod 3 coincide with each other. The outer shape of the plug rod 502 is C-shaped. The two sets of first slide rails 504 are fixedly connected to the bottom surface of the three-way valve body 1, and the two sets of second slide rails 508 are fixedly connected to the back of the three-way valve body 1. The direction of the second slide rail 508 forms a certain oblique angle with the horizontal section of the three-way valve body 1, and the lock shaft 501 is movably connected to the bottom of the three-way valve body 1 through a sealing gasket.

[0027] When in use, the utility model anti-self-aggregation ball valve, in normal operation, the plug rod 502 can achieve elastic resistance with the first slide rail 504 under the action of the spring 503, thereby achieving the connection with the lock shaft 501, and the lock shaft 501 is fixed to the bottom of the three-way ball valve 2. In this way, the locking effect can effectively prevent the three-way ball valve 2 from rotating. When the docking position of the three-way ball valve 2 needs to be changed, the pressing block 507 can be pushed downward to drive the second support rod 506 to move obliquely downward under the stable sliding of the second slide rail 508. In this process, it can resist the first support rod 505 to swing, and one end of the first support rod 505 is movably connected to the plug rod 502, so that the plug rod 502 can have a sliding effect on the inner side of the first slide rail 504, so that it is separated from the lock shaft 501, and the adjustment handle 4 can be turned to complete the toggle operation of the three-way ball valve 2. Example

[0028] On the basis of the first embodiment, Figure 1-2 As shown, the flow reduction mechanism 6 includes an insert 601, a sealing sleeve 602, six groups of gaskets 603 and a flow reduction net 604. The sealing sleeve 602 is plugged into one end of the insert 601, and the gasket 603 is plugged into the insert 601. The insert 601 is plugged into the three-way valve body 1, and the outer surface of the insert 601 is spline-shaped. The flow reduction net 604 is located in the middle of adjacent gaskets 603, and multiple groups of flow reduction nets 604 are distributed opposite to each other. The diameters of the gaskets 603 and the flow reduction net 604 match the inner diameter of the insert 601.

[0029] During specific use, the anti-self-aggregation ball valve of the utility model, during normal circulation, the fluid flows through the surface of multiple groups of flow-reducing nets 604 on the inner side of the insert sleeve 601, and when the three-way ball valve 2 changes direction, the pipeline is closed, and the fluid will have an instantaneous force, and the force is blocked by the oppositely distributed flow-reducing nets 604, so that the flow rate of the fluid and the force are reduced, and the insert sleeve 601 is plugged into the pipe mouth of the three-way valve body 1, and sealed by the sealing sleeve gasket 602, so that the insert sleeve 601 can be easily removed and the internal gasket ring 603 and the flow-reducing net 604 can be replaced and maintained.

[0030] Working principle: First, during normal operation, the plug rod 502 in the locking mechanism 5 directly plugs and locks the lock shaft 501, and the lock shaft 501 is fixed at the bottom of the three-way ball valve 2, which can effectively prevent the three-way ball valve 2 from deflecting inside the three-way valve body 1. On the other hand, during the process of fluid flowing into the three-way valve body 1, it is decelerated by the flow reduction net 604 between several groups of gaskets 603 in the flow reduction mechanism 6, and the overall flow direction of the liquid presents a bow shape inside the plug tube 601. When the flow channel needs to be changed, the pressing block 507 is pushed downward to achieve an oblique downward movement effect under the limit of the second slide rail 508, and at the same time drive the second support rod 506 to swing downward, and the second support rod 506 is movably connected to the first support rod 505, and the first support rod 505 is movable on one end of the insertion rod 502, so that the insertion rod 502 is forced to move to one side, squeezing the spring 503 in the first slide rail 504 and separating it from the lock shaft 501, and then the adjustment handle 4 at the top of the connecting rod 3 can be turned to turn the three-way ball valve 2. When the three-way ball valve 2 is turned to ninety degrees, the pipeline is suddenly closed. Due to the effect of multiple groups of oppositely distributed flow reduction nets 604, the fluid effectively reduces the movement of the three-way valve body 1, ensuring better stability. Finally, a sealing sleeve 602 is set at one end of the insert sleeve 601, so that it can be better connected with the external pipeline and provide a sealing effect.
