Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples: referring to a ball valve rod with a protection structure shown in fig. 1, the ball valve rod comprises a valve rod 1, a mounting plate 8 is fixed at the bottom of the valve rod, a rectangular driving block 2 is movably mounted at the bottom of the mounting plate 8, the rectangular driving block 2 is matched with a slot 4 arranged at the upper end of a spherical valve core 3, and when fluid in a pipeline impacts the outer surface of the spherical valve core 3, the spherical valve core 3 drives the rectangular driving block 2 to move.
When fluid in a pipeline impacts the outer surface of the spherical valve core 3, the spherical valve core 3 drives the rectangular driving block 2 to move, the rectangular driving block 2 is movably connected with the valve rod 1, the rectangular driving block 2 does not drive the valve rod 1 to move, namely, impact cannot be caused on the valve rod 1, and the valve rod 1 can be effectively protected.
As a preferred implementation manner in this embodiment, as shown in fig. 2, the rectangular driving block 2 is located in a groove 5 provided at the bottom of the mounting plate 8, the rectangular driving block 2 is slidably penetrated by a plurality of limiting rods 6, two ends of the limiting rods 6 are fixedly installed in the groove 5, and movable gaps are provided between the front and rear ends of the rectangular driving block 2 and the inner walls of the groove.
This ball valve case 3 of ball valve is pegged graft with valve rod 1 and is installed, rectangular drive piece 2 is pegged graft with recess 5 promptly, accessible rotatory valve rod 1 drives ball valve case 3 rotatory, open and shut operation of pipeline, when the pipeline is closed fast, as shown in fig. 3, because there is the water hammer phenomenon, its ball valve case 3 will receive left side rivers collision effect, and because rectangular drive piece 2 adopts sliding connection with valve rod 1, ball valve case 3 will take place the horizontal migration together for valve rod 1 with drive rectangular drive piece 2, ball valve case 3 bumps the buffering through the inside elasticity sealing ring that sets up of extrusion ball valve, in the whole in-process, the valve rod does not contact with rectangular drive piece 2, consequently, valve rod 1 does not receive impact force effect, can effectively realize the protection to valve rod 1.
It should be noted that the valve rod 1 is inserted and mounted with the ball valve core 3 through the rectangular driving block 2, so as to facilitate the assembly of the two.
All the cover is equipped with two buffer springs 7 on every gag lever post 6, and two buffer springs 7 are located the both sides of rectangle drive piece 2 respectively, when ball valve case 3 received impact motion, ball valve case 3 bumps the buffering through the inside elastic sealing ring that sets up of extrusion ball valve, bump the buffering through compression buffer spring 7 simultaneously, can avoid ball valve case and elastic sealing ring to take place violently to collide and lead to elastic sealing ring to damage and produce crackle or elastic sealing ring to take place irreversible deformation, improve the life of ball valve, after the collision is accomplished, through buffer spring 7's elasticity effect, rectangle drive piece 2 resumes the normal position.
It should be noted that the buffer springs 7 are disposed on both sides of the rectangular driving block 2, so that the impact force can be buffered by the buffer springs 7 when the valve rod 1 rotates to any side for closing the valve.
As a preferred implementation manner in this embodiment, as shown in fig. 2, the groove 5 is provided with a square or rectangular structure, and the left and right end surfaces of the rectangular driving block 2 are in sliding contact with the inner wall of the groove 5, so that friction is reduced, and meanwhile, the contact surface can distribute force, so that excessive distribution is avoided to act on the limit rod 6 when the valve rod 1 is rotated, and deformation damage to the limit rod 6 is caused.
