Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-7, an embodiment of the present utility model is provided: a ball cage press cap comprises a ball cage body 1 and a buffer piece 2; the upper end of the ball cage body 1 is connected with a connecting part 22 arranged on the buffer piece 2 through a mounting part 10 arranged on the ball cage body; the surface of the buffer member 2 away from the connecting portion 22 is provided as a concave arc surface, and the cross section of the mounting portion 10 is identical to the cross section of the buffer member 2 for accommodating the buffer member 2.
In summary, when the ball 30 impacts, the buffer 2 is used to buffer the impact, so as to prevent the ball 30 from directly striking the cage 1, so as to reduce the noise generated by the ball 30 and the cage during use; meanwhile, the buffer piece 2 is connected with the mounting part 10 of the ball cage body 1 through the connecting part 22, so that the buffer piece 2 is convenient to mount and dismount, and the buffer piece 2 is convenient to replace; and secondly, the contact area of the connecting part 22 and the mounting part 10 is enlarged, so that the reliable connection between the buffer part 2 and the ball cage 1 is ensured. Based on the above, through the buffer piece 2 at the top of the ball cage body 1, the ball 30 plays a role in buffering when being impacted by high-pressure liquid in the operation of the ball cage valve to strike the top of the ball cage body 1, thereby reducing noise and prolonging the service life of the ball cage valve.
In addition, due to the arrangement of the concave cambered surface, the ball cage can ensure that the ball cage has larger contact surface and more uniform stress when being impacted with the ball 30, and further can avoid the problem that the ball 30 is in direct contact with the ball cage 1 to generate noise.
In a specific implementation, the mounting portion 10 includes a first accommodating area 103 located inside the ball cage 1 and a second accommodating area 101 located outside the ball cage 1, and the first accommodating area 103 and the second accommodating area 101 are communicated through a slot 102.
Further, the connecting portion 22 passes through the first accommodating area 103 and then enters the slot hole 102, and the limiting plate 23 provided on the connecting portion 22 is connected with the second accommodating area 101 in an adaptive manner.
Therefore, the reliable connection of the buffer member 2 and the ball cage 1 is ensured by enlarging the contact area of the buffer member 2 and the ball cage 1. In particular, the two accommodation areas are communicated, so that the limiting plate 23 is convenient to penetrate through the slot hole 102, so that the limiting plate 23 enters the second accommodation area 101, and meanwhile, the two accommodation areas are arranged, so that the buffer element 2 can be fixed, and meanwhile, the space occupation of the buffer element 2 can be reduced. In summary, although this scheme is simple, owing to simple structure, can reduce noise and can reduce the cost of manufacturing and maintenance of valve body simultaneously in extension valve body life.
In addition, the buffer member 2 has large two ends and small middle section, and is clamped in the mounting part 10 after vulcanization, so that the buffer member 2 can not fall off from the ball cage 1 in working impact.
As shown in fig. 2 and fig. 4, in order to improve the connection stability of the buffer member 2 and the ball cage body 1, a limit groove 1031 is further provided on the inner wall surface of the first accommodating area 103, and the limit groove 1031 is connected with the protrusion 21 provided on the buffer member 2 in an adaptive manner.
Further, the number of the limit grooves 1031 is equal to the number of the protrusions 21, and the number of the limit grooves 1031 is plural.
Further, the cross sections of the limiting grooves 1031 and the protrusions 21 are saw-tooth-shaped.
In summary, the protrusions 21 are engaged with the limit grooves 1031, and the protrusions 21 and the limit grooves 1031 are all set to be zigzag, so that the buffer member 2 is tightly attached to the ball cage 1, and is not easy to separate from the ball cage 1, and in particular, the problem that the buffer member 2 falls off due to the impact of the ball 30 on the ball cage 1 in the radial direction can be avoided.
On the basis of the above scheme, since the buffer member 2 is made of elastic material and is integrally formed on the ball cage 1, the gap between the connecting portion 22 and the mounting portion 10 can be minimized, so that the buffer member 2 is more firm and the impact force of the ball 30 can be absorbed by the buffer member 2.
Specifically, the material of the buffer member 2 is rubber, and the buffer member 2 is vulcanized on the ball cage 1. For example, the buffer part 2 is made of polyurethane, so that the buffer effect can be achieved, and meanwhile, the buffer part is wear-resistant, impact-resistant and long in service life.
In summary, the utility model changes the middle of the top of the existing ball cage press cap casting into an elastic buffer piece 2, and through vulcanization, rigid contact with the ball 30 during impact is avoided in work, noise is reduced, damage caused by the impact is reduced, meanwhile, force can be buffered and unloaded, and the ball cage 1 is prevented from being deformed and damaged under the action of force under the long-time impact.
Meanwhile, in the existing production, the problem that the outer threads of the ball cage body 1 are stretched and deformed and the ball cage fixing support is bent due to untimely replacement of the ball cage body 1 after impact deformation and even damage to the ball body 30 and difficult maintenance caused by detachment of the ball cage pressing cap during replacement are solved.
Based on the above, the scheme not only reduces the noise generated by the collision of the ball 30 and the ball cage pressing cap in the working process, but also greatly prolongs the service life of the product and reduces the production and maintenance costs of enterprises.
