Detailed Description

The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Referring to fig. 1 and 2, fig. 1 is a schematic view of a floating ball valve seat according to an embodiment of the present invention, and fig. 2 is a cross-sectional view of the floating ball valve seat according to an embodiment of the present invention.

As shown, a floating ball valve seat schematic includes: the sealing seat body 10, the sealing seat body 10 includes the bayonet sleeve part 20 and the sealing cone part 30 located at the other end of the bayonet sleeve part 20, the sealing cone part 30 has the first cone part 31 and the second cone part 32; the flange reinforcing seat 40 is arranged in the sealing seat body 10, the flange reinforcing seat 40 comprises a reinforcing base 41 and a penetrating seat 42, the clamping sleeve part 20 is sleeved on the penetrating seat 42, and the sealing seat body 10 is abutted against the reinforcing base 41; and the buffer rubber ring 50 is positioned at the other side of the flange reinforcing seat 40.

In the present novel embodiment of the experiment, the flange reinforcing base 40 is made of copper, the ferrule portion 20 is sleeved on the penetrating base 42, and the sealing seat 10 abuts on the reinforcing base 41. Preferably, the outer diameter of the piercing seat 42 is 1.0mm to 1.5mm larger than the inner diameter of the ferrule portion 20 so that the ferrule portion 20 can be securely nested on the piercing seat 42. The arrangement of the penetrating seat 42 can prevent the debris and foreign matters from entering the pipeline, and meanwhile, the reinforcing base 41 of the flange reinforcing seat 40 and the penetrating seat 42 reinforce the support of the sealing seat body 10, so that the sealing seat body 10 is prevented from loosening after long-time impact, and the sealing stability is enhanced.

Further, the sealing cone portion 30 is provided with a first cone portion 31 and a second cone portion 32, wherein the taper of the first cone portion 31 is larger than that of the second cone portion 32. The top end of the punch-out seat 42 has a taper which is consistent with the taper of the second tapered part 32. When the ball body is abutted against the sealing taper part 30, better fit can be obtained, and the sealing performance is better.

It is worth mentioning that the other side of the flange reinforcing seat 40 is provided with the buffering rubber ring 50, the outer rings of the sealing seat body 10, the flange reinforcing seat 40 and the buffering rubber ring 50 are provided with limiting notches 60 corresponding to each other in position, and the number of the limiting notches 60 is set to 4 groups arranged in an array. When the ball valve is installed, the buffering rubber ring 50 can make the installation of the ball valve more stable and prevent loosening, and meanwhile, the limiting notch 60 can also prevent the sealing seat body 10, the flange reinforcing seat 40 and the buffering rubber ring 50 from rotating, so that the installation stability of the ball valve is greatly improved, namely, the sealing stability is improved.

The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art.
