Drawings
FIG. 1 is the structure schematic diagram of the upper assembling type ball valve seat structure of the on-line maintenance.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In the attached figure 1, the on-line maintenance upper-mounted ball valve seat structure comprises a valve body 1 with a step structure, a valve seat 2, a sealing ring 3, a ball body 4, a pressure spring 5, a valve seat support 6, a half open ring 7 and a fan-shaped locking block 8.
The valve body 1 is provided with a first step 11, a second step 12 and a third step 13 from bottom to top in sequence. The valve seat support 6 is arranged between the third step 13 and the valve seat 2 in a pressing mode, a clamping groove 61 is arranged at the top end of the valve seat support 6, and the half-open ring 7 is in compression joint with the clamping groove 61. A semi-open ring 7 is pressed between the fan-shaped locking block 8 and the valve seat support 6, a pressure spring 5 is pressed between the valve seat support 6 and the valve seat 2, and a sealing ring 3 is pressed between the valve seat 2 and the ball 4. One end of the valve seat 2 is provided with a connecting screw hole 26 and a slotted hole 24, and the ball 4 is connected with the slotted hole 24 in a sealing way through the sealing ring 3.
The sector lock block 8 is provided with a pressing head 81 and a through hole 82. Ram 81 is crimped to semi-open ring 7. The valve seat support 6 is provided with a threaded through hole 63, and the threaded through hole 63 is fixedly connected with the through hole 82 through the hexagon socket head cap screw 9. A blind hole 62 is arranged at the lower side of the threaded through hole 63, and the pressure spring 5 is in compression joint with the blind hole 62.
An annular groove 21 is formed in the valve seat 2 near the second step 12. The annular groove 21 is sealingly connected to the second step 12 by an O-ring. The valve seat 2 is provided with an L-shaped through hole 22. One end of the L-shaped through hole 22 is disposed near the first step 11, and the other end of the L-shaped through hole 22 abuts the ball 4.
When the valve is installed, the valve seat component and the valve seat support 6 are assembled together, then the fan-shaped locking block 8 is reversely arranged on the valve seat support 6, then the combined component is arranged in the valve body 1, and tools similar to a push rod are used for pushing the fan-shaped locking blocks 8 at the two ends, so that the component is wholly pushed into the valve body 1. And taking down the tool, placing the ball body 4 positioned at the open position into the valve body 1, rotating the ball body 4 to a closed state after being installed, pulling the valve seat assembly towards the ball body 4 by using the tool, then installing the semi-open ring 7 into the clamping groove of the valve seat support 6, and detaching the fan-shaped locking block 8, wherein the fan-shaped locking block is installed in the direction shown in the attached drawing 1. When needing the dismouting on being in the pipeline, pull down fan-shaped locking piece 8 earlier and turn over the dress, take off half ring-opening 7, utilize the frock with the disk seat sub-assembly push valve body 1 inside, spheroid 4 alright take out to realize quick online dismouting function.
When the valve breaks down on the pipeline and needs to be repaired, the valve does not need to be disassembled from the pipeline, only the stud and the nut of the middle flange need to be disassembled, the valve cover and the valve rod assembly are taken down from the valve body together, and then the ball body and the valve seat assembly are taken out, so that the ball body and the valve seat can be repaired on line. This maintenance saves time and minimizes losses in production.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
