Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to fig. 1: the fluorine lining ball valve in the embodiment 1 comprises a valve body 1, a valve seat 11, a valve rod 12 and a valve ball 2, wherein the valve ball 2 is fixedly connected with the valve rod 12, the valve seat 11 and the valve ball 2 are positioned in the valve body 1, the valve seat 11 and the valve ball 2 are in sealing fit with each other, the valve ball 2 comprises a fixing support 21 and a polytetrafluoroethylene ball piece 22, the fixing support 21 is fixedly connected with the valve rod 12, one side of the fixing support 21 is detachably and fixedly connected with the polytetrafluoroethylene ball piece 22, and the polytetrafluoroethylene ball piece 22 is in sealing contact with the valve seat 11. The detachable fixed connection is a bolt connection or a buckle connection.
Working principle: valve rod 12 drives fixed bolster 21 to rotate and opens and close the valve, when polytetrafluoroethylene ball piece 22 rotates to the left side, polytetrafluoroethylene ball piece 22 and disk seat 11 sealing fit realize the complete closure of valve, when polytetrafluoroethylene ball piece 22 rotates 90 degrees to valve front side or rear side, realize the complete opening of valve, fluid can flow through from the through-hole at fixed bolster 21 center, when polytetrafluoroethylene ball piece 22 damages, can dismantle the valve after, rotate polytetrafluoroethylene ball piece 22 to the valve right side, then carry out dismouting operation to it. Because the valve ball 2 adopts the split structure that the polytetrafluoroethylene ball piece 22 and the fixed bracket 21 are combined, the weight and the manufacturing cost of the valve ball 2 are reduced, the polytetrafluoroethylene ball piece 22 has good tightness when contacting the metal valve seat 11, the service life is long, the sealing surface of the metal valve seat 11 is not easy to wear, the cost for replacing and repairing the damaged polytetrafluoroethylene ball piece 22 is low, and the fixed bracket 21 can be reused.
In embodiment 2, on the basis of embodiment 1, the upper and lower ends of the fixing support 21 are provided with telescopic cylinders 3, a fixing plate 23 is connected between the telescopic ends of the upper and lower telescopic cylinders 3, and the telescopic cylinders 3 have a limiting function. The fixing plate 23 is in bolt connection with the polytetrafluoroethylene ball piece 22, so that the polytetrafluoroethylene ball piece 22 is convenient to disassemble and assemble. An elastic supporting pad 24 is arranged between the fixed plate 23 and the fixed bracket 21. The telescopic cylinder 3 can firmly mount the fixed plate 23, move stably and bear even force, the elastic support pad 24 can fill the gap between the fixed plate 23 and the fixed bracket 21, so that the assembly is more compact, the impact resistance of the valve ball is improved, and the elastic support pad 24 can also improve the sealing performance of the polytetrafluoroethylene ball piece 22 contacted with the valve seat 11.
Embodiment 3, on the basis of embodiment 2, the telescopic cylinder 3 includes a cylinder body 31, a piston rod 32 and a piston body 33, two sides of the piston body 33 are provided with an elastic cushion 34 and a supporting spring 35, and two ends of the piston rod 32 are respectively and fixedly connected with the fixing plate 23 and the piston body 33. The elastic force of the supporting spring 35 can act on the piston body 33 and the piston rod 32 to strengthen the sealing pre-tightening force of the polytetrafluoroethylene ball 22. The thickness of the elastic cushion 34 can adjust the stroke of the piston body 33, so that the assembly is more compact and is not easy to loosen.
In example 4, on the basis of example 3, a communicating pipe 36 is connected between the upper and lower cylinders 31, the communicating pipe 36 is connected with a pressure tank 37, and a certain gas can be pre-charged into the cylinders 31 through the pressure tank 37, so that the cylinders 31 have a certain gas pressure, and the gas pressure acts on the piston body 33, so that the polytetrafluoroethylene ball 22 has a durable sealing pre-tightening force, and when the valve is closed, the higher the gas pressure is, the stronger the sealing performance of the valve is.
