Fig. 2 is a schematic cross-sectional view at a in fig. 1.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the high-temperature high-pressure wear-resistant ball valve with good sealing effect comprises a valve body 1, wherein a ball core 2 is arranged in the valve body, a middle cavity 3 is formed between the ball core and the inner wall of the top of the valve body, the valve body comprises a left valve body 11 and a right valve body 12, and an accommodating groove 4 is formed in the opposite surfaces of the left valve body and the right valve body; the accommodating grooves comprise vertical grooves 41 and transverse grooves 42, and the transverse grooves are arranged corresponding to the accommodating grooves; still include sealed pad 5, sealed pad includes bottom ring 51 and flange 52, the flange with erect the sealed cooperation of groove both sides inner wall, the bottom ring is located when being used for the pressurized in the horizontal groove with horizontal groove top inner wall sealed cooperation. This horizontal groove corresponds the setting with the lumen, and under conventional pressure, sealed the pad can not change, and when medium pressure was too big, the lumen pressure leaked the horizontal inslot, promoted sealed pad bottom and rises, and the end ring up end closely cooperates with horizontal groove top inner wall, prevents to leak.
In this embodiment, as shown in fig. 2, the inner wall of the top of the transverse groove is an inclined structure with a high middle part and two low ends. Referring to the thickened part in fig. 2, the sealing contact surface is of a structure with a high middle part and two low ends, so that the sealing effect is enhanced.
In the present embodiment, as shown in the figure, the material of the gasket is F347H, and the hardness thereof is less than HB 180.
In the embodiment, as shown in the figure, the inner wall of the top of the transverse groove is formed by welding STL12 in a surfacing mode, and the hardness is HRC 40-HRC 45. More preferably HRC42, and the gasket has a greater hardness than the gasket, and is easily sealed.
In this embodiment, the left and right valve bodies are connected by fasteners 9 as shown. The installation is convenient.
In this embodiment, as shown in the figure, a positioning ring 111 is disposed on the left valve body, and a positioning groove 121 that is in plug-in fit with the positioning ring is disposed on the right valve body. Preferably, a gasket can be arranged in the positioning groove, and the installation is convenient.
In this embodiment, as shown, a gap 511 exists between the bottom ring 51 and the inner wall of the bottom of the transverse groove. Is convenient for pressure pushing.
