The more important thing is, the existence of curved frame and left socle can make seal ring both can play good seal action, meanwhile, does not occur again making seal ring contact with spool too closely and cause the inflexible situation of spool action.
The utility model can also adopt following technical measures: described left socle horizontal-extending.The left socle of horizontal-extending can provide horizontal support force for the seal ring be socketed on it.
The utility model can also adopt following technical measures: described spool is positioned over the concave station being fixed in bottom in valve pocket.The existence of concave station is convenient to when the handle turning valve is to drive valve core movement, very smooth and easy.
The utility model can also adopt following technical measures: described concave station side is provided with curved lower support frame and on curved lower support frame, cover has seal ring.Design is the seal approach further that the utility model provides herein.
The utility model can also adopt following technical measures: be socketed in the seal ring on curved frame and be socketed between the seal ring on lower support frame and be provided with spring.Having of spring is beneficial to as the seal ring be socketed on curved frame provides support power with the seal ring be socketed on lower support frame, makes its sealing effect better.
