Hole, second mounting hole corresponding with first mounting hole is provided with the external annulus of the annular oil trap.So, assemble
During clamping ring, it can be fixed from the sidepiece of clamping ring and cover body, assembling is more convenient.
As another preferred scheme, under valve block closed mode, the clamping ring is overall above the non-return valve block.
So, only need to be by clamping ring integral raising, and can still use conventional connection coil structures.
Further preferably, the bottom of the smoke pipe connecting portion extends horizontally to ring-shaped step, the ring-shaped step to periphery
Neighboring upwardly extended rib, the ring-shaped step and rib form described installation portion.
Compared with prior art, the utility model has the advantage of：The anti-valve block glues glutinous outlet housing and passed through on cover body top
Portion's internal perisporium sets annular oil trap, and the vertical projection of the lower edge of smoke pipe connecting portion is fallen into annular oil trap, also, non-return
Sufficiently large gap is left between the lower edge of valve block and smoke pipe connecting portion so that the oil flowed down from smoke pipe connecting portion inwall can be straight
Connect and flow into annular oil trap, without being in contact with non-return valve block, will not more accumulate between valve block and clamping ring, so as to solve
The problem of valve block of having determined is sticked and do not opened by oil.
