Abstract
The utility model discloses a kind of Swing check valve, comprise valve body and flap, described flap swings and is connected on shaft, and described valve body internal fixtion has mounting blocks, and described shaft comprises swing coupling shaft and fixing part, and fixing part is fixed on mounting blocks.Rotating shaft adopts the mounting blocks be fixed in valve body to fix by this Swing check valve, because the bearing pin without the need to adopting outside to insert is as rotating shaft, thus decreasing the leakage point of valve, reducing difficulty of processing simultaneously, providing cost savings.
Description
Technical field
The utility model discloses a kind of Swing check valve.
Background technique
Tradition Swing check valve flap is all adopt extrapolation pin fixation method, its structure wears the keying maincenter of a bearing pin as flap from valve body outside, the many place sealings in this structure bearing pin place, make the many place's leakage points of valve, and pin shaft hole is as the keying maincenter of flap, its difficulty of processing is large, and processing cost is high.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of Swing check valve, and the rotating shaft fixed structure processing of this Swing check valve is convenient, and sealability is better.
For this reason, the utility model realizes in the following way: Swing check valve, comprises valve body and flap, described flap swings and is connected on shaft, described valve body internal fixtion has mounting blocks, and described shaft comprises swing coupling shaft and fixing part, and fixing part is fixed on mounting blocks.
In this Swing check valve that the utility model provides, adopt the mounting blocks be fixed in valve body to fix rotating shaft, because the bearing pin without the need to adopting outside to insert is as rotating shaft, thus decreasing the leakage point of valve, reducing difficulty of processing simultaneously, providing cost savings.
