Description

A kind of air bleeding valve buffer unit

Technical field

This utility model relates to a kind of buffer unit, particularly relates to a kind of air bleeding valve buffer unit。

Background technology

During pumping plant start-stop pump, due to water hammering, the hard hit that the composite exhaust valve on supply channel continuously receives the impact to ball float of the soda pop medium, exhaust valve float ball and valve body in exhaust work process causes ball float to break or deforms, thus causing sealed valve body to leak。Visible, composite exhaust valve of the prior art has the disadvantage in that

(1) service life is short, and newly installed composite exhaust valve used for about two years will damage, and Special zone air bleeding valve uses and will damage for 1 year。

(2) maintenance cost is high, and composite exhaust valve ball float breaks and causes that whole air bleeding valve has no value for use, and can only again change。

(3) pipeline safe operation is affected, waste water resource, cause pipeline to leak operating pressure when having no effect on pipeline turn on pump because the ball float of composite exhaust valve breaks, cannot judge in staff's short time whether pipeline exists seepy question, accordingly, because the damage of composite exhaust valve ball float can cause substantial amounts of water resource utility model。
