water pressure test stops up the valve

First, products use water pressure test stop up valve use 25MW above hydropower station boiler overheated device export and hot device imported and exported pipeline and industry pipeline system as water pressure when testing mainly Spacer assembly. Before water pressure test, pack Zhai into , rise urgent by petals of package, water pressure is it seal of two rubber of place is it is it can reach sealing very tight to enclose to seal to depend on when testing; Water pressure take out valve petals of package after testing, pack water conservancy diversion set into, valve obstruction coefficient and with to about equal pipeline have specification at this moment, so this series of products substitute the outdated worm gear transmission type and fasten the opening type ideal products which stop up the valve. Second , technical specification of the products , structure pattern and main size 1. The water pressure test stops up the valve
