Silencing Check Valve Color Customer Requied for Fire Fighting
Introduction:
Silencing check valve a save-energv product, is manufactured based
on the foreign advanced technology and in accordance with relative
international standards. This product is featured by
excellentretaining perfomance, high safety and reliability and low
flow resitance. it is suitable for systems in the industries of
perochemical, food processing, medicine, textile, paper-making,
water supply and drainage, metallurgy, energy and lightindustry etc
used as a check valve in one way.
This vavle is suitable on system such as petroleum, chemical
industry, foodstuff, medicine, papemaking, water and electricity,
shipping, plumbing, the smelting and sources of energy etc the pipe
route. Can regard on gas, liquid, semifluid as well as solid powder
pipes and power lines and the container of many kinds of
corrosiveness and non-corrosiveness adjusts and dams a river the
equipment use. Especially extensively being in high layer of
building fire protection system reaches other to show in the pipes
and power lines system of valve of vavle switch state.
The disc of the wafer type butterfly valve is installed in the
diameter direction of the pipe. In the cylindrical passage of the
butterfly valve body, the disc-shaped disc rotates around the axis,
and the rotation angle is between 0°-90°, which can play the role
of flow regulation. When the disc rotates to 90°, the valve reaches
the maximum. Opening degree.
