And in use, often due to sticky oil fumes, a long time, it will be soiled. So, in the decoration will not be retained in the main flue that check valve, it should be removed, (during the renovation, in the district garbage can be seen everywhere) Only use the machine belt, because its location can be cleaned regularly.Two, according to what your text describes, it should be that the check valve on the main flue is stained.

Q:Are the common check valves stand upright or horizontally installed?: 2. swing check valves are generally installed on horizontal or vertical or inclined pipes.

Q:What's the difference between the h76x check valve h77x?: Check JB/T308-2004 "valve type programming method"The first number 7 is the clip typeThe 6 is a double valve swing structure7 butterfly check valveLook at the JB/T8937-2010 "clip on check valve"That's clear
