Is mainly used for nominal pressure 16~140 PN, nominal size 8~50 DN low pressure, small diameter pipe, used to cut off the flow and change the flow of water distribution or for the need to quickly open and close the place.
1) small flow resistance;
2) simple structure;
3) small in size and light in weight;
4) at present, the sealing surface material of the ball valve is made of plastic, and the sealing property is good;
5) easy to operate, open and close quickly, easy to control the distance;
6) maintenance is convenient, the sealing ring is generally active, easy to remove and replace;
7) fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through the valve sealing surface will not cause erosion
1) installation position, height, import and export direction must be in line with the design requirements, thread connection should be firmly close.
2) all kinds of manual valves installed on the insulation pipe, the handle shall not be down.
3) the valve must be installed prior to visual inspection, the valve plate should be consistent with current national standard "universal valve logo" GB 12220. For the work pressure is greater than 1 MPa and in the main pipe to play the role of cut off valve, the installation should be carried out before the strength and sealing test, after passing the convenient use. Strength test, the test pressure for the nominal pressure of 1.5 times the duration of not less than 5min, the valve housing, packing should be no leakage for qualified. Seal test, the test pressure is 1.1 times the nominal pressure; test pressure test duration should meet the requirements of JB/T 9092 standard, with no leakage in the valve sealing surface as qualified.
4) the valve flange and pipe flange between the pipeline design requirements for the installation of sealing gasket.
5) with the transmission mechanism of the ball valve, according to the provisions of the provisions of the use of product installation.
