Cock Industrial Valves can into cylindrical or conical valve plug patterns. In the cylindrical plug, square channel normal growth; In the tapered plug, the channel into a ladder type. The lack of gate valves: 1. Friction damper in the beginning and end of the opening and closing process, because the operating torque is big, and easy to initiation scratches on the surface of the disc and seat tightly closed, Industrial Valves leakage; 2. No device self-checking leak, Even after two gate to install a small amount to this function, also can not succeed with semi-automatic testing functions) ; Marine valve 3. For media including particle impurities, such as sand, fill in the bottom of the valve, absolute closed gate there's no way to reach the designated position, cause the leakage of the valve is very serious, The lack of it is deadly for gate valves) 。 Beginning and end of the stem to improve type wedge plug valves, switch no friction, security valve is easy to operate, zero leakage and long term survival. Q: t cock valve and gate valve comparative analyze the answer: the 3-way plug valve is closed or plunger type rotary valve, rotated 90 degrees to make the valve plug of tong road intersection of the body through or separate, to achieve a valve open or closed. Plug valve is the most suitable for as truncation and through media and shunt is suitable for use, but according to the nature of the suit to use and tightly closed surface erosion resistance, sometimes also can be used for throttling. 3, both the top and bottom end cover, can rapidly online protection and maintenance; In line with the medium of things, just put the valve is closed, you can remove the bottom cover, can rapidly to sand, slag, eliminate a full hard particle, at the same time party is easy to change valve repair and tightly closed. 2, two meanings is broken and semi-automatic tightly closed check valve device ( DBB function, match ABV semi-automatic drain system) 。 Open valve when the valve core to progressive movement out of the seat, then no friction rotation 90 & amp; 度; To open valve; Close the valve, the valve core first without friction rotation 90 & amp; 度; , then to the seat to the absolute closed. In the process of open and close the valve, the valve core and valve seat between z there would be no friction. The style to make the structure of the cock and lighter, but also had a certain loss. 。 1, the valve stem to improve type wedge plug valves, switch to z no friction, security valve is easy to operate, zero leakage and long term survival.
