The site has a closer regulation of others that can change the speed of closer efforts, this is a mistake. This will cause misunderstanding, should be the customer will speed up the lock, lock more easily, so that is the intensity bigger, in fact closer efforts is not changed, just the locking speed up, increasing the inertia, which leads to more easily buckle lock.
Closer adjustment mentioned above has been performed, on closer efforts to adjust, the door closing force and force is changing at the same time, generally the closer the greater intensity, the efficiency of the closing force and opening force more than;
Closed operation range device can be divided into three sections, respectively, the delay phase, and phase locking closed stage, the current domestic use of closers generally contains only closed phase and phase locking;
The closing stage of the door closer is: the maximum angle of the door opens to the 15 degree interval of the door; the 1 speed regulating valve (or S speed regulating valve) is controlled by the door closer;
Closing and latching device for stage: open 15 degrees to 0 degrees interval, by 2 speed control valve door closer (or L speed control valve);
The closed door closing speed and latching speed adjusted according to the user's individual needs, adjust the control valve with a slotted screwdriver or six angle wrench clockwise adjust (rotating in slow) is faster, and vice versa;
Need to pay attention to adjust the speed control valve, under normal circumstances, the end of speed control valve and the closing end flush, it can not be screwed out, if the control valve screwed out too much, will make the control valve off, product oil spills, will lead to product failure.
