Current-limiting non-return used pneumatic valve which mainly pay attention to right way

about current limit check pneumatic valve use, he can restrict the transfer of a pipeline flow, in the big traffic environment, can reduce power consumption. At the time of closing, can reduce the water hammer occurs, the effect of stable head, also can prevent the water pump in heavy traffic, a motor burn out effect. But current limit check pneumatic valve use method, requires the user to the correct use of, or would result in a pneumatic valve performance is affected.

first, install the right way to

use current limit check pneumatic valve installed correctly is very important, first of all installation suggestion is installed horizontally, so that we can guarantee the stable performance. Said on the current limit check pneumatic valve/pipe interface, is the place that must be installed in the pump inlet. Direction must not reverse installation, and installation, connection of the flange and the pneumatic valve flange must conform to the requirements, but also must be installed on the gasket and so on.

in the second place, the correct use of the

the pneumatic valve at run time, must ensure that the current limit check on all of the pneumatic valve was pneumatic ball valve, is fully open. Needle type pneumatic valve can special treatment, can open/first, according to the actual situation to adjust, so can reduce the current limit check pneumatic valve abnormal machine problem. In current limit check pneumatic valve opening to adjust the handwheel, users need to pay attention to is the handwheel must be used in the pump not into smaller before operation, or as a direct result of the handwheel rotating motionless would happen.
