Hot and cold water regulating pneumatic valve assembly and debugging < / div >

selectivity of hot and cold water regulating pneumatic valve is wide, the best choice is electric two-way regulating pneumatic valves, pneumatic valves are mainly used for the automatic adjustment control pipe flow degree, is suitable for heating, ventilation and air conditioning systems. Its for hot and cold water regulation is apt, working principle and operation is relatively simple. The following technology under hot and cold water regulating pneumatic valve assembly and debugging.

hot and cold water electric two-way regulating pneumatic valve assembly instructions: 1, will drive bracket set on pneumatic valve head, tighten the drive fixed screw, see picture logo position

2, the coupling nut on the pneumatic valve stem, rotation drives the power is connected, then drives the lifting nut fell to and pneumatic valve stem position, turn the power off. Then put the cup CARDS into the groove of the pneumatic valve stem, lift the coupling nut into the groove area. For debugging good position, using a wrench to tighten nut and tighten. 【 Images of different parts are clearly marked, can reference 】

3, when installation, please give priority to the vertical installation, the best choice because the pneumatic valve position when installation, the installation please leave enough space for the follow-up maintenance and removing the drive. 4, close the pneumatic valve when the power is connected, please aim the scale and the scale indicator.
hot and cold water electric two-way regulating pneumatic valve commissioning description: under the specified here, there are two kinds of wiring diagram debugging, depending on the type selection is later determined that the wiring diagram. A wiring diagram, switch mode: 1, the first debugged, pneumatic valve door lever upward or downward can breath valve 2, drive power signal at the receiving control, pneumatic valve fully open or close when blocked by a motor protector disconnect, drive motor to stop working. Second, smart wiring diagram: 1, the switching power supply pneumatic valve fully open or close the total trip, press the set key 5 - 20 seconds automatically entered into debugging, debugging fully open or close automatically trip, pneumatic valve automatic debugging time and total travel size about 4 - related Ten minutes into the working state. 2, drive to accept smart proportion controller, when the power signal input 0 VDC or 4-10 20 ma, drives the opening according to the change of schedule change, make pneumatic valve opening size can free control, pneumatic valve automatically shut down when signal power supply disappears.
