The installation of the axial flow regulating valve is relatively a big project. The installation is good or bad. It is completely controlled by the details. If you want to install it perfectly, you must pay attention to the following:

The axial flow adjustment valve installation part must be convenient for the actual operation: even if the installation is temporarily difficult, it will be of concern for the long-term work of the actual operation staff. The valve handwheel is aligned with the chest (usually 1.2 meters from the actual operation of the epoxy floor), so that it is easier to open and close the gate valve. The floor-standing valve handwheel should be facing upwards without skewing to prevent the actual operation from being weird. The wall-mounted machine relies on the gate valve of the machine and equipment, and it is also necessary to vacate the actual operation staff to stand up and retreat. It is necessary to prevent the actual operation of Yangtian, especially if it is strong acid and alkali, harmful substances, etc., otherwise it is very unsafe.

The sluice does not have to be flipped (ie, the handle is down), otherwise the material will remain in the bonnet interior space for a long time, it is very easy to etch the valve stem, and it is taboo for some processing regulations. It is extremely convenient to replace the filler together. The open gate valve does not have to be installed on the ground, otherwise it will erode the exposed stem due to wet and cold. The axial flow control valve should be installed with the valve flap vertical to facilitate the lift. The axial flow control valve should be installed to ensure the level of the shaft pin, which is convenient for the start and release. The pressure regulating valve should be installed on the leveling pipe without any inclination in each orientation.

Axial flow regulating valve engineering construction work:

Be careful when installing the construction. Do not hit the gate valve made of ductile raw materials. Before installation, the gate valve should be checked, the model specifications should be checked, and the damage should be assessed, especially for the valve stem. Also rotate two times to see if it is tilted. Because of the whole process, it is the most easy to hit the valve stem. Also remove the dirt inside the valve. When the gate valve is hoisted, the rope does not have to be attached to the handle or the stem to prevent damage to the member and should be attached to the flange.

Be sure to clean the piping connected to the axial flow regulator. Compressed air can be used to blow off iron oxide chips, mud sand, welding slag and other debris. This kind of dirt is not only very easy to wipe the surface of the gate valve, but also the large particles (such as welding) can block the small gate valve and make it invalid. When installing the screw gate valve, the sealing filler (line hemp aluminum oil or ptfe raw tape) should be wrapped on the external thread of the water pipe, and it is not necessary to get it into the gate valve to prevent the valve from running the memory and circumventing the hazardous materials.

When installing the axial flow regulating valve, pay attention to the symmetry of the grounding bolt. The axial flow regulating valve and the water pipe flange must be parallel to each other, and the clearance is effective to prevent the gate valve from causing excessive working pressure or even cracking. For the ductile raw materials and gate valves with too low compressive strength, it is especially important to pay attention. The gate valve to be welded with the water pipe must be welded first, then the closed part should be fully opened, and then welded.

Axial flow regulating valve safeguards:

Some gate valves must also be externally maintained, which means insulation and heat retention. Hot steam pipes are sometimes added to the insulation. Which gate valves should be insulated or heat-retained, depending on the manufacturing regulations.

In standard terms, if the axial flow regulating valve material reduces the temperature too much, it will endanger the productivity or freeze the gate valve, it must be insulated and even heat mixed; if the gate valve is exposed, it will have adverse effects on production or cause bad weather such as blooming. When you have to, you must keep warm.
