What are the daily use and maintenance of the butterfly valve manufacturers

Butterfly valve installation precautions of gate valve manufacturers:

Gate valve manufacturer

Installation environment: The butterfly valve of the gate valve manufacturer can be used indoors and outdoors, but in the case of corrosive media and easy to rust, the corresponding material combination should be used. In special cases, please consult Zhongzhi Valve.

Installation location: Must be installed in a safe operation, easy maintenance, inspection and repair place.

Ambient temperature: -20℃ ~ + 70℃, humidity is lower than 90% RH. Before installation, check whether the valve meets the operating requirements according to the nameplate on the valve.

Before installation, remove dirt and scale from pipes. During installation, please note that the flow direction of the medium should be consistent with the flow direction arrow indicated on the valve body.

Align the center of the front and back pipes so that the flange interfaces are parallel, and lock the screws evenly. Pay attention to the pneumatic butterfly valve and the cylinder control valve. Depending on the size and weight of the cylinder control valve, provide appropriate support and fixation on the pipe or body.

Butterfly valve maintenance precautions of gate valve manufacturers:

Daily inspection: Check for leakage, abnormal noise, vibration, etc.

Regular inspection: Regularly check valves and other system components for leakage, corrosion, stuck and other phenomena, and do a good job of maintenance, cleaning, dust removal, removal of residual stains and other work.

Disassembly inspection: Periodically disassemble and overhaul the valve. During the disassembly inspection, the parts should be rinsed again, foreign objects, stains and rust spots should be removed, damaged or severely worn gaskets and fillers should be replaced, and the sealing surface should be corrected. After passing the inspection, the water pressure test should be carried out again, and it can be reused after passing the inspection.

When checking the pneumatic butterfly valve, if a liquid leak is found, do not touch or approach the cylinder control valve with your hand until it is confirmed that it is safe.

In recent years, gate valve manufacturers as a tool to control the flow of water and flow, its form has also changed. In the past, the flashlight dual-purpose gate valve was gradually replaced by the flashlight dual-purpose butterfly valve. The advantages of butterfly valve are small size, light weight, easy installation and small resistance coefficient. The traditional gate valve is not easy to leak, but the volume is large; Especially large diameter gate valve, large volume, installation and disassembly is not convenient; More importantly, due to the larger volume, the pump room area increases, and the project cost increases.

According to the structure of the butterfly valve manufacturers can be divided into offset type, vertical type, inclined type and lever type. According to the sealing form can be divided into relatively sealed type and hard sealed type. Soft seal type is generally sealed with rubber ring, hard seal type is generally sealed with metal ring.

The installation and maintenance of butterfly valves should pay attention to the following:

1. When installing, the valve disc should be stopped in the closed position.

2, according to the rotation Angle of the butterfly plate to determine the opening position.

3. The butterfly valve with a bypass valve should be opened first and then opened.

4, the installation should be carried out in accordance with the manufacturer's installation instructions, heavy butterfly valve should have a solid foundation.
