What are the common sense and skills about manual butterfly valve maintenance?Likv valve for your answer.
Manual Butterfly Valve (Manual Butterfly Valve) is a simple to operate, low cost valve type, because of its simple structure, long service life, become one of the most widely used equipment in industrial pipeline systems. However, manual butterfly valves also require regular maintenance and maintenance during use to ensure their normal operation and extend their service life. In the following content, we will introduce the basic structure, common faults and maintenance skills of manual butterfly valves in detail.
1. Basic structure of manual butterfly valve
The most basic structure of the manual butterfly valve is composed of the following parts: valve body, valve stem, bearing, handle, butterfly plate, etc. The butterfly plate is usually made of hard, wear-resistant material, usually circular, and can be rotated along the central axis to achieve the purpose of opening or closing. The handle is located between the butterfly plate and the stem, and the valve can be turned by the handle operation. The bearing supports and withstands the operating pressure of the valve.
2. Common faults
The common failures of manual butterfly valves mainly include aging of sealing materials, leakage, valve stuck and so on. Among them, the aging of the sealing material leads to leakage is a common failure situation, and the sealing gasket needs to be replaced in time to avoid secondary pollution caused by leakage. When the handle cannot rotate, it may be that the butterfly plate is stuck or solidified, and it needs to be treated to ensure the normal operation of the valve. In addition, because the handle is in a harsh environment all year round, it is vulnerable to external impact and damage, etc., so it is necessary to pay attention to regularly check whether the handle is normal, damaged and loose.
3. Maintenance skills
In order to ensure the normal operation of the manual butterfly valve, the following maintenance skills need to be taken:
(1) Ensure that the handle is firmly installed and in good working condition, and the handle screw can be fixed by the anti-loosening device.
(2) Regularly check whether the bearing and steel sleeve ring are normal, if it has been worn or deformed, it needs to be replaced in time.
(3) Try to avoid excessive force operation on the handle, so as not to affect the porosity of the valve and reduce its control performance.
(4) Regularly check whether the sealing gasket is damaged and replacing the sealing gasket is a key measure to ensure a good seal of the manual butterfly valve.
(5) In the process of various repairs, parts and cavities should be cleaned and lubricated with new lubricator oil.
To sum up, regular and correct maintenance of manual butterfly valves is the key to ensure their safe and stable operation. Here are some tips and tricks to ensure the proper operation and service life of manual butterfly valves: Avoid excessive force, check the bearing ring and steel shaft for normality, replace seal gaskets, clean parts and cavities, and lubrize with new lubricator oil.
