Forged Full Brass Ball Valve

Introduction

Brass ball valves is a common valve, mainly composed of ball, seat, stem, handle, flange and so on. The sphere is a spherical structure with a perforation in the middle, and the diameter is the same as the diameter of the pipe. When the handle is rotated, the stem rotates the sphere by transmitting force, thus achieving on-off control.

Brass ball valve common faults and troubleshooting methods mainly include the following points:

leak

Leakage at the sealing surface or packing of the ball valve may be caused by wear, aging or improper installation of the seal or packing. Troubleshooting methods include replacing the seal or packing, adjusting the installation position, or reinstalling.

Sticking

The ball or stem of the ball valve is stuck, which may be caused by improper operation, impurities or dirt. The elimination methods include cleaning the inside of the ball valve. Moistening the slide valve stem or adjusting the operation mode.

Switch not flexible

The switch of the ball valve is not flexible, which may be caused by improper operation, too tight packing, and corrosion of the valve stem. Elimination methods include adjusting the operation mode, replacing the seal or adjusting the packing.

Sealing surface damage

The sealing surface of the ball valve is scratched, dented or spalling, which may be caused by impurities and hard particles in the medium. The elimination methods include cleaning the sealing surface, replacing the sealing surface or adjusting the medium.

Stem bend

The stem of the ball valve is bent, which may be caused by excessive medium pressure and excessive friction between the ball and the seat. Elimination methods include replacing the valve stem, increasing the support or adjusting the medium.

It should be noted that different troubleshooting methods are suitable for different fault situations. And various factors need to be considered comprehensively when troubleshooting. Such as fault type, use environment, media characteristics, etc., to select the appropriate troubleshooting methods and tools. At the same time, it is also necessary to pay attention to safety issues. Such as not using open flames for maintenance in flammable gas environments.
