The working principle of butt welding ball valve is like this

The closing part of the welding ball valve is a ball, which is a kind of valve that is opened and closed by rotating the ball around the center line of the valve body at 90 degrees. Straight-through ball valve is mainly used to cut off the medium in the pipeline. The structure forms are two pieces and three pieces, and the butt welding methods are socket welding, groove welding and flat. Butt welded ball valve is a new type of valve widely used in recent years, which can be installed horizontally or vertically.

Welded ball valve

Welding ball valve is connected to the welding type, the material is cast and forged, can be customized according to user requirements, can meet a variety of pressure requirements, welding ball valve selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid and other media. Butt welded ball valve is suitable for PN1.0 ~ 4.0MPa, working temperature -29 ~ 180℃(sealing ring for enhanced polytetrafluoroethylene) or -29 ~ 300℃(sealing ring for para polystyrene) of various pipelines, used to cut off or connect the medium in the pipeline. It can also be used for fluid regulation and control
Butt welding ball valve is mainly applied to the pipeline of various systems in thermal power stations to cut off or connect the pipeline medium. Applicable media: water, steam and other non-corrosive media. High pressure butt welding ball valve compared with other valve products is characterized by a unique self-sealing design, the higher the pressure, the more reliable the seal. Due to the special performance and technical characteristics and working conditions, the product has also formed the characteristics that can not be replaced by other products.
Working principle of butt welding ball valve:
Because the valve seat is composed of carbon fiber reinforced Teflon ring and disc spring, it is highly adaptable to changes in pressure and temperature, and will not produce any slip within the marked pressure and temperature range. The processing of the ball has advanced computer detector tracking detection, so the processing accuracy of the ball is high. Because the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed when the vehicle passes through the ground, and the pipe is resistant to aging. The sealing ring body is made of RPTFE with 20%Carbon(carbon) to ensure that there is no leakage (0%).
