結構特點(diǎn)

1.閥體采用無(wú)縫鋼管壓制成型

2.閥門(mén)的整體結構采用全焊接制造工藝，減少了外泄漏；閥門(mén)重量大大減輕，安裝更便捷

3.采用彈性墊圈及碳纖維增強密封圈，可經(jīng)受幾萬(wàn)次往復運動(dòng)無(wú)泄漏，保證閥門(mén)的使用壽命

4.閥門(mén)的密封可以在-40℃-200℃的條件下連續使用而不會(huì )失效

5.連接方式有對焊、法蘭、螺紋連接等形式，開(kāi)啟采用手柄、渦輪傳動(dòng)、電動(dòng)等方式

6.長(cháng)桿直埋焊接球閥可以深埋地下，不用設置閥門(mén)井，操作者只需在地上用手柄或渦輪傳動(dòng)機構操作即可，非常方便

7.全焊接球閥廣泛用于城市集中供熱、天然氣輸送管線(xiàn)、調壓站等領(lǐng)域，是工程首選的閥門(mén)

1.Body is adopted for seamless steel pipe to the molding.

2.The overall structure of the body can reduce the external leakage by the full weld manufacturing process; the weight of the       

valve is greatly reduced and installed much more conveniently.

3.To adopt the spring washer and carbon fiber seal ring, they can support hundred of thousands of times reciprocating motion. Thus there is no leakage; they ensure the service life of the valve.

4.The valve sealing can be used continuously without failure in the -40℃ to 200℃ situation.

5.There are many connecting methods, such as butt end, flange end and socket weld etc; there many open mode, such as handle, gear operation and electric etc.

6.Long stem buried welding ball valve can be deep-seated under ground; mean while don't set up underground valve control room. Operator can just use the handle or gear operation on the ground. It is very convenient.

7.Welded ball valve is widely used in urban central heating, natural gas transmission and regulator station and other areas. They are the top selection in construction project.
