Product description
The gas ball valve can be specially used for pipeline control and flow control of natural gas, gas, liquefied gas and other gas and non corrosive gas. It is suitable for long-distance transmission pipelines of natural gas, artificial coal to gas and liquefied gas and urban gas transmission and distribution pipe network. It adopts the typical two-piece floating ball structure, full dia
meter design and stainless steel ball. It has the characteristics of simple structure, convenient installation, labor-saving opening and closing operation, easy maintenance, safe and reliable performance and high corrosion resistance.
working principle
The spring column plug type static electricity export device of gas ball valve is that a conductive spring is set between the ball and the valve rod, and between the valve rod and the valve body, so as to form an electrostatic channel between the ball and the valve, and between the valve and the valve body, so as to achieve the purpose of removing static electricity. Avoid static ignition to ignite the medium and ensure the safety of the system. In case of fire, the ball valve can still operate reliably and have good sealing performance to prevent the expansion of fire.
Product features
1. Gas ball valve is a special ball valve specially designed for gas and liquefied gas pipelines. It has the advantages of small friction between sealing surfaces during opening and closing, easy maintenance and long service life.
2. PTEE (polytetrafluoroethylene) and other materials are used as seals, which have good lubricity and elasticity, small friction system with the ball and long service life.
3. It can be opened and closed quickly. When opening and closing, the hydrogen sphere only needs to rotate 90 °, which is convenient and fast
4. The fluid resistance of the ball valve is small. When it is fully opened, the cross-sectional areas of the ball channel, valve body channel and connecting pipeline are equal and straight. The medium flows through the ball valve, which is equivalent to flowing through a straight pipe. Among all kinds of valves, the fluid resistance of the ball valve is the smallest
5. Equipped with manual, worm gear drive, pneumatic and electric (explosion-proof), remote automatic control can be realized, which can meet the requirements of users under various working conditions.
Ball valves larger than DN150 are driven by worm gear.
