Worm gear all-welded ball valve

Worm gear all-welded ball valve

Worm wheel type all-welded ball valve, there will be no external leakage phenomenon, because the seat is made of carbonized Teflon sealing ring and coffee spring, in order to adapt to the change of pressure and temperature, marked pressure and temperature range will not produce any slip. The processing process of the ball has advanced computer detector tracking and detection, and the processing precision of the ball is high. Because the valve body material is the same as the pipeline material, there will be uneven stress, and it will not be deformed due to earthquake and vehicle passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of PTFE with a content of 20%C(carbon) to ensure that there is no leakage. All-welded ball valves are widely used in various fields. Its superior quality and high-performance stability is the ordinary cast steel ball valve can not be achieved, its service life is far greater than cast steel ball valve, all-welded ball valve is widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant and other types of pipeline equipment. Fully welded ball valve can be directly buried in the ground, without building a tall valve well to reduce the engineering cost, but also to avoid the operation of the valve caused by personnel injury, fully welded ball valve can be long-term reliable operation and use. Compared with the same specification products in the same industry, the valve body is small and beautiful in appearance.

Turbo full-welded ball valve is a new type of ball valve that can be used under high temperature and high pressure conditions, and it is named for its special welding method.
I. Structural Features
The turbo full-welded ball valve is mainly composed of valve body, ball, seat, and actuating mechanism. Its valve structure is similar to that of ordinary ball valves, but the welding method is different. Generally speaking, the valve body is made of cast steel or forged steel, the seat is set in the valve body in an embedded structure, and is welded to the valve body. The ball is connected to the seat in this way. Since the turbo full-welded ball valve is welded as a whole, its performance is more reliable than that of other types of ball valves.
II. Performance Features
1. Superior high-temperature and high-pressure performance
The turbo full-welded ball valve is mainly used in some high-temperature and high-pressure gas medium flow control systems. Its stainless steel welded structure allows it to withstand the erosion and corrosion of high temperature and high pressure, ensuring safety and reliability.
2. Good sealing performance and strong wear resistance
The ball and the seat make complete contact, effectively reducing fluid leakage, and this connection method gives it good wear resistance.
3. Flexible operation and easy maintenance
On the turbo full-welded ball valve, the rotation direction of the ball is perpendicular to the direction of the working medium flow by 90 degrees, allowing for quick opening and closing of the valve, making it flexible and convenient to operate. In addition, maintenance is also very simple.
III. Summary of Advantages
1. Able to withstand the erosion and corrosion of high-temperature and high-pressure media.
2. Smooth inlet and outlet flow paths, low flow resistance, and
 Turbo-type all-welded ball valve features:
1. The turbine welded ball valve does not require maintenance, adjustment and lubrication, and is easy to install. The valve can run reliably for a long time.
2. The valve stem can not only be lengthened or made of fine grinding, it has excellent sealing performance and corrosion resistance characteristics, and is easy to keep warm
3. The handle of the operation can be removed and can be reversed at will.
4. The valve body is free of heavy and unreliable casting components.
5. The installation and adjustment mechanism of turbo-type all-welded ball valve is very simple.

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
