The working principle of the three-piece ball valve
The working principle of the three-piece ball valve is as follows: One, the opening process In the closed position, the ball is pressed against the valve seat by the mechanical pressure of the valve stem. When the handwheel is turned counterclockwise, the valve stem moves ...Read more -
Floating ball valve standards and structural features (2)
6. The middle flange (the connection between the valve body and the left body) has no leakage structure. The connection between the valve body and the left body is sealed by gaskets. In order to prevent leakage due to fire, high temperature or vibration, it is specially designed to The valve bo...Read more -
Floating ball valve standards and structural features (1)
1. Structural characteristics of floating ball valve 1. Unique valve seat sealing structure. Years of ball valve manufacturing experience combined with advanced technology at home and abroad designed the double-line sealing valve seat to reliably ensure the valve seal. Professional valve sea...Read more -
The maintenance of the ball valve
The maintenance of the ball valve 1. It is necessary to find out that the upstream and downstream pipelines of the ball valve have indeed relieved the pressure before disassembling and disassembling. 2. Care must be taken to prevent damage to the sealing surface of parts, especially non-metal...Read more -
Ball valve installation
the installation of the ball valve Matters needing attention in ball valve installation Preparation before installation 1. The pipelines before and after the ball valve are ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The p...Read more -
The structure, characteristics, advantages and classification of ball valves(2)
The ball valve with a fully welded body can be directly buried in the ground, so that the internal parts of the valve are not corroded, and the maximum service life can be up to 30 years. It is the most ideal valve for oil and natural gas pipelines. According to the structure of the ball va...Read more -
The structure, characteristics, advantages and classification of ball valves(1)
The ball valve is evolved from the plug valve, it has the same 90 degree rotation lift action. The ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal internal cavity of the valve provides a straight flow channel with little resistance for...Read more -
What is a ball valve?
The ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal internal cavity of the valve provides a straight flow channel with little resistance for the medium. It is generally considered that the ball valve is most suitable for direct opening ...Read more -
What is the Advantages of ball valve ?
The Ball valve Advantages: The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length; Simple structure, small size and light weight; It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in...Read more -
What is the difference between a floating ball valve and a fixed ball valve?
The ball of the floating ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing ring at the outlet end to ensure the outlet end is sealed, which is a single-sided forced seal. The ball of the fixed ball val...Read more -
Where the ball valve is applicable
Since the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the seat sealing ring material, its use temperature is limited by the seat sealing ring material. The cut-off function of the ball valve is accomplished by pressing the metal ball against the plastic valve seat und...Read more -
The working principle of the ball valve
The ball valve evolved from the plug valve. It has the same 90-degree rotation action, but the difference is that the ball valve is a sphere with a circular through hole or channel passing through its axis. The ratio of the spherical surface and the channel opening should be the same, that ...Read more
