Anonymous users2024-02-14The ball valves Q341F and Q347F are both straight-through flow, worm gear drive, flange connection, and soft seal form. The difference is that Q341F is a floating ball structure, and Q347F is a fixed ball structure.
Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve; 7: Fixed ball valve, F: Fluoroplastic seat seal.
Structural differences: floating ball: the ball of the ball valve is floating, under the action of medium pressure, it is believed that the ball can produce a certain displacement and press on the sealing ring at the outlet end to ensure that the outlet end is sealed, which is a single-sided forced seal.
Fixed ball: The ball of the ball valve is fixed and does not move after being pressurized, therefore, the two sealing rings should have enough preload to ensure the sealing during the design, which is a double-sided forced seal.

Anonymous users2024-02-09The ball valve on the pipeline used to convey the attached and slag-prone medium should be full-bore, which facilitates the passage of the regular wax scraping purge. It is advisable to use a reduced diameter ball valve on the pipeline used to transport gas or a medium with physical properties similar to water, because its weight is about 30% lighter than that of a full-diameter ball valve, which is conducive to reducing the load of the pipeline and reducing the cost. Ball valve is a kind of rotary valve with a rotation angle of 90°, excellent sealing performance, (full-diameter ball valve) large flow coefficient, small flow resistance coefficient, simple structure, long service life, easy maintenance.
It is widely used in system control in chemical, petroleum, textile, electric power, food and pharmaceutical, refrigeration, and paper industries.
