The four -pass ball valve, the "LL" four -pass ball valve only needs to operate the wrench or a actuator to rotate the sphere by 90 degrees, which can switch between the two medium flows at the same time, which is convenient and fast to achieve a multi -purpose effect.
Principles of the four -pass ball valve
1. The handle of the steel plate suppressed or the stainless steel can be used in the manual part.The handle is equipped with a limited structure, and the limit is set at the position of the valve opening and closed position. When the valve is used on the key device, the limited position is provided with a lock hole to lock the switch position to avoid error operation.There are obvious opening and closing knowledge on the handle.2. The valve stem uses A182F (1CR13) overall forging and modulating, and the hardness reaches HB220 to 250.The valve stem is connected to the handle through a flat key or flower bond or a square deed, which is strong and easy to disassemble.The valve stem has a blow -anti -blowing structure.
Four -pass ball valve structure
The small fluid resistance of the four -pass ball valve structural characteristics believes that many technical friends understand that the most critical issue of the valve is the problem of solving fluid resistance.For the four -pass ball valve, you can deal with this problem well.Its structure contains the sphere and valve body.The cross -section of the connection of these two parts is exactly equal.For the sphere channel inside, the connection method of the arc is adopted. It is precisely for this reason that when the corresponding medium is passed through the sphere, the corresponding fluid resistance is very small.
Sitong ball valve manufacturer
Shanghai Shutong Self -Control Technology Co., Ltd., why did you think of this Shanghai Shutong Self -Control Technology Co., Ltd. from the beginning because the company’s production and product series are many of them.The product series that their current companies can independently produce have reached more than 8,600 specifications. With this data, I feel that there will be no several four -pass ball valve manufacturers that the country should be able to do.
