Information

The manufacturer of the railway fasterer tells you that there is a disc on the inner side of the train wheel that is larger than the wheel, called the 'rim', so that the wheel is tightly stuck in the middle of the rail, which makes the wheel keep running on the track without derailment, and is used to control the train direction of operation. The train track change is not controlled by the train driver, but by a part of the rail that can move, and its name is called a switch. The railway fastener manufacturer tells you that when there is a small slit in the turnout part, the wheel rim can pass through the small slit and travel in the direction guided by the outer rail. When the two tracks are in close contact, the wheel rim is guided to the inner side of the track.

Low price railway fastener from China manufacturer
The railway fasterer manufacturer tells you that the turnout is composed of three units: the switch, the connecting part, the frog and the guard rail. The switch includes the basic rail, the switch rail and the switch machine. In addition to single turnouts, there are double turnouts, three turnouts, and multiple turnouts. The double-opening turnout is Y-shaped, that is, the two tracks connected with the turnout diverge to both sides. The three turnouts are shaped like a Ψ, and connect the three tracks at the same time, and the two sets of switch rails are controlled by two sets of switch machines. The railway fastener manufacturer tells you that the compound turnout looks like an X shape, which is theoretically equivalent to the combination of four sets of single turnouts and a pair of diamond-shaped crossings. In addition, there is a kind of crossover device, which is usually called a diamond crossover.
Each turnout has its code name, such as No. 9 turnout, No. 12 turnout, No. 18 turnout and so on. The railway fasterer manufacturer tells you that this code is not displayed randomly, it theoretically represents the cotangent value of the frog angle (α), the smaller the frog angle α, the larger the turnout number, the larger the radius of the guide curve, and the train The more bumpy the side line passes through the turnout, the higher the allowable speed of the turnout, so it is beneficial for the train to use a large turnout. However, things always have two sides. The larger the switch number and the longer the switch, the higher the cost and the larger the land occupation.
