Basic Knowledge of Stud Bolts

The stud is used as the cutting medium. When they are fully open, the medium pressure loss is very small. Single End Stud Bolts are generally suitable for applications that do not require frequent opening and closing and keep the valve fully open or fully closed. Not suitable for use as a regulator. Except that the disc can be lifted and lowered freely, other parts of the stud are the same as the stop valve. Under the influence of fluid pressure, the valve disc is lifted from the sealing surface of the valve seat, and the medium backflow causes the valve disc to return to the valve seat and cut off the flow. According to the service conditions, the heat sink can be of all-metal structure or other forms.

Like the stop valve, the passage of fluid through the lift check valve is also very narrow, so the pressure drop through the lift check valve is greater than that of the rotary check valve, and the flow of the rotary check valve is very small. To make the stud pressure and flow parameters meet the process requirements, and adjusting mechanism needs to be installed to adjust the above parameters. The main working principle of the regulating mechanism is to change the flow area between the Single End Stud Bolt and the valve and valve seat, to adjust the above parameters. These Single End Stud Bolts are collectively referred to as control valves.

What is the relationship between double-headed bolts and double-headed studs?

The thickness of the object connected by the Stud Bolt With Nut And Washer and the stud bolt is very large. The thread of Stud Bolt With Nut And Washer is a spiral groove with an equidistant and constant cross-sectional profile machined on the outer surface of a cylinder or cone and the inner surface of the cylinder hole or cone hole. The threaded rod or conical rod is processed on the outer surface, and the top of the stud bolt is provided with a groove for the rotation of the screwdriver or a square head clamped by hand.

Generally, the Stud Bolt With Nut And Washer needs to be equipped with a threaded nut matched with the bolt or screw on its inner surface, or a square cylinder or cylinder with a round hole inside and clamped with a square handle, such as a hexagon nut and round nut. The above is the usage of stud bolts. Stud bolts will play an endless role in some large equipment.
