Background
The stop valve, also called stop valve, is the most widely used valve, and it is popular because the friction between the sealing surfaces is small in the opening and closing process, it is durable, the opening height is not large, it is easy to manufacture, it is convenient to maintain, it is not only suitable for middle and low pressure, but also suitable for high pressure. The closing principle of the stop valve is that the sealing surface of the valve clack is tightly attached to the sealing surface of the valve seat by means of the pressure of the valve rod, and the medium is prevented from flowing.
The stop valve is an extremely important cut-off valve, the sealing of the stop valve is realized by applying torque to a valve rod, and the valve rod applies pressure to a valve clack in the axial direction, so that a sealing surface of the valve clack is tightly attached to a sealing surface of a valve seat, and the leakage of a medium along a gap between the sealing surfaces is prevented.
In a traditional stop valve, a rotary handle is directly connected to a valve rod, when the stop valve is opened and closed, the rotary handle drives the valve rod to rotate together, and the valve rod moves up and down through threads matched with the valve rod on a support. Like this, when the stop valve was opened and was closed, the valve rod was on one side driven the case up-and-down motion, and oneself is rotatory on one side, can lead to the wearing and tearing of acceleration case, consequently, the life-span of stop valve life is lower.
