Description

Mining floating spherical crown type adjusting stop valve

Technical Field

The invention relates to the technical field of pipeline switch control, in particular to a mining floating ball crown type adjusting stop valve.

Background

The stop valve, also called stop valve, is a valve used most widely, 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, rely on the pressure of the valve lever, make the sealing surface of the valve flap and sealing surface of the valve seat closely joint, prevent the medium from circulating, the valve plays the important role of cutting off and throttling to the medium in the pipeline where it is located, the stop valve is an extremely important cut off type valve, its seal is through exerting the torque to the valve stem, the valve stem exerts the pressure to the valve flap in the axial direction, make the sealing surface of the valve flap and sealing surface of the valve seat closely joint, prevent the medium from leaking along the gap between the sealing surfaces, the opening and, the valve flap moves linearly along the centerline of the valve seat. The motion form of the valve stem, there is lifting rotary rod too, the stop valve refers to the valve that the closing member moves along the central line of valve seat, according to this kind of movement form of the valve clack, the change of the valve seat through opening is in direct proportion relation with the valve clack stroke, because the valve stem of this kind of valve opens or closes the stroke relatively short, and have very reliable cut-off function, because the change of the valve seat through opening is in direct proportion relation with the stroke of the valve clack, very suitable for the regulation to the flow, therefore, this kind of shutoff stop valve is very suitable for cutting off or adjusting and throttle and using, in the pipe connection, multi-purpose ball valve and stop valve, there are the following drawbacks in the use of traditional on-off control valve:
