Description

Stop valve device with flow direction adjusting function

Technical Field

The invention relates to the technical field of stop valves, in particular to a stop valve device with a flow direction adjusting function.

Background

The stop valve is also called a stop valve, belonging to a forced sealing type valve, so when the valve is closed, pressure must be applied to a valve clack to prevent a sealing surface from leaking, when a medium enters the valve from the lower part of the valve clack, the resistance to be overcome by an operating force is the friction force of a valve rod and a filler and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise, the failure of the valve rod bending can occur, and the stop valve is divided into three types according to the connection mode: flange connection, screw thread connection and welding connection. After the self-sealing valve appears, the medium flow direction of the stop valve is changed to enter the valve cavity from the upper part of the valve clack, at this time, under the action of medium pressure, the force for closing the valve is small, the force for opening the valve is large, and the diameter of the valve rod can be correspondingly reduced. Meanwhile, under the action of a medium, the valve is also tighter, the opening and closing part of the stop valve is a plug-shaped valve clack, the upper surface of the seal is a plane or sea cone surface, the valve clack moves linearly along the central line of the valve seat, and the movement form of the valve rod (the common name is a hidden rod) also has a lifting rotating rod type which can be used for controlling the flow of various types of fluid such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. Therefore, this type of shut-off valve is very suitable for shut-off or regulation and throttling. The valve rod of the valve has relatively short opening or closing stroke and reliable cut-off function, and the valve is suitable for regulating flow rate owing to the proportional relation between the valve seat port change and the valve clack stroke.

Stop valve device among the prior art is at the in-process that uses, the stop valve is one of the most extensive valve, the stop valve relies on valve lever pressure, make the sealed face of valve clack and the sealed face of disk seat closely laminate, prevent the medium circulation, the stop valve both can be done and cut the use, can do flow control and use, traditional stop valve function singleness, the problem of flow size can be controlled at any time, simultaneously take place easily to block up in the use, influence the life of stop valve, for this reason, we have proposed a stop valve device with flow direction function of regulation and have solved above-mentioned problem.
